Natural selection is based on the principle that individuals with traits better suited to their environment are more likely to survive and reproduce, passing those traits to the next generation. However, it does not imply that poorly adapted individuals never produce offspring. Even less adapted individuals can reproduce, though their offspring may have lower survival rates.
