WebThere are several different types of speciation (how a new plant or animal species comes to be). Two of these types include allopatry and sympatry. Allopatric speciation happens when a species is divided into 2 separate groups which do not come into contact with one another (they become isolated groups) (Nat Geo Education).

The term sympatric comes from the English prefix sym- meaning “same” or “together” and the Greek word patris which means “fatherland.”. This … The lack of geographic isolation as a definitive barrier between sympatric species has yielded controversy among ecologists, biologists, and zoologists regarding the validity of the term. As such, researchers have long debated the conditions under which sympatry truly applies, especially with respect to parasitism.

Webshifted from the allopatry–sympatry debate to identifying the evolutionary forces involved in speciation (Schilthu-izen, 2001). The relative contribution of natural selection and of other evolutionary forces is a key issue (Mallet, 2001; Rundle & Nosil, 2005). Speciﬁcally, the importance of adaptation to diverging environmental conditions has For some time it was difficult to prove that sympatric speciation was possible, because it was impossible to observe it happening. It was believed by many, and championed by Ernst Mayr, that the theory of evolution by natural selection could not explain how two species could emerge from one if the subspecies were able to interbreed. Since Mayr's heyday in the 1940s and 50s, mechanisms have been proposed that explain how speciation might occur in the face of interbre…
