Abstract
Showing their stripes: The adaptive radiation of East African cichlids has led to more than 1200 species across a number of lakes. Across these species, many convergent traits have emerged, including the presence or absence of horizontal stripes. Kratochwil et al. show that the appearance or loss of stripes is related to changes in the agouti-related peptide 2 gene, which acts as a kind of on-off switch for stripe generation (see the Perspective by Gante). This action has enabled rapid and repeated evolution of stripes across this speciose radiation. Science , this issue p. 457 ; see also p. 396Keywords
