One of the most persistent questions in comparative developmental biology concerns
whether there are general rules by which ontogeny and phylogeny are related. Answering …

The concept of heterochrony is a persistent component of discussions about the way that
evolution and development interact. Since the late 1970s heterochrony has been defined …

Heterochrony, change in developmental rate and timing, is widely recognized as an agent of
evolutionary change. Heterotopy, evolutionary change in spatial patterning of development …

The concept of heterochrony, that the relative timing of ontogenetic events can shift during
evolution, has been a major paradigm for understanding the role of developmental …

The concept of heterochrony, which denotes a change in the relative timing of
developmental events and processes in evolution, has accompanied attempts to link …

Heterochrony is evolution via change in timing (and/or rate) of development. However, this
oft-repeated definition threatens to dull by repetition the important fact that virtually all …

Heterochrony, defined as a change in the timing of developmental events altering the course
of evolution, was first recognized by Ernst Haeckel in 1866. Haeckel's original definition was …

The connection between development and evolution has become the focus of an increasing
amount of research in recent years, and heterochrony has long been a key concept in this …

While a framework and terminology for heterochrony has been referenced widely in the
literature and appears to be accepted by nearly all workers in the field we have found it to be …

Heterochrony, evolutionary changes in developmental timing, can be studied either by
examining changes in growth or changes in the sequence of developmental events …
