Two copies of this mutation were present in almost all of the samples, including the hunter-gatherers, whose ancestors inhabited Europe during the Upper Paleolithic, and the first farmers, whose ancestors inhabited the Middle East during the Upper Paleolithic.The presence of the mutation in both these groups implies that it must have spread throughout the Caucasoid race and risen in frequency to near fixation before the Mesolithic, during the Upper Paleolithic.If people had paid attention to the time estimates for the coalescences and the selective sweeps for the depigmentation mutations, and to the fact that Europeans, and especially Northern Europeans, are lighter-skinned than Middle Easterners, then they would have realized that the idea that pre-Neolithic Europeans were all dark-skinned didn’t make any sense.Many people have made the same kind of foolish generalization based on the same Loschbour and La Braña 1 samples regarding the distribution of Y haplogroups in prehistoric Europe.The results for the large sample below show that their conclusion was false, and that Loschbour and La Braña 1 were among a minority of hunter-gatherers who lacked the mutations.They show that the truth is just the opposite of what they had been so quick to conclude; that it was the hunter-gatherers who were on average lighter-skinned than the first farmers.They’ve concluded, since Loschbour belonged to Y haplogroup I and La Braña 1 belonged to Y haplogroup C1a2, that Y haplogroup R1b must have been absent in Mesolithic Western Europe.

He shows a photograph of an artificially-darkened Mongoloid-admixed Lapp as being representative of all the Mesolithic hunters.

The 2012 paper estimated that the selective sweep for the SLC45A2 mutation started 16,000–13,000 years ago, but, again, this may be an underestimate.

The earlier DNA results for the Loschbour hunter-gatherer, who lived 8,000 years ago in Luxembourg, and the La Braña 1 hunter-gatherer, who lived 7,900 years ago in Spain, showed that neither of them had the SLC24A5 or SLC45A2 mutations.

Of course, it wasn’t just rashness that led many to their erroneous conclusion.

Many of these people believed what they did because it’s what they wanted to believe.
