The paper sequenced the mitochondrial genome of Lacantunia enigmatica and used it to construct a global catfish phylogeny, supporting its African origin and Late Cretaceous divergence.

This study compares adaptive radiations in two pupfish populations, finding limited genetic parallelism and highlighting the role of de novo mutations in driving rapid diversification.

The paper examines how pre-existing genetic constraints in generalist populations may limit adaptive divergence in two Caribbean Cyprinodon pupfish radiations, finding congruence between intraspecific variance and interspecific divergence axes.
