Blue eyes and dark skin

Spanish hunter-gatherer had blue eyes and dark skin

Excerpt: The arrival of the Neolithic, with a carbohydrate-based diet and new pathogens transmitted by domesticated animals, entailed metabolic and immunological challenges that were reflected in genetic adaptations of post-Mesolithic populations. Among these is the ability to digest lactose, which La Braña individual could not do.
My comment: Journal article abstract excerpt: “The adoption of farming, stock breeding and sedentary societies during the Neolithic may have resulted in adaptive changes in genes associated with immunity and diet.
See: Nutrient-dependent/pheromone-controlled adaptive evolution: a model
In that recent review, I detailed how nutrient-dependent epigenetically-effected alternative splicings in pre-mRNA led to amino acid substitutions and chromosomal rearrangements manifested in the species-specific cell types of different individuals in different species with specific morphological and behavioral phenotypes.
As has since exemplified in published works on birds and bees, mutation-driven evolution is no longer considered to be ecologically valid or biologically plausible, since ecological adaptations are clearly nutrient-dependent and pheromone-controlled in species from microbes to man.
For attempts to discuss these biological facts on the International Society for Human Ethology’s yahoo group, see my series of comments on
de novo creation of olfactory receptor genes and downstream effects and affects 
de novo gene creation sans mutations (as previously reported)
Removing experimental evidence of amino acid/noncoding polymorphism  Here’s another way to skew the reporting of results in favor of mutation-driven evolution: Remove any results that indicate amino acid substitutions may be involved in selection for morphological and behavioral traits of of nutrient-dependent phermone-controlled reproduction.
de novo gene creation sans mutations (as previously reported)  the author of Mutation-Driven Evolution decided a few years ago to: “…not consider geographical and ecological factors because of space limitation.”
