Anthropologists and geneticists see the origin of agriculture in different ways

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.

  • DNA survey of African village dogs reveals as much diversity as in East Asian village dogs, undermines current ideas about where domestication took place.
  • Fossil doubles age of dog domestication.
  • “When children felt like buying candy, they ran into their father’s fields and returned with a few grams of opium folded inside a leaf.”
  • “The rice, a traditional variety called kintoman, came from my grandfather’s farm. It had an inviting aroma, tasty, puffy and sweet. Unfortunately, it is rarely planted today.”
  • “An era of synthetic gums ushered in the near death of their profession, and there are only a handful of men that still make a living by passing their days in the jungle collecting chicle latex…The generational changes in this boom-and-bust lifestyle reflect a pattern that has occurred with numerous extractive economies…”

  • TreeAid says that sustainable agriculture depends on, well, trees.

Multiple origins of agriculture debated

The point is that 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. The question in both cases is: what were the common denominators of those circumstances?

That’s from a post over at The Archaeobotanist which starts by talking about “modern human behaviour” rather than agriculture, but sees parallel processes at play in the origin of both. So, in the same way that “the cognitive architecture for modern behaviour was around but the innovations that we regard as ‘modern’ emerged when social and environmental circumstances demanded,” and this happened in different places at different times, so likewise the “cognitive architecture” for agriculture was widespread and there were therefore many “centres in which societies converged on agriculture,” with the concomitant “behavioural changes towards manipulation of the environment in favour of the reproduction of a few food species,” triggered by particular “social and environmental circumstances.”

Fair enough, but how is this new? There’s a comment on the post in which Paul Gepts makes this very point

…I am somewhat surprised that the issue of parallel inventions of agriculture is still an issue. The concept of centers of origin/domestication has been around for a century, thanks to Vavilov, Harlan, et al. … I must be missing something here, because for some time agriculture has been considered an example of multiple, independent inventions.

I’m looking forward to following this heavyweight exchange.
