...imagine how a random mutation might have produced a path of light-sensitive cells that helped a primitive creature tell day from night. You can also imagine how another mutation might have bent this patch of cells into a concave shape that could detect the direction a light or shadow was coming from-helping creatures with the mutation stay clear of predators.

He grew up without a television or radio in a Mennonite household in Pennsylvania, and he needed permission from a pastor to wear racing tights in public. Landis still won't conform. After riding shotgun for Armstrong on the U.S. Postal team for the past three Tours, he jumped to the Swiss Phonack squad...
