Prezygotic (sexual) isolation evolves faster than postzygotic isolation. Re-drawing of data from Coyne and Orr (1997) contrasting premating (behavior) and postzygotic (sterility/inviability) rates of reproductive isolation across 86 Drosophila species pairs over a range of divergence times. Nei’s Genetic Distance (D) is used as a proxy for divergence. Only species pairs with both pre- and postzygotic isolation estimates were used
