Biologists have long puzzled over why males are necessary for reproduction. New research, published in the journal Nature, reveals that an evolutionary force known as 'sexual selection' improves population genetic health and protects against extinction. To uncover this role of sexual selection, the research team evolved Tribolium flour beetles over 10 years under controlled conditions in the laboratory.
