Phylogeny and classification of the Digenea (Platyhelminthes: Trematoda).
- P. D. Olson, T. Cribb, V. Tkach, R. Bray, D. Littlewood
- Biology, Medicine
- International journal for parasitology
- 1 July 2003
Complete small subunit ribosomal RNA gene (ssrDNA) and partial (D1-D3) large subunit ribosomal RNA gene (lsrDNA) sequences were used to estimate the phylogeny of the Digenea via maximum parsimony and… Expand
Acoel flatworms: earliest extant bilaterian Metazoans, not members of Platyhelminthes.
- I. Ruiz-Trillo, M. Riutort, D. Littlewood, E. Herniou, J. Baguñá
- Biology, Medicine
- Science
- 19 March 1999
Because of their simple organization the Acoela have been considered to be either primitive bilaterians or descendants of coelomates through secondary loss of derived features. Sequence data of 18S… Expand
Interrelationships and evolution of the tapeworms (Platyhelminthes: Cestoda).
- P. D. Olson, D. Littlewood, R. Bray, J. Mariaux
- Biology, Medicine
- Molecular phylogenetics and evolution
- 1 June 2001
Interrelationships of the tapeworms (Platyhelminthes: Cestoda) were examined by use of small (SSU) and large (LSU) subunit ribosomal DNA sequences and morphological characters. Fifty new complete SSU… Expand
The interrelationships of all major groups of Platyhelminthes: phylogenetic evidence from morphology and molecules
- D. Littlewood, D. Littlewood, K. Rohde, K. A. Clough
- Biology
- 1999
We used a data matrix of 65 morphological characters from 25 ingroup and 6 outgroup taxa, and an alignment comprising complete 18S rDNA sequences from 82 species of parasitic and free-living… Expand
The interrelationships of proseriata (Platyhelminthes: seriata) tested with molecules and morphology.
- D. Littlewood, M. Curini-Galletti, E. Herniou
- Biology, Medicine
- Molecular phylogenetics and evolution
- 1 September 2000
Proseriate flatworms are common members of the interstitial benthic fauna worldwide, predominantly occupying marine environments. As minute animals, having relatively few characters useful for… Expand
Phylogeny of the Platyhelminthes and the evolution of parasitism
- D. Littlewood, D. Littlewood, K. Rohde, R. A. Bray, E. Herniou
- Biology
- 1 September 1999
Robust phylogenies provide the basis for interpreting biological variation in the light of evolution. Homologous features provide phylogenetically informative characters whereas homoplasious… Expand
Phylogenies inferred from mitochondrial gene orders-a cautionary tale from the parasitic flatworms.

- Molecular biology and evolution
- 1 July 2000
[Extract] Mitochondrial genomes have been used in numerous studies to investigate phylogenetic relationships among eukaryotes at many levels (e.g., Smith et al. 1993; Boore et al. 1995; Boore,… Expand
Testing the molecular clock: molecular and paleontological estimates of divergence times in the Echinoidea (Echinodermata).

- Medicine, Biology
- Molecular biology and evolution
- 1 October 2006
The phylogenetic relationships of 46 echinoids, with representatives from 13 of the 14 ordinal-level clades and about 70% of extant families commonly recognized, have been established from 3 genes… Expand
The complete mitochondrial genomes of Schistosoma haematobium and Schistosoma spindale and the evolutionary history of mitochondrial genome changes among parasitic flatworms.
