Document Summary

In this lecture topic: how has the living world been grouped in the past, what didn"t work when classifying, cladistics; demonstrates what is there, cladogram for the whole world. Must all be related to one another. Share common ancestor: hierarchical, linnaeus, nested structure (nesting) Must be related to evolutionary as well. Puts in evolutionary accurate historical context: system needs to accommodate all the various changes; flexibility, any characteristic; make evolutionary tree, originally done on morphology, then embryology then molecularly, arrange biodiversity in a predictable pattern that is flexible. Definition (continued: dichotomous; darwin, based on yes or no questions, one event -> two events -> four events, build dichotomous branching pattern that info stored and was flexible. Types of taxonomies: folk, animate, inanimate, simple, naturally; speaking world, verbal taxonomy; passed through generations. Someone was the keeper of the word : human mind. Can keep track of 500 to 600 things that are nested 4 or 5 tiers deep.
