Tracing European founder lineages in the Near Eastern mtDNA pool.
There has been substantial back-migration into the Near East, there was a founder effect or bottleneck associated with the Last Glacial Maximum, 20,000 years ago, and a way to account for multiple dispersals of common sequence types is suggested. Expand
Evidence for two independent domestications of cattle.
Application of a molecular clock suggests that the two major mtDNA clades diverged at least 200,000, and possibly as much as 1 million, years ago, as evidence for two separate domestication events of different subspecies of the aurochs, Bos primigenius and Bos taurus. Expand
Genetic evidence for Near-Eastern origins of European cattle
The limited ranges of the wild progenitors of many of the primary European domestic species point to their origins further east in Anatolia or the fertile crescent. The wild ox (Bos primigenius),Expand
Microsatellite DNA variation and the evolution, domestication and phylogeography of taurine and zebu cattle (Bos taurus and Bos indicus).
The introgression of zebu-specific alleles in African cattle afforded a high resolution perspective on the hybrid nature of African cattle populations and also suggested that certain West African populations of valuable disease-tolerant taurine cattle are under threat of genetic absorption by migrating zebe herds. Expand
Mitochondrial diversity and the origins of African and European cattle.
The nature of domestic cattle origins in Africa are unclear as archaeological data are relatively sparse. The earliest domesticates were humpless, or Bos taurus, in morphology and may have shared aExpand
DNA markers reveal the complexity of livestock domestication
By comparing mitochondrial and nuclear DNA sequences of modern breeds with their potential wild and domestic ancestors, new insights are gained into the timing and location of domestication events that produced the farm animals of today. Expand
Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.
These patterns retain a strong signal of expansion from the Near East but also suggest that the demographic history of Europe has been complex and influenced by other major population movements, as well as by linguistic and geographic heterogeneities and the effects of drift. Expand
Genetic evidence for the convergent evolution of light skin in Europeans and East Asians.
A case for the recent convergent evolution of a lighter pigmentation phenotype in Europeans and East Asians is supported by the testing for the presence of positive directional selection in 6 pigmentation genes using an empirical F(ST) approach and a role for MATP in determining normal skin pigmentation variation using admixture mapping methods.

African Pastoralism: Genetic Imprints of Origins and Migrations
The genetic signatures of its origins, secondary movements, and differentiation through the study of 15 microsatellite loci in 50 indigenous cattle breeds spanning the present cattle distribution in Africa reveal a major entry point through the Horn and the East Coast of Africa and two modes of introgression into the continent. Expand
Genetic structure of seven European cattle breeds assessed using 20 microsatellite markers.
It is demonstrated that a simple allele-sharing genetic distance parameter can be used to construct a dendrogram of relationships among animals and reflects an extensive underlying kinship structure, particularly for the Swiss Simmental breed and four breeds originating from the British Isles.
