Classification and Taxonomy



Classification and Taxonomy

Taxonomy—the branch of science that names organisms and

studies how they are related.

The first classification system was developed by Aristotle.

Aristotle’s: Plants Animals

System Herbs, shrubs, trees land, air, water

The modern system was developed by Carolus Linnaeus. It is based on relationships between organisms, not where they live.

Binomial nomenclature—the two-part naming system used to

identify organisms.

Scientific name—the unique two part Latin name of an organism.

A scientific name consists of genus and species.

The correct way to write a scientific name is Canis familiaris.

If hand-written the names must be underlined: Canis lupus.

What does a scientific name show? If a person’s name were written last name first, it would show the same relationship as a scientific name. Organisms with the same genus name are closely related, but each has a different species name.

There are 7 levels of classification of organisms.

They can be remembered in order by:

King Philip Came Over For Good Spaghetti

The more levels of classification organisms have in common, the more closely related they are.
