Human speciation: how long would it take?

Beauty is objective faggot. Eat shit.

Once humans start colonizing different planets desu having people growing up in different gravity's will start to show an affect after a few generations

Kek, the ultimate brainlet

>think something is beautiful
>hur dur you are fetishist

Hard to say. Probably at least a few hundred thousand years with absolute isolation.

Try millions. Neanderthals separated from other branches of the homo genus millions of years ago and yet Sapiens was still able to reproduce with em.

Literally exactly what I thought. Good taste user, you're clearly a patrician like me

Well, that's why I put "at least". Humans and neanderthals(we presume) were able to conceive fertile hybrids.

In the case of lion and tiger, some of their offspring are in fact fertile, like some female ligers. This might have been the case with human and neanderthal as well.

To add insult to neanderthal injury, there seems to be no strictly-male neanderthal DNA in modern humans. Basically the neanderthals were cucked hard.

do interracial couples have a higher amount of fertility issues compared to intraracial couples? you'd figure there would be a slight increase of fertility issues over all.

>No, you're just afflicted by exoticism and fetishism
How the fuck do you know where that poster is born?

Quite a long time. Hundreds of thousands of years, assuming ABSOLUTE isolation.

Things might go a LITTLE faster if the isolated population began with a small gene pool. Say, 20-30 people shipwrecked in another star system. Due to local environment factors (gravity, air pressure, temperature, sunlight, etc.) they might LOOK somewhat in only a few thousand years. Possibly within a couple of centuries. But they'd still be inter-fertile if ships came from Earth again.

he wasn't the one who said the chink was "clearly" the hottest

Op here
Beauty is partly subjective. All these girls are models selected by the photographer for their beauty and to represent different representative ethnicities, the best of each in some way.

He's betting that he's a white American or european, makes sense statistically I suppose

100,000 years, blacks are not a different species since they began to exist 87,000 years ago but the San Bushman existed 122,000 years ago making them another species by sheer genetic distance.

>Humans and neanderthals(we presume) were able to conceive fertile hybrids.
Gut feeling says there would be more Neanderthal DNA in our genome if this were so. (Somebody science me.)

Ok but what about THIS?

I'm 8% Neanderthal according to the 23 and me kikes. Like that's more than I'm Scottish and I got a Scottish name.

So, fuck you in the dick with a pencil, then snap the pencil and force feed you liquids for hours on a facebook live stream.

Suppose homo sapiens and neanderthals could not produce fertile offspring. Because of this, all neanderthal-homo sapiens children die without reproducing. That is, homo sapiens and neanderthal DNA cannot intermingle - every "humanoid" is either 100% neanderthal or 100% homo sapiens. Given this, how would you explain the fact that neanderthal DNA is present in a large percentage of homo sapiens dna? So the only logical conclusion is that at least _some_ neanderthal-homo sapiens children were fertile.

Since neanderthals went extinct ~40,000 years ago, and neanderthal DNA is present in large amounts in basically all modern non-sub-saharan humans, it seems like the vast majority of human-neanderthal children were fertile.

Any americans interested in this should try to get to the human origins exhibit in the smithsonian museum of natural history in Washington DC. They have one of the most complete neanderthal skeletons on display, and a ton of really cool info + models

don't want to be so racist, but skin color does make you looks cleaner and seems to be hygenier.

I think the asian girl in the middle and the caucasian in the bottom right smell as good as they look.

Shit taste

How do we determine asexually reproductive organisms are different species using that concept?

What about hybrids that actually manage to produce fertile offspring?

>2nd from right, 5th from bottom
literally stood out amongst all those blondes and redheads
How can others even compete?

Anyone have the names?

I don't think melamin smells so much different ethnicities must smell sightly different, not even counting food effect on body odor that goes beyond garlic

You really need to add another concept to classify correctly
Think about wolfs and dogs, cat and wild cats, polar bears and grizzlies, there's some mixing in these cases and it may be hard to tell the boundaries.
If you consider bacterias gene exchange being something like sex they're into bestiality and necrophilia

The curls on top-left tho

this
Top left>Top middle>Top right=bottom right>bottom left>>>>>>>>>>>>>>>>>>>>>>Bottom middle

Why do they always choose the most hideous, alien looking people to represent whites?
They couldn't have picked an uglier girl if they tried

Thanks for the tip user.
I'm moving to the area soon and I'll have to check it out

The big problem is that beautiful white girls in a way often don't look that much specifically white and also that non white beauties often somewhat look white

truly depends how many years they start to live in a different environment, the offspring might already come a bit changed and ready to adapt the climate
>aka environment adaption

Damn, your yellow fever it's severe... it's the worst

There is a theory called "Punctuated equilibria". To made it's simple the race even if isolated can remain stable for the interbreed without an important ambiental change.

European, Asians and Blacks are all able to adapat with various degree on all the same enviroments, so it's very difficult to start an hard different evolutive path, for sure it's incredible slow in this condition.

Op here, I was also thinking about a sort of artificial constrain like some sort of eugenics. Should nazis continued breeding their aryans, they may have eventually ended with somewhat different humans, selecting the equivalent of animals breeds

So the short answer is can't tell.

Long answer is that it can either get a mutation that renders a person unable to breed with anyone else in a single generation. On the other hand people can breed separately for generations and still come back into society. Humans are really really closely related, it would need a lot of mutation and separation to do this. For nazi Eugenics I don't think it would ever happen, barring 1000+ years of isolation, unless they started irradiating people or some shit.

and the white girl is the hottest, as expected

> (You)
>and the white girl is the hottest, as expected
Likely because you're white but not only; look at this article about ethnoracial preference stats from okcupid
web.archive.org/web/20100118050917/http://www.sphere.com/article/revealing-the-mysteries-of-online-dating-even-the-politically-i/19261774
There's a graphic where everyone seems to prefer whites

Tru.
Low test detected.
All I know is that all these girls should carry my offspring in their wombs.

It can be accelerated.

I heard there was some population that went extinct. The something or rather pygmies. Apparently they were unable to breed with outsiders. I think they were on an island somewhere and disease killed them.

Theyre all attractive

The one with curly hair is the cutest

>-- Jewish men are more compatible than Muslim men with Muslim women.

...

minimum 20 thousand years, maybe 10 times more

Maybe muslim men tend to be douchebags and macho like required by their religion. However being in couple with a non muslim often means to break up with the religious part of your family. Islamists even feel required to kill the apostates who quit islam, and a woman marring a non muslim is quitting islam

One specific element is that most okcupid users are americans so it may not reflect what going on in other countries. But general preference for whites seems to be a thing. It also may be that it may be much easier for whites wanting interracial to find a good mate

I forgot to precise that even if the stats don't say it that the ease for interracial must apply to any gender and sexuality.
Coalburning is bad for the climate but not coalburning like pic related

Realistically, never. Humans are a very large interbreeding population with very low genetic diversity. We have the lowest total genetic diversity of all primates, and it is not clustered in any way.

>if we just keep making threads, it will disprove science!

You can mate with a bushman, so no, they're not a different species.

They all look kind of enervated and somewhat childlike, not just the white girl.
My guess is that the photographer was a bit of a pedo.

ncbi.nlm.nih.gov/pubmed/24032721

Do you happen to know the ethnicity of each girl?
Here's my guesses:
1. Top left: South-America
2. Top middle: Asia
3. Top right: Middle east?
4. Bottom left: African American
5. Bottom middle: African
6. Bottom right: Europe

Also Who does everyone think is the hottest?
Here's mine:

1>6>3>4>2>5

I am white european myself
