Il faudra attendre d'autres études pour trancher. Attention, pour l'instant, on ne traite que d'un seul individu ... C'est loin de faire un population. Même en 70 siècles
Une autre étude publiée par Lazaridis en décembre 2013 avait déjà montré ceci:
* un mésolithique de Loschbour au Luxembourg avait la peau sombre, les cheveux noirs et les yeux bleus
* un néolithique du rubané de Stuttgart avait la peau claire, les cheveux noirs et les yeux marrons.

For hair color, the integrated results of the genotype-based pigmentation models indicate that there is at least a 99% probability that both the Stuttgart and Loschbour individuals had dark (brown or black) hair.
The results of the 8-plex skin pigmentation model were inconclusive for both the Loschbour and Stuttgart individuals. However, the Loschbour and Stuttgart genotypes at rs1426654 in SLC24A5 indicate that the Stuttgart individual may have had lighter skin than the Loschbour hunter and gatherer.
For eye color, the single most significant determinant is the rs12913832 SNP in the HERC2 gene. The genotype at this site excludes the possibility that the Stuttgart farmer had blue eyes. Positive iris color determinations are less secure. The Loschbour forager is homozygous for the derived allele at rs12913832, indicating that this individual is likely to have had blue (52% proba bility) or intermediate iris color (27% probability). It has been suggested that this mutation arose within the last 6,000 to 10,000 years, and thus the Loschbour individual would have been a relatively early carrier.
Il semble donc que le mésolithique du Luxembourg ressemblait comme deux gouttes d'eau au mésolithique espagnol.
