Thanks to innovations in sequencing technology that have produced a cornucopia of genomes, plus some tweaks to the computational methods by different labs, the combined list of identified HARs now includes nearly 3,000 genome segments.4 But the original trend still holds; nearly all HARs are outside genes, some quite far away from
any gene in the genome.

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.
