Incorporating molecular evolution into phylogenetic analysis, and a new compilation of conserved Polymerase Chain Reaction primers for animal mitochondrial DNA.

DNA data has been widely used in animal phylogenetic studies over the past 15 years. Here we review how these studies have used advances in knowledge of molecular evolutionary processes to create more realistic models of evolution, evaluate the information content of data, test phylogenetic hypotheses, attach time to phylogenies, and understand the relative usefulness of mitochondrial and nuclear genes. We also provide a new compilation of conserved polymerase chain reaction (PCR) primers for mitochondrial genes that complements our earlier compilation.
