Summary:[...]on page 108 of this issue, members of the same research group (Hughes et al.3) show that wild guppy males with rare traits obtain more matings and leave more offspring. [...]it seems that the diverse coloration in this species is promoted by both natural and sexual selection. To perturb these stream systems from a possible evolutionary equilibrium in the abundance of different colour patterns, and to enhance the power to detect negative frequency-depend- ent selection, the authors experimentally adjusted the frequencies of different types of males (Fig. 1).
