different between systematics vs cladistics

systematics

English

Noun

systematics (uncountable)

  1. The study of classification systems and nomenclature.
  2. The systematic classification of a branch of science, especially the classification of organisms.
  3. A branch of Christian theology that formulates an orderly, rational, and coherent account of Christian beliefs. It comprises dogmatics, ethics and philosophy of religion.
  4. The place where legal provisions stand as relevant for their interpretation.

Usage notes

Depending on context, when used to mean the classification of biological organisms, this may be the same as taxonomy or distinct. When distinct, systematics can mean the research into the relationships of organisms (phylogenetics), while taxonomy involves itself in the recognition and the naming of taxa. Alternatively, Systematics can mean the broader category that includes both phylogenetics and taxonomy.

      Here we suggest emphasis on the techniques of cladistics (Eldredge and Cracraft 1980; Wiley 1981; Coddington 1988) because they provide a clear means of organizing phylogenetic information in branching diagrams.
    • 2001, Clare Bates Congdon, Gaphyl: A Genetic Algorithms Approach to Cladistics, Luc de Raedt, Arno Siebes (editors), Principles of Data Mining and Knowledge Discovery: 5th European Conference PKDD 2001, Volume 5, Springer, LNAI 2168, page 67,
      This research investigates the use of genetic algorithms to solve problems from cladistics — a technique used by biologists to hypothesize the relationships between organisms.
