I wonder what really makes a human look different to each other according to their place of origin. Why peoples in wester countries have a blond hair mostly, tall, fair skin, sharp nose etc. While peoples from the asian countries and far east countries are mostly have average tall, dark hair,dark brown eyes etc. What makes us differ by look here? Is that have to do with the origin or the food we eat. If origin then why it is happen like this? share your thought with me here

I will use the quickest, easiest example that I can think of. The people that are originally from Africa have very dark skin,right? Africa also has a hot climate, therefore over time (evolution) their skin adjusted to the extreme sunlight and because more resistant and protective of the sun, therefore causing it to become darker, more pigment, more protection from sun burns...basically.
