No towering zygomatic bones does not mean round face and big cheeks.
but more a rombic face or an upside down egg
the photo of the liitle asian girl is a little american girl, an Inuit,
Inuits have the most big cheeks and the most round face as a sum.
as you see hunters-gatherers have big cheeks and round face, IE were after Neolithic agricultural boom, milleniums after Summerians so alpine race (anthropometric race) should exist in Europe when IE came, and continue to exist via female population most than patriarchcal which was IE incomers
I thought I 'd had left (not "leaved" as I wrote some day!) the phenotypical aspect of things but I'm obliged to say something sometime:
there was more than a hunter-gatherer type: post-paleolithic descendants of 'cro-magnon' (plus a partly negroid version 'grimaldi', perhaps a crossing, and mesolithic as 'brünn', 'combe-capelle', 'chancelade' and their crossings (my bet) giving birth to 'teviecoid' mean, 'mugemoid' mean:
the 'cro-magnon' stock has low and broad faces, the bizygomatics were broad, but in accord with a broad bigonials (jaw), the brachycephalized 'borreby', whatever its true filiation, presents the same saqure face -
BUT the other phylum, 'brünn', 'combe-capelle', 'chancelade' has a high and narrow gace, solid too but where bigozygomatics are very broader than bigonials: very contrasting faces, without speak about other clear differences of skeletons: so if we cannot speak about a KNOWN I-E PHENOTYPE AND GENETIC, we cannot to much speak about an unique "hunter-gatherer" type!
as said by someone, broad byzygomatics are not linked by force to cheeky visage (flesh and diet influence), and not linked at all to broad jaws!
