That applies to other animals, but not humans. It's almost bizarre that you would assert that because the exact opposite is true. Humans are in every way more "advanced" than other animals on the planet precisely because the information they pass down is useful, comprehensive, and widespread. The last few thousand years has seen the information that gets "passed down" become systemic, and prolific. "Overlap" has nothing to do with anything, as anyone at any age can access a large percentage of important human knowledge going back hundreds to thousands of years, and it's really pretty easy to do so.
