A Cautionary Note on Linear Measurements and Their Ratios in Taxonomy

Autor: Antonio G. Valdecasas

Publikováno v: Taxonomy, Vol 3, Iss 1, Pp 1-9 (2022)

Statisticians work with figures, whereas scientists work with estimated quantities. Every direct (physical) measurement has some degree of uncertainty. Single numbers pose no problems, and an implied range can always be specified. Difficulties arise

The systematics of many groups of organisms has been based on the adult stage. Morphological transformations that occur during development from the embryonic to the adult stage make it difficult (or impossible) to identify a juvenile (larval) stage i
