Season 1

Explains how both conflict and cooperation have helped shape the species that today populate our world. And it profiles the winners and losers - from the massive dinosaurs to the humble bacteria that have survived for billions of years.

Take a passionate look at the evolution of sex, which allows a species to pass its genes along from generation to generation.

As predators became better hunters, their prey also evolved better defenses. The drive to survive has produced remarkable hunting strategies. Other animals have taken to deception.

Take a close look at the alliances that animals have forged - with others of their own kind and very different organisms - in a bid to stay alive.

Explore the evolution of brains. The bundle of nerve cells that allows us to sense our surroundings, sort out information, and make decisions.

Explore the factors that make winners and losers in the game of life, and poses the question: who will triumph in the long run?
