A DNA study of almost a thousand wild and domestic cats from around the world is helping to unravel the evolutionary history of this most numerous of household pets. There are five wild subspecies of nearest-relatives, including one in the Near East, from which all domesticated cats are derived, though there has been subsequent hybridization of house cats with local wild populations here and there. Modern cat breeds can trace their origin to at least five mothers domesticated in the Fertile Crescent around the same time as agriculture started, over 9,000 years ago. And, coincidentally, there’s news also today of archaeological evidence from nearby Cyprus backing up that date.
Cattle and biodiversity
Cattle grazing sustains plant diversity in Dutch dune ecosystems.
Hot is cool
Great opportunities for spices.
Agricultural biodiversity and desertification
Today’s much-reported UN University study on the threat of desertification sent me scurrying for information on a recent training course I had vaguely heard about on the role that genebanks could pay in combating desertification. It turned out to be called, ahem, “The Role of Genebanks in Using Agrobiodiversity to Combat Desertification.” But the search for more information was deeply frustrating. I found a few photos (scroll down a bit), but nothing else. Anyone out there know something about this workshop?
Rooibos and climate change
The wild relative might offer some additional options to rooibos tea farmers in South Africa as climate change hits.
