Tell Me Why?

This is a concept developed by Charles Robert Darwin (12 February, 1809 – 19 April, 1882), a British naturalist who laid the foundations of the Theory of Evolution. Natural Selection is the basis for the Theory of Evolution - the natural process of the evolution of organisms best adapted to the environment. Natural Selection is also known as the 'survival of the fittest' in which certain genes produce specific characteristics which make one animal more fit to survive than another animal in a particular environment. These animals or group of animals which are 'survival of the fittest will be more abundant in the next generation since they are able to live and reproduce therefore passing on these traits (genes) to their off spring.

Charles Darwin natural selection explains that nature allows organisms (plants and animals) that have heritable favorable traits (advantageous genetic characteristics) to be well adapted to their environment and to be the best fitted to survive in their respective environment. As such, ensuring that they both live and reproduce thus passing on these heritable favorable traits on to their off springs - the future generations. Their greater reproductive success therefore ensures that these heritable favorable traits are common in their successive generations. Those organisms with less or unfavorable traits will become less common since they are less adapted to their environment. This means that these organisms will gradually be eliminated over many generations and will eventually die out (become extinct) due to their unfavorable traits that make them have a lesser chance of survival and reproduction.
