Deciphering deuterostome phylogeny: molecular, morphological and palaeontological perspectives.
Deuterostomes are a monophyletic group of animals that include the vertebrates, invertebrate chordates, ambulacrarians and xenoturbellids. Fossil representatives from most major deuterostome groups, including some phylum-level crown groups, are found in the Lower Cambrian, suggesting that evolutionary divergence occurred in the Late Precambrian, in agreement with some molecular clock estimates....
متن کاملMolecular phylogeny and divergence times of deuterostome animals.
The phylogenetic relationships among deuterostome animals have been debated for many years, and a diversity of hypotheses have been proposed based on both morphological and molecular data. Here we have assembled sequences of 217 nuclear-encoded proteins to address specific questions concerning their relationships and times of origin. We recovered significant support for urochordates as the clos...
متن کاملMolecular phylogeny and morphological homoplasy in fruitbats.
The present study evaluates the evolutionary framework of the Old World fruitbats based on the cytochrome b and 16S rRNA mitochondrial gene sequences from a wide range of taxa. Phylogenetic analyses indicated that morphology-based subfamilies and most suprageneric groups are nonnatural assemblages. They also support the existence of an endemic African clade of fruitbats. The discrepancy between...
متن کاملDeciphering Metazoan Phylogeny: The Need for Additional Molecular Data
SYNOPSIS. Our interpretation of the evolution of development, morphology, and diversity of multicellular animals hinges on a clear understanding of the phylogenetic relationships of metazoans. Currently, the field of metazoan phylogeny is in a state of flux, with new hypotheses of metazoan relationships emerging from analyses of 18S rDNA sequence data. Some of these analyses have been limited i...
متن کاملDeep molluscan phylogeny: synthesis of palaeontological and neontological data.
The position of the earliest-derived living molluscs, the Polyplacophora (chitons) and shell-less vermiform Aplacophora, remains highly contentious despite many morphological, developmental and molecular studies of extant organisms. These two groups are thought to represent either a basal molluscan grade or a clade (Aculifera) sister to the 'higher' molluscs (Conchifera). These incompatible hyp...
