Dragons make sense to me. Dinosaurs, obviously, look like huge lizards. However, their spine bones have holes in them just like bird bones do. Birds have lighter bones to help them fly (and also happen to descend from dinosaurs....), And dinosaurs have partially hollowed bones to help them carry their own massive weight more easily. So the fossils would have looked like huge lizards, with bones fit for flight. Ergo, dragons.

If accurate the technique dates the common ancestor for the test organisms only and therefore sets a *minimum* time. One might conceivably find 'less related' subjects that push the date back further. More, if the ultimate common ancestor lead to very early lineages that are now entirely extinct one would forever underestimate the origin of eukaryotes.

Interestingly the Global Oxygenation Event (GOE), like the Cryogene, involved glaciation, and in the late Archaen may have led to prokaryotic multicellularity in cyanochloranta (bluegreen algae or bacteria) with the origin of heterocysts (cell differentiation in cyanochloranta) maybe at around 2.3 Ga (billion years ago), as well as to the origin or expansion of eukayotes; the Cryogene you mention was the prelude to the Ediacarian or last period of the Proterozoic and Precambrian, when complex multicellularity evidently developed (at around 0.635-0.541 Ga). So I see a certain connection. As a fan of simple multicellularity, I was very excited by the news of Bicellum Brasieri -- this is a beautiful documentary!

This just keeps better and better. As always, great narration and images, along with a soundtrack that enhances the viewing experience. Keep up the great work! I originally came to this channel from a recommendation and am so glad I did! I'm also glad to see that you've mentioned Charles Dolittle Wolcott of Burgess Shale fame. He was amazing, especially since he was basically self-educated. He certainly had a great life of discovery.

I haven't commented in years, but oh my god this is an incredible video. I am genuinely switching my major from business to biology today!

Literally blows my mind how your production quality is higher and your videos are more captivating than big budget documentaries

15:49 - This is the Yellowstone River (not the Colorado), flowing though the Grand Canyon of the Yellowstone (not the Grand Canyon), in Yellowstone National Park, Wyoming, USA. (even so, I've been enjoying your excellent series of videos! :-) )

[@MoviesNQuestion]

honestly, keep making these videos, very informative and best on youtube, plus the engaging voice-over, both of your channels history of universe and earth are of top-notch quality, and the time to do research on such topics is massive, you just continue, your subscriber will be in millions, I am sure of it.. huge thanks from India

Hell yes. An hour long video and while I'm stuck in traffic

Leila Battison is an elite science communicator. Props to her on this, (and the others) great, slick and well researched project. Adding in the references just proves her commitment to the scientific method and adds immensely to the authenticity of these videos. No other creator compiles with such integrity. (That i know of). You won’t find references on "spark" or "PBS".

This channel never fails to impress me. Great job, as always.

[@Rafaga777]

I just want to take the time to thank you for the time and quality that you put into those FREE educational videos. Thank you for helping me find a new passion; marine biology.

Fantastic to see Lynn Margulis being given the credit she so richly deserves.

[@Evolved_Skeptic]

Absolutely.

[@rosesacks7430]

I like how videos and visuals are included in your lecture. I watch your lectures multiple times. 👏

"the bones- or stones- they left behind" this had me rolling

[@andreybogoslowsky]

From the beginning of my painting adventure in high school, I noticed the closer my painting comes to completion the more baffled I am by making decisions, and it slows down the process, ultimately bringing it to impossibility of action. It’s a very interesting state of the mind, when after a few months “torturing” this painting, changing many elements and moving things around it appears fine, but it’s sort of disagreeable with everything you know about what painting should be. From the outside it can be described as -“you have exceeded your own limitations and created something beyond your own expectations, and that is good”. But it’s a very difficult state of the mind to know when to stop painting this artwork.

There is so much to love about the immense work you present here! The masterful use of the English language by the writer and presenter stands as a mark of excellence, in a time when the language is diminished by ignorance and laziness, and clearly elucidates the subject matter.

[@davidcraig1714]

This series is of one of the best to find on KZbin, and so being, is the opposite of mind numbing fares that make up the bulk of this entertainment venue. So glad I've find this series! Does this nourish your brain as well?

[@whirledpeas3477]

Just came to read the silly science deniers comments, Always entertaining. I could have gotten more likes from the community and said, Thanks for this wonderful upload!

[@Emdee5632]

And there are lots of uneducated deniers comments here...

[@lordarthur2165]

I thought I was the only one that did that lol Those people make me sad but at the same time I get the great feeling of "I am stupid, but, God, I could be worse"

[@brianfromtheambar7944]

Well done. I enjoy the open-ended content suggesting intentional vacant seats reserved for the promise of upgraded information, and the potential of new discovery.
