1Classifying Organisms Easier to Study!ClassificationThe process of grouping thing based on similarities.TaxonomyThe scientific study of how living things are classified
2Naming Systems Aristotle Carolus Linnaeus 1707-1778 Carolus Linnaeus (Carl von Linné)Naming SystemsCarolus Linnaeus“Father of Taxonomy”Gave us system we use nowBinomial Nomenclaturetwo namesAristotle5AD---1st to ClassifyPlants VS Animalsherbs-shrubs-trees land-air-sea
3Binomial Nomenclature 2 NamesGenus andSpeciesScientific NameWritten in italics. First word is capitalizedand the second is not. Homo sapiensIf handwriting the scientific name: Underline to show italics.
4Genus Species Classification grouping that contains similar, closely related organismsSpeciesGroup of similar organismsthat can mate with eachother and produce offspringthat can also mate andReproduce.
5Most biologists classify organisms into 8 levels. Broad to Specific More levels share more have in common
