Abstract A synthesis of developmental genetics with evolutionary genetics is now making possible to understand significant evolutionary changes in multicellular organisms. The key concept for unifying the two must be heterochrony. Heterochrony causes evolutionary modifications due to changes in timing and/or rate of development. The heterochrony is conventionally categorized into three patterns as neoteny (retardation in somatic development), progenesis (acceleration in gonadal development…

Heterochrony and allometry: the analysis of evolutionary change in ontogeny

  • C. Klingenberg

This review examines how several methodological frameworks to analyse heterochrony compare ancestral and descendant ontogenies, emphasizing their differences and the potential for contradictory results from analyses using different frameworks.

Arrested development in Xenopus laevis tadpoles: how size constrains metamorphosis

SUMMARY Xenopus laevis tadpoles that arrest development and remain as larvae for several years sometimes occur spontaneously in laboratory populations. These tadpoles cease development at an early

Development and gonadal sex differentiation in the neotenic urodele: Ambystoma mexicanum

The observations and the way these correlate with other urodeles suggest that gonadal morphogenesis in A. mexicanum does not depend on larval age and is completely independent of metamorphosis, implying a process of heterochrony.

P450 aromatase expression in the temperature-sensitive sexual differentiation of salamander (Hynobius retardatus) gonads.

The results confirm the importance of the P450arom regulation in the sexual differentiation of gonads and demonstrate that an up-regulation of P 450arom is involved in the process of temperature-sensitive sex reversal in this species.

Erythropoiesis and unexpected expression pattern of globin genes in the salamander Hynobius retardatus

The pattern of globin gene expression in metamorphosis-arrested larvae was almost identical to that in normal controls, suggesting that the transition occurs independently of thyroid hormones, and in larvae recovering from anemia, precocious Hb transition did not occur in H. retardatus.

Histological study of karaurids, the oldest known (stem) urodeles

Bone histology reveals that the growth of Marmorerpeton and the related unnamed caudate was fairly slow and cyclic, a characteristic of extant lissamphibians, and strengthens the case for the presence of neoteny in these taxa.

Larvae in A * phibian Development and Evolution

The tremendous intellectual excitement and activity that have attended the study of the relation between development and evolution over the past 20-25 years rival those characteristic of the "Golden

The possible contribution of pituitary hormones to the heterochronic development of gonads and external morphology in overwintered larvae of Hynobius retardatus.

The results suggest that gonadal development proceeds gradually with age even in the overwintered larvae, but that metamorphosis is retarded, probably due to the larvae's cold habitat.

Osteology of Batrachuperus londongensis (Urodela, Hynobiidae): study of bony anatomy of a facultatively neotenic salamander from Mount Emei, Sichuan Province, China

A detailed osteological account of B. londongensis is provided based on micro-CT scanning and clearing and staining of multiple specimens from the type locality and a discussion of intraspecific variation related to life-history differences is presented.



Heterochrony and the phylotypic period.

The morphological data relating to developmental timing in somite-stage embryos are reexamined and reveal striking patterns of heterochrony during vertebrate evolution.

It is argued that temporal colinearity only occurs in cells with high mitotic rates, which results in a strong linkage between patterning and growth control and makes the patterning process unidirectional, from anterior, proximal and early, to posterior, distal and late, a model referred to as the 'Einbahnstrasse'.

Heterochrony: Developmental mechanisms and evolutionary results

The objective is to redefine heterochrony more broadly so that the concept becomes readily applicable to the evolution of the full range of ontogenetic processes, from embryogenesis through the adult.

Genie Control of Axolotl Metamorphosis

Neoteny in the Mexican axolotl, Ambystoma mexicanum, is caused by homozygosity for a single recessive gene, and can be induced precociously by immersion of the larvae in low concentrations of thyroxine or with higherthyroxine concentrations.

Resynthesizing evolutionary and developmental biology.

A new and more robust evolutionary synthesis is emerging that attempts to explain macroevolution as well as microevolutionary events, and the morphogenetic field is seen as a major unit of ontogeny whose changes bring about changes in evolution.

Heterochronic mechanisms of morphological diversification and evolutionary change in the neotropical salamander, Bolitoglossa occidentalis (Amphibia: Plethodontidae)

This result supports Alberch's ('80a) prediction, based on functional analysis, that the principle adaptation to arboreality in B. occidentalis is small size; other derived morphological features are associated with the organism's truncated development and may have no adaptive significance.

The Mexican Axolotl, Ambystoma mexicanum: Its Biology and Developmental Genetics, and Its Autonomous Cell-lethal Genes

The Mexican axolotl, a neotonous salamander, has found widespread use as an experimental animal for studies in embryology and physiology and the high quality of the eggs it produces contribute to its popularity in laboratory research.

Developmental Biology of the Axolotl

This book discusses the discovery of the axolotl and its early history in biological research, its relationship to the salamander, developmental biology, and practical information on working with axolOTls.

Heterochronic mutants of the nematode Caenorhabditis elegans.

The identification and characterization of genes that can be mutated to cause heterochrony support the proposal that heterochronsy is a mechanism for phylogenetic change and suggest cellular and genetic bases for heterochronic variation.

Recent advances in our understanding of the temporal control of early embryonic development in amphibians.

Recent studies on temporal control of early amphibian development are reviewed, finding several developmental events, particularly those associated with transcriptional activities, require DNA replication prior to their occurrence, suggesting an intimate relationship between DNA replication cycles and their onset.
