The ontogeny programs are highly conserved across all vertebrates, although there are significant temporal variations in interspecies developmental processes. Changing the timing and rate of developmental processes could affect subsequent organogenesis profoundly and may also have been critical factors in evolutionary diversity. However, despite their potential importance, the cellular and molecular mechanisms that control interspecies differences in developmental timescale remain unclear. This review highlights recent advances in the experimental models to compare interspecies differences in neurodevelopmental processes, neurogenesis, and neuronal maturation and discusses the possible mechanisms that could generate species-specific timescales.
