From CNN:

Scientists have confirmed the second case of a “virgin birth” in a shark.

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.

Increasingly it seems nature is proclaiming that virgin births do not require supernatural intervention.  To wit:

Virgin birth has been proven in some bony fish, amphibians, reptiles and birds, and has been suspected among sharks in the wild.

I wonder how long it will take Christianity to proclaim nature as a heretic for this apparent unorthodoxy.
