Sheeps Tell sheeps that they are alike and perhaps, the will wish to be different. The same as apes, sheeps (in recent studies) can recognize many faces (around 50 sheeps and 10 human beings) and yet are able to distinguish the faces 2 years later. Familiar faces calm down them, and can recognize either happy ones or angry ones (of course, the prefer the happy faces). These are amazing skills in an animal which is not known as a smart one.
