The initial observation made by Darwin was that species produce more offspring than what survive, and so many die off, leading to an approximately constant population. This then implies that in order to survive, organisms must compete with one another to see who survives and who dies (struggle). As a result of this competition, traits (inherited variation) that allow an organism to compete more effectively enable it to survive and hence pass the trait to offspring. Hence, over time, these traits accumulate in the population.
