Intraspecific heterochrony means changes in the rate or timing of development within a species. For example, some individuals of the salamander species Ambystoma talpoideum delay the metamorphosis of the skull. Reilly et al argue we can define these variant individuals as paedotypic (with truncated development relative to Medical definition of heterochrony: deviation from the typical embryological sequence of formation of organs and parts as a factor in evolution.

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. Over the past two decades, evolutionary biologists have used several methodological frameworks to analyse heterochrony, 2010-08-24 Heterochrony has been invoked to explain differences in the morphology of modern humans as compared to other great apes.

All Free. The model proposed by Alberch et al. (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. It is a key concept in developmental biology and evolution, introduced by Ernst Haeckel in 1875. Heterochrony: It’s (all) about time! Matthew Schlesinger Department of Psychology Brain and Cognitive Sciences Southern Illinois University Carbondale, IL 62901 matthews@siu.edu Abstract Heterochrony—variation in the rate or timing of developmental processes or events over evolutionary time—plays an important role in the study of Definition of Heterochrony in the Definitions.net dictionary.
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. 2012-06-05
Heterochrony, broadly defined, refers to evolutionary change in the rate or timing of development. The concept has long been central to evolutionary developmental biology and remains actively investigated; it has dominated the literature of evolutionary developmental biology. Heterochrony describes evolution in the timing of developmental traits and has been an important concept for explanations of phenotypic diversity. Heterochronic processes have the potential to produce tremendous diversification of forms by varying the ontogenetic timing and rate of trait development.

heterochrony that have often been high-lighted since Gould's (1977) grand analysis of the concept: (1) many other changes in evolution are not caused by heterochrony, and therefore heterochrony must remain an operational concept that formulates testable hypotheses for each single case rather than become an empty truism; and (2) hetero-

Heterochrony, evolutionary change in developmental rate or relative timing of developmental events, plays a key role in the transformation of morphology in evolutionary time [1–5] and can play an important role in both the origin and evolutionary diversification of complex phenotypes [6, 7].

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.
