Wild Free and Happy Sample 04


[Note: This is the fourth sample from my rough draft of a far from finished new book, Wild Free & Happy.  I don’t plan on reviewing more books for a while.  My blog is home to reviews of 199 books, and you are very welcome to explore them.  The Search field on the right side will find words in the full contents of all rants and reviews, if you are interested in specific authors, titles, or subjects.] 
 

Orangutans

Our orangutan cousins in Sumatra spend about 90 percent of their time in the trees, where they are safe from hungry tigers.  Living in low density, often solitary, they enjoy a peaceful life, free from the emotional aggravation of living in an anxious crowd.  Of all the apes, they are the least noisy, usually silent.  They move through the trees at a leisurely pace, never in a hurry.  There is always something to eat in the rainforest.  On average, females give birth every eight years, a longer spacing than any other mammal.

Orangutans are very intelligent.  Researcher Biruté Mary Galdikas said, “I’ve had this feeling, ever since I was very young, that the tropical rainforest represents the original Garden of Eden.  Our ancestors left the garden, but orangutans never did.  They maintained a childlike innocence that humans lost a long, long time ago.”

Sadly, a mob of palm oil tycoons are furiously replacing the rainforest with palm plantations, mostly in Borneo and Sumatra.

Chimpanzees

Chimpanzees can grow to a standing height of 5.5 feet (1.7 m), weighing up to 130 pounds (60 kg).  Males are larger and more robust than females.  Chimps spend most of their time in the trees.  Because of their size, they are less speedy and graceful at leaping through the tree canopy, compared to smaller primates.  So, when they want to visit somewhere not close by, they go to the ground and knuckle walk.

Humans evolved for living on the ground, and are optimized for long distance running.  While chimps are smaller than humans, their arboreal lifestyle has made them far stronger.   One experiment found that the arm strength of male chimps is five times that of humans.  Big heavily muscled human wrestlers cannot hold a chimp still, even a young four year old. 

Frans de Waal warns that “Having a chimp in your home is like having a tiger in your home.”  When chimps feel threatened by a human, the human is in danger, and if he attempts to defend himself, the chimp will be even more brutal.  Outdoors, when humans appear to be harmlessly passing through, chimps generally ignore them.

Chimp bands are dominated by an alpha male, who is often backed up by one or more alpha wannabes.  From time to time, the alpha is challenged by lower status males, one of which will eventually dethrone the cocky king of the harem.  When the alpha is defeated, the new alpha often kills the infants of nursing females, so they will become fertile sooner, and produce offspring having his superior genes.  An alpha tends to be abrasive to everyone, to intimidate them, and assert his control.  When male strangers make an appearance, they are welcomed with teeth, fists, clubs, and stones.  In skirmishes to defend territory, chimps are sometimes beaten to death.

Bonobos

Bonobos and chimps live close to each other, but their rainforest habitats are separated by the Zaire River.  The two species have never met in the wild, because neither can swim.  They look a lot alike, and until 1929 were thought to be a single species.  Chimps far outnumber bonobos, and their territory is much larger.  Male bonobos can weigh up to 86 pounds (39 kg), and females up to 68 pounds (31 kg).

The bonobo culture is strikingly unusual for primates.  Their groups are matriarchal.  Males are second-class.  Females determine how food is shared, and they eat while the males wait.  Chimps have sex only when a female is fertile.  Bonobos have sex almost anytime, several times a day, with anyone interested, young or old, in every imaginable way.  Because of this, it’s impossible to know who your biological father was.  So, no youngsters are deliberately killed.

Bonobos are incredibly lucky.  They live in a habitat with abundant food, and no serious competitors in their ecological niche, an ideal situation that does not encourage competition.  Chimps live in leaner lands, and compete for food with gorillas and baboons.  They feel the squeeze of crowding, and they reduce this pressure by infanticide, and by killing or driving away competitors.

Primate Diets

The first primates evolved from small nocturnal insectivores that gobbled bugs during the dinosaur era.  Today, all primates are omnivores, consuming both plant and animal foods.  None are vegetarians, but gorillas are primarily leaf eaters (folivores).  Most primate species are mainly fruit eaters (frugivores).  Tropical forests typically provide a year round supply of fruit, so most primates live close to them.  Fruit is 75 percent of a chimp’s diet, and sugar is rapidly converted to energy.  It’s interesting that human babies have a preference for things that taste sweet, a relic of our tree dwelling days.

Protein is an essential nutrient for primates, and it is mainly acquired by consuming animal foods, and certain types of leaves.  The primary source of animal protein is insects.  When insects are abundant, they can provide up to 90 percent of a healthy primate’s diet.  Meat is a high quality source of protein, far superior to plant sources.  It takes less effort for our digestive systems to utilize the protein from meat.  Some primates are good at predation, killing small animals.  Some are scavengers, dining on the leftovers of carcasses abandoned by carnivores.

While plant foods are most of their diet, bonobos also eat caterpillars, earthworms, shrews, reptiles, bats, flying squirrels, and small forest antelopes (duikers).  Chimpanzees also eat insects, birds, eggs, monkeys, duikers, bushbucks, wild pigs, and carrion.  Baboons also eat insects, fish, shellfish, rodents, hares, birds, vervet monkeys, and duikers.  The orangutan diet includes more than 400 types of food, but it majors in ripe fruit.  They sometimes dine on invertebrates, like caterpillars and worms, and, on rare occasions, meat.  Gibbons feed mainly on fruit, but also consume leaves, insects, bird eggs, and sometimes young birds.

Hominins are unusual primates because some species learned how to kill and cook large animals.  This was made possible by their experiments in tool making, and the domestication of fire.  Unlike other primate lines, hominins are able to digest big servings of highly nutritious animal foods.  Shepard Krech noted that the diet of Native Americans could sometimes include six to twelve pounds (2.7 to 5.4 kg) of meat per day.  For employees of the Hudson Bay Company, the daily ration was seven to eight pounds of meat.  Of course, the diet of wild artic societies consisted almost entirely of animal foods.

The Bottom Line

Non-hominin primates did not make complex weapons, strive to exterminate predators, spread around the world, enslave other species, invent agriculture, explode in numbers, live in filth, and die by the millions from infectious diseases.  They did not wage war against infectious diseases, soar into extreme overshoot, load the atmosphere with crud, and blindside the planet’s climate.  Instead, they continue to inhabit a niche in their ecosystem, and live as they have for millions of years, without rocking the boat.  This is nature’s way.

Somewhere along the path, hominins began exploring new paths that eventually led them farther and farther from nature’s way, into dark and dangerous realms.  A growing number of the cool new tricks we discovered had uncool consequences, eventually triggering disturbances that not only rocked the boat, but rocked the planet.  Edward Abbey said, “Man is literally undoing the work of organic evolution.”  This is the opposite of intelligent.

The accelerating frenzy of half-clever experiments has catapulted human modes of living to places far outside of the time-proven design encoded by our genetic evolution (hardware).  The long parade of naughty booboos was the result of an impulsive adolescent fling with cultural evolution (software).  I don’t believe that our hardware is fatally flawed.  Our software is, without a doubt, a deadly threat to us, our descendants, and the entire family of life.

In the coming decades, our operating system is going to crash, again and again, because of its countless bugs.  Before long, our radicalized blind faith in utopian techno-fantasies will be thoroughly rubbished by the nightmares we created with good intentions.  As life as we know it melts down, even stupid people (hopefully) will come to reject our culture’s fantasies.  What should we do?  Any bright ideas out there?

The disintegration and abandonment of the failed culture will create a vacuum, an opening for new modes of being, which must be radically different, radically simpler, and ecologically wise.  Now is a good time to be contemplating how things got to be this way.  Now would be an excellent time for serious efforts to learn from our many mistakes.  Repeating the same mistakes, generation after generation, is so embarrassing for critters with big brains (blush!).

In the following chapters, I’ll sketch out my interpretation of the human saga, from the perspective of humans as animals — not the Crown of Creation.  Happy trails!

Wild Free and Happy Sample 03


[Note: This is the third sample from my rough draft of a far from finished new book, Wild Free & Happy.  I don’t plan on reviewing more books for a while.  My blog is home to reviews of 196 books, and you are very welcome to explore them.  The Search field on the right side will find words in the full contents of all rants and reviews, if you are interested in specific authors, titles, or subjects.] 

The Primate Clans

Primates include both apes (no tails) and monkeys (tails).  Over the eons, different primate species evolved in different ecosystems.  Each location had a different mix of climate, food resources, advantages, and dangers.  These variables encouraged unique evolutionary adaptations.  The adaptations that best increased the odds for survival were more likely to be passed on to the following generations.  Each ecosystem was also in a process of endless change, sometimes slow and gradual, and other times fast and extreme.  Over time, in response to change, primate evolution fine-tuned beneficial adaptations, and abandoned the duds.

Since Neanderthals disappeared from the stage, our closest living relatives are the chimps and bonobos, with whom we share up to 99 percent of our genes.  Next closest are gorillas, and in fourth place are orangutans.  The ancestors of all four relatives have inhabited tropical forests for millions years without trashing their ecosystems.  Mainstream culture teaches us that they are less intelligent than we are (an advantage?).  Unfortunately, evolution has not outfitted them with bulletproof hides to protect them from bushmeat hunters and crabby farmers.  They do not instinctively mob and exterminate loggers, miners, and developers.

Let’s take a peek at a few of our primate relatives.

Snow Monkeys

Japanese macaque (snow monkey) habitat ranges from sub-tropical to sub-arctic.  In their sub-arctic locations, temperatures can dip to -4°F (-20°C).  Snow might cover the ground for four months, in depths up to 10 feet (3 m).  As winter approaches, their summer fur grows and thickens into gorgeous insulated coats.  Bands sometimes take a pleasant soak in a hot spring, on a snowy winter day.  They have been observed at elevations as high as 10,433 feet (3,180 m).

During the summer, they build up body fat by feasting at the warm season buffet, which includes the fruit, seeds, nuts, the vegetation of 213 plant species, and the crops of crabby gun-toting farmers.  They also dine on fish, insects, and invertebrates.  In winter months, they survive on stored body fat, and rough foods like leaves and bark.  They huddle together to keep warm. 

Hominins (human ancestors) evolved for life in the tropics, where there was no need for warm fur.  When they migrated into non-tropical regions, life got dangerously chilly.  To survive in snow country, they needed warm clothing and shelters — technological crutches that require tedious time-consuming toil that was completely unnecessary in their natural habitat.  They did not gradually move out of warm lands, and let evolution perfectly fine tune them for cooler places.  They were already extremely unusual high-tech critters, with their thrusting spears and domesticated fire.  They impatiently bypassed evolution.  Oh-oh!

Baboons

When climate change shrank the forest and expanded the savannah, the ancestors of baboons evolved in a way that allowed them to spend much of their time on the ground.  Few of them now live in tropical forests, but all baboons have retained the physique for scampering up trees.  Baboons intelligently avoid wild predators by sleeping at the top of steep cliffs.  Sleeping in trees protects them from lions and hyenas, but not leopards.  In daylight hours, when many large carnivores are snoozing, baboons forage in groups, paying constant attention to reality.

Spending time on the ground increased their vulnerability to daytime predators.  Male baboons evolved big, strong bodies and large canine teeth.  When predators approach, male baboons form a point defense to obstruct a quick, easy, surprise kill.  While the males hold off the threat, the females and their offspring have a chance to escape.  Baboons did not fabricate weapons and hunt animals larger than they were but, on happy days, they could mob a leopard and disassemble it.  Readers who have killed adult leopards with their teeth and bare hands know that this can be very dangerous.

The ancestors of both baboons and humans moved onto the savannah, where they learned to survive as ground dwelling primates in a rough neighborhood that included lions, hyenas, leopards, cheetahs, and crocodiles.  Baboons demonstrate that primates can survive in a dangerous habitat without spears, fire, or complex language — and they can do this without causing irreparable ecosystem degradation.  With smaller brains, grunt communication, and sticks and stones, the baboons have brilliantly lived sustainably for millions of years.  They continue to enjoy a healthy, pleasant, and traditional wild life.  Thus, our ancestors were not forced to choose between tool addiction and extinction. 

Baboons have tails, so they are monkeys, not apes.  Paul Shepard noted that ground monkeys are “the most aggressively status-conscious creatures on Earth.”  High-ranking males have primary access to females and food.  The rank order in the hierarchy regularly changed.  So, to maintain or elevate your rank, it was important to brutally attack your inferiors at every opportunity.  Daily life was a state of heightened stress and anxiety.  Any minute you might be chased, pummeled, and bitten. 

Robert Sapolsky spent 30 years studying a troop of baboons.  Over time, he came to like a few of them, but he really disliked the troop, because they were exceptionally mean to each other, hour after hour, day after day.  He came to understand that hierarchy and competition can be a destructive force in a community, and this principle also applied to humans, many of whom are shattered by stress filled lives.

Gorillas

Gorillas evolved a different mode of sustainable living.  They never left the tropical forests, and their diet is primarily vegetarian.  They would have a hard time surviving outside of the forest.  Gorillas spend hours each day stuffing their faces at the salad bar.  They have evolved large guts in order to digest this bulky fibrous feast.  Insects provide the animal food in their diet.  In one study, 25 percent of gorilla poop samples contained bits of termites.

Males can be twice as heavy as females, growing up to 485 pounds (220 kg).  The big guys can’t climb trees, but smaller gorillas do.  Trees are a place to sleep, and to escape from predators.  They live in groups of 6 to 30 individuals, dominated by one or two silverback males.  Silverbacks are generally shy and relaxed, except when disturbed by uninvited humans or other gorillas.  The only predators they fear are humans.

Gibbons

There are about 20 species of gibbons, apes that inhabit the tropical forests of Southeast Asia.  Gibbons are primarily arboreal, and they live in small monogamous groups.  They can swing through the tree canopy with astonishing speed — up to 34 miles per hour (55 km/h).  Science calls this form of travel brachiation.  Today, physically fit humans still have a limited ability to brachiate.  As a schoolboy, I used to swing by my arms, from rung to rung, on the monkey bars at the playground. 

Members of most gibbon species range in size from 12 to 17 pounds (5.5 to 7.5 kg).  Because they are small, confronting large predators is not an option, so the males and females of most species are about the same size.  Smallness is an asset, enabling them to travel rapidly through the forest canopy.

The Inner Life of Animals



In his bestselling book, The Hidden Life of Trees, Peter Wohlleben revealed the fascinating magic and mystery of trees.  He spent his childhood close to nature, where he was fascinated by the family of life.  In his adult years, he has been a forest manager in Germany, continually striving to nurture the health of the land, and minimize harms.  He has spent much of his life outdoors.  Consequently, he has developed a perception of reality that is quite different from the herd.

In his new book, The Inner Life of Animals, he directs his attention to animal life, which is also little understood by mainstream society — the folks who spend most of their lives in climate controlled compartments.  For them, the natural world is often just a meaningless blur of scenery along the freeway, and wildlife sightings are mostly on glowing screens.  The new book is a pleasant voyage into a kinder and gentler mindset.  Readers are served a banquet of interesting ideas, mostly.

Wohlleben is a caring man who wishes that humans would cause far less damage and suffering in the world.  That’s his message.  At his home in the woods, he keeps goats, horses, rabbits, dogs, and chickens.  He apparently treats them with kindness until they drop dead from old age, or become terminally ill.  He confesses to drinking goat milk and making cheese, but says not a peep about meat (a touchy subject these days).  He detests factory farms, hunters, and industrial forest miners.

He has a deep appreciation for the coherence of wild ecosystems, and the remarkable relationships that coevolution has produced.  A primary focus of his book is to confront the cult of human supremacy.  Like patriarchy, and get-rich-quick fever, human supremacist beliefs intensify the madness of modern society.  The cult asserts that anything non-human is below us.  It’s perfectly OK to cram 20,000 chickens, shoulder to shoulder, inside a metal shed, without guilt or shame.  They are mindless machines that can feel no pain, organisms incapable of thoughts or feelings.

Supremacism has left a boot print on the English language.  Throughout the book, there are two categories of critters, “humans” and “animals,” implying that humans are not animals.  Of course, that’s not true.  Take off your clothes and look in a mirror, and you will see an animal that looks a lot like a chimp or bonobo, our closest living relatives.

In the mirror you will see a furless tropical primate that evolved an upright bipedal stance fine-tuned for long distance running.  This enabled us to survive via persistence hunting — chasing animals across the savannah for hours, until they collapsed from exhaustion.  Louis Liebenberg wrote about this.  Our ancestors have been hunters for several million years, long before we became Homo sapiens.  As every gardener knows, our bodies are poorly designed for gathering seeds, nuts, melons, and berries — too much bending and backaches.

Wohlleben hates hunting, which in its current form is “no longer appropriate.”  During the season, the woods are crowded with hunters, hiding close to bait piles, with high-powered rifles.  Bullets are whizzing all over the place, and up to 650,000 wild boars die every year.  Some animals are merely wounded, and suffer agonizing deaths.  He doesn’t describe what “appropriate” hunting would be.  Society has vigorously exterminated wild carnivores, whilst growing staggering amounts of boar food.  Is boar overpopulation appropriate?

Wohlleben owns a number of domesticated animals, and they spend their days in locations enclosed by electric fences.  They cannot go where they please, and the fences discourage the indigenous wild lynx from dining on his exotic invasive critters.  This disturbs him a bit.  “Nature didn’t intend for goats and horses to spend their whole lives as prisoners behind a fence.  Let’s not pretend: these animals would hightail it in a heartbeat if they could.”  (Did nature intend the existence of domesticated animals?)  The best he can do is treat them respectfully.

He lives in the twenty-first century, when many people own domesticated animals, a source of wealth and status.  For these folks, wild predators are evil.  Chickens are fox food, and foxes are demonic anti-capitalist anarchists.  Many also plant large fields of boar food, and get quite upset when boars come to enjoy their generous offering.  Some farmers surround their corn fields with electric fences to keep them out.  In the good old days, before domestication, nobody owned the large game and edible plants.  Nobody got upset when wild predators consumed wild herbivores, because nobody’s status was diminished.  In egalitarian societies, all people were equal, and status consciousness was totally inappropriate.

In The Others, Paul Shepard brilliantly described how important it is for all humans to spend their entire lives in healthy wild ecosystems, surrounded by many species of wild animals.  He also explained the many ugly consequences of capturing, confining, and domesticating “goofies” and “hooved locusts.”  Civilized primates are seriously deformed and traumatized by spending their lives in isolation from their wild relatives.

It’s easy to gobble a Big Mac when you have been taught that animals are like rutabagas, dumb organisms.  Now, we’re learning how sensitive and intelligent animals are.  To complicate matters, in his tree book, Wohlleben revealed that plants are also not dumb machines.  How can we feed ourselves in a morally acceptable manner?  Chimps and bonobos happily beat small animals to death, eat them raw, with no guilt at all.  A robin eating a worm is not evil.  We all feed one another.

Wohlleben is a fountain of stories.  Foxes lie down, tongues out, and play dead to attract hungry crows.  Goats move away from the herd when it’s time for them to die, because their corpse will attract predators.  Hives of bees with insufficient honey for the winter will attack weaker hives, kill defenders, and swipe their stash.  Swifts rarely stand on the ground, they sleep while soaring.  The book is loaded with hundreds of anecdotes like these.  I shall let you discover them on your own.

According to the human supremacist myths, animals do not have consciousness, self-awareness, or emotions.  They cannot feel pain, communicate, remember events, grieve, express gratitude, or recognize individual humans.  Today, the core of the controversy over animal intelligence is whether or not they are capable of thinking. 

Humans, of course, can think like crazy.  In our brains, the neocortex is the engine of self-awareness, consciousness, and thinking — and humans have the greatest neocortex of all.  Oddly, while most of the book is dedicated to challenging human supremacy, Wohlleben refers to our neocortex as the “crowning achievement of creation.”  Indeed, no other species is capable of experiencing so much cognitive dissonance.

Folks who understand environmental history and ecological sustainability, and have learned how to engage in critical thinking, can readily detect enormous flaws in the core myths of our culture.  The view from their mountaintop, far above the thick smog of dodgy beliefs, perceives that thinking is at least as much of a curse as a blessing.  We can live without glowing screens, but we can’t live in a toxic wasteland, with a hostile climate.  Supremacist myths trump common sense.  You can lead the herd to the pool of knowledge, but you can’t make them think.

“Mommy?”  “Yes, dear?”  “What is intelligence?”  “Sweetheart, intelligence is turning old growth forests into money, destabilizing the climate, acidifying the oceans, driving many species to extinction — and not caring.  Intelligence is speeding across the land in motorized wheelchairs, dumping trash on the moon, creating vast coastal dead zones, and developing miracle cures for the infectious and degenerative diseases that emerged with the birth of civilization.”  “Mommy?”  “Yes, dear?”  “I don’t want to be intelligent.  Can I be wild, free, and happy?”
