Deconstructing the spread of agriculture
Did agriculture move in the hands of people, or with the words of people? Or, somewhat more prosaically:
Two alternative models have been proposed to explain the spread of agriculture in Europe during the Neolithic period. The demic diffusion model postulates the spreading of farmers from the Middle East along a Southeast to Northeast axis. Conversely, the cultural diffusion model assumes transmission of agricultural techniques without substantial movements of people.
Actually not just Europe. And the jury is still out. Two recent paper both tilt towards cultural diffusion, both in Europe (which is where the above quote comes from; but not everybody agrees) and Island SE Asia. This sort of work is mainly done by anthropologists and human geneticists. Sometimes the genetics of livestock or crops are brought into play, but only rarely both at the same time. A grand synthesis of human, livestock and crop genetic data, archaeology and anthropology remains to be done…
Farming systems atlas taking shape
Our friends at CIAT are putting together a lot of geo-referenced data on farming systems around the world. Check out in particular what they call the Generation Atlas. Below is a screen shot of a detail of the map of the distribution of aluminium toxicity in Africa.
Somebody somewhere is probably working on mashing this up with the germplasm data from SINGER or even the crop wild relatives data from GBIF, a la FIGS.

- Computer program recognizes cattle breeds.
- NZ dope getting stronger? Maybe, and I hope so, but probably impossible to tell from this study.
- Need farming systems data?
- Psst, wanna know how to determine the essentially derived status of maize inbred lines?
- High zinc wheat works.
- Michael Jenkins of Forests Trends on using markets to save biodiversity.
- The phylogeny of ramie and its wild relatives sorted out. Sort of.

An orange revolution in the Pacific
Via our friend Lois Englberger comes news of the nth project involving orange crops, where n is a large positive integer. This one is on orange-fleshed sweet potatoes — and indeed other high beta-carotene crops — in the Solomon Islands. The International Potato Centre (CIP) has a catalogue of orange varieties for Africa. I just hope everyone is not forgetting all the other varieties.
