Does phenotypic plasticity promote (Baldwin effect) or hinder (Mayr) genetic adaptation? Lambert et al. mathematically show that when adaptive plasticity increases, the Baldwin effect increases, peaks then decreases as plasticity begins to mask selection.

The Baldwin Effect Reloaded: Intermediate Levels of Phenotypic Plasticity Favor Evolutionary Rescue | The American Naturalist

Abstract Since the late 1890s up until today, how phenotypic plasticity interacts with genetic adaptation has been a debated issue. Proponents of a positive causal role of phenotypic plasticity—James ...

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

How many chromosomes can an animal have?

In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact.
