Tenacious DNA

There are a couple minor things I have issues with in this compilation, but it's a very moving piece of work. Definitely worth 12 minutes of your time!

My only issues with the film are that first, the text for the Cretaceous-Tertiary Extinction is confusing. It seems to say that surviving avian dinosaurs later evolved into birds, then mammals. I think the point was supposed to be that avian dinosaurs and mammals survived and that birds would later evolve from the avian dinosaurs.

Secondly, not that life was easy for early hominids by any means, but the depiction of an individual taking on dangerous game on his own doesn't sit well with our evolutionary math. Our intellect and sense of community were much more likely drivers for survival than strength and bravery. A theory that fits into this realization is Persistence Hunting, another interesting topic I'll be learning more about when I can find the time.
