This comment made me aware that I should probably be more precise about how I view the "new model," which I will provisionally label "Ecotype Persistence" (EP), as being different from Multi-regionalism in the old school. Consider two variables: Full genome content Phenotypically salient characters (controlled by a few selected loci) Full genome content is the whole shebang, and it can be thought of as a proxy for ancestry. Phenotypically salient characters on the other hand are simply a reflection of adaptation's power in a local time and space, sans phylogenetic constraint they can be easily decoupled from ancestry. My own conception of the old Multi-regional model is that it imagined ancient populations with very deep time histories persisting world wide, that is, the full genome content is not only locally specific, but that specificity projects back into time. Modern Chinese are the descendents of Peking Man, just as Europeans ...
