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. 2013-05-02 · Background Autism is usually conceptualized as a disorder or disease that involves fundamentally abnormal neurodevelopment. In the present work, the hypothesis that a suite of core autism-related traits may commonly represent simple delays or non-completion of typical childhood developmental trajectories is evaluated.

In evolutionary developmental biology, heterochrony is any genetically controlled difference in the timing or duration of a developmental process in an organism compared to its ancestors or other organisms.

2012-06-05 · 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.

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.

The concept has long been central to evolutionary developmental biology and remains actively investigated; it has dominated the literature of evolutionary developmental biology. Heterochrony can be defined as “change to the timing or rate of developmental events, relative to the same events in the ancestor” (Alberch et al.

In evolutionary developmental biology, heterochrony is any genetically controlled difference in the timing or duration of a developmental process in an organism compared to its ancestors or other organisms. This leads to changes in the size, shape, characteristics and even presence of certain organs and features.

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. Foucault thought of archives, libraries, Heterochrony refers to an alteration in time, or a change in order, of one or more events. There are various types of heterochronic alterations. For example, paedomorphosis describes a condition in which the timing of sexual maturity is altered (compared to the parental group). Heterochrony refers to the change in the timing and rate of developmental events, and it is a widespread feature in amphibian evolution, particularly in salamanders. During development, a structure can begin to develop sooner (predisplacement) or later (postdisplacement) in an organism than it occurred in the ancestral species or parents.
