- Gene controlling rice architecture may hold promise for increased yield. Unless, of course, it doesn’t.
- Attempts to control a deadly cassava virus in central Africa. I hope someone is conserving those susceptible varieties. They may be useless now, but who knows what the future will bring? And more questions.
- And following the Kibale post, more on non-timber forest products and their trade.

- Photos of the 6th Annual Hawaii Seed Exchange.
- More Pacific stuff: 3000-year-old Lapita chickens were haplogroup E, “a geographically widespread major haplogroup consisting of European, Middle Eastern, Indian, and Chinese domestic chickens.”
- More on that thing about the gut biota being adapted to ethnic diets.
- Wolves may have been turned into dogs earlier than previously thought.
- Organic farming good for underground mutualists. Which sounds totally appropriate somehow.
- Crop wild relatives: all you ever needed to know.
- Bring back bees by bringing back the boy scout bee-keeping badge.
- Here’s a weird one. US to cut 1.5 trillion calories from food by 2015. And there are 1 billion hungry. You do the math.
- Farmers rear endemic moths on intercropped host plants for high quality silk in Madagascar. Enough hot buttons in there for ya?

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…
