Historic individuals in China practiced human head-shaping about 12,000 years in the past — which means they certain some kids’s maturing skulls, encouraging the heads to develop into elongated ovals — making them the oldest group on report to purposefully squash their skulls, a brand new examine finds.
Whereas excavating a Neolithic website (the final interval of the Stone Age) at Houtaomuga, Jilin province, in northeast China, the archaeologists discovered 11 elongated skulls — belonging to each men and women and starting from toddlers to adults — that confirmed indicators of deliberate cranium reshaping, also referred to as intentional cranial modification (ICM).
“That is the earliest discovery of indicators of intentional head modification in Eurasia continent, maybe on the earth,” mentioned examine co-researcher Qian Wang, an affiliate professor within the Division of Biomedical Sciences on the Texas A&M College School of Dentistry. “If this follow started in East Asia, it doubtless unfold westward to the Center East, Russia and Europe by way of the steppes in addition to eastward throughout the Bering land bridge to the Americas.” [In Images: An Ancient Long-headed Woman Reconstructed]
The Houtaomuga website is a treasure trove, holding burials and artifacts from 12,000 to five,000 years in the past. Throughout an excavation there between 2011 and 2015, archaeologists discovered the stays of 25 people, 19 of which had been preserved sufficient to be studied for ICM. After placing these skulls in a CT scanner, which produced 3D digital photos of every specimen, the researchers confirmed that 11 had indeniable indicators of cranium shaping, comparable to flattening and elongation of the frontal bone, or brow.
The oldest ICM cranium belonged to an grownup male, who lived between 12,027 and 11,747 years in the past, in keeping with radiocarbon relationship.
Archaeologists have discovered reshaped human skulls all all over the world, from each inhabited continent. However this specific discovering, if confirmed, “will [be] the earliest proof of the intentional head modification, which lasted for 7,000 years on the similar website after its first emergence,” Wang informed Stay Science.
The 11 ICM people died between ages three and 40, indicating that cranium shaping started at a younger age, when human skulls are nonetheless malleable, Wang mentioned.
It is unclear why this specific tradition practiced cranium modification, but it surely’s potential that fertility, social standing and wonder may very well be components, Wang mentioned. The individuals with ICM buried at Houtaomuga had been doubtless from a privileged class, as these people tended to have grave items and funeral decorations.
“Apparently, these youth had been handled with an honest funeral, which could recommend a excessive socioeconomic class,” Wang mentioned.
Regardless that the Houtaomuga man is the oldest identified case of ICM in historical past, it is a thriller whether or not different identified cases of ICM unfold from this group, or whether or not they rose independently of each other, Wang mentioned.
“It’s nonetheless too early to assert intentional cranial modification first emerged in East Asia and unfold elsewhere; it could have originated independently in other places,” Wang mentioned. Extra historical DNA analysis and cranium examinations all through the world could make clear this follow’s unfold, he mentioned.
The examine was revealed on-line June 25 within the American Journal of Bodily Anthropology.
