Classification
Classification of biodiversity q. Define taxonomy q. Describe and use the binomial naming system, explain how this system was devised q. Explain why it is important to be able to classify newly discovered species using the binomial system q. State three domains of classification q. Identify and use the principle taxa: Kingdom, Phylum, Class, Order, Family, Genus, Species q. All groups with the same genus have a common evolutionary pathway (ancestral species) q. Explain why some organisms have been reclassified from their original taxonomic groups q. State that natural classifications allow scientist to predict the characteristics of an organism

Describe and use the binomial naming system, explain how this system was devised
Describe and use the binomial naming system, explain how this system was devised • The binomial naming system was first developed by Carolus Linnaeus (1707– 1778), in order to make species recognition easier. It identify organisms using the Genus and species name and should either be underlined or written in italics

Why is classification important
Why is classification important • It helps with the identification of organisms • It allows us to study relationships between organisms • It provides information about plants and animals from specific geographical locations • It allows us to study evolutionary ancestry

The three domains Archaea Bacteria (Eubacteria) Eukarya Originally considered as bacteria, however separated due having a different cell wall structure and differing metabolism Single celled prokaryote lacking in distinctive organelles A diverse range of prokaryotes that includes extremophiles Example Aeropyrum pernix Example E coli Cells with chromosomes surrounded by a nuclear membrane and possessing distinctive organelles

Common origins Organisms are classified according to their similarities and therefore organisms in the same genus must have a similar evolutionary pathway
We get it wrong sometimes • With the increased use of DNA profiling we can now classify organisms on a cellular level. Due to this we have discovered that scientists have misclassified several organisms

Predicting behaviour • Once we have classified an organism we can then use it to predict the characteristics of another organism from the same genus. • For example we can predict the behavior of an extinct organism by studying the behavior and characteristics of a closely related organism.
