Reacción a "Reactions: modern humans record fewer chromosomal errors during brain development than Neanderthals and apes"

This type of functional work exploring the effects on living individuals of the hundred or so differences in genes previously found between Neanderthals and modern humans shows, on the one hand, the experimental complexity involved in understanding these differences. On the other hand, they reflect the difficulties of extrapolating them in a comprehensible way to the evolution of both lineages.
