Answer:
c. Most scientist, including Darwin thought species were product of natural processes and changed over time.
Explanation:
Darwin was not the first scientist to think or proposed that the species changed over the time, but in his expedition and through several observations, he concluded that these changes over the time are the consequence of the adaptations of the living things to the environment that surround it.
That is the reason why his theory mixed with Mendel genetics discover, changed the point of view of the evolution in species.
