Time dependency of molecular rate estimates and systematic overestimation of recent divergence times.
TLDR
It is invalid to extrapolate molecular rates of change across different evolutionary timescales, which has important consequences for studies of populations, domestication, conservation genetics, and human evolution. Expand
Massive migration from the steppe was a source for Indo-European languages in Europe
We generated genome-wide data from 69 Europeans who lived between 8,000–3,000 years ago by enriching ancient DNA libraries for a target set of almost 400,000 polymorphisms. Enrichment of theseExpand
Genome-wide patterns of selection in 230 ancient Eurasians
TLDR
A genome-wide scan for selection using ancient DNA is reported, capitalizing on the largest ancient DNA data set yet assembled: 230 West Eurasians who lived between 6500 and 300 bc, including 163 with newly reported data. Expand
Worldwide Phylogeography of Wild Boar Reveals Multiple Centers of Pig Domestication
TLDR
Analysis of mitochondrial DNA sequences from 686 wild and domestic pig specimens reveals multiple centers of domestication across Eurasia and that European, rather than Near Eastern, wild boar are the principal source of modern European domestic pigs. Expand
Complete mitochondrial genome sequences of two extinct moas clarify ratite evolution
TLDR
This first molecular view of the break-up of Gondwana provides a new temporal framework for speciation events within other Gondwanan biota and can be used to evaluate competing biogeographical hypotheses. Expand
A Gondwanan origin of passerine birds supported by DNA sequences of the endemic New Zealand wrens
TLDR
It is demonstrated that the endemic New Zealand wrens (Acanthisittidae) are the sister taxon to all other extant passerines, supporting a Gondwanan origin and early radiation of passerines. Expand
Dynamics of Pleistocene Population Extinctions in Beringian Brown Bears
TLDR
Researchers studied genetic change in the brown bear, Ursus arctos, in eastern Beringia over the past 60,000 years using DNA preserved in permafrost remains to investigate the evolutionary impact of climatic and environmental changes associated with the last glaciation. Expand
Rise and Fall of the Beringian Steppe Bison
TLDR
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. Expand
Time‐dependent rates of molecular evolution
TLDR
An overview of the current understanding of time-dependent rates in animals, bacteria and viruses is presented and the challenges in calibrating estimates of molecular rates are described, particularly on the intermediate timescales that are critical for an accurate characterization of time‐dependent rates. Expand
Mitochondrial genomes reveal an explosive radiation of extinct and extant bears near the Miocene-Pliocene boundary
TLDR
Molecular dating of the mtDNA divergence times suggests a rapid radiation of bears in both the Old and New Worlds around 5 million years ago, at the Miocene-Pliocene boundary, which coincides with major global changes, such as the Messinian crisis and the first opening of the Bering Strait, and suggests a global influence of such events on species radiations.
