Phylogenetic Relationship , Divergence Times , and Rates of Molecular Evolution for Camarodont Sea Urchins ’


The phylogenetic relationships of 21 relatively common and well-studied genera of camarodont echinoids were established using a numerical cladistic approach. This combines data about test morphology, pedicellarial structure, tooth ultrastructure, and larval morphology. The fossil record of the group was reappraised in the light of this analysis, and times… (More)
