It's one of those eternal discussion things. When
did humans domesticate animals, plants, etc.? Where did they do it ? and were there multiple centres/cultures that did so? or was it a central thing and knowledge diseminated ?
Mind too that we're only finding the smallest traces of the past; most of it was organic and it decays/rots/is eaten
That's why archaeologists and other researchers have to think 'outside the box' and consider things like peat cores, varves and the geological record too.
A predominance of certain pollens within cores or varves that appear as a definite change, just for instance, might mean tree clearances and grain planting/crop production….within that area. Then define the area and culture within a date range. Tie it in with the date range to a wider area, see if there are commonalities that are statistically significant.
It's like a jigsaw with most of the pieces missing and those that survive have been soaked and dried, crumpled and buried.
Interesting though
