The time and place of European admixture in Ashkenazi Jewish history. [PDF]

PLoS Genetics, 2017
The Ashkenazi Jewish (AJ) population is important in genetics due to its high rate of Mendelian disorders. AJ appeared in Europe in the 10th century, and their ancestry is thought to comprise European (EU) and Middle-Eastern (ME) components.

Ancient DNA reveals admixture history and endogamy in the prehistoric Aegean. [PDF]

Nat Ecol Evol, 2023
AbstractThe Neolithic and Bronze Ages were highly transformative periods for the genetic history of Europe but for the Aegean—a region fundamental to Europe’s prehistory—the biological dimensions of cultural transitions have been elucidated only to a limited extent so far.

Models of archaic admixture and recent history from two-locus statistics.

PLoS Genetics, 2019
We learn about population history and underlying evolutionary biology through patterns of genetic polymorphism. Many approaches to reconstruct evolutionary histories focus on a limited number of informative statistics describing distributions of allele ...

Ancestral Origins and Admixture History of Kazakhs. [PDF]

Mol Biol Evol
Abstract Kazakh people, like many other populations that settled in Central Asia, demonstrate an array of mixed anthropological features of East Eurasian (EEA) and West Eurasian (WEA) populations, indicating a possible scenario of biological admixture between already differentiated EEA and WEA populations.

Reconstructing complex admixture history using a hierarchical model. [PDF]

Brief Bioinform
Abstract Various methods have been proposed to reconstruct admixture histories by analyzing the length of ancestral chromosomal tracts, such as estimating the admixture time and number of admixture events. However, available methods do not explicitly consider the complex admixture structure, which characterizes the joining and mixing ...

AncestryPainter 2.0: Visualizing Ancestry Composition and Admixture History Graph. [PDF]

Genome Biol Evol
AbstractTo effectively depict the results of population genetics studies, it is essential to present ancestry composition and genetic distance. The growing amount of genomic data prompted us to designAncestryPainter1.0, a Perl program to display the ancestry composition of numerous individuals using a rounded graph.

The Complex Admixture History and Recent Southern Origins of Siberian Populations. [PDF]

Mol Biol Evol, 2016
AbstractAlthough Siberia was inhabited by modern humans at an early stage, there is still debate over whether this area remained habitable during the extremely cold period of the Last Glacial Maximum or whether it was subsequently repopulated by peoples with a recent shared ancestry.

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 ...
