Re: [asa] Innate design detector?

The latest PNAS has an article on how to evolve complex molecular
systems, not using co-opting:

Evolution of complexity in signaling pathways, Orkun S. Soyer and
Sebastian Bonhoeffer, PNAS 103 (44): 16337-42.

Basically, given a simple starting system plus the accumulation of
mutations, gene duplications, etc. over time, additional steps tend to
get added on. Number of additional steps reflects the level of
selective pressure, etc.
