National Geographic reports on a study in Proceedings of the National Academy of Sciences that concludes that goats “accompanied the earliest farmers into Europe some 7,500 years ago, helping to revolutionize Stone Age society”. Goats are genetically much more diverse than other domesticated animals. This suggests they spread more quickly, and moved more rapidly, than other livestock.
It is fascinating how for most livestock species that have been looked at there is evidence of multiple domestication “events.” But I don’t think anyone’s had a look at when and where these took place and compared this with what is known about plant domestication.
Ok, maybe I’m wrong. Have a look at this article about a pre-Neolithic temple at Gobekli Tepe in Turkey. Apparently, einkorn wheat has been genetically linked to here, and wild pigs were first domesticated nearby.
