  • Polyploidy and Sex Chromosome Evolution in Amphibians
    Chapter 18 Polyploidization and Sex Chromosome Evolution in Amphibians Ben J. Evans, R. Alexander Pyron and John J. Wiens Abstract Genome duplication, including polyploid speciation and spontaneous polyploidy in diploid species, occurs more frequently in amphibians than mammals. One possible explanation is that some amphibians, unlike almost all mammals, have young sex chromosomes that carry a similar suite of genes (apart from the genetic trigger for sex determination). These species potentially can experience genome duplication without disrupting dosage stoichiometry between interacting proteins encoded by genes on the sex chromosomes and autosomalPROOF chromosomes. To explore this possibility, we performed a permutation aimed at testing whether amphibian species that experienced polyploid speciation or spontaneous polyploidy have younger sex chromosomes than other amphibians. While the most conservative permutation was not significant, the frog genera Xenopus and Leiopelma provide anecdotal support for a negative correlation between the age of sex chromosomes and a species’ propensity to undergo genome duplication. This study also points to more frequent turnover of sex chromosomes than previously proposed, and suggests a lack of statistical support for male versus female heterogamy in the most recent common ancestors of frogs, salamanders, and amphibians in general. Future advances in genomics undoubtedly will further illuminate the relationship between amphibian sex chromosome degeneration and genome duplication. B. J.

Smith 1, 2* & Jean-Bernard Caron 2, 1 1Departent of Ecology and Evolutionary Biology, University of Toronto, 25 Harbord Street, Ontario, M5S 3G5, Canada 2Department of Palaeobiology, Royal Ontario Museum, 100 Queen ’s Park, Toronto, Ontario M5S 2C6, Canada *Author for correspondence The exquisite preservation of soft-bodied animals in Burgess Shale-type deposits provides important clues into the early evolution of body plans that emerged during the Cambrian explosion 1. Until now, such deposits have remained silent regarding the early evolution of extant molluscan lineages – in particular the cephalopods. Nautiloids, traditionally considered basal within the cephalopods, are generally depicted as evolving from a creeping Cambrian ancestor whose dorsal shell afforded protection and buoyancy 2. Whilst nautiloid-like shells occur from the Late Cambrian onwards, the fossil record provides little constraint on this model, or indeed on the early evolution of cephalopods. Here, we reinterpret the problematic Middle Cambrian animal Nectocaris pteryx 3, 4 as a primitive (i.e. stem-group), non-mineralized cephalopod, based on new material from the Burgess Shale. Together with Nectocaris, the problematic Lower Cambrian taxa Petalilium 5 and (probably) Vetustovermis 6, 7 form a distinctive clade, Nectocarididae, characterized by an open axial cavity with paired gills, wide lateral fins, a single pair of long, prehensile tentacles, a pair of non-faceted eyes on short stalks, and a large, flexible anterior funnel.

Main morphological innovations in the evolution of nautiloid cephalopods; the formation of endosiphuncular and cameral deposits, shell coiling, truncation of the phragmocone’s apical end, and contracted aperture, which originated to make the relative shell positioning in the water more efficient. Changes in the lobe line structure and various types of complications in the primary lobes (ventral, umbonal, and lateral) were the most important morphological innovations in convolute ammonoids. The functional significance of these changes remains unclear, but recognition of equally significant changes in primary lobes requires a review of the Paleozoic Ammonoidea taxonomy at the suborder level. This paper is a continuation of a study whose first lation of the buoyancy process and to support in various results have been published (Barskov et al., 1993).

  • The Early History of the Metazoa—A Paleontologist's Viewpoint

Zhuravlev Geological Institute, Russian Academy of Sciences, per. Pyzhevsky 7, Moscow, 7119017 Russia email: [email protected] Received January 21, 2014 Abstract—Successful molecular biology, which led to the revision of fundamental views on the relationships and evolutionary pathways of major groups (“phyla”) of multicellular animals, has been much more appre ciated by paleontologists than by zoologists. This is not surprising, because it is the fossil record that provides evidence for the hypotheses of molecular biology. The fossil record suggests that the different “phyla” now united in the Ecdysozoa, which comprises arthropods, onychophorans, tardigrades, priapulids, and nemato morphs, include a number of transitional forms that became extinct in the early Palaeozoic. The morphology of these organisms agrees entirely with that of the hypothetical ancestral forms reconstructed based on onto genetic studies. No intermediates, even tentative ones, between arthropods and annelids are found in the fos sil record. The study of the earliest Deuterostomia, the only branch of the Bilateria agreed on by all biological disciplines, gives insight into their early evolutionary history, suggesting the existence of motile bilaterally symmetrical forms at the dawn of chordates, hemichordates, and echinoderms. Interpretation of the early history of the Lophotrochozoa is even more difficult because, in contrast to other bilaterians, their oldest fos sils are preserved only as mineralized skeletons.
