Document Summary
Taxonomy: science of naming & classifying organisms. Based on similarities in structure & function. Until invention came along that made classification a lot harder (microscope) Aristotle: classified organisms according to their habitat. Until 17th century people has agreed with aristotle"s idea. Universal naming system which is why we use latin. Linnaeus only has 2 major groups- vegetabilia & animalia. Classification changes & evolves as new evidence is discovered. Highest level of classification & organization for all living things (bacteria, archaea, eukaryotes) 400 identified but could be 4 million. Live in extreme environment- salt lakes, hot o2. Bacteria & archaea as domains & kingdoms. All families ends in (cid:498)idea(cid:499) for animals; (cid:498)aceae(cid:499) for plants. Family names are based on name of member in genus. Genus: group of species sharing major characteristic. Ability to reproduce w/one another & offspring can reproduce. When naming, don"t use whole taxonomic hierarchy, just genus & species. Ex: canis lupus ( genus / specie)
