Taxonomy is the science of classifying living things. A group of organism at a particular level in a classification system is called a taxon.

The binomial classification system removes ambiguity from common name: Flathead - goujon caille - opelousas cat - yellow cat – spotted cat Crappie - sac-au-lait - white perch – strawberry bass – paper mouth – calico bass Each organism has a binomial name made up of the genus the organism is in and the particular species name: Genus species.

Most recent common ancestor and all descendants Most recent common ancestor but not all descendants (think – just dinosaurs) Does not include most recent common ancestor of all the members Common ancestor to all groups here. Evolutionary tree = a phylogeny

Clade – a group of organisms related by descent; this approach to constructing a phylogeny is called cladistics. By separating groups of organisms based on specific traits, a cladogram can be constructed. How is it decided which trait to use?

Three domains are now recognized (may be subject to change):

Domain: Archaea – Archaebacteria: inhabit diverse, usually extreme habitats Bacteria – eubacteria; ‘There are more living eubacteria in your mouth than there are mammals living on Earth’! Eukarya – eukaryotes; four kingdoms: Animalia, Plantae, Fungi, Protista
