The common way that a species is defined in biology is in terms of <u><em>reproductive isolation</em></u>. This means that all organisms that are similar enough to produce fertile offspring in nature.
Explanation:
Reproductive isolation can be described as the ability of organisms to live in a place but mate and reproduce with the organisms which are alike to produce fertile offsprings. The phenomenon of reproductive isolation allows organisms of a species to mate and produce fertile offsprings. The production of fertile offspring is very necessary for the continuation of a species on the Earth. Those organisms in a species which are better adapted to live in the environment are able to reproduce and produce fertile offspring.
