It’s one of the most important developments in the history of life. An adaptation that lets animals kill, butcher, and devour. There is perhaps no instrument more important to survival than a strong set of jaws.
From the shark’s rows of razor-sharp serrated teeth, the crocodile’s overwhelmingly swift-snapping-trap, to the lion’s shredding canines–all have evolved in response to the never-ending struggle between predator and prey. But just how did these ultimate killing weapons develop in the first place?
It’s a tough, violent, and lethal world out there, and it’s been that way since the dawn of time. Roughly 99 percent of all species have become extinct. What enabled that other one percent to survive the cutthroat competition?
Their ability to…. EVOLVE.
Through a stunning combination of dramatizations, computer animations, live action nature footage and lab work; discover the biological and behavioural innovations that have kept us all on this Earth!

Did you know that human teeth prove we should be vegetarians. A vegetarian told me this. He has no reason to lie. Then he died from malnourishmen. Derp
I'm glad we humans have big brains because jesus there's so much out there than can kill us.
Rawr goes everything
"But just how did these ultimate killing weapons develop in the first place?" I haven't seen the video yet but I'm assuming the answer is to diversify our food supply. First from herbivore to carnivore and then omnivore. Better survival rate when you have more food choices.
I thought that said Jews lol that was really interesting watching that me and my girl found it interesting but I hated the monotone voice
i gawk at out innovation.
interesting episode, i love sharks
