Natural selection is another way of saying "survival of the fittest" meaning that the organisms better adapted to the habitat will survive. An example of this would be camouflage. Animals who have the ability to camouflage themselves from predators are more likely to live than those who cannot. So... It most likely resulted in evolutionary change because animals needed theses adaptations so over thousands of years, animals who were not able to camouflage now could.
Hope this helps :)))
