A New Study of the History of Pig Domestication
As I understand it, additional mitochondrial DNA analysis led them to complicate the 'multiple origins of domestication' argument by showing how pigs domesticated in the Near East were taken to Europe by early farmers, who then domesticated their own wild boars which eventually replaced the imported animals. Migrating farmers then took the European pigs to the Near East where they pushed out the original domesticated animals. The researchers used these pigs, as Maugh put it, as "an excellent proxy for tracing human movements" to support the hypothesis that farming was introduced to Europe by migrating Near Eastern farmers between 10,000 and 6,000 years ago. According to Maugh's excellent summary of an increasingly complicated history involving archeology and genetic research, Larson and his team now want to extend this analysis to pigs in Asia to see how far these European pigs might have been taken.
In tracking down the news of this new research I discovered that Oxford University Press will be publishing a collection of essays in November entitled Pigs and Humans: 10,000 Years of Interaction. You can check out the table of contents here. It will be great to have much of the complex and interesting work on domestication synthesized, although based on today's post, there seems to be more and more discovered all the time.
