Pleistocene North African genomes link Near Eastern and sub-Saharan African human populations 2018
Marieke van de Loosdrecht1
Mitochondrial consensus sequences of the Taforalt indi-viduals belong to the U6a (n = 6) and M1b (n = 1) haplogroups (15), which are mostly confined to present-day populations in North and East Africa (7). U6 and M1 have been proposed as markers for autochthonous Maghreb ancestry, which might have been originally introduced into this region by a back-to-Africa migration from West Asia (6, 7). The occurrence of both haplogroups in the Taforalt individuals proves their pre-Holocene presence in the Maghreb. We analyzed the seven ancient Taforalt in combination with four Upper Paleolithic European mtDNA genomes (22, 23) and present-day individ-uals belonging to U6 and M1 (7) in BEAST v1.8.1 (24). Using a human mtDNA mutation rate inferred from tip calibration of ancient mtDNA genomes (23), we obtained divergence es-timates for U6 at 37,000 yBP (40,000-34,000 yBP for 95% highest posterior density, HPD) and M1 at 24,000 yBP (95% HPD, 29,000-20,000 yBP) (table S15). Our estimates are con-siderably younger than those of a study using present-day data only (45,000 ± 7000 yBP for U6 and 37,000 ± 7000 yBP for M1) (7), though similar to those of (25). Moreover, we ob-serve an asynchronous increase in the effective population size for U6 and M1 (fig. S24). This suggests that the demo-graphic histories of these North and East African haplog-roups do not coincide and might have been influenced by multiple expansions in the Late Pleistocene (25). Notably, the diversification of haplogroup U6a and M1 found for Taforalt is dated to ~24,000 yBP (fig. S23), which is close in time to

I doubt Haplogrep could assign a 'sequence' consisting of but a single solitary polymorphism at 100% certainty.
Years ago I explicitly exposed Kefi misrepresentating Taf 8; not including it SSA as far as a Maurusian founder yet counting it to beef the non-SSA percentage I'm not rehashing that all over again no matter how many times someome reposts one sided info from those old posts.
And really, if someone can't run Haplogrep or navigate Phylotree to confirm or falsify 100% assignment of 16223T to U4a2b then someone is baiting and shouldn't try posting about it on the Egyptology forum. It lowers the bar.
Even with a proper several polymorphism HVSI sequence HVSII and RFLP can reliably overturn a Hg assignment.

A Peer reviewed scientific article dated 2018 has reported Taforalt VII 16223T to be U4a2b. Not mentioning this "lowers the bar"

Gallego-Llorente passed peer review. Skoglund busted a cap in it. Sheeple.
I've reported after navigating Phylotree a few times already as you well know. You however have not.
If you can't contribute anything on 16223T the Hgs that have it (whew) U4a2b ___ ancient/current locations & dates ___ MRCA how to tell Hgs per sequences etc how can a single HVSI polymorphism be a Hg Then you're trolling and you know it. So please stop it now, thank you.
As a moderator you shouldn't bait and troll. As a moderator you should be silent when you don't have enough background to meaningfully comment.
Mining and verbatim posting what you don't understand and don't attempt to explain is OK but I require more, like analysis in your own words.
