DNA testing has now proven that a pup carried by a female blacktip shark in a Virginia aquarium contained no genetic material from a male.
The research was reported in Friday's Journal of Fish Biology and marks the first verified case of asexual development in this lineage.

Apparently no one else seems to find this exciting (ie - no comments), but I think this is really interesting. It leads to all sorts of questions on how the mechanics of asexual reproduction work in sharks and what the drivers are, and I wonder what the reprocussions could be for stem cell research.

I think this is very interesting, I wonder what will happen to the shark later in life (i.e. decrease/increase life span?) or how comparable this type of animal will be to the wild ones.
