Bayesian inference plays an important role in phylogenetics, evolutionary biology, and in
many other branches of science. It provides a principled framework for dealing with …

Although range expansions have occurred recurrently in the history of most species, their
genetic consequences have been little investigated. Theoretical studies show that range …

The past few years have witnessed a revolution in our ability to obtain DNA from ancient
humans. This important new data has added to our knowledge from archaeology and …

Neandertals, the closest evolutionary relatives of present-day humans, lived in large parts of
Europe and western Asia before disappearing 30,000 years ago. We present a draft …

One enduring question in evolutionary biology is the extent of archaic admixture in the
genomes of present-day populations. In this paper, we present a test for ancient admixture …

Comparisons of DNA sequences between Neandertals and present-day humans have
shown that Neandertals share more genetic variants with non-Africans than with Africans …

Hybridization between humans and Neanderthals has resulted in a low level of Neanderthal
ancestry scattered across the genomes of many modern-day humans. After hybridization, on …

A defining feature of species is that their constituting populations are connected by gene
flow. However, interspecific gene flow (introgression) can affect species integrity. If some …

Despite hundreds of reports involving both plants and animals, the mechanisms underlying
introgression remain obscure, even if some form of selection is frequently invoked …

Niche construction is the process by which organisms construct important components of
their local environment in ways that introduce novel selection pressures. Lactase …
