Dawkins starts the lecture coming in with a stick insect on his hand. He describes with how much details such a being imitates its environment, its almost like a key that fits a lock. He then shows another insect, namely a Leaf Insect, which basically looks exactly like a dead leaf. He gives some more examples for this amazing imitation of the surrounding, e.g. a Potoo, which looks like a branch of tree and a thorn bug, which gains protection by looking like a rose thorn.
