Birds-of-paradise genomes target sexual selection

Researchers provide genome sequences for 5 birds-of-paradise species: 3 without previous genome data and 2 with improved data. Birds-of-paradise are classic examples of extreme sexual selection due to generations of females choosing mates based on ‘attractiveness’. The result is unparalleled species radiation with males exhibiting vast differences in behavior and an array of exotic feathers. Analyses identified genes potentially involved in feather characteristics, and the sequences will serve as a rich resource for evolution studies. …read more
