Min, the Toba HSS bottleneck hypothesis arose before the genetic revelation that (a) HSS interbred with HSN and the Denisovans, and (b) other 'species' were flourishing up until the late Pleistocene / early Holocene. Nobody has bothered to reject the hypothesis since there has been no clearcut alternative put forth as to why HSS tends to be so homogenous, arising from a small group of HSS who apparently numbered about 2-10,000 about 70kya.I just have a little trouble with the concept of a species-specific volcano.
