TL;DR: It is shown by spatially explicit simulations that massive introgression of neutral genes takes place during the invasion of an occupied territory if interbreeding is not severely prevented between the invading and the local species.

TL;DR: It is found that the probability of survival of a new mutation depends to a large degree on its proximity to the edge of the wave, and a consequence of the surfing phenomenon is to increase the rate of evolution of spatially expanding populations.

TL;DR: A simulation study examining the effect of a recent spatial expansion on the pattern of molecular diversity within a deme finds that the shape of the gene genealogies and the overall pattern of diversity within demes depend not only on the age of the expansion but also on the level of gene flow between neighboring demes, as measured by the product Nm.

TL;DR: This study demonstrates a direct genetic link between Mediterranean and Central European early farmers and those of Greece and Anatolia, extending the European Neolithic migratory chain all the way back to southwestern Asia.

TL;DR: How genetic and archaeological information can be integrated to bring new insights to the origins and spread of lactase persistence is illustrated by three simulation studies that have shed light on the evolution of this trait in Europe.
