Abstract The idea that the last common ancestor of bilaterian animals (Urbilateria) was segmented has been raised recently on evidence coming from comparative molecular embryology. Leaving aside the complex debate on the value of genetic evidence, the morphological and developmental evidence in favor of a segmented Urbilateria are discussed in the light of the emerging molecular phylogeny of metazoans. Applying a cladistic character optimization procedure to the question of segmentation is… 
Acoel development supports a simple planula-like urbilaterian
  • A. Hejnol, M. Martindale
  • Biology, Medicine
    Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2008
TLDR
It is argued that this animal, with features resembling acoelomorph flatworms, was far simpler morphologically than the protostome–deuterostome ancestor despite possessing a nearly complete eubilaterian genome.
An integrated view of precambrian eumetazoan evolution.
TLDR
A strong conclusion is that the evolutionary process generating the genomic programs responsible for developmental formulation of basic eumetazoan body plans was in many ways very different from the evolutionary changes that can be observed at the species level in modern animals.
Evolution of the bilaterian germ line: lineage origin and modulation of specification mechanisms.
  • C. Extavour
  • Biology, Medicine
    Integrative and comparative biology
  • 2007
TLDR
The present article examines the comparative data available to date on the specification of the only cells containing the genetic hereditary material, the germ cells, and speculates on the possible evolutionary and developmental origin of the Urbilaterian germ line.
Gray anatomy: phylogenetic patterns of somatic gonad structures and reproductive strategies across the Bilateria.
  • C. Extavour
  • Biology, Medicine
    Integrative and comparative biology
  • 2007
TLDR
It is concluded that the data presently available cannot suggest homologies of the somatic components of metazoan gonads, and that convergent evolution has resulted in many different morphological and possibly molecular genetic solutions to the various problems posed by sexual reproduction.
Segment formation in Annelids: patterns, processes and evolution.
  • G. Balavoine
  • Biology, Medicine
    The International journal of developmental biology
  • 2014
TLDR
The various patterns of evolution of the metameric body plan in annelids are summarized, showing the remarkable evolvability of this trait, similar to what is also found in arthropods.
A metameric origin for the annelid pygidium?
TLDR
The pygidium possesses a complicated nervous system with a nerve ring and a pair of sensory ganglia, a complex intrinsic musculature, a large terminal circular blood sinus and an unusual unpaired torus-shaped coelomic cavity, opening the debate on whether the pyGidium and trunk segments derive from the same ancestral metameric unit.
Early origin of the bilaterian developmental toolkit
  • D. Erwin
  • Biology, Medicine
    Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2009
TLDR
It is suggested that placozoans and cnidarians represent a depauperate residue of a once more diverse assemblage of early animals, some of which may be represented in the Ediacaran fauna (c. 585–542 Myr ago).
Dismissal of Acoelomorpha: Acoela and Nemertodermatida are separate early bilaterian clades
We used new 18S and 28S rRNA sequences analysed with parsimony, maximum likelihood and Bayesian methods of phylogenetic reconstruction to show that Nemertodermatida, generally classified as the
Mechanisms of segmentation in the American cockroach, Periplaneta americana
TLDR
This thesis will explore the conservation and divergence of the molecular mechanisms of segmentation in a phylogenetically basal, short germ band insect, Periplaneta americana (American cockroach), and discuss aspects of cockroach segmentation processes, from the establishment of a posterior organiser and growth zone to subsequent posterior growth and the formation of new segments.
The early history of the metazoa—a paleontologist’s viewpoint
TLDR
In the aggregate, modern data from molecular biology, palaeontology, and comparative embryology/morphology, having been revitalized by the introduction of new microscopy techniques, imply that the hypothesized planktotrophic gastrae-like common ancestor is the least likely of the diverse suggestions on the origins of the Metazoa.

Bilaterian origins: significance of new experimental observations.
TLDR
New data on Hox gene expression patterns are discussed which suggest that both sea urchins and polychaete annelids use Hox genes in a very similar fashion, and the ancestry of the bilaterians is summarized in phylogenetic terms.
A critical reappraisal of the fossil record of the bilaterian phyla
  • G. Budd, S. Jensen
  • Medicine
    Biological reviews of the Cambridge Philosophical Society
  • 2000
TLDR
It is shown that the prospect of lineage diversification occurring early in the Proterozoic can be seen to be unlikely on grounds of both parsimony and functional morphology, and this analysis points to the requirement for a careful application of systematic methodology before explanations are sought for alleged patterns of constraint and flexibility.

SUMMARY Segmentation as an attribute of organisms is being increasingly discussed in the recent literature because (1) new phylogenies suggest that organisms classically considered to be segmented
Are Platyhelminthes Coelomates without a Coelom? An Argument Based on the Evolution of Hox Genes'
TLDR
Arguments from 18S rDNA and Hox gene evolution are reviewed in favor of a late emergence of at least the rhabditophoran platyhelminths and flatworms can be convincingly grouped with the spiralian coelomate protostomes.
Hox genes in brachiopods and priapulids and protostome evolution
TLDR
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.
Unsegmented Annelids? Possible Origins of Four Lophotrochozoan Worm Taxa1
TLDR
Abundant molecular, developmental, and morphological data show that the Siboglinidae, which includes the formerly recognized Pogonophora and Vestimentifera, are derived annelids; recent data from the Elongation Factor-1α gene also suggest that echiurids are of annelid ancestry.
Evolution of animal body plans: the role of metazoan phylogeny at the interface between pattern and process
  • R. Jenner

    Evolution & development
  • 2000
TLDR
This work discusses how two recent important studies of animal body plan evolution, examining the evolution of the platyhelminth body plan and the evolutionary significance of indirect development and set‐aside cells, have actively incorporated two problematic aspects of the newly emerging molecular view of animal evolution: incomplete and unresolved phylogenies.
Are Echiura derived from a segmented ancestor? Immunohistochemical analysis of the nervous system in developmental stages of Bonellia viridis
TLDR
Results from an immunohistochemical analysis visualized with confocal laser‐scanning microscopy shows the development of serially repeated units in the nervous system of Bonellia viridis support the systematic inclusion of the Echiura within the Annelida.
Molecular evidence that echiurans and pogonophorans are derived annelids.
  • D. McHugh
  • Biology, Medicine
    Proceedings of the National Academy of Sciences of the United States of America
  • 1997
TLDR
This result, indicating the derived loss of segmentation in echiurans, has profound implications for the understanding of the evolution of metazoan body plans and challenges the traditional view of the phylum-level diversity and evolutionary relationships of protostome worms.
Progenesis as a principle in meiofauna evolution
TLDR
It is emphasized that progenetic evolution is not regressive or degenerate but novel morphological features like derived reproductive organs are characteristic indications of the progenet...
