Asexual Shark Birth

It must be a sign from above. Well, at least that's what some of the good people of Nebraska are thinking, I imagine:

A hammerhead shark has given birth to a pup without having mated. It is the first time that a shark or any other species of fish has been proved to be able to reproduce asexually.

The pup, a bonnethead shark from the hammerhead family of sharks, was born at the Henry Doorly Zoo in Omaha, Nebraska.

The discovery means that of all animal groups, only mammals are unable to reproduce through parthenogenesis.

Researchers from Queen’s University Belfast and the United States were able to show that traces of paternal DNA were absent from the hammerhead pup, Sphyrna tiburo, which was later killed by another fish in the tank.

Asexual reproduction raises conservation concerns, however, because the birth fails to introduce a new genetic mix. Not only did the pup only inherit maternal genes, but the process was thought to be automictic parthenogenesis, in which only some of the mother’s profile is passed on.


Pity they allowed it to be killed. I'm glad mammals can't reproduce asexually. Some people simply shouldn't reproduce at all, let alone by themselves.

On the plus side, i take this as a positive sign from God that we can rape and pillage the entire planet, and scour the entire sea harvesting it of all life...

Well, all life but one of each animal (none mammals that is), because now we know the little bastards can reproduce without a partner! Maybe thats how Noah fit all the lizards and bugs and shit on the ark... he only needed half as much space as those pesky Bible-doubters calculated he would!

HALLELUJAH, PRAISE BE!

Ah, yeah. Good point that makes the maths completely doable. Only needed half the animals... though they'd pretty inbred, and still they would have had every virus since things don't evolve...

Does anyone find it a little odd that of all the places in the world this happened in Nebraska? It's in the middle of the US, no oceans close by. I grew up on the pacific coast and I knew our aquarium was constantly getting new sharks because they were always dying.

This I believe is a wakeup call 2 all cristians, God says to what he wills "Be!" and so shall it be... and that's exactly what He said to Jesus Christ, and so it was. So, that doesnt make him god-Incarnate.
Duhhhh!
