BACKGROUND A surprising amount of developmental variation has been observed for otherwise highly conserved features, a phenomenon known as developmental system drift. Either stochastic processes (e.g., drift and absence of selection-independent constraints) or deterministic processes (e.g., selection or constraints) could be the predominate mechanism for the evolution of such variation. We tested whether evolutionary patterns of change were unbiased or biased, as predicted by the stochastic or… Expand

  • 2012
TLDR
Comparison of vulva development between Caenorhabditis elegans and the evo-devo model Pristionchus pacificus is compared and redundancy is discussed as an evolutionary mechanism to explain developmental systems drift. Expand
Robustness and flexibility in nematode vulva development.
TLDR
An emerging direction in the field is discussed, which places vulva research in a quantitative and microevolutionary framework, which indicates that the developmental system has accumulated cryptic variation, even among wild C. elegans isolates. Expand
Patterns of Molecular Evolution in Caenorhabditis Preclude Ancient Origins of Selfing
TLDR
It is concluded that the profound changes in mating behavior, physiology, and developmental mechanisms that accompanied the transition from an obligately outcrossing to a primarily selfing mode of reproduction evolved in the not-too-distant past. Expand
Nematode model systems in evolution and development
TLDR
This article introduces selected model systems for nematode evo‐devo and provides a detailed discussion of four selected case studies, highlighting the importance of developmental systems drift and neutrality in evolution. Expand
The nematode Pristionchus pacificus as a model system for integrative studies in evolutionary biology
TLDR
Recent attempts to establish the nematode Pristionchus pacificus as a model organism that allows integrative studies of development and evo‐devo, with ecology and population genetics are reviewed. Expand
RAPID DECLINE IN FITNESS OF MUTATION ACCUMULATION LINES OF GONOCHORISTIC (OUTCROSSING) CAENORHABDITIS NEMATODES
TLDR
The results suggest that natural selection operates to optimize the mutation rate in Caenorhabditis and that the strength (or efficiency) of selection differs consistently on the basis of mating system, as predicted by theory. Expand
Comparative and phylogenetic analysis of the early embryonic development in the phylum Nematoda
TLDR
A comparative analysis of the early embryonic development of nematode species belonging to clade 6 and clades 9-12 revealed prominent differences between nematodes and ancestral state reconstructions of these characters onto a molecular phylogeny revealed four synapomorphies. Expand
Evolution of early embryogenesis in rhabditid nematodes.
TLDR
This work systematically investigated early embryogenesis, from the one- to the four-cell embryo, in 34 nematode species related to C. elegans, finding 40 cell-biological characters that captured the phenotypic differences between these species and tracing the evolutionary changes on a molecular phylogeny found that these characters evolved multiple times and independently of one another. Expand
Cryptic genetic variation uncovers evolution of environmentally sensitive parameters in Caenorhabditis vulval development
TLDR
This work disrupted vulval patterning using thermal perturbations to quantify and compare environmental sensitivity of different system parameters between distinct genotypes of C. elegans and C. briggsae and shows how sensitivity of system parameters regulating Caenorhabditis vulval development depends on subtle interactions between perturbation and genetic background. Expand
Bias and Evolution of the Mutationally Accessible Phenotypic Space in a Developmental System
TLDR
An empirical assessment of developmental bias and the evolution of mutationally accessible phenotypes supports the notion that such bias may influence the directions of evolutionary change and identifies the mutationally most sensitive elements of the vulval developmental system, which may indicate axes of potential evolutionary variation.

Evolution of cell lineage and pattern formation in the vulval equivalence group of rhabditid nematodes.
TLDR
This work has analyzed cell lineages and pattern formation in the vulva equivalence group of six rhabditid nematodes of the genera Oscheius, Rhabditella, R Habditoides, Pelodera, and Protorhabditis, and reveals evolutionary modification at several levels. Expand
Developmental system drift and flexibility in evolutionary trajectories
TLDR
Current data on the population genetics and molecular mechanisms of DSD illustrate how the details of developmental processes are constantly changing within evolutionary lineages, indicating that developmental systems may possess a great deal of plasticity in their responses to natural selection. Expand
Apoptosis and change of competence limit the size of the vulva equivalence group in Pristionchus pacificus: a genetic analysis
TLDR
The phenotypes of Pristionchus mutants suggest that alterations in homeotic gene control of anteroposterior patterning is involved in creating this cellular diversity. Expand
Evolution of vulva development in the Cephalobina (Nematoda).
TLDR
The first example of a vulval cell lineage that is asymmetric between the anterior and the posterior sides of the vulva is described, and it is concluded that in this group, death of the Pn.p cells probably constitutes a derived character state compared to a syncytial fate. Expand
Evolutionary changes of developmental mechanisms in the absence of cell lineage alterations during vulva formation in the Diplogastridae (Nematoda).
TLDR
The results suggest that developmental mechanisms, some of which are redundantly involved in vulval fate specification of the genetic model organism Caenorhabditis elegans, can evolve without concomitant morphological change. Expand
Microevolutionary analysis of the nematode genus Pristionchus suggests a recent evolution of redundant developmental mechanisms during vulva formation
TLDR
The molecular and developmental characterization of laboratory strains of the nematode genus Pristionchus are described, which lays a foundation for a microevolutionary analysis of vulva development. Expand
Polymorphism and evolution of vulval precursor cell lineages within two nematode genera, Caenorhabditis and Oscheius
TLDR
Polymorphisms in vulval cell lineage are found within a given nematode species, and could be instrumental in explaining evolutionary variations between closely related species. Expand
Conservation and diversification of Wnt signaling function during the evolution of nematode vulva development
Cell-fate specification and cell-cell signaling have been well studied during vulva development in Caenorhabditis elegans and provide a paradigm in evolutionary developmental biology. Pristionchus… Expand
Gonadogenesis in Pristionchus pacificus and organ evolution: development, adult morphology and cell-cell interactions in the hermaphrodite gonad.
TLDR
It is reported that the morphology of the P.pacificus gonad is distinct from that of C. elegans, and a set of cell ablations in P. pacificus that indicate extensive cell communication between the somatic gonadal tissues and the germ line. Expand
Developmental Constraints and Evolution: A Perspective from the Mountain Lake Conference on Development and Evolution
TLDR
This review distinguishes between "universal" and "local" constraints; it deals primarily with the latter, which apply to a limited range of taxa and can be broken even within the taxa to which they apply, though with varying degrees of difficulty. Expand
