The North African genetic imput in Southern Italy is very insignificant according to the multiple studies, basically noise level:
At this respect, the distribution of Y-chromosome haplogroup E-M81 is widely associated in literature with recent gene flows from North-Africa [49]. Besides the low frequency (1.5%) of E-M81 lineages in general observed in our SSI dataset, the typical Maghrebin core haplotype 13-14-30-24-9-11-13 [8] has been found in only two out of the five E-M81 individuals. These results, along with the negligible contribution from North-African populations revealed by the admixture-like plot analysis, suggest only a marginal impact of trans-Mediterranean gene flows on the current SSI genetic pool. Together with the Berber E-M81, the occurrence of the Near-Eastern J1-M267 in Southern-European populations has been linked to population movements from the Near East through North-Africa, and particularly as a marker of the Islamic expansion over Southern-Europe (started approximately in the 8th century AD and lasted for more than 500 years). Fisher exact tests based on HGs frequencies have revealed the presence of haplogroup J1-M267 at significantly higher frequencies in both North-Africa and the Levant than in Sicily and Southern Italy (both P-values<0.001). However, the estimated age for Sicilian and Southern-Italian J1 haplotypes refers to the end of the Bronze Age (3261±1345 YBP), thus suggesting more ancient contributions from the East. Nevertheless, our time estimate does not necessarily coincide with the time of arrival of J1 in SSI; in fact a pre-existing differentiation could potentially backdate the time estimate here obtained.
The genetic origin of Y-chromosome haplogroups in Southern Italy and Sicily is 63% Balkan, 26% North Western European and 11% Levantine.

The Levant is an approximate historical geographical term referring to a large area in the Eastern Mediterranean region of Western Asia, so the correct definition here is "West Asian" admixture, not middleastern, which is a much more vague term.
I've already added many other genetic papers showing the same results, both for the uniparental and autosomal dna, but the user Venezia Friulano refuses to debate and just edits the page going against the conclusions of multiple DNA studies.
At over 16k words of readable prose, this article is too long to read comfortably. It would be beneficial to condense and/or migrate content to subarticles to make this one more readable. Nikkimaria ( talk) 16:37, 28 June 2023 (UTC)
- In my opinion the article is not too long. The topic is really very complex and multifaceted, and a detailed article is needed to have a complete treatment. -- LukeWiller ( talk) 17:21, 28 June 2023 (UTC).
- I appreciate that that might be your opinion, but that doesn't outweigh WP:TOOBIG. Complex and multifaceted topics are meant to be – and in many cases are – covered by summary style articles with more detailed child articles expanding on subtopics. Nikkimaria ( talk) 17:25, 28 June 2023 (UTC)
Espejo del Perú no es una fuente fiable, puesto que el sitio web es un blog. Acto seguido, la supuesta monografía que hace de referencia para varias de las ascendencias mencionadas en dicha página, dígase: [Abuhadba Rodrigues, Daniel (2007); Monografía: «Origen de los Apellidos en el Perú», Cusco, Perú, Fondo Editorial de la UNSAAC – Publicación disponible en la Biblioteca Universitaria de la UNSAAC (2007)], no existe en la mencionada biblioteca: véase. El autor tampoco existe fuera del sitio Espejo del Perú, cuando se le busca en buscadores como Google, Google Scholar, etc. no existe, cuando lo lógico es que haya más huellas de su aporte, considerando la importancia de sus supuestas contribuciones. Por ende, hace un buen tiempo que Espejo del Perú no es una fuente fiable para Wikipedia en español, y por ende, para toda Wikipedia, incluyendo su versión en inglés. Saludos.
