Power and Limitations of Inferring Genetic Ancestry Open
Background The recent emergence of technologies that capture and analyse genetic variation patterns obtained from a person's DNA sample has led to numerous academic and commercial endeavours to infer individuals' ancestries. In theory, a p…

The evolutionary demise of a social interaction: experimentally induced loss of traits involved in the supply and demand of care Open
Phenotypic plasticity enables animals to adjust their behavior flexibly to their social environment—sometimes through the expression of adaptive traits that have not been exhibited for several generations. We investigated how long social a…

Dense sampling of ethnic groups within African countries reveals fine-scale genetic structure and extensive historical admixture Open
Previous studies have highlighted how African genomes have been shaped by a complex series of historical events. Despite this, genome-wide data have only been obtained from a small proportion of present-day ethnolinguistic groups. By analy…

The evolutionary demise of a social interaction: social partners differ in the rate at which interacting phenotypes are lost Open
Phenotypic plasticity enables animals to adjust their behaviour flexibly to their social environment – sometimes through the expression of adaptive traits that have not been exhibited for several generations. We investigated how long socia…

Structure and ancestry patterns of Ethiopians in genome-wide autosomal DNA Open
We review some of the current insights derived from the analyses of new large-scale, genome-wide autosomal variation data studies incorporating Ethiopians. Consistent with their substantial degree of cultural and linguistic diversity, gene…

The genetic landscape of Ethiopia: diversity, intermixing and the association with culture Open
Summary The rich linguistic, ethnic and cultural diversity of Ethiopia provides an unprecedented opportunity to understand the level to which cultural factors correlate with -- and shape -- genetic structure in human populations. Using pri…
