In a study reported Friday in the Journal of Fish Biology, scientists said DNA testing proved that a pup carried by a female blacktip shark in a Virginia aquarium contained no genetic material from a male.
The first documented case of asexual reproduction, or parthenogenesis, among sharks involved a pup born to a hammerhead at an Omaha, Nebraska, zoo.
"This first case was no fluke," Demian Chapman, a shark scientist and lead author of the second study, said in a statement. "It is quite possible that this is something female sharks of many species can do on occasion." |

A very interesting article. Thanks! Parthenogenesis has yet to receive the study the phenomena deserves.
But I've no doubt that when it's all figured out, the results will show that God done it.
