Why was Darwin and Wallace's Theory of Evolution by Natural

Question

Why was Darwin and Wallace's theory of evolution by natural selection revolutionary?
A) It proposed that humans were descended from chimpanzees.
B) It was the first time a biologist had proposed that species changed through time.
C) It dismissed the idea that species are constant and emphasized the importance of variation and change in populations.
D) It proved that individuals acclimated to their environment over time.

Accepted Answer

Darwin and Wallace's theory of evolution by natural selection was revolutionary because it dismissed the previously widely accepted idea that species were constant and unchanging. Instead, it emphasized the importance of variation within and across populations and the role of environmental pressures in shaping the traits that were favored or selected for. This fundamentally changed the way that biologists and scientists approached the study of life on Earth.
