There were lots of different ways I could pose this question, but I think I’ll try it this way:
Why is black hair and brown eyes the majority heretical combination for the population of the Earth?
Think about it: Asians, Middle East, Indians(both types),Hispanic, even Africans (a bit different type of hair follicle, but still it fits the criteria)
When you think about it only a small percentage of people have different color eyes or hair differing from the above description and I’d like to know why.
I always learned that certain facial features changed (generationally)to accomodate the person for- ex. longer noses in arrid regions. So for what reason would so many people from so many different parts/climates of the world have black hair and brown eyes?
