Human-Alien cross breeding? Possible? Implausible?

[companion00b]

Nope

 

[CrystalShadow]

Number of other species humans can interbreed with on this planet = 0

Likelihood of being able to interbreed with an alien species that evolved seperately on a completely different planet = pretty fucking low.

Correction. Number of LIVING species humans can interbreed with = 0.

Some research suggests the Neanderthals didn't actually die out as such. We just interbred with them to the point that they effectively stopped existing as a seperate species.

And as others have pointed out, there are species on this planet similar enough to interbreed.

I don't know how close tigers and lions are genetically, or horses and donkeys for that matter, but it's a fact that they can cross-breed.

1. Why would you want to get freaky with an alien

Who wouldn't?

well it depends they might i giant virus and rape with tentacles

Sorry Murphy, I think there was something amiss in that sentence mate, repeat?

why would breath nitrogen that doesn't make sense ammonia on the other more feasible

It does. Life in a nitrogenic atmosphere with insignificant oxygen content could be possible, if metabolic reactions were to be based on reduction of nutrients rather than oxidation. A model for nitrogen-based life was developed decades ago. For all we know, it is purely hypothetical, but works in theory.

Cheers for that RyQ. To Murphy my statement still stands, if you prefer it then imagine I wrote Ammonia if you've nothing else to add which is constructive. I'm sure you can lurk elsewhere on the forum can't you?


Personal opinion, I'd doubt it myself, after reading the posts of others concerning chromosome structure and count, biological structure and my own idea of implausability.
Cheers for this.

Good point...I should've thought of that.

It is quite possible. It all depends on the DNA of whatever alien species we find. It may not be likely, but it is possible. Even donkeys and horses can cross-breed. The offspring are not fertile, but it can be done.

no it is NOT. if the species are two completely different ones, then there is zero chance.
cross breeds of other species only work because of there relation with each other. ie. a horse is related to a donkey. if you where to substitute a human for a horse you could not have a human / donkey hybrid.

 

[reaper660]

or, maybe you can find a way for everything to produce asexually....that would be weird. Also, what if the aliens are lame? Who would want to be one? What if their entire life cycle takes place within two hours?

But humans and aliens wouldn't even be in the same kingdom.

They would be if they were humanoid aliens... right?

Good point. But if they different genetically they wouldn't. (Which I bet they would be.)

Eubacteria vs Archaebacteria

Are we just considering aliens in the sense of Grays and ETs and such? Just asking.

Because, what if there are humans living on planets elsewhere? They'd still be aliens by definition, and would be able to procreate with Earth humans.

 

[Syndef]

This is all *very* wishful thinking...

You kind of missed my point. I'm saying if the aliens were in fact similar to us in DNA structure, then it would be possible for humans and aliens to inter-breed. I did NOT say anything about humans and horses.

Now where's that link to those scientists who believe Asians to be the off-spring of our ancestors being "visited" by aliens...

O_O

But I'm Asian...

I have nothing against asians but that "report" was seriously the most fun thing i've read all year, a bunch of "scientists" who honestly believe that planet earth was visited by marsians back when we were evolving into the modern man, and cross breading with our ancestors to create asians xD.

 

[Zersy]

1. Why would you want to get freaky with an alien
2. Species can't produce offspring that can reproduce. e.g.the mule and the liger
3. DNA splicing? probably wouldn't work like it does in Sci-Fi films

1. They might tbe really hot
2. we don't kow that about aliens and us yet
3. no idea what that means ?...

 

[Johnnyallstar]

it would require a chromosomal match, else the offspring would be doomed to die. Genetics are VERY precise in how they work.

 

[Drakmorg]

chances humans and aliens could produce offspring "infinity-1:1"
chances those offspring could continue on as a new species "double infinity-1:1"

 

[Ryu2622]

I think it may happen.
Think about it, out of the billions of planets out there, we are the only one with any life on it (that we know of). Why? Because our planet was created with perfect conditions. We are exactly where we need to be, with perfect atmospheric conditions. If any other planet is going to support life, it would have to be very similar to ours, so life on other planets will probably be very similar. Or it could be very different. When you get right down to it, there are millions of things that affect a species evolution. Who knows? Something out there could be very much human, or could be something so fucked up and crazy we won't even be able to classify it. I guess we won't know until we get out there and find out.

 

[a stranger]

congrats on first topic,

anyway, ive been studying aliens in my spare time for almost four years now, theres evidence suggesting that a species similiar to the Dropa mated with evolving apes, and thats where the questionable 'missing link' came in, Becuase with that interbreeding we became a cross between alien and ape.

Thats right. This isnt fact, just a theory being looked into, but I beleive it could be real, and Theres alot of these rumours I dont beleive.

So...maybe...WE are the fucking aliens

...and you found this where?

-words-
It would also be the source of great social stigma (you shagged the lizard-girl!? what the hell were you thinking?).

Well, you can't tell me you wouldn't consider it.
Hell, any human would consider it.
But actually, it might be possible for conception, but after that, who knows.
P.S. Yeah, I did, and I thought it was great, that's what I thought.
P.P.S. When you said "lizard-girl", I immediately thought of The Lusty Argonian Maid, or however it was called. Does that make me messed up?

 

[Aardvark Soup]

Of course not. We can´t even cross-breed with any other species on earth, let alone something from another planet.
