Compared with living people, Neandertals and ancient Siberians known as Denisovans had slightly different patterns of DNA methylation — a chemical modification of DNA that doesn't change the information in genes but helps control gene activity.

Given that most amino acid changes are slightly deleterious [12] and assuming that most genes in the genome are relatively conserved, one would expect that regions of the genome with a low recombination rate, when compared to those with a high rate, would show i) a higher ratio of non-synonymous (amino acid replacing) to synonymous (silent) substitutions (ω) and ii) a higher degree of protein divergence (dA) due, in both cases, to the reduced effectiveness of selection against slightly deleterious mutations.
