These gorillas being the same mammals as humans also respond and demand things like humans in respective order. For example when they have to meditate they would sit silent and alone, when they have to laugh they would like good companions etc. In a nutshell they are the only mammals that resemble in most of the orders to humans than any other class or phyla does. Have a look at them and see what do you see.
