Females shut down male-male sperm competition in leafcutter ants
Date:3/18/2010

in a very biodiverse range of organisms, following in the footsteps of people like Bob Silberglied, who asked why butterflies and moths have two kinds of sperm in the 1970's."

Similar sperm competition systems appear to have evolved independently in ants and in bees. Researchers now aim to discover how genes that control sperm recognition in bees and ants may differ, thus continuing to elucidate the details of a process key to reproduction and evolution.
