If humans live for 50,000 or more years .
If all humans are derived from Africans .
Those who lived near mediterranean became brick red in skin , green eyed , red haired .
Those who lived in Tibet became tibetan and chinese .
But now europeans don't bath in mediterranean water , so they cannot make their hair orange for long , maybe .
Cannot make their eyes green for long .
Because the water they bath in , has no sulphide .
Maybe they will evolve in 10,000 years to have black hair "Again" like when they had when they lived in Africa .
And as Chinese live in flats than highland , maybe their eyes will become normal in 10,000 years or 15,000 years as well .
Not know what will they become in future , but in today's time we know that europeans don't bath in Sulphides , and chinese don't live in highlands .
Skin is also an organ , if you don't give it sulphur for thousands of years as well , it may not retain the sulphur Gene as well .
