BACKGROUND
Recent analyses of de novo DNA mutations in modern humans have suggested a nuclear substitution rate that is approximately half that of previous estimates based on fossil calibration. This… Expand

Vascular plant communities of a polar oasis at Alexandra Fiord (79° N), Ellesmere Island, Canada
- M. Muc, B. Freedman, J. Svoboda
- Biology

A total of 41 stands was sampled for species composition and 29 of these stands for plant standing crop and net annual production at 7 sites on 6 arctic islands. Fourteen additional sites on 10… Expand
Pleistocene Mitochondrial Genomes Suggest a Single Major Dispersal of Non-Africans and a Late Glacial Population Turnover in Europe
- C. Posth, Gabriel Renaud, +32 authors J. Krause
- Biology, Medicine
- Current Biology
- 21 March 2016
How modern humans dispersed into Eurasia and Australasia, including the number of separate expansions and their timings, is highly debated [1, 2]. Two categories of models are proposed for the… Expand
