| − | ===Meaning===
| |
| − | '''Classification''' is sorting living [[organism]]s into groups based on their similarities.
| |
| − | | |
| − | ===About Classification===
| |
| − | : Before the discovery of [[DNA]] '''classification''' was purely based on the appearance and behaviour of [[organism]]s.
| |
| − | [[Carl Linnaeus]] developed a system of '''classification''' 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, 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, bonobos and gorillas) and [[Cercopithecidae]] (baboons).
| |
| − | *Genus - Examples include [[Homo]] ([[human]]s and [[neanderthal]]s) and [[Pan]] (chimpanzees and bonobos).
| |
| − | *Species - Sapien is the name for the [[human]] [[species]].
| |
| − | Developments in [[genetic]]s have further added to this system with three [[Domain]]s above the [[Kingdom]]s:
| |
| − | *Archae - Primitive forms of [[bacteria]].
| |
| − | *Bacteria
| |
| − | *Eukaryota - All [[Eukaryotic Cell|eukaryotic]] [[organism]]s.
