Sympatric speciation experiments in yeast.

New species come into being when an existing species "splits" into two species. This process is called speciation, and is known to occur via two modes - allopatry (literally meaning different place) and sympatry (same place). In allopatry, individuals of a species are separated physically (by a water body, for instance), and thereafter, the two separated groups evolve independently. The precise environmental conditions in the two regions drive these two groups apart with time, and eventually, the two groups speciatte into distinct species. On the other hand, in sympatry, the individuals are not separated, and speciation event occurs in that environment. Although sympatric mode is considered an important mechanism to generate species, till date, there has been no experimental condition which has exhibited its existence in lab conditions. In this project, we plan on conducting experiments in yeast to exhibit sympatric speciation in lab conditions.
