Jones: Prehistoric wooden tools found in South America have been dated to 13, 000 years ago  Although scientists attribute these tools to peoples whose ancestors first crossed into the Americas from Siberia to Alaska, this cannot be correct  In order to have reached a site so far south, these peoples must have been migrating southward well before 13, 000 years ago  However, no such tools dating to before 13, 000 years ago have been found anywhere between Alaska and South America  Smith: Your evidence is inconclusive  Those tools were found in peat bogs, which are rare in the Americas
Wooden tools in soils other than peat bogs usually decompose within only a few years
whether the scientists' attribution of tools could be correct in light of Jones's evidence
