In 1994 Swedish zoologists Dan-Eric Nilsson and Susanne Pelger took up the challenge of āevolvingā an eye of the fish type from a patch of photosensitive skin. Using pessimistic estimates of variation, heritability, and selection intensity, Nilsson and Pelger came to the conclusion that it would take 364,000 generationsā¦
