Zoo celebrates virgin birth of Komodo dragons
Mother never even exposed to males; breakthrough raises scientists’ hopes


MANCHESTER, England - A British zoo announced Wednesday the virgin birth of five Komodo dragons, giving scientists new hope for the captive breeding of the endangered species.

In an evolutionary twist, the newborns’ eight-year-old mother Flora shocked staff at Chester Zoo in northern England when she became pregnant without ever having a male partner or even being exposed to the opposite sex.

“Flora is oblivious to the excitement she has caused but we are delighted to say she is now a mum and dad,” said a delighted Kevin Buley, the zoo’s curator of lower vertebrates and invertebrates.

Evolutionary breakthrough
Other reptile species reproduce asexually in a process known as parthenogenesis. But Flora’s virginal conception, and that of another Komodo dragon earlier this year at the London Zoo, are the first time it has been documented in a Komodo dragon.

The evolutionary breakthrough could have far-reaching consequences for endangered species.

Captive breeding could ensure the survival of the world’s largest lizards, with fewer than 4,000 Komodos left in the wild.

No parthenogensis is known in many reptiles, it is not unusual. I know, I have worked in Chester Zoo.

Just saw this on the news, rushed upstairs to post it, and....curses! I'd been beaten. The babies haven't been named yet, btw. I shall pressure my parents for a trip to Chester Zoo. It's not very far away at all, as we live at the top of the Wirral peninsular and Chester is at the bottom.

And the next person to suggest that this is a heavenly omen gets an e-knuckle sandwich. It is not, it's just a natural phenomenon.

Well if there's a whole species of reptiles out there that has no males and gives birth without them... it stands to reason other reptiles can as well.

Ok I will admit I have never hear of this befor, very interesting. Does this mean that some reptiles share the sexual organs of both male and female. Is this a freak of nature or can all female komodo's do this.

Im pretty sure, correct me if I'm wrong, that the raptors is Jurassic Park didn't reproduce A-sexually, but that some of them changed their sexes to reproduce.

You're right.  Some frogs change sex when there isn't enough of the other.  So if there's to many males, some will become female and vice versa.  And that's why in the story, the dinos did the same thing, since they used frog dna.  Wheither or not that would actually happen in the real world... remains to be seen.

There are a few species of lizards that consist of only females that give birth this way. Its just never been seen in komodo dragons or most other species of reptile. Although most species that reproduce in this way consist of only females.

"Some species of North American whiptails and European lacertid lizards have only female individuals; adult females lay unfertilized eggs that hatch only into females. "








::waits for creationist to hijack thread saying this proves evolution doesnt occur::
