2014-06-05 Heterochrony. A heterochronic change is, in general, a change in the rate or timing of development of some cell lines in the body relative to others. A mutation that alters the rate at which a cell line develops relative to other cell lines is a heterochronic mutation. 2013-05-02 Is Heterochrony Still an Effective Paradigm for Contemporary Studies of Evo-devo? James Hanken 4.1 Introduction If there is one topic that can be most closely associated with the tremendous resurgence of interest in the relation between evolution and development that characterized biology in the late 1970s and 1980s, then surely it is heterochrony. Ontogeny; isometric and allometric growth; heterochrony; paedomorphosis and peramorphosis The demonstration of heterochrony is problematic in teaching palaeontology and evolution. 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.

Heterochrony is defined as evolutionary change in rates and timing of developmental processes; the dimension of time is therefore an essential part in studies of heterochrony.

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.
