refers to changes in the pace of development, or timing and order of important steps in development, while the animal is still growing as an embryo and a juvenile.
: an unappreciated key to angiosperm origins and diversification.
The analysis of ontogenetic trajectories: When a change in size or shape is not heterochrony
. Proceedings of the National Academy of Science, 94, 907-912.
The narrator's full realization and its contingent delineations of the multiple and heterodox temporal status of Marco's journey thus can be understood through the Bakhtinian concept of 'heterochrony
' where a given moment in the present is crammed with many simultaneously coexisting, heterochronous temporal possibilities such that our experience and understanding of time enters the conglomerate realm of "pluritemporality" (Cromphout 168).
Gilbert claims that the classical modes of evolutionary developmental biology (i.e., heterotypy, heterochrony
, heterometry, and heterotopy) supplement and extend the Modern Synthesis, but symbiotic and epigenetic contributions could be more revolutionary (p.
helped dethrone recapitulation as biology's grand narrative, undermining the scientific justification of old hierarchies and prejudices.

during skeletal development of Pseudis platensis (Anura, Hylidae) and the early offset of skeleton development and growth.
Analysis of morphological changes in ancestral and descendant taxa and comparison between modern groups may indicate the presence of heterochrony
(i.e., change in time or rate of events during development) and reveal whether the differences are the result of paedomorphosis or peramorphosis (Klingenberg, 1998).
Directional macroevolution of the diplograptid of the diplograptacean graptolites: a product of astogenetic heterochrony
and directed speciation.
The ability to exhibit such heterochrony
in life history processes has played an important role in the evolution of many groups of salamanders, including the members of the Ambystomatidae, and more specifically, certain members of the tiger salamander complex (Collins, 1981; Routman, 1993; Whiteman et al., 1996).
