That natural selection is *part* of the mechanism is close to certain. But there's way more to speciation - kin selection, sexual selection, allopatric/ synpatric speciation. We're discovering some amazing processes by which differential survival rates are maximised. I think that what Pinker meant was that natural selection explains the presence of useful functions in creatures. All of the other mechanisms exist for sure but to get good and useful doohickeys one needs selection. _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
