Variety of life

Over one and a half million species of animals and over a half-million species of plants are known. To deal with such a large collection of dissimilar forms, certainly, we need some system by which species can be classified in a reasonable way. Many types of classifications are possible. We could, for example, classify flowering plants according to their color, height, or any other character. This type of classification is not meaningful since it does not provide any information about the basic diferences and similarities among different individuals.

All organisms are related to one another at some point in their evolutionary histories. However, some organisms are more closely related than others. Sparrows are more closely related to pigeons than insects. Classification is based on relationships amongst individuals, that is, similarity in form or structure.
