Chimps killing with weapon.

Just saw a Nat. Geo. "Chimps: Next of kin".

A male chimp had a heavy stick he used to jab into a hollow
trunk to kill a bush baby for his lunch. ( a spear? )

And they brought a set of tools to a termite
nest to probe for insects, 2 or 3 diff. size sticks.

Archaeologists found chimp tools used
for breaking nuts.

Pithecines  may not be the first tool users.
Why have chimps not progressed to Bipedalism
while man did?


Things are a changing...
