Greetings Eja
I dont buy the idea that since white people come from the one source, which is Afrika, they are entitled to claim the land of origin.

According to a theory, they became white after migrating to lands with different climates and temperatures. Their body adapted to live in those environments.

That is why they became de-pigmentated because they no longer needed pigmentation for the region they dwelled.

They had long noses to cool the cold air before it reached their lungs.

They have sharper teeth to eat the type of food they at in the region opposed to flatter molars for grinding grains and veggies.

They have stringy hair because of the lack of humidity in the region.

I think we should all stay in the region where we developed these characteristics.

But that is just my opinion. I dont know much about genetics and genetic variation.

This is only from observation and limited research on it.

Peace
