Evolutionary biologists and taxonomists are wrestling with these issues and have proposed many other species definitions: evolutionary, phylogenetic, ecological, cladistic, morphological, and more (see Claridge et al. 1997 and Coyne and Orr 2004 for reviews). ” The differences among definitions would be an academic issue except that species identified by different definitions do not always correspond to one another.
Conservation biologists need to be aware of the debate over species definitions because it can have profound implications (Agapow et al. 2004; Mace 2004), but they cannot allow themselves to be paralyzed by it. It is better to use a fallback definition such as a species is “what a competent taxonomist says it is” (Stevens 1990), rather than do nothing for lack of definitive information. Fortunately, uncertainty over species definitions actually bolsters the overall goal of maintaining biodiversity because it highlights the critical importance of maintaining diversity below the species level, namely genetic diversity.
