Demographic history and admixture dynamics in African Sahelian populations [PDF]

Human Molecular Genetics, 2020
AbstractThe Sahel/Savannah belt of Africa is a contact zone between two subsistence systems (nomadic pastoralism and sedentary farming) and of two groups of populations, namely Eurasians penetrating from northern Africa southwards and sub-Saharan Africans migrating northwards. Because pastoralism is characterized by a high degree of mobility, it leaves

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 ...

The genetic history of admixture across inner Eurasia [PDF]

Nature Ecology & Evolution, 2019
The indigenous populations of inner Eurasia-a huge geographic region covering the central Eurasian steppe and the northern Eurasian taiga and tundra-harbour tremendous diversity in their genes, cultures and languages. In this study, we report novel genome-wide data for 763 individuals from Armenia, Georgia, Kazakhstan, Moldova, Mongolia, Russia ...

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,

Hybridization alters growth and migratory life‐history expression of native trout

Evolutionary Applications, 2021
Human‐mediated hybridization threatens many native species, but the effects of introgressive hybridization on life‐history expression are rarely quantified, especially in vertebrates.

Genetic ancestry, admixture, and population structure in rural Dominica

PLoS ONE, 2021
The Caribbean is a genetically diverse region with heterogeneous admixture compositions influenced by local island ecologies, migrations, colonial conflicts, and demographic histories.

Patterns of admixture and population structure in native populations of Northwest North America. [PDF]

PLoS Genetics, 2014
The initial contact of European populations with indigenous populations of the Americas produced diverse admixture processes across North, Central, and South America.

Genomic insights into the genetic structure and population history of Mongolians in Liaoning Province

Frontiers in Genetics, 2022
The Mongolian population exceeds six million and is the largest population among the Mongolic speakers in China. However, the genetic structure and admixture history of the Mongolians are still unclear due to the limited number of samples and lower ...

Outstanding questions in the study of archaic hominin admixture. [PDF]

PLoS Genetics, 2018
The complete sequencing of archaic and modern human genomes has revolutionized the study of human history and evolution. The application of paleogenomics has answered questions that were beyond the scope of archaeology alone-definitively proving ...

Complex genetic admixture histories reconstructed with Approximate Bayesian Computations [PDF]

Molecular Ecology Resources, 2019
ABSTRACTAdmixture 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.
