Question

The fossils of human ancestors show an increase in complexity as we move forward in the geological time scale. What does this complexity indicate?

a. Evolution is based on the theory of a creator, as explained in many religions.
b. Evolution is a spontaneous and discontinuous process.
c. Evolution is a slow, gradual, and continuous process.

Answer 1

This complexity indicates that "c. Evolution is a slow, gradual, and continuous process," since the only reason such complexity forms is to "adapt" to an ever-changing environment.
