Breh,
No offense but you don't have a good handle on this info at all, along with what seems to be some reading comprehension issues... SMH
it's clear to me that you are out of you element.
1. We ARE NOT MELANSIANS, OR AUSTROLOIDS, OR NEGRITOS.
2. Learn about GENETIC DISTANCE, and why claiming we're connected to groups like Melansians is Foolish, especially with there being ZERO GENETIC EVIDENCE.
3. I've been on this journey of researching the GLOBAL history of the Black Man, Woman, and Child for DAMN Near 30 years. I didn't just watch a YouTube video a few weeks ago. I already know about "Precolumbian Blacks", You're not telling me anything new.
4. EVERY SINGLE Black American that is Genetically tested shows RECENT AFRICAN ANCESTRY.
5. Learn about GENETIC DISTANCE, and why Melansians can't be confused with Africans on a GENETIC LEVEL.
6. I Personally Took a DNA Test, and FOUND lost relatives (Here in America), that ALSO Had the EXACT Same African DNA Markers.
7. There is ZERO Requirement to "Genetically Test All Black Americans", before you can conclude that we are predominantly West Central African.
The FACT THAT ZERO of US have come back as Melanesian in a DNA Test, but MOSTLY West-Central African supports this.
8. ALL Anatomically Modern Humans have an origin in the African Continent.
9. Humans did NOT Have Independent Biological Origins,
if so WE WOULD NOT BE ABLE TO PROCREATE WITH DIFFERENT RACES. (If you can't comprehend this point, then there is ZERO REASON to talk to you about this)
My suggestion to you is to READ and Study more, and work on better Reading Comprehension, as your "Rebutal" to my previous statements are INADEQUATE!
