After Hundreds Of Years, Will Everyone Have The Same Shade?

Will Humans Eventually All Look Like Brazilians? - Yahoo! News

The person that's writing the article assumes that all people from Brazil look alike - they go from blonde haired blue eyed to black as anyone from the Congo.

What is the point they're trying to make? Oh right they have no point its just liberal race mixing propaganda.

"All look like Brazilians?" what a ridiculous statement, in the "real world" this person would be out of the job for even suggesting something so ridiculous.

You dont think after how many ever years people will intereact with each other and bread?

THAT is human. And we will.

If it's a religion thing, well, everyone race is turning to whatever religion anyone chooses. We will all be one at some point, "racially".



I'm just laughing at people thinking their race is special, black or white, its ridiculous.

I expect the Japanese will maintain racial purity.

Brazilians don't have one look. The title of the article is stupid (even without reading the article)

people are dumb and this thread and many of the posts in it are a prime example

I'm from America and I doubt it gets much whiter than me. Skin color first evolved out of climate necessity but its not really as necessary anymore because we can survive. Now its down to breeding. We're not gonna all become the same skin color unless EVERYONE interbreeds and you know some people are racist so thats not gonna happen, at least not now.

there will always exist a colour spectrum of light to dark

its impossible for everyone to be the same colour

I think what you, "prefer what is similar you yourself", can be taken in many ways.

And I don't know how I would feel about this sh1t if I was white. We won't be around for the planet being all close in a darker or medium shade.. but I'm comfortable with the fact that the planet will not be filled with cac's.

The problem with the scenario is that it assumes all these human variations in phenotype were original and distinct, and that their mixture will result in a decrease in variation, but this is actually not true. The opposite is the real truth- all humans are already the product of mixture to different degrees. Furthermore, early humans all mostly looked the same- we got to where we are now specifically because nature tends towards increasing differentiation where there is room for it, and so the amount of variation increased over time, even though the population started out small and homogenous. In short, even if all humans were to mix constantly, there would still be phenotypical variation that would probably be categorized, just with different categories than the ones we use now.

Yes, but earlier on, humans were separated into pockets where the environment allowed different variations to arise. Now? Not so much.

That's a fair point, but my answer would be that not all variations are environmentally-triggered, and that many of them are simply neutral variations (at least in the environment in which they emerge) that occur due to nature's tendency towards variation where there is room for it. Just as the majority of mutations are neutral, many phenotypical variations aren't particularly tailored to anything- they just appear due to mutation, and proliferate because there is no reason for them not to/they weren't sexually selected against.

Well, African people have the most variation. I don't think that the senerio is assuming that a mix will result in a decrease in variation... The Original contains all the genetic code needed to supply adaptive variations when they are needed.

The selective pressures that resulted in the phenotypical variations are not as uncontrolled or important any longer. Neutral genetic drift will cause alleles in the population to tend towards fixation, closer shades, less variation. In Brazil people with dark skin may not have a high percentage of Africa ancestry; so I agree that people will be categorized differently. However, race/skin color is so obvious that any other form of categorization shouldn't be as detrimental.

Are phenotypical variations not tailored to anything- weren't sexually selected against? Most phenotype differences are what organisms use to determine mates and lead to natural selection. no?
