The extraordinary species richness of freshwater fishes has attracted much research on
mechanisms and modes of speciation. We here review research on speciation in freshwater …

Rapid adaptive radiation poses two distinct questions apart from speciation and adaptation:
What happens after one speciation event and how do some lineages continue speciating …

Evolutionary biologists have long predicted that evolutionary trade-offs among traits should
constrain morphological divergence and species diversification. However, this prediction …

The interplay between evolutionary rates and modularity influences the evolution of
organismal body plans by both promoting and constraining the magnitude and direction of …

We review the origins, prominent innovations, and major patterns of diversification in suction
feeding by vertebrates. Non-vertebrate chordates and larval lamprey suspension-feed by …

Organisms inhabiting a specific environment often have distinct morphology, but the factors
that affect this fit are unclear when multiple morphological traits affect performance in …

Background Adaptive radiations are characterized by extreme and/or iterative phenotypic
divergence; however, such variation does not accumulate evenly across an organism …

Teleost fishes vary in their reliance on median and paired fins (MPF) or undulation of the
body (BCF) to generate thrust during straight-line, steady swimming. Previous work indicates …

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 …

The influence of biomechanics on the tempo and mode of morphological evolution is
unresolved, yet is fundamental to organismal diversification. Across multiple four-bar linkage …
