(4) Linnaeus developed his classification system for organisms according to<u> Fixity of species</u>.
Aristotle's thoughts shaped the reason for the western confidence in a fixity of animal species.
Every one of which has a run of the typical structure. Carolus Linnaeus (1707-1778 AD) arranged creatures following a binomial arrangement of classification, giving every specie a particular and conventional name <em>e.g. Homo sapiens (Genus species).</em>
<em>People of an animal varieties are not identical attributes are passed from age to age more posterity are conceived than can endure and just the overcomes of the opposition for assets will replicate.</em>
When two species share a common niche, then one is bound to exclude the other. This is due to the stiff competition for resources. The species with a slight advantage in acquiring the resources will edge out the other species from the environment. This has been demonstrated by George Gauss using two Paramecium species grown in the same media in the lab. <em> P. aurelia</em> outcompetes <em>P. caudatum</em>
