The concept of heterochrony is a persistent component of discussions about the way that evolution and development interact. Since the late 1970s heterochrony has been defined largely as developmental changes in the relationship of size and shape. This approach to heterochrony, here termed growth heterochrony, is limited in the way it can


Heterochrony refers to any change in the timing or development rate of an organism or individual concerning its ancestor. It is an important macroevolutionary change in the development of embryos. The pattern of change in the development of the embryo is studied in heterochrony.

Reference Alberch, Gould, Oster and Wake 1979 or the rate of a developmental process. The term heterochrony refers to changes in the relative time of developmental processes between ancestors and descendents, but in practice heterochrony is applied in a comparative sense to changes among taxa that are related at some level. The concept of heterochrony has accompanied attempts to link DeBeer’s (1958) classic treatment of heterochrony remains the basis for modern systems of nomenclature (Gould, 1977; Alberch et al., 1979; McNamara, 1986). The central component of what we will refer to as deBeerian heterochrony is the explicit comparison of somatic growth or morphogenesis with Heterochronia does not refer to time as an abstract dimension of physics but rather to time as a social and political construction.

Heterochrony refers to a change in the relative timing or rate of development of morphological features that occur in the ancestor and the descendant. This is an evolutionary concept that invokes shifts in developmental timing as a major force in the evolution of new forms. Different from the single heterochronic process that resulted in morphological change, complex heterochrony refers to the combination of heterochronic processes affecting the same parameter, that is, shape or trait (Neige et al.

In evolutionary developmental biology, heterochrony is any genetically controlled difference in the timing or duration of a developmental process in an organism

Heterochrony refers to those permutations in timing of differentiation events, and those changes in rates of growth and development through which morphological changes and novelties originate during phyletic evolution. Neoteny, also called juvenilization, is the delaying or slowing of the physiological development of an organism, typically an animal. Neoteny is found in modern humans. In progenesis, sexual development is accelerated.
