Taxonomy is the study of the classification of organisms, it is the organization (separation) of all the known organisms into groups based on their shared features, these groups are then organized into further, larger groups. These groups are all referred to as Taxa (Taxon - singular). The taxa used in taxonomy are: Species, Genus, Family, Order, Class, Phylum and kingdom, each group getting larger going form species to kingdom. Taxa Used in Taxonomy ===================== Species ------- Organisms That are able to interbreed, producing fertile offspring are considered to be of the same species, this taxon can also be divided into subspecies and then strains (to give more…show more content…
The first name is always a noun and the second an adjective. The relation between Phylogeny and Classification Phylogeny is the evolutionary history of a species, it is a valuable biological mechanism used to determine what genus a species may fall into, as species which have very similar (homologous) features can be assumed to have evolved from the same common ancestors, e.g. horses donkeys and zebras all have homologous features and can all be filed under the genus Equus. Artificial selection Humans have also had a hand in how many of the animals we see every day are the way they are. Take Dogs for example, they have been bred to produce a wide variety of qualities that we find desirable in them, and these can be behavioural, or physical properties. Guard dogs have been bred to have phenotypes such as broad shoulders, heavy build and they also have been selectively bred to be aggressive and territorial other dogs, such as terriers have been bred to be small and fairly docile, ideal qualities for a house pet. In this case Humans have taken the place of natural selection for the dogs, to tailor them to our requirements. Desirable phenotypes which are recognized in the
