  • n. The science of systematic classification, especially of organisms. Depending on context this may be the same as taxonomy or distinct. In the latter case systematics will be taken to mean the research into the relationships of organisms, while taxonomy will involve itself in the recognition and the naming of taxa.

from The Century Dictionary and Cyclopedia

  • n. The principles and practice of classification; the study of system, or the formation of any system; systematology; taxonomy. See system, 11.

  • Cladistics, or phylogenetic systematics, is a system of classifying living and extinct organisms based on evolutionary ancestry as determined by grouping taxa according to "derived characters," that is characteristics or features shared uniquely by the taxa and their common ancestor.

    A Disclaimer for Behe?

  • If dinosaurs really do get lumped more than they already are, it strikes me that the trend within dinosaur systematics is in direct opposition to that occurring among extant tetrapods.

  • Snail shells are important for use in systematics, that is deciding who is more closely related to whom.

  • The science of figuring out these trees, known as systematics, has progressed significantly in the last two decades largely due to advances in computation, genetics and molecular biology.

  • Oh, I've also slowly been making my way through the new (September) issue of the Journal of Vertebrate Paleontology, and have read, over the past few days, "A new ornithischian dinosaur from the Lower Cretaceous Kuwajima Formation of Japan," "The anatomy and systematics of Colepiocephale lambei [Dinosauria: Pachychephalosauridae]," and "Rapid somatic expansion causes the brain to lag behind: the case of the brain and behavior of New Zealand's Haast's Eagle [Harpagornis moorei]."

  • Cladistics (ancient Greek: κλάδος, klados, "branch") is a form of biological systematics that classifies species of organisms into hierarchical monophyletic groups.

    About 'What Darwin Got Wrong'

  • Common traits and shared genetics are tools that help biologists build the clade systematics.

    About 'What Darwin Got Wrong'

  • In biological systematics, a clade (from ancient Greek κλάδος, klados, "branch") signifies a single "branch" on the "Tree of life", a group composed of a single ancestor and all its descendants.

  • Systematics is the study of the diversity of organism characteristics. In biology, systematists are the scientists who classify species and other taxa, which they do with the aim of defining how they relate evolutionarily.
