Chimps just have big nuts.

Interesting...thanks.

I disagree with Buster...who gives a rats rear if chimps were using rocks to pound on nuts. Sea Otters were probably doing it long before that (using rocks to open shells). I don't get it.

I found it interesting that they are currently not using computer controlled pneumatic nut crackers.
