Archaeologists have lately confirmed {that a} Japanese society that prospered between roughly A.D. 200 and A.D. 600 on the island of Tanegashima modified craniums for mysterious causes.
Whereas the current paper explains that the modified skulls bolstered group identification and belonging, they might even have one thing to do with the native shellfish commerce. The Hirota folks clearly valued mollusks, as they lined their graves with funerary items constructed from shellfish introduced from lots of of miles away.
That stated, the research in the end can’t verify the explanation for the modifications nor how they’d have assisted within the seafood commerce.
Misshapen Skulls
Societies all world wide have practiced cranial modification, the strategy of wrapping an toddler’s cranium with fabric for the primary few months of its life, so its cranium fuses in an uncommon form.
The Mayans superior the approach utilizing a cradleboard-like equipment, whereas more moderen teams in Europe and Asia have practiced cranial modification as nicely. In Toulouse, France, low-income dad and mom hooked up bands and cloths to their infants’ heads as late because the early twentieth century.
In contrast to many societies, the Hirota practiced cranial modification equally and sure the heads of each women and men. In both case, the binding flattened the again of the cranium and shortened the cranium’s total peak.
Have been the Skulls Altered Deliberately?
The Hirota skulls from the current research got here from a large-scale burial website, which scientists have twice excavated. In the course of the first dig – carried out between 1957 and 1959 – the archaeologists discovered the misshapen skulls however had no approach to inform if they’d gotten that manner by accident or by modification. The current mission sought to settle the 60-year-old query.
The researchers analyzed each 2D and 3D pictures of the skulls and in contrast them to bones from different close by archaeological websites, to see if the Hirota’s stood out. They did when in comparison with these of the Doigahama website from Southwestern Japan, and the identical was true of the traditional skulls discovered on close by Kyushu Island, people who belonged to the Hirota’s hunter-gatherer predecessors.

The crew concluded that the outcomes “strongly instructed intentional cranial modification,” in line with an announcement. Though, the the reason why nonetheless stay unclear.
“Our findings considerably contribute to our understanding of the apply of intentional cranial modification in historical societies,” stated Noriko Seguchi, an affiliate professor at Kyushu College’s School of Social and Cultural Research, in an announcement. “We hope that additional investigations within the area will supply further insights into the social and cultural significance of this apply in East Asia and the world.”
