The making of the Fittest: Natural Selection and Adaptation
... Natural selection is the process by which individuals in a population who are best adapted to their environment survive and pass on their genes to the next generation more frequently than those individuals who are less well adapted. In this way, favorable traits will increase in frequency in a popul ...
