For those of you who haven't heard this story.

Scientists discover shark 'Immaculate conception'

Scientists have confirmed the second case of a shark "virgin birth" in a new study published in the Journal Of Fish Biology.

DNA testing showed that a pup carried by a female Atlantic blacktip shark contained no genetic material from a male, reports The Associated Press.

The shark was being cared for at the Virginia Aquarium and Marine Science Centre. The finding follows an earlier case of asexual reproduction involving a hammerhead at Omaha Zoo.

Shark scientist and lead author of the study said: "It is quite possible that this is something female sharks of many species can do on occasion."

I am of course gonna take the scientific stance with this, IT'S THE ANTI-CHRIST! Run villagers hide in your homes and pray!:o
 
Shark Jesus is going to get you!!!
 
I want to know how likely this is to occur in mammals. It's been seen in virtually all other vertebrate classes (fish, amphibians, reptiles and birds), but I haven't really heard anything about mammalian parthenogenesis.

I'm gonna pick up this publication for sure. Free access to journal databases FTW!
 
So, sharks can do it. And the Jewish can do it.

Jaws.

Jews.

Honestly... I don't know where I'm going with this.
 
I'm going to chalk this one up to the midichlorines.

Funny, wasn't Zilla asexual in the remake... WHY YES HE WAS!!! AND YOU WOULD KNOW GODZILLA 2000....if that is your true name.

I'll keep the actual science-talk going :up:

I wasn't aware this happens to those vertebrates you listed. Where do the other set of genes come from in those cases?

I was under the impression (and I'm fairly certain) that parthenogenesis results in a clone of the mother...and, as far as I know, the offspring are also always female (well duh if it's a clone).

I've gotta research what processes are involved, though. My guess is that it's a freak occurrence during gametogenesis that results in an already diploid zygote. I'll look it up though for sure.

EDIT: Here's a good site http://articles.gourt.com/en/parthenogenesis

I'm looking at hybridogenesis as the most likely explanation, but that's still just a guess based on what I've just learned.

So....how long before the Romans nail this shark to a cross and stab it with spears and then put it's carcass in a cave with a big rock rolled in front of the entrance? :huh:
