Answer 2

At the time of Charles Darwin's expedition, most people in England believed in the theory of creationism, which posits that all living things were created by a divine being (God) in their current form. This belief was largely influenced by religious teachings and had been the dominant view for centuries. Darwin's theory of evolution by natural selection challenged this notion by proposing that species evolve over time through a process of adaptation and natural selection.
