==Key Stage 2==
===Meaning===
'''Grouping Classification of living things''' is done to make it easier to identify different creatures.
===About Grouping Living Things===
: Living things can be '''groupedclassified''' in different ways.: Scientists usually '''groupclassify''' things by common features or common behaviour.
===Examples===
====Vertebrates and Invertebrates====
: A [[vertebrate]] is an animal with a backbone.
: An [[invertebrate]] is an animal without a backbone.

Invertebrates:==Key Stage 4==Snail, Worm, Octopus, Insect, Arachnid===Meaning==='''Taxonomy''' is sorting living [[organism]]s into groups based on their similarities.
Vertebrates===About Taxonomy===Reptile: Before the discovery of [[DNA]] '''taxonomy''' was purely based on the appearance and behaviour of [[organism]]s.[[Carl Linnaeus]] developed a system of '''taxonomy''' based on the similar characteristics of [[organism]]s. [[Organism]]s were put into groups and sub-groups:*[[Kingdom]] - The largest group. Examples include [[animal]]s and [[plant]]s.*[[Phylum]] - The second largest group. Examples include [[chordata]] (animals with a backbone) and [[Arthropoda]] (animals with jointed legs and segmented bodies).*[[Class]] - Examples include [[mammal]]s (humans, neanderthals, chimpanzees, bonobos, Mammalgorillas, Birdbaboons, Fishlemurs, Amphibiandolphins, whales, cows, badgers) and [[bird]]s (crows, ostriches).*[[Order]] - Examples include [[primate]]s (humans, neanderthals, chimpanzees, bonobos, gorillas, baboons, lemurs) and [[cetacea]] (dolphins and whales).*[[Family]] - Examples include [[hominidae]] (humans, neanderthals, chimpanzees, bonobos and gorillas) and [[Cercopithecidae]] (baboons).*[[Genus]] - Examples include [[Homo]] ([[sapien]]s and [[neanderthal]]s) and [[Pan]] (chimpanzees and bonobos).*[[Species]] - Sapien is the name for our [[species]] of [[human]].Developments in [[genetic]]s have further added to this system with three [[Domain]]s above the [[Kingdom]]s:*[[Archaea]] - Primitive forms of [[bacteria]].*[[Bacteria]]*[[Eukaryota]] - All [[Eukaryotic Cell|eukaryotic]] [[organism]]s.: Analysis of [[DNA]] evidence has resulted in many changes to where [[organism]]s are placed in the '''taxonomy''' system. For example Panda's were once though to be closely related to the weasel but genetic evidence shows they are a type of bear moving them from the family; Mustelidae to the family; Ursidae.
