In 1859 Charles Darwin published The Origin of Species by Means of Natural Selection. No single book before or since has had such a profound effect on evolutionary theory. To most present-day
The genetic architecture of heterochrony as a quantitative trait: lessons from a computational model 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, that is, evolutionary changes in the relative timing of developmental events and processes, has emerged as a key concept that links evolution and development. Genes associated with heterochrony encode molecular components of developmental timing mecha-nisms. However, our understanding of how heterochrony genes alter the expression Consequently, heterochrony applied to such forms cannot result in evolutionary change in shape.

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 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.
