The diversity is one of the most fascinating aspects of the living world. In the last 300 years, from exploration trips - the most famous certainly was Darwin's aboard the Beagle - knowledge about the diversity of life has grown exponentially. Fundamental to its consolidation were the theories about the biological definition of species. Although it is not a consensus, since there are currently several definitions for species, the concept proposed by Mayr (1999) is based on three premises, except:


a) The species is a group of individualistic populations that reproduce in different groups.
b) The species is a group of individuals that can interbreed and produce fertile offspring.
c) The species is a group of individuals that share a common gene pool.
d) The species is a group of individuals that are reproductively isolated from other groups.
