In fact, we could go away for a million years and come back and these chimpanzees would be doing the same thing with the same sticks for the termites and the same rocks to crack open the nuts.
De facto, podíamos ausentar-nos durante um milhão de anos e regressar e estes chimpanzés estariam a fazer a mesma coisa com os mesmos paus para térmitas e as mesmas pedras para abrir nozes.
