I’m just gonna put my prediction here so it doesn’t get seen so I can compare past me who didn’t see the results of the puddles having both coward and altruism and future me, the altruism get’s unlucky and sacrifices itself to all the cowards who run away or the cowards ditch their own members after that happens so altruism wins a little bit but mostly coward win well this was kinda what I thought just the line went slightly down a little more
I think it would be interesting to introduce the mechanic of friendship. Like two blobs eat on the same tree and survive, they happen to be acquaintances. If that happens again, they become friends, increasing the chance to save each other after approaching a predator.
"It can sometimes take surprisingly long for random events to even out, which is my favorite excuse whenever I'm getting my butt kicked in a board game" Got me rolling
The diploid model isn't linked to how many alleles there are, is it? You may still just have two, but you can have a form where you might have both of them. So what might happen, is that you get one selfish and one altruistic copy and then the question is how that changes expression. It might end up being a dominance thing where having one of the variants means you fully express that, or it might be some sort of percentage thing where you simply change the chance of, in this case, yelling, or a third thing might happen, like a specific gene in certain mice that changes fur color from grey to beige if they have one copy, but if they have *two* copies the mouse is stillborn. The explanation for why that can possibly work is because that make beige mice rarer and so predators are less likely to specialize in spotting them, so they are more likely to survive, apparently. Enough so that it seems to outweigh the lost number in offspring But at any rate, it's possible to have just two alleles even in diploid genetics. The thing that might increase is the number of phenotypes (there might be three phenotypes with just two alleles of a gene, one of which happens if you have both alleles)
@@malaineeward5249 50%, the kind coward gene. 50% chance to run and 50% chance to stay. It'd make more sense and more dynamic than, say, if you have a mixed set, there's a 50% chance you'll end up as either.

@@bpansky A basic understanding of economies should grant that knowledge tbh. It's not rocket science. But I'll go look anyway. The fact is that most articles are one sided explanations not allowing the dissection of premises, as authors tend not to like that much. But as I said, I'll go look. Wow. This guy quotes himself as a source. I haven't seen any statistical data yet, it's more like someone just hit his ego and he's on a rant. I'll keep going in the hopes of finding gold in this trash pile, but thoroughly unimpressed so far. And ironically the computer simulation he's basing that on, and it's very close to real life results... it's because it was designed to get that result. In the real world we see advancements heavily reflected by iq up to about the 150 threshold where it becomes a negative not a positive. Hilarious to base so much while not understanding the flaw in the initial. The luck value is a reflection of iq which of course looks like luck if you don't understand the positioning to achieve "luck". Even they acknowledged skill as a major factor on top. And a UBI argument isn't valid in theirs anyway, he misunderstood the tail end of their paper. That wouldn't create more opportunity for talent anyway, just freeing up the capital lock at the top is their point, we're overrewarding scale versus talent. And all of this measured success as though money wasn't bids for resources, the heart of the failure is right there as it's a competitive debt bidding in essence. Adding more to the pool just increases the bids. Inflation is really just this, a UBI is just adding more the to base of broke. 0 effectively becomes a slightly higher value, but is a new equivalent of 0.

"My reasoning is flawless. I never do a mistake. Let allone put it on youtube" nice self shading. Also the blob's yelling animation is cute as all heck
Since we saw cowardice and altruism, I would be curious to see the breakdown for the blobs fighting against the predators, some who survive and some who are physically capable of overwhelming it, or even defeating the predator through teamwork
So two pairs of two alles? With each competing alle being on a spot on the same axis? So 1) = Coward vs Assessor vs Altruistic & 2) = Strong vs Fit vs Weak. Then test to see if impacting other alles & vice versa affect gene domination?
I wish i knew how to set up simulations like this, would solve a lot of my "i wonder" scenarios. I love how you break everything down in your videos. Each one is very informative and thorough. Best randomly suggested creator I've gotten from UA-cam since they started doing that 😂
An interesting thing to look into would be cases where saving others also end up saving harmful genes that objectively lower the chance of survival, knowingly or otherwise. Morality and ethics aside, it would be an interesting experiment.
It kinda happened with the alleles in this one, since your siblings are kind of random, so since you sacrifice yourself for them. You can save cowardly alleles. But as we saw, with an even number of participant and an even chance of survival, on average it evens out.
Isn't that just the prisoners dilemma with someone trusting? Let's say there's 2 alleles, one who always cooperates, one who always betrays. By cooperating with a betrayer you make the whole population worse off.
It might also be interesting to introduce the possibility of recognizing relatives. As far as I know this happens a lot of different ways in the wild, but in humans we get a little more complicated due to "psuedokinship" where we consider people who aren't blood relatives as brothers or sisters.
ie people who we subconsciously understand to be genetically similar, who, if we help, we will be passing in more of our genes than someone who is dissimilar.
@@Lankpants Note the comment- "recognizing relatives"- not siblings- and "'psuedokinship' where we consider people who aren't blood relatives as brothers or sisters". this implies having more people on a blob's radar, so it's no longer just the 2 blood siblings displayed already.
@R. L. G. "The science of racial favouritism" Mostly. Though it would require next step and going in to group level selection when one would clash with another group of blobs for resources. In top level simulation it require positive (cooperate with your kin) and negative (fight outsiders) ethnocentrism plus mechanism for disciplining/eliminating disloyal group members.
I'd like to explore the diploid situation with the question of what effects having both alleles would have considering things like trait dominance or co-dominance.
@Dafork_gaming Well, it’s always a win for the blobs in general since being altruistic saves 2 at the cost of 1 but it’s can be a loss for the altruists since they can either lose one of their members to save 2 cowards blobs, either win if they lose one of their member to save two altruistic blobs or lose one altruist to save another altruist and a coward, making saving others a gamble for them. And you can’t use the fact that the cowards lose nothing since, if we take the number of this allele’s carriers in consideration, escaping when the two others are also cowards is the best for the individual, since they always survive, but it’s not the best for the allele since the blob’s comportement cost the life of two others carriers to save his own even if he could save both in exchange for his life. Moreover, in real life, it’s also depends on the situation since the probabilities can be altered by a number of factors (for the altruists, if they are lucky or in good physical condition, they can yell without being eaten, depending of the situation, they can save more or less life with more or less risks, likewise, for the cowards, they doesn’t always have 100% to escape, they can even be in a situation where nobody can escape if nobody sacrifice himself to make diversion, so, if there’s only cowards, they all die) and also, it’s rarely as simple as that, even cowards can probably help to save someone if they isn’t any risks and altruists will not always save someone if it can cost the life of more people than it save (especially if there isn’t a great chance to save these people without anybody dying)
You could do it with more than just two genes, say you did it with ten different genes, giving a percentage chance of doing an action. So if one of the blobs has more altruistic genes rather than cowardly genes, then they have a percentage chance of choosing either altruism or cowardice. And you could have a percentage chance of altruism getting every blob killed anyways, depending on the predators. Say a predator kills a blob, then the predator could have a percentage chance to evolve to try and kill more, or a chance to become lazier and end up not killing anything if an altruist were to tell the other blobs of the predator.
@@clumpus2012 If we go down this road, we also need to simulate a lot of different things like the learning of the creatures with experience(blobs and predators), their level of skill (compare the one of the blobs vs the one of the predator to know the pourcentage of chance the blob end up killed), maybe the share of knowledge, the evolution of their civilisation and a lot of others things to really compare it to the real world so it’s not really worth it in this case. For example, with the 10+ genes, introduce more complexity at the genetic level will not suffice since not only there’s a part of innate but also a part of experience/education in this sort of decision.

If there is 95% on both sides it would result in the same with the 100% chance. But the random possible extinction would take longer than with 100% chance. Also if there is 95% on one side, it will have the same result as what was shown with the altruistic behavior. At least, in theory.

Imagine he combines them all into one godly life simulator, here's some ideas: 1. Starts out with the blobs fighting for food and evolving, landscapes will change how much food places have, some blobs will help the other get food or save them from danger with a chance to get hurt and when no food is left they fight or split it, ones working together could help fight off attackers. 2. After there's a dominate species in all the 'regions' they build houses and civilizations with leaders, still fighting over food in areas with less blobs. Some open shops and maybe fight over land and resources. Maybe some leaders/civilizations could have different economic laws that change how many businesses there are, how much they make, and how they feel about the leader. Perhaps add in rebellions? 3. Stops when everyone dies or one country rules all. Yeah that got kinda complicated but imagine how cool it'd be! Feel free to add some in replys or correct something.
Yeah, it would be insane Eventually we could make a simulation that literally ends up being an alternate reality of our world-- Different things happening, different people, but still Earth.
I dont get why everyone always assumes that humanity must naturally be competitive... We are by nature a social species, that only managed to survive and progress through COOPERATION and DESPITE the constant anti-social behavior of a single minority We, as the united race of humanity, have nothing else to desire and to strive for than the total association of the free human, based on mutual help and the common fight against our common enemy
One thing that strikes me when I try to link this simulation to actual nature, is that organisms that display this kind of behaviour irl have tons of offspring and live in large groups, like rabbits or meerkats (meerkats actually yelp and rabbits pound the ground with their feet). This would give the "sacrifice" behaviour a higher expected payout than the blobs, who only produce 3 offspring at a time.
Either that or they tend to be more social species that have other ways to detect and avoid animals that don't abide by social norms like acting fairly and cooperatively. This tends to be the case with a lot of larger mammals that have small litter sizes for example. There the benefits of the uncooperative behaviour are often mitigated socially by limiting access to group resources, mating opportunities or even abandoning members of the group that do not cooperate. But then I guess this is in a sense a really developed system for detecting group members that have or don't share those genes. And it is something of an evolutionary arms race there since this requires a brain capable of a fairly complex theory of mind which itself opens up a new strategy for cheating the system since this is both the very thing you can iterate on to develop deception and a selection pressure for that to be beneficial.
As the other person has said, in real life the behavior would also be beneficial to groups of animals that have very few offspring, because if they don't help each other to survive they could straight up just go extinct if the only offspring is lost for example.
@@TheSilverwing999 Hamilton's rule posits that the benefits of altruism increase with the number of offspring. You would expect that the rate of altruism decreases with smaller "puddles" of children.
When I was watching the blob throw the dice while you were calculating the probability, I had this imagery of the blob in the box throwing the dice and being happy when it got six, and then looking over to see its dad/creator off to the side writing down numbers on a massive whiteboard. I don't know why the image of that is so cute to me, but it is.
Request: could you do “simulating teamwork and defense” There are 5 blobs on each side of a court, 1 red side and 1 blue side, at the beginning, they will pick a ball, if a blob gets hit, they’ll have to go to the waiting bench, they have 2 roles on each team, the teammates and the defenders, the defender can block a ball and not get out, but they can get hit after 3 blocks, if 1 team loses, the simulation ends
@@wileymcgraw5511 You don't get the joke? Okay, I'll explain; there have been some recent news articles claiming that we've developed a warp drive in real life. But as usual for pop science articles, reporters have taken a kernel of truth (scientists have revised the theoretical limits on FTL travel based on new understanding of quantum mechanics), and blown it out of proportion (we've invented a warp drive and the whole galaxy is now ours to command).
Actually, alerting others and getting eaten is more similar to screams victim makes before getting eaten. Not intentional altruism but systemic altruism nonetheless. In such sense, the result where altruism dominates cowardice almost completely is true because people would normally scream when meeting a danger, excepting special occasion where one is trained not to.
irl maybe it can backfire, like someone screaming reveals where others are hiding, or getting more (altruistic) people over to help them, putting them in danger.
Many many many many animals that are not social, and have no expectation anyone is going to come to the rescue, still have the urge to scream when in pain instead of saving their breath to fight/flee with. Animals may do this to startle a predator, but a definite systemic-altruism bonus involved is that any animal of the same species nearby who hears the scream is gonna book it away from whatever hurt them, and potentially avoid danger. Hell, animals of other species will bum off some of that altruism and run, too.
It's funny, I had a totally different expectation as to how the simulation would fail to meet expectations. A similar idea, but based in the logic of the simulation, not the underlying math. See, within a puddle, an altruistic blob will kill themselves to save the rest of their group, while a cowardly blob becomes sole survivor. This means that every time a puddle encounters a predator, either: 1. an altruist dies, and altruists survive or 2. an altruist dies, and a mixed group survives or 3. an altruist dies, and cowards survive or 4. cowards die, and a coward survives My hypothesis was that, since the only time a coward dies is when there are no altruists in the group at all, the coward population has better odds of propagation. Every time an altruist pairs with a coward, but all three offspring are also cowards, the coward population surges up in the next generation, whether that group encounters a predator or not. However, this explanation is also incomplete, since I neglected the fact that every pure puddle pairing results in either one altruist death or four coward deaths, a huge disparate number. It turns out that there's an extreme level of variance in the simulation's output for early generations, which results in the broad range of outputs in the video. In a simulation where the first generation mostly pairs like with like, the bias _should_ favor altruists from then on out, as the second gen altruists have a much higher survival rate. By contrast, if the early generations of the simulation mostly form mixed couple puddles, there should be more altruist deaths than coward deaths overall, unless we see a disproportionately low amount of one altruist four coward puddles. Due to the swingy nature of the early generation's impact on the whole, and the complex series of circumstances that need to happen for either gene to eclipse the other, I'd be really interested to see what this simulation looks like with much larger starting populations. It would be also be worth experimenting with a bias for altruists to pick altruist partners and cowards to pick coward partners, or to enforce that blobs pair off to reproduce at a fixed rate relative their share of the total population, rather than leaving it to pure chance. If trying to represent a large population, either the puddle families are split geographically and more likely to mingle with their own kind purely based on relative location, or the gene is spread more evenly, and a fixed ratio would do better to estimate whole populations dramatically larger than the sample size.
I guess we didn't have the same perception of the mechanics of this simulation. How I read it, one of the blobs at random from the puddle was picked to notice the plant (if one was present). With that reading, you would be able to have a cowardly blob die if you have two cowardly blob and an altruistic blob, where the other cowardly blob notices the plant and runs away. For my calculations, I have said that plants live in 50% of the trees. If we list the expected survival composition of a puddle born to specific parents as (a, c) where a = surviving altruists and c = surviving cowards, we would get: (C, C) -> (0, 2) (C, A) -> (1, 1.25) (A, C) -> (1, 1.25) (A, A) -> (2.5, 0) If we average these out, we get an expected value of (1.125, 1.125), and would therefore expect the populations to remain equal (which seems to be what the average shows in the video and what the analysis with Hamilton's Rule seems to suggest). Doing the same calculations, but stipulating that a cowardly blob can only be the one to spot the plant if no altruist is present, we would instead get the numbers: (C, C) -> (0, 2) (C, A) -> (1.0625, 1.375) (A, C) -> (1.0625, 1.375) (A, A) -> (2.5, 0) This would average out to around (1.156, 1.188), very slightly in favour of the cowardly blobs. Since we are limited by housing, I have also normalized these values to (0.987, 1.013), so given enough time, we would expect the altruistic blobs to finally die out in that situation, but considering how close to 1 both values are, I would expect it to take a while.

When he asked if the viewer could figure out the flaw, the first thing that came to my mind was: You forgot about the cowards, who are going to let possible altruistic blobs die.
We need a crossover episode where every gene you've covered is added into a simulation, the plants, speed, reproduction chance, stealing chance, sacrificial behaviour and there's gonna be rainbow blobs everywhere that'd be epic
10:11 Its pretty fitting to stick with haploid organisms for this video, seeing as bees, who show basically the extreme version of this behavior, are also haploid.
No no, bees are a more complicated case. They aren't haploid, they're haplodiploid: the males (drones) are haploid and the females (queens and workers) are diploid. This means that all bee siblings inherit the same genes from their father's part, therefore the average relatedness between them is 75% instead of the usual 50%. This means they share more genes with their siblings than with their parents. Worker bees are sterile, but by taking care of their fertile siblings they technically contribute more to the survival of their genes than by having offsprings on their own.
@@matyaskassay4346 Riiiiight thats how it was. I thought I remembered there being some other stuff that complicated things but couldnt quite recall what it was.
Id love to see some simulations surrounding the idea of social capital, I know it would be difficult to figure out how but as a sociologist it would be incredible to see. Something like different groups (societies?) of blobs having a social capital score with a chance each increment for a blob group to gain or loose social capital (representing social change), the social capital score would increase the likelihood each individual blob would sacrifice itself for the fellow blobs in its group/society, and demonstrate how this effects these blob societies over time.

* This jideo just tells that the difference between games that good team understand sacrifice of support, and when will the other don't then be dead. ( From League of Legends ) *
Reminder: The idea that 'a gene' can map to a 'behavior' as nebulous and one dimensional as 'sacrificing' (or any other term) is essentially impossible. It's impossible not just because we don't understand biology fully or neuropsychology, it's impossible because we have extremely poor frameworks for even describing behavior at a macro level that are internally consistent. This is a fun concept, but don't take it too seriously, as we can't apply this to reality and still claim to know what we're talking about.
You know, i understand that this channel is all about showing the estimated values of certain events and all, but the only questions i’d want answered are how big are blobs compared to human size, what noises do blobs make and most importantly, can i pet a blob?

You're great at explaining complex terms. When I start your video in the middle I completely don't know what you're talking about. But when I start at the beginning and listen closely it's sooo easy to follow.
When the puddle goes to a tree and seeing how they're siblings and have the same genetics. Wouldn't they all yell to save each other? Killing them all?
It was stated during the first simulation involving predators that only one blob notices the predator, so only one blob actually yells or flees, depending on it's gene, and the other two live or die no matter their gene

Another two factors you could look at: Altruists being more likely to be taken advantage of. They would be more likely to find a predator, because they go to the tree first. Cowards being less likely to find a partner due to them being less appealing in terms of safety.

This was really well executed and explained! I did figure out beforehand the alleles would be evenly matched, but my explanation for it was kind of off and your explanation was much clearer, with the "not identical by descent" chance not having an effect. It made sense after thinking about it for a couple of minutes. Interesting how a somewhat complicated set of variables condenses into such a tidy rule.
and frankly I am really upset that they didn't clarify the loose end of relatedness. Why the heck does the same allele happening not matter just because it came from a different parent. They're in the same value search of increase population. What is the issue with including them? That generations point wasn't thoroughly enough explained.

I think it would be interesting to introduce the mechanic of friendship. Like two blobs eat on the same tree and survive, they happen to be acquaintances. If that happens again, they become friends, increasing the chance to save each other after approaching a predator.
Wow thats actually a really good idea!
And they may help each other out if one of them got food then they could share instead of leaving the friend go hungry

The diploid genetics would show a more realistic and varied simulation as well as more types of alleles, I would really like that!
not sure how he would deal with heterogeneous individuals tho
@@turtlememes2334 he'd have to decide which allele was dominant. Or there'd be a 50-50 chance. 3 possible simulations to try.
The diploid model isn't linked to how many alleles there are, is it? You may still just have two, but you can have a form where you might have both of them.
So what might happen, is that you get one selfish and one altruistic copy and then the question is how that changes expression.
It might end up being a dominance thing where having one of the variants means you fully express that,
or it might be some sort of percentage thing where you simply change the chance of, in this case, yelling,
or a third thing might happen, like a specific gene in certain mice that changes fur color from grey to beige if they have one copy, but if they have *two* copies the mouse is stillborn.
The explanation for why that can possibly work is because that make beige mice rarer and so predators are less likely to specialize in spotting them, so they are more likely to survive, apparently. Enough so that it seems to outweigh the lost number in offspring
But at any rate, it's possible to have just two alleles even in diploid genetics. The thing that might increase is the number of phenotypes (there might be three phenotypes with just two alleles of a gene, one of which happens if you have both alleles)
@@malaineeward5249 50%, the kind coward gene. 50% chance to run and 50% chance to stay. It'd make more sense and more dynamic than, say, if you have a mixed set, there's a 50% chance you'll end up as either.
Which should be dominant tho

Wow. This guy quotes himself as a source. I haven't seen any statistical data yet, it's more like someone just hit his ego and he's on a rant. I'll keep going in the hopes of finding gold in this trash pile, but thoroughly unimpressed so far. And ironically the computer simulation he's basing that on, and it's very close to real life results... it's because it was designed to get that result. In the real world we see advancements heavily reflected by iq up to about the 150 threshold where it becomes a negative not a positive. Hilarious to base so much while not understanding the flaw in the initial. The luck value is a reflection of iq which of course looks like luck if you don't understand the positioning to achieve "luck". Even they acknowledged skill as a major factor on top. And a UBI argument isn't valid in theirs anyway, he misunderstood the tail end of their paper. That wouldn't create more opportunity for talent anyway, just freeing up the capital lock at the top is their point, we're overrewarding scale versus talent.
And all of this measured success as though money wasn't bids for resources, the heart of the failure is right there as it's a competitive debt bidding in essence. Adding more to the pool just increases the bids. Inflation is really just this, a UBI is just adding more the to base of broke. 0 effectively becomes a slightly higher value, but is a new equivalent of 0.

An interesting thing to look into would be cases where saving others also end up saving harmful genes that objectively lower the chance of survival, knowingly or otherwise.
Morality and ethics aside, it would be an interesting experiment.
It kinda happened with the alleles in this one, since your siblings are kind of random, so since you sacrifice yourself for them. You can save cowardly alleles.
But as we saw, with an even number of participant and an even chance of survival, on average it evens out.
Isn't that just the prisoners dilemma with someone trusting?
Let's say there's 2 alleles, one who always cooperates, one who always betrays. By cooperating with a betrayer you make the whole population worse off.

You should combine all of these simulations together into one, massive, super sim and see what happens
It might also be interesting to introduce the possibility of recognizing relatives. As far as I know this happens a lot of different ways in the wild, but in humans we get a little more complicated due to "psuedokinship" where we consider people who aren't blood relatives as brothers or sisters.
The science of racial favouritism
ie people who we subconsciously understand to be genetically similar, who, if we help, we will be passing in more of our genes than someone who is dissimilar.
The way the sim was running this was already the case. The blobs were only going out and hunting with their siblings.
@@Lankpants Note the comment- "recognizing relatives"- not siblings- and "'psuedokinship' where we consider people who aren't blood relatives as brothers or sisters".
this implies having more people on a blob's radar, so it's no longer just the 2 blood siblings displayed already.
@R. L. G. "The science of racial favouritism" Mostly. Though it would require next step and going in to group level selection when one would clash with another group of blobs for resources. In top level simulation it require positive (cooperate with your kin) and negative (fight outsiders) ethnocentrism plus mechanism for disciplining/eliminating disloyal group members.
I'd like to explore the diploid situation with the question of what effects having both alleles would have considering things like trait dominance or co-dominance.
+1
@Dafork_gaming Well, it’s always a win for the blobs in general since being altruistic saves 2 at the cost of 1 but it’s can be a loss for the altruists since they can either lose one of their members to save 2 cowards blobs, either win if they lose one of their member to save two altruistic blobs or lose one altruist to save another altruist and a coward, making saving others a gamble for them.
And you can’t use the fact that the cowards lose nothing since, if we take the number of this allele’s carriers in consideration, escaping when the two others are also cowards is the best for the individual, since they always survive, but it’s not the best for the allele since the blob’s comportement cost the life of two others carriers to save his own even if he could save both in exchange for his life.
Moreover, in real life, it’s also depends on the situation since the probabilities can be altered by a number of factors (for the altruists, if they are lucky or in good physical condition, they can yell without being eaten, depending of the situation, they can save more or less life with more or less risks, likewise, for the cowards, they doesn’t always have 100% to escape, they can even be in a situation where nobody can escape if nobody sacrifice himself to make diversion, so, if there’s only cowards, they all die) and also, it’s rarely as simple as that, even cowards can probably help to save someone if they isn’t any risks and altruists will not always save someone if it can cost the life of more people than it save (especially if there isn’t a great chance to save these people without anybody dying)
You could do it with more than just two genes, say you did it with ten different genes, giving a percentage chance of doing an action. So if one of the blobs has more altruistic genes rather than cowardly genes, then they have a percentage chance of choosing either altruism or cowardice. And you could have a percentage chance of altruism getting every blob killed anyways, depending on the predators. Say a predator kills a blob, then the predator could have a percentage chance to evolve to try and kill more, or a chance to become lazier and end up not killing anything if an altruist were to tell the other blobs of the predator.
@@clumpus2012 If we go down this road, we also need to simulate a lot of different things like the learning of the creatures with experience(blobs and predators), their level of skill (compare the one of the blobs vs the one of the predator to know the pourcentage of chance the blob end up killed), maybe the share of knowledge, the evolution of their civilisation and a lot of others things to really compare it to the real world so it’s not really worth it in this case. For example, with the 10+ genes, introduce more complexity at the genetic level will not suffice since not only there’s a part of innate but also a part of experience/education in this sort of decision.

1. Starts out with the blobs fighting for food and evolving, landscapes will change how much food places have, some blobs will help the other get food or save them from danger with a chance to get hurt and when no food is left they fight or split it, ones working together could help fight off attackers.
2. After there's a dominate species in all the 'regions' they build houses and civilizations with leaders, still fighting over food in areas with less blobs. Some open shops and maybe fight over land and resources. Maybe some leaders/civilizations could have different economic laws that change how many businesses there are, how much they make, and how they feel about the leader. Perhaps add in rebellions?
3. Stops when everyone dies or one country rules all.

3:30 that blob didn’t roll 5 a single time in 25 roles which has slightly less than a 1.05% chance of happening.
Yeah, it was weird, but the long-run results were fine.
One thing that strikes me when I try to link this simulation to actual nature, is that organisms that display this kind of behaviour irl have tons of offspring and live in large groups, like rabbits or meerkats (meerkats actually yelp and rabbits pound the ground with their feet). This would give the "sacrifice" behaviour a higher expected payout than the blobs, who only produce 3 offspring at a time.
Either that or they tend to be more social species that have other ways to detect and avoid animals that don't abide by social norms like acting fairly and cooperatively. This tends to be the case with a lot of larger mammals that have small litter sizes for example. There the benefits of the uncooperative behaviour are often mitigated socially by limiting access to group resources, mating opportunities or even abandoning members of the group that do not cooperate. But then I guess this is in a sense a really developed system for detecting group members that have or don't share those genes. And it is something of an evolutionary arms race there since this requires a brain capable of a fairly complex theory of mind which itself opens up a new strategy for cheating the system since this is both the very thing you can iterate on to develop deception and a selection pressure for that to be beneficial.
As the other person has said, in real life the behavior would also be beneficial to groups of animals that have very few offspring, because if they don't help each other to survive they could straight up just go extinct if the only offspring is lost for example.
@@TheSilverwing999 Hamilton's rule posits that the benefits of altruism increase with the number of offspring. You would expect that the rate of altruism decreases with smaller "puddles" of children.

Actually, alerting others and getting eaten is more similar to screams victim makes before getting eaten. Not intentional altruism but systemic altruism nonetheless.
In such sense, the result where altruism dominates cowardice almost completely is true because people would normally scream when meeting a danger, excepting special occasion where one is trained not to.
Screaming is not necessarily altruism, it could be to call for help.
irl maybe it can backfire, like someone screaming reveals where others are hiding, or getting more (altruistic) people over to help them, putting them in danger.
@@nicolew4710 but it could also gain you help from people who pass by.
@@nicolew4710
Perhaps, but most predators prefer to ambush, so they REALLY don’t want the extra attention
Many many many many animals that are not social, and have no expectation anyone is going to come to the rescue, still have the urge to scream when in pain instead of saving their breath to fight/flee with. Animals may do this to startle a predator, but a definite systemic-altruism bonus involved is that any animal of the same species nearby who hears the scream is gonna book it away from whatever hurt them, and potentially avoid danger. Hell, animals of other species will bum off some of that altruism and run, too.
It's funny, I had a totally different expectation as to how the simulation would fail to meet expectations. A similar idea, but based in the logic of the simulation, not the underlying math.
See, within a puddle, an altruistic blob will kill themselves to save the rest of their group, while a cowardly blob becomes sole survivor. This means that every time a puddle encounters a predator, either:
1. an altruist dies, and altruists survive
or
2. an altruist dies, and a mixed group survives
or
3. an altruist dies, and cowards survive
or
4. cowards die, and a coward survives
My hypothesis was that, since the only time a coward dies is when there are no altruists in the group at all, the coward population has better odds of propagation. Every time an altruist pairs with a coward, but all three offspring are also cowards, the coward population surges up in the next generation, whether that group encounters a predator or not.
However, this explanation is also incomplete, since I neglected the fact that every pure puddle pairing results in either one altruist death or four coward deaths, a huge disparate number. It turns out that there's an extreme level of variance in the simulation's output for early generations, which results in the broad range of outputs in the video.
In a simulation where the first generation mostly pairs like with like, the bias _should_ favor altruists from then on out, as the second gen altruists have a much higher survival rate. By contrast, if the early generations of the simulation mostly form mixed couple puddles, there should be more altruist deaths than coward deaths overall, unless we see a disproportionately low amount of one altruist four coward puddles.
Due to the swingy nature of the early generation's impact on the whole, and the complex series of circumstances that need to happen for either gene to eclipse the other, I'd be really interested to see what this simulation looks like with much larger starting populations. It would be also be worth experimenting with a bias for altruists to pick altruist partners and cowards to pick coward partners, or to enforce that blobs pair off to reproduce at a fixed rate relative their share of the total population, rather than leaving it to pure chance. If trying to represent a large population, either the puddle families are split geographically and more likely to mingle with their own kind purely based on relative location, or the gene is spread more evenly, and a fixed ratio would do better to estimate whole populations dramatically larger than the sample size.
I ain't reading allat🔥🔥🔥💯💯💯
I guess we didn't have the same perception of the mechanics of this simulation. How I read it, one of the blobs at random from the puddle was picked to notice the plant (if one was present). With that reading, you would be able to have a cowardly blob die if you have two cowardly blob and an altruistic blob, where the other cowardly blob notices the plant and runs away. For my calculations, I have said that plants live in 50% of the trees. If we list the expected survival composition of a puddle born to specific parents as (a, c) where a = surviving altruists and c = surviving cowards, we would get:
(C, C) -> (0, 2)
(C, A) -> (1, 1.25)
(A, C) -> (1, 1.25)
(A, A) -> (2.5, 0)
If we average these out, we get an expected value of (1.125, 1.125), and would therefore expect the populations to remain equal (which seems to be what the average shows in the video and what the analysis with Hamilton's Rule seems to suggest).
Doing the same calculations, but stipulating that a cowardly blob can only be the one to spot the plant if no altruist is present, we would instead get the numbers:
(C, C) -> (0, 2)
(C, A) -> (1.0625, 1.375)
(A, C) -> (1.0625, 1.375)
(A, A) -> (2.5, 0)
This would average out to around (1.156, 1.188), very slightly in favour of the cowardly blobs. Since we are limited by housing, I have also normalized these values to (0.987, 1.013), so given enough time, we would expect the altruistic blobs to finally die out in that situation, but considering how close to 1 both values are, I would expect it to take a while.

A breakdown on how you program the simulations in Unity would be pretty cool
I want this so much. I really want to put this into some kind of excel or matlab "simulation" that would generate but I always feel like the imagination/creative portion of it shoots me down. I'd love a behind the scenes look!
I'm a biologist and I simply love your videos. They are really informative and easy to understand!
I've used them in class when I was working as a teacher and my students also loved them.
With only Altruistic Allele, everyone eventually gets stuck in a ”No, you first” loop.
And thats how Canada came into being
Plot twist: They yell at the same time, which confuses the predator allowing all 3 blobs to survive.
When he asked if the viewer could figure out the flaw, the first thing that came to my mind was:
You forgot about the cowards, who are going to let possible altruistic blobs die.
That was my thought as well.
Ye same I thought that the cowards would let cowards live every time while altruism could be helping cowards or ealtrisms lowering the chance
Cowards will not mate because other blobs know they will be betrayed
@@plexiglasscorn that’s entirely incorrect lmao
@@grelkie i know 😂
We need a crossover episode where every gene you've covered is added into a simulation, the plants, speed, reproduction chance, stealing chance, sacrificial behaviour and there's gonna be rainbow blobs everywhere that'd be epic
I love the idea of having rainbow blobs
But what would we learn?
@@jaideepshekhar4621 yes
Nah bro that’s cheating we can’t have invincible blobs
i literally just found this channel today and i’m love with the blobs they’re so cute 😭😭😭

Just the comment I was looking 4
10:11 Its pretty fitting to stick with haploid organisms for this video, seeing as bees, who show basically the extreme version of this behavior, are also haploid.
No no, bees are a more complicated case. They aren't haploid, they're haplodiploid: the males (drones) are haploid and the females (queens and workers) are diploid. This means that all bee siblings inherit the same genes from their father's part, therefore the average relatedness between them is 75% instead of the usual 50%. This means they share more genes with their siblings than with their parents. Worker bees are sterile, but by taking care of their fertile siblings they technically contribute more to the survival of their genes than by having offsprings on their own.
@@matyaskassay4346 Riiiiight thats how it was.
I thought I remembered there being some other stuff that complicated things but couldnt quite recall what it was.
I have no issue putting down the four personal projects I can never seem to finish just so I can watch a new Primer video.
Bro 😁 he uploads like once a year, I think you can take a break once a year
Id love to see some simulations surrounding the idea of social capital, I know it would be difficult to figure out how but as a sociologist it would be incredible to see.
Something like different groups (societies?) of blobs having a social capital score with a chance each increment for a blob group to gain or loose social capital (representing social change), the social capital score would increase the likelihood each individual blob would sacrifice itself for the fellow blobs in its group/society, and demonstrate how this effects these blob societies over time.
It works in a similar way as this simulation then then if you're saying the bigger number of social capital= more altruism in this case
@@randomlygeneratedname in a sense yes
I absolutely LOVE how you talk through the equations you show. It's what I find most helpful when trying to understand new equations myself and help others do the same.

If this man was a university teacher every student would pass with an A+, the only downside is they'd be over 100 by the time 1 semester's worth of content is finished
Edit: Woah that's a lot of likes
Honestly with how well made this video is he might actually be a teacher
* This jideo just tells that the difference between games that good team understand sacrifice of support, and when will the other don't then be dead. ( From League of Legends ) *
Not really
Lol, you're probably right
Yeah but he can make the content before teaching
Reminder: The idea that 'a gene' can map to a 'behavior' as nebulous and one dimensional as 'sacrificing' (or any other term) is essentially impossible. It's impossible not just because we don't understand biology fully or neuropsychology, it's impossible because we have extremely poor frameworks for even describing behavior at a macro level that are internally consistent. This is a fun concept, but don't take it too seriously, as we can't apply this to reality and still claim to know what we're talking about.
There's so much unsettling things in my mind when the music stops and the simulation ends in 14:20
despite having like 30 videos, this man has so many people already here for 20 minutes
😂 he has almost half a million subscribers from 30~ videos
I say that's a decent measure of quality
You know, i understand that this channel is all about showing the estimated values of certain events and all, but the only questions i’d want answered are how big are blobs compared to human size, what noises do blobs make and most importantly, can i pet a blob?
Other than that, a really well made channel all together. But seriously, can i pet a blob, they’ve freaking adorable.
There are plush blobs. So yes, you can pet them.
They are venomous. Touching them might kill you.
Ah yes, the 2 sides of UA-cam
@@baconwizard Agreed.
Blobs feel like velvet. They smell like roses and they sound LIKE THE DEVIL HOWLING INTO YOUR SOUL!!!
You're great at explaining complex terms. When I start your video in the middle I completely don't know what you're talking about. But when I start at the beginning and listen closely it's sooo easy to follow.
When the puddle goes to a tree and seeing how they're siblings and have the same genetics. Wouldn't they all yell to save each other? Killing them all?
It was stated during the first simulation involving predators that only one blob notices the predator, so only one blob actually yells or flees, depending on it's gene, and the other two live or die no matter their gene
I assumed that one would yell first.
It might even result in the 3 of them confusing the predator, resulting in all 3 being able to escape.
@@TheAruruu YES!!! That would be interesting, Primer needs to introduce predator confusion.
@@ARandomSpace And/or a gene that attempts to fight predators, with a probability to win.
Primer uploads: Click immediately, like before watching.
Those are the rules.
Yup, that was my reaction.
Seeing a new Primer video in my sub box is the best thing to happen to me in months! It's always worth the wait 😄 thanks for the amazing, mind boggling content!

4:06 "It's usually a good idea to gamble"
Thank you.
The timestamp should be 4:03.
Another two factors you could look at:
Altruists being more likely to be taken advantage of. They would be more likely to find a predator, because they go to the tree first.
Cowards being less likely to find a partner due to them being less appealing in terms of safety.
Do you mean the altruists would go to trees first, then others would go to trees that didn't have predators?
@@LabGecko Yes. Like how penguins wait for one to jump in the water first to see if they get eaten.
Also, a 3rd extra... if all three possible prey blobs, are altruists. They would eliminate the predator. And all three would go back.
@@LabGecko yes, kinda like Squid Game's glass jumping challenge.. (or Fall Guys door minigame) where letting those who jump in head first fall is an advantage to those that follow afterwards
Alan, why would an altruist go to the tree first? Do you know what the word altruist means by chance?
This was really well executed and explained! I did figure out beforehand the alleles would be evenly matched, but my explanation for it was kind of off and your explanation was much clearer, with the "not identical by descent" chance not having an effect. It made sense after thinking about it for a couple of minutes. Interesting how a somewhat complicated set of variables condenses into such a tidy rule.
Why i like primer :

-BLOBS THEYRE SO FRICKING CUUUTE!
"I think we could both need a break"
No, honestly, I only grave more of your deliecious content!
I could listen to you for hours whith no pause...
and frankly I am really upset that they didn't clarify the loose end of relatedness. Why the heck does the same allele happening not matter just because it came from a different parent. They're in the same value search of increase population. What is the issue with including them? That generations point wasn't thoroughly enough explained.
No, Primer, you don't understand! You may collapse from exhaustion, but that's a sacrifice we're willing to make! /S
