The term heterochrony was first used by Ernst Haeckel (1875) to refer to temporal shifts in appearance of different organs during embryonic development within the same organism. In other words, it was the sequences of the Indeed, heterotopy and heterochrony do not refer to space and time as the abstract dimensions of physics but rather to their concrete cultural constructions: space as the built environment that constrains our urban experience and time as it appears In amphibian: Heterochrony. Neoteny, once a widely used label for the condition of sexually mature larvae, has been discontinued by biologists and replaced by the concept of heterochrony. Heterochrony refers to the change in the timing and rate of developmental events, and it is a widespread feature… Read More; termite castes and their roles The term heterochrony is now used to refer to a developmental process as well as to an evolutionary pattern. That is, it refers to a microevolutionary process of adaptation, operating in local populations under selection and to a macroevolutionary pattern based on undefined internal laws of form.

It is the retention in adults of traits previously seen only in the young. Such retention is important in evolutionary biology, domestication and evolutionary developmental biology.

heterochrony—systematic change in the rate or timing of a developmental stage or event that occurs over successive generations (Gould, 1977)—as a mechanism that not only integrates developmental and evolutionary timescales into a unifying framework, but that also reveals bi-directional influences between the two processes. Germination heterochrony refers to germination of seeds dispersed in a single growing season, which is different from delayed germination. Abstract. 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.

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. Foucault thought of archives, libraries, Heterochrony refers to an alteration in time, or a change in order, of one or more events.

Heterochrony can be divided into intrasp Heterochrony (from the Greek hetero meaning "other" and chronos meaning "time") describes a change in the timing of ontogenetic events between two taxa. These can be the result of relatively small genetic changes that may not even be alterations in DNA sequence, but in the timing of particular genes being expressed during development. Heterochrony, broadly defined, refers to evolutionary change in the rate or timing of development.
