Taxonomy (Science Skills) Science Skills Class Code SC20210
What is Taxonomy? Taxonomy – naming organisms based on common traits Scientists name large groups of animals, smaller groups, all the way down to individual species. The system they use to name animals is this: Domain Kingdom Larger groups PhylumTaxonomic Groups Class Order Order Family Family Genus Species Species

Species Scientific NamesSpecies names are always binomials, which means there are 2 names,example:Carcharodon carcharias is the scientific name for a great white shark.Scientific names are derived from Latin.Kingdom, phylum, class, order, family, genus are NOT binomials.Carcharodon carcharias
Taxonomy and Trees Organisms are named based on their position on evolutionary trees.KingdomPhylumClassOrderFamilyGenusSpecies
How Trees are ConstructedToday, most trees are constructed using DNA. Single basepair differences in the DNA are traits.Extinct species are put onto the trees using traits from theorganism’s fossils.
Scientific vs Common Names Animals have scientific and common names. Common names – example: “catfish” But there are about 3000 species of catfish!! So which one?? Scientific names – example: Lacantunia enigmatica Lacantunia enigmatica is ONE species of catfish, so scientists from different countries can talk about it without any confusion. Scientific names are more clear and lead to less confusion Good bad examplesCommon name Easy to remember Some species can Large forest gecko have many Catfish common namesScientific name -One species will have Hard to Gekko smithii only one scientific name. remember and Lacantunia enigmatica -Clear for people who pronounce speak different languages.
