What is Universal Common Descent?

@Billcole

The case he made was that the bacteria would not survive unless the 2 adaptions occurred. In this case his math is right because until the two adaption occurred death is guaranteed. According to Lynch’s model, adaptions requiring multiple mutations take lots of time and large populations to fix. Since there are probably thousands of mutations to convert a Chimp to a Human this does pose doubt to the CD inference.

Hi Bill,

Behe’s model is not about bacteria - it’s about all organisms.

That post I keep referring you to - the one where phage lambda generates a new binding site with four mutations - is really quite informative on this issue. I think it would greatly help you understand what Behe is arguing, and why his argument just does not work.

Why not have a read through and then ask questions if you have any?
