In a surprising development in marine biology, recurrent parthenogenesis has been documented for the first time in the shark Mustelus mustelus, also known as the common smooth-hound. This discovery, ...

The process is called parthenogenesis, from the Greek words for “virgin” and “birth.” Some plants and insects can do it, as well as some amphibians, reptiles, birds and fish. A stingray ...
