Yeah. The big thing for me was at least getting the point across that black people aren't limited to one color or hair type. That everything in between came from changes in the original Africans. That some of us DO have recessive genes from our African ancestors. That different hair types developed in "us" over time and not only from racial mixing.
I guess you agree on some level. I still don't agree with some things you said, but I'm not going to nitpick over your posting
Well then, it depends mainly due to climatic/environmental conditions.
Evolution occurs when the environment changes dramatically and stays that way FOR A VERY VERY VERY long time.
The African continent is very hot and has stayed that way for a VERY long time; long/stable enough to evolve one hair type/color.
Since the African climate has
not dramatically changed (to "less hot"), and has not stayed dramatic for a long enough period of time, it cannot enable the evolution of various hair types.
So racial mixing is the only probable way for diverse hair types.
Same in Europe. The cold climate there has not dramatically changed (to "less cold") and has not stayed that way for a LONG LONG enough time to enable tighter hair types/darker skin.
So any dark skinned/tight hair type person there, must have been racially mixed.
Since the African environment and the European environment are two EXTREMES, the genetic make-up of their native inhabitants are extreme as well.
eg.
polar bears (white) live in extreme cold and grizzly bears (brown) live in hot areas.
Except through mixing, there are no
NATURALLY OCCURRING GREY/intermediate "prizzly" bears.
