Ancient Admixture in Human History [PDF]

Genetics, 2012
AbstractPopulation mixture is an important process in biology. We present a suite of methods for learning about population mixtures, implemented in a software package called ADMIXTOOLS, that support formal tests for whether mixture occurred and make it possible to infer proportions and dates of mixture.

Genomewide ancestry and divergence patterns from low‐coverage sequencing data reveal a complex history of admixture in wild baboons [PDF]

Molecular Ecology, 2016
Naturally occurring admixture has now been documented in every major primate lineage, suggesting its key role in primate evolutionary history. Active primate hybrid zones can provide valuable insight into this process. Here, we investigate the history of

Adding value to cocoa (Theobroma cacao L.) germplasm information with domestication history and admixture mapping

Theoretical and Applied Genetics, 2007
A sound understanding of crop history can provide the basis for deriving novel genetic information through admixture mapping. We confirmed this, by using characterization data from an international collection of cocoa, collected 25 years ago, and from a ...

Archaic admixture in human history

Current Opinion in Genetics & Development, 2016
Modern 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 ...

Ancestry and admixture of a southernmost Chilean population: The reflection of a migratory history

American Journal of Human Biology, 2021
AbstractObjectivesPunta Arenas is a Chilean city situated on ancestral Aönikenk territory. The city was founded by 19th‐ and 20th‐century colonists from Chile (Chiloé) and Europe (Croatia). This work uses uniparental and ancestry‐informative markers (AIMs) to explore the effects of historic migratory and admixture patterns on the current genetic ...

Small Amounts of Archaic Admixture Provide Big Insights into Human History [PDF]

Cell, 2015
Modern humans overlapped in time and space with other hominins, such as Neanderthals and Denisovans, and limited amounts of hybridization occurred. Here, we review recent work that has identified archaic hominin sequence that survives in modern human genomes and what these genomic excavations reveal about human evolutionary history.

Adaptive Genetic Exchange: A Tangled History of Admixture and Evolutionary Innovation

Trends in Ecology & Evolution, 2017
Genetic 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,

Allopatric origins of sympatric brook charr populations: colonization history and admixture

Molecular Ecology, 2005
AbstractNatural 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.
