General theory for stochastic admixture graphs and F-statistics [PDF]
, 2018 We provide a general mathematical framework based on the theory of graphical models to study admixture graphs. Admixture graphs are used to describe the ancestral relationships between past and present populations, allowing for population merges and ...

Genomic insight into the population history of Central Han Chinese
Annals of Human Biology, 2021 Background In recent decades, considerable attention has been paid to exploring the population genetic characteristics of Han Chinese, mainly documenting a north-south genetic substructure.

Laboratory colonisation and genetic bottlenecks in the tsetse fly Glossina pallidipes [PDF]
, 2014 Background The IAEA colony is the only one available for mass rearing of Glossina pallidipes, a vector of human and animal African trypanosomiasis in eastern Africa. This colony is the source for Sterile Insect Technique (SIT) programs in East Africa.

Modelling admixture across language levels to evaluate deep history claims
Journal of Language Evolution, 2022 The so-called ‘Altaic’ languages have been subject of debate for over 200 years. An array of different data sets have been used to investigate the genealogical relationships between them, but the controversy persists. The new data with a high potential for such cases in historical linguistics are structural features, which are sometimes declared to be ...

GENETICS, 2023 Abstract qpAdm is a statistical tool that is often used for testing large sets of alternative admixture models for a target population. Despite its popularity, qpAdm remains untested on 2D stepping stone landscapes and in situations with low prestudy odds (low ratio of true to false models).

Enhanced methods for local ancestry assignment in sequenced admixed individuals. [PDF]
, 2014 Inferring the ancestry at each locus in the genome of recently admixed individuals (e.g., Latino Americans) plays a major role in medical and population genetic inferences, ranging from finding disease-risk loci, to inferring recombination rates, to ...

Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]
, 2020 Polyploidy has played an important role in evolution across the tree of life but it is still unclear how polyploid lineages may persist after their initial formation.

Small Amounts of Archaic Admixture Provide Big Insights into Human History [PDF]
Cell, 2015 Modern humans overlapped in time and space with other hominins, such as Neanderthals and Denisovans, and limited amounts of hybridization occurred. Here, we review recent work that has identified archaic hominin sequence that survives in modern human genomes and what these genomic excavations reveal about human evolutionary history.

Genome-wide and paternal diversity reveal a recent origin of human populations in North Africa. [PDF]
PLoS ONE, 2013 The geostrategic location of North Africa as a crossroad between three continents and as a stepping-stone outside Africa has evoked anthropological and genetic interest in this region.

Admixture in Latin America [PDF]
, 2016 Latin Americans arguably represent the largest recently admixed populations in the world. This reflects a history of massive settlement by immigrants (mostly Europeans and Africans) and their variable admixture with Natives, starting in 1492.
