Developmental constraints are restrictions on the development of a particular phenotypic trait. These are physical, mechanical or structural limitations as well as irreversible commitments at key developmental stages that will limit or bias the phenotypes that selection can work with. Accordingly, developmental constraints (and not stabilizing selection) explain why certain traits, such as the structure of the tetrapod limb, are highly conserved in different evolving lineages with different adaptive pressures (e.g. whale fins and frog legs).
