The Evolution of Squid
Вставка
- Опубліковано 26 сер 2020
- Molluscs are usually the simplest of creatures often not having blood vessels, sometimes even lacking a proper brain. But one group of animals challenges this, Squid and their other Cephalopod cousins, cuttlefish and octopus. Surviving multiple mass extinctions bouncing through the turmoil of the planets changing environments the cephlapods were shaped and warped from an often simple group of creatures into very advanced forms. Some incredibly alien to us like their multiple brains and limbs, while others were convergent evolution like their closed circulatory systems and camera style eyes. But always with a twist reminding us how distantly related these creatures are from us. Their story is the evolution of molluscs turning into super molluscs.

When he talked about cephalopods moving deeper to avoid conflict with fish, it came to my mind that some of them have evolved into the biggest invertebrates, only to be eaten by sperm whales - which are themselves an oddball for mammals, evolved from fish, returning to the ocean with a lot of detours.
You’d be surprised how often stuff like this happened in prehistory. Mammals evolved and lived in the shadows of dinosaurs and took over the planet after mass extinction wiped them out. However mammal ancestors called synapsids ruled the world before the dinosaurs and the dinos only took over after a mass extinction killed most of the synapsids
Go, mammals!
Sperm whales didn't evolve from fish, at least not directly.
@@prestigev6131 maybe when we die off birds will rule again

I find it remarkable that Argonauts (a kind of octopus) make a brood nest out of a material that they secrete that bears a striking resemblance to the coiled shells of the nautilus and ammonites despite being made from completely different processes. It's like they wish they still had shells.
Thats really interesting, evolution has weird turns of events haha. In fact, after losing their shell octopus got smart enough to grab shells from other animals like clams and use them as portable shells. That use of tools shows how smart this animals really are.
it's called convergent evolution
@@28_ranggaclio Is it though? If it was convergent evolution they would be making a legitimate shell and not some disposable brood chamber. Maybe convergent in appearance only but not really in function.
@@1TakoyakiStore hmmm, yeah. Maybe still ongoing evolution?
@@28_ranggaclio I honestly don't know what it would be called? It would be like if humans lost their eyes through evolution but then millions of years later they had skin patches on the face that resembled painted on eyes. Useless as eyes but in an oddly similar place and appearance.

And as we all know HP Lovecraft compared Africans to squids
So take that as you will since this was right after WW1.
Lovecraft was a product of his age and place (as are most people) - Anglo-Saxon New England in the late 1800s and early 1900s.
You can't expect him to think like a 21st Century American.
I think he was more xenophobic than racist and it shows in his stories.
He was accused of anti-Semitism but his wife was Jewish. But since racism is illogical, you can't expect racists to think logically on that subject.
Despite all that he was a master of early science fiction and picturesque and descriptive English. I love reading his works

Wait snails THEY ALREADY SECRETLY HAVE
@I say the Truth D':
I think squids are a great argument for the existence of intelligent aliens.
Like, if both snails and rats can become that smart in wildly different ways, who's to say aliens didnt do it as well
Well we'll never know.
Cephalopods basically ARE intelligent aliens.
Well they are a long way from human level intelligence it took 400 million years to have the first civilisation so it's not that easy
@@florix7889 Not to mention that even if there have been intelligent civilizations on other planets, if they've developed millions of years apart from humans, what's to say they haven't already died off by the time humans discover their planet or their entire planet have been swallowed by a star or similar?
Intelligence needs collaboration, creativity, construction, and communication in order to form a civilization, as well as the idea and urge to make one. Octopi sort of follow some of these, but to a small level, hence why they don't have tribes. Plus they are hyper aggressive. Besides, it's mainly octopi that show intense brain features. There definitely is some sort of aliens out there with groups behaving like societies, but still not much in majority. If we want to collect messages from them as well, we'll need them to use similar radio technology as us, making another barrier to us talking to them. This is just my take on this. It could be changed by you guy's opinions. Also, it would be cool to uplift octopi into intelligence.
Mollusca is probably my favorite phylum of organisms. Incredible adaptability and intelligence, packaged together with a very short lifespan. The core layer of organisms that will most likely survive any extinction event in some for or another.
Imagine if octopus could live to be 78 years old like humans. What would they look like and how would they act? Makes you wonder how each phylum would look like had they been chosen by evolution to perpetually evolve.
There really is no end to how much mollusks amaze me. They truly are the most fascinating creatures that I have ever stumbled across.
How could you not mention ammonites 😱 they're more closely related to modern shelless cephalopods than to nautili
I think that will be an topic for another day.
Andrew Gan hopefully yes
ammonites are so rare that we don't really have a lot of information on them
@@elliot_rat the whole animal that is. the shells on other hand were very common. so common they often use them as index fossils alongside trilobites.
@@ItsEthanDude ammonites were an wholly different family of cephalopods.
Pretty sure squids and octopus are closer related to things like ammonites than nautilus are.
Nautilus are part of a further off slightly more primitive sub-family .
The man also referred to the horseshoe crap as a relative.
Yes. Squids, octopuses, cuttlefish, and ammonites are grouped together as Coleoids, while nautiloids are completely different.
@@jerk5959 Horseshoe crap

ALL HAIL THE GNOME KING!
pretty good as always. just a few corrections: horseshoe crabs (Ecdysyzoa) and cephalopods (Lophotrochozoa) are not close relatives, and the majority of squid locomotion is achieved via jetting water through their siphons, as opposed to beating their fins.
I wonder if animals with multiple brains can feel lonely.
Or get along with themselves?

Interesting, snails, my freshwater snails can either float up or down to the bottom only. They cannot maintain floating without refilling their shells with air once they surface. Some can glide mid-water with the help of mucus, however.
You might enjoy zefrank1 and his video on snails. Also peacock spiders, ostriches, bobbit worms, others. Lots of true facts.
@@veralenora7368 That surfing snail was really unique.
They'll eventually evolve into Cephalopod-like creatures in the distant future, plus they have 4 tentacles that resemble cephalopods.

i'm not joking, chicken works incredibly well when trying to trap nautiluses
How do you prevent the chicken from drowning?
And can it actually dive deep enough to catch the nautilus?

I always found it fascinating and weird that cephalopods have so many traditionally vertebrate traits despite our last common ancestor with them having none of them. Camera-like eyes, closed circulatory system, up and down opening and closing jaws, highly developed brain. It's so strange finding such a similar set of traits convergently evolve in two otherwise very different groups of animals.
So nice, nature made them twice!... Or more.
I've never thought about this, but this video is what I really needed

Admit it. We all learned the word "cephalopod" from playing Splatoon.
Primordial W O O M Y

Has anyone come up with a good explanation of how/why ammonites evolved to coil up neatly, but then produced loads of weird 'evolute' forms, in various degrees of uncoiling, and even opening out into three dimensions of of separated coils? Were they trying to gain more surface area to aid cooling, perhaps?
Used to be straight then...
B O N K
I usually chock stupid body designs up to chase away theory. My guess is it differentiated mating.
3 dimensions that we know of. :)
Thats not how evolution works... There is no "trying to". Its by natural selection, not design. Whatever variation occurs is selected from - those that work live, the ones that dont, die.
How the variation occurs is related to how the shell is formed. A small, but consistent skew in growing the shell will result in coiling, the extent of which can be both two- or three-dimensional.
The weird shapes made vertical diving easier and more energy-efficient.
Horseshoe crabs are arthropods. While they do use hemocyanin like the cephalopods, they are only extremely distantly related to molluscs, being in separate phyla. In other words, there is as much genetic distance between arthropods and molluscs as there is between molluscs and humans, possibly even more. Because of this, the fact that some molluscs and some arthropods use hemocyanin is likely a case of convergence.
Then they turned into kids who are allergic to water and can turn into a squid that swims in ink.
But they do have some really good music
their music taste was fire though
Genome sequencing would be a great tool to uncover if cephalopods are related to these limpet-like creatures and perhaps could resolve which of these species groups they evolved from.
You mean phylogenetics? The ancestors are long extinct and wouldn't have intact DNA, so genomics wouldn't help with that side of things.
There is a new method which used the remaining proteins to get a guess how the DNA may lokked like. Because DNA starts to decay after ~ 1,5 million jears. Proteins last way longer.
@@molybdaen11 Don't proteins also have a half-life of less than a million years?
@@stefanalexanderlungu1503depends on the protein keratin is in feathers and those have been found over 60 million ago the biggest problem with this if we don't understand how DNA influence traits yet.
I wasn't sober upon reading the title, and foolishly thought it was a long-awaited video on The Evolution of Stupid.
After millions of years of evolution stupid still exists in our species at far too high a rate to be an abnormality, so there must be some evolutionary explanation!
Next video please!
@@wilfdarr hmmm you may be on to something. Stupid people tend to reproduce at higher rates but also their offspring have a change of not being as stupid as their parents so there's a net increase in intelligence over time? I think?
Anyway if enough dumb people have smart kids eventually the smart people will improve society some what, enough for dumb people to reproduce more easily continuing the cycle?
Lemme know if I'm wrong somewhere here with this idea
@@iamrazor9831 Biologically I have no problem with it. Politically, it implies that authoritarianism is inevitable, the intelligent outliers necessarily leading the stupid majority. It would certainly explain some things... 😔
@@wilfdarr the explanation is that natural selection doesn't apply to developed societies due to medicine and technology removing the need for finely tuned genetics over the course of centuries to millennia.
@@benderisgreat95able I disagree: that's like saying ants don't evolve because they tend to their wounded and work as a hive. But hives that work better will out perform hives that don't, for both social AND biological reasons. Medicine etc certainly slows this process, but especially once you consider the constant waring up to the 20th century, I don't believe you're argument valid since societies that out perform other societies will force the underperforming societies into extinction. That isn't to say that this argument couldn't be valid going forward with globalization, I just don't believe it valid up to the present. And the evolution of a pseudo hive is I believe exactly what I AM RAZOR was talking about.
Great video! You made me research a bunch of stuff out of curiosity, like how nautilus live, they are basically dumb scavenging floating snails that can barely swim, breed and grow slowly, almost the total opposite of other cephalopods. Makes sense how they survived the mass extinctions but not sure how they are not the perfect snack for other predators.
Cephalopods are very fascinating, the way they have evolved from a completely different evolutionary tree of very passive and simple creations into an intelligent predator. Thank you for the content!
P.S. I was here before 100 thousand subscribers)
I wanna see someone create a movie/game based on a version of earth where cephalopod based organisms were the ones that pioneered to live out of the water and then dominate the land and air. That would be so cool.
There is actually a game, Splatoon
It takes places 12k years in the future where all mammals go extinct and sea animals evolve to go on land and obtain a humanoid form, while the main creatures are Inklings and Octolings. Inklings evolve from squid and Octolings evolve from octopi. Only in the second game are you able to play as an octoling though, with a DLC called Octo Expansion, where you're an octoling trying to escape from deep underground to the Promised Land (aka the surface)
I feel like I've rambled on about the game bit too much now haha, sorry about that

@@agenthellothere Don't forget the bear who employs Inklings/octolings to hunt salmon in order to achieve his goal of returning mammals to the planet.
@@justsayori3046 you fr made me look at a 2 year old comment of me missing a joke to understand the context of what you were replying to
One of the channels I'll gladly watch ads for!
Thanks for this great video. I fell into your site chasing another thread and am super glad I did. I have to agree with a few of the comments here about ammonites vs. squid vs. nautilus. I am looking up at a cut and polished fossil ammonite, (2 halves of the same animal), I have on a shelf above my desk. It is about 6" across and the divisions picked up copper while the spaces filled with agate. It is incredibly beautiful but I mention it because at first glance it looks much more like a nautilus with the divisions getting larger as the animal grew, but many creatures that make segmented shells do this, think whelks, periwinkles, etc. however there aren't any that can float like a nautilus and that must put the nautilus in a family of its own so it does seem that they are further apart in the evolutionary tree from a squid or an octopus and much closer to an ammonite. After all, a nautilus is a very very old creature that found a perfect shape and feeding behavior and decided it was going to stop there and not bother to evolve any further while the other cephalopods went gaily off to invent circulation and eyes and multiple brains.
I feel like squidward and Splatoon fans would like this.
Did I just hear cephalopods have 3 “brains”? I know they have 3 hearts but I am unsure about the brain part. They do have donut shaped brains, where the esophagus travels straight through the space in the middle of the brain.
They don't have three brains. It's more like one brain that isn't just in one place. They also have a huge part of their brain in their tentacles for example.
Octopuses' bodies _are_ their brains
there are also two lobes behind the eyes.
In a similar way, you could argue that our central nervous system is "part of our brain", no?
@@thesuperginge1348 It you separate the cortex, neocortex and cerebellum, it could be argued that humans have 3 brains. If you then subdivide the left and right halves being able to operate independently, connected by information highways like the corpus callossum, it could be said we have six.
Hey man, just wanted to tell you that your videos are incredible, among a lot of 2-3 minute videos of basic and sometimes incorrect information about prehistoric animal, your are definitely one of the most complete and interesting, in other words your videos rock!

i love this channel. I found it a few days ago and thanks to it i've rediscovered my passion for paleonthology. Keep it going, you are doing an amazing job!!
“The reason why more cephalapods decided to coil their shells was because coiled shells looked way cooler to them”
I find amazing the independent development of eyes in different species.
Evolution is astoundingly beautiful.
the differences between our eyes are also very interesting. We use color sensing cells to see colors for example.
Cephaopods use their pupil shape to different between different colors (with refraction).
Thats why the pupil shape of cuttlefish, and octopuses to a lesser extend, is so weird
@@aldoushuxley5953 and they evolved the sensor cells with the proper orientation so they don't have a blind spot
Limpet ancestors had coiled shells like other snails which secondarily became flat. Some limpets even have an atavistic swirl at the top.
Discovered your channel recently and I'm really enjoying it. It's bite sized yet detailed zoology that I think anyone who doesn't understand evolution should watch. When you focus in on particular orders / families you can see how it all happened, the branching of lineages makes sense, that's even before you add the insurmountable genetic evidence.
Keep up the good work!
bro this mans voice is so comforting I'm boutta fall asleep
I love these videos, your content is of unbelievably high quality. You deserve many more subscribers. Keep it up.
I always wonder how a creature would look if it was completely outside of every category of lifeforms we actually have, it intrigues me to imagine a creature evolving to be a completely new concept of life we never saw before, like, how would it's skin look? Would it be bumpy? Would it ever evolve fur? How would it's eyes look? Would it even have eyes? How would it swim? And something that intrigues me even more is to imagine how that creature would evolve in a planet like ours when life was just starting
Fascinating video that was really well done. Keep it up!
These digestible and interesting videos that explain evolution and how we get the species that we have today is really important since there are still many who don't have even a basic understanding of how in depth this evolutionary process has been studied and just what it means for explaining the world around us as well as ourselves!
I just spent a couple of hours watching your videos and, though I like in-depth learning, I have to say I truly enjoyed learning the snippets of info you provide. The problem with most documentaries is they are kind of stuck at the high school level. They leave out a lot. So by watching your videos I'm catching bits of information such things don't provide. You have a very happy new subscriber.
This is an awesome display of how frequently convergent evolution can occur even in different environments! Awesome!

I thought i had heard it the other way around, that limpets actually evolved FROM snails, and occasionally show a small amount of shell coiling.
Limpets are actually a snail with primitive organs compared to Caenogastropods and Pulmanotes which have a more advanced central nervous system.
