Evolve
S01E03: Jaws
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?
Overview
Evolve is a 2008 documentary television series on History. The series premiere, "Eyes", was nominated for an Emmy for Outstanding Science, Technology and Nature Programming.
Each episode attempts to explain the evolutionary origins of a particular trait of living creatures: for example, Tyrannosaurus Rex's 13-inch teeth, the gecko's "Velcro-like" toe pads, and the bald eagle's "telescopic" vision capable of spotting a hare a mile away.
