For You Lot Data - Piece Of Cake Pleistocene Human Mandibles From Borneo's Niah Caves May Hint At Ancient Diets

Three human mandibles may render novel insight into the diet of Late Pleistocene hunter-gatherers inward Borneo, according to a written report published inward the open-access mag PLOS ONE past times Darren Curnoe from the University of New South Wales, Australia, in addition to colleagues.

Little is known virtually the early on hunter-gatherer populations that lived inward isle Southeast Asia since human remains from the Late Pleistocene-early Holocene era are extremely rare. The Niah Caves inward the northeast of Kalimantan accept been identified equally a promising archaeological site for learning virtually the early on humans that dwelled inward this region.

Curnoe in addition to colleagues examined 3 human mandibles that were previously excavated from the West Mouth of the Niah Cave inward 1957. Using Uranium-series dating techniques, the researchers justice that 1 of the mandibles is 28-30,000 years old, piece the other 2 are at to the lowest degree 11,000 in addition to 10,000 years old, respectively. The oldest mandible of the 3 was smaller in addition to to a greater extent than robust compared to other Late Pleistocene mandibles, in addition to this may advise that it was champaign of written report to strain that could accept been caused past times consuming tough or dried meats or palm plants, a diet that has previously been identified inward the Niah Caves.

The researchers advise that their written report helps render insight into the diet of ancient people living nigh tropical rainforests, a share which has been previously identified equally facing economical difficulties. Through their potential consumption of raw flora foods in addition to dried meats, the hunter-gatherer populations living inward this share or in addition to then the Late Pleistocene may accept been adapting to their economically challenging environment.

"These early on modern humans were seemingly adapted to a hard life inward the tropical rainforests amongst their really modest bodies in addition to ruggedly prepare jaws from chewing actually tough foods," says Curnoe. "They tell us a lot virtually the challenges faced past times the earliest people living inward isle Southeast Asia."
