Classification

Scientists of all nationalities have agreed to use Scientific names for species. Scientific names use the binomial system (Genus species) There is a hierarchy of taxa from domain to species. A classification group (normally) contains all the species that have evolved from a common ancester. Classification Helps to identify species and Helps identify characteristics shared by all species within a group.

The hierarchy of taxa There are three Domains Eukaryote Eubacteria Archaea Mnemonic Classification group (Taxonomic group) King Kingdom Penguins Phylum Congregate Class On Order Frozen Family Ground Genus Sometimes Species

Sometimes new evidence causes scientists to move a species from one group into another. I grouped plants according to how many anthers they had. This has completely changed. Scientists still use my system of binomial nomenclature. Every species has a latinised name composed of: it’s Genus (with a capital letter) and its species (without a capital letter) Carl von Linné - (1707–1778), a Swedish botanist, invented the modern system of binomial nomenclature. Biologists have given him a Latin name = Carolus Linnaeus
