[QUOTE]Originally posted by xyyman: [QB] When I post I serve two purposes. To educate newbies and also to answer your question at the same time opening your mind. That said - Agreed : “The mutations don't occur because they NEED to they are SELECTED FOR because they are needed” . That is why I believe with trepidation that whit eskin alleles is ancestral but at the same time we became humans because we were black. Confused? Quote : “supp table you posted from Malick showing the high level of snp diversity in Africans and basically the opposite for Europeans” . yes, this is why researcher Shriver and Company had no other choice to concluded light skin originated in Africa and the clue came from the West Africans Cape Verdians. But they stopped at the pigmentation genes. It is only when I took a second look at the paper on Cape Verdian paper I realize they are North Africans, not West Africans, and it is quite possible R1b-M269 existed in this West African Island BEFORE European colonization. More work is needed there. Quote : “remember how falloff in gene diversity was calculated via IBD “ - Clearly you have a statistical background. But Statistics can be manipulated. I have a science/engineering background but I know enough about statistics to do damage. Lol! I look at things in the absolute. Sides the genetic is really High School Biology. It is not that complicated. Quote: “Even if you were right about Africans entering Europe and morphologically changing” [b]“I”[/b] am not right. This is freely available information published by researchers. The transition is seen across the ***globe***. “Negroes” to the south and lighter skin to the North. I did not make this up. This is what it is. I remember I posted a paper several years ago and I lost it. It is buried somewhere on one of my computers. The researcher, from the 1900’s made the world population is really divided between North and South. I posted the paper on ESR and here but it will take me some time to find it. As for the diversity of Europeans compared to Asians or North Africans? Asians are from the FIRST OOA and very old. There is no TWO populations to Asians as with Europeans. Paper cited. Europeans apparently started as a small hunter gatherer population ie bottle neck. Which later admixed with the incoming Neolithics who are also a subset of the greater Africans. Result…….less diversity. This is not rocket science. [QUOTE]Originally posted by Elmaestro: [qb] Xyyman can't see that his questions were already answered, furthermore he himself already answered these questions. [i]what are the facts?[/i] [QUOTE]- modern Europeans have the lowest score for genetic diversity. - modern Europeans are generally homogeneous when looking at area per gene ratio. - R1b now Dominates Europe. - Modern Europeans score highest for mutational load despite there being no evidence for ineffectiveness of removing deleterious mutations[/QUOTE]Neanderthal were mostly black. Neolithic Europeans were tropically adapted. [i]what can be inferred[/i] Europeans, went through multiple admixture events and one major bottleneck or evolutionary event recently. The event which resulted in widespread homogeneity have yet to be explained. There are PLENTY of polymorphisms within coding regions of pigment related genes. The mutations don't [b]occur because they NEED to[/b] they are [b]SELECTED FOR because they are needed[/b]. In other words mutations aren't adaptions but if we so happen to have a mutation that increases survivability, chances are it will be passed don't more efficiently. You remember that supp table you posted from malick showing the high level of snp diversity in Africans and basically the opposite for Europeans ...? remember how falloff in gene diversity was calculated via IBD? Do you not see how all of this coincides with what I've been posting, geneflow, bottlenecks, variations? Even if you were right about Africans entering Europe and morpholgically changing, how do you explain the disparity between African diversity and Europe, or even SSAn diversity and North Africa? You're cutting corners. [/qb][/QUOTE] [/QB][/QUOTE]
