It's a tough, violent and lethal world out there and it's been that way since the dawn of time. Roughly 99 percent of all species have become extinct. What enabled that other one percent to survive the cutthroat competition? Their ability to...Evolve. For man, beast and nature, it's been a constant battlefield. This fascinating series blends spectacular live-action natural history sequences, lifelike computer graphics, epic docudrama and experimental science to illustrate the never-ending struggle to prevail. Some strategic advances were anatomical (eyes and body armour) while others were behavioural (movement, communication and sex). While the bald eagle developed telescopic vision capable of spotting a hare a mile away, the shark evolved the act of sex as we humans know it. What else propelled creatures large and small to survive? Evolve traces the history and importance of these adaptations from their earliest beginnings to today. It's nature's longest lasting battle and every creature on Earth is part of it.
