Theory of evolution involved two controversial ideas. Replaced view of a static world (difficult to accept) Replaced view that the causes of all phenomena had to have a purpose. Evolution is a blind mechanistic process that has no foresight, like gravity, blizzards it just happens. It"s not to bring out speciation and etc. , First to use the term evolution (caused a paradigm shift) Linear line rather than branching view of evolution.
