Eurasian back-migration into Northeast Africa was a complex and multifaceted process.

PLoS ONE, 2023
Recent studies have identified Northeast Africa as an important area for human movements during the Holocene. Eurasian populations have moved back into Northeastern Africa and contributed to the genetic composition of its people. By gathering the largest

Genetic Stratigraphy of Key Demographic Events in Arabia [PDF]

, 2015
The issue of admixture in human populations is normally addressed by genome-wide (GW) studies, and several approaches have been developed to date admixture events [1,2,3,4,5].

Extensive intra- and inter-genetic admixture of Chinese gamecock and other indigenous chicken breeds revealed by genomic data

Poultry Science, 2023
: Genomic admixture is a widespread phenomenon among domestic animal breeds, including chickens. However, reports on admixture within Chinese gamecocks or other indigenous chickens are limited.

MultiWaverX: modeling latent sex-biased admixture history

Briefings in Bioinformatics, 2022
AbstractSex-biased gene flow has been common in the demographic history of modern humans. However, the lack of sophisticated methods for delineating the detailed sex-biased admixture process prevents insights into complex admixture history and thus our understanding of the evolutionary mechanisms of genetic diversity. Here, we present a novel algorithm,

Legofit: estimating population history from genetic data

BMC Bioinformatics, 2019
Background Our current understanding of archaic admixture in humans relies on statistical methods with large biases, whose magnitudes depend on the sizes and separation times of ancestral populations.

Admixture with indigenous people helps local adaptation: admixture-enabled selection in Polynesians

BMC Ecology and Evolution, 2021
Background Homo sapiens have experienced admixture many times in the last few thousand years. To examine how admixture affects local adaptation, we investigated genomes of modern Polynesians, who are shaped through admixture between Austronesian-speaking

The Effect of Recent Admixture on Inference of Ancient Human Population History [PDF]

Genetics, 2010
AbstractDespite the widespread study of genetic variation in admixed human populations, such as African-Americans, there has not been an evaluation of the effects of recent admixture on patterns of polymorphism or inferences about population demography.

Inferring Admixture Histories of Human Populations Using Linkage Disequilibrium [PDF]

Genetics, 2013
Abstract Long-range migrations and the resulting admixtures between populations have been important forces shaping human genetic diversity. Most existing methods for detecting and reconstructing historical admixture events are based on allele frequency divergences or patterns of ancestry segments in chromosomes of admixed individuals. An
