Heterochrony and the developmental origins of neonatal characteristics of precocial and altircial birds.2006Ingår i: Journal of Ornithology 147 (5),

Heterochrony acts on the different parts of the organism differently (as in the Irish Elk example). If what is being referred to here is something that covers the whole body such as the end of deterministic growth or sexual maturity, then that should be referred to.

Heterochrony refers to the change in the timing and rate of developmental events, and it is a widespread feature in amphibian evolution, One such concept is heterochrony, a term referring to a multifaceted temporality, that art theorist Nicolas Bourriaud claims is common in contemporary art. Such features respond to the environment in the broad sense, that is, when both abiotic and biotic components are included. Newts of the genus Triturus have av O Seehausen · 2002 · Citerat av 120 — The exceptional taxon is a lineage of haplochromine cichlids that is also known for its rapid speciation elsewhere.

In a sense, this is hardly surprising, since changing the rate or time at or during which a trait grows is certainly the simplest way to alter form (McKinney, this volume, Chapter 2). Heterochrony that produces these changes in size and shape may be the link between genetics at one extreme and natural selection at the other. If a character of one species in an evolutionary sequence undergoes less growth than its ancestor, the process is known as pedomorphosis. HETEROCHRONY IN MORE‐INCLUSIVE THERIAN MAMMAL CLADES. The heterochrony at the marsupial–placental dichotomy reported between marsupials and placentals is contrasted by general lack of heterochrony between mammals and sauropsids, and in most major placental clades. Heterochrony can be divided into intraspecific heterochrony, variation within a species, and interspecific heterochrony, phylogenetic variation, i.e. variation of a descendant species with respect to an ancestral species.

The first section of this paper aims to discuss how temporality is handled in Foucault's heterotopias in “Of Other. Spaces” and define what heterochrony means as a an adult poet is simply an individual in a state of arrested development-in brief, a sort of moron.

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 is of interest in part because it can produce novelties constrained along ancestral ontogenies, and hence result in parallelism between ontogeny and phylogeny. Heterotopy can produce new morphologies along trajectories different from those that generated the forms of ancestors.

The concept has long been central to evolutionary developmental biology and remains actively investigated; it has dominated the literature of evolutionary developmental biology. 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. It applies to the time a trait appears in the growth of an organism, or to the timing of gene expression in development. p203 Heterochrony can be divided into intraspecific heterochrony, variation within a species, and interspecific heterochrony, phylogenetic variation, i.e.

In biology, heterochrony is defined as a developmental change in the timing of events, leading to changes in size and shape.
