Archaic admixture in human history
Current Opinion in Genetics & Development, 2016Modern humans evolved in Southern or Eastern Africa, and spread from there across the rest of the world. As they expanded across Africa and Eurasia, they encountered other hominin groups. The extent to which modern and 'archaic' human groups interbred is an area of active research, and while we know that modern humans interbred with Neanderthals and ...

Allopatric origins of sympatric brook charr populations: colonization history and admixture
Molecular Ecology, 2005AbstractNatural selection is presumed to be the driving force behind the occurrence of phenotypically and genetically divergent populations in sympatry within many north temperate freshwater fishes. If, however, these populations have different ancestral origins, history could also contribute to their divergence.

Adaptive Genetic Exchange: A Tangled History of Admixture and Evolutionary Innovation
Trends in Ecology & Evolution, 2017Genetic exchange between divergent evolutionary lineages, from introgressive hybridization between locally adapted populations to insertion of retroviral sequences into eukaryotic genomes, has now been documented. The detection of frequent divergence-with-gene-flow contrasts the neo-Darwinian paradigm of largely allopatric diversification. Nevertheless,

The transmission/disequilibrium test: history, subdivision, and admixture.
American journal of human genetics, 1995Disease association with a genetic marker is often taken as a preliminary indication of linkage with disease susceptibility. However, population subdivision and admixture may lead to disease association even in the absence of linkage. In a previous paper, we described a test for linkage (and linkage disequilibrium) between a genetic marker and disease ...

Ashkenazi Anxieties: A Transnational Social History of Jewish Genetic Admixture Modeling, 1971–1986
Journal of the History of Biology, 2022During the late 1970s and early 1980s, population geneticists sought computational solutions to integrate greater numbers of genetic traits into their debates about the ancestral relationships of human groups. At the same time, geneticists' longstanding assumptions about Jewish communities, especially Ashkenazim, were challenged by a series of social ...

Tracing the fine‐scale demographic history and recent admixture in Hmong–Mien speakers
American Journal of Biological AnthropologyAbstractThe linguistic, historical, and subsistent uniqueness of Hmong–Mien (HM) speakers offers a wonderful opportunity to investigate how these factors impact the genetic structure. The genetic differentiation among HM speakers and their population history are not well characterized.
