Taxonomy The science of classification The science of classification Taxonomy is a system of grouping organisms based on phylogeny (evolutionary relationships), biochemistry and morphology (structure) Why classify? Why classify? –Huge amount of diversity among living things –Helps to make sense of it all

Goals of Classification Goal # 1: Give each type of organism a unique name understood by all Goal # 1: Give each type of organism a unique name understood by all Binomial nomenclature – 2-name naming system: Binomial nomenclature – 2-name naming system: –Developed by Carrolus Linneaus based on visible characteristics –Genus & species –Ex. Panulirus interruptus, a.k.a. Pacific spiny lobster, rock lobster or crayfish

Only about 1 million of 10 million organisms have been identified and named so far Only about 1 million of 10 million organisms have been identified and named so far

Goal # 2 – Group organisms according to how closely related they are Goal # 2 – Group organisms according to how closely related they are “Related” means they share a common evolutionary history (phylogeny) “Related” means they share a common evolutionary history (phylogeny) Allows scientists to develop better understanding about organisms & make comparisons & predictions Allows scientists to develop better understanding about organisms & make comparisons & predictions

Taxonomy How do we classify? How do we classify? –Look for common characteristics  Phylogeny (evolutionary relationships)  Biochemistry  Morphology (structure) –Ability to reproduce – biological species
