Just to nit pick Cro-Magnon people were the Eurasians that populated Europe after the hybridisation event(s) between Neanderthals and AMH. We know from sequencing studies that they had a higher level of Neanderthal alleles than modern Europeans. Their larger brain size suggests a liger-like overshoot in brain growth given the constraints of the birth canal. I suspect Cro-Magnon women had an even more terrible time in childbirth than modern women.
