Morphological innovation through gene regulation: an example from Devonian Onychodontiform fish.
- BiologyThe International journal of developmental biology
- 2006
The study of the new functional structures and the areas from which they were derived by changes in gene regulation, would give us more evolutionary information.
Whole-genome duplication in teleost fishes and its evolutionary consequences
- BiologyMolecular Genetics and Genomics
- 2014
It is likely, however, that TS-WGD provided teleosts with diversification potential that can become effective much later, such as during phases of environmental change.
Molecular origins of rapid and continuous morphological evolution
- BiologyProceedings of the National Academy of Sciences of the United States of America
- 2004
A comparative genomic study of repetitive elements in developmental genes of 92 breeds of dogs finds evidence for selection for divergence at coding repeat loci in the form of both elevated purity and extensive length polymorphism among different breeds.
Conservation and co-option in developmental programmes: the importance of homology relationships
- BiologyFrontiers in Zoology
- 2005
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.
Fossils, genes, and the origin of novelty
- BiologyPaleobiology
- 2000
Advances in the understanding of the mechanistic basis of animal development offer the opportunity to deepen the insight into the nature of the Cambrian explosion, as well as understanding the mechanisms behind the production of morphological variation.
Retracted: Gene duplication and functional evolution of Hox genes in fishes.
- BiologyJournal of fish biology
- 2008
The authors have focused on broadly outlining the duplication of Hoxgenes in fishes and discussing how comparative genomics is elucidating the molecular changes associated with the evolution of H Cox genes expression and developmental function in the teleost fishes.
Fossils, genes, and the origin of novelty
- Biology
- 2000
Advances in the understanding of the mechanistic basis of animal development offer the opportunity to deepen the insight into the nature of the Cambrian explosion and bridge the gap between microevolution and macroevolution.
THE LOCUS OF EVOLUTION: EVO DEVO AND THE GENETICS OF ADAPTATION
- BiologyEvolution; international journal of organic evolution
- 2007
There is no theoretical or empirical basis for the evo devo contention that adaptations involving morphology evolve by genetic mechanisms different from those involving physiology and other traits, and substantial data on the genetic basis of adaptation from both genome-wide surveys and single-locus studies are examined.
The Hox Paradox: More complex(es) than imagined.
- BiologyDevelopmental biology
- 2002
The understanding of Hox cluster architecture in different vertebrates is reviewed and the implications of gene duplication for Hox gene regulation and function and the evolution of different body plans are considered.

A role of Ultrabithorax in morphological differences between Drosophila species
- BiologyNature
- 1998
Experimental evidence is provided that cis-regulatory evolution is one way in which conserved proteins have promoted morphological diversity in Drosophila melanogaster.
Hox genes, homeosis and the evolution of segment identity: no need for hopeless monsters.
- BiologyThe International journal of developmental biology
- 1998
This work argues for a revised model for the role and regulation of the Hox genes, that provides alternative mechanisms for evolutionary change, that may lead to incremental changes in segment morphology.
Hox genes in brachiopods and priapulids and protostome evolution
- BiologyNature
- 1999
It is shown that the complement of Hox genes in critical protostome phyla reflects these phylogenetic relationships and reveals the early evolution of developmental regulatory potential in bilaterians.
Early animal evolution: emerging views from comparative biology and geology.
- BiologyScience
- 1999
The Cambrian appearance of fossils representing diverse phyla has long inspired hypotheses about possible genetic or environmental catalysts of early animal evolution. Only recently, however, have…
MORPHOLOGICAL VARIATION IN THE LIMBS OF TARICHA GRANULOSA (CAUDATA: SALAMANDRIDAE): EVOLUTIONARY AND PHYLOGENETIC IMPLICATIONS
- BiologyEvolution; international journal of organic evolution
- 1995
Variation in the limb skeleton was studied in a large sample of adult newts (Taricha granulosa) from a single population in central California, revealing the potential of the generative system and suggesting the existence of limited domains of phenotypic expression.
Hox gene expression in teleost fins and the origin of vertebrate digits
- BiologyNature
- 1995
A scheme for the fin–limb transition in which the distal autopods (digits) are neomorphic structures produced by unequal proliferation of the posterior part of an ancestral appendix is suggested.
Potential variance affecting homeotic Ultrabithorax and Antennapedia phenotypes in Drosophila melanogaster.
- BiologyGenetics
- 1999
It is argued that the existence of "potential" variance, which is genetic variation whose effects are not observable in wild-type individuals, is a prerequisite for the uncoupling of genetic from phenotypic divergence.
Axial variation in the threespine stickleback: genetic and environmental factors
- Biology
- 1999
It is demonstrated that considerable genetic variation for axial morphology is maintained in natural populations of threespine stickleback, and that differences between populations may be brought about rapidly by changes in frequency of alleles that have coordinated effects along the body axis.
The limits of selection during maize domestication
- BiologyNature
- 1999
The results help to explain why maize is such a variable crop, and suggest that maize domestication required hundreds of years, and confirm previous evidence that maize was domesticated from Balsas teosinte of southwestern Mexico.
