Heterokroni - Heterochrony - qaz.wiki

Heterochrony can be defined as change to the timing or rate of development relative to the ancestor. Because organisms generally change in shape as well as increase in size during their development, any variation to the duration of growth or to the rate of growth of different parts of the organism can cause morphological changes in the descendant form.

(1979), in which heterochrony is defined as “change in timing or rate of developmental events, relative to the same events in the ancestor,” became the cornerstone for studies, particularly paleontological, in heterochrony through much of the remainder of the twentieth century, and has been the basis for our own studies in the subject (McKinney 1988; McKinney and … Heterochrony (= different time) is any change in the timing of development in an animal or plant.
