These can produce big results, and I think are likely crucial in morphological evolution in addition to structural changes (even if it turns out that the latter is more important), especially when change is occurring rapidly or among reasonably closely related forms that share a body plan that is modified in various ways.

This has some interesting implications not only with respect to long-term morphological stasis, but also with respect to long-term stasis of an ecology as represented by the Burgess Shale type fauna.
