Why we born with different Color skins?

Well...how do I put this... some of us were burnt.

Explanation:

if this is a serious question I'm pretty sure it's because we evolved from monkies so some of us kept the same skin color and that's why some are white and the other are... ahem cough cough. black

the answer would be roots! roots are the parts of the plant that are underground, and that's how they'd anchor the plant. the stem is above the sol, which doesn't with anchoring. hope this !
