My only real point here was that if we’re going to stake the claim that “innovation is human nature”, we have to consider a broader scope of the word to include forms of innovation that are mostly invisible to archaeologists - the problem then being that we are making completely unsupported claims to do so.
All those things you mentions have been around since prior to the neolithic revolutions… Plus a whole bunch of tool making.
