Stochastic Character Mapping of State-Dependent Diversification Reveals the Tempo of Evolutionary Decline in Self-Compatible Onagraceae Lineages

Newsemia
Abstract A major goal of evolutionary biology is to identify key evolutionary transitions that correspond with shifts in speciation and extinction rates. Stochastic character mapping...

Cartilaginous Fishes Provide Insights into the Origin, Diversification, and Sexually Dimorphic Expression of Vertebrate Estrogen Receptor Genes

Newsemia
Abstract Vertebrate estrogen receptors (ERs) perform numerous cell signaling and transcriptional regulatory functions. ERɑ (Esr1) and ERβ (Esr2) likely evolved from an ancestral receptor that...
