Introduction
Study of organic diversity
Biodiversity
1.70 million of earth’s estimated 10 – 100 million species have been scientifically erected – named and classified
Marine biota – 3,40,000 species
Systematic zoology – discovers names – determine relationship – studies evolution of organisms

Systematics
Taxonomy – Greek words – taxis arrangement – Nomos – Law
Candolle 1813 – Theory & practice of classifying organisms
Classification – identification
Ordering of animals
Species placed by deductive procedure to each taxa
Alpha taxonomy – description of new taxonomy
Beta taxonomy – worked out species level and higher categories
Gamma taxonomy – Intraspecific variations and its evolutionary relationship – casual interpretation of organic diversity
