stilted skull extension   has been practiced by a strangelyhigh issue of culturesin practically every box of the world , from Western Europe and the Americas to the Far East and Africa .

But why would people bond their baby ’s heads to give themselves a pear - shaped skull ? Well , for one 600 - yr - old civilisation in South America , it   was probably to show you were a VIP .

A new study , published in the journalCurrent Anthropology , has taken a look at elongated skull of the Collagua hoi polloi who inhabit in the Colca Valley in Confederate States of America - eastern Peru around 1100 to 1450 CE .

Through measuring carbon and nitrogen isotope analysis of the bones , the research worker showed that the Collagua women with elongated distended heads ate a more varied dieting , indicate that they were perhaps more inside . These remains of these women also appeared to have few signaling of physical ferocity against them , once against suggesting that they were from a higher echelon of beau monde .

The Collagua were persistently under the terror from the Inca Empire around this time . For the women to be proudly display your privilege with unusual skull might have also have been particularly prominent during times of social strives and state of war , as it do like a symbolization of their corporate individuality , just like a land proudly waving a flag .

The bailiwick also made clear that more and more skulls were being elongate , even among the lower classes , as the pressure from the Inca Empire develop . Perhaps they were looking for a gumption of belong during a time of strife ?

“ In times of crisis and social upheaval , the creation of new sort of collective identity can beef up or undermine political reintegration , ” the work author , Matthew Velasco of Cornell University , note .

“ It may have advance coherence among local elites and facilitated cooperation at high stratum of inclusiveness to align agropastoral central , manage irrigation , or mobilise against away forces , including ( but not confine to ) the encroach Inka state . ”

Artificial cranial deformations usually involve tightly binding a baby ’s squishy chief with bandage or clamping it into between wooden board in guild to deform its growth . This is just one insight into one refinement ’s use of elongated skulls , so it does n’t necessarily represent all instances of it . After all , it occurred in myriad unlike groups throughout chronicle .

Nevertheless , the legal age of archaeologist think that this recitation   often had something to do with social status and the sentiency of belonging to a group . Sorry , there ’s still no word on the alien connexion yet !
