Since the dawn of time, roughly 99 percent of all species have become extinct. In order to survive, all creatures, including man, must treat life as a battlefield and master the natural weapons and defences that they have evolved: Tyrannosaurus Rex's 13-inch canines; the gecko’s Velcro-like toe pads; the bald eagle’s telescopic vision capable of spotting a hare a mile away.
How did these attributes, each unique to the organism itself, appear? Certainly not arbitrarily. They evolved for a common reason - to give these animals a critical edge in interspecies warfare, and to ensure the survival of the individual’s genes into the next generation. To evolve is to survive.
It doesn't just take willpower to survive. It takes guts, in the form of a digestive system that turns food into fuel. We look closely at the role guts have played in shaping some of Earth's most successful animals: tyrannosaurs, snakes, cows, humans and others.
We 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.
