1. THE CLASSIFICATION OF LIVING THINGS

2. Classification Classifying living organisms is called – taxonomy
Founded by Carolus Linnaeus (1700 s)
Species were grouped based on physical characteristics

3. Naming Organisms
Each organism is given a two - word name – Binomial Nomenclature
The first word – genus; the second word – species
Human groups: they all belong to the same genus Homo sapiens, Homo erectus, Homo habilis, Homo neanderthal

4. The Classification of Living Things
Homo erectus
Homo habilis
Homo neanderthal H

5. The Classification of Living Things
Dog like groups: the same genus, different species
Canis familiaris - dog
Canis lupus – coyote
Canis latrans - wolf

6. The Classification of Living Things
Hierarchy of Groups
Each kingdom is divided many times into smaller and smaller groups (taxa,taxon – singular)
Species is the most specific taxon – to be included in the same species organisms must be able to interbreed and produce fertile off springs

8. The Classification of Living Things
7 levels of similarities (7 Taxa): from the least specific to the most similar
Kingdom (the least similar taxon)
Phylum
Class
Order
Family
Genus
Species (the most specific, similar taxon)

9. The Classification of Living Things
Wolf Panther
Share the same taxa: kingdom, phylum, class, and order
Belong to the different taxa: family, genus and species
