Scientists said on Friday they have genetically engineered female fruit flies that can have offspring without needing a male, marking the first time "virgin birth" has been induced in an animal.
Scientists revealed last month that a female crocodile in a Costa Rican zoo who had never been near a male laid an egg containing a fully formed foetus, the first recorded virgin birth for the reptile. Seeking to find a genetic cause for the phenomenon, Sperling and several US-based researchers decided to experiment on the fruit fly Drosophila melanogaster.
Sperling said that the feat would have been almost impossible to achieve in any other animal because of the wealth of data about fruit flies --Mammals -- including humans -- are not capable of having virgin births anyway because theirBut Sperling said that more animals are probably capable of virgin births than is currently known, pointing to the recent crocodile discovery.
