The organisms that are better adapted to their immediate environment and have greater reproductive success leave a greater representation of their genes in the gene pool of those organisms. Over time the reproductively successful have the majority representation of genes in the gene pool and with this frequency shift evolution has taken place. Evolution is the change in allele frequency over time in a population of organisms. Sometimes, with the proper beneficial mutations and right immediate environment, speciation can take place.
