@ima1sthumanonearth8 not even the same gene variations associated with Albanism nor do we consider beneficial traits to be disorders.lighter skin evolved as a response to low vitamin D

@truthseeksme9994 studies on ancient Eurasian populations showing them gradually lose their dark skin supports that dark skinned eventually died out in most places in Eurasia. this isnt because of cold weather this is because of lack of vitamin D. Once farming kicked off modern white skin appeared because a farm diet had less vitamin D, that mixed with low UV light meant disease was from vitamin D deficiency was much more likely. people who suffer from these diseases the most today are also dark skinned. we also see that skin color matches perfectly with UV light exposer across the planet, Modern light skin didn't take off until Farming which is supported by the theory. Also, polar bears have a diet rich in vitamin D, so do Siberian natives since their Diets are also rich in vitamin D. its good to want people to study, but you should do the same and read about evolution.

@truthseeksme9994 Um yeah the studies of ancient Europe and the evolution of light skin constantly refers to it. And it’s not cold weather necessarily it’s the lack of vitamin D. It’s no surprise that those with the most vitamin D deficiency today are people with dark skin, also skin color matches perfectly with UV light exposer across the planet, we also know that dark skin has a harder time absorbing UV light to create vitamin D, which is good for an environment with lots of UV light and vitamin D rich food. Also polar bears have a vitamin D rich diet, why would they need light skin? It’s the exact same for native Siberian’s who also have dark skin than most Europeans because they have a vitamin D rich diet. However they are still light compared to people around the equator, that way they can absorb more UV light through their skin. Im one of those “but the observed fact repeatedly confirmed by scientist say”. You know facts like the sun is the center of the solar system, the earth is round, and the moon isn’t made of cheese.

@truthseeksme9994 again this just isn't true, you have to have a good amount of vitamin D or diseases like rickets form. sunblock is also not needed in most norther environments; it's almost seems like to me that you think white people lather themselves in sunblock before they go outside and for the most part this isn't true. i am aware of the difference however do you not know of the health benefits of animals with similar pigmentation loss? artic fox, artic wolf, artic rabbit, polar bears, certain species of bird. You failed to realize the health benefits of light skin in the environments i mention. the studies are all there on google scholar.

If that’s the case then please explain how dark skinned dies out in Eurasian population. Black skin also absorbs less UV light and therefor produce less vitamin D in low UV environments. Mix this with a low vitamin D diet like with farming and it’s clear to see that dark skin in these environments was a disadvantage leading to the evolution of light skin and the slow decline of dark skin in Eurasia.

@truthseeksme9994 who are these greats? it would only make sense today without modern standards of living. how many dark-skinned people in north climates are living with a lack of vitamin D? not many because they can have a vitamin D rich Diet and even take supplements if they need be. so, their skin color will not change the pressure isn't nearly strong enough. the same is true for light skinned people in hot climates, white people have clothing, sunscreen, housing and accessories to combat these they are also not required to spend nearly as much time outside as our prehistoric ancestors. How many white people are dying of blistering sun burn causing them not to hunt for food or catch prey? not many. So, the pressure is mostly gone it's not strong enough to change skin pigmentation. Pressures have to be strong causing only certain gene variations to be passed on in greater numbers. science is indeed free to practice but it's validated through peer review.

Yes since mass migrations from north east asia and west Asia came into Europe bringing more gene variations associated with lighter skin. By 3,000 bc light skin was dominate. People in Europe at the time were still lighter than their African counterparts since they still had atleast one gene variation associated with light skin making them perhaps 1/3 lighter. Farming is a big reason why. People became lighter once they moved into Eurasia and then became even lighter once farming took off because much of their vitamin D rich diets were replaced with farming diets. A lack of vitamin D is deadly so humans in Eurasia evolved lighter skin to better absorb UV light and therefor synthesis vitamin D.

@jamesgardner6707 Scandinavians became farmers though and Inuits didn’t which is why they remain darker, some studies also show that they synthesize vitamin D better. All the variation between population didn’t exist when humans left Africa though. We all originated from the same population so difference emerged through mutations once we split and moved through Africa and they continuous in the groups that left as well.

@jamesgardner6707 ever since roughly 5,000 bc their main diet is farming. They couldn’t have a large population if all they did was hunt.

That’s just one gene variation, multiple gene variations make up light skin the last of which originated some 6,000-8,000 years ago. But yes humans have been varying levels of dark skinned throughout most of human history.

White skin isn’t any of the gene variations associated with Albanism nor are all the gene variations on genes associated with Albanism. This fact alone prove that what you are saying is false. Mutations are natural, you seem to not understand how evolution works. You understand that mutations do not spread unless beneficial or neutral correct? Light skin being so wide spread proves it’s usefulness. We do not call a beneficial trait a genetic disorder which is exactly why humans aren’t considered to have a baldness disorder.perhaps you can explain how something that helps you survive is bad and also how light skin is unnatural despite evolving naturally. Separate in what way? All human population outside of Africa are genetically closer to each other than they are to Africans. This was a lot of talk to try and justify your obvious racial bias but sadly for you it bares no fruit.you’ll need to try and understand evolution atleast a little bit before you comment on such things.

@pixelander it’s not albinism at all. The op is trying to claim half of the worlds population suffers from a genetic disease. This is false, the op simply doesn’t understand genetics or evolution.
