Summary

Numerous genetic analyses show that virtually all traits are accompanied by genetic variance. In a Perspective, Roff explains surprising new findings that reveal a lack of genetic variation in an ecologically important trait (desiccation resistance) in a population of rainforest fruit flies ( Hoffmann et al.). Roff discusses the implications of this study for the adaptation of species to global warming.
