Our Ancestors the Fishes

In his brilliant introduction to the study of animal behaviour, King Solomon’s Ring, Konrad Lorenz tells how the male jewel fish (one of the numerous family of cichlid fishes) gathers his offspring together for return to their nesting hole at night: “He does not coax them along [as is the mother’s way] but simply inhales them into his roomy mouth, swims to the nest, and blows them into the hollow.” [37] To make this practice possible, the baby fishes have a reflex contraction of the swim-bladder which makes them un-buoyant at the necessary times. On one occasion, Lorenz was feeding some of these fishes in his aquarium later than usual, and the descent of a piece of worm attracted the father cichlid just as he was collecting a truant baby. Impelled equally by hunger and parenthood, the fish took them both into his mouth:

It was a thrilling moment. The fish had in its mouth two different things of which one must go into his stomach and the other into the nest. What would he do? … At that moment I would not have given twopence for the life of that tiny jewel fish. But wonderful what really happened! The fish stood stock still with full cheeks, but did not chew. If ever I have seen a fish think, it was at that moment! [37]

That last sentence is best understood with the word ‘seen’ in italics: for the whole book is about watching and admiring, and learning thereby, without making or inheriting assumptions about what is possible to other life-forms. Not the thinking so much, then, but the seeing it happen, is the excitement. And from that sort of sustained attention, as Julian Huxley says in his introduction to Lorenz’s book, it emerges that “the behaviour of fish … is certainly much more extraordinary than most people have any idea of.”

That in fact is the theme of the recent popular study of fish zoology by Jonathan Balcombe, What a Fish Knows: the Inner Lives of Our Underwater Cousins (2016). [I shall come back to Lorenz’s conflicted jewel fish later.] Actually Balcombe’s book is about much more than zoology. Like Lorenz, he insists upon the individual animal. “I felt for that fish” is a typical and (coming at p.5) exemplary statement. The outlook is already there in his title, fixing ‘knowledge’ within the individual rather than in the species or class. And accordingly he uses the word ‘fishes’ for the plural, not the more usual homogenizing collective ‘fish’, “in recognition of the fact that these animals are individuals with personalities and relationships”. (It’s noticeable that the many reviews of the book have conformed to this preference: ‘fishes’ does sometimes sound awkward, but that simply makes the lesson more conscious.) In fact Balcombe distinguishes his book from the “legions of books” about fish biology, ecology, even conservation, to say nothing about the possibly even greater number of books about catching fish (or, to use the miserable ellipsis, ‘fishing’), by presenting What a Fish Knows as a book on behalf of fish” [his italics]. And he dedicates it to “the anonymous trillions”.

That fishes need speaking for is obvious enough. At this early stage of his book, Balcombe merely sketches the frightful depredations to which humans subject them: over a trillion caught for commerce every year; about 47 billion more caught by way of recreation, of which perhaps one third would be killed outright, the rest returned in whatever condition. He leaves the more detailed account to his final chapter ‘Fish out of Water’, coming after the 200 or so intervening pages which have shown the astonishing variety, complexity, sensitivity and beauty of these animals. And the point, again, is not just the wastefulness, ecological havoc, and self-endangering carelessness of this predation, but rather the suffering imposed, because the fishes die as “conscious individuals” and “they do not die nicely”.

The consciousness of fishes, and in particular their ability to feel pain, is still regarded, here and there, as disputable. However, the factuality of it has been well established, at least in the case of one representative species of bony fish (i.e. belonging to the majority order teleosts, the other main order being the cartilaginous fishes or chondrichthyans). The species was the rainbow trout, the subject of a series of studies carried out in Edinburgh University during the first decade of this century, which culminated in Victoria Braithwaite’s book Do Fish Feel Pain? (2010) In fact this book has been cited as “demonstrating that fish feel pain” by the U.K.’s Animals in Science Committee, which advises the government on the welfare of animals in research.

Such studies, however they may advance the interests of fishes in general, themselves involve the killing of many individuals. The extraordinary corpus of knowledge about fish lives and physiology upon which Balcombe bases his book (still only “a tiny fraction of what they know”, he properly reminds us) has mostly been learned in the laboratory or at least in controlled waters with varying degrees of intervention (see, as another example, the study of face-recognition in archer-fish, recounted in this blog at 12 June 2016). Balcombe comments upon this from time to time, often enough unfavourably.

And of course fishes are used in laboratories for purely human interests on a very much larger scale. During the last ten years they have overtaken rats as the second most numerous lab animal in the U.K. , with over 500,000 ‘procedures’ out of the 3.9 million total at the last annual count (2016). At Oxford University, there were 3,106 such procedures in 2007, but 14,737 last year. Among other purposes, fishes are used in order to study genetic abnormalities and infectious diseases, to test drugs and industrial chemicals (infused into their water), and, at Oxford in particular, in cardiac research. The zebra-fish (Danio rerio) is especially preferred, and has been the focus of over 25,000 scientific papers to date, so Jonathan Balcombe says, adding in brackets that “many of these studies are inhumane”.

All this constitutes only a small part of the total trillions, of course, but the two users, science and the food industry, aren’t quite distinct anyway. As with land-animal farming, the research laboratory doesn’t merely serve modern fish-farming; it makes the practice possible. In the chapter ‘Fish out of Water’, Balcombe pays a visit to the Freshwater Institute in West Virginia, a research establishment dedicated to that end. In the “main warehouse”, there are about a dozen tanks. The largest of them contains perhaps 5000 young salmon, each one a foot or so in length, “layers of greenish-brown fishes gliding effortlessly in an eternal circle”.

A 2011 report on the subject of fish welfare in laboratories concluded that “There has traditionally been more tolerance of stress, disease, and mortality as an endpoint [a euphemism, I think, for leaving the fish to die of its own accord] in fish research, compared to research using mammals.” It attributes this disparity partly to the influence of “general attitudes to fish in society.” It may well be true that the low existential status allowed to the fish in western culture (perhaps in all cultures) has permitted a corresponding carelessness in the laboratory, and of course it’s this low status that Balcombe hopes to correct with What a Fish Knows. But although he mixes his science with personal anecdotes, most of his evidence does come, as I’ve mentioned, from scientific research. Evidently, then, the knowledge that would justify a higher esteem has been there (supposing that we should require knowledge of any sort in order to justify respect for fellow-lives); notably it’s been there in the universities. But the moral lesson has not been learned from it.

In an article on fish intelligence, the biologist Culum Brown blames this moral obduracy on a false and partisan concept of evolution, persistent even among scientists: “the deep-rooted notion that the evolution of fossil fishvertebrates follows a linear progression from inferior to superior forms, culminating in humans at the apex.” Since the fish is the most ancient of the animals, some 500 million years old, and since all the other vertebrates evolved from “some common fish-like ancestor around 360 million years ago”, therefore fishes are regarded as belonging to a primitive stage of mental and behavioural development, long grown out of by such as ourselves. However, Professor Brown points out that the fishes themselves have not been stationary during that time; they’ve evolved and diversified to meet or create new circumstances. In fact they “reached peak diversity around 15 million years ago”, which is just the time when the Hominidae family were evolving. “Thus most fish species are no more ‘primitive’ than we are.” That’s no doubt why Jonathan Balcombe calls fishes our “cousins”: we share ancestors with them, as contemporaries.

Still, those ancient fish of the Cambrian period are ancestors to us, and as Professor Brown says, “despite apparent differences between fish and humans [and these apparent differences, so conspicuous and yet irrelevant, no doubt account for much of ArcimboldoFourElementsour careless disesteem of them], evolution tends to be highly conservative; thus, many human traits are identical to or derived from our fishlike ancestors.” If we’re not precisely made of fish, as imagined by the artist Giuseppe Arcimboldo, we were certainly made possible by fishes. This alone, even without all of what Jonathan Balcombe reports of their subtle perceptions, strange and complex life-ways, and beauty of form and colour, should persuade us to honour them, with all the revolution in our behaviour towards them which that would imply.

And in this respect, Lorenz’s story sets a sort of example, even though his fishes were indeed captive ones. We left the jewel fish in a state of indecision, with both food and offspring inside his mouth:

For many seconds the father jewel fish stood riveted and one could almost see how his feelings were working. Then he solved the conflict in a way for which one was bound to feel admiration: he spat out the whole contents of his mouth: the worm fell to the bottom, and the little jewel fish, becoming heavy in the way described above, did the same. Then the father turned resolutely to the worm and ate it up, without haste but all the time with one eye on the child which ‘obediently’ lay on the bottom beneath him. When he had finished, he inhaled the baby and carried it home to its mother.

Some students, who had witnessed the whole scene, started as one man to applaud.

That would have been the highest honour available in the circumstances. Best of all would be to learn about fishes by visiting their own explanatory environments (as indeed Lorenz much preferred to do), and otherwise as far as possible to honour them by leaving them and their waters alone.


Notes and references:

Konrad Lorenz recounts the incident of the jewel fish in King Solomon’s Ring, Methuen and Co., 1952, pp.37-8 (transl. Marjorie Kerr Wilson). Incidentally, Lorenz gives good advice about creating a ‘natural’ aquarium, without for instance the need for artificial aeration, but he’s speaking about locally collected flora and fauna. I doubt that such an environment could be created for the tropical fish, whose use for interior decoration is another wretched instance of the mistreatment of these animals on a very large scale.

Experimenting with Mother

I have a constantly growing collection of ‘They’re smarter than you think’ news stories. Here, for instance, is one from the Washington Post a few months ago. It’s headlined “Make Way for Ducklings; they’re smarter … [etc.]” Make Way for Ducklings is a classic children’s book, published in the U.S.A. in 1941 and often re-printed since then. It would therefore be familiar to most Washington Post readers, and the reference is a sub-editor’s way of sweetening the science. But the main theme of that book is the trouble which Mrs Mallard takes to be a good mother to her brood, whereas in the research reported in the news story, which was done in Oxford University’s Zoology Department (of hideous aspect: see post for 12 June 2016), there was no mother duck: the experiment involved creating substitute mothers out of assorted coloured shapes. I shall make a 2-paragraph summary of it, which can be skipped (a more complete non-technical report, illustrated with a video, can be found at http://www.pbs.org/newshour/rundown/ducklings-make-way-abstract-thought-oxford-study-finds/).

Newly hatched ducklings (in common with chicks and other baby fowl that quit their nest straight away) have to learn very promptly to identify, and to go on recognizing, their mother. The phenomenon is termed ‘imprinting’. It might seem a very basic act of perception, to know one’s own mother and recognise her anew on each sighting, but imprinting is by no means infallible. These young birds will very readily imprint on anything which stands in for the mother at the crucial time. It’s possible, therefore, to take advantage of this pathetic gullibility in order to discover exactly what faculties of perception and cognition the baby birds are using. Certainly they must rely on such indications as colour and shape, but can they detect and use the more abstract properties in what they see? After all, the apparent colour and shape of the mother must vary with changing light and movement.

The abstract properties or relations which the Oxford research tested were sameness and difference. The newly-hatched mallard ducklings (154 of them) were each given time to imprint on a linked pair of coloured shapes – to call them ‘mother’, in short. They were then presented with two variations of these pairs, one of which preserved an essential relation from the first – sameness or difference of shape or of colour – and one of which did not. The ducklings did indeed seem to use these relations in order to fix upon the right or original ‘mother’. Very much needing a mother, they apparently searched for and found one even in such abstract qualities; or in case that sounds anthropomorphic, here’s how the research summarizes it: “For a duckling critically dependent on proximity to its mother and siblings, defining the attachment stimulus configuration as a library of sensory inputs and logical rules increases the likelihood that the mother and sibling group will be identified with high fidelity in spite of considerable variations in how they are perceived.” You see? Yet such a capacity for conceptualization has hitherto “only been demonstrated … in species with advanced intelligence”. In short, they’re smarter than you think, or used to think.

This phenomenon of imprinting has been a subject of study for many years. One of its pioneers was the ethologist Konrad Lorenz, who in the 1930s famously induced greylag goslings to fix upon him as their mother. In his popular and excellent book King Solomon’s Ring (first English publication 1952), he describes the same accomplishment with mallard ducklings, the species used in the Oxford research, although Lorenz’s ducklings seemed to demand vocal identification as well:

If I ceased for even the space of half a minute from my melodious “Quahg, gegegegeg, Quahg, gegegegeg”, the necks of the ducklings became longer and longer corresponding exactly to ‘long faces’ in human children – and did I then not immediately recommence quacking, the shrill weeping began anew. As soon as I was silent, they seemed to think that I had died, or perhaps that I loved them no more: cause enough for crying! [42]

This scene – Lorenz quacking and waddling along in a squatting posture (for the ducklings ‘lost’ him when he stood up) – is worlds and minds away from the blank cubicle with suspended geometrical shapes in which, each one alone, the Oxford ducklings made their decisions. Both have their strengths and weaknesses as science, no doubt.

The original German title of King Solomon’s Ring was Er Redete mit dem Vieh, dem Vogeln und den Fischen (he spoke with animals, birds and fish), for it was a legend about King Solomon king-solomons-ringthat he had a magic ring which gave him this communicative power. And much of Lorenz’s research, as well as his home life, was indeed conducted in that style: “It is only by living with animals”, he said, “that one can attain a real understanding of their ways” [147]. Of course he was often charged with imputing, to the animals, strictly human thoughts and emotions. He defended himself in this way:

You think I humanize the animal? … Believe me, I am not mistakenly assigning human properties to animals: on the contrary, I am showing you what an enormous amount of animal inheritance remains in man, to this day.” [152]

I mention this because the question  of “assigning human properties” is a controversial one in all research into animal minds. One academic psychologist, Jennifer Vonk, by way of comment on a study of reasoning power in crows, has summarized the two parties to the controversy thus: on the one side are those who too readily grant “abilities to animals that are interesting largely because they potentially break down the human-erected divide between humans and other animals”; on the other are those who insist on “Morgan’s canon” – that is, the rule pronounced at the turn of the twentieth century by the experimental psychologist Conway Lloyd Morgan, that animal behaviour ought never to be interpreted as showing a ‘higher’ human-like faculty, if it can be adequately explained by a faculty “which stands lower in the psychological scale”.

No doubt it’s a matter of emphasis rather than incompatibility: one side looking for Darwinian continuities, the other preferring strictly behaviourist interpretations. We could happily leave them to work out their differences in the specialist journals, except that there are ethical consequences involved. I notice, for instance, that one of Jennifer Vonk’s references for the Lloyd Morgan side is an article from the journal Behavioural Brain Research declaratively titled ‘Darwin’s mistake: explaining the discontinuity between human and non-human minds’. Included among its authors is Daniel J. Povinelli. This is the psychologist whose work with chimpanzees at the New Iberia Research Center (University of Louisiana) is indignantly dispraised by Steven Wise in his book Rattling the Cage (1999). The point which Wise makes against Povinelli is that he treated the chimpanzee mentality with such Lloyd Morganish scepticism (for instance, in the providing of a carelessly bleak physical and social environment for the animals to grow up in), that he had pre-stunted the minds which he then studied and found wanting.

Not that the more Darwinian perspective guarantees a raised status for animals. It’s noticeable that when research of this ‘smarter than you think’ kind gets into the more popular media, it at once becomes affected by the sort of quips and puns which count for merry sparkle in that world. In the case of birds, there’s many a play on ‘bird-brained’, ‘free-range thinkers’, and so on. (Even Dr Vonk gets caught up in it: her comment piece in Current Biology [vol.25.2, 19 Jan 2015] is facetiously titled ‘Corvid Cognition: something to crow about?’) Such jokes are harmless fun, no doubt, if they are fun, but they tag these animal stories as light relief. Essentially the jokes invite a speciesist smirk at our inferiors and their primitive efforts to be more like us. That scene with the ducklings in King Solomon’s Ring comes in a chapter headed ‘Laughing at Animals’. The book itself is very entertaining, but Lorenz won’t countenance laughter at animals: he calls it “deriding things which, to me, are holy” [39]. He tells the story of the ducklings, for instance, as a joke against his own undignified antics as a searcher for the truth, and not because it’s a good laugh to put babies through their paces: in that scene, after all, they know, and he’s only the tyro trying to know, what it is they want.

I needn’t say that the Oxford research is presented wholly seriously, and was indeed an ingenious piece of work, if hardly conclusive. It seems not to have required a licence under the Animals (Scientific Procedures) Act (ASPA), though as Lorenz’s experiment shows, imprinting on the wrong thing surely may involve “distress” of the sort which ASPA is meant to supervise. Anyway, the research did have the approval of its departmental ethics committee, and the ducklings were returned to the Oxford University Farm afterwards (with what mothering prospects there, we don’t know).

All the same, these imprinting experiments make one uneasy for good reason. It’s not just that experimental psychology, essentially the taking apart of behaviour, has often enough entailed taking apart the brain itself (just follow the subject of imprinting into the neuroscience journals). More largely, the theme itself is disquieting. Even Nature (if I may personify it for a moment) with all its frivolous indifference to individual welfare and its short way with weakness, seems to have made an exception in the case of the maternal bond. The mildest of animals is lent anomalous courage during motherhood so that she’ll protect her offspring with selfless bravado. Here, if nowhere else, Nature itself seems to call something in its bloody free-for-all “holy” (to use Lorenz’s word). Or at least we can say factually that it’s in this one bond that the strongest and most absolute passions in animal life – of attachment and of bereavement – are to be found.

And now see how this unique complex of love, fear, and defiance has fared in the laboratory. “Mothers are important, it is generally agreed … but just how important?” – so asked Professor P. L. Broadhurst, introducing animal studies to a new generation in his popular  work The Science of Animal Behaviour (1963). It’s an ominous question coming from an experimental psychologist. In this case, it was preliminary to commending the work of Professor Harry Harlow, the man who had recently set about answering the question, in his Wisconsin laboratory, by depriving baby rhesus monkeys of their real mothers, and tempting them with various inorganic and savagely inadequate alternatives. Harlow’s experiments, metaphorically taking a blunt surgical knife to the principle of motherhood, cast a shadow of real iniquity over the whole of animal research – so much so, that a formal repudiation of them ought to be a condition of getting a licence under ASPA. But especially they have tainted and dishonoured the experimental study of imprinting and all its allotropes. The steady and unapologetic continuation of such study is a reminder, if one needed it, that in bio-science some things may at different times be illegal, but nothing is sacred.

Incidentally, it seems that there was a habit of jocularity in Harlow’s lab. I just mention it.

How to Learn about Magpies

Another of those ‘They’re smarter than you think!’ stories appeared in the Times last week. In fact probably they appear every week, somewhere around page 15, reporting on new research thought charming or grotesque enough to engage the readership. This one was headed ‘Magpies show their caring, sharing side’. Apparently, biologists at the University of Vienna have discovered that azure-winged magpies (cyanopia cyanus) will make food available to their flock-fellows in routine acts of “unsolicited altruism”: a surprise, it seems, because until very recently “many researchers believed that this sort of selflessness was a uniquely human characteristic.” Yes, they would have believed that, of course. Who had ever supposed that scientists were merely unprejudiced students of nature?

The middle of a daily paper, with views in all directions of murders, wars, law-court wrangles over huge fortunes, poverty, acts of cruelty and scenes of deranged luxury, isn’t where one can best appreciate that comfortable old scientific belief in selflessness as a human speciality. Nor was this magpie research itself exactly a kindly and sympathetic attention to other ways of life. On the contrary, it was a calculated interference. The birds which showed their altruistic behaviour were not enjoying what the original report (in Biology Letters) so evocatively calls “naturalistic contexts” (= freedom). They are (or perhaps were, their after-careers not being specified) caged birds, and were performing in a drastically simplified and controlled version of flock-life. But indeed, the whole behaviourist tradition to which this research belongs is the theoretical equivalent of such experimental settings, a drastically simplified conception of animal life.

Putting aside whatever cruelty may be thought implicit in the technique of the experiment, the project can’t even be called dis-interested as science. The larger problem which this research – like other such research, on other species – claims to illuminate is “the evolution of human altruism”. As the author of the book featured in the previous post, The Science of Animal Behaviour, said in 1963 (perhaps the high noon of the behaviourist tradition), “there is essentially only one basic scientific interest in the study of animal behaviour and that is to learn more about man himself.” And the comprehensive world-view in which that assumption plays its part is this: that the whole astonishing many-million-years history of animal life is properly seen as a warm-up act for ourselves. Whereas really (if I’m to keep to this on-stage analogy), the brief but savagely destructive contribution made by humans to the show is probably best likened to the house-fire which destroys both the show and most of the venue.

Fortunately the behaviourist tradition in animal studies has for some time been challenged or at least complemented by ethology, the study of animals as far as possible in their “naturalistic contexts”. As its great pioneer Konrad Lorenz has shown, such studies may include everything from meticulous and self-effacing observation in the field to full human participation. In fact ethology, though newish as a tolerated science, has been a going concern over many centuries in the form of amateur natural history and, more generally, of human curiosity and affectionateness. For a brilliant and delightful instance of this longer tradition, and therefore as an Corvus.JPGoffset to the Vienna University research, I recommend Corvus: a Life with Birds by Esther Woolfson (Granta 2008).

One of the rescued birds whose life in the Woolfson household the book describes is a magpie (not of the azure-winged sub-species, though of course both are corvids). He was christened Spike, and being part-domesticated from earliest life he could never safely leave the house. You might therefore expect a series of anecdotes of cute and humanized behaviour. No: Spike’s stubborn otherness (I have to use that fashionable term here), and the strength of will through which his nature as a magpie expressed itself, are everywhere insistent. At the same time, qualities and conduct which we might carelessly regard, following our scientific mentors, as “uniquely human” – thought, empathy, practical joking, football games – this history of Spike compels us to believe we see fully translated in him. Pioneered, rather: magpies, after all, knew and enjoyed the world long before we arrived.

Scepticism about our assumptions, and about what we really can know, is not a monopoly of scientists. Esther Woolfson certainly has it, but she qualifies its mental austerity or aloofness with a generous and affectionate egalitarianism, participating in these other lives without speciesist reserve.

On the one hand, then, she doesn’t wish or guide her birds to behave humanly; she doesn’t yearningly impute human motives to them, or make humanity the measure of value (in this, she is more ‘scientific’ than the Vienna researchers). She says, “I don’t want birds to be other than they are.” And habitually she tempers or quizzes what, as a human, she sees and thinks. For example, when Spike takes a fervent part in family ball-games, she describes him “shouting with what seemed remarkably like joy” (my italics).

On the other hand, she is always moved to see how much there must be that Spike and the other birds do share with humans, in emotions and in conduct: “it makes me feel as if I live in an indivisible world, that my belief that we’re nearer in every respect than I could have imagined is correct, that we are, whatever we are, something of the same.” Those last nine words, with their intellectual modesty and life-hospitable “we”, bring together all that is best in science and in humanity.

No doubt the research done at Vienna will make a useful addition to a certain kind of knowledge of some bird-life. It may even do a little to counter our prejudices against magpies: the Times correspondent very properly thinks it should. But I would say that one can learn more about the life of magpies (to say nothing about their possibilities as individuals), and therefore about our true and proper relation to them, from such a book as Esther Woolfson’s than from all that can ever come from the world’s cages and laboratories.
