Why the fuck would you assume that twins couldn't have different complexions? WTF is wrong with you?

I don't think you understand what "twins" are. Not all twins are fucking identical dipshit!

>>4790281
calm down, it's one being a faggot and one not that surprised me

>social construct

it's basically proof that different races can have much more in common, genetically, than you would guess by appearances

>>4790273
tl;dr because the article keeps going of faggot tangents describing the faggots' personal lives
...but "twins" do not necessarily require a single ovum and sperm cell, sometimes more than one ovum is present and genetically non-identical zygotes can occur. In other words, the mum fucked so much she had two egg cells fertilized by two different men at the same time. The black guy sounds like a total bro though, would fuck (no homo).

so which of them is the nigger? so I can label him as such and call his race inferior

>>4790294
if the mother didn't fuck two guys, as she claims, are the two brothers the same race?

also, how close together would the two fucks have to be? weeks? days? hours?

>>4790295
Both.

>if the mother didn't fuck two guys, as she claims, are the two brothers the same race?
Considering skin colour is used the most to determine "race" I'd say no.

>also, how close together would the two fucks have to be? weeks? days? hours?
Days/hours (as long as a released embryo can survive). Once the zygote attaches itself to the uterus wall the female excretes hormones that stop new ovums from being released.

define race in any sort of scientific manner

(protip: You can't)

The phenotype of the individual's skin tone.

(protip: Yes I can)

When I get a tan, I change races?
WTF?

DUUUUUURRRRRRRR

I swear to god, the only people more retarded than racists are people like you.

>race = skin tone

Race isn't a biological term. Stop trying to use it like one.

>>4790349

>>4790327

How do you tell apart a Jamaican from an African then?

>>4790342
Yeah, because a tan changes melanin levels that much right? It's physically impossible and you'd die of skin cancer twice over if you try, you dumb fuck insufferable 5th grade.

>>4790359
by skin colour

>>4790359
Ask them

>>4790359
How can you tell a racist from a regular guy.
The racists keeps asking about "race".

>>4790351
We estimate things all the time, nothing in science is 100% accurate, if a form/survey asks you "race" your answer depends on your skin tone.

>>4790353
>Race isn't a biological term. Stop trying to use it like one.
It was until politicians decided it would be to not use that term, start acting like a goddamn scientist and not some closed minded fuckwit with a far left agenda.

>>4790377
it's not a very useful biological term

it's like the softest part of a soft science

>>4790389
True...but we still use newtons equation to build bridges and skyscrapers, we use the ideal gas law on non-ideal gasses because we're too fucking lazy to use an EOS, the same thing with race; we generalize because it's easier than describing groups of individuals using their entire genotype

>>4790377
No, you're wrong.
Even the classification of dogs into breeds has little biological justification. The inter-breed diversity between breeds of dogs is several factors larger than between different races of humans.
>But niggers are clearly different from us.
I never said that it's impossible to classify humans into races, I simply stated that there is no biological justification. There is not a single gene that appears only in one race and not in another. For each genetic seperation, there will be people who are clearly of a certain race that will be classified as another race.
This is not true for different species (obviously) or different sub-species.

>>4790377

>race was a biological term until liberals existed

Liberals have always existed. Race stopped being used when we realized that it doesn't work. Your paranoid politics aside. Since when does being a scientist mean thinking in terms of politics? You want to use an antiquated term so the "liberals" don't win?

>>4790428

>it's easier though

It's easier to not do science at all and pray to a magical sky fairy. It's easier not to think about hard things and question ourselves.

Being a moron isn't justified because engineers don't take into account quantum physics when the make a bridge.

>>4790430There is not a single gene that appears only in one race and not in another
see>>4790428
"Race" is by no means a rigorous term, all I said is that if we must put an individual into a racial category, then skin tone is the best estimation and the one most often used.

>>4790377
>>4790377
>if a form/survey asks you "race" your answer depends on your skin tone

So very tan people of western european decent should put "black"? "Negro"?

And very light skinned people of african decent should put "white"?

U Trolling?

They're both black, the only difference is that the left one stayed more under the sun

>>4790447
>if we must put an individual...
We mustn't.

Let's say Dad is 1/2 European and 1/2 African, like Obama.
Let's say Mom is 1/2 European and 1/2 African too.
Then ON AVERAGE, a kid of Mom and Dad will have 1/2 European genes and 1/2 African genes.
However, that's just on average. There is a good chance that the kid will have 3/8 European and 5/8 African, or 3/8 African and 5/8 European... just depends on random choice of which base pairs end up in the DNA. There's even a very very small chance that the kid will end up with 100% African or 100% European DNA.
In other words, there is a good chance that the kid will look MORE African than EITHER parent, or MORE European than EITHER parent.
So, if both parents could pass for either African or European, and they have fraternal twins, then there is a chance that one of the twins will look more African and the other twin more European.
Hakuna matata.

They are both black, the one on the right is pale because of cancer.

>It's easier to not do science at all and pray to a magical sky fairy. It's easier not to think about hard things and question ourselves.
Define "easier", I find it very hard to force myself to work less accurate, but it's necessary.

>Being a moron isn't justified because engineers don't take into account quantum physics when the make a bridge.
Right mate, why don't you go ahead spend the rest of your life solving elementary problems from the most fundamental level possible. I don't know what perfect little world you live in, but in mine society pays me to produce results as fast as possible, defining race based on skin tone isn't just easier, it's the most practical solution.

>>4790449
>>4790453
You keep saying tan like it's some magical phenomena that completely changes your melanin level, if you would only leave your basement good sir, I think you would find that this is not the case.

>>4790456

Asked me a question, I answered, you faggots are still arguing about it.

You're not smarter or more efficient or any of that shit. You're just rationalizing being a dick. Get over yourself.

I love people who think they're way smarter than they really are.

>>4790482
>You're not smarter
I never said/implied/claimed that.
>or more efficient or any of that shit.
I did imply that, it also happens to be true, are you somehow implying it's not more efficient to find solutions in science and engineering faster by using generalizations? That would also mean rounding off irrational numbers btw.
>You're just rationalizing being a dick. Get over yourself.
No I'm justifying the use of dated scientific term by citing examples other of outdated science being used in conjunction with modern science, this wasn't personal you over emotional leftie faggot.

Nice work generalizing the entire board just now.

They are both mulattos, you can distinctly tell in both of them.

Neither is white, nor black, but something else. Not that I have something against multi-racials.

Cool job generalizing my post.
