- Turtle evolution has caused many problems for scientists over the years due to multiple fossil discoveries seeming to contradict each other with different turtle features evolving independently on different turtle ancestors. However, although there is still work to be done this video sets out to explain what is known so far.

the next stage of turtle evolution is developing water cannons on their backs
Not quite. They still need to evolve sunglasses.
they still need to learn how to stand up

Fun fact, Turtles and tortoises have nerve endings in the shell. Its apart of the skeleton. that means they can feel you scratching them. And that means they can feel pain when damaged or miss cared for. So yeah, you can pet a turtle.
THE PEOPLE MUST KNOW. YOU CAN PET TOITLE.
It’s true! My turtle always hated when I scrubbed the algae off his shell
Most don't like any physical interaction though
Yes and if you tap them at the back they get annoyed and move forwards.
they also bite, especially the wild ones
It only makes sense that good diggers would be good swimmers, after all, it's just locomotion through a dense field of a matter. It's such a clear correlation, but I would never have thought of it that way without this channel.
It's interesting that this doesn't work in reverse. Swimmers aren't good diggers or whales would make truly impressive burrows.
Me:*puts a bulldozer in water*
Moles burrow through water quite well after you attach a brick to them.
@@duybear4023 That's because once you go aquatic you become dependant on the buoyancy of the water for support not your limbs so they lose strength and range of motion for things like walking and digging and either disappear or become more streamlined with larger surface area for less drag and better propulsion.
@@duybear4023 that is a terrifying concept
After watching so many videos on convergent evolution over the past month, I am now absolutely convinced that our distant descendants will look like crabs with beaks.
The crab form is the ultimate form.
Isn't that what the enemy looked like in the film Starship Troopers?

@@strzygon5426 I second this what
Great episode. Looking forward to part 2 where I’m sure you’ll cover the Ooze and Master Splinter’s role in their evolution.
LOL
I laughed a little too hard at this
🤣🤣🤣
I always thought it was Splinter, as well but recently found out it's actually Splina'. I chalk it up to the Mandela Effect. Lol
I hate you
Moles and Armadillos are great swimmers? Damn, I’m learning a lot today
Evolution is weird 😂
@@jojak8066 When you think about it their bodies have essentially become boats.
They are such good swimmers they can swim *in the ground!*
Now that i think of it, plenty of fish burrow too
Moles swim through dirt.
My bearded dragon has very wide ribs and is still quite quick at digging in a wiggling swimming motion. He also can expand his ribs in the sun for more surface area for basking. When he does this I call him “sun cookie.”
I think he meant wider as in each rib taking up more space along the spine, not wider as in the ribs spreading out further. So, like, the base of each rib being wider, not a wide torso.
There is no comparison between the ribs of turtles and other animals. Turtle ribs are laterally expanded and don’t curve under the body. This configuration is unknown in every other animal. Bearded dragons still have normal shaped and spaced ribs and can change their shape, move and breath like most lizards.
@@stefanostokatlidis4861 it's kind of tricky to talk about because I'm not sure whether it's proper to define lateral and longitudinal in relation to the spine or to the rib. Relative to the rib, turtle ribs are laterally expanded but not longitudinally. Relative to the spine, Bearded Dragon ribs are laterally expanded but not longitudinally. But of course these identical descriptions are in a frame of reference opposed by 90 degrees.
I just call mine slut dragons no matter what they do.... or a pancake
Sloths also share the burrowing-swimming connection. Even if they haven't done the solid-rock excavation part in a long time, they've still got that swimming technique down.

You should do the evolution of the pufferfish. Their skeletons intrigue me, and I would love to hear your research on the topic.
Tortoises are my favourite animals. I really hope more about their evolution is discovered soon :D
Evolution of species is childish nonsense, only suitable for ignorant beliebers.

2:59: I just want to point out that the theory that turtles are closely related to sauropterygians is *not* exclusive to the possibility that they are lepidosaur relatives. It is entirely possible for both turtles and sauropterygians to be archosaurimorphs based on existing evidence.
I hear this and was immediately confused as clashed with what I was taught at uni! Thanks for clarifying
I hear mixed things about where turtles line up, DNA evidence seems to point to them being related to archosaurs, morphology points them closer to lepidosaurs, and I have heard others say they are related to neither and are outside of the saurian clade as basal diapsids.

@@Dss-bm3rz pretty sure that they’re basically a balloon with legs lol
Based on cartoons and stuff like that you’d expect them to be “in” their shell (able to get out) while in reality the shell is part of them (and the organs hang onto it on the inside if I remember correctly) such a “WAIT WHAT?!?” Moment when you first see it.
My favorite paleo channel, always such high quality content.
I have a pet tortoise so.......
I was obligated to watch this.
Good video:)
if you like listening to lies
@@travisspace7786 when it’s 2021 and you still don’t believe in evolution
@@JJ-mc5vn Yup key words ( believe ) its a religion. USA founded by Christians slowly dyeing to the years of Evolution indoctrination in our public schools. Nazi Germany/Communist Russia and China founded by Evolutionists Marxists who believed they were the supreme race. If evolution was true we are not created equal by a creator merely a bundle of cells that has no true value. Matter of fact some of us would be lesser life forms diluting the "superior species" justifying Hitlers atrocities because if their is no God, there is no moral law. If there is no moral law, right and wrong is relative. So what they did would have been right in their own eyes. But it wasn't it was wrong. Evolution is built on a foundation of Death and lies. Seeing 2021 unfold you would think more people would be turning towards God and lots are. They have plenty of time to learn the truth wile they sit on their butts not working. But lots are willfully ignorant or chose to look for ideas suggesting that God isn't real because if would affect their life style and sexual mores. Christians love science because it has been used to prove Gods existence, don't need it to prove Gods existence but it helps the scoffers. We also haven't lied to support our theories on how the world was created. Would you like some information on why evolution is a lie?
@@JJ-mc5vn sorry man i like the concept of evolution but we're still not sure about it so don’t say for sure, the other guy is wrong tho for completely denying it
The generated closed captions guessed "you know thesaurus" for Eunotosaurus
“Good diggers are also good swimmers” that phrase made my mind *ascend*, it was actually something quite obvious I had never thought about
Sloths with their freeky ass fingers were from underwater
It's also completely false. Most diggers aren't great swimmers - armadillos *can* swim, but only very short distances by gulping air to inflate its intestines to counter the weight of its bony plates. To call that a great swimmer is reaching. Most similarly sized animals do better, don't they? Armadillos also prefer to crawl underwater.
Animals develop or lose the ability to swim depending on how useful it is or whether other abilities it has to give up for it are more useful, it seems. Naked mole-rats that live in dry chalky soil drown when thrown into water, whereas basalt-dwelling animals of the same species (sic!) living only a few meters, up to a few hundred meters away (sic!) away can swim.
There's little to support the hypothesis that “good diggers are also good swimmers”.
@@Muenni That’s pretty interesting, thanks for the info, I’ll research some more into this though to see if there’s any more things that support or deny the statement

Ey good one
The uromastyx is a good example of an extant genus with wide, flattened bodies.
But it has no flattened ribs and they still curb at their end. Uromastix are convergent with procolophonids.
you're quickly becoming one of my fav content creators. I think I've watched all your videos twice now haha
Same this is my second video on this channel
I've been looking forward this very specific video for a time, love your work man.
If you wanted to know a long time ago why didn't you do your own research?
@@chevychase3103 I meant from this specific (get it?) channel, mostly as praise, and yeah I did investigate, don't worry. The real question is, what kind of person goes out of his way to publicly admonish a random youtube user for his supposed poor investigative efforts, when he's merely, clearly, making a supportive statement?
I'd love to see one on the evolution of the various birds of prey. Or toucans.
You made my that. Could you consider one on stegosaurus and it's family?
Last time I was this early turtles didn’t have shells
I have a shell
I have no shell
Im not a turtle
I’ve been following for a while now, it’s awesome to see the increase in quality over time. Such a gem of a channel
Have you visited mario lanzas paleo on youtube? His channel is great too.
Just now finding your channel. I very much enjoyed this video! I will be subscribing and considering the patreon thing as well. Please keep up the amazing and informative content!
And here I am cuddling my pet Red Eared Slider...
I’d be lying if I didn’t admit that bones on the outside makes a lot of sense.
I been wondering and researching about the evolution of turtles for years. Thank you.
I really appreciate the cohesion of the script, it all fit very well making very easy to follow, thanks
Would yo do a video about the evolution of ratites? You're very informative
stem turtles: experimenting by trial and error. as if trying out which works and which didn't cause we got shell-less turtles with no teeth and we got half shelled turtles with teeth.
I just found your channel and instantly subscribed, I love content like this.
I've recently found your channel, and comparing this video to the synthesis paper I wrote for my paleo class was really enjoyable.
I REALLY want moth light media to cover the strange ecosystems of Ark, and how the various ecosystems strive together.
Can you please make a video on the evolution of cells? Like how prokaryotic and eukaryotic separated and then how eukaryotic organisms evolved specialized cells like skin, muscle, nerve, bone, stomach, eyes, etc. Itd be aamazing
THIS!..
Oh, that time an archea got eaten by a bacteria and refused to be digested...
Best growing channel.
I don't know how interesting a video on squirrels would be.
Im glad this came upin my recommendations, just subbed, great content!!!
Can we please differentiate between tortoise and turtles please.
The absence of DNA to prove these lineages makes them little more than guesswork. AKA "This looks kinda like this, and kinda like this "
Guessing about the nature of things is all we have without actual DNA, but that's no reason not to guess. If we are unable to understand something, guess-work is infinitely more valuable than not trying to understand it all.
Also guesswork: who your real dad is
Even with the absence of DNA, there's still a lot of things we can infer from fossils alone.
The thing is turtles might be basal reptiles outside of saurians, so it wouldn't be more related to lepidosaurs or archosaurs. Depending on which method, turtles have been found either related more to lepidosaurs or archosaurs ,though more evidence leans towards archosaurs though turtles morphology matches more with lepidosaurs and some parareptiles (which could be a paraphyletic grouping, with some like mesosaurs and bolosaurs being basal sauropsids, and others pareiaosaurs being diapsids closely related to turtles)
Amazing video! It certainly makes sense that multiple species evolved similar adaptations. It is crazy to think a tortoise ancestor went from land and having clawed feet, to having fins and a shell, then back to land and clawed feet. There must be an aquatic ancestor that was more like freshwater turtles with webbed toes. I can't wait for more discoveries
Great vid again, thanx! The evolution of the turtle is by far the most intriguing and complicated gap=filled puzzle in all species evolution I think. One just has to witness the complexity of the species in real life, and its mind starts boggling right away!
Brilliant👏
One of the many proofs of Evolution👏👏
ok,now talk about how one of them evolved to carry the Earth on its back
Thank you for your great video with interesting information and great sounddesign
Awesome video as always.
I would love to see a video on birds from the period just before to just after the kpg extinction event (couple of mya). I am very interested in what types there were before, why certain groups made it and how they radiated after the extinction.
I know there are videos on this subject more focussing on certain species or families etc, but I would love to see sort of an overview.
*I Like Turtles*

Peace to you and thank you for the videos
Thank you for incuding photos of fossil skeletons! It's very interesting
"I like tewtles!"
You never mention tortoises, I find this confusing to me turtles are aquatic and tortoises land dwelling but are all Chelonians
Turtle also refers to all testudines. Which includes all turtles and tortoises. It is a synonym of chelonians
Tortoises are also much more recent and evolved from aquatic turtles.
Turtois is just a type of turtle, that or turtle has no scientific meaning and is paraphyletic.
Love the videos. Always learn interesting stuff

And yes, turtles used to have no shell attached to their spinal cord as a bony shell to protect them, and looked like big long lizard things befor ethe age of the dinosaurs before turtles started evolving.

2:40. Hold on... modern DNA studies suggest it is highly unlikely that turtles were anapsids?
What DNA was compared? The reptiles in question were eliminated in the Great Dying, over 200 million years ago.
It's mostly out of DNA and anatomical mixture. The DNA evidence pinpoints turtles as being almost the branch with archosaurs, such close relationship would refute the anapsid hypothesis.
