Systematic Biology

Aims & Scope

Systematic Biology is the bimonthly journal of the Society of Systematic Biologists.

Papers for the journal are original contributions to the theory, principles, and methods of systematics as well as phylogeny, evolution, morphology, biogeography, paleontology, genetics, and the classification of all living things.

A Points of View section offers a forum for discussion, while book reviews and announcements of general interest are also featured.
