Evolve
S01E02: Guts
It doesn't just take willpower to survive. It takes guts--in the form of a digestive system that turns food into fuel. Look closely at the role guts have played in shaping some of Earth's most successful animals: tyrannosaurs, snakes, cows, humans and others. Take a 575-million year journey that begins with the planet's first multi-cellular organisms and ends at our dinner tables. Watch as live-action natural history sequences, CGI, epic docudrama, and experimental science help to illustrate our and our fellow species' eternal struggle for survival on earth.
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.
