Parthenogenesis, asexual reproduction, works in many lower level life forms, but not in humans. Although, human eggs can be activated to undergo cell division by way of parthenogensis, they rarely divide more than a couple of times then stop. In higher animal life, there is something more than genomic DNA that the sperm carries into the fertilized egg; something that promotes a "program" of development. It probably has something to do with DNA fingerprinting.

There is hope that the parthenogeneic activation of humans eggs can be made to develop to the stage of creating embryonic stem cells, ESCs. If ESCs could be made without the course of fertilization, this would go along way on eliminating obstacles to that line of ESC research.

Parthenogenesis is the process of asexual reproduction. I've never heard of it occuring in animals higher on the evolutionary pyramid than fish or reptiles.

There once was a science fiction story about an all-female society that emerged. They reproduced asexually by fusing the genetic material from two ova under lab conditions. Given the absence of male Y chromosones, all offspring were girls.

Actually domesticated turkeys can do parthenogenesis as well. They are a bit higher on the evolutionary scale, although they are dumber than either snakes or fish.

As far as I know, it isn't.
