They are one of evolution's most useful and prevalent inventions. Ninety five percent of living species are equipped with eyes and they exist in many different forms. Learn how the ancestors of jellyfish may have been the first to evolve light-sensitive cells. Discover how dinosaur's evolved eyes that helped them become successful hunters. Finally, learn how primates evolved unique adaptations to their eyes that allowed them to better exploit their new habitat, and how the ability to see colours helped them find food.
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. 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. The series premiere, Eyes, was nominated for an Emmy for Outstanding Science, Technology and Nature Programming.
