Although genes have specific phenotypic consequences in a given species, this functional relationship can clearly change during the course of evolution. Many cases of evolutionary dissociations between homologous genes and homologous morphological features are now known. These dissociations have interesting and important implications for understanding the genetic basis for evolutionary change in morphology.

Evolutionary Developmental Biology: Homologous Regulatory Genes and
Traits in two species are classed as homologous when they are derived from a similar trait in a shared ancestor. Homology can exist at the levels of both anatomical structure and regulatory gene… Expand
The developmental genetics of homology
  • G. Wagner
  • Biology, Medicine
  • Nature Reviews Genetics
  • 2007
TLDR
It is proposed that it is the historical continuity of gene regulatory networks rather than the expression of individual homologous genes that underlies the homology of morphological characters. Expand
Deep homology: A view from systematics
  • R. Scotland
  • Biology, Medicine
  • BioEssays : news and reviews in molecular, cellular and developmental biology
  • 2010
TLDR
Four examples – three from plants and one from animals – demonstrate that homologous developmental mechanisms can regulate a range of morphological relations including analogy, homoplasy and examples of uncertain homology. Expand
The Role of Developmental Genetics in Understanding Homology and Morphological Evolution in Plants
TLDR
This work examines the role of APETALA3 and PISTILLATA homologs in the development of petaloid organs, and provides some guidelines for the critical examination of comparative gene expression data in the context of studying morphological innovations. Expand
Evolutionary Developmental Biology: Homologous Regulatory Genes and Processes
TLDR
Developmental genes provide a new way to identify homologous structures in animals by showing that both structures are specified by the same set of regulatory genes. Expand
Birth, life and death of developmental control genes: New challenges for the homology concept
  • G. Theißen
  • Medicine, Computer Science
  • Theory in Biosciences
  • 2008
TLDR
This article opts for a careful use of a limited and well-chosen set of terms describing gene relationships and function, rather than the inflationary production of novel terms that may seem to be precise, but whose obscurity hampers communication. Expand
Birth, life and death of developmental control genes: new challenges for the homology concept.
TLDR
This article opts for a careful use of a limited and well-chosen set of terms describing gene relationships and function, rather than the inflationary production of novel terms that may seem to be precise, but whose obscurity hampers communication. Expand
Conservation and co-option in developmental programmes: the importance of homology relationships
TLDR
It is of great interest to examine whether the widespread conservation of the genetic machinery implies the same developmental function in a last common ancestor, or whether homologous genes acquired new developmental roles in structures of independent phylogenetic origin. Expand
Homology and ontogeny: pattern and process in comparative developmental biology
  • G. Scholtz
  • Medicine, Computer Science
  • Theory in Biosciences
  • 2008
TLDR
There is no ontogenetic homology “criterion”, the interface between development and homology is discussed, and a homology definition which includes similarity and complexity serves as a test for homology. Expand
Homology and ontogeny: pattern and process in comparative developmental biology.
TLDR
There is no ontogenetic homology "criterion" because corresponding positions are not necessarily indicative of homology, and topology as a test for homology is critically discussed. Expand

TLDR
It is argued that although developmental genetic data can help identify homologous structures, they are neither necessary nor sufficient, and do not in any case justify a new definition of homology. Expand

TLDR
The lack of a simple and consistent relationship between homologous genes and structures has important implications for understanding correlations between evolutionary changes at different levels of biological organization. Expand

TLDR
The comparative analysis of traits derived from several hierarchical levels can potentially reveal scenarios of developmental integration, opportunity and constraint and has implications for resolving modern controversies surrounding the concept of homology. Expand
Molecules and morphology: where's the homology?
TLDR
Some recent suggestions notwithstanding v7, molecular similarities in the developmental mechanisms that produce specific organs are not, by themselves, strong evidence for homology of those organs. Expand

Comparative molecular developmental biology is providing new insight into the similarities and differences in the morphologies of these homologous structures. Expand

The origin and diversification of fins, wings and other structures, long a focus of palaeontology, can now be approached through developmental genetics. Expand
Mutations affecting segment number and polarity in Drosophila
TLDR
The phenotypes of the mutant embryos indicate that the process of segmentation involves at least three levels of spatial organization: the entire egg as developmental unit, a repeat unit with the length of two segments, and the individual segment. Expand
Pair-rule expression patterns of even-skipped are found in both short- and long-germ beetles
TLDR
Examination of the expression of even-skipped in a variety of insects reveals that insect germ-type designations apparently do not reflect the variations in the mechanisms of segmentation evident throughout insect phylogeny. Expand
The evolution of 'bricolage'.
TLDR
It is argued that animal diversity might largely rely on the differential use of the same components, either at the individual level through divergent functional recruitment, or at a more integrated level, through their participation in various genetic networks. Expand
Did homeodomain proteins duplicate before the origin of angiosperms, fungi, and metazoa?
TLDR
The hypothesis that there was at least one duplication of homeobox genes before the origin of angiosperms, fungi, and metazoa is supported and suggests that these proteins had diverse functions early in the evolution of eukaryotes. Expand
