Why classify?
•Humans have developed classification systems in order to make sense of the
abundant biological diversity that exists in nature.

Taxonomy
•…the identification, naming, and classification of species
•Taxonomists spend their time searching for previously unknown organisms, determining their relationships to known organisms, and giving them names

Eight Levels of Taxonomic
Classification
• Domain
• Kingdom
• Phylum
• Class
• Order
• Family
• Genus
• Species

From biggest to smallest:
1.Domain – compare to a continent 2. Kingdom – compare to a country3. Phylum –compare to a state4. Class – compare to a county5. Order – compare to a town6. Family - compare to a neighborhood7. Genus - compare to a street8. Species – compare to house number

Writing Scientific Names
•The rules for writing scientific names:
• -CAPITALIZE the first letter of the genus name.• -the species name is all lower case letters.• -Both names must be underlined or italicized.
•Example: human = Homo sapiens

Another Example
• E. coli --Sometimes the genus name is abbreviated.
• Escherichia coli

Modern System of Classification
• Domain Archae: unicellular (one cell) prokaryotes (contain no nuclei),
harsh environments.
• Domain Bacteria: common form of bacteria, circular shaped, most are aerobic (needs oxygen).
Domain Eukarya:
• Protista: eukaryotesm(have nuclei) mostly unicelluar, no complex tissues or systems.

• Fungi: heterotrophic (cannot make its own food) eukaryotes, unicellular and multicellular(2 or more cells), absorb nutrients, 100,000 species.
• Plantae: Eukaryotes, multi-cellular, most are autotrophic (make their own food) ------ photosynthesis, 350,000 species.
• Animalia: Eukaryotes, multi-cellular,
Heterotrophic (cannot make its own food), most have symmetrical bodies.
