Throughout eons of evolution, the natural world has played host to this never-ending competition. Since the dawn of time roughly ninety-nine 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 defenses that have evolved: Tyrannosaurus Rex's 13-inch canines; the gecko's Velcro-like toe pads; the bald eagle's telescopic vision that is capable of spotting a hare a mile away. What is the history of these evolutions and how did they come about? They didn't just appear arbitrarily, they evolved for a common reason - to give these animals a critical edge in interspecies warfare. To evolve is to conquer!

In the history of life on earth, sex is the ultimate survival skill, as the bottom line is reproduce or die. This driving force of life comes in many forms. How will sex evolve in the future?
The pterosaur began flying over 220 million years ago and evolved to be the size of small airplanes. Scientists examine fossil records and living birds to learn how some species learnt to fly.
From the delicate membranes that encased the earliest animals to the leathery hides that protected dinosaurs, how skin has changed and adapted to any challenge throughout history is explored.
The pressure to survive has resulted in changing shapes. Explore the evolution of animal shape and how a slight alteration of a leg or head can mean the difference between life and extinction.
Venom, a deadly natural weapon, has independently evolved in diverse creatures. Bryan Fry shows how the the inland taipan has converted the building blocks of its body into lethal toxins.
Humans are not the only species that can communicate. Simple organisms like bacteria can communicate a strategy that lets them cooperate to take down creatures much bigger than them.
Speed, the ability to react and move, can often mean the difference between life and death in the animal kingdom. Some animals have evolved into championship fliers, swimmers and runners.
Discover how dinosaur's evolved eyes helped them become successful hunters and learn how primates evolved unique adaptations to see colors helped them find food.
