I find this more worrying than the economy.

Remember that scene in Jurassic Park where the chaos theorist is talking about how nature will find a way, then the male dinosaurs start inexplicably turning into female... yeah, welcome to Jurassic Ocean. Coming soon - terrifying fish of doom.

heh
i've also recently heard in my evolution psyc class that a population of sharks kept in captivity was discovered to be able to reproduce asexually.
A female shark would give birth to what was essentially a clone.

[Lisheo]

I'd be more worried about the suggestion this might affect humans... Emo kids are already androgynous enough, damnit!

Shark clones? Seriously, we will never conquer the sea.

well.. (and this is gonna be a touchy subject, i'm sure)

isn't one of the theories about origins of homosexual tendencies based on whether the fetus gets the appropriate amount of appropriate hormones?

There's a link about it from that above story:

ah ok
so i'ts not an exact clone, there's a measure of meiosis.

still, interesting stuff.

would that work with human hymafradites too?

[Mentalist]

hemaphrodites are different

they posess both male and female gametes (both egg and sperm)

these sharks only have the female sex cells.

yeah i know but could a hemaphrodite impregnate it's self and would that be imbreeding or just cloning?

[Mentalist]

it wouldn't be cloning, I don't think

the definitinon of cloning, is that the offspring's DNA's identical match to the parent

in case of a hemaphrodyte, you still have your 2 gametes, that presumably have different chromosomes, since their gametes SHOULD undergo meiosis and crossing over just like in regular people.

as long as there's any genetic variation, it's not cloning.

[Cold Iron]

I'm pretty sure hemaphrodytes generally have at least one organ that doesn't function. Would be weird though.

With amphibians, reptiles, birds and bony fish able to do this it makes you wonder what could be acheived in times of stress.

[frookenhauer]

I am grossed out by this thread...Yucky!

This, human hermaphrodites have both organs, but one or both does not function.

No one's going to believe you with confidence like that! But, yes... substantially similar. Plagiarism!

Worms are hermaphrodites. Hermaphrodites can sexually reproduce with themselves or each other, although the resulting level of genetic diversity is reduced when it is self. I don't think there are any functional mammalian hermaphrodites as the reproductive system is too complex.

I think I read about hyenas once, the females can grow a penis or some such...... I don't think it works though, it is just for show for something or other. Do I dare google it to find a relevent link.......?

Wiki to the rescue! They actually all have one and it still works as a female bit including for giving birth. Hyenas are weird, man! I now have a mental image of them being like the egg laying tube of the Queen in Aliens.

I think that exhausts my knowledge of kinkiness in the animal kingdom.

Mezla did not grow up on a farm.

So, female hyena's use their penis as a birthing mechanism? That sounds extraordinarily superfluous. Redundant systems evolution fail.
