“[The Tao River Archaeological Project] was begun in 2012 to investigate technological changes in Northwest China during the late third and early second millennia B.C.E., a period during which new materials, like metals, were introduced to the region, along with new domesticated animals and plants (including cattle, sheep, goats, and horses, and wheat and barley)—all seemingly at different times and places.”
