Scientific investigations often lead to the formulation of new scientific questions. The observations Charles Darwin made during his time aboard the H.M.S. Beagle prompted him to ask which question? Do living organisms change over time and, if so, how? Are the finches of the Galapagos Islands the same as those on the mainland? Can selective breeding occur in nature? Can the accumulation of gradual changes in a population lead to a new species over time?

Charles Darwin is known as the man behind the concept of natural selection - that some traits that give relative advantage would appear more and more often, eventually changing the species over time. The correct answer is thus the last one: "the accumulation of gradual changes in a population leads to a new species over time". It especially can't be the first option - we know that organisms chance over time (children become adults) - so we didn't need Darwin to realize that, this is somehting that people have understood for a long time. His discovery was connected to selective breeding, but his major insight was gradual evolution, not the breeding itself.

Charles Darwin observed that the accumulation of gradual changes in a population leads to a new species over time.

Further Explanation:

Scientific experimentations are the logical and practical procedures that determine the efficiency of a particular claim using scientific means. Charles Darwin was the one who gives the theory of evolution that occurred by natural selection. According to Darwin, evolution was descent with modification. There is a common ancestor between the species that changed over time and became new species. Natural selection is the reason why the population grows adapted for well suited to the environment over time.

The pre-existing heritable variation in the group is the prime condition for natural selection to happen in the environment between the species. Natural selection is the process by which the well-suited organism in the population gets selected due to stress in the atmosphere thus evolving the species. In Darwin's book ‘The Origin of Species’, all these facts and information are mentioned, and the ideas of evolution and natural selection are well-reflected.
