As with green chemistry and bio-mimicry, science is now discovering the depth of biological 251 ALTRUISM, GROUP IQ AND ADAPTATION Which have bigger brains, chimpanzees or baboons? If you guessed chimps, you’re right. Chimpanzees are our closest relatives on the planet. They share between 98.6% and 99% of our genes, depending on who’s counting. They are way up there in animal brainpower. An average chimp’s brain is more than twice as large as the brain of a baboon. Now for question number two. Which are smarter, chimpanzees or baboons? The answer is…baboons. But how could that be? Chimps are brainier. Shouldn’t they also be, well, umm, brainier? Brighter by far? If baboons are winners on IQ measures, doesn’t that mean that intelligence is not just a matter of brain matter? The answer is yes, there’s more to intellect than the number of neurons in your skull. So what’s the extra ingredient you need to turn brains into smarts? The answer is a bit surprising. Nimble minds need more than just a lot of synapses between brain cells. They need the power of groups. They need a force that pulses from the web of connection between group members…from the sum that’s bigger than its parts. They need what Gerardo Beni calls “swarm intelligence,” what Tom Atlee and Robert D. Steele call “Collective Intelligence” and what I call “Group IQ.”3 What in the world is Group IQ? For a hint, let’s look at the very first creatures to self-assemble on this planet. Let’s look at our oldest ancestors, the creatures who pioneered life on the early earth over 3.5 billion years ago, bacteria. A bacterial species that comes readily to mind is Eschericia coli. Eschericia coli is one of your most faithful companions. It lives in your gut and mine. It’s also a bacterial species microbiologists can’t keep their hands off of. It thrives in petri dishes and shows off its stuff in ways that are easy for a curious researcher with a good microscope to see. And, like baboons, E. coli are much, much smarter than most of us think. E coli are sugar junkies. Their favorite food is glucose. But when times get tough and the foods they like the most are nowhere to be found, they’ve got genetic tools they use to reengineer their string of genes, their genome, and their metabolism so they can eat far less tasty stuff, milk sugar—lactose. However there’s a substance E. coli have seldom come across in their long intelligence that human have yet to achieve. See Professor Ben-Jacob’s remarkable art gallery and substantive science at http://star.tau.ac.il/~eshel/gallery3.html. 3 “Social IQ” refers to an individual’s ability to interact with others, rather than the outcome of the collective engagement of many individual IQs in harmonization. 252 WHO’S SMARTER: CHIMPS, BABOONS, OR BACTERIA? history on this planet. It’s a chemical from the bark of poplars and willow trees. Its name is salicin. We use salicin as a pain killer. It’s the key ingredient in aspirin—a drug we didn’t begin to crank out in mass quantities until 1897. So in the 1980s and 1990s, several researchers decided to throw E. coli a curve. They gave colonies of these creatures nothing but salicin to eat. Now this is a bit like asking you and me to invent a new way to grow our gut and to retool the metabolic machinery of our cells so we can digest aluminum foil, gobbling it up like carrot cake, using it as our favorite food. Solving the salicin problem, the problem of turning salicin into an appetizer or an entrée, is a tough one. It involves a mutation, a big change, in your genome, a change that carries you forward a giant step but gets you essentially nowhere. Then it takes another big step with no payoff—rejiggering your genome in a way takes you backward—that makes you even LESS capable of eating and surviving than you were before. Only then can you take the big step forward in the reengineering of your gene-string that lets you eat salicin with ease. The odds against pulling off this big step forward, this big step back, and the final step forward again are huge. The odds against the trick are especially staggering if you think a bacterial colony is mindless and that it makes all of its changes using the genie-in-the-bottle of today’s mainstream evolutionary theory, Neo Darwinism. The Neo Darwinian magic mechanism for change and upgrade is random chance, random mutation. The odds of reengineering yourself to make salicin by random mutation alone—without a group brain— are ten billion trillion to one. Why? Because according to Neo Darwinian evolutionary theory, a big step backward like the one in the salicin two-step will kill your species off. Any bacteria who try it will be goners. They won’t live to reproduce and pass their new mutation on. So no way should a chain of mutations happen in which one step cripples something as basic as your ability to eat. Yet E. coli can reliably pull off the trick of reengineering their genes so they can eat salicin. How in the name of heaven or hell do they do it? The answer comes from one of my partners in crime, Eshel Ben Jacob, head of the Israeli Society of Physicists, former head of the Physics department at the University of Tel Aviv, and a man whose close to 20 years of breakthrough research in microbiology have landed in the queen of the science journals, 253 ALTRUISM, GROUP IQ AND ADAPTATION Nature, and on the cover of The Scientific American. Ben-Jacob is also kind enough to tolerate me. A colony of bacteria the size of the palm of your hand is populated by more citizens than all the human beings who have ever lived. The number of bacteria in that colony can vary from one to seven trillion. Each one of these trillions of bacteria has its own equivalent of a brain. It has what Ben Jacob calls a computational engine. That computational engine is its genome. Computer scientists discovered something interesting back in the 1980s. If you wanted to make a supercomputer for a lot less money than the ones that used to come at huge cost from the Cray Computer Company back in those ancient days, you had to abandon linear processing. You had to ditch the notion of threading all your information just one step at a time through one central microprocessor. You had to hook up a few dozen or a few hundred microprocessors and let them take their crack at the problem simultaneously. If you let your swarm of microprocessors operate in parallel, the “parallelprocessing” gizmo you produced was a supercomputer. And it cost one tenth the price of a Cray Computer…or less. Bacteria use the same trick. They use parallel distributed processing. And, frankly, so do you and I. We do it in our brains—communities of 100 billion nerve cells working on problems simultaneously. And we do it in our cultures—collective-thinking frameworks that pool our thoughts with those of our ancestors. But bacteria use parallel distributed processing in even more powerful ways than us human beings. Remember, there are over a trillion citizens, a trillion one-celled organisms, in a normal bacterial colony. Those bacterial cells spread out like members of a search party looking for a lost kid in a meadow. The object of their search? Territory rich in food. They talk to each other constantly, gossiping about their woes and their big scores, their discoveries of groceries, of enemies, of disasters, and of poisons. Their language of their chatter is chemical. They send out biochemical gradients of attraction and repulsion signals—chemical come-hithers and go-aways. When a high-priority problem hits, no single bacterium works on it by herself. The whole colony pitches in. That means between one trillion and roughly seven trillion microprocessors mull over a problem simultaneously. It also means that a trillion or more microprocessors spread out on the terrain are sending their reports in. 254 WHO’S SMARTER: CHIMPS, BABOONS, OR BACTERIA? Together, those trillion nano-processors make something utterly beyond the power of any single individual. They make something no single individual can even sum up or see. They generate what Eshel Ben-Jacob calls a creative web. They make a collective intellect capable of formulating problems, testing solutions and then, of all the amazing things, literally retooling, upgrading, and reinventing their own central string of genes—their own genome. Now that is collective smarts. That is collective intelligence. And it began 3.5 billion years ago when bacteria first evolved on this brand new planet earth. And I do mean that this earth was brand new when the first collective intellects emerged. This planet-in-the-making was still being smacked by comets and planetesimals. With each asteroid that thwomped it, the earth woggled like a pudding. And bacteria apparently outwitted the thwompings. The earth was a tricky and a challenging place when the first bacterial colonies got their group brains up and running. In other words, the earth was an intelligence tester par excellence. And bacteria passed the tests. The number of really big problems bacteria have solved since then is staggering. They’ve rejiggered their genomes so they can eat sulfur and rock. They’ve reengineered their genome so they can live two miles below the surface of the earth where the pressures are beyond belief and the food— granite—is on a par with driveway gravel. They’ve retooled themselves so they can live in a flood of radioactive particles that would kill off you and me. And there’s speculation that they’ve even learned to survive two miles above the ground in clouds and that they’ve learned to manipulate the weather so that the rains and sun give them the saunas and the food they love the most. What’s more, we’ve picked the brain of the bacterial mass mind more than we care to confess. We’ve stolen invention after invention from our singlecelled sisters. Our antibiotics are the weapons of mass destruction, the chemical weapons, with which two colonies of bacteria or more make war. Our genetic engineering kits are made of the tools bacteria use to reengineer their own genome. The tools behind our genetic engineering are plasmids, phages, and transposons. And we stole every one of them from the tool belt that bacteria wear. What’s more, our gherkin, herring, and sauerkraut processors recruit massive teams of bacteria to pickle food. Our cheese makers seduce vast armies of bacteria to make our cheese. And here’s something even more surprising. You use bacterial powers all the time. You are a collective intelligence of 100 trillion cells. As we’ve seen, a 255 ALTRUISM, GROUP IQ AND ADAPTATION hundred billion of those cells participate in the collective intelligence you think of as just one thing—your brain. But here’s a bigger surprise. Half of your hundred trillion cells don’t even claim to be you. They’re huge bacterial colonies living in your throat, your gut, and on your skin. Without them you’d be dead. In your pores bacteria turn what you exude into the sweet or sour smell that folks who’ve fallen in love with you have been attracted to…or that have made other folks edge away on those days when you’ve forgotten to use deodorant. More important, in your gut, bacterial colonies take things you can’t digest and finish the digestion process off for you. Their deal is that you feed them their favorite foods and they will munch them, they’ll shit out what they can’t digest, and their excrement will be on a par with honey and ambrosia to you. They’ll crap out the raw fuels that power you. What’s more, other bacterial colonies in your gut make your vitamin P, your vitamin K, and some of your B vitamins for you. Without your interior bacterial support team you couldn’t survive. To the bacteria inside of you, you are just a convenient self-guiding transport vehicle, a terrific food-gathering, and food-grinding machine. So next time you eat a chocolate éclair, remember there’s a lot of it that you can’t do much more than chew. You’re relying on bacterial teams to do the real digesting for you. I already mentioned that bacteria adapt to radioactivity. They’ve invented ways to thrive in the water pools used in nuclear reactors. Radioactivity periodically shatters their entire genome. Without a genome, you can’t survive. But these bacteria—the Deinococcus radiodurans —have built compression and storage systems that allow them to hold on to their critical data and reconstruct their genome over and over again. Now think about that for a second. That is the work of high IQ. That is research and development on a scale we can’t imagine. That’s the working of a collective intelligence and more, a collective innovation-and-breakthrough machine. OK, so I’m claiming there have been collective intellects since life began on this planet 3.85 billion years ago. This might easily make you wonder, if I’m so smart, and if all this is true, can we give group intellects an IQ test? The answer is yes. Here’s the proof: The ultimate test of intelligence is adaptability—how swiftly you can solve a complex problem, whether that problem is couched in words, in images, in crises, or in everyday life. The arena where intelligence is most important is not 256 WHO’S SMARTER: CHIMPS, BABOONS, OR BACTERIA? the testing room, it’s the real world. When you measure adaptability by the ability to turn disasters into opportunities and wastelands into paradises, bacteria score astonishingly high. But how do big-brained chimpanzees and small-brained baboons do? Or, to put it differently, how adaptable, clever, mentally agile, and able to solve real-world problems have chimpanzees and baboons proven to be? You can tell by the number of appeals made on TV, radio, and print made to save these primates’ tails. Jane Goodall has toured the world alerting us to a simple fact. The environment that allows chimps to live is rapidly disappearing. To save the chimps, we must save the environmental niche that gives them life. How many activists have you seen pleading with you to save the environment of baboons? None. Is there a reason? Yes. Baboons have been called “the rats of Africa.” No matter how badly you desecrate their environment, they find a way to take advantage of your outrage. One group, the Pumphouse Gang, was under study for years by primatologist Shirley Strum. When Strum began her baboon-watching, the Pumphouse Gang lived off the land in Kenya and ate a healthy, all-natural diet. They ate blossoms and fruits when those were in season. When there were no sweets and flowery treats, the baboons dug up roots and bulbs. Then came disaster—the meddling of man. Farmers took over parts of the baboons’ territory, plowed it, built houses, and put up electrified fences around their crops. Worse, the Kenyan military erected a base, put up homes for the officers’ wives and kids, and trashed even more of the baboons’ territory by setting aside former baboon-land for a giant garbage heap. If this had happened to a patch of forest inhabited by chimps, the chimpanzee tribes would have been devastated. But not the baboons. At first, the Pumphouse Gang maintained its old lifestyle and continued grubbing in the earth for its food. Then came a new generation of adolescents. Each generation of adolescent baboons produces a few curious, unconventional rebels. Normally a baboon trip splits up In small groups and goes off early in the day to find food. But one of the adolescent non-conformists of the Pump House Gang insisted on wandering by himself. His roaming took him to the military garbage dump. The baboon grasped a principle that chimps don’t seem to get. One man’s garbage is another primate’s gold. One man’s slush is another animal’s snow cone. 257 ALTRUISM, GROUP IQ AND ADAPTATION The baboon rebel found a way through the military garbage heap’s barbed wire fence, set foot in the trash heap, and tasted the throwaways. Pay dirt. He’d hit a concentrated source of nutrition. When they came back to their home base at the end of the day, the natural-living baboons, the ones who had stuck to their traditional food-gathering strategies, to their daily grind digging up tubers, came home dusty and bedraggled, worn out by their work. But the adolescent who invented garbage raiding came back energetic, rested, strong, and glorious. As the weeks and months went by, he seemed to grow in health and vigor. Other young adolescent males became curious. Some followed the nonconformist on his daily stroll into the unknown. And, lo, they too discovered the garbage dump and found it good. Eventually, the males who made the garbage dump their new food source began to sleep in their own group, separated from the conservative old timers. As they grew in physical strength and robustness, these Young Turks challenged the old males to fights. The youngsters’ food was superior and so was their physical power. They had a tendency to win their battles. Females attracted by this power wandered outside the ancestral troop and spent increasing amounts of time with the rebel males—who continued to increase their supply of high-quality food by inventing ways to open the door latches of the houses of the officers’ wives and taught themselves how to open kitchen cupboards and pantries and who also Invented ways to make their way through the electrified fences of farmers and gather armloads of corn. The health of the males and females in the garbage-picking group was so much better than that of the old troop that a female impregnated in the gang of garbage-pickers and farm-raiders was able to have a new infant every eighteen months. The females in the old, conservative, natural-diet group were stuck with a new infant only every 24 months. The innovators were not only humiliating the conservatives in pitch battles, they were outbreeding them. Why were the baboons so much smarter than chimpanzees? Why were they able to innovate and to surf the waves of change and the currents of the strange? Because they didn’t just think as individuals, they thought as a group. Their individualistic, curious adolescents were antennae, probing the possibilities of the unknown. These explorers and innovators sometimes went off on their own while the main troop broke up into small groups to do their wandering. But at night the small groups and individualists gathered to sleep together in crowds of from a hundred to seven hundred. And in the morning, through body-language 258 WHO’S SMARTER: CHIMPS, BABOONS, OR BACTERIA? arguments between the males about where to go during the day, these groups and rebels shared information, they compared notes. Chimps are not wanderers. They are stick-in-the-muds and stay at homes. They patrol their existing territory. And they live in groups of a mere fifteen to 35. They don’t get together in nightly multi-group conventions to compare notes. The result? When the old environmental slot of chimps wears out or is wiped away, they have no options, no fallback, or, more important, no fallforward positions. Baboons have smaller brains. But they have smarter Group IQs. And they can turn any environmental challenge you toss their way from disaster into opportunity. Chimps cannot. Here’s an additional guess about why the group IQ of baboons is higher than the group IQ of chimps. When chimps fission, when one group of chimps separates and becomes two groups, those two groups eventually replace peaceful competition with war. And I mean a war in which the losing group is exterminated…in which its adult males are murdered down to the last one and in which only the most delicious females, the fertile ones, are kept alive. When baboon groups fission, the groups compete with a far less genocidal form of violence. They have fights, brawls, gang bangs, and bullying sessions. They use their might and hurt each other. But they don’t wipe each other out. They don’t kill each other. They don’t pursue systematic genocide. The result is that the alternative strategies pursued by each baboon group— the alternative hypotheses—live on in the baboon mass mind. The bottom line? Baboons are on the increase in Africa. Chimps—despite their relatively humongous brains—are on the path to extinction. And that increase or shrinkage is a direct measure of adaptability, a measure of intelligence, a numerical indicator of group IQ. Another lesson, especially for the group of thinkers represented in this book—to have a high collective IQ, it’s not enough just to have a group and to parcel out the job of thinking in a nice, egalitarian manner. Structure makes all the difference in the world. Especially structure that uses individuals, small groups, and the collection of those groups into larger units, units that can share information. Structure that harvests the force of both competition and cooperation. Baboons have this sort 259 ALTRUISM, GROUP IQ AND ADAPTATION of competitive-cooperative-individualist-mall-group-plus-big-alliance structure. Chimps do not. And there’s another bottom line. Our social and psychological sciences have utterly ignored the study of collective intelligence, of Group IQ. Eshel Ben Jacob’s pioneering work on bacteria, for example, has appeared primarily in physics journals, not the journals that explore the secrets of the social body and of the psyche. And swarm intelligence has been largely relegated to the artificial intelligence, robotic, and computer communities. That’s a mistake. To raise our own Group IQ, it’s time for us humans to dig a little deeper and to study the inner secrets of social organization among our fellow organisms on this planet—bacteria, chimps and baboons. 260
