Indian skull shape:
Anthropometry has been traditionally used in the reconstruction of history of particular region. This is one of its numerous pseudo-scientific applications. We know that;
- Communities of a particular lineage/s in a region can change its skull shape because of change in lifestyle (nomadic to sedentary). eg. China and Middle East
- Tribal populations because of restricted food supply and region can drift towards certain type of skull shape.
- Of course, looks of matrilineage generally prevails upon in mixed population as it's more stable. This is in the sense men move or change in any region.
However, anthropometry has been widely used to stereotype the looks of a particular region. Then employ this stereotypical look to give an identity based on present day identities to faceless old populations of that region. And there are still many people who think this is more scientific than skin colour studies to identify the groups.
But thanks to Population Genetics now we can get clear picture of old populations and their relationship to one another. Here too just like skin colour based notions, skull shape based ideas fail miserably.
In India, it's been traditionally thought that Mundas predate Dravidians and IE speakers. Many a time their skull shape has been considered as a standard. Now we know that just like their language their main male lineage (Haplogroup O2a) is observed in Austro-Asiatic populations of SE Asia/S China. But their matrilineage is typical to India. Their looks can't be considered as a standard. We now know that their male ancestry skull shape was entirely different. Therefore, present day look of Mundas is misleading.
We can find such examples in other parts of the world too.
Generally, Finnish were considered as epitome of Nordic look(Blond/Dolichocephalic). But now we know that a big chunk of male ancestry(Y-haplogroup N1c) could have had entirely different look. Only their matrilineage is completly European. Therefore, present day look of Finnish is misleading.
In the case of Mundas and Finnish the original male look would have resembled present day East Asian look. A similar story could be found in North Africa. Light skinned North Africans are predominantly Y-haplogroup E1b1b. This haplogroup and it's closest branch Y-haplogroup E1b1a could be found among their southern dark skinned population. But their matrilineage is predominantly European. Therefore, the present day look of North Africans is misleading. Hilariously, there are Europeans who claim ancient Egyptian civilization as their own. Those people are handicapped by American model of white skin distribution thro' European males. But European male lineages are insignificant in comparison to their female lineage either in North Africa or West Asia. Considering how patriarchy prevailed in the past, probably, dark skinned Africans have higher claim on Egyptian civlization than Europeans.
