A genetic history of migration, diversification, and admixture in Asia [PDF]
Human Population Genetics and Genomics, 2022 L.L. Cavalli-Sforza spearheaded early efforts to study the genetic history of humans, recognizing the importance of sampling diverse populations worldwide. He supported research on human evolutionary genetics in Asia, with research on human dispersal into Asia and genetic distances between present-day East Asians in the late 20th century.

Complex population history affects admixture analyses in nine‐spined sticklebacks [PDF]
Molecular Ecology, 2021 Abstract Introgressive hybridization is an important process in evolution but challenging to identify, undermining the efforts to understand its role and significance. On the contrary, many analytical methods assume direct descent from a single common ancestor, and admixture among populations can violate their ...

Complex genetic admixture histories reconstructed with Approximate Bayesian Computations [PDF]
Molecular Ecology Resources, 2019 ABSTRACT Admixture is a fundamental evolutionary process that has influenced genetic patterns in numerous species. Maximum-likelihood approaches based on allele frequencies and linkage-disequilibrium have been extensively used to infer admixture processes from dense genome-wide datasets mostly in human populations ...

Northeast African genomic variation shaped by the continuity of indigenous groups and Eurasian migrations. [PDF]
PLoS Genetics, 2017 Northeast Africa has a long history of human habitation, with fossil-finds from the earliest anatomically modern humans, and housing ancient civilizations.

Geographic patterns of genome admixture in Latin American Mestizos. [PDF]
PLoS Genetics, 2008 The large and diverse population of Latin America is potentially a powerful resource for elucidating the genetic basis of complex traits through admixture mapping.

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.
