TL;DR: Overall, it seems clear that there is large variation in both the size of refugia and the duration during which species are confined to them, which has implications for the role ofRefugia in the evolution of species and their genetic diversity.

TL;DR: A detailed genetic history of bison throughout the late Pleistocene and Holocene epochs is reconstructed using ancient DNA and Bayesian techniques to reconstruct a large diverse population living throughout Beringia until around 37,000 years before the present, when the population's genetic diversity began to decline dramatically.

TL;DR: It is argued here that researchers in this field must take a more cognitive and self-critical approach, and in place of checking criteria off lists, researchers must explain, in sufficient enough detail, how the data were obtained, and why they should be believed to be authentic.

TL;DR: Genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans is presented, finding limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and excludes migration as an important mechanism of spread between these two regions.

TL;DR: The genome sequence of a male infant recovered from the Anzick burial site in western Montana is sequenced and it is shown that the gene flow from the Siberian Upper Palaeolithic Mal’ta population into Native American ancestors is also shared by the AnZick-1 individual and thus happened before 12,600 years bp.
