Putative case studies are valuable but are not always convincing, because: 1) students need to observe and compare the ontogeny of ancestors and descendants, and clear illustrations are seldom available: and 2) theoretical models of what heterochrony would be predicted to produce are usually missing. 1996-12-01 • 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).

2008-05-25 · The coinciding heterochrony and integration in syndactylous digits also cannot be explained by simple processes of locomotor adaptation, particularly because these patterns are conservative across the considerable diversity of locomotor types in Diprotodontia. Rather, syndactyly may represent a constraint that the foot is adapted to.
