Abstract

Stick to the Bush Can the underlying genetic changes driving the divergence of populations into new species be predicted or repeated? Soria-Carrasco et al. (p. 738 ) investigated the genetic changes observed after one generation when stick insect ( Timema cristinae ) populations were transplanted from their preferred host plants to alternative hosts. Diverged genetic regions were relatively small, with most loci showing divergence in a single population pair. However, the number of loci showing parallel divergence was greater than expected by chance. Thus, selection can drive parallel phenotypic evolution via parallel genetic changes.
