'''Grouping Classification of living things''' is done to make it easier to identify different creatures.

: Living things can be grouped '''classified''' in different ways.: Scientists usually group '''classify''' things by common features or common behaviour.

====Vertebratesand Invertebrates====Reptile: A [[vertebrate]] is an animal with a backbone.: An [[invertebrate]] is an animal without a backbone. {| class="wikitable"|+ All of these animals have a backbone so they examples of vertebrates.|[[File:Newt.png|center|200px]]|[[File:Puffin.png|center|200px]]|[[File:Trout.png|center|200px]]|[[File:Fox.png|center|200px]]|[[File:Adder.png|center|200px]]|-| style="height:20px; width:200px; text-align:center;" |Amphibians are vertebrates.| style="height:20px; width:200px; text-align:center;" |Birds are vertebrates.| style="height:20px; width:200px; text-align:center;" |Fish are vertebrates.| style="height:20px; width:200px; text-align:center;" |Mammals are vertebrates.| style="height:20px; width:200px; text-align:center;" |Reptiles are vertebrates.|} {| class="wikitable"|+ None of these animals have a backbone so they are examples of invertebrates.|[[File:Snail.png|center|200px]]|[[File:Earthworm.png|center|200px]]|[[File:Scorpion.png|center|200px]]|[[File:Octopus.png|center|200px]]|[[File:Fly.png|center|200px]]|-| style="height:20px; width:200px; text-align:center;" |Snails are invertebrates.| style="height:20px; width:200px; text-align:center;" |Earthworms are invertebrates.| style="height:20px; width:200px; text-align:center;" |Scorpions are invertebrates.| style="height:20px; width:200px; text-align:center;" |Octopuses are invertebrates.| style="height:20px; width:200px; text-align:center;" |Flies are invertebrates.|} ====Flowering Plants and other Plants====: [[Flowering Plants]] are [[plant]]s that grow [[Flower|flowers]].: Not all [[Plant|plants]] grow [[Flower|flowers]]. There are also [[Moss|Mosses]], Mammal[[Fern|Ferns]] and [[Conifer|Conifers]] which don't grow flowers. {| class="wikitable"|+ There are 4 main groups of plants.|[[File:AppleTreeBlossom.png|center|200px]]|[[File:Conifer.png|center|200px]]|[[File:Moss.png|center|200px]]|[[File:Fern.png|center|200px]]|-| style="height:20px; width:200px; text-align:center;" |[[Flowering Plants]].| style="height:20px; width:200px; text-align:center;" |[[Conifer|Coniferous Plants]].| style="height:20px; width:200px; text-align:center;" |[[Moss|Mosses]]| style="height:20px; width:200px; text-align:center;" |[[Fern|Ferns]]|} ==Key Stage 4=====Meaning==='''Taxonomy''' is sorting living [[organism]]s into groups based on their similarities. ===About Taxonomy===: 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, Birdneanderthals, Fishchimpanzees, bonobos, gorillas, baboons, lemurs, dolphins, 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, Amphibianbonobos 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.
