Invasion of new adaptive zones retains telltale signs of directional selection at macroevolutionary scales in mammals

Fabio Andrade Machado, Anna Penna, Diogo Melo…·Alex Hubbe

The paper examines directional selection during adaptive zone transitions in mammals, finding elevated evolutionary rates in most cases compared to genetic drift.
