Can we discuss the origins of ethnicity? (Aka another school me thread)

[Tom]

I'm aware of out of Africa theory that a large majority of scientist agree is true, I guess what I'm looking for is a definitive timeline of where we settled and how those conditions in said climate eventually led to changes in our physical appearance. Basically what I'd like is some kind of picture diagram of how things went down so I could have a better understanding.



thanks in advance


Anthropology majors feel free to school us noobs

human beings originated in africa

black with black features

then as people migrated they changed to better suit their environment

and we're here today

How does ones pigment straight up decrease like that though?


And why do asians have slanted eyes, what was it about that part of the world that caused their eyes to turn that way?

 

[Bud Bundy]

they don't like to talk about it but i am sure there were tons of inbreeding when people were first starting out.

obviously


and too keep it completely 100, if u fukking a fine ass bytch u just met the night before that's "technically" inbreeding also.


We all share more in common genetically than any small group of chimpanzees do with each other.

I don't know the facts, but my theory is that all man is pretty much black and white, and anything else is a mix in between. Black being the original, white being the mutation, the various races being different admixtures of the two.

I forgot the name of the documentary I watched on PBS about it but i'll post it when I remember.

Some early people left Africa and arrived South East Asia via India. From that group some groups branched off and went south to Polynesia and another group branched off north through Mongolia and went to western Europe. The group that went to western Europe was cut off from the rest of humanity by an ice age and therefore developed white features. Thats a very simple summary of what I remember.

San people of Southern Africa are one of the first people to branch off from "Eve" according to DNA evidence and if you look at their features they are a mixture of different ethnic groupings from throughout the world.

It's all adaptation. Dark Skin is good for tropical climates to protect from Ultraviolet radiation coming from the Sun. Light Skin is better for colder areas.

black people been making it to cold climates for centuries, maybe even milleniums, still black G.

I feel like I'm talking to a 2 year old. It's not like its impossible to survive being black in a cold environment, I'm just telling you why variations in skin color developed.

You're saying the skin color is an evolution of temperature. I thought evolution takes millions of years no? You're saying humans have been around for millions of years? And if we talking adaptation, blacks can survive in the cold, hell, the first person to the North Pole was a black man, so why the need to adapt? I just think the mutations left the continent to settle elsewhere

No. Skin Color is a way to deal with ultraviolet radiation in regards to the production of essential vitamins and compounds.

Evolution of one species into another takes millions of years, not a simple skin color adaptation breh.

You clearly don't understand evolution, natural selection, adaptation or mutation so I'm going to go ahead and save myself some time and not argue any further.

Yes, correct evolution takes millions of years, and adaptation doesn't happen over a short period of time either. This whole pigmentation thing is a dumb argument, as animals of all colors live in all climates. You got Arabian horses in the desert, you got black bears in Canada. How is something an evolution or an adaptation when the only proven origin of white skin is as a mutation of black skin? You're saying blacks moved to the Caucasus mountains, and became white because of the difference in ultraviolet radiation over time? Some parts of science require just as much faith as any religion. Black skinned person can survive in any climate, not as easy for white-skinned people. I say theory because I haven't studied racial orgins enough to give a definitive answer on anything. But seeing as humans haven't lived long enough to have any major adaptations such as skin color change, I am of the opinion that differences in skin colors must have been a mutation (yes, I know all adaptation starts as a mutation) HOWEVER, I don't think the mutation helped a certain species survive in a certain type of environment. I don't think you need to be yellow to survive in the Chinese climate zone I do think a combination of the mutation not allowing certain types to live comfortably in certain areas of the world, along with perhaps some sort of alienation because of their mutation caused the mutants to move out. It's an opinion, if you got facts to prove otherwise, please educate a brotha.

so if u caught up in the red that means ur darkskin?
