(Phys.org) —A small team of researchers with the University of Ulm's Institute of Experimental Ecology in Germany has found an evolutionary explanation for same-sex sexual behavior (SSB) in burying beetles. In their paper published in the journal Biology Letters, the team describes how they tested what is known as Reeve's acceptance threshold theory in male beetles and found that the evolutionary cost of possibly rejecting females was overridden when there were few of them to choose from.
