Till Selection Do Us Part? Testing Sexual Selection’s Role in Speciation

Till Selection Do Us Part? Testing Sexual Selection’s Role in Speciation

Posted on by Pooja Radhakrishnan, edited by Genrietta Yagudayeva

Read about “Evolutionary lability of sexual selection and its implications for speciation and macroevolution” by Matheus Januario, Renato C. Macedo-Rego, and Daniel L. Rabosky (April 2025)

Januario et al. found no correlation between sexual selection intensity & speciation rates or proxy traits (SSD and dichromatism). Because sexual selection intensity has high intraspecific variation and low phylogenetic signal, its macroevolutionary impacts are weak
