This is a post intended for fellow Arabs and other native inhabitants of the Arab world - the cradle of civilization.
Practically all Semitic and non-Semitic civilizations and cultures native to the Arab world, which are the oldest in the world, were all created by our ancestors.
In fact people from KSA and other Arabians have in fact the closest genetic kinship to the Natufians (world's oldest culture, first Neolithic culture in the world first builders of cities, first agriculturists in the world, first large-scale domestications of animals etc.).
All confirmed by modern-day DNA tests.

Basal Eurasian
Basal Eurasian is a proposed lineage of
anatomically modern humans with reduced, or zero,
Neanderthal admixture (ancestry) compared to other ancient non-Africans. They diverged from other Eurasians after the
Out-of-African migration and represent a sister lineage to other Eurasians. Basal Eurasians originate from the Southern
Middle East, specifically from
Prehistoric Arabia, or
North Africa, and are said to have contributed ancestry to various
West Eurasian,
South Asian, and
Central Asian as well as African groups.<a href="

https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-:0-2"><span>[</span>2<span>]</span></a>
This Basal Eurasian component is also proposed to explain the lower archaic admixture among modern West Eurasians compared with East Eurasians, although alternative explanations without need of such Basal admixture exist as well.<a href="

https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-:0-2"><span>[</span>2<span>]</span></a> Basal Eurasian ancestry had likely admixed into West Eurasian groups present in West Asia as early as 26,000 years ago, prior to the
Last Glacial Maximum, with this ancestry being subsequently spread by later migrations, such as those of the
Anatolian Neolithic Farmers into Europe during the Holocene.<a href="

Description
A 2014 study by Lazaridis et al. demonstrated that modern Europeans can be modelled as an admixture of three ancestral populations;
Ancient North Eurasians (ANE),
Western Hunter-Gatherers (WHG), and
Early European Farmers (EEF).<a href="
https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-FOOTNOTELazaridis_et_al.2014-5"><span>[</span>5<span>]</span></a> This same study showed that EEFs harbour ancestry from a hypothetical non-African 'ghost' population which the authors name 'Basal Eurasians'. This group, who have not yet been sampled from ancient remains, are thought to have diverged from all non-African populations c. 60,000 to 100,000 years ago, before non-Africans admixed with Neanderthals (c. 50,000 to 60,000 years ago) and diversified from each other.<a href="

A 2016 study by Lazaridis et al. found that populations with higher levels of Basal Eurasian ancestry have lower levels of Neanderthal ancestry, which suggests that Basal Eurasians had lower levels of Neanderthal ancestry compared with other non-Africans. A 2021 study by Ferreira et al. suggested that Basal Eurasians diverged from other Eurasians between 50,000 and 60,000 years ago, and lived somewhere in the Arabian peninsula, specifically the Persian Gulf region, shortly before proper Eurasians admixed with a Neanderthal population, in a region stretching from the Levant to northern Iran.<a href="

Vallini et al. 2024 argues that the Basal Eurasian lineage diverged from other Eurasians soon after the Out-of-Africa migration, and subsequently became isolated, until it started to mix with other populations in the Middle East since around 25,000 years ago. These different Middle Eastern populations would later spread Basal Eurasian ancestry via the Neolithic Revolution to all of Western Eurasia.<a href="
https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-:0-2"><span>[</span>2<span>]</span></a>
In modern populations, Neanderthal ancestry is around 10% to 20% lower in West Eurasians than East Eurasians, with intermediate levels found in South and Central Asian populations. Although a scenario involving multiple admixture events between modern humans and Neanderthals is an alternative possibility, the most likely explanation for this is that Neanderthal ancestry in West Eurasians and South and Central Asians was diluted by admixture with Basal Eurasian groups.<a href="

Possible geographic origin
The earliest evidence of Basal Eurasian ancestry is found in individuals from
Dzudzuana Cave [
Wikidata] in Georgia dating to 26,000 years ago which have around 30% Basal Eurasian ancestry, with the rest being West Eurasian.<a href="
https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-:2-4"><span>[</span>4<span>]</span></a>
Basal Eurasians may have originated in a region stretching from North Africa to the Middle East, before admixing with West-Eurasian populations.<a href="

Ferreira et al. in 2021 argued for a point of origin for Basal Eurasians into the Middle East, specifically in the Persian Gulf region on the Arab peninsula. As Basal Eurasians had low levels of Neanderthal ancestry, genetic and archaeological evidence for interactions between modern humans and Neanderthals may allow certain areas, such as the Levant, to be ruled out as possible sources for Basal Eurasians. In other areas, such as southern Southwest Asia, there is currently no evidence for an overlap between modern human and Neanderthal populations.<a href="

Vallini et al. 2024 suggests a homeland for Basal Eurasians in the Arabian Peninsula, with a 'Common Eurasian Hub' in the
Iranian Plateau, where they diverged into '
Ancient West Eurasians' and '
Ancient East Eurasians'.<a href="

An estimation for
Holocene-era Near Easterners (e.g., Mesolithic
Caucasus hunter-gatherers,
Mesolithic and Neolithic
Iranians, and
Natufians) suggests that they formed from a combination of Basal Eurasian ancestry, and
Western Hunter-Gatherer-related (WHG) and or
Ancient North Eurasians-related (ANE) ancestries respectively.<a href="
https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-FOOTNOTEvan_de_Loosdrecht_et_al.2018-11"><span>[</span>11<span>]</span></a>
The Mesolithic and Neolithic Iranian lineage is inferred to derived between 38–48% ancestry from Basal Eurasians respectively, with the remainder ancestry being made up by Ancient North Eurasian or
Eastern Hunter-Gatherer (EHG) like ancestry, while Natufians derived a mean average of 50% Basal and 50% 'unknown hunter-gatherer' ancestry being closer to Western Hunter-Gatherers (WHG).<a href="

https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-:1-15"><span>[</span>15<span>]</span></a> Alternatively, Mesolithic and Neolithic Iranians derive most of their ancestry from a deep West Eurasian source (WEC2; c. 72%) with c. 18% Basal Eurasian and c. 10%
Ancient East Eurasian admixture.<a href="

It has been found that the "models of genetic history of West Asian human populations who are modeled as a mixture of 'basal Eurasians' and West European hunter–gatherers" is in agreement with the genomic data on 'East Mediterranean
Dogs', who "are modeled as a mixture of a basal branch (splitting deeper than the divergence of the Asian and European dogs) and West European dogs".<a href="
https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-17"><span>[</span>17<span>]</span></a>
The Ancient North African
Iberomaurusian (
Taforalt) individuals were found to have harbored ~65% West Eurasian-like ancestry and considered likely direct descendants of such "Basal Eurasian" population. However they were shown to be genetically closer to Holocene-era Iranians and Levantine populations, which already harbored increased archaic (Neanderthal) admixture.<a href="
https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-FOOTNOTEvan_de_Loosdrecht_et_al.2018-11"><span>[</span>11<span>]</span></a>
Early European Farmers (EEFs), who had some
Western European Hunter-Gatherer-related ancestry and originated in the Near East, also derive approximately 30% (to up to 44%) of their ancestry from this hypothetical Basal Eurasian lineage.<a href="
https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-FOOTNOTELazaridis_et_al.2014-5"><span>[</span>5<span>]</span></a><a href="
https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-18"><span>[</span>18<span>]</span></a> An
Upper Paleolithicspecimen from Kotias Klde cave in the
Caucasus (Caucasus_25,000BP) had around 24% Basal Eurasian and 76% Upper Paleolithic European ancestry.<a href="
https://en.wikipedia.org/wiki/Basal_Eurasian#cite_note-:1-15"><span>[</span>15<span>]</span></a>
Among modern populations, Basal-like ancestry peaks among
Arabs (such as
Qataris) at c. 45%, and among
Iranian populations at c. 35%, and is also found in significant amounts among modern Northern Africans, in accordance with the high affinity towards the 'Arabian branch' of Eurasian diversity, which expanded into Northern and Northeastern Africa between 30 and 15 thousand years ago. Modern populations of the
Levant derive between 35-38% ancestry from Basal Eurasians, modern Anatolians and populations from the
Caucasus derive between 25-30% ancestry from Basal Eurasians, and modern
Europeans derive around or less than 20% ancestry from Basal Eurasians.<a href="

Modern
Bedouins and
Yemenis are considered to represent direct descendants of the Basal Eurasians, carrying the highest amount of indigenous 'Arabian ancestry', and being basal to all modern Eurasian populations without displaying higher 'African-associated' admixture, and thus "are among the best genetic representatives of the autochthonous population on the
Arabian Peninsula".<a href="

Great combination of admixture as well from our part.
In other words - Basal Eurasian ancestry is a
major ancestral component in Levantine, Arabian, Anatolian, Iranian, and other Neolithic Near Eastern populations.
Levantine ancient Neolithic farmers (which Saudi Arabians have the closest genetic affinity to of all people) are the earliest Neolithic peoples and influenced the Anatolian Neolithic farmers greatly genetically.
So once again, like throughout most of history, it was Arabians/Arabs that influenced everyone else genetically in the region and from there on the entire Eurasian continent which is also confirmed by haplogroups, human migrations, the birth of civilization, advanced cultures and now modern-day DNA.
Pretty amazing, if you ask me.
Even fairly recent times (3000 years ago), Semitic speaking Arabians influenced Horn of Africa greatly genetically to the extend that almost 50% of their DNA derives from Arabians. We are talking about the cradle of African culture (Horn of Africa), one of the most populous regions of Africa and also the apparent birthplace of humans as a whole.
