Over centuries of cultivating Saccharomyces cerevisiae to make dough, bakers have put selective pressure on the species, causing it to diverge into two distinct groups, according to the authors.
A museum sample of a 3,000-year-old Egyptian crop plant yields genomic information that helps researchers track the plant’s domestication and migration.
A sequencing study suggests that some genes have evolved in parallel in humans and their canine companions, likely as a result of shared selection pressures.
