[Responding to the Bishop of Oxford, Samuel Wilberforce's question whether he traced his descent from an ape on his mother's or his father's side]

A man has no reason to be ashamed of having an ape for his grandfather. If there were an ancestor whom I should feel shame in recalling it would rather be a man — a man of restless and versatile intellect — who … plunges into scientific questions with which he has no real acquaintance, only to obscure them by an aimless rhetoric, and distract the attention of his hearers from the real point at issue by eloquent digressions and skilled appeals to religious prejudice.

Once it's been proved to you that you're descended from an ape, it's no use pulling a face; just accept it. Once they've proved to you that a single droplet of your own fat must be dearer to you than a hundred thousand of your fellow human beings and consequently that all so-called virtues and duties are nothing but ravings and prejudices, then accept that too, because there's nothing to be done.

Demanding an “ape-man” is actually just as silly as asking to see a mammal-man, or a half-human, half-vertebrate. How about a half dachshund, half dog? It’s the same thing. One may as well insist on seeing a town half way between Los Angeles and California. Because the problem with bridging the gap between humans and apes is that there is no gap because humans are apes –definitely and definitively. The word, “ape” doesn’t refer to a species, but to a parent category of collective species, and we’re included. This is no arbitrary classification like the creationists use. It was first determined via meticulous physical analysis by Christian scientists a century before Darwin, and has been confirmed in recent years with new revelations in genetics. Furthermore, it is impossible to define all the characters exclusively indicative of every known member of the family of apes without describing our own genera as one among them. Consequently, we can and have proven that humans are apes in exactly the same way that lions are cats, and iguanas are lizards, and whales are mammals. So where is the proof that humans descend from apes? How about the fact that we’re still apes right now!

We admit that we are like , but we seldom realise that we are apes. Our common ancestor with the chimpanzees, bonobos and gorillas is much more recent than their common ancestor with the Asian apes — the and orangutans. There is no natural category that includes chimpanzees, gorillas and orangutans but excludes humans.

I assume he was descended from apes like all the rest of us, but clearly in his case it had been a fairly gentle slope.

If then the question is put to me whether I would rather have a miserable ape for a grandfather or a man highly endowed by nature and possessed of great means of influence and yet employs these faculties and that influence for the mere purpose of introducing ridicule into a grave scientific discussion, I unhesitatingly affirm my preference for the ape.

One of the legacies of being an ape is intergroup violence.

So there he stands, our vertical, hunting, weapon-toting, territorial, neotenous, brainy, Naked Ape, a primate by ancestry and a carnivore by adoption, ready to conquer the world. But he is a very new and experimental departure, and new models frequently have imperfections. For him the main troubles will stem from the fact that his culturally operated advances will race ahead of any further genetic ones. His genes will lag behind, and he will be constantly reminded that, for all his environment-moulding achievements, he is still at heart a very naked ape.

We have to face the fact that we are the descendants of apelike ancestors. The truth, at first sight, is often ugly and repulsive to our personal feelings, but when it is the truth, its ultimate effects on us are always salutary. ...
... Man's brain does not stand as a thing apart; it is the culmination of an ascending series. There is no part of it and no function manifested by it that cannot be traced to humble beginnings lower in the animal scale. And what we postulate for man's brain we must in all justice apply to that of the ape, the dog, and all other beasts.

* My father was a mulatto, my grandfather was a Negro, and my great-grandfather a monkey. You see, Sir, my family starts where yours ends.

[Saying that humans are related to apes is] an insult to apes. Experts say that violence is unknown among the creatures. They are generally gentle. They don't need to be continually policed so that they don't rape and murder like progressive man.

Nevertheless, it is even harder for the average ape to believe that he has descended from man.

All but one person I met who claimed Indian blood claimed it on their grandmother's side. I once did a projection backward and discovered that evidently most tribes were entirely female for the first three hundred years of white occupation. No one, it seemed, wanted to claim a male Indian as a forebear. It doesn't take much insight into racial attitudes to understand the real meaning of the Indian-grandmother complex that plagues certain whites. A male ancestor has too much of the aura of the savage warrior, the unknown primitive, the instinctive animal, to make him a respectable member of the family tree. But a young Indian princess? Ah, there was royalty for the taking.

You're an ape for the exact same reason that you are a mammal.
