Casanova or caveman: Scientists isolate nerve cells that choreograph male fly's courtship behavior
... genes that control sexuality in flies also play a role
in directing human sexuality? "If you look at the basics of fly behavior, you find an innate ability to recognize somebody who is the right species and is the right sex," Baker said. "You tap them and get their attention, you play them a love song an...
