Explain the basic ideas of natural selection proposed by Charles Darwin
What will be an ideal response?
Darwin's ideas included the following: (1 ) Within a species there is variation, and some of this variation has a genetic basis; (2 ) some individuals have more surviving offspring than do others because their particular inherited characteristics make them better suited to their environment; and (3 ) traits of more successful individuals become more common in the population.
