To avoid unnecessary arguing about things with you and misunderstanding, I'm pointing out these two papers that were dropped in Sept 2022. Btw, it seems to me that after plenty of tedious and irritating discussions with some members here, you've run out of patience.

Likewise, European hunter gatherers are genetically predicted to have dark skin pigmentation and dark brown hair 9,10,17,18,115–118, and indeed we see that the WHG, EHG and CHG components contributed to these phenotypes in present-day individuals whereas the Yamnaya and Anatolian farmer ancestry contributed to light brown/blonde hair pigmentation (Supplementary Note 2g). Interestingly, loci associated with overdispersed mood-related polygenic phenotypes recorded among the UK Biobank individuals (like increased anxiety, guilty feelings, and irritability) showed an overrepresentation of the Anatolian farmer ancestry component; and the WHG component showed a strikingly high contribution to traits related to diabetes. We also found that the ApoE4 effect allele (increased risk for Alzheimer's disease) is preferentially found on a WHG/EHG haplotypic background, suggesting it likely was brought to western Europe by early huntergatherers (Supplementary Note 2g). This is in line with the present-day European distribution of this allele, which is highest in north-eastern Europe, where the proportion of these ancestries are higher than in other regions of the continent 119.

According to the authors of the paper "HG admixture facilitated natural selection in Neolithic Europeans.", not only ANF and Steppe ancestry but even the dark-skinned WHGs had alleles associated with lightening of European skin color.
..We see significant evidence of correlation between trait scores and LAD in Skin Colour (p = 3e-4 161 ), consistent with 162 the adaptive admixture around SLC24A5. Indeed, this signal is solely driven by two 163 loci, with a HERC2 variant with a skew towards the Mesolithic (Z=1.7) also 164 contributing to a lighter level of skin pigmentation alongside SLC24A5. Without these 165 two loci, there is no significant evidence of polygenic selection (P = 0.58). We also 166 observe a weaker but significant correlation for hip size (Figure 3, Supplementary 167 Figure 7). 168 169 The Neolithic transition brought about drastic changes in demography, culture and 170 diet, as well exposure to novel pathogens and increased potential of zoonotic 171 disease. In admixed middle Neolithic individuals, we found excess Neolithic farmer 172 ancestry at the pigmentation locus SLC24A5 and excess Mesolithic hunter-gatherer 173 ancestry at the MHC immunity locus. Previous studies also found evidence of natural perpetuity.

The copyright holder for this 5 selection at SLC24A5 in European populations26,27 174 and showed that the allele was introduced into Europe in the Neolithic2,37,38 175 but our study now further demonstrates 176 that this resulted in a removal of hunter-gatherer ancestry across the wider locus. In 177 a similar but opposite process, the MHC locus has previously been demonstrated to have undergone selection in the ancestry of present-day Europe239 178 and specifically in Neolithic Europe18 179 . Here, we obtain further robust results for selection at the MHC 180 locus corrected for multiple testing, and demonstrate that this process specifically 181 increased hunter-gatherer ancestry at the locus. 182 183In contrast to SLC24A5, the second high-effect, 184 displays an excess of Mesolithic ancestry (+17.23%, |Z| = ~3.11). Together with the 185 third high-effect pigmentation variant at SLC45A2, which arrived in Europe via later 186 expansions from the steppe, selection on pigmentation in Europe thus targeted variants from each of the three major ancestral populations9 187 . This highlights the 188 prominent role of admixture in the evolution of skin pigmentation in Western Eurasia.....
