Lesson+2+-+Taxonomy2

In biology, all living things can be classified using the following system, called the Linnaean Taxonomy. It is HIERARCHICAL, which means that organisms within the same category at any level have the same categories in all groups above that level.

For example, dogs and cats are of the same ORDER (carnivora) but not the same FAMILY (dogs are from the __Canidae__ family, whereas cats are from the__Felidae__ family). This means that dogs and cats are both from the same subgroups of Life, Domain, Kingdom, Phylum, Class and Order (all the levels above, and including, Order). They only differ in Family, Genus and, therefore, Species.

The following pdf file seeks to explain how this works by using a comparison of the Siberian Tiger and the Ring-tailed Lemur. It is a copy of the slideshow you will see (or have seen already!) in class.
