I’ve spun this discussion into a separate thread as I think it is a possibly interesting discussion but not really on point to continue here.
To the point of this thread is @thorny_locust’s point: whether or not protection from the elements is needed, how long until some clothing was created to cover whatever area of the body got designated as not for public viewing, or (and include decoration or markings here) to designate social status within the group? Is that fairly hardwired in some manner, the exact manner being culturally determined.
So the concept of tool use is, you think pretty hardwired, and not culturally learned? And creating more complex tools should be a fairly automatic thing?
Not debating the point. I think I agree with the first part. Not as sure about the second. I think the concept of building new tools using other tools would a while for the Euraka moment.
