brachycephaly and globularity seems associated but they are not identical - globularity, at first sight could favorize interconnectivity in brain but it is a picture, i don't know if it is reality - I suppose the frontal region development is of greater importance - that said, brachycephalic is only a two dimensions concept, and does not cover integraly globularity - Europeans became more and more brachycephalic since Antiquity and since hte 1900's the process reversed, so? Maybe we are becoming less intelligent? in fact opposite tendancies could be in play: social life and selection linked to it, but also mechanical constraints linked to overall stature - as often multifactors result
