different between systematics vs phenetics

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.

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.

   • 1992, Alec L. Panchen, Classification, Evolution, and the Nature of Biology, page 132,

     We have seen in Chapter 6 and the previous chapters that dissatisfaction with traditional taxonomy gave rise, after the Second World War, to two distinct attempts at a remedy - phenetics and cladistics.

   • 2000, F.G. Priest, Michael Goodfellow, Preface, Applied Microbial Systematics, page xi,

     Microbial systematics has enjoyed two major advances in the latter half of this century: the introductions of numerical phenetics and molecular techniques for direct comparisons of organismal genomes. Numerical phenetics (taxonomy) was very influential during the 1960s and 70s in providing the first objective approach to bacterial classification.

   • 2001, Jody Hey, Genes, Categories, and Species: The Evolutionary and Cognitive Cause of the Species Problem, page 147,

     One of the most famous and fully developed arguments along these lines, was a justification for phenetics, a school of systematic thought that proposed mathematical methods for grouping organisms based on measurements of similarity {Sokal and Sneath 1963).
