[QUOTE]Originally posted by Swenet: [QB] [QUOTE]Originally posted by The Explorer: There is no such thing as "proto-Afro-Asiatic mtDNA".[/QUOTE]You're conjuring up distractions and you're not addressing what I'm telling you. The reason is obvious; you can't. I correctly anticipated that you'd use M1 and/or U6 as evidence of large effective population sizes for proto-Berber speakers and I stopped you dead in your tracks by making you face your earlier ridiculous commitment to the idea that M1 and U6 were spread by proto-Afrasan speakers around the same time as the Natufians. You presented U6 and M1 as clades that were spread by proto-Afrasan speakers, totally ignoring the fact that your silly theory is at odds with the evidence, from the glaring lack of ''Ogolian'' Maghrebi archaeological sites interpretable as associated with proto-Afrasan peoples, to the inconvenient fact that the molecular characteristics of these clades point to events that happened way before this, to the inconvenient fact that certain old Maghrebi-specific M1 and U6 subclades (M1b and U6a1) in other branches of Afasan cannot be attributed to common inheritance from proto-Afrasans, but represent admixture. [QUOTE]Originally posted by The Explorer: What you need to be focusing on at the moment, is why you haven't accounted for the Maghrebi paternal gene pool that is lopsidedly "African"[/QUOTE]I already did, and not only did you not address my explanation, being the coward that you are, you also refrained from defending your objections (i.e., the patently stupid assertion that alleged M78 diversity rules out drift or that there were large effective population sizes), after I obliterated them. Repeat: [i] While you're at it, if drift isn't at work here, explain the discrepancy between the extreme rarity of ancestral clades in between E-M81 and E-M35, even though the former only emerged ~5.6kya from the said predecessors.[/i] --Swenet [i] Then demonstrate that the paternal East African component brought there by Neolithic proto-Berber speakers (e.g., manifested as E-M81 in Y Chromosomal analysis) re-emerges as East African affiliated ancestry when other ancestry informative markers are consulted[/i] --Swenet [QUOTE]Originally posted by The Explorer: To the chump above (swenet), uniparental markers are not univariate entities. They span multiple loci, some more variable than others, as any other segment of the human genome. This is not cranio-morphometric analysis where individual features are examined for their variability.[/QUOTE]Lol, this loon thinks that the loci that are involved with haplogroup assignment are the same thing as variables. They're not dumbass, as they're not used as standalone variables that, together, measure more than one thing. In other words, they don't lead to more than one factual haplogroup assignment. The most important reason why there is more than one locus is to account for homoplasy. As I suspected, you're hopelessly deprived of any sense that could clue you in on the fact that you have no idea, whatsoever, what you talking about. Evidence for this is your horribly misplaced suggestion that the term 'multi-variate' has no applicability outside the field of morphometrics. [QUOTE]Originally posted by The Explorer: and their language that is entirely unique to Africa,[/QUOTE]What the hell does this have to do with whether their M81 levels are truly representative for how much East African ancestry Maghrebi populations have in their overall genome, that can be attributed to pastoral proto-Berber speakers? Answer: nothing, but you just thought you'd randomly insert that trivial observation, because you're random like that. [/QB][/QUOTE]
