The correct option is (b) There is variation in inherited traits.

Darwin made the following observations that informed his theory of natural selection: Overproduction, Variation, Selection, Survivors.

<h3>What were the darwins observation?</h3>
  • The first observation is overproduction. This shows that every species has more offspring than will grow up to be adults. Think about all the fish eggs that are produced every year.
  • This suggests that organisms should constantly reproduce, but they do not because mechanisms like food competition, predators, and disease exist to limit population growth.
  • Darwin was able to infer from this that there is a struggle for existence.
  • Darwin's second finding was variation. This suggests that members of the same species exhibit a range of features. For instance, the pattern and color of the stripes on zebras vary. Scales on goldfish might be entirely gold, entirely orange, entirely brown, or a mix of all three.
