Our skulls are the most important bones in our body, as they protect our brain, the center of our thinking, feeling and moving. Everything depends on the brain. Since animals depend on their brain, and often on their face to sense - there are big differences between the skull shape of different animals, as they have gone through individual evolutionary tracks to get to where they are. And so, a racoon's skull would be very different to a cat's. So, do you think you have the wisdom and the keen eye to guess which is which?
