Classification

3 Domains
Archaea, bacteria, eukarya (protists, plants, animals, fungi)
6 Kingdoms
Bacteria, archaea, plants, animals, fungi, protists

Taxonomy
Created by Carolus Linnaeus
Classified using morphology of organisms
All species given a Latin scientific name

Hierarchy of Groups
Organisms that look alike are placed in groups called taxon
Kingdom > Phylum > Class > order > family > genus > species
King Phillips Crossed Oceans For Great Sex
As you move down the system, each taxon contains fewer species
Binomial nomenclature: (genus name, species name)

Dichotomous key- identify organisms using their morphology (linear path)
Common ancestry- different species evolved form one common ancestor (the more recent the ancestor, the fewer the differences in DNA)
Phylogeny- studying the evolutionary relationships between/among species
Phylogenetic analysis- compare current living species with extinct species
Phylogenetic tree- branching diagram representing a hypothesis for evolutionary relationships between organisms (common
