Classification

The purpose of classification is to
systematically catalog organisms in ways
that show their relationship to one another.

Systematics is the study of the diversity of
organisms and how they are related.

Taxonomy is the science of identifying,
classifying and naming organisms.


This is the diversification of a species into different
lines as they adapt to new ecological niches and
ultimately evolves into distinct species.

 *Natural selection is the principle mechanism
driving evolution.

Over 200 years ago, Swedish botanist
Carolus Linnaeus invented a way of naming
organisms – the system of binomial
nomenclature.

This two-part name consists of the genus
and specific epithet (when added to the
genus it becomes species).

The genus (always capitalized) is a group
of very similar organisms related by
common descendants and sharing similar
traits.

The specific epithet (always lower case) is a
unique group within a genus who share the
same traits and can successfully reproduce
only with members of the same species.

The scientific name is always underlined if
written or italicized if typed.

SN are always in Latin in order to be
universal. The Latin names are usually
descriptive:
– habitat (water tupelo – Nyssa aquatica)
– physical traits (red maple - Acer rubra)
– geographic location (gray squirrel - Sciurus
carolinensis)
– use (sugar maple - Acer saccharum)
– in commemoration (desert cottontail - Sylvilagus
auduboni)
