This information is so new and so, there is not any one source but I can gather up some information and references. This kind of information is scattered and I feel that the scientific community is not going to make it easy right now, for all to understand. And, it seems like they all waited until they had the approval from the White House before they even publicated this information about the Y-DNA. It was all released, I think, in 2012 and only certain organizations seems to have had the right to initially report it. But, nevertheless, all of the major scientific organizations across the world have agreed on this study about the Y-DNA having ONE ORIGIN and that is AFRICA and the AFRICAN MAN.
So, I have taken their references and my time lines and put it altogether. So, I will share what I have, but hopefully, I will gain the confidence to just write my own findings and publish myself! One of the terms scientist use to have determined this Afrian origin is BOTTLE NECK. What this sort of means in that they have studied the Y-Dna of groups of men all across the world, and all men have 'a base MARK' on their Y-Sex Chromosome. Then they study the similarities of other groups and they notice a distinct MARK that is the same in certain cultures, ... based on this kind of study, they know for certain that all men have the BASAL-A [i.e. 'A' meaning 'Adam'] on their chromosome. Father-and-son, have a unique MARK on thier chromosome, and on and on. So they can even pull Y-DNA samples from Mummies and determine the direct connection between grandfather-father-son. They can see the distinction from father and two sons and on and on.
African men have that BASAL-A MARK but do not have the same marks that other men in other cultures have but all males have that BASAL-A mark!!!
There is so much more to what they admit, but it is not easy for me too, to break it all down because I have not had the benefit of being in a classroom setting. But, I can follow the research very well. As far as the 4000 BC, timeline, there is one major scientific mark that scientist don't want to admit, but cannot ever deny and it would be this MARK that connects the MODERN HUMANS to have this origin with the Afican man and divides the earlier HOMONIDS from the Modern mankind, aside from the crucial fact that to date, there is NO Y-DNA extracted from any early Hominid fossil to even study yet! The presence of the Male Hominids from earlier times becomes scientifically obvious though for many reasons. But as of yet, Stanford University and others report that they only use female hybrid Neanderthals or etc. to make conclusions on the presence of male Neanderthals and such like.
The reason why this thread is kind of 'on point' about this one MARK that definds all Modern Homonids coming from the AFrican Male has to do with ----------
*************************************** AFRICAN HAIR TYPE!!! LOL******************************************
There is NO presence of NAPPY HAIR on any fossil or on any ancient cave drawings!!! Scientist hypothesize that maybe, the CroMagnon man may have had a MARKING on their CHROMOSOME for wavy hair, but this is not proven at all. Therefore, it is this MARK on the Y-DNA BASAL-A Chromosome that is the main MARK that defines the Modern Humans [ie Homo Sapiens] of our planet that shows the origins of all mankind!!! This too, leads to the mysterious statement and different 'Out of AFrica' Theory about the two distinct classifications of females... I will look for some references.
I do not understand you completely but I do understand about having godlike abilities.
