Many Great Leaps Forward?

If there was a great leap forward to behavioral modernity ~40,000 years ago, then I think one should logically assert that there was another “great leap forward” ~10,000 years ago in the Middle East with the first farmers. There was also another “great leap forward” ~5,000 years ago ago with the invention of writing. There was another “great leap forward” ~300 years ago in Western Europea with the crystallization of a genuine scientific community.
