Slow mitochondrial COI sequence evolution at the base of the metazoan tree and its implications for DNA barcoding.

Journal of molecular evolution - 1 Feb 2008

Huang Danwei, Meier Rudolf, Todd Peter A, Chou Loke Ming

Abstract excerpt

The evolution rates of mtDNA in early metazoans hold important implications for DNA barcoding. Here, we present a comprehensive analysis of intra- and interspecific COI variabilities in Porifera and Cnidaria (separately as Anthozoa, Hydrozoa, and Scyphozoa) using a data set of 619 sequences from 224 species. We found variation within and between species to be much lower in Porifera and Anthozoa compared to...
