The Five Kingdom Classification System for Life - 638 Words

In 1758 a man called Carl Linnaeus proposed the two kingdom classification system. This system separated all living things into two categories called kingdoms. The two kingdoms were plante (plants) and animalia (animals).this system was the basis to our classification system today (the five kingdom system). In 1674 the first unicellular organisms were discovered by a man called Antoine van Leeuwenhoek. This discovery was due to his improvement to the microscope. This improvement meant an object could be magnified over 200 times, hence why micro-organisms were found. This improvement in the microscope also assisted into the discovery of prokaryotes and eukaryotes. This discovery meant that two new kingdoms could be created, kingdom monera and kingdom Protista. The improvement of the microscope has helped develop the two kingdom system into the five kingdom system it is today. DNA sequencing is a process used to determine the order of the nucleotides of a gene. Dna Sequencing has advanced extremely from almost a decade ago, due to the improvement of bioinformatics. Bioinformatics is the use of computer technologies to manage and analyse biological data. The improvement Bioinformatics has meant DNA sequencing has become much easier, faster and more cost effective. The improvement of the DNA sequencing technique meant that taxonomists could use DNA sequences as characteristics when classifying specimens. Using DNA sequences as characteristics meant classifying microorganismsShow MoreRelatedCompare and contrast the Five kingdom a797 Words   |  3 Pagesï » ¿Compare and contrast the Five kingdom and three domain classification system Classification is the method used by scientists to order living organisms. All species have a unique classification that results in a binomial name. classification is used to make it easier for different species to be identified by scientists.

Also, to show how Woese’s system of classification, was used to organize information about many types of organisms. So that you can define the organisms. This shows what the purpose is for the Systematics and Taxonomy Lab. Background information: Classification systems started around four century B.C by Aristotle (greek philosopher ).

It determines the methods of organizing diversity of life on earth. Therefore, classification helps in understanding millions of life forms in detail. Who started the classification of organisms? Let us explore the history of classification. History of classification One of theRead MorePhylogeny Is The Study Of Evolutionary Relationships1395 Words   |  6 Pagescladistics that connects ancestors to descendants is known as the tree of life. Charles Darwin completed the first known drawing of a tree of life in his book ‘Origin of Species’. Unrooted trees can be made, but these are not as useful as they simply connect descendants and do not plot a common ancestor. Phylogeny is linked to taxonomy – the hierarchical classification of organisms. The groups represented in the tree of life can sometimes match taxonomic groups, but often don’t. This is because ofRead MoreGalileo s Observation Of Astronomy1018 Words   |  5 PagesGalileo’s use of the telescope in 1609 revolutionized the field of astronomy because his observations disproved the geocentric theory and provided strong evidence for the Copernican/Heliocentric system. Galileo discovered four satellites orbiting Jupiter; this observation contradicted the geoc entric theory by proving that it is possible for objects to orbit something other than Earth. His observation of the phases of Venus supported the heliocentric theory because he discovered they were similarRead MoreThe Concept Of The Prokaryote Valid And Useful Or Fundamentally Flawed?1766 Words   |  8 PagesÉdouard Chatton in his 1925 paper ‘Pansporella perplex: Reflections on the Biology and Phylogeny of the Protozoa.’ (Chatton, 1925). Since then the term, when paired with its dichotomous counterpart ‘eukaryote’, has formed the fundamental basis for classification in biology. However in recent years the concept of the prokaryote has been wildly contested as being inaccurate (amongst other things), and the dichotomy of eukaryote/prokaryote based on a misleading and ultimately incorrect distinction that isRead MoreThe Oldest Sedimentary Rocks : Evidence For The Origin Of Life3774 Words   |  16 Pages1.

He developed a hierarchy, or in other words a ranking system for classifying organisms, that is the basis for modern taxonomy. LinnaeuÂ’s classification hierarchy included five levels: kingdom, class, order, genus, and species. Modern scientists have added two more classification levels to this, phylum and family. The current classification system divides all organisms into seven major Read MoreHonors Biology-Early Topics3382 Words   |  14 Pages (modified from Foundation Notes) Unit 1 Early Topics Main Sections * Definition of Biology * Characteristics of Life * Levels of Organization * SI Units and Relative Size * Scientific Method * Classification and Binomial Nomenclature Definition of Biology CHAPTER 1 Biology can be broadly defined as the â€Å"study of life† or the â€Å"study of living things†.
