Taxon sampling and the phylogenetic position of Passeriformes: evidence from 916 avian cytochrome b sequences.
Attempts to resolve relationships among major groups of birds from DNA sequences have been plagued by the problem of apparent long branches connected by short internodes (Sibley and Ahlquist, 1990) and the difculties of sampling a large number of taxa in one study. A recent study of relationships among major avian lineages based on complete mitochondrial DNA sequences (Mindell et al., 1997, 19...
متن کاملPhylogenetic relationships of the thylacine (Mammalia: Thylacinidae) among dasyuroid marsupials: evidence from cytochrome b DNA sequences.
DNA sequences from the mitochondrial cytochrome b gene were obtained from a museum specimen of the presumed extinct thylacine (Thylacinus cynocephalus) and were compared with homologous sequences from 13 representatives of the Australian marsupial family Dasyuridae. The relationship of the thylacine to dasyurids has been suggested by previous anatomical and molecular studies, but its position w...

متن کاملIncreased taxon sampling greatly reduces phylogenetic error.
Several authors have argued recently that extensive taxon sampling has a positive and important effect on the accuracy of phylogenetic estimates. However, other authors have argued that there is little benefit of extensive taxon sampling, and so phylogenetic problems can or should be reduced to a few exemplar taxa as a means of reducing the computational complexity of the phylogenetic analysis....
متن کاملTaxon sampling and the accuracy of phylogenetic analyses
Appropriate and extensive taxon sampling is one of the most important determinants of accurate phylogenetic estimation. In addition, accuracy of inferences about evolutionary processes obtained from phylogenetic analyses is improved significantly by thorough taxon sampling efforts. Many recent efforts to improve phylogenetic estimates have focused instead on increasing sequence length or the nu...
