Early and late eclosion strains were developed from Drosophila melanogaster cultures. The Oregon-R parent strains (isolated in 1925) showed significantly more selectability than the W2 parent strain collected at the beginning of this study (1971). This is consistent with the hypothesis that the selective advantage of circadian behaviors is reduced in laboratory conditions.
