The neutralist-selectionist debate needs moderating, and this paper makes some good contributions, but ultimately disappoints. It defends as acknowledging , but does not qualify that this is only a limited form of background selection - one with strong deleterious effects and Ud<1, such that background selection can be captured by a 1-locus model of random with lower . onlinelibrary.wiley.com/doi/10 1/n

Our preprint describes how affects usage. biorxiv.org/content/10.1101/20. Within highly exchangeable pairs of amino acids, high Ne species are able to prefer over , and over . This matches preferences, as expected from theories of marginal protein stability at mutation-selection-drift balance. 1/6

Background selection at unlinked sites might not matter if it can be well captured by describing in a 1-locus model. So we added a figure to demonstrate that this isn't the case. 6/5

Our latest biorxiv.org/content/10.1101/20 @jdmatheson calls for significant change to the theory of , a phenomenon by which some genomic segments of some individuals don’t count toward an because they contain too many deleterious mutations. 1/5
