North India - evolution or ancestry?

Question

Hi I am North Indian and light brown skinned, most of my caste skin colour is white to light brown but there are a few people in the north with black skin. Do you think The difference of north Indians to the rest of south Asia is an evolutionary trait seen as we have very cold winters or a matter of ancestry ( saka and Aryan). I think its a combination of both??

Answer 1

I just came across you answer i am not indian but i think its maybe that North indians because of the weather and south is more dry, it could also be because of mixing. its the same with european countrys,

Answer 2

its probably just someone from your family was very fair and married some dark indian now your getting mixes.
