Black people

Thats somewhat of the theory I thought of .

 

The question is not how did black people get black but how did white people get white. Human life evolved in Africa. Your ancestors, far enough back, were black.

As to how white people got white, humans synthesize a vital nutrient called Vitamin D from sunlight through their skin. As darker skinned people moved out of Africa for whatever reason, they ended up finding places with gloomy, sunless climates (think of an African travelling from Africa to, say, Scotland). Now, in such a climate they would be unable to synthesize Vitamin D properly as their skin, being dark, blocks most of the sunlight out. So, offspring of these black people who happen to have lighter skin tones did better in these climates because they got more Vitamin D and were more healthy. Since they did better, their genes got into the next generation more than their darker-skinned counterparts' genes did. Thus our ancestral origins split into different 'races' dependent on their environment.

As an interesting aside, it was found that black people in the United States were often Vitamin D deficient (especially in gloomy cities like Chicago) because this was obviously not the environment to which evolution had adapted them. For this reason, Vitamin D is a supplement found in milk, among other things.

 

haha i never really thought of it that way...! i love it! it honestly does make sense though 0_o maybe thats why they have white (or less colored) hands and feet? as they werent exposed to the sun so they developed that characteristic over many years.

 

Humans' palms of their hands and soles of their feet never needed pigmentation in any environment (how often do the bottoms of your feet see the light of day?) so we never evolved pigmentation mechanisms in those parts. Every adaptation is costly, even if only slightly. If you want proof of the fact that this affects all people and not just black people, try to tan the bottom of your feet this summer

 

Yeah there could be.... if we were all "created from the cosmic dust".

In all likelihood, ancestral humans were up well before the crack of dawn. Besides which they slept in shelter (huts, etc.) so sun wasn't an issue when they slept any more than its an issue when you sleep.

Think what you may but empirical evidence indicates that it is the case. Humans and great apes evolved from a common ancestor, and the great apes still live in Africa. And lets not forget about a little thing called the fossil record...

They are not their ancestors, though... these are forces that caused slow and constant changes over a period of millions of years. Skin colour is a polygenic trait (except albinism which is just a total lack of pigment and very different from just being a white person). Since it is polygenic, there are many genes at play, and the likelihood of all of those genes being mutated in one generation to form a black baby from white parents is inconceivably small.

I'm sure there've been some white women with white husbands who have had black babies, but I can think of other reasons for it

 

I believe it is melanin not vitamin D that makes ur skin dark.

Just looked up some info on vitamin d. Basically it is produced when light hits your skin, but melanin is the main determinant in ones skin color.

 

I dont think this is limited to building a hut, any form of shelter such as caves would suffice, trees for shade etc.... any being on this planet will take shelter from an enviroment that they do not feel comfortable in, and at night, apart from nocternal creatures, nearly every mammal takes shelter to sleep as its an instinct to protect one self at their most vulnerable.

I have heard of a few instances of this, one instance I remember is a white couple has twins, they were black albinos, blonde hair etc... it was a few years ago but I remember thinking, damn, cus the bloke in that situation would be like, what the hell you been doing women? and she would be like, nothing and then its like, what to believe! but anyways, it has occured, just very rare!

As for why are some white, some black some tanned etc... I believe its all to do with the enviroment, I dont know where the first humans evolved, I dont know whether they were black or white, I just assume they would be too hairy still to tell lol. Its like why do chinese people have slanted eyes? why? WHY? why do people have different coloured hair even? I mean its not like you see a blonde ape, or a ginger ape(unless its an orangatang) well hopefully you know what I mean....I blame the enviroment for how each of us are, and how we as humans adapted to the enviroment in the different areas we are from, as the world remained seperated from each other for so many millions of years, we would have developed to match out situations and im repeating myself now so I will stop.

 

You are correct, and I never claimed it to be anything otherwise. But the affect of melanin making your skin dark is that it alters the amount of Vitamin D you can synthesize. If we didn't need to get Vitamin D in this way, then nature would never have selected for lighter skin in cloudy regions.

Black and white people are of a similar size because there is very little genetic difference between them (skin colour, hair, a little bit of bone and face structure, and that's about it). The great apes (not all of which are bigger than humans) are different sizes than us because we diverged from a common ancestor further back.

Ok to put the bottom of foot thing to rest, first of all, our ancestors would have been up by the crack of dawn. Period. If they weren't up by then hunting and gathering berries, they weren't eating. And if they weren't eating, they weren't reproducing. If they weren't reproducing, then they're not our ancestors and thus we couldn't get any of our traits from them. Furthermore, when the sun is just rising in the morning and just setting in the evening the light is far less intense. When was the last time you got a sunburn at 9:00 AM or 9:00 PM?

And finally, I think it is safe to assume that our ancestors built or sought shelter of some sort. In the Era of Evolutionary Adaptedness, being exposed at night would basically be a death sentence. Primates are diurnal (i.e. opposite of nocturnal) and have systems of vision that are adapted to this fact (that is to say, they can't see in the dark). Even if they could see in the dark, they are at a severe disadvantage when it comes to predators since they (and by extension we) have no natural defense mechanisms worth mentioning. So to put it bluntly, the ones that were spending the night in shelters were the ones that had babies, which ultimately led to you and I being here today, while the ones that didn't seek shelter are the ones that lined the stomach of cheetahs and other Savannah carnivores.

Man I could go on about this shit all day

 

Many thousands of years ago in Africa people were not white or black but gray and the world's most abundant natural resource were massive pools of liquid chocolate. One day a very curious gray male person was walking along the banks of one of these pools and accidentally fell in, startled he immediately ran back to his village and into his hut where his wife was roasting corn nuts and fried chicken. Terrified upon seeing him she ran to a corner of the hut shaking with fear. After some time he was able to convince her that he was still the same person and she calmed down. Later that night as they lay on their dirt floor some of the chocolate that had coated the man's body came off. It smelled so good his wife took a small piece and ate it. It tasted better than anything she had eaten before. She begged her husband to take her to the pools the next day where she promptly jumped in as well.

Soon all the villagers were dunking themselves in the pools thus creating the first black people. As time went on the application methods have become more advanced. Nowadays babies are spray painted at birth--lucky for me.

Melanin​

Stay green, er um I mean brown, er um I mean black ​

 

It seems I have read this thread too late.

Evolution and Melanin have already been mentioned.

What is incredible is that the globalization of the human community on earth is such that in several hundred years, colour will almost be homogenized (or so it is hypothesized).

 

Indeed. And I have a feeling that it will lean much more toward dark than it will toward light, given that "white" countries are industrialized and have thus slowed down their reproduction, whereas many non-industrialized nations are "dark" and are still experiencing rising populations.

 

I don't know, that isn't exactly a reliable or steady characteristic.

I would agree with you though, not to mention that dark skin is the prevailing phenotype.

There was an article posted about it awhile ago. Something about how humans will exists in 3000 based on the most likely scinario.

It was bizarre, like most people will be 6ft+ and have dark tan skin and will be generally weaker and have less body hair than most modern humans. (As far as I remember reading)

You should give it a search.

 

Even if we generally get weaker (since I'm sure there will be those in the year 3000 who are also stronger than we could even imagine now), if we're averaging that height and what not, I bet there'll be some crazy ass athletes in a thousand years.

 

It makes sense that people would naturally have less muscle in the future because there would be more advanced technology(sp?), therefore less physical work will nede to be done as more of it will be automated/done by machines etc..

 

Don't hold me to that article, it's just a vague summary of an article i read several months ago without too much in-depth consideration.

 

i concur on the weaker part. Evolution is all about the way we consume energy. Adaptation, yes. Adaptation of ones phisical form to get energy of conserve it. If technology progresses as it is the element of physical work is almost eliminated. Having big muscles to do certain tasks would be irrevelant. Althought this may not be genetically lost due to the fact that womens may pick a mate with greater phisique. the human mind would see this as an evolutionary must because u need to find a mate to reproduce. whatever the case i believe we will adapt to our changing environment and muscles wont be in demand as much dont get me wrong we still need them. But think about this if everyone in the year 3939 or whatever is born and has some sort of technology involved into thier everyday life i mean greater than now way greater. We went from kitty hawk to the moon, suposedly, in 60 years so think about 1000+ from now we may very well have our own little hover goat car type of thing from birth to death. How would the body adapt to that? maybe less muscles in arms but more in the finger maybe they get longer and stronger to do electrical tasks faster such as typing you will see humans evolving to computers in time. human type speeeds may exced ludicris limits. timothy leary talked about this too it may get to the point in evolution where we become electrical enteties linda like some sci fi shit where were just a human outlined by an electrical current or some shit call this bizzarre or whatever but with enough evolutionary time it could happen if technology becomes pivital to our lives, which it pretty much is.

 

but the pools of milk chocolate theory does seem to work lol
