The process of speciation (when one species splits into two distinct species that can no longer mate efficiently) takes thousands of years, and the mechanisms underlying speciation are therefore difficult to investigate in the laboratory. In the March 6 Nature, Daniela Delneri and colleagues describe experiments designed to reverse the process of speciation using genomic engineering in yeast (Nature, 421:952-956, March 6, 2003).
