Data from: High evolutionary constraints limited adaptive responses to past climate changes in toad skulls

Monique Nouailhetas Simon, Fabio Andrade Machado & Gabriel Marroig
Interactions among traits that build a complex structure may be represented as genetic covariation and correlation. Genetic correlations may act as constraints, deflecting the evolutionary response from the direction of natural selection. We investigated the relative importance of drift, selection, and constraints in driving skull divergence in a group of related toad species. The distributional range of these species encompasses very distinct habitats with important climatic differences and the species are primarily distinguished by differences...
