Re: Is close enough good enough?
As you speak about mutation rates and viability of species...makes me think about sharks.. Possibly one of the older groups that are still about. It has been said that UV radiation is one of the largest causes of genetic mutations. Water filters out UV quite well at moderate depths...Perhaps this is one reason they are still about...
