Dear all, 1. Charles Darwin invented the theory of evolution. 2. Charles Darwin developed the theory of evolution. 3. Charles Darwin created the theory of evolution. What are the differences between the three? For me, 1. "He invented the theory" suggests that he came up with something totally new, novel and useful for society. 2. "He developed the theory" suggests that he gradually grew a seed of his idea into the theory over time, but it's not clear how creative that theory is. 3. "He created the theory" says that he made a new theory, but it's not stressing its novelty so much as "he invented the theory". I'm getting confused writing the above myself. I would appreciate your help.
