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 . 1999-01-01 · This chapter discusses heterochrony, which is an ancestor–descendant difference in the relative timing of events during development. This phylogenetic pattern frequently has been confused with ecological and evolutionary processes that result in diverse larval forms that also vary in the timing of developmental events.

Heterochrony is an important mechanism in the evolution of amphibians. Although studies have centered on the relationship between size and shape and the rates of development, ossification sequence heterochrony also may have been important.
