Just like we changed colour of skin

Technically that is not true.

You might have not realised this, but 'white' people are not white (Albino-ism kind of is due to lack of melanin, but thats different and affects 'black' people too). When we go in contact with the sun, the body produces more melanin which is already existing, which makes us darker. Due to being resident in a far more sunnier place, peoples skin contain far more melanin than a place with a lot less sun. There is a slight gene variation on the initial concentrations.

In terms of genetic variation, the difference is a joke. The only real difference is in the mind of people socially programmed as racists.

Edit: On another note, according to some comments in thread, this person shouldn't exist.
