Goats can follow human instructions

[Catherine]

They have been doing tests with goats using food. When a person spoke in the direction of the food goats found it 60% of the time. Without human clues 
they only found it less than 50% of the time.

Dogs can do this. Chimps cannot. So the issue is not intelligence alone. Is the ability linked to domestication?
That would be one reason why domestication benefits the animal that is domesticated.
It will be interesting to see what further studies show.
