- Systematics and the Origin of SpeciesErnst Mayr, 1942Defines species by reproductive isolation rather than morphology, and argues geographic isolation of populations is the ordinary route to a new one.
- Evolutionary Rate at the Molecular LevelMotoo Kimura, 1968Argues most substitutions observed at the molecular level are selectively neutral and fixed by genetic drift, not natural selection, because the rate is too high and too clock-like for selection to explain.
