A sensory system in the foreleg of the fruit fly that tells male flies whether a potential mate is from a different species has been discovered by scientists. The work addresses a central problem in evolution that is poorly understood: how animals of one species know not to mate with animals of other species. For the common fruit fly iD. melanogaster/i, the answer lies in the chemoreceptor Gr32a, located on sensory neurons on the male fly's foreleg. ...Friday, 28 June 2013
