The process where organisms adapt to their environment with the purpose to survive is known as natural selection The theory of natural selection says that the design in nature changes so we change to adapt to the environment. The scientists who created this theory is Charles Darwin. The theory is basically saying that this process is caused by evolution and adaptation. The way we study natural selection is by looking at three main points: variation in traits, differential reproduction and heredity. At the end we look at the results and see the benefactor and the outlier.
