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!

Bonobo: The Forgotten Ape


In the family of life, humankind’s two closest living relatives are bonobos and chimpanzees, two apes with strikingly different approaches to living.  Ninety-eight percent of our DNA is the same as theirs.  These three intelligent cousins share a common ancestor that lived five to seven million years ago.  In his book, Bonobo: The Forgotten Ape, primatologist Frans de Waal does a superb job of comparing the three cousins, and the photos of Frans Lanting are fantastic.

In Africa, chimps far outnumber bonobos, and inhabit a larger territory.  The two never meet in the wild, because apes cannot swim, and the Zaire River keeps them apart.  Both reside in dense tropical rainforests, and both sleep in the trees.  They are similar in appearance, and it wasn’t until 1929 that scientists realized that bonobos and chimps were different species.

Bonobos are lucky to live in a dense and rugged rainforest that is difficult for humans to get to, explore, and destroy.  Researchers can spend many days thrashing around in the foliage, completely unaware that a group of bonobos is silently looking down at them from the thick canopy above.  Bonobos were not studied in the wild until the mid-1970s, and research was interrupted from 1994 to 2003, by a civil war that claimed three million lives.  Chimps, on the other hand, had been known and studied for a long time.

During the twentieth century, industrial warfare brutally exterminated millions of humans.  For some reason, it became trendy to perceive humans as inherently violent.  Chimps were seen in a similar light, because of their resemblance to industrial humans.  Once, when two chimp groups came into contact, researchers observed the brutal massacre of the weaker group.

De Waal offered this insight on male chimps:  “Their cooperative, action-packed existence resembles that of the human males who, in modern society, team up with other males in corporations within which they compete while collectively fighting other corporations.”

Chimps and civilized humans typically live in groups dominated by alpha males who actively subdue their rivals.  Females are second-class.  When an alpha male chimp reaches retirement age, and is clobbered by a vigorous young upstart, the new alpha often kills the old fellow’s young offspring, so their mothers can promptly begin producing offspring with his genes.  Because of this, females with young tend to go off and forage alone, avoiding contact with the bloody stud and his buddies.

Bonobos look a lot like chimps, but live very differently.  Bonobo groups are matriarchal, and 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.

The genitals of female bonobos become enormously swollen when they are receptive to sexual delights.  They are receptive almost half of the time, whilst being fertile for just a few days.  Non-reproductive sex is an excellent way to defuse conflicts, keep everyone relaxed, and have a pleasant day.  Because everyone has sex with everyone, paternity is impossible to determine.  Therefore, male bonobos do not kill infants, because any infant might be their offspring.

Hominids have taken a third path, the nuclear family.  Long ago, with the arrival of the chilly glacial era, the rainforests we evolved in came close to disappearing.  Our ancestors shifted outside the forest.  The nuclear family was an adaptation for surviving on the open savannah.  Hominid offspring benefitted when their mothers and fathers lived together and cooperated.  Tightly knit groups of aggressive hominids could successfully kill game and fend off predators.  The strongest, fiercest males were more likely to survive and reproduce, so natural selection favored these traits.

Promiscuity was discouraged, because males did not want to spend their lives raising a rival’s offspring.  Thus, the nuclear family reduced the reproductive freedom of females, via moral constraints.  Hominid societies have probably been male-dominated from the start.  Male control further increased with the shift to sedentary living, and the accumulation of property.  Males wanted their life savings to be inherited by their own offspring.  This led to an obsession with virginity and chastity, and the prickly patriarchal mindset.

Civilized societies have developed patriarchal cultures.  “With a few notable exceptions, such as spotted hyenas and the lemurs of Madagascar, male dominance is the standard mammalian pattern.”  Chimps follow this pattern but, to the great delight of feminists, the discovery of female-dominant bonobo society has presented a less macho alternative.  So, who are humans?  De Waal says that humans are in the middle, between the two poles — both aggressive and empathetic.

Why are chimps and bonobos so different?  Both have low birth rates, and nurse their young for four or five years.  Bonobos live in a habitat with abundant food, and no serious competitors in their ecological niche, an ideal situation.  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 competitors.  Infanticide is common in many species, including lions, prairie dogs, mice, chimps, and gorillas.

We live in an era of extinctions, and the numbers of chimps and bonobos are in sharp decline, as their human cousins relentlessly expand.  Diamond miners, loggers, bush meat hunters, and war refugees continue pushing into their habitat.

De Waal appeared in a fascinating documentary, The Last Great Ape.  It includes many scenes of bonobos living in the wild.  We see them enjoying a pleasant life — eating fruit, having sex, climbing trees, playing, having sex, grooming each other, nursing.  In one scene, viewers look down from a plane zooming over the jungle, and the narrator says, “This part of the forest is like a time capsule; bonobos may have existed here in much the same way for two million years.”  Wow!

Viewers see animals that look like our ancestors, live like our ancestors, and still inhabit the region where our species originated.  The bonobos have obviously remained far more stable over two million years than humans have, because they enjoy good luck and just enough intelligence to live well in their niche.  When I contemplate the era of my 62-year life, and the skyrocketing destruction caused by humankind, it breaks my heart — and mindlessly killing the planet doesn’t even make us happy.  Big brains do not guarantee long-term stability and ecological sustainability.

Patriarchal chimps have also succeeded in living for two million years, in the same region, in a stable manner.  While they rudely offend our humanist and feminist sensibilities, they have evolved a way of living that is thousand times less destructive than that of the humanists and feminists in our insane society.

This raises an embarrassing question.  Exactly how did we benefit from complex language, literacy, technology, domestication, agriculture, civilization, and industrialization?

The Baka Pygmies are our relatives who have lived in the African rainforest close to forever.  In this video (2 min), they make an incredibly joyful noise.  The aura they radiate is that of wild people with deep roots in their ancestral home.  Sadly, their teeth indicate that their diet has been civilized.

This video (5 min) includes beautiful portraits of Baka Pygmies, along with their music.  The faces of the children radiate a glowing sense of joy and contentment.
