Document Summary
We"ve been looking at divergence; today, we"ll face phylogeny and macroevolution. In july 1837, darwin began his notebook on the transmutation of species : p. 37, i think over his first evolutionary tree. He came up with this idea before anyone else because it was in a notebook he wrote setting precedent. In the origin , the only figure was a tree. What is the purpose of a biological classification: the name is a key to the literature on an organism. It has a predictive power: formal latin systematic naming to make universal, e. g. , oak trees. 2: enables interpretation of origins and evolutionary history. Taxon (pl. taxa) a named taxonomic unit at any level. Taxonomy the theory and practice of classification. Curators for many different organisms on earth (at museums) largely taxonomists who study the classification of their groups. Systematics the study of biodiversity and the evolutionary relationships among organisms. Schools of taxonomy (philosophical wars of the 70s & 80s)
