Tule boat ahoy

You may remember a post I did last summer on sedges called tules. Although not domesticated, tules have (or had) a lot of interesting uses among the Native Americans of California, including in the construction of boats. People still build tule boats, mainly for fun. I bring all this up because of a recent article on some fascinating new thinking about how people spread around the world. It seems that there is increasing evidence that they may have done so by boat, including perhaps during the initial peopling of the Americas from Asia. In which case they could well have gone from kelp bed to kelp bed in tule boats. Incidentally, the oldest boat in the world is a pine dugout made by the Bog People of NW Europe in about 8500 BC.

Cooking the books

The news that the DNA in medieval parchments is to be fingerprinted has been making quite a splash. Parchments are made of animal skins, of course, and it seems that it is possible to recover DNA in decent shape — the latest example of archeogenetics. The idea is to produce “a taxonomy of manuscript manufacture,” which must be of tremendous excitement to medievalists. But John Hawks describes another possible application in his anthropological blog that’s more in line with our agrobiodiversity interests here:

…the results may be equally useful for understanding the processes of animal breeding in medieval Europe. Today’s domesticated breeds are a remnant of a much larger diversity of local breeds that once existed. People bred animals both locally by selection and across large regions by introducing favored animals from long distances. Sometimes they favored diversity — and considering the revival of interest in legacy breeds like Highland cattle.

Wish I’d thought of that…
