  • Check out ReInventors: https://www.youtube.com/channel/UCzZR...Experts are still arguing over whether Archaeopteryx was a true bird, or a paravian dinosaur, or some other kind of dino. But regardless of what side you’re on, how did this fascinating, bird-like animal relate to today’s birds? It turns out its teeth were a clue that this story goes all the way back to what we now call the non-avian dinosaurs.Thanks to Ceri Thomas for the excellent Longipteryx reconstruction.

    the fact that a hummingbird is a highly derived dinosaur that has adapted to the ecological role of a pollinating insect is just mind blowing

    Ever been bitten by a Goose? They have teeth. Yes I know they are technically called tomia and are not true teeth. But functionally they are teeth... and they hurt.

    I'd love a video on the evolution of endothermic (warm blooded) animals, for example when did the switch from cold blooded reptiles to endothermic avians happen? Were any of the aquatic reptiles like ichthyosaurs endothermic or were they all ectotherms? Additionally if there is any information about the earliest endotherms out there?

    This is literally the best channel on youtube. No gimmicks, no wacky personalities, no non-sense; just a normal, straightforward narrative that's clear, concise and succinct.
    You have no idea how happy the existence of this channel, and the people behind it, makes me.

    Evolution says "lets drop these teeth to save weight", nature says "but you need a way to grind up food". Evolution's answer:, "its ok i will just eat several rocks. Saves weight you see".

    Didn't scientists in the US genetically modify a chicken embryo to get it to grow teeth?

    Lately iv found it amusing to inform people that birds are actually dinosaurs because apparently most people don't know and I like their reactions

    Here's a video topic idea. The history of paleontology itself. Old ideas we used to have about fossils, how and when we figured out that fossils are the remains of long extinct creatures and not undiscovered ones, how we figured out the story of evolution long before we even knew that DNA is a thing, etc. If I'm not mistaken, the ancient greeks occasionally found fossils of large animals, which is probably how they came up with giant mythical creatures. And native americans are known to have collected small trilobite fossils and called them "little water bugs" I think.

    You should do a segment on 'Haaste's Eagle' . There is very little material about that super raptor out there. Normally people always talk about the Moa and forget all about the poor extinct eagle. It died out not so long ago and our own modern people lived in great proximity with them. Imagine actually seeing that monster flying up in the sky. The fear of the indigenous people. Like a jet plane. Scary. You must recreate this beauty.

    I was hoping you guys might cover the transition from an aquatic world to world with terrestrial animals. I always hear the phrase "when creatures first stepped on land" but I don't really understand the details.
    I love the show! Keep up the amazing work!

    Interesting topic. Looking forward to learning about it.
    If I may suggest a future topic, perhaps a video on how metamorphosis evolved in insects mostly, but also frogs and such. I think that and s video on things like gorgknopsis or kaprosuchus would be awesome to learn about.
    Keep up the incredible work eons team😄👍

    "Scientists have found that the last common ancestors of all living birbs was indeed a grounddwelling seedeater".
    I do love me some toothless grounddwelling seedeating birbs.
