Back in 1929, archaeologists unearthed several human skeletons (seven adults and three children) while excavating Skuhl Cave just south of Haifa, Israel. Dating back 140,000 years to the end of the Middle Pleistocene, most were classified as early Homo sapiens. But one skeleton was that of a child, between the age of 3 and 5 years old whose features seemed to show a mix of early human and Neanderthal characteristics. A new analysis involving CT scanning may resolve the long-standing debate, according to a new paper published in the journal L’Anthropologie.
Neanderthals and Homo sapiens traded genes frequently during the period when their populations overlapped. "The two came in contact as modern humans began their major expansion out of Africa, which occurred roughly 60,000 years ago," Ars Science Editor John Timmer previously reported. "Humans picked up some Neanderthal DNA through interbreeding, while the Neanderthal population, always fairly small, was swept away by the waves of new arrivals."
Nor is this the first case of a possible hybrid hominid species. In 2018, scientists analyzed a sliver of bone excavated from a cave site in Russia. The findings made global headlines when the team concluded that the individual to whom it belonged—a young girl of about 13, dubbed "Denny"—was the offspring of a Neanderthal mother and a Denisovan father. This suggested that rather than dying out, Neanderthals may have been absorbed by other species; such inbreeding may have been more common than previously thought.
