N2  - The potential value of rapid sequencing of the srRNA molecule for phylogenetic reconstruction of the higher vertebrates was investigated. The study involved partial sequencing of 19 taxa that, along with 6 sequences from the literature, covered all of the major groups of higher vertebrates. The results show that sequencing of the srRNA molecule is not suitable at this taxonomic level because: (i) there is insufficient nucleotide sequence variation; (ii) expansion segments, although common, have a high probability of convergence for both their position and their sequence; and (iii) the phylogenetic branching of the higher vertebrates has been mainly 'bush-like' rather than 'tree-like'.
