Heterochrony Notes:
In evolutionary developmental biology, heterochrony is a developmental change in the timing or rate of events, leading to changes in size and shape of organs and features over evolutionary time scales. Heterochrony can be divided into intraspecific heterochrony that explains variation within a species, and interspecific heterochrony that explains developmental variation phylogenetically, in the timing or rate of events of a descendent species with respect to an ancestral species.
