Detailed explanation-1: -Darwin’s observations that led to his theory of natural selection are: Overproduction-all species will produce more offspring than will survive to adulthood. Variation-there are variations between members of the same species.
Detailed explanation-2: -What two ideas from geology were important to Darwin’s thinking? First, he asked himself: If the Earth could change over time, might life change as well? Second, he realized that it would have taken many years for life to change the way he suggested. This would mean the Earth was extremely old.
Detailed explanation-3: -Darwin states two inferences from two observations; Observation-1: members of the population vary in their inherited traits. Observation-2: All species can produce more offspring than the environment can support, but many of the offspring fail to survive and reproduce.
