Answer: This is the answer to the question
Step-by-step explanation:
Thomas Kuhn argued that science does not evolve gradually toward truth.
Science has a paradigm that remains constant before going through a paradigm shift when current theories can’t explain some phenomenon, and someone proposes a new theory.
A scientific revolution occurs when: (i) the new paradigm better explains the observations and offers a model that is closer to the objective, external reality; and (ii) the new paradigm is incommensurate with the old.
For example, Lamarckian evolution was replaced with Darwin’s theory of evolution by natural selection.
