We are now developing a technique that enables them to keep their natural behaviour going. There were lots of rules you had to learn, you probably had to wear a uniform and you soon found out that teachers were the boss of the classroom. You will see the big male with his hair standing up on end so that he he looks very big. He will look half his size again and he'll start monstering. He will use his whole body and move towards the other individuals and they will start going down in a very low position which means 'Yes, you're the boss and if I'm lower than you, I will look up at you as you're the boss'.
Chimpanzees are humans' closest animal relative.
Their DNA is almost identical to ours. Children you'll notice have this little white tuft on their bottom and they have that until they're five years of age. Basically this shows other members of the group that they don't mean any trouble, they just don't actually know the rules of the group yet, and that they will keep out of each other's way. They will go and take food from adults, and when they do that they actually don't mean any harm, so the adults just keep away from them or humour them. They distract them.
