  Evolutionary developmental biology - Wikipedia, the free encyclopedia
Evolutionary developmental biology (evolution of development or informally, 'evo-devo') is a field of biology that compares the developmental processes of different animals in an attempt to determine the ancestral relationship between organisms and how developmental processes evolved.
Among the more surprising and, perhaps, counter-intuitive results of such research in evolutionary developmental biology done in this period is that the diversity of body plans and morphology in organisms across many phyla are not necessarily reflected in diversity at the level of the sequences of genes involved in the regulation of development.
The discovery of the homeotic Hox gene family in vertebrates in the 1980s allowed researchers in developmental biology to empirically assess the relative roles of the above two factors, with respect to their importance in the evolution of morphological diversity.

Evolutionary developmental biology (often referred to as 'evo-devo' or evolution of development) is a field of biology that compares the developmental processes of different animals in an attempt to determine the ancestral relationship between organisms and how developmental processes evolved.
Evolutionary developmental biology has arisen as a response to these growing trends.
One of the more suprising and perhaps, counter-intuitive, results of such research in evolutionary developmental biology done in this period, is that both the diversity of body plans and morphology in organisms across many phyla is not necessarily reflected in similar diversity at the at the level of the genetic sequences controlling development.

The merging of the developmental genetic approach to evolution ('evo- devo') with the population genetic approach is creating a more complete evolutionary biology that is beginning to explain the origin of both species and higher taxa...
This evolutionary developmental biology, or "evo-devo", is focused on the developmental genetic machinery that lies behind embryological phenotypes, which were all that could be studied in the past.
In view of the current widespread interest in evolutionary developmental biology, and especially in the conservation of developmental mechanisms, re-examination of the extent of variation in vertebrate embryos is long overdue.

The new field of evolutionary developmental biology is one of the most exciting areas of contemporary biology.
The fundamental principle of evolutionary developmental biology ("evo-devo") is that evolution acts through inherited changes in the development of the organism.
"Evo-devo" is not merely a fusion of the fields of developmental and evolutionary biology, the grafting of a developmental perspective onto evolutionary biology, or the incorporation of an evolutionary perspective into developmental biology.

 Principles of Developmental Biology
On the one hand, the developmental program must be robust and produce the same morphology for adult members of a species every time.
Modern studies of evolutionary developmental biology investigate how individual genes, gene networks, signaling pathways, life histories, and embryology may generate novelty.
Finally, in some groups novelties arise by invention of new developmental trajectories, as in the case of neural crest cells, which are uniquely found in vertebrates.

The idea that embryology, as developmental biology was then known, reveals important truths about evolution also played a big part in the first real revolution in evolutionary thought: Darwinism.
By the second revolution in evolutionary thought—the so-called Modern Synthesis of the nineteen-thirties and forties, when Darwin’s theory of evolution was fused with Mendel’s theory of genetics—development was left out in the cold.
And the Modern Synthesis, the second defining moment in the history of evolutionary biology, came close: it’s hard to think of evolution in the same way once you know that it has to obey the laws of Mendel’s genetics.

Evolutionary developmental biology -- The evolution of body form requires not only that genes evolve, but that development from egg to adult also evolves.
We are focusing on the aspects of gene organization and expression that underlie the differences in cell cleavage, cell lineage, timing of developmental events, and morphogenetic processes between these species.
We have isolated several such genes, and we are studying their roles in the evolution of development by experimentally manipulating the expression of these genes in sea urchin embryos.

If the resynthesis of development and evolution is to be more than a passing fad, a dialogue must establish the questions and types of disciplinary integration that make the evo-devo enterprise a distinct field rather than a loose amalgamation of approaches ranging from paleontology to genomics.
I propose to contribute to the dialogue by identifying a set of goals of evolutionary developmental biology and the questions they engender.
I will start from the premise that developmental biology is about coordination at molecular, cellular, tissue and organ levels of organisation.

Morphological structures are produced by growth, and their form emerges from the process of development.
Thus evolutionary changes in the form of an organ are frequently developmental: they are produced by changes in the rate or timing of developmental events.
An organ may evolve to be larger if its growth speeds up, and it may change shape if the growth rate of one of its parts speeds up relative to other parts.
