Molecularsystematics is a phrase that might be used to indicate that branch of the traditional field of systematics that utilizes data obtained by "molecular techniques".
Molecularsystematics is an essentially cladistic approach: it assumes that classification must correspond to phylogenetic descent, and that all valid taxa must be at least paraphyletic and preferably monophyletic.
Molecularsystematics often uses the molecular clock assumption that quantitative similarity of genotype is a sufficient measure of the recency of genetic divergence.
