Using ancient grains to remap perceptions of Central Asia
The Silk Road Symposium held at the Penn Museum in March 2011 was clearly quite a get-together, judging by the personalities involved. Some of the presentations are on Youtube, including one by Dr Michael Frachetti on “Seeds for the Soul: East/West Diffusion of Domesticated Grains,” which has been picked up and discussed by Dienekes on his blog. It’s really worth listening to the whole talk, even at 45 minutes, but in case you don’t have the time, here are the main points.
Dr Frachetti excavated at a place called Begash in Uzbekistan. This is a site which goes back to at least 2500 BC and was used by nomadic pastoralists for many centuries. The dig came up with the earliest evidence of wheat and broomcorn millet in Inner Asia, dating back to about 2200 BC. At left is what the seeds they found look like (click to enlarge).
But here’s the thing. There’s no evidence that the people living at Begash at the time actually ate these things. ((Now, I know that Central Asia does not necessarily mean the Silk Road, and things have changed since then anyway, but for an entertaining look at the food of the latter, check out the recent post at The Edible Schoolyard.)) Their teeth just don’t look like the teeth of people who have a lot of cereals in their diet. Basically, no cavities. And there was no evidence of processing either. So what was happening?
The seeds were recovered from a very particular context — a cremation burial. And only in that context. Along, incidentally, with horse remains. Both the cereals and horses were in fact ritual commodities, the excavators think. Not stuff to be consumed every day, but rather exotic commodities to be wheeled out on very special occasions to make an impression. As Dienekes points out, using wheat for funerary offerings goes on still.
Where did the cereals come from? To cut a long story short, the wheat from the west and the Panicum millet from the east. ((The Panicum miliaceum story is fascinating, with its pre-5000 BCE appearance of cultivated forms in the archaeological record in both China and around the Black Sea, but not in between. It is mentioned as an unsolved puzzle — independent domestication or long-distance contact? — by Prof. Colin Renfrew in his own talk, which refers to the genetic work of Dr Harriet Hunt.)) Which is the reason why Dr Frachetti thinks we need to remap our thinking about Central Asia. It’s not so much that the people who inhabited these regions were peripheral to the great Bronze Age civilizations, but rather (or, perhaps, also) that they were the link between them.

- Genetic diversity of Brassica oleracea var. capitata gene bank accessions assessed by AFLP. Czech genebank; subgroups reflected place of origin.
- Optimizing the cropping mix in North Darfur State, Sudan. A study of Umkdada district. “…the results of the model were different from the real practices of the farmers.” Oh dear. To improve the fit, schoolboys should work in the fields more. And crops should fetch more. The dismal science indeed.
- Climate-driven simulation of global crop sowing dates. Ok, this model works. You can predict sowing dates under rainfed conditions for various annual crops from climatic conditions. Not entirely sure why you would want to, though.
- Exploring some of the myths of land use change: Can rural to urban migration drive declines in biodiversity? Yes, counter-intuitively, at least in the forests of Mexico’s southwestern highlands. More from Conservation Magazine.
- Pollination services in the UK: How important are honeybees? Quite a bit, but maybe not as much as previously thought. It’s the wild bees, stupid!

- The potential of plant viruses to promote genotypic diversity via genotype × environment interactions. The negative effect of White Clover Mosaic Virus (WCMV) infection on performance differs from white clover genotype to genotypes, which means differential selection, which means negative frequency-dependent selection in host populations, which means diversity.
