Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Example : classic example of natural selection at work is the origin of giraffes' long necks. The ancestors of modern giraffes were animals similar to deer or antelope, with necks of ordinary length.
