The primates of the Western Palaearctic: a biogeographical, historical, and archaeozoological review.

The Western Palaearctic is traditionally regarded as a zoogeographical unit which is lacking in primatological fauna. The representatives of this taxonomic group which has been documented within its boundary can be referred to the genera Macaca, Papio, and Chlorocebus, and possibly also to Erythrocebus and Galago. The data for the present research were collected through a review of all previous knowledge of the primates of this biogeographical region, including their history, and through original sightings and direct observation of field signs. Surveys were carried out directly in North Africa, the peninsula of Gibraltar, and in the Sahara. Additional data on primate distribution were obtained through the examination and evaluation of the materials conserved in several museums. A historical and archaeological investigation was also carried out, appraising both archaeozoological fndings and prehistoric and ancient artistic production, in order to evaluate the importance of the monkeys of the Western Palaearctic in relation to local human activities and needs.

Ancient DNA, pig domestication, and the spread of the Neolithic into Europe.

The Neolithic Revolution began 11,000 years ago in the Near East and preceded a westward migration into Europe of distinctive cultural groups and their agricultural economies, including domesticated animals and plants. Despite decades of research, no consensus has emerged about the extent of admixture between the indigenous and exotic populations or the degree to which the appearance of specific components of the "Neolithic cultural package" in Europe reflects truly independent development. Here, through the use of mitochondrial DNA from 323 modern and 221 ancient pig specimens sampled across western Eurasia, we demonstrate that domestic pigs of Near Eastern ancestry were definitely introduced into Europe during the Neolithic (potentially along two separate routes), reaching the Paris Basin by at least the early 4th millennium B.C. Local European wild boar were also domesticated by this time, possibly as a direct consequence of the introduction of Near Eastern domestic pigs. Once domesticated, European pigs rapidly replaced the introduced domestic pigs of Near Eastern origin throughout Europe. Domestic pigs formed a key component of the Neolithic Revolution, and this detailed genetic record of their origins reveals a complex set of interactions and processes during the spread of early farmers into Europe.
