This problem can be eliminated by using the general idea of specie as an evolving whole which also includes the non-sexual organisms. In order to identify the wide variety of specie, two methods, biological species concept and phylogenetic species concept have been proposed. According to the biological species concept, the critical criterion for identification is generative isolation. Specifically, if two different populations do not thwart in nature, or if they fail to produce viable and ra nk offspring when matings take place, then t! hey are considered distinct...If you want to enamor a full essay, order it on our website: OrderEssay.net
