This certainly holds true for Europe, where the perceived differences between the earlier Neanderthal populations and later “modern” H. There are many sites which are attributed to what are called “early modern humans” are not always particularly older than “fully” modern humans, nor later than Neanderthal sites.
In fact, these two specimens are significantly atypical.
Very possibly occurringat this time was assimilation of the Neanderthal populations with incoming early modern humans, with differential representation in the resulting genome on the modern human side.
It is difficult to believe that the Neanderthal traits would evolve into the modern form without significant contribution of genes for more gracile features.
The material consists of over 100 specimens from the main cave, and a related side cave that features a triple burial of two adult males and a child: Mladec 5,6, and 46.
The male specimens are very robust, and there is significant sexual dimorphism in terms of morphological variability.
