Сеча як свідоцтво переходу від мисливства-збирання до тваринництва
Researcher had previously documented some unusually high levels of salts around Aşıklı Höyük, and were perplexed by what they meant. Using this data and others, the new study supports the idea that the salts likely came from the urine of humans, sheep and goats. The study uses the abundance of the salts over time to track the growth of the community and its animals over a period of 1,000 years.
Working with Turkish archaeologists, including Istanbul University’s Mihriban Özba?aran, who heads the Aşıklı Höyük dig, the team collected 113 samples from all across the site — from trash piles to bricks and hearths, and from different time periods — to look at patterns in the sodium, nitrate and chlorine salt levels.
They found that, overall, the urine salts at A??kl? Höyu?k increased in abundance over time. The natural layers before the settlement was built contained very low levels of salts. The oldest layers with evidence of human habitation, spanning 10,400 to 10,000 years ago, saw slight increases but remained relatively low in the urine salts. Then the salts spike during a period from 10,000 to 9,700 years ago; the amount of salts in this layer is about 1,000 times higher than in the preceding ones, indicating a rapid increase in the number of occupants (both human and animal). After that, the concentrations decrease slightly.
Abell says these trends line up with previous hypotheses based on other evidence from the site — that the settlement transitioned first from mostly hunting sheep and goats to corralling just a few, then changed to larger-scale management, and then finally shifted to keeping animals in corrals on the periphery of the site as their numbers grew. And although the timing is close to what the study authors expected, the sharp change around 10,000 years ago “may be new evidence for a more rapid transition” toward domestication, says Abell.
Using the salt concentrations, the team estimated the number and density of people plus sheep and goats at Aşıklı Höyük, after accounting for other factors that might have influenced the salt levels. They calculated that around 10,000 years ago, the density of people and animals occupying the settlement jumped from near zero to approximately one person or animal for every 10 square meters. By comparison, modern-day semi-intensive feedlots have densities of about one sheep for every 5 square meters.
