Cichlid fishes are hypothesized to encompass several independent adaptive radiations that
display increased diversification rates and impressive ecological heterogeneity. Here, I …

Adaptive radiations are known for rapid morphological and species diversification in
response to ecological opportunity, but it remains unclear if distinct mechanisms drive this …

In recent years, likelihood-based approaches have been used with increasing frequency to
evaluate macroevolutionary hypotheses of phenotypic evolution under distinct evolutionary …

One of the most endangered vertebrates, the Devils Hole pupfish Cyprinodon diabolis,
survives in a nearly impossible environment: a narrow subterranean fissure in the hottest …

Whole genome sequences are beginning to revolutionize our understanding of phylogenetic
relationships. Yet, even whole genome sequences can fail to resolve the evolutionary …

Trade-offs are thought to bias evolution and are core features of many anatomical systems.
Therefore, trade-offs may have far-reaching macroevolutionary consequences, including …

Divergence along a benthic to limnetic habitat axis is ubiquitous in aquatic systems.
However, this type of habitat divergence has largely been examined in low diversity, high …

Cichlids encompass one of the most diverse groups of fishes in South and Central America,
and show extensive variation in life history, morphology, and colouration. While studies of …

Convergence is central to the study of evolution because it demonstrates the power of
natural selection to deterministically shape phenotypic diversity. However, the conditions …

Innovations can facilitate bursts of diversification by increasing access to novel resources
and the attainment of novel functional designs. Pharyngognathy, exhibited by highly diverse …
