Why is the true Negro theory still being used in 2023 in population genetic studies?

[QUOTE]Originally posted by Elijah The Tishbite: [QB] [QUOTE]Originally posted by the lioness,: [qb] [QUOTE]Originally posted by Elijah The Tishbite: That study uses Ju hoan North as the represenative African population, they are from South Africa [/qb][/QUOTE]It doesn't say it's supposed to representative of the whole of Africa Some of the lower coverage civilian genomes exhibit a small proportion of the component maximized in the southern African Ju|’hoan which is also found as a minor component in the Punic individuals from Sardinia and Ibiza as well as Eastern Mediterranean and North African individuals The similarity to Punic individuals is also supported by the presence of a small proportion of the component maximized in Ju|’hoan in some individuals. This, as well as the slight genetic heterogeneity they show, might alternatively be an artefact of the low coverage of the samples. One line of evidence for some local genetic continuity is the almost exclusive presence of Y-chromosomal haplogroup G-Z1903 and its derivates among the males (Dataset S6), a lineage already found among Sicilian inhabitants in the Middle Bronze Age (MBA) and LBA (12) and otherwise unreported from any pre- or early historic contexts, including Iberia. One male belongs to haplogroup R-FT40455, which is a specific subtype of haplogroup R-DF27, which could reflect an Iberian source of ancestry, as it is much more common in Iberia from the BA onward than in any other region (19, 56). R-DF27 has also been observed in individuals of the EBA in Sicily (12) and thus could have that persisted to the time of the Sicani culture. Their mitochondrial DNA (mtDNA) haplogroups suggest east Eurasian genetic roots: A6a, found so far only in modern-day China (70, 71), and N1a1a1a, restricted to Russia, Kazakhstan, and Mongolia (72). https://www.pnas.org/doi/10.1073/pnas.2205272119#supplementary-materials [/QB][/QUOTE]If they wasn't using them as the representative sample for all of Africa why is that sample in there? They have zero to do with the target population of the study. [/QB][/QUOTE]
