Taxonomy is the branch of Science, in which we study the Classification of Organisms. On discovering an unknown organism, begin classification by looking for anatomical features that appear to have the same function as those found on other species.
In order to correctly classify an organism, scientists use many modern tools.
1.Morphology describes the physical characteristics of an organism. Typically, this is enough information to place the organism within a domain and kingdom.
2.DNA and biochemical analysis allow scientists to test less visible, but distinguishing, characteristics.
3.Comparing embryology allows scientists to group organisms that share common fetal development.
4.Evolutionary phylogeny describes the evolutionary relationships between organisms.These relationships are deduced based on shared traits that may have been passed from ancestor to new species. Traits may include physical traits (ex. presence of jaws), or may be genetic traits (shared genes).
