Had an interesting discussion with a knowledgeable medico a few weeks back. I was questioning how life could evolve and mutate so quickly. He pointed out that recent discoveries indicate that most of these evolutionary-possibilities lie dormant in our DNA, just waiting to be switched on. Just how and when this switching occurs is a hot topic. I found this concept absolutely fascinating.
