In ecology‚ the competitive exclusion principle‚ sometimes referred to as Gause’s law of competitive exclusion or just Gause’s law‚ is a proposition which states that two species competing for the same resources cannot coexist if other ecological factors are the same. When one species has even the slightest advantage or edge over another‚ then the one with the advantage will dominate in the long term.

There are four types of evolution‚ those being adaptive‚ convergent‚ divergent‚ and co-evolution. Divergent evolution is when two or more animals originate from a common genetic base. To prove divergent evolution in animals‚ the Ursus Maritimus or polar bear is an example. Divergent evolution is when similar animals branch off becoming dissimilar as time goes. Divergent evolution occurred 125‚000 years ago when brown bears were isolated from their ancestors. This movement got them stranded and
