    To me it only makes that we're all originally Black - but somehow due to albino mutatution, some became White. Due to mating and selection with those of albino, the "white" race came about.

    Dwayne Rabon: Most all of what you have said seems like Afro-Centrist propaganda. I assume you are Black.

    Whites did not evolve from an albino mutation in Blacks. If this had happened, they would still have the same facial features as Blacks. Whites are not "albino" either. An albino is someone with non-functioning melanocytes. Whites have functioning melanocytes. Whites are "white" because their melanocytes produce more of the reddish/blond pigment phaeomelanin. Blacks and most all other races are pigmented predominately with eumelanin.

    Also, the Sámi are not descended from Eskimos (Inuit). They are descended (most likely) from the same stock as those from Siberia. The Sámi have never occupied England or Ireland.

    Redheads are not a different race then blonds.

    The Welsh do not have red hair. The majority of Welsh have dark, curly hair and brown eyes. The Welsh are descended from the Iberian peninsula (Spain, Portugal).


    If you wish I can get technical and debunk what you have said.
     
  8. ...em, small sidebar but the majority of Welsh have dark straight hair and the predominant eye colour is blue.

    They also put gravey on their chips if that's any help....

    I just saw an young black lady come out of a gas station. She looked just like (a clone!) the sister of a guy that I went to school with. They were of the fisherman caste in India. Legend has it that these people were there before the Aryans came to India. So, I think except for a few really cold climates, people have been travelling for thousands of years. They just found lots of dinosaur bones in Gobi desert in Mongolia. Which means that was a tropical climate 70 to 80 million years ago. I wonder if there were humans then....
     
  17. Ah, Mongolia... best place in the world to find Raptors. Y'know, a few years back, they actually managed to pull out the fossil of a Raptor and its prey preserved for eternity locked in mortal combat...

    Fascinating creatures, bugger all like in the Spielberg films, but hey. It's show business, right?

    Lamentably. no. No humans that far back. There weren't even any hominids, let alone primates and about 15 - 20 million years later a ruddy big rock would take out the lot and amongst the ashes leave behind a tiny shrew-like creature which would eventually repopulate the earth with mammals at the top of the food chain...

    But indeed, once man started with the wandering, frankly they've never, ever stopped. Hence the great cultural and ethic diversity of today and all that really, really good Chinese food 24/7 that goes with it.

    Well, you have been defining Redhaired peoples as a separate race. I do not agree with you on this. Black, Brown, Red, or Blond -- people exhibiting any of these wide variety of traits can still be members of the same race/subrace.


    One of your major errors is your assertion that Redheads evolved from a group of albinos from an African population. You distinguish Redheads from "other" Caucasians by saying that while Redheads are African albinos, other Caucasians come from the Black Sea Basin / North Caucasus Mountains.

    First, African albinos look African. They have African facial features and build. Only their pigmentation is different. Some African albinos:

    As you can see, they don't look like redheads.


    Now let me explain the genetics of human pigmentation. Human skin, eyes, and hair is pigmented by a chemical called melanin. There are three types of melanin: eumelanin (dark brown in color), phaeomelanin (yellowish in color), and neuromelanin (black in color). (We can ignore neuromelanin, because it only pigments the substantia nigra and locus caeruleus of the human brain and the inner ear -- hence the "neuro" before melanin.)

    Melanin is released through cells called melanocytes. Africans have the most naturally (unstimulated) active melanocytes which release so much pigment that their skin results in a dark color. Whites have no natural (unstimulated) melanocyte activity. Instead, their melanocytes are only activated with exposure to UV rays from sunlight. That is why Whites tan when exposed to the sun. Melanin helps filter UV rays, preventing too much exposure. Africans live in very hot and sunny environments; Whites live in comparatively much dimmer and cooler environments.

    Human skin and hair is pigmented with either phaeomelanin (yellowish) or eumelanin (dark brown). Africans have very high eumelanin levels, and very low phaeomelanin levels. Blond Whites have very high phaeomelanin levels, and very low eumelanin levels. Redhaired Whites have about the same melanin levels as Blonds, but because their hair is much thicker so it takes on the color red instead of blond/yellow. Brown-haired Whites have a more or less even distribution of phaeo- and eu- melanin pigments. If their distribution leans more towards the eumelanin side, they will have brown hair of a darker shade. And vice versa. Arabs, Southern Europeans, Africans, and Asians are pigmented predominately with eumelanin. This accounts for their dark hair. The reason Africans, Asians, and Southern Europeans are all pigmented with eumelanin, yet have different skin colors has to do with how active their melanocytes are. As I mentioned earlier, White's (but this can also apply to Asians also) melanocytes only react to UV rays, but Blacks are born naturally with highly productive melanocytes. Arabs are more-or-less tanned Whites. Redheads are somewhat unique when it comes to skin color. Redhead's skin is pigmented with phaeomelanin, and that is why they have an inability to tan (they just burn, no tanning), freckles, and naturally very fair skin.

    Eye color is determined by the amount of melanin they contain (I guess they are pigmented by eumelanin only), among other factors like structure and tissue amounts. Blue eyes do not contain any melanin at all. Unlike in rodents and other animals, human eyes without melanin appear blue and not pink. This can be likened to the color of the sky. The sky appears blue not because air is blue, but because it reflects blue off particles in the air. Obviously, high eumelanin levels result in dark brown or black eyes. Lower levels of eumelanin result in medium brown, light brown, hazel, green, etc.

    So what does this have to do with anything? I am trying to show that Redheads and Blonds are not albinos. They are just pigmented predominately with phaeomelanin instead of eumelanin. (The only albino affinity Whites share are blue eyes.)

    An albino is someone with defective melanocytes. This means their bodies produce no melanin at all.

    Also, Redheads are not a different race from Blonds and Brunets. All three are Caucasian, and can occupy the same subrace (like Nordic, Alpine, Mediterranean, etc.). It is a mistake to list Redheads as a separate race.



    You have also said that Redheads were once much more common in Western Europe. I have heard this before. Not all historians, I have heard, agree upon this, however. But I will entertain the idea anyway. I will just pretend that Western Europe was once Redhaired. So what made Redhair disappear in this region? Because Redheads are really just Blonds with hair of thicker width, it is possible that breeding with Southern Europeans (who have thinner hair) could cause people who would otherwise have Redhair to be Blond. But this is just conjecture and it is unlikely in my mind that breeding with Southern Europeans and Germanics was ever widespread enough to cause this. Besides, the rules of genetics say that thicker hair should be dominant over thinner hair. I would like to see sources which say Western Europe once had a high percentage of redhair.



    You also say that the Eskimos once occupied England and Ireland. I have never heard this before anywhere, and very curious very you get this information. I don't give it any credence at all. For multiple reasons. First, the Eskimos are the Inuit. It seems unlikely to me that the Inuit could kayak all the way to Ireland (and from Ireland to England). Second, if the Inuit did somehow make migrations to Ireland, how come they never made it to Iceland? Iceland is not far off the coast of Greenland, much closer than Ireland is. The first people to colonize Iceland were the Irish, who encountered no other people there. Iceland was a deserted, untouched island before the Irish discovered it. Third, if the Eskimos/Inuit did once occupy England and Ireland, we can expect to find remnant populations. There are none.

    You use the term "Eskimos." Strictly, the Eskimos are the Inuit of the far north of North America (northern Canada, Greenland). Maybe you could have confused them with the Saami, another Mongoloid (racially Asian) arctic people who occupy the far north of Europe (northern Scandinavia and Russia). It is my understanding that the original Saami were the same people as the indigenous Siberians. Also, it is highly unlikely the Saami ever made it to England or Ireland either, and for the same reasons.



    Your history is also very wrong. First off, I have never heard that the Vikings murdered a bunch of Redheads pushing them into Wales (the Welsh are not Redheaded, by the way...). (I would be interested in your sources on this.) On the contrary, some Vikings had redhair themselves. Ever hear of Erik the Red? Also, Russia was founded by Vikings. Russia is named after the tribe "Rus," which most people believe means "red." For your information, the areas with the highest percentage of Redheads are Scotland (~15%) and Ireland (~8%[?]), not Wales.



    Hmm, am I missing anything?
