Reasons for Using a Classification System:

Clarification of speciesAllows for world-wide

research

How Linnaeus’System Works:

P h ylu m :Chordata

P h ylu m :Arthropoda

P h ylu m :Echinoderm ata

K in g d om :Anim alia

Kingdom:

The largest

and most

general taxon– Type of cells– Number of cells– Method of getting

food

Kingdom: Animalia

Eukaryote: well defined nucleus

Multicellular: more than one cell

Heterotroph: food from an outside source

Kingdoms are Divided into Phyla:

P h ylu m :Chordata

P h ylu m :Arthropoda

P h ylu m :Cnidaria

K in g d om :Anim alia

Phylum Chordata: Backbone

Paired appendages

Phyla are Divided into Classes:

C lassM am m alia

C lassAm phibia

P h ylu mChordata

Class: Mammalia Diaphragm

Families are Divided into Genera:

G en u sHom o

Cranial capacity increases with time.
