This study examines how extinction patterns varied over time in early vertebrates, showing shifts from clustered to overdispersed extinction during key evolutionary periods.

The paper examines phenotypic evolution in three living fossil lineages, finding varied evolutionary patterns across and within lineages, suggesting idiosyncratic processes rather than uniform change.

This study examines the role of salinity and other factors in shaping body size evolution rates across fish species at multiple scales, finding limited salinity influence and stronger effects from species richness and lake environments.
