ARISTOTLE, LINNEAUS, BINOMIAL NOMENCLATURE

Aristotle

• Greek Philosopher
• Developed first widely accepted system of classification
• Classified all organisms into 2 groups (Plants and Animals)
• Subdivided plants into herbs, shrubs, trees
• Subdivided animals into groups by characteristics

ARISTOTLE'S FLAW

• DIDN'T GROUP ORGANISMS ACCORDING TO EVOLUTIONARY HISTORY.

Carl Linnaeus

• Swedish botanist
• Developed method of grouping organisms that is still used today
• Based on structural and physical similarities of organisms

BINOMIAL NOMENCLATURE

• Two word naming system
• First word: Genus
• Second Word: Species

GENUS

• Consists of a group of similar species

SPECIES

• Describes a characteristic of the organism
• Members of the same species reproduce and make viable offspring

EXAMPLE:

• Modern Humans
• Homo sapiens (should be italicizes)
• Humans are in the genus Homo
• Characteristic of humans is Wisdom
• Latin word for Sapiens

Latin is the language of scientific names. Taxonomists use latin because it is no longer spoken and therefore doesn't change.

FORMAT

• When written Underline
• When typed italicize
• Genus capitalized
• Species lowers
