Perhaps that's not actually a requirement for it to be a selective force. I believe humans are perhaps the only species where individuals live well past their fertility age, possibly because grandmothers/fathers helping to take care of their grandchildren offers an advantage. So if you lose your parents due to them contracting skin cancer at an older age, you and your ofspring are at a disadvantage so even in this case it would still be an evolutionary selective force.

But we don't even need to think about grandparents (or aunts and uncles, and other relatives who contribute to reproductive success), if the parents don't survive long enough to see their offspring reach sexual maturity because they got skin cancer and died.

True, dying before reproducing would make it a stronger factor than if it's just the grandparents thing. The only point I was trying to make is that it could still be the major driving force even if it only affects the grandparents, even though it might be a weaker force and the evolution towards darker skin might take a bit longer as a result.

It is because of melanin that makes African children on the whole more intelligent than their European/White, Indian, Chinese and Arab peers.

A study was conducted in Australia in the early 1990’s that tested the ability of Aboriginal, European, Chinese, Indian and Arab children in certain exercises.

The study concluded that after the series of tests, the aboriginal children who are Afrikan by blood and genetics were more intelligent than the Indian, Arab, Chinese and European children and this was due to their high melanin content and the ability of melanin to keep one more in tune with nature and vibration.

Melanin also causes serotonin to flow more effectively in the waking state so to “inexperience” more spirituality. This also helps to keep spiritual attunement at an apex. The less melanin in an individual, the more calcified the pineal gland and less access the individual has to the spiritual world.

This explains why Afrikan/Ghanaian people are a very spiritual people and have a high propensity for the creator/God.
