The impact of social complexity on the efficacy of natural selection in termites
Published 2024-10-01“…First, by analyzing transcriptome data from 66 Blattodea species, we focus on the ratio of non-synonymous to synonymous mutations dN/dS as a marker of natural selection efficiency and effective population size. …”

Inactivation of the CMAH gene and deficiency of Neu5Gc play a role in human brain evolution
Published 2025-02-01“…An inactivation mutation in CMP-N-acetylneuraminic acid hydroxylase (CMAH) was the result of natural selection. The inactivation of CMAH protected our ancestors from some pathogens and reduced the level of N-glycolylneuraminic acid (Neu5Gc) in brain tissue. …”

The landscape of nucleotide diversity in Drosophila melanogaster is shaped by mutation rate variation
Published 2023-04-01“…Attempts to answer this question have sparked debate about the roles of neutral stochastic processes and natural selection in molecular evolution. However, the mechanisms of evolution do not act in isolation, and integrative models that simultaneously consider the influence of multiple factors on diversity are lacking; without them, confounding factors lurk in the estimates. …”

Individual differences in developmental trajectory leave a male polyphenic signature in bulb mite populations
Published 2023-12-01“…If, like in mammals and birds where early-life stress effects are extensively studied, we account for such pre-adult viability selection in coldblooded species, it would allow us to (i) better characterise natural selection on trait development like male polyphenisms, (ii) understand how it can affect the response to other selections in adulthood, and (iii) understand how such trait dynamics influence, and are influenced by, population dynamics. …”

Codon usage patterns and genomic variation analysis of chloroplast genomes provides new insights into the evolution of Aroideae
Published 2025-02-01“…The ENC-plot and PR2-plot revealed that the codon usage bias of Aroideae was influenced by multiple factors, with natural selection as the dominant factor. Thirteen to twenty optimal codons ending in A/T were identified in 61 Aroideae species. …”
