       | This doesn't seem as mysterious to me as the article suggests. We
       | were still primarily roaming hunters 1.4m years ago. It's not
       | difficult to imagine the uses a more aerodynamic rock would
       | have...namely, you could be more accurate throwing it.
       | 
       | But I'm sure this occurred to researchers, so maybe they're
       | expressing this as "there is no evidence of how they were used"
       | and not "we don't have some good ideas."

         | Witness arrowheads - every plowed field in the American midwest
         | has arrowheads. Because they were used for thousands of years,
         | and lost for thousands of years.

           | across the area.
           | 
           | Combine that with the fact that we're temporally very close
           | to the Indigenous occupation. Whereas there's over a million+
           | years of geological processes to affect those artifacts
           | original provenance.
           | 
           | Also, if we haven't been looking for crudely rounded stones
           | we aren't going to have much of a sample size to say whether
           | or not they are, to use archeologist's favorite word,
           | ubiquitous.
           | 
           | I'd wager most people aren't aware that spheres aren't common
           | in nature.

           | 
           | Maybe you have passed such things multiple times without ever
           | recognizing their true origins!
