If species evolve, we are part of this evolution. Darwin must be respected not oly for his speculative thoughts about evoltion, but for having pointed out a commom ancestor of men and primates in a time when one did not even consider the existence of a molecule of life, our DNA. Today, with all technological breakthroughs, it is easy to find similarities and even to define new similarities lines among the organisms. There is a reason to the fact that we and the chimpanzees share 99,4% of our functional DNA, which confirms what Darwin used to suppose.

Nevertheless, together with these confirmations, new doubts, new questions. After all, being practically humans (or practically chimpanzees, in our case), what do chimpanzees thinkω We know that humans are able to think and feel. But would it be only humans the ones who have these charactheristicsω Although some scientists insist on deny it, the answer is, with no doubt, negative.

According to researchers, to think it is necessary that one has councious. And to reach that, self-knowledge of one\’s own abilities is necessary, to know that one knows something and to know that the other one has councious for similarity. And, as long as it is something difficult to be proved, only human animal would be given this quality. Is it difficult to prove or there is no interest in confirmingω

Billy knows exactly where he lives and what surrounds him. Even though his enclosure is externaly enclosed, eventually a lot of branches from the pinus fall inside it. In the internal area, beside the sink, some refreshment bottles take place and eventually are offered to him. And, by observing what Billy has done, I answer: yes, they think! The refreshments were there for a while and one day Billy went to the external area carrying a piece of branch, that was on the floor, until his food place. From there, he pointed the branch through a hole on the fence and tried to pull the refreshment. Quickly he noticed that the branch was not long enough and he gave up, letting it on the floor.

Do you continue to believe that they do not thinkω That they do not have simbolic ability or have councious about what they makeω And Billy is only one among any other examples that could not be mentioned in this small article.

Darwin did not have tools to prove his ideas and theories, that, even though, were accepted and got right to the point. Then, why not to accept facts, arguing that they can not be submitted to scientific methodologyω Scientific disbeliefω Prejudiceω Darwin, congratulations for having survived until now in this cold and mean world!
