A Quote by Frans de Waal
It is not only visitors to the zoo who are fascinated but uneasy in the presence of chimpanzees; the same is true of scientists. The more they learn about these great apes, the deeper our identity crisis seems to become. The resemblance between humans and chimpanzees is not only external. If we look straight and deep into a chimpanzee’s eyes, an intelligent, self-assured personality looks back at us. If they are animals, what must we be?

If we look straight and deep into a chimpanzee's eyes, an intelligent self-assured personality looks back at us. If they are animals, what must we be?
We admit that we are like apes, but we seldom realise that we are apes. Our common ancestor with the chimpanzees and gorillas is much more recent than their common ancestor with the Asian apes - the gibbons and orangutans. There is no natural category that includes chimpanzees, gorillas and orangutans but excludes humans.
When I left the zoo and I sent my chimpanzees to the sanctuary in Florida and imagined what my chimpanzees went through for 18 years, I'm ashamed of myself.
Chimpanzees are an evolutionary hair's-width from us.... Now imagine a species on Earth, or anywhere else, as smart compared with humans as humans are compared with chimpanzees. How much of the universe might they figure out?
Such is the breathtaking speciesism of our Christian-inspired attitudes, the abortion of a single human zygote can arouse more moral solicitude and righteous indignation than the vivasection of any number of intelligent adult chimpanzees! The only reason we can be comfortable with such a double standard is that the intermediates between humans and chimps are all dead.
There are five kinds of great apes: bonobos, chimpanzees, orangutans, gorillas, and the one which people always think of last: Humans!
Chimpanzees have very strong preferences and aversions that are completely personality-linked. The people who are unsuccessful in working with chimpanzees are those who take this personally.
Chimpanzees are incredibly intelligent. They can learn more than 400 signs of American Sign Language. They have memories for spatial distribution, like numbers on a TV screen, way better than ours. You come onto the emotions: happiness, sadness, fear, and despair - all the things for which I was accused of being anthropomorphic when I ascribed them to chimpanzees.
If you look into their [chimpanzees] eyes, you know you're looking into a thinking mind. They teach us that we are not the only beings with personalities, minds capable of rational thought, altruism and a sense of humor. That leads to new respect for other animals, respect for the environment and respect for all life.
...chimpanzees, bonobos, gorillas, and orangutans are thinking, self-aware beings, capable of planning ahead, who form lasting social bonds with others and have a rich social and emotional life. The great apes are therefore an ideal case for showing the arbitrariness of the species boundary. If we think that all human beings, irrespective of age or mental capacity, have some basic rights, how can we deny that the great apes, who surpass some humans in their capacities, also have these rights?
Through my work with PETA, I have learned a great deal about chimpanzee behavior and the plight of chimpanzees imprisoned in laboratories.
When humans act like animals, they become the most dangerous of animals to themselves and other humans, and this is because of another critical difference between humans and animals: Whereas animals are usually restrained by the limits of physical appetites, humans have mental appetites that can be far more gross and capacious than physical ones. Only humans squander and hoard, murder and pillage because of notions.
Ageing is very rare. We only see it in humans and laboratory animals and in zoo animals and in our pets. Basically, organisms that are protected from the external world. Once you create that protection, you live long enough to see ageing.
Louis [Leakey] was anxious to initiate a scientific study of these chimpanzees. It would be difficult, he emphasized, for nothing was known; there were no guidelines for such a field study; and the habitat was remote and rugged. Dangerous wild animals would be living there, and chimpanzees themselves were considered at least four times stronger than humans. I remember wondering what kind of scientist he would find for such a herculean task.
We now know that the structure of the DNA in humans and chimpanzees differs by only just over one percent. You could even have a blood transfusion from a chimp, provided you have the same blood group.
Chimpanzees, more than any other living creature, have helped us to understand that there is no sharp line between humans and the rest of the animal kingdom. It's a very blurry line, and it's getting more blurry all the time.
