THE BIOLOGY OF SPECIATION

Speciation rates can change due to the time it takes for a species to expand geographically and for populations to evolve reproductive isolation. Different factors like geographical opportunities and organismal properties can influence how speciation happens. Speciation rates can increase even without changes in climate or physical barriers. Diversification rates are an emergent property influenced by various factors. This study suggests new ways to understand how species evolve and diversify over time.
