Genomic analysis of 6,000-year-old cultivated grain illuminates the domestication history of barley

Nils Stein, Ehud Weiss, Tzion Fahima, Johannes Krause and colleagues report the genome sequences of 6,000-year-old barley grains obtained from desert caves in Israel. They compare these to whole-exome sequences of a modern barley diversity panel to explore domestication and migration patterns, finding evidence for prehistoric gene flow between wild and cultivated populations.
