By taking this first step in organizing the living world into groups such as there we begin to conceive of nature in a way that allows us to make sense of diversity. To think of fungi as distinct life forms unrelated to plants is to conceive of them in a manner that is different from the recent past when they were considered to be unusual plants. Much biodiversity is undiscovered. An unknown, but probably large, proportion of the species on earth today have not been discovered. Much prospecting is still to be done.
Most biologists actively avoid using undescribed species.
Most diversity occurs in the tropics while most research universities and active biologists are in the temperate regions. A Latin binomial is applied to a species when it is first described. The genus and species names are used to avoid confusion with common names. These binomials are in no sense really scientific and often communicate nothing of interest about a species. The common honeybee is Apis mellifera , and in most cases the common name would serve us as well as the Latin binomial.
