Recovering signals of ghost archaic introgression in African populations
Science Advances, 2020 Multiple West African populations inherited genes from a population that diverged before modern humans and Neanderthals split. While introgression from Neanderthals and Denisovans has been documented in modern humans outside Africa, the contribution of ...

A new species in the major malaria vector complex sheds light on reticulated species evolution [PDF]
, 2019 Complexes of closely related species provide key insights into the rapid and independent evolution of adaptive traits. Here, we described and studied Anopheles fontenillei sp.n., a new species in the Anopheles gambiae complex that we recently discovered ...

Benefit of Introgression Depends on Level of Genetic Trait Variation in Cereal Breeding Programmes
Frontiers in Plant Science, 2022 We investigated the benefit from introgression of external lines into a cereal breeding programme and strategies that accelerated introgression of the favourable alleles while minimising linkage drag using stochastic computer simulation.

Migration-selection balance at multiple loci and selection on dominance and recombination [PDF]
, 2013 A steady influx of a single deleterious multilocus genotype will impose genetic load on the resident population and leave multiple descendants carrying various numbers of the foreign alleles.

The Origin of a New Sex Chromosome by Introgression between Two Stickleback Fishes. [PDF]
, 2019 Introgression is increasingly recognized as a source of genetic diversity that fuels adaptation. Its role in the evolution of sex chromosomes, however, is not well known. Here, we confirm the hypothesis that the Y chromosome in the ninespine stickleback,

Effects of asymmetric nuclear introgression, introgressive mitochondrial sweep, and purifying selection on phylogenetic reconstruction and divergence estimates in the Pacific clade of Locustella warblers. [PDF]
PLoS ONE, 2015 When isolated but reproductively compatible populations expand geographically and meet, simulations predict asymmetric introgression of neutral loci from a local to invading taxon. Genetic introgression may affect phylogenetic reconstruction by obscuring

Detecting adaptive introgression in human evolution using convolutional neural networks
eLife, 2021 Studies in a variety of species have shown evidence for positively selected variants introduced into a population via introgression from another, distantly related population—a process known as adaptive introgression.
