I had no idea that lungfish were the closest living relative of tetrapods, and that their lungs are homologous to ours. I always thought their lungs were the result of convergent evolution.
Probably are tbh; Lungfish Homoplasy Hypothesis is exactly this. The alternative hypotheses want you to believe you can go from a fully aquatic Lungfish like Eusthenopteron to terrestrial Amphibians in just 10 to 15 million years.
@@Afrologist I'm not sure I follow your reasoning. Any common ancestor with a pouch off the pharynx for air storage fits the bill, and (unless an unequivocal ancestor without this feature is somehow identified) doesn't impose any timing constraints. And in any case, “convergent” evolution often (not always) seems to involve re-emergence and development of earlier strategies. But of course I am not a lungfishologist, and I may have completely missed your point.
@@stephenspackman5573 The mechanism for evolution is random genomic change. Good luck convincing me that an animal was completely able to fundamentally alter almost every major system in its body in the amount of time it took Gorillas & Chimps to diverge.
@@Afrologist Actually it also works with a lot of stored historical data in the DNA, some important multilevel structuring that has evolved to speed up adaptation, and constant selective pressure. Oh, and, critically, _death_ is not random. But it sounds like you're not up for reasoning, so let's leave it there and not alienate the spectators any further.
It's beautiful how you can see the entire evolution of the heart on currently living animals. If possible, I wouldn't mind seeing more videos about the evolution of other organs, senses or specific body parts
@@Nekrumorfiini1 though some (if not most) organisms retain features of the last common ancestor. Like how humans and bacteria are both "equally evolved" but the LUCA was far closer to a bacteria
@@Nekrumorfiini1 while evolution doesn't have a target and is just randomly what happens to work, it also builds off of what already exists, so while it's not like animals were trying over time to make a human heart, the structures that would become the human heart can be found in other animals, the closer you get to humans the more it looks like a human heart. You could put the end point on any animal with a heart and see the same pattern, but humans like talking about themselves a lot.
While watching this video the old Christian chestnut of "how did the heart, such a complex structure that seems incomplete and ineffective without all its constituent parts and aspects, evolve in steps? Surely, this disproves evolution." And here is a short video addressing every concern of that line of questioning lol. Very cool and interesting! Great job.
Evolution of the human brain specifically is a whole can of worms, and it opens up into long arguments about eugenics and ill-regarded 20th century political ideologies.
This is a unique video rather than focusing on an organism or ecosystem we get in depth look at the origin and function of organs Suggestions for future videos 1. Evolution of cats 2. The advantages of different types of reproduction 3. What animal group is best suited for a particular ecosystem
1st one already happened I believe (cats and dogs), 2nd would be nice, but 3rd is a bad idea as there is no such thing as being "the best" in an ecosystem
I think this guy should also go where no paleotuber has gone before - evolution of the boring - the other deomesticated livestock. Chickens, ducks, goats, cows. I'm thinking of raising ducks and I wanted to learn about their evolution. No vids on youtube. Or other common animals, what's the evolutionary story of the animals we live with? Squirrels, chipmunks, deer?
This is such an amazing video, I love it so much. There were so many bells going off in my brain saying "so THAT'S how that's works" throughout the video. Simply great
You skipped something cool - four chambered hearts may be better for an active lifestyle, but three chambered hearts are better for animals that hold their breath underwater because they can make the body circuit a closed loop.
Which eye. There are 3 completely different types of eye, and multiple variations in 2 of them. There's a book about this, but i forget the title of it.
If you're looking for suggestions on other video topics I think digestive system would be really cool. Bring in ideas of how its on the outside of our body and how it came from radial symetry etc. Regardless i love the vids
Suddenly a lot of my fragmented information from Wikipedia-surfing gets connected and makes sense - through a short, pedagogic AND aesthetically pleasing video. It's channels like this that makes UA-cam worthwhile.
If anyone was thinking, "if insects are size-limited by their open circulatory system, how'd they get big during the carboniferous?" There was a crap ton more oxygen readily available in the air back then.
Yes it's because the devs realized that by opening the land servers to everyone was going to be a bad idea if there wasn't enough XP sources for everyone. So they decided to add a crap ton of trees. However this increase the oxygen concentration in the atmosphere thus the arthropried mains had a higher size limit. For example: there was a millipede type build roughly the size of a small car.
So that must mean that birds and mammals evolved 4 chambered hearts independently, right? Are they different from each other? Also, this is a great idea for a series! It would be cool to see the evolution of things like eyes, ears, different kinds of feet, etc.
They have different arrangements of the aortic arches. Crocs have the same 4-chambered hearts as birds, but a valve allowing them to mix the blood like basal amniotes.
@@jackslater5886 not possible, birds and crocodilians have much more in common with turtles and lizards than with mammals. It's more likely that a 4 chambered heart evolved separately in archosaurs and synapsids.
@@astrowyrm6871 to put things very broadly: cold blooded vertebrates have two or three chambered hearts and warm blooded vertebrates have four chambered hearts. Crocodilians had ancestors that were warm blooded, in fact, the lineage that would eventually lead to crocodilians were warm blooded up until very recently, but said lineage eventually had evolutionary pressure to become aquatic ambush predators, a lifestyle that favors being cold-blooded, which required their hearts to act like a three chambered heart. How this was achieved is by having veins that led from the ventricles to the rest of the body mix the oxygenated and deoxygenated blood together. Crocodilians, can, however, have their heart act like a four chambered heart again in the presence of adrenaline which closes off the veins, causing the oxygenated and deoxygenated blood to be separate from each other. Fun fact: the only reason why crocodilians didn't die out from the asteroid when the non-avian dinosaurs did is because they were cold blooded. It just goes to show that warm-bloodedness isn't inherently superior to cold-bloodedness, evolutionarily speaking.
@@lithobreak3812 I don't fully understand it either, but I think it reduces how much oxygen the body consumes, which allows the the organism to go on "low power mode" without any further modification. But just to make clear: this is just a guess rather than definitive fact.

Indeed it can be, that said there's more homology in the most commonly treated patients after all. You know your dog's, cats , horses, pigs, rabbits, rats all placental mammals with relatively recent common ancestry. Many systems are very similar aside from size and rate of growth, for example as this video alludes to the heart, the orientation of the vessels and the size of the heart is the only thing that varies in these animals that I know of through my studies trying to get into this field. Mostly ditto for things like the lungs bone forming tissues and more. Obviously parts of their anatomy, more conductive to their differences in lifestyle such as their jaws, digestive systems, reproductive systems (they may all be placental mammals but this can still vary more than one might think.)and limbs are far more variable but the kinds of Bones these are made out of or at least homologous. Which is to say, most of the extreme cases would call for you to have extra specialist training anyway. A dog is far more similar to a pig and a pig to you and a horse to a pig than a cuttlefish will ever be internally. And indeed there are some train to do some exotic things with such species, but being as in becoming doesn't necessitate such to my understanding. I hope that was helpful!

What about the blood ark clam? It's unusual in that, despite it's relatives having copper based blood (hemocyanin) it is an invertebrate that has iron based blood (hemoglobin).
