One r****d said that Iranians were as equidistant from "white people" (meaningless term) as Eastern Eurasians.

"White people" is a meaningless term and "European" and "Middle Eastern" aren't much better.

We will use this study: "Genomic insights into the origin of farming in the ancient Near East" by Lazaridis et al 2016.

"We computed squared allele frequency differentiation between all pairs of ancient West Eurasians<a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5003663/#R28">28</a> (Methods; Fig. 3; Extended Data Fig. 2b; Extended Data Fig. 4), and found that the populations at the four corners of the quadrangle had differentiation of FST=0.08-0.15, comparable to the value of 0.09-0.13 seen between present-day West Eurasians and East Asians (Han) (Supplementary Data Table 3). In contrast, by the Bronze Age, genetic differentiation between pairs of West Eurasian populations had reached its present-day low levels (Fig. 3): today, FST is ≤0.025 for 95% of the pairs of West Eurasian populations and ≤0.046 for all pairs (Fig. 3). These results point to a demographic process that established high differentiation across West Eurasia and then reduced this differentiation over time."

That was easy enough!

"
The pattern of diversity at ASIP 8818*G allele (the ancestral allele associated with darker pigmentation) indicates a role primarily in African/non-African divergence (sub-Saharan African frequency: 66%, all other populations: 14%) rather than between darkly and lightly pigmented populations. At OCA2 355, the derived allele (linked with lighter pigmentation) occurs at its highest frequencies across Europe and Asia but is also relatively common among Native American populations (18–34%) and is present at much lower frequencies (0–10%) among Bantu-speaking African groups. In contrast, the ancestral allele associated with dark pigmentation has a shared high frequency in sub-Saharan African and Island Melanesians. A notable exception is the relatively lightly pigmented San population of Southern Africa where the derived allele predominates (93%), although this may be simply due to small sample size (n = 14).

The distributions of the derived and ancestral alleles at TYR A192C, MATP C374G, and SLC24A5 A111G are consistent with the FST results suggesting strong European-specific divergence at these loci. The derived allele at TYR, 192*A (previously linked with lighter pigmentation [Shriver et al. 2003]), has a frequency of 38% among European populations but a frequency of only 14% among non-Europeans. The differences between Europeans and non-Europeans for the MATP 374*G and SLC24A5 111*A alleles (both derived alleles associated with lighter pigmentation) were even more striking (MATPEuropean = 87%; MATPnon-European = 17%; SLC24A5European = 100%; SLC24A5non-European = 46%). The frequency of the SLC24A5 111*A allele outside of Europe is largely accounted for by high frequencies in geographically proximate populations in northern Africa, the Middle East, and Pakistan (ranging from 62% to 100%)."

If you don't know what "proximate" means, you need a dictionary.
