Nice piece. Reminds me of something I heard an archaeologist once say about
digging, which goes something like 'one stone's a stone, two stones are a
wall, three stones are a building, and four stones are a palace'. Isn't
there an inherent problem with this kind of 'discovery' though?
Chimps don't do anything to the stones do they (e.g. the flint working of
later hominids)? If that's the case, then how can they be sure they're
looking at a collection of stones used as tools by chimps, and not just at a
collection of stones? (i assume they say more in the Science article).
