Population history and admixture of the Fulani people from the Sahel

The American Journal of Human Genetics
Summary The Fulani people, one of the most important pastoralist groups in sub-Saharan Africa, are still largely underrepresented in population genomic research. They speak a Niger-Congo language called Fulfulde or Pulaar and live in scattered locations across the Sahel/Savannah Belt, from the Atlantic Ocean to Lake Chad.

Killer whale genomes reveal a complex history of recurrent admixture and vicariance [PDF]

Molecular Ecology, 2019
Abstract Reconstruction of the demographic and evolutionary history of populations assuming a consensus tree-like relationship can mask more complex scenarios, which are prevalent in nature. An emerging genomic toolset, which has been most comprehensively harnessed in the reconstruction of human evolutionary history, enables molecular ...

Modeling Continuous Admixture Using Admixture-Induced Linkage Disequilibrium

, 2017
Recent migrations and inter-ethnic mating of long isolated populations have resulted in genetically admixed populations. To understand the complex population admixture process, which is critical to both evolutionary and medical studies, here we used ...

Reticulate evolution as a management challenge: Patterns of admixture with phylogenetic distance in endemic fishes of western North America

Evolutionary Applications, 2020
Admixture in natural populations is a long‐standing management challenge, with population genomic approaches offering means for adjudication. We now more clearly understand the permeability of species boundaries and the potential of admixture for ...

Evaluation of group genetic ancestry of populations from Philadelphia and Dakar in the context of sex-biased admixture in the Americas. [PDF]

PLoS ONE, 2009
Population history can be reflected in group genetic ancestry, where genomic variation captured by the mitochondrial DNA (mtDNA) and non-recombining portion of the Y chromosome (NRY) can separate female- and male-specific admixture processes.

Admixture in Latin America: geographic structure, phenotypic diversity and self-perception of ancestry based on 7,342 individuals. [PDF]

PLoS Genetics, 2014
The current genetic makeup of Latin America has been shaped by a history of extensive admixture between Africans, Europeans and Native Americans, a process taking place within the context of extensive geographic and social stratification.

Histories of Admixture

, 2022
Les métissages génétiques sont un mécanisme essentiel de l'évolution biologique de nombreuses espèces, dont Homo sapiens. Dans cette Habilitation à Diriger des Recherches, nous étudions les Histoires de Métissages dans les populations humaines, de la théorie de la génétique des populations à l'analyse de données, en passant par l'échantillonnage ...

The genomic footprints of migration: how ancient DNA reveals our history of mobility

Genome Biology
Ancient DNA has emerged as a powerful tool for studying human migration through the detection of admixture signatures. Here, we present the theoretical principles and methodologies for admixture analysis, with an emphasis on f-statistics and qpAdm.

Characterizing the genetic history of admixture across inner Eurasia [PDF]

, 2018
Abstract The indigenous populations of inner Eurasia, a huge geographic region covering the central Eurasian steppe and the northern Eurasian taiga and tundra, harbor 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,

EPAS1 variants in high altitude Tibetan wolves were selectively introgressed into highland dogs [PDF]

PeerJ, 2017
Background Admixture can facilitate adaptation. For example, black wolves have obtained the variant causing black coat color through past hybridization with domestic dogs and have higher fitness than gray colored wolves.
