Presumably his agreement was only to what you wrote about the function of NS.-In my view the Darwin mechanism of random mutation and natural selection following is entirely a passive process. Random means 'lucky' if it is a good change in the genome, but it may be neutral in effect or bad for the species, each variety of change about 1/3rd of the outcomes. The 'good' changes start out as recessive genes and with the guidance of natural selection to challenges in nature eventually become dominant. Natural selection responds to random challenges, making natural selection an active process only after random changes in nature, both climatological and biological, preditors, etc. In conclusion, NS becomes an active participant in the speciation process only after a long series of random events, and contingent changes. NS seals the fate of the new species, and at this juncture assumes a major role. All the other mechanisms in the genetic cascade of epigenetic controls are more active in initial responses to natural challenges, for they are actively changing the genome in the adaptations that are necessary for surviorship. In the end all are equal in importance. Use this analogy: locking the barn door after the horse escapes does not fit, but capturing the escaped horse and then putting him back in the barn and locking the door is the correct analogy. NS locks the door. Several equal parts, no single linch-pin.
