:whoa:
they "developed" or had a mutation that was more beneficial? Your argument is that an african can move north and turn white?

I thought it was a "beneficial mutations" or some shyt like that?

It might be a semantic thing but i think it's important to continue to make that distinction no?

it doesn't have to be a "mutation". especially with something like skin color, that can change gradually over time. genetic variation is going to lead offspring to have slightly different skin colors. then nature 'selects' those that best fit the current environment

Its not that unbelievable that the low sunlight in the northern latitudes would be far more beneficial to the lighter skinned offspring especially knowing that vitamin D deficiency causes poor bone growth ,mental health problems and ricketts over many generations there would be a significant impact.

And I don't know if it's just me placing the connotation on the word, but whenever I see folks use the word "mutation" around here they're usually attempting to use it in a negative way, as if white people are "mutants" because of their skin color. Not implying that Brown pride was using it in that manner but I've seen other less educated folks using it in that way lately.

it's a common misunderstanding about evolution that it's all about "mutations"

I think the fox experiment does a good job of showing how the removal of pressures can lead to a lot of natural variation

You seem really hung up on the term "mutation" @daze23 , you shouldn't take it personally.

In terms of time how many generations in a human would you expect to see a black family turn white? Fyi im not trolling just curiois.

this pretty much explains everything

"When the ancestors of modern man separated from apes, they were covered in hair. Little UV light reached their skin and as a result, anthropologists believe they were fair skinned. As modern humans evolved however, their body hair became finer and thinner, leaving their skin more exposed to the equatorial sun. To adapt, thier bodies produced more melanin to protect them from damaging UV rays. Increased melanin made their skin become darker.

As early humans started migrating north into Europe and east into Asia, they were exposed to different amounts of sun. Those who went north found their dark skin worked against them–preventing them from absorbing enough sunlight to create vitamin D. To adapt, these humans started producing less melanin."

So you're saying the original human being was black to say what exactly?

:whistle:
:whistle::whistle:

The leading theory is that skin color adapts to intense sunlight irradiation to provide partial protection against the ultraviolet fraction that produces damage and thus mutations in the DNA of the skin cells.


natural selection produced a color on humans that made them naturally less fertile, with weaker bones, not able to scavenge for free radicals, more difficult to deal with the environment and sun, looking worse on average when aging, certain cancers, NTM there many things that are negatively effected by a melanin deficiency.

Plus http://en.wikipedia.org/wiki/Pineal_gland#Function

http://book.neurosurgeon.org/?defaultarticle=&defaultnode=2150&layout=22 - basic science.

Anthropologists have studied the racial and geographical variations in human anatomy very extensively. Unfortunately, neurosurgeons have not paid much attention to the racial or ethnic differences in neuroanatomy
Racial differences have been noted in the rate of pineal calcification as seen in plain skull radiographs.


There is soooo much that I'm leaving out because I don't want to search all around the internet, but you get the point.
Point isn't that it was a bad mutation, but that it was a mutation that had physical, including neurological (brain) differences. History and science show that some of those genetic variations were negative to say the least.

one could only guess at the answer to that question. there was also a migration that happened over time. it's not like hominids from Africa just found themselves in northern Europe one day

Portal 2 is on sale this weekend btw

No. You're incorrect. Can you all not fukking read? Me and Daze have explained this in like 8 separate posts, having to re-iterate it so you dunces can comprehend. It's about fukking Vitamin D. Melanin doesn't make you immune from UV damage.

do you have a link to your leading theory?
