Ever wonder how evolution comes to be? How some species win and others lose? Evolution has many different ways of making organisms all better‚ faster‚ and more adept to live. Four big categories of the mechanisms of evolution are natural selection‚ gene flow‚ genetic drift‚ and mutations. The majority of the time‚ nature goes by a trial and error system that can take up many centuries to come up with a change that is beneficial. Natural selection is the process in which nature removes its mistakes

Also it favors certain traits in a individual
