Most people take it for granted that humans are more important than apes.But this assumption has more to do with double standards than biology

Richard Dawkins

Sir, you appeal for money to save the gorillas. Very laudable, no doubt. But it doesn't seem to have occurred to you that there are thousands of human children suffering on the very same continent of Africa. There'll be time enough to worry about gorillas when we've taken care of every last one of the kiddies. Let's get our priorities right, please!

This hypothetical letter could have been written by almost any well-meaning person today. In lampooning it, I don't mean to imply that a good case could not be made for giving human children priority I expect it could, and also that a good case could be made the other way. I'm only trying to point the finger at the automatic, unthinking nature of the speciesist double standard. To many people it is simply self-evident, without any discussion, that humans are entitled to special treatment.

To see this, consider the following variation on the same letter:
Sir, you appeal for money to save the gorillas. Very laudable, no doubt. But it doesn't seem to have occurred to you that there are thousands of aardvarks suffering on the same continent of Africa. There'll be time enough to worry about the gorillas when we've saved every last one of the aardvarks. Let's get our priorities right, please!

This second letter could not fail to elicit the question: "What's so special about aardvarks?" A good question, and one which would require a satisfactory answer before we took the letter seriously. Yet the first letter, I suggest, would not prompt most people to ask the equivalent question: "what's so special about humans?" As I said, I don't deny that this question, unlike the aardvark question, very probably has a powerful answer. I am merely criticising the unthinking assumption that in the case of humans, the question doesn't arise.

"'Human',to the discontinuous mind, is an absolute concept.There can be no half measures. And from this flows much evil."

The speciesist assumption that lurks here is very simple. Humans are humans and gorillas are animals. There is such an unquestioned yawning gulf between them that the life of a single human child is worth more than the lives of all the gorillas in the world. The worth of an animal's life is just its replacement cost to its owner - or, in the case of a rare species, to humanity. But tie the label Homo sapiens even to a tiny piece of insensible, embryonic tissue, and its life suddenly leaps to infinite uncomputable value.

This way of thinking characterises what I want to call the discontinuous mind. We would all agree that a six-foot woman is tall, and a five-foot woman is not. Words like "tall" and "short" tempt us to force the world into qualitative classes, but this doesn't mean that the world really is discontinuously distributed. Were you to tell me that a woman is five feet nine inches tall, and ask me to decide whether she should therefore be called tall or not, I'd shrug and say: "She's five foot nine, doesn't that tell you what you need to know?" But the discontinuous mind, to caricature it a little, would go to court (probably at great expense) to decide whether the woman was tall or short. Indeed, I hardly need to say caricature. For years, South African courts have done a brisk trade adjudicating whether particular individuals of mixed parentage count as white, black, or coloured.

The discontinuous mind is ubiquitous. It is especially influential when it afflicts lawyers and the religious (not only are all judges lawyers, but a high proportion of politicians are too-and all politicians have to woo the religious vote). Recently, after giving a public lecture, I was cross-examined by a lawyer in the audience. He brought the full weight of his legal acumen to bear on a nice point of evolution. If species A evolves into a later species B, he reasoned closely, there must come a point when a mother belongs to the old species A and her child belongs to the new species B. Members of different species cannot interbreed with one another. I put it to you, he went on, that a child could hardly be so different from its parents that it could not interbreed with their kind. So, he wound up triumphantly, isn't this a fatal flaw in the theory of evolution?

Ring around the world
But it is we who choose to divide animals up into discontinuous species. According to the evolutionary view of life, there must have been intermediates, even though, conveniently for our naming rituals, they are usually extinct: usually but not always. The lawyer would be surprised and, I hope, intrigued by so-called ring species.

The best-known case is the herring gull versus the lesser black-backed gull. In Britain these are clearly distinct species, quite different in colour. Anybody can tell them apart. But if you follow the population of herring gulls westwards round the northern hemisphere to North America, then via Alaska across Siberia and back to Europe again, you will notice a curious fact. The "herring gulls" gradually become less and less like herring gulls and more and more like lesser black-backed gulls.

It turns out that our European lesser black-backed gulls are actually the other end of a ring that started out as herring gulls. At every stage around the ring, the birds are sufficiently similar to their neighbours to interbreed with them. Until that is, the ends of the continuum are reached, in Europe. At this point the herring gull and the lesser blacked-backed gull never interbreed. The only thing that is special about ring species is that the intermediates are still alive. All pairs of related species are potentially ring species. The intermediates must have lived once. It is just that in most cases they are now dead.

The trained discontinuous mind of the lawyer insists on placing individuals firmly in this species or that. He does not allow for the possibility that an individual might lie halfway between two species, or a tenth of the way from species A to species B. Self-styled pro-lifers, and others that indulge in footling debates about exactly when in its development a fetus "becomes human" exhibit the same discontinuous mentality. It is no use telling these people that, depending upon the human characteristics that interest you, a fetus can he "half human" or "a hundredth human". "Human", to the discontinuous mind, is an absolute concept. There can he no half measures. And from this flows much evil.

The word "apes" usually means chimpanzees, gorillas, orang- utans, gibbons and siamangs. 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 orang-utans. There is no natural category that includes chimpanzees, gorillas and orang-utans but excludes humans. The artificiality of the category "apes", as conventionally taken to exclude humans, is demonstrated by Figure 1. This family tree shows humans to be in the thick of the ape cluster.

Evolution of the apes
Figure 1 It is more natural to group humans with certain other primates, as in the category "African Apes" (bottom), than to exclude them, as the conventional category "Apes" does (above)

All the great apes that have ever lived, including ourselves are linked to one another by an unbroken chain of parent-child bonds. The same is true of all animals and plants that have ever lived, but there the distances involved are much greater. Molecular evidence suggests that our common ancestor with chimpanzees lived, in Africa, between five and seven million years ago, say half a million generations ago. This is not long by evolutionary standards.

Events are sometimes organised at which thousands of people hold hands and form a human chain, say from coast to coast in the US, in aid of some cause or charity.Let us imagine setting one up along the equator, across the width of our home continent of Africa. It is a special kind of chain, involving parents and children, and we will have to play tricks with time in order to imagine it. You stand on the shore of the Indian Ocean in southern Somalia, facing north, and in your left hand you hold the right hand of your mother. In turn she holds the hand of her mother; your grandmother. Your grandmother holds her mother's hand, and so on. The chain wends its way up the beach, into the arid scrubland and westwards towards the Kenya border.

How far do we have to go until we reach our common ancestor with the chimpanzees? It is a surprisingly short way. Allowing one yard per person, we arrive at the ancestor we share with chimpanzees in under 300 miles. We have hardly started to cross the continent; we are still not halfway to the Great Rift Valley. The ancestor is standing well to the east of Mount Kenya, and holding in her hand an entire chain of her lineal descendants, culminating in you standing on the Somali beach.

"All the great apes that have ever lived,including ourselves,are linked by an unbroken chain of parent child bonds"

The daughter that she is holding by her right hand is the one from whom we are descended. Now the arch-ancestress turns eastward to face the coast, and with her left hand grasps her other daughter, the one from whom the chimpanzees are descended (or son, of course). The two sisters are facing one another, and each holding their mother by the hand. Now the second daughter, the chimpanzee ancestress, holds her daughter's hand, and a new chain is formed, proceeding back towards the coast. First cousin faces first cousin, second cousin faces second cousin, and so on. By the time the doubled-back chain has reached the coast again, it consists of modern chimpanzees. You are face to face with your chimpanzee cousin, and you are joined to her by an unbroken chain of mothers holding hands with daughters.

If you walked up the line like an inspecting general-past Homo erectus, Homo habilis, perhaps Australopithecus afarensis -and down again the other side (the intermediates on the chimpanzee side are unnamed because, as it happens, no fossils have been found), you would nowhere find any sharp discontinuity. Daughters would resemble mothers just as much (or as little) as they always do. Mothers would love daughters, and feel affinity with them, just as they always do. And this hand- in-hand continuum, joining us seamlessly to chimpanzees, is so short that it barely makes it past the hinterland of Africa, the mother continent.

Breeding with missing links
Our chain of African apes, doubling back on itself, is in miniature like the ring of gulls round the northern hemisphere, except that the intermediates happen to be dead. The point I want to make is that, as far as morality is concerned, it should be incidental that the intermediates are dead. What if they were not? What if a clutch of intermediate types had survived, enough to link us to modern chimpanzees by a chain, not just of hand-holders but of interbreeders? Remember the song, "I've danced with a man, who's danced with a girl, who's danced with the Prince of Wales"? We can't (quite) interbreed with modern chimpanzees, but we'd need only a handful of intermediate types to be able to sing: "I've bred with a man, who's bred with a girl, who's bred with a chimpanzee."

It is sheer luck that this handful of intermediates no longer exists. ("Luck" from some points of view: for myself, I should love to meet them.) But for this chance, our laws and our morals would be very different. We need only discover a single survival; say a relict Australopithecus in the Budongo Forest, and our precious system of norms and ethics would come crashing about our ears. The boundaries with which we segregate our world would be all shot to pieces. Racism would blur with speciesism in obdurate and vicious confusion. Apartheid, for those that believe in it, would assume a new; and perhaps a more urgent, import.

Chimera
The discovery of a single chimpanzee/human survivor would demolish our system of ethics.

But why, a moral pliilosopher might ask, should this matter to us? Isn't it only the discontinuous mind that wants to erect barriers anyway? So what if, in the continuum of all apes that have lived in Africa, the survivors happen to leave a convenient gap between Homo and Pan?

Surely we should, in any case, not base our treatment of animals on whether or not we can interbreed with them. If we want to justify double standards-if society agrees that people should be treated better than, say, cows (cows may be cooked and eaten, people may not)-there must be better reasons than cousinship. Humans may be taxonomically distant from cows, but isn't it more important that we are brainier? Or better; following Jeremy Bentham, that humans can suffer more-that cows, even if they hate pain as much as humans do (and why on earth should we suppose otherwise?), do not know what is coming to them?

Suppose that the octopus lineage had happened to evolve brains and feelings to rival ours; they easily might have done so. The mere possibility shows the incidental nature of cousinship. So, the moral philosopher asks, why emphasise the human/chimp continuity? Yes, in an ideal world we probably should come up with a better reason than cousinship, for, say, preferring carnivory to cannibalism. But the melancholy fact is that, at present, society's moral attitudes rest almost entirely on the discontinuous, speciesist imperative.

And what if somebody succeeded in breeding a chimpanzee/ human hybrid? I can assert, without fear of contradiction, that the news would be earth-shattering. Bishops would bleat, lawyers would gloat in anticipation, conservative politicians would thunder; socialists wouldn't know where to put their barricades. The scientist that achieved the feat would be drummed out of politically correct common rooms; denounced in pulpit and gutter press; condemned, perhaps, by an ayatollah's fatwah. Politics would never be the same again, nor would theology, sociology psychology; or most branches of philosophy. The world that would be so shaken, by such an incidental event as a hybridisation, is a speciesist world indeed, dominated by the discontinuous mind.

I have argued that the discontinuous gap between humans and "apes" that we erect in our minds is regrettable. I have also argued that, in any case, the present position of the hallowed gap is arbitrary the result of evolutionary accident. If the contingencies of survival and extinction had been different, the gap would be in a different place. Ethical principles that are based upon accidental caprice should not be regarded as though they are cast in stone.


Speciesism

Animals are not brethren, they are not underlings; they are other nations, caught with ourselves in the net of life and time.
HENRY BESTON

Another striking fact now rendered familiar, even platitudinous, by triumphs of recent genetic science is how closely all living things are related. Humans share more than half their genes with worms and fruit-flies, and almost all their genes with chimpanzees. Yet this intimate familyhood of life does not stop people from spearing worms onto fish-hooks, or testing drugs on chimpanzees. Nothing surprising there, you might say, given the way humans treat humans; in the face of gas chambers, racism, war and other avocations, what chance has a monkey or a cow? There are lessons to be learned from the way humans justify their treatment of animals - not least of those evolutionarily closest to them - namely, the apes. Apes, especially gorillas, have long been demonised in film and literature. Their similarity to us is used not as proof of kindred, but as a means of symbolising the supposed bestiality within us. Thus when Dr Jekyll drinks his potion he exposes a mythologised savage inheritance; his hands grow hairy, his brow beetles, his teeth enlarge: he becomes a horrifying gorilla-man. If it is not violence it is stupidity which marks the ape, betokened by tree-swinging, armpit-scratching and gibbering. You insult a person if you call him an ape. Yet apes are intelligent, inquisitive, affectionate and sociable, with capacities for suffering and grief that match our own, and with a grave beauty and dignity which recalls Schopenhauer's remark that 'There is one respect in which brutes show real wisdom when compared to us - I mean their quiet, placid enjoyment of the present moment.' There is a parallel between our excuses for maltreating apes and those for maltreating fellow humans. We locate a difference that we find threatening, or that we despise; we thereby make the other fully other, so that we can close the door of the moral community against him, leaving him outside where our actions cannot be judged by the same standards as apply within. Racism and speciesism are thus the same thing - they are myths about who belongs and who is alien. In their book The Great Ape Project published some years ago, Paola Cavalieri and Peter Singer entered a plea for humankind to 'admit our fellow Great Apes - the chimpanzees, gorillas and orangutans - to the same moral community as ourselves, thereby according them rights to life, to liberty, and to protection against torture - especially the kind of torture inflicted in the name of scientific research.' In the face of the genetic and behavioural evidence, there is no good reason why the moral respect and consideration that applies between humans should not apply between humans and apes. But note: the moment that the boundaries of morality are extended in this way, there is no obvious place to stop. All animate nature comes within the purview of ethics; and that, arguably, is as it should be. The world divides into vegetarians and those that eat them. Thoreau wrote, 'I have no doubt that it is a part of the destiny of the human race, in its gradual improvement, to leave off eating animals, as surely as the savage tribes have left off eating each other.' There are plenty who argue that it is not immoral to eat a cow, especially if it has lived well beforehand. Lovers of cats and dogs would think it cruel to eat their pets, though, and once again the reason is the boundary: cats and dogs, horses and yet hamsters, have become quasi-citizens of the human world, and our treatment of them is premised on the same kind of concern for their interests as we show to other humans. We would not crowd dogs into a closed lorry as we do sheep when they are sent on long export journeys; that is a happy fact. But it is an unhappy fact that we crowd sheep into lorries, for sheep can suffer thirst and panic just as dogs - and humans - do. Humanity's record with animals is poor. 'We have enslaved the rest of the animal creation,' wrote Dean Inge, 'and have treated our distant cousins in fur and feathers so badly that beyond doubt, if they were able to formulate a religion, they would depict the Devil in human form.' Some think that sentimental do-goodery over animals is a distraction from more significant moral matters. Perhaps; but a person's integrity is never more fully tested than when he has power over a voiceless Creature; and the route from pulling wings off flies to committing crimes against humanity is not a notably circuitous one.
