Bio 11: Thurs Sept 6 - Taxonomy

Today we corrected the Science Words from last day, read pgs. 20 - 22, 28 - 29 in the textbook, attempted to classify a bunch of different animal samples, and then took some notes on Taxonomy (we'll finish them tomorrow):

·      The science of classifying organisms is known as taxonomy.
·      Carl Linnaeus (a.k.a. Carl von Linne´) 1707 – 1778 in Sweden proposed a method to classify all living things world wide for better scientific communication.
o   Organisms were classified based on similarities in structure or “body plan.”
o   Nowadays, DNA and other biochemical analyses are used to help, but they sometimes conflict with body similarities.
o   All organisms were put into 5 major “kingdoms.”
o   Each kingdom is further divided into further levels of classification, and in 1990 a category before kingdom was added: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
(Dorky kids play catch over farmer green’s shed)
o   There are 3 domains: Archaea (ancient bacteria) and Bacteria and Eukarya. Archaea and Bacteria are prokaryotic (no membrane enclosed organelles in cells) and used to be one kingdom: Monera, and Eukarya are Eukaryotic (membrane enclosed organelles in cells) with the remaining 4 kingdoms: protista, fungi, plantae, and animalia.
