The Tree of Life
Originally Everything was a plant or an animal
Discovery of Cells and Bacteria In the mid 1600s using newly invented microscopes Changed view of life dramatically
Taxonomy Existed Before Evolution Was Understood Simply classified things to make sense of the world Modern taxonomy credited to Carolus Linnaeus in the 1700s
Evolution and Taxonomy Evolution obviously explains why species seem related and can be classified together Modern goal of taxonomy is to construct the tree of life based on relationships
5 Kingdom System Originally there were 5 kingdoms Monera /Bacteria Protista Fungi Plantae Animalia
2 Empires Prokaryotes and eukaryotes
3 domain system
The Tree is REALLY Complicated… (Chloroplasts)
A Note about DKPCOFGS A gross oversimplification- there are many more branches Still used, but somewhat outdated Lots of sub-phyla, super-families etc.
Example Class Reptilia Class Aves Lizards/ Snakes Turtles
