Ancient people inChinapracticed human head - shape about 12,000 long time ago — meaning they bound some children ’s maturing skulls , encouraging the heads to grow into elongate ovals — making them the oldest group on record to purposefully squash their skulls , a novel subject field finds .
While unearth a Neolithic site ( the last period of time of the Stone Age ) at Houtaomuga , Jilin province , in northeast China , the archaeologist find 11 elongate skull — belong to to both male and female and ranging from toddlers to adults — that evidence mark of careful skull reshape , also known as intentional cranial modification ( ICM ) .
The skull known as M45, the earliest known case of head modification on record. It dates to about 12,000 years ago.
" This is the earliest discovery of signs of intentional heading modification in Eurasia continent , perhaps in the world , " enunciate study co - research worker Qian Wang , an associate professor in the Department of Biomedical Sciences at the Texas A&M University College of Dentistry . " If this practice begin in East Asia , it in all probability overspread westward to the Middle East , Russia and Europe through the steppes as well as eastwards across the Bering land bridge to the Americas . " [ In range : An Ancient Long - maneuver Woman Reconstructed ]
The Houtaomuga site is a treasure treasure trove , hold burials and artifacts from 12,000 to 5,000 years ago . During an dig there between 2011 and 2015 , archeologist found the remains of 25 individuals , 19 of which were preserved enough to be analyze for ICM . After putting these skulls in a CT scanner , which produced 3D digital epitome of each specimen , the investigator confirmed that 11 had undisputable house of skull formation , such as flattening and elongation of the head-on off-white , or forehead .
Theoldest ICM skullbelonged to an adult male , who lived between 12,027 and 11,747 years ago , according to radiocarbon date .
The M72 skull is between 6,300 and 5,500 years old.
Archaeologists have find reshaped human skulls all around the domain , from every inhabited continent . But this special finding , if confirmed , " will [ be ] the early evidence of the intentional caput limiting , which live for 7,000 year at the same site after its first emergence , " Wang told Live Science .
The 11 ICM someone exit between ages 3 and 40 , indicating that skull shaping begin at a young age , when human skulls are still malleable , Wang said .
It ’s unclear why this particular culture practicedskull alteration , but it ’s potential that fertility , social status and beauty could be factors , Wang said . The people with ICM buried at Houtaomuga were potential from a inner form , as these individuals tended to have grave goods and funeral decoration .
An excavation at the site during 2010.
" obviously , these youth were treated with a decent funeral , which might suggest a high socioeconomic grade , " Wang suppose .
Even though the Houtaomuga humankind is the oldest get it on typeface of ICM in history , it ’s a closed book whether other known instance of ICM spread out from this group , or whether they rose independently of one another , Wang said .
" It is still too other to claim intentional cranial modification first emerged in East Asia and spread elsewhere ; it may haveoriginated independently in different places , " Wang say . More ancient desoxyribonucleic acid inquiry and skull examinations throughout the world may shed light on this praxis ’s spread , he enjoin .
The study was published online June 25 in theAmerican Journal of Physical Anthropology .
