Early in mammalian embryonic development, long before the organism's ultimate form has taken shape, a precious subset of its cells are set aside for future use in creating offspring. This task bestows on that subset of cells ...

Female fruit flies can feel when a sexual partner is a good fit. Scientists have long known that proteins in a male fly's ejaculate make female flies temporarily lose interest in other partners. It's a trick male flies use ...

Birds do it. Bees do it. Plants do it, too. And for good reason: Sexual reproduction has evolved as nature's way of shuffling the genetic deck of cards, so to speak. That shuffling actually starts before organisms make sex ...

The highly unusual "semi-identical" Australian twins reported last week are the result of a rare event. It's thought the brother and sister (who have identical genes from their mother but not their father) developed from ...

Evolutionary interests of males and females do not always coincide. This is known as sexual conflict: male innovations that allow them to reproduce more sometimes hurt females, and vice versa.
