The first rank in the classification system is called a kingdom. Every different species has a unique species identifier and the more closely a species is related to it on the evolutionary tree of life, it will be included in a more inclusive group with the species being classified.

Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together.

The taxonomic classification system (also called the Linnaean system after its inventor, Carl Linnaeus, a Swedish botanist, zoologist, and physician) uses a hierarchical model. Modern scientific classification is based on structure and functions. The classification system used today is that of Whittaker (1959, modified by Margulis), and contains five kingdoms: prokaryotae, protoctista, fungi, plantae and animalia. Moving from the point of origin, the groups become more specific, until one branch ends as a single species. This is usually the kingdom where organisms which aren’t animals, plants or fungi go. This is a PowerPoint presentation for Topic 3 in the Edexcel Biology B A Level course that starts in 2015. The vast numbers of living forms must be named and arranged in an orderly manner so that biologists all over the world can be sure they know the exact organism that is being examined and discussed. The classification system used today is that of Whittaker orders into classes, classes into phyla (singular phylum), and Three Domain System of Classification. different phylogenies (e.g. As we go through the larval development, and gene sequences. Most of us are accustomed to the Linnaean system of classification that assigns every organism a kingdom, phylum, class, order, family, genus, and species, which, among other possibilities, has the handy mnemonic K ing P hilip C ame O ver F or G ood S oup.
