Tracing the Polynesian migrations through DNA, but not only

I know you probably don’t have an hour to spare to listen to a lecture on the evidence for pre-Columbian contacts between Polynesians and South American cultures, but Dr Lisa Matisoo-Smith does a really good job of galloping though the DNA and archaeological evidence from humans, commensals and livestock in a recent podcast from the Bishop Museum. She even mentions crops.

The bottom line? The human anatomical and artifact evidence is compelling, but the DNA is not cooperating yet. At least the human DNA. But listen to it. While you’re preparing dinner or something. I just wish the Bishop had thought to put the slides online too.

  • For UK horticulturalists in need of cash. Wonder if that includes the rosemary collection.
  • I’m pretty sure it doesn’t include AVRDC.
  • Who would no doubt agree with Mark Lynas that “No-one disputes that a balanced and nutritionally-adequate diet is the best long-term solution to vitamin A deficiency and malnutrition in general.” And be as puzzled as the rest of us for the relative lack of funding for research on such a diet.
  • A discussion of why mainstream agricultural science hasn’t got the message across about SRI, courtesy of Facebook. Yeah well, the whole concept of basing interventions on, you know, evidence, is not exactly mainstream. Just ask the balanced and nutritionally-adequate diet guys.
  • Bees are stressed out, the poor things.
  • Creative Commons graphs on changes in vegetable nutrient content.
  • Not all plant viruses are bad.
  • Pat Heslop-Harrison talks DNA, with his usual extraordinary fluency, from 11 mins in.
  • Plant Cuttings! Everything from the botany of food to transcription factors for C4 photosynthesis.
  • Cow genebank proposed.
  • IFOAM gets a TIPI. Vandana Shiva no doubt ecstatic.

Do potatoes have to be humble?

Catching up with my podcast backlog, I’ve just listened to The Food Programme’s episode on Cheap Veg. All good stuff, and well worth listening to in full, especially to hear Sheila Dillon pronounce ethno-botanist as if it were some strange, exotic ingredient; which, I suppose, it is. But you’re all busy folk, so I have gone to the trouble of filleting out the potatoes, as it were. Listen to Oliver Moore as he visits the Irish Seed Savers Association and samples the many delights of potato diversity.
