• Today’sdefinition of heterochrony ‘the mechanism that produces a parallel between ontogeny and phylogeny’. • Heterochrony involves a shift in the timing of developmental processes so an event occurs earlier, later, or at a different rate in a taxon compared to its ancestor. 8 (Leonard & James, 1993) Embryonic development and stripe patterns of the zebras Equus burchelli (top) and grevyi (bottom).
