1. Classification

2. Taxonomy and Evolution
Taxonomy – (a branch of Biology) involves the
identification, naming, and
classification of species
One goal of taxonomy is to assign a universal scientific name to each known species

3. Binomial Nomenclature
Each species is assigned a two part scientific name
Scientific names are written in italic
First word begins with a capital letter
Genus
Second word is lowercase
Species
Ex: Homo sapian

4. The Linnaean System of Classification
K: King
P: Phillip
C: Came
O: Over
F: For
G: Good
S: Spaghetti

6. Modern Evolutionary Classification
Phylogeny – the evolutionary history of lineages
is to group species into larger categories that reflect lines of evolutionary descent, rather than overall similarities and differences

7. Phylogenetic Trees
The pattern of branches can tell you how closely related species are
The farther the “split”
the further “away” the
two species are from
each other
The closer the “split”
the more related

8. Cladistics Method mostly used today
Derived Characters – unique features that unite the
organisms as a clade (group)
Cladogram – links groups of organisms by showing how
evolutionary lines, or lineages, branched off
from common ancestors.

9. Six Kingdom Scheme
Eubacteria
Archaebacteria
Protist
Fungi
Plantae
Animalia
