Western Europe. Domestication begins, also understood as the selection of the most suitable species and thus the involuntary genetic modification of the species, of various plants such as poppies and oats, but not yet any animals. But the connection with the rest of Eurasia along an East-West axis, and therefore with a similar climate, will soon bring other crops and domesticated animals. All this allows human groups to form villages, have surpluses to support non-productive jobs, larger populations, sustain complex organizations, have writing, technology, armies, and religion. So it makes a difference.
