Parthenogenesis

Do you know what parthenogenesis means?  I didn’t until I read it in an article that was talking about how a second case of asexual reproduction in sharks was documented this week in Virginia Beach.  It seems that a female blacktip shark, having been the only kind of her species in an aquarium, gave birth without benefit of having a mate.  The article also mentions that last year a hammerhead shark in a zoo in Omaha also gave birth without benefit of mating.

I found this to be quite fascinating!  I knew that there were some animals that could do that, but not sharks!  Considering how many people are afraid of sharks, this could be very scary news to some people.  I would not be surprised to see this story on the Colbert Report’s threat down sometime soon!
