Dorian Fuller has answered Paul Gepts’ comment on Dorian’s post at The Archaeobotanist on the multiple origin of agriculture, which I originally blogged about a few days ago. Let’s remind ourselves of the argument.
This was Dorian’s parting statement on the original post:
…agriculture, like modern human behaviour, was not a one time great invention, but the product of social and environmental circumstances to which human groups with the same cognitive potential responded in parallel ways.
Paul Gepts countered with this:
As a geneticist, I am somewhat surprised that the issue of parallel inventions of agriculture is still an issue… biochemical and molecular data also show distinct, and likely, independent domestication in different geographical areas, not among only among different crops, but also within a crop gene pool.
And now Dorian again:
My sense is that most of the genetics community has shifted towards seeing multiple areas of independent origin, but within archaeology there is still a penchant for reducing historical complexities to as few origins as possible — often focusing on where more archaeological research has taken place rather than considering other forms of evidence (biogeography, genetics) that should encourage us to take up research in the less-explored or unexplored areas.
