Hybrids

[-Demosthenes-]

I saw this one show on the science channel or Discovery about a monkey named Oliver. They thought it might be half human. It that possible?

[Cap'n Refsmmat]

Only if a human mated with a monkey.

[fafalone]

No, it's not possible unless such a creature was genetically engineered. Naturally reproducing the chromosomes simply wouldn't match up.

[Cap'n Refsmmat]

Haven't you seen the Bat Boy in the Weekly World News? :-p
Seriously, even if it was possible, the PETA would try and get it banned. Who knows what would come out?

[psi20]

I believe interspecies mating is possible. I saw an animal planet documentary where hmm i forget, two horse-like animals mated and a hybrid was born. I forget what two species.

[fafalone]

A male horse and a female donkey produce a mule; which is because their species diverged not too long ago. Most (99.999%+) mules are sterile.
However this is a special case and the vast majority of species cannot interbreed.

besides it just aint right

[psi20]

Oh the monkey named Oliver! I remember that monkey. Smart as heck and could walk upright. But then he started attacking someone or something and is now a nobody.

[iglak]

here is a bunch of hybrids (http://www.greenapple.com/~jorp/amzanim/crossesa.htm).


<edit>
i don't know for sure, but i thought mules were actually quite commonly fertile, for hybrids. i thought that about 1 in 30 were fertile.

[fafalone]

1 in 30 seems awefully high... we actually worked out the genetic basis for their infertility and the statistical chance of them being fertile... not so high.

[fafalone]

I'm not sure about a hinny (female horse and male donkey), but I doubt those would be 1/30 either.

like in Horses and Zebra perhaps? or Horses and Donkeys? How about lion and tigers, and false whales/dolphins? When we look at the karyotypes of the different horse varieties there are much larger differences than between humans and chimps. The difference is not so much the magnitude of the differences, but the specificities. Is there anything in the sperm/egg function or the embryological formation of a chimp/human hybrid that would render it inviable?

[-Demosthenes-]

My neighbor, who is a professor, said that it would be possible.

[Cap'n Refsmmat]

Proffesor in what?

[-Demosthenes-]

I don't know, biology or something.

you mean ligers? i seen then on discovery channel
an id love to get a PHD in "or something"

Did he say that, give you stange look and carry on peeling your banana?

Well the biggest obstacle is the different number of chromosomes, particularly since this involves chromosome #2 in humans (aka very large), since chimps lack a compatible second chromosome, it would result in a monosomy; monosomy 2 has never been reported to survive more than a few hours.

[Pinch Paxton]

The monkey wasn't half human in the end, but I think that each species reaches a mutation stage, a stage where the species all suffer from matching gene mutations, at this time in their evolution, they might be able to mate with many similar creatures. We would be required to mate with chimps, but I believe that we will not reach our mutation cycle due to cloning. If it is true that we reach a mutation stage to evolve, then us humans are never going to evolve any further than the point that we have reached now. We are not likely to mate with chimps, so we are not likely to evolve into anything else. This is just another of my wild theories to be ignored.

Pincho.

[psi20]

how do you tell if a species evolves?

[Pinch Paxton]

I guess, based on simularities between species, then a gene comparison.

Monkeys don't peel bananas before eating them. :D

CLONING? Who's cloning?

No, we just mutate when we feel like it, as shown by genetic defects at birth. It's evolution that failed, it came out bad.

[-Demosthenes-]

If it changes, right?

[psi20]

If we just mutate when we feel like it, does that mean that if i continually sky dive, and my children sky dive, and their children sky dive, one day, our family will have bones fragile enough to lift off and fly? :)

oh look:

human--chimp--gorilla--orang utan.

http://www.gate.net/~rwms/hum_ape_chrom_2.gif

I always think that is a great picture.

ok, so the hybrid might not survive very long, but it might still be carried to term though. I have tried looking up monosomy 2 and couldn't find much.

no, Mutations occur in germ line cells, that is, in one of the ovum or sperm that made you. The mutations are random, and then selected for via selective pressures, generally before breeding age.

[Pinch Paxton]

Human,Chimp,Gorilla,Orang utan......are there any more? Also, I doubt that 1 hybrid would cause that. I'm more ready to think of mass mutation. Not evolution for survival, but evolution due to triggered mutation as a cycle of life. Like our genes break down over many generations. All humans carry 5 mutated genes, what if the number rises over time?

[Skye]

Then we get a chromosomal duplication (or part thereof) and we get a bunch of new genes to mess around with. Yay!

[warlord]

Horses and donkeys are further apart genetically than humans and chimps.Humans and chimps are less than 2% dis-similar.Humans and gorillas are just a little more less similar than humans and chimps.A hybrid would be possible.It would have to be a test tube baby.A male ape does it doggy style,it's the only way it knows.A human vagina is thrust more forward than an apes and the human butt makes the vagina even further away.Add to the fact that an ape has a small penis compared to a human.A human male could do an ape doggy style,theoretically,I would think the ape would have to be drugged.All it would take is a mad scientist and we could see a Humanzee,an Orang-Human or a Hurilla.
