1. Basic unit of classification of living beings. Formerly regarded as the unit of evolution of organisms, the species that lent space to the local population (deme). (Embrapa, Glossary). 2. Species (Latin: species, "type" or "look", abbreviated "spec." Or "sp." Natural, or "spp." Plural), is a fundamental concept of biology which designates the basic unit of taxonomic system used in scientific classification of living things. Although there are multiple definitions, none of them are consensual [1], the concept is structured on the creation of groups of individuals (specimens) with deep structural and functional similarities with each other, resulting from shared an identical karyotype, expressed in the chromosomal structure similar diploid cells, which gives them biochemical uniformity and the capacity to reproduce among themselves, originating fertile offspring having the same general typeface [2], a process that when involving a sexed being, must permit fertile offspring of either sex . Although there have been proposed more precise multiple definitions, the difficulty in finding a universal definition for the concept led to the emergence of the so-called problem of species[1] and the adoption of flexible formulations used pragmatically according to the specificities of the biological group which The concept is applied.
