Have fruit flies evolved in a lab?

1- Laboratory selection for desiccation resistance, which has been imposed on five replicate populations of Drosophila melanogaster for >200 generations, has resulted in enhanced survivability during periods of extreme water stress. read more

Abstract from: Adaptive Evolution in the Lab: Unique Phenotypes in Fruit Flies Comprise a Fertile Field of Study. 2-Diane Dodd examined the effects of geographic isolation and selection on fruit flies. She took fruit flies from a single population and divided them into separate populations living in different cages to simulate geographic isolation. read more
