What does Darwin's theory of evolution propose as the driving force behind the development of new species?
  1. Mutations
  2. Adaptation
  3. Inheritable variations
  4. Large differences arising suddenly in a population

Solution

Darwin's theory of evolution proposes that the driving force behind the development of new species is adaptation, where variations that make resource utilization better for a few (adapted to the habitat better) will enable only those to reproduce and leave more progeny, leading to a change in population characteristics and new forms appearing to arise.
