How did a genetically isolated people come to herd cattle and sheep, make cheese, weave wool and grow wheat and millet?
Most likely: neighbouring groups passed on the practices and the animals and crops through trade and contact, with little…Ahead on the evidence, not yet confirmed. It needs two reviews to be accepted.
Where it stands
Three answers have been proposed. Neighbouring groups passed on the practices and the animals and crops through trade and contact, with little… leads, with evidence 3 for: partly supported by its tests. Two are still possible. Of the one narrower question under it, none is answered yet.
Why it matters
This is the question the 2021 result opened. Herding, dairying, wool and both western and eastern crops arrived with no detectable movement of people into the founding population[1]. It is a clean natural case of culture moving without genes.
