LOBSTERS—AND TERRITORY
Lobsters nervous systems are comparatively simple, with large, easily observable neurons, the magic cells of the brain. Because of this, scientists have been able to map the neural circuitry of lobsters very accurately. This has helped us understand the structure and function of the brain and behaviour of more complex animals, including human beings. Lobsters have more in common with you than you might think (particularly when you are feeling crabby—ha ha). Lobsters live on the ocean floor. They need a home base down there, a range within which they hunt for prey and scavenge around for stray edible bits and pieces of whatever rains down from the continual chaos of carnage and death far above. They want somewhere secure, where the hunting and the gathering is good. They want a home. This can present a problem, since there are many lobsters. What if two of them occupy the same territory, at the bottom of the ocean, at the same time, and both want to live there? What if there are hundreds of lobsters, all trying to make a living and raise a family, in the same crowded patch of sand and refuse?Other creatures have this problem, too.
When songbirds come north in the spring, for example, they engage in ferocious territorial disputes. The songs they sing, so peaceful and beautiful to human ears, are siren calls and cries of domination. A brilliantly musical bird is a small warrior proclaiming his sovereignty. Take the wren, for example, a small, feisty, insect-eating songbird common in North America. A newly arrived wren wants a sheltered place to build a nest, away from the wind and rain. He wants it close to food, and attractive to potential mates. He also wants to convince competitors for that space to keep their distance.Birds—and Territory
My dad and I designed a house for a wren family when I was ten years old. It looked like a Conestoga wagon, and had a front entrance about the size of a quarter. This made it a good house for wrens, who are tiny, and not so good for other, larger birds, who couldn’t get in. My elderly neighbour had a birdhouse, too, which we built for her at the same time, from an old rubber boot. It had an opening large enough for a bird the size of a robin. She was looking forward to the day it was occupied. A wren soon discovered our birdhouse, and made himself at home there. We could hear his lengthy, trilling song, repeated over and over, during the early spring. Once he’d built his nest in the covered wagon, however, our new avian tenant started carrying small sticks to our neighbour’s nearby boot. He packed it so full that no other bird, large or small, could possibly get in. Our neighbour was not pleased by this pre-emptive strike, but there was nothing to be done about it. “If we take it down,” said my dad, “clean it up, and put it back in the tree, the wren will just pack it full of sticks again.” Wrens are small, and they’re cute, but they’re merciless. My dad suggested that I sit on the back lawn, record the wren’s song, play it back, and watch what happened. So, I went out into the bright spring sunlight and taped a few minutes of the wren laying furious claim to his territory with song. Then I let him hear his own voice. That little bird, one-third the size of a sparrow, began to divebomb me and my cassette recorder, swooping back and forth, inches from the speaker. We saw a lot of that sort of behaviour, even in the absence of the tape recorder. If a larger bird ever dared to sit and rest in any of the trees near our birdhouse there was a good chance he would get knocked off his perch by a kamikaze wren.Despite being very different from each other, Wren and Lobsters have some things in common...
Both are obsessed with status and position, for example, like a great many creatures. The Norwegian zoologist and comparative psychologist Thorlief Schjelderup-Ebbe observed (back in 1921) that even common barnyard chickens establish a “pecking order.”Pecking Order
The determination of Who’s Who in the chicken world has important implications for each individual bird’s survival, particularly in times of scarcity. The birds that always have priority access to whatever food is sprinkled out in the yard in the morning are the celebrity chickens. After them come the second-stringers, the hangers-on and wannabes. Then the third-rate chickens have their turn, and so on, down to the bedraggled, partially-feathered and badly-pecked wretches who occupy the lowest, untouchable stratum of the chicken hierarchy. Chickens, like suburbanites, live communally. Songbirds, such as wrens, do not, but they still inhabit a dominance hierarchy. It’s just spread out over more territory. The wiliest, strongest, healthiest and most fortunate birds occupy prime territory, and defend it. Because of this, they are more likely to attract high-quality mates, and to hatch chicks who survive and thrive. Protection from wind, rain and predators, as well as easy access to superior food, makes for a much less stressed existence. Territory matters, and there is little difference between territorial rights and social status. It is often a matter of life and death.When the aristocracy catches a cold, as it is said, the working class dies of pneumonia.
If a contagious avian disease sweeps through a neighbourhood of well-stratified songbirds, it is the least dominant and most stressed birds, occupying the lowest rungs of the bird world, who are most likely to sicken and die. This is equally true of human neighbourhoods, when bird flu viruses and other illnesses sweep across the planet. The poor and stressed always die first, and in greater numbers. They are also much more susceptible to noninfectious diseases, such as cancer, diabetes and heart disease. Because territory matters, and because the best locales are always in short supply, territory-seeking among animals produces conflict. Conflict, in turn, produces another problem: how to win or lose without the disagreeing parties incurring too great a cost. This latter point is particularly important. Imagine that two birds engage in a squabble about a desirable nesting area. The interaction can easily degenerate into outright physical combat. Under such circumstances, one bird, usually the largest, will eventually win—but even the victor may be hurt by the fight. That means a third bird, an undamaged, canny bystander, can move in, opportunistically, and defeat the now-crippled victor. That is not at all a good deal for the first two birds.Conflict—and Territory
Over the millennia, animals who must co-habit with others in the same territories have in consequence learned many tricks to establish dominance, while risking the least amount of possible damage. A defeated wolf, for example, will roll over on its back, exposing its throat to the victor, who will not then deign to tear it out. The now-dominant wolf may still require a future hunting partner, after all, even one as pathetic as his now-defeated foe. Bearded dragons, remarkable social lizards, wave their front legs peaceably at one another to indicate their wish for continued social harmony. Dolphins produce specialized sound pulses while hunting and during other times of high excitement to reduce potential conflict among dominant and subordinate group members. Such behavior is endemic in the community of living things. Lobsters, scuttling around on the ocean floor, are no exception.5 If you catch a few dozen, and transport them to a new location, you can observe their status-forming rituals and techniques. Each lobster will first begin to explore the new territory, partly to map its details, and partly to find a good place for shelter. Lobsters learn a lot about where they live, and they remember what they learn. If you startle one near its nest, it will quickly zip back and hide there. If you startle it some distance away, however, it will immediately dart towards the nearest suitable shelter, previously identified and now remembered. A lobster needs a safe hiding place to rest, free from predators and the forces of nature. Furthermore, as lobsters grow, they moult, or shed their shells, which leaves them soft and vulnerable for extended periods of time. A burrow under a rock makes a good lobster home, particularly if it is located where shells and other detritus can be dragged into place to cover the entrance, once the lobster is snugly ensconced inside. However, there may be only a small number of high-quality shelters or hiding places in each new territory. They are scarce and valuable. Other lobsters continually seek them out.Dispute Resolution: Level 1
This means that lobsters often encounter one another when out exploring. Researchers have demonstrated that even a lobster raised in isolation knows what to do when such a thing happens.6 It has complex defensive and aggressive behaviours built right into its nervous system. It begins to dance around, like a boxer, opening and raising its claws, moving backward, forward, and side to side, mirroring its opponent, waving its opened claws back and forth. At the same time, it employs special jets under its eyes to direct streams of liquid at its opponent. The liquid spray contains a mix of chemicals that tell the other lobster about its size, sex, health, and mood. Sometimes one lobster can tell immediately from the display of claw size that it is much smaller than its opponent, and will back down without a fight. The chemical information exchanged in the spray can have the same effect, convincing a less healthy or less aggressive lobster to retreat. That’s dispute resolution Level 1.Dispute Resolution: Level 2
If the two lobsters are very close in size and apparent ability, however, or if the exchange of liquid has been insufficiently informative, they will proceed to dispute resolution Level 2. With antennae whipping madly and claws folded downward, one will advance, and the other retreat. Then the defender will advance, and the aggressor retreat. After a couple of rounds of this behaviour, the more nervous of the lobsters may feel that continuing is not in his best interest. He will flick his tail reflexively, dart backwards, and vanish, to try his luck elsewhere. If neither blinks, however, the lobsters move to Level 3, which involves genuine combat.Dispute Resolution: Level 3
This time, the now enraged lobsters come at each other viciously, with their claws extended, to grapple. Each tries to flip the other on its back. A successfully flipped lobster will conclude that its opponent is capable of inflicting serious damage. It generally gives up and leaves (although it harbours intense resentment and gossips endlessly about the victor behind its back). If neither can overturn the other—or if one will not quit despite being flipped—the lobsters move to Level 4.Dispute Resolution: Level 4
Level 4 resolution involves extreme risk, and is not something to be engaged in without forethought: one or both lobsters will emerge damaged from the ensuing fray, perhaps fatally. The animals advance on each other, with increasing speed. Their claws are open, so they can grab a leg, or antenna, or an eye-stalk, or anything else exposed and vulnerable. Once a body part has been successfully grabbed, the grabber will tail-flick backwards, sharply, with claw clamped firmly shut, and try to tear it off. Disputes that have escalated to this point typically create a clear winner and loser. The loser is unlikely to survive, particularly if he or she remains in the territory occupied by the winner, now a mortal enemy.Aftermath of a losing battle
In the aftermath of a losing battle, regardless of how aggressively a lobster has behaved, it becomes unwilling to fight further, even against another, previously defeated opponent. A vanquished competitor loses confidence, sometimes for days. Sometimes the defeat can have even more severe consequences. If a dominant lobster is badly defeated, its brain basically dissolves. Then it grows a new, subordinate’s brain—one more appropriate to its new, lowly position. Its original brain just isn’t sophisticated to manage the transformation from king to bottom dog without virtually complete dissolution and regrowth. Anyone who has experienced a painful transformation after a serious defeat in romance or career may feel some sense of kinship with the once successful crustacean.The Neurochemistry of Defeat and Victory
A lobster loser’s brain chemistry differs importantly from that of a lobster winner. This is reflected in their relative postures. Whether a lobster is confident or cringing depends on the ratio of two chemicals that modulate communication between lobster neurons: serotonin and octopamine. Winning increases the ratio of the former to the latter. A lobster with high levels of serotonin and low levels of octopamine is a cocky, strutting sort of shellfish, much less likely to back down when challenged. This is because serotonin helps regulate postural flexion. A flexed lobster extends its appendages so that it can look tall and dangerous, like Clint Eastwood in a spaghetti Western. When a lobster that has just lost a battle is exposed to serotonin, it will stretch itself out, advance even on former victors, and fight longer and harder. The drugs prescribed to depressed human beings, which are selective serotonin reuptake inhibitors, have much the same chemical and behavioural effect. In one of the more staggering demonstrations of the evolutionary continuity of life on Earth, Prozac even cheers up lobsters. High serotonin/low octopamine characterizes the victor. The opposite neurochemical configuration, a high ratio of octopamine to serotonin, produces a defeated-looking, scrunched-up, inhibited, drooping, skulking sort of lobster, very likely to hang around street corners, and to vanish at the first hint of trouble. Serotonin and octopamine also regulate the tail-flick reflex, which serves to propel a lobster rapidly backwards when it needs to escape. Less provocation is necessary to trigger that reflex in a defeated lobster. You can see an echo of that in the heightened startle reflex characteristic of the soldier or battered child with post-traumatic stress disorder.The Principle of Unequal Distribution
When a defeated lobster regains its courage and dares to fight again it is more likely to lose again than you would predict, statistically, from a tally of its previous fights. Its victorious opponent, on the other hand, is more likely to win. It’s winner-take-all in the lobster world, just as it is in human societies, where the top 1 percent have as much loot as the bottom 50 percent—and where the richest eighty-five people have as much as the bottom three and a half billion. That same brutal principle of unequal distribution applies outside the financial domain—indeed, anywhere that creative production is required. - The majority of scientific papers are published by a very small group of scientists. - A tiny proportion of musicians produces almost all the recorded commercial music. - Just a handful of authors sell all the books. A million and a half separately titled books sell each year in the US. However, only five hundred of these sell more than a hundred thousand copies. - Similarly, just four classical composers (Bach, Beethoven, Mozart, and Tchaikovsky) wrote almost all the music played by modern orchestras. Bach, for his part, composed so prolifically that it would take decades of work merely to handcopy his scores, yet only a small fraction of this prodigious output is commonly performed. - The same thing applies to the output of the other three members of this group of hyper-dominant composers: only a small fraction of their work is still widely played. Thus, a small fraction of the music composed by a small fraction of all the classical composers who have ever composed makes up almost all the classical music that the world knows and loves.Price’s law
This principle is sometimes known as Price’s law, after Derek J. de Solla Price, the researcher who discovered its application in science in 1963. It can be modelled using an approximately L-shaped graph, with number of people on the vertical axis, and productivity or resources on the horizontal.Pareto's Principle
The basic principle had been discovered much earlier. Vilfredo Pareto (1848–1923), an Italian polymath, noticed its applicability to wealth distribution in the early twentieth century, and it appears true for every society ever studied, regardless of governmental form. It also applies to the population of cities (a very small number have almost all the people), the mass of heavenly bodies (a very small number hoard all the matter), and the frequency of words in a language (90 percent of communication occurs using just 500 words), among many other things.The Matthew Principle
Sometimes it is known as the Matthew Principle (Matthew 25:29), derived from what might be the harshest statement ever attributed to Christ: “to those who have everything, more will be given; from those who have nothing, everything will be taken.” You truly know you are the Son of God when your dicta (winner-take-all) apply even to crustaceans. Back to the fractious shellfish: it doesn’t take that long before lobsters, testing each other out, learn who can be messed with and who should be given a wide berth—and once they have learned, the resultant hierarchy is exceedingly stable. All a victor needs to do, once he has won, is to wiggle his antennae in a threatening manner, and a previous opponent will vanish in a puff of sand before him. A weaker lobster will quit trying, accept his lowly status, and keep his legs attached to his body. The top lobster, by contrast— occupying the best shelter, getting some good rest, finishing a good meal— parades his dominance around his territory, rousting subordinate lobsters from their shelters at night, just to remind them who’s their daddy.All the Girls
The female lobsters (who also fight hard for territory during the explicitly maternal stages of their existence14) identify the top guy quickly, and become irresistibly attracted to him. This is brilliant strategy, in my estimation. It’s also one used by females of many different species, including humans. Instead of undertaking the computationally difficult task of identifying the best man, the females outsource the problem to the machine-like calculations of the dominance hierarchy. They let the males fight it out and peel their paramours from the top. This is very much what happens with stock-market pricing, where the value of any particular enterprise is determined through the competition of all. When the females are ready to shed their shells and soften up a bit, they become interested in mating. They start hanging around the dominant lobster’s pad, spraying attractive scents and aphrodisiacs towards him, trying to seduce him. His aggression has made him successful, so he’s likely to react in a dominant, irritable manner. Furthermore, he’s large, healthy and powerful. It’s no easy task to switch his attention from fighting to mating. (If properly charmed, however, he will change his behaviour towards the female. This is the lobster equivalent of Fifty Shades of Grey, the fastest-selling paperback of all time, and the eternal Beauty-and-the-Beast plot of archetypal romance. This is the pattern of behaviour continually represented in the sexually explicit literary fantasies that are as popular among women as provocative images of naked women are among men.) It should be pointed out, however, that sheer physical power is an unstable basis on which to found lasting dominance, as the Dutch primatologist Frans de Waal15 has taken pains to demonstrate. Among the chimp troupes he studied, males who were successful in the longer term had to buttress their physical prowess with more sophisticated attributes. Even the most brutal chimp despot can be taken down, after all, by two opponents, each threequarters as mean. In consequence, males who stay on top longer are those who form reciprocal coalitions with their lower-status compatriots, and who pay careful attention to the troupe’s females and their infants. The political ploy of baby-kissing is literally millions of years old. But lobsters are still comparatively primitive, so the bare plot elements of Beast and Beauty suffice for them. Once the Beast has been successfully charmed, the successful female (lobster) will disrobe, shedding her shell, making herself dangerously soft, vulnerable, and ready to mate. At the right moment, the male, now converted into a careful lover, deposits a packet of sperm into the appropriate receptacle. Afterward, the female hangs around, and hardens up for a couple of weeks (another phenomenon not entirely unknown among human beings). At her leisure, she returns to her own domicile, laden with fertilized eggs. At this point another female will attempt the same thing—and so on. The dominant male, with his upright and confident posture, not only gets the prime real estate and easiest access to the best hunting grounds. He also gets all the girls. It is exponentially more worthwhile to be successful, if you are a lobster, and male.Why is all this relevant?
For an amazing number of reasons, apart from those that are comically obvious. First, we know that lobsters have been around, in one form or another, for more than 350 million years.16 This is a very long time. Sixty-five million years ago, there were still dinosaurs. That is the unimaginably distant past to us. To the lobsters, however, dinosaurs were the nouveau riche, who appeared and disappeared in the flow of neareternal time. This means that dominance hierarchies have been an essentially permanent feature of the environment to which all complex life has adapted. A third of a billion years ago, brains and nervous systems were comparatively simple. Nonetheless, they already had the structure and neurochemistry necessary to process information about status and society. The importance of this fact can hardly be overstated.The Nature of Nature
The part of our brain that keeps track of our position in the dominance hierarchy is therefore exceptionally ancient and fundamental...
This brings us to an erroneous concept: that nature is something strictly segregated from the cultural constructs that have emerged within it. The order within the chaos and order of Being is all the more “natural” the longer it has lasted. This is because “nature” is “what selects,” and the longer a feature has existed the more time it has had to be selected—and to shape life. It does not matter whether that feature is physical and biological, or social and cultural. All that matters, from a Darwinian perspective, is permanence—and the dominance hierarchy, however social or cultural it might appear, has been around for some half a billion years. It’s permanent. It’s real. The dominance hierarchy is not capitalism. It’s not communism, either, for that matter. It’s not the military-industrial complex. It’s not the patriarchy—that disposable, malleable, arbitrary cultural artefact. It’s not even a human creation; not in the most profound sense. It is instead a neareternal aspect of the environment, and much of what is blamed on these more ephemeral manifestations is a consequence of its unchanging existence. We (the sovereign we, the we that has been around since the beginning of life) have lived in a dominance hierarchy for a long, long time. We were struggling for position before we had skin, or hands, or lungs, or bones. There is little more natural than culture. Dominance hierarchies are older than trees. The part of our brain that keeps track of our position in the dominance hierarchy is therefore exceptionally ancient and fundamental. It is a master control system, modulating our perceptions, values, emotions, thoughts and actions. It powerfully affects every aspect of our Being, conscious and unconscious alike. This is why, when we are defeated, we act very much like lobsters who have lost a fight. Our posture droops. We face the ground. We feel threatened, hurt, anxious and weak. If things do not improve, we become chronically depressed. Under such conditions, we can’t easily put up the kind of fight that life demands, and we become easy targets for harder-shelled bullies. And it is not only the behavioural and experiential similarities that are striking. Much of the basic neurochemistry is the same. Consider serotonin, the chemical that governs posture and escape in the lobster. Low-ranking lobsters produce comparatively low levels of serotonin. This is also true of low-ranking human beings (and those low levels decrease more with each defeat). Low serotonin means decreased confidence. Low serotonin means more response to stress and costlier physical preparedness for emergency—as anything whatsoever may happen, at any time, at the bottom of the dominance hierarchy (and rarely something good). Low serotonin means less happiness, more pain and anxiety, more illness, and a shorter lifespan—among humans, just as among crustaceans. Higher spots in the dominance hierarchy, and the higher serotonin levels typical of those who inhabit them, are characterized by less illness, misery and death, even when factors such as absolute income—or number of decaying food scraps—are held constant. The importance of this can hardly be overstated.Therefore, look for your inspiration to the victorious lobster, with its 350 million years of practical wisdom. Then you may be able to accept the terrible burden of the World, and find joy. And... Stand up straight, with your shoulders back.
