Reproductive Isolation
Picture a flood that changes the course of a river, dividing not only the landscape in half, but also a population of deer. The deer can no longer interact and, over hundreds of years, the two deer populations evolve, or change. Eventually, the river dries up and the two groups of deer are able to mingle once again. However, they are no longer able to mate because they are no longer the same species.
A species is a group of living organisms, such as animals or plants, that can interbreed or exchange genes. The above example of the deer is a case of speciation, or when one species becomes two or more, due to evolution.
Many things can separate one population into two or more groups, like shifting continents or lava flows. During their time apart, the deer experienced changes to the point of reproductive isolation. This refers to when two groups of animals live close enough to one another to interact, but are unable to interbreed with one another.
There are many reasons why two organisms cannot mate and they can be divided into the two major divisions - pre-zygotic barriers and post-zygotic barriers.

Reproductive isolation
The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviours and physiological processes critical for speciation. They prevent members of different species from producing sffspring, or ensure that any offspring are sterile. These barriers maintain the integrity of a species by reducing gene flow between related species.
The mechanisms of reproductive isolation have been classified in a number of ways. Zoologist Ernst Mayr classified the mechanisms of reproductive isolation in two broad categories: pre-zygotic for those that act before fertilization (or before mating in the case of animals) and post-zygotic for those that act after it.The mechanisms are genetically controlled and can appear in species whose geographic distributions overlap (sympatric speciation) or are separate
