Our new #preprint changes the way we look at an “extinction vortex” in which a small population loses fitness, causing it to become even smaller https://www.biorxiv.org/content/10.1101/2024.10.25.620329v1.

Our latest paper https://elifesciences.org/articles/87335
directly measures the #EffectivePopulationSize that matters to #NearlyNeutralTheory / #DriftBarrier theory, as the degree to which #CodonBias differs from expectations from GC content. Surprisingly, stronger #NaturalSelection -> higher #IntrinsicStructuralDisorder proteins

The neutralist-selectionist debate needs moderating, and this paper makes some good contributions, but ultimately disappoints. It defends #NeutralTheory as acknowledging #BackgroundSelection, 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 #GeneticDrift with lower #EffectivePopulationSize. https://onlinelibrary.wiley.com/doi/10.1111/brv.13010?af=R 1/n

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

Our latest #preprint https://www.biorxiv.org/content/10.1101/2022.01.11.475913v2 @jdmatheson calls for significant change to the theory of #BackgroundSelection, a phenomenon by which some genomic segments of some individuals don’t count toward an #EffectivePopulationSize because they contain too many deleterious mutations. 1/5
