The best adapted organisms are able to survive. A process whereby species which have traits that enable them to adapt in an environment survive and reproduce passing on their genes to the next generation.

I nherited variation exists within the population. Evolution by natural selection occurs when certain genotypes produce more offspring than other genotypes in response to the environment. Is the theory that over generations individuals within a population who are either not suited to their environment or have a genetic. The most desirable characteristics get passed down.
