A Shark’s Immaculate Conception

Posted in Uncategorized, WTF?! with tags , , , , , , , on October 11, 2008 by TheDiversePurse

Scientists have confirmed the second case of a “virgin birth” in a shark Friday. The pup, through DNA testing, proved to have no male genetic material. Apparently, scientists have long known that these sorts of births are not a rare occurrence in the animal kingdom. There have been cases of female bony fish, amphibians, reptiles, and birds bearing young without the aid of a male.

Shark scientist and lead author of the second  study Demian Chapman commented, “It is quite possible that this is something female sharks of many species can do on occasion.” Can this help with the declining population of sharks in the wild? “It is very unlikely that a small number of female survivors could build their numbers up quickly by undergoing virgin birth.” Link!
