Yes. I suppose if you stretch the definition of tool to include location and the definition of reusability to picking up the same thing twice then monkeys have entered the Stone Age
Along with chimps and birds who would also be reusing the same implements more than once at the same termite mound or nest
Glad we cleared that up with good scientific reasoning
That seems like as cozy a place to shift the goalposts as any. You'll have no argument from me about keeping an eye on chimps and corvids as well.
