Two year olds and dogs share the same ability to understand adult pointing gestures. If you point with your index finger not lined up with your arm or other most protruding body part (insert 6th grade humor here), neither the dog nor the two year old will get it. However, if you point with everything in the same direction, both man and beast will head that direction. This points to the evolutionary history of humans and dogs becoming “domesticated” together. This also makes me laugh.
