Who’ll inherit the earth again?
PZ Myers — who I need to add to the blogroll — offers this video of a crow dismantling the barrier between us vaunted Homo sapiens and all those other, lesser animals. Yeehaw!
PZ’s description:
The crow has the job of lifting a bucket with a food reward out of the tube — and all it’s given to do the job is a straight piece of wire. Watch it make a hook in the wire so it can snag the handle of the bucket and lift it out.
Proper citation (thanks, Ian):
