Apparently, maize recovered from ancient burials in NW Argentina is genetically “almost identical” (whatever that means!) to the landraces still being grown in the area. I wonder if it was prepared in the same way too. This piece in the Washington Post certainly shows that maize culinary traditions are strong, and can go back a long way.
Etruscan cattle
A new study tries to disentangle the mystery of the origin of the Etruscans by looking at the genetics of the cattle currently found in the area of central Italy which takes its name from that ancient civilization, Tuscany (or is it the other way around?). It turns out that, unlike cattle from other parts of Italy, cattle from the Etruscan lands shows genetic affinities with Anatolian breeds. According to the Italian researchers, the Etruscans came to Italy from Turkey, and they did so by sea. I wonder if it will be possible to recover DNA from the remains of ancient Etruscan cattle…
The marula and the elephant
The sweet, juicy fruits of the marula tree (Sclerocarya birrea) are widely eaten in the miombo woodlands of southern Africa, and are also used to make the delicious Amarula Cream liqueur. But it’s not just people who like them: elephants will walk a long way for a marula feast. This piece looks at some of the evolutionary consequences.
Chocolate from tree to cup
In honour of Valentine’s Day, albeit a day late, a chocolate-flavoured post today. First, from the great Howstuffworks, How Chocolate Works. Then, ever wondered where you can get the best hot chocolate in New York or Paris? Well, wonder no longer, and check this out. And finally, news that a network has been established to conserve cacao diversity. You can read the Bioversity International press release here.
Dual-purpose weeds
Two stories today about different ways of looking at the same plant. I was walking along a fairly major road in a suburb of Nairobi this morning and I noticed a “jua kali” artisan selling interesting-looking stuff. “Jua kali” is Kiswahili for “under the sun” and is commonly used hereabouts to refer to the informal sector, because under the sun is where most of them transact their business, as in this case. Anyway, I ended up buying the magazine rack pictured here, for about US$15.
The frame is metal, but the rest is made of a tough-looking fibre I couldn’t place. I asked what it was and was very surprised to hear that it is water hyacinth. That’s a very cool use for a noxious weed, which is again choking up Lake Victoria, after a successful biological control effort. It turns out that making furniture out of the stuff is not all that uncommon.
And here’s the story of the mesquite bush in Kenya, a useful plant in some parts of the world (even used as food in some cultures), but seen as a terrible invasive here, in particular by pastoralists in the drier areas of the country. But I bet people are working on novel, profitable uses. Maybe someone in northern Kenya is already marketing mesquite honey, or carvings made of mesquite wood?
