Classification Alpha Taxonomy

Taxonomy Each organism has a name: Specie name –Each species is assigned two names: binomial nomenclature –First part of name is the genus –Second part of name is the specific epithet that when combined with the first part denotes a species. –Homo sapiens

Carolus Linnaeus ( ) Swedish botanist Developed method of grouping organisms based on similar characteristics. Better system than Aristotle’s land, air, water system.

Taxonomy cont. Hierarchy in classification –Each species is grouped into progressively broader categories. –Seven major categories: Kingdom Phyla Class Order Family Genus Species

Binomial Nomenclature Two part name Homo sapiens “wise man” Bubo virginianus (great horned owl) owlgirl

What’s in a name? Latin or Greek description: the names describe the organism. What do you think these names mean? Matris accipiter Metus convincere Try some on your own….

Taxonomic Criteria Must include specific internal, external, environmental, developmental, biochemical and behavioral characteristics. Combined knowledge of: –Comparative anatomy –Comparative embryology –Molecular biology
