Ancient human genomes suggest three ancestral populations for present-day Europeans
It is shown that most present-day Europeans derive from at least three highly differentiated populations: west European hunter-gatherers, who contributed ancestry to all Europeans but not to Near Easterners; ancient north Eurasians related to Upper Palaeolithic Siberians; and early European farmers, who were mainly of Near Eastern origin but also harboured west Europeanhunter-gatherer related ancestry.
Genetic Discontinuity Between Local Hunter-Gatherers and Central Europe’s First Farmers
Together, these analyses provide persuasive evidence that the first farmers were not the descendants of local hunter-gatherers but immigrated into central Europe at the onset of the Neolithic.

It is shown that the introduction of agriculture into Europe was followed by a boom-and-bust pattern in the density of regional populations, and the results suggest that the demographic patterns may have arisen from endogenous causes, although this remains speculative.

It is inferred that the −13,910*T allele first underwent selection among dairying farmers around 7,500 years ago in a region between the central Balkans and central Europe, possibly in association with the dissemination of the Neolithic Linearbandkeramik culture over Central Europe.
Late Pleistocene Demography and the Appearance of Modern Human Behavior
A population model shows that demography is a major determinant in the maintenance of cultural complexity and that variation in regional subpopulation density and/or migratory activity results in spatial structuring of cultural skill accumulation.

A stepwise strategy for obtaining reliable nuclear ancient DNA from ancient skeletons is developed, which obtained high-confidence LP-associated genotypes from eight Neolithic and one Mesolithic human remains, using a range of strict criteria for ancient DNA work.

New palaeontological evidence is presented that the neopterygian crown radiation is a Palaeozoic event, and it is demonstrated that conflicts between molecular and morphological data for the age of the Neopterygii result, in part, from missing fossil data.
Lactose digestion and the evolutionary genetics of lactase persistence
Access is provided to a database of worldwide distributions of lactase persistence and of the C-13910*T allele, as well as reviewing lactase molecular and population genetics and the role of selection in determining present day distributions of the lactases persistence phenotype.
A novel polymorphism associated with lactose tolerance in Africa: multiple causes for lactase persistence?
A cohort study of lactose digester and non-digester Sudanese volunteers shows there is no association of -13910*T or the A haplotype with lactase persistence, and reveals the complexity of this phenotypic polymorphism and highlights the limitations of C-13910T as a diagnostic test for lact enzyme persistence status, at least for people with non-European ancestry.
Current perspectives and the future of domestication studies
It is argued that although recent progress has been impressive, the next decade will yield even more substantial insights not only into how domestication took place, but also when and where it did, and where and why it did not.
