We challenge the view that our species, Homo sapiens, evolved within a single population
and/or region of Africa. The chronology and physical diversity of Pleistocene human fossils …

Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

Patterson's D, also known as the ABBA‐BABA statistic, and related statistics such as the f4‐
ratio, are commonly used to assess evidence of gene flow between populations or closely …

Genome-scale sequence data have invigorated the study of hybridization and introgression,
particularly in animals. However, outside of a few notable cases, we lack systematic tests for …

The hundreds of cichlid fish species in Lake Malawi constitute the most extensive recent
vertebrate adaptive radiation. Here we characterize its genomic diversity by sequencing 134 …

We present a high-quality genome sequence of a Neanderthal woman from Siberia. We
show that her parents were related at the level of half-siblings and that mating among close …

INTRODUCTION The consensus view on the peopling of the Americas is that ancestors of
modern Native Americans entered the Americas from Siberia via the Bering Land Bridge …

As modern and ancient DNA sequence data from diverse human populations accumulate,
evidence is increasing in support of the existence of beneficial variants acquired from …

Several methods have been proposed to test for introgression across genomes. One method
tests for a genome-wide excess of shared derived alleles between taxa using Patterson's D …

Most speciation events probably occur gradually, without complete and immediate
reproductive isolation, but the full extent of gene flow between diverging species has rarely …
