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

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.

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.

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.

Unraveling the genomic diversity and admixture history of captive tigers in the United States. [PDF]

Proc Natl Acad Sci U S A, 2023
Abstract Genomic studies of rare and endangered species have focused broadly on describing diversity patterns and resolving phylogenetic relationships, with the overarching goal of informing conservation efforts. However, few studies have investigated the genomic diversity potentially housed in captive populations ...

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 History of Admixture between Modern Humans and Neandertals [PDF]

The American Journal of Human Genetics, 2015
Recent analyses have found that a substantial amount of the Neandertal genome persists in the genomes of contemporary non-African individuals. East Asians have, on average, higher levels of Neandertal ancestry than do Europeans, which might be due to differences in the efficiency of purifying selection, an additional pulse of introgression into East ...

A General Mechanistic Model for Admixture Histories of Hybrid Populations [PDF]

Genetics, 2011
AbstractAdmixed populations have been used for inferring migrations, detecting natural selection, and finding disease genes. These applications often use a simple statistical model of admixture rather than a modeling perspective that incorporates a more realistic history of the admixture process.

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
