Prehistoric mass murder site discovered by Kenyan lake
Proof of intentional killing is extremely rare among prehistoric hunter-gatherers, but the evidence found at Nataruk by Lake Turkana is clear-cut. Skeletons dating to 10,000 years ago, bearing marks of a violent death and possibly bondage, provides fresh evidence that prehistoric hunter-gatherers did not necessarily live in bonhomie. Disturbingly, two of the 12 people found by Lake Turkana, Kenya were not marked by signs of violence but seem to have died with their hands bound, a team of archaeologists reported in Nature.
"Evidence for inter-group violence among prehistoric hunter-gatherers is extremely rare," writes the team led by Marta Mirazón Lahr of Cambridge University. Yet she found some. She and her colleagues discovered the remains of at Nataruk, a site near the edge of Lake Turkana, in 2012. Among them were ten bodies with clear signs of lethal traumas.
One man had been bashed on the head twice, above the right eye and on the left of his skull, smashing the bone. Another had a small obsidian knife embedded in his skull, but what killed him was probably a completely different weapon, which was used to crush his face. Wounds found on the head and neck bones of others could have been caused by arrows, which indicates that the attackers were distant, suggesting inter-group conflict. Some suffered broken knee and hand bones. One body was of a woman in advanced pregnancy: the position of her body and limbs suggest she had her feet and hands bound. Stone tools were found too, 131 with the bodies and hundreds more right around them.
These ancient people, whom the authors date to 9,500-10,500 years ago, had not been lovingly buried: the bodies were not found in any orderly orientation or manner. Six of the dead were children. At least, observe the scientists, there was no evidence of 'trophy-taking' (such as scalping).
The Nataruk site is not the first or even the oldest evidence of actual inter-group war. In mid-2014 scientists from Bordeaux University in France reanalyzed bodies in a graveyard dating back roughly 13,000 years in today's Sudan, and concluded they had come across not only the oldest evidence of war, but racial war at that. The bodies were of two distinct types: One group involved in the ancient battles in Jebel Sahaba by the Nile River were tall with relatively short torsos, projecting features and broad noses. The other group was shorter, had longer torsos and flatter faces.
The Turkana finds show the battle in Sudan had not been a bad-tempered blip in the history of Neolithic man. The reason for the slaughter cannot be known; although Turkana is a fertile site, there are signs of early settlement, such as clay pottery, so one possibility is that that groups in the area were struggling over resources. Or maybe they all had plenty of resources but had violent tendencies toward outside groups.
Some anthropologists prefer to believe hunter-gatherers were peaceful. If a group encountered unpleasantness, they could simply move on. Why fight if they could flee? Others suspect the opposite, with some even postulating that internecine violence, and the development of stone weapons, is exactly how prehistoric populations began to spread worldwide. In any case, the archaeologists believe the Nataruk finds show "intentional killing" of a small band of foragers, which constitutes, they say, "unique evidence of a warfare event among hunter-gatherers in prehistory".
