Evolutionary theory postulates that organisms on earth are related by common ancestry, which inevitably results in species with common characteristics. The evolutionary history of a group of organisms is known as a phylogeny and can be illustrated in the form of a phylogenetic tree. This is a means of depicting ancestor-descendant relationships and who is related who (freeman, 2nd canadian edition section 27. 1). The cladistic approach to deriving phylogentic trees is based on identifying shared, derived characteristics (or synapomorphies) in the species (cid:271)ei(cid:374)g studied.
