Darwin, Oversimplified

ChuckDCharles Darwin recognized early on the potential for people to oversimplify his writing. In particular, he was adamant that not everything in evolution was the result of adaptation by natural selection, though he worried that others would caricature his work in that way. In other words, Darwin was not as Darwinian as he is sometimes portrayed. The following passage comes from the sixth edition of On the Origin of Species (1872: 421):

 

 

“I have now recapitulated the facts and considerations which have thoroughly convinced me that species have been modified, during a long course of descent. This has been effected chiefly through the natural selection of numerous successive, slight, favourable variations; aided in an important manner by the inherited effects of the use and disuse of parts; and in an unimportant manner, that is in relation to adaptive structures, whether past or present, by the direct action of external conditions, and by variations which seem to us in our ignorance to arise spontaneously. It appears that I formerly underrated the frequency and value of these latter forms of variation, as leading to permanent modifications of structure independently of natural selection. But as my conclusions have lately been much misrepresented, and it has been stated that I attribute the modification of species exclusively to natural selection, I may be permitted to remark that in the first edition of this work, and subsequently, I placed in a most conspicuous position—namely, at the close of the Introduction—the following words: “I am convinced that natural selection has been the main but not the exclusive means of modification.” This has been of no avail. Great is the power of steady misrepresentation; but the history of science shows that fortunately this power does not long endure.”

The ‘Sapient’ Species

This Carl Sagan video “Pale Blue Dot” may not be new to many of you, but for those who haven’t seen it, I think everyone should watch it at least once. I’ve been thinking a lot lately about how frequently people conflict over personal issues, power, ideology, wealth, or for whatever rationale. What a way to use the finite time we have to exist. For a species that defines itself, taxonomically, as being sapient, we have an odd way of showing it. 

 

The Pale Blue Dot

“Consider again that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there–on a mote of dust suspended in a sunbeam.

Developmental Plasticity and the “Hard-Wired” Problem

“Development is the missing link between genotype and phenotype, a place too often occupied by metaphors in the past … But a strong emphasis on the genome means that environmental influence is systematically ignored. If you begin with DNA and view development as “hard-wired,” you overlook the flexible phenotype and the causes of its variation that are the mainsprings of adaptive evolution.” (Mary Jane West-Eberhard, 2003: 89-90)

“Genes, unlike gods, are conditional. They are exquisitely good at simple if-then logic: if in a certain environment, then develop in a certain way… So here is the first moral of the tale: Don’t be frightened of genes. They are not gods; they are cogs. (Matt Ridley, 2003: 250)

Plasticity: actor Christian Bale at two points in time. Same genes, different phenotypes.

In his book The Triple Helix, Richard Lewontin told the story of the molecular biologist and Nobel laureate Sydney Brenner, who – while speaking at a conference – predicted that one day we would be able to “compute” an organism (2002). All we would need are two things: the organism’s full genome and powerful enough computers that were up to the task.

The idea is seductive. Genes are sometimes seen as self-sufficient molecules, almost existing in a vacuum, that contain all the information necessary to code for proteins. From there, it’s not a very big logical leap to think that if you had the genome, you could enter the code in some database, hit “run,” and then watch some digitized version of the organism unfold.

In fact, scientists are doing something much like this for the tiny roundworm C. elegans with the project OpenWorm. Yet even for a relatively simple organism such as this, with only about a thousand cells in total, there are reasons to be cautious. As The Economist warned in its write-up of OpenWorm: “Attempting to simulate everything faithfully would bring even a supercomputer to its knees.” However, this isn’t due solely to the limits of computing power (what if we had a super-duper computer!?). Rather, it’s a matter of how the question is framed.

“I Am Only Human:” Malinowski & Integration

Bronislaw Malinowski, circa 1920. Source

For fun, I’ve been reading bits and pieces about the life of Bronislaw Malinowski, often described as one of the most important anthropologists of the early twentieth century for his contributions to ethnography. I’m not an ethnographer or a cultural anthropologist, but I stumbled across an essay by Michael Young about Malinowski’s life, as revealed by his own diary, which then led me to Young’s larger, book-length work (2004).

It is admittedly voyeuristic to look into the private thoughts of another person through their diaries. But it’s also a reminder about how complex we all are (some more so than others). For all his flaws, I find Malinowski to be a sympathetic figure. Maybe it’s because of his flaws. Young described him as “moody, irritable, sentimental, and melancholic” who made enemies as easily as friends. “But he could also be gregarious, emotionally generous, deeply courteous and scintillatingly eloquent. He was a demonically hard worker whose zeal galvanized those around him” (p. xxv). Again, he was complex.

The recurrent theme was that Malinowski was preoccupied with introspection in order to reform and improve himself. This seems rather commonplace, but his unique motivation was the desire to ‘integrate’ himself, by which he meant creating a coherent whole:

The Success of Nonviolence

I just came across the work on nonviolence by the University of Denver’s Erica Chenoweth. In this TED talk, she says that she began as a skeptic about the ability of nonviolence to make meaningful change. Someone challenged her to look into the topic further, and she says she was shocked by the results. I am too, in a good way.

“From 1900 to 2006, nonviolent campaigns worldwide were twice as likely to succeed outright as violent insurgencies. And there’s more. This trend has been increasing over time, so that in the last 50 years nonviolent campaigns are becoming increasingly successful and common.”

Below is the key figure from Chenoweth’s presentation, illustrating the percent of violent and nonviolent movements that succeeded in overthrowing a government or liberating a territory. It’s clear that nonviolent movements are not a panacea to reducing violence in the world. They aren’t always successful, and sometimes violent movements may be necessary.

Good Works in Laos

Manophet Rice Paddy

I never do this, but I’m asking people to check out a few sites that do good work related to Laos, and possibly consider donating to them.

The first, The Plain of Jars Project, was recently brought to my attention by its founder, Jon Witsell. This is borne directly out of the Lone Buffalo Foundation, named after Manophet Lonebuffalo, who I wrote about on this blog a couple of years ago after I learned that he had passed away from a stroke (and far too young). 

I met Manophet in the town of Phonsavanh in 2009 on a trip that was very meaningful to me. I only knew him for a few days, but he made an impression. I saw some of the good work he did with children and teenagers, teaching them English in his home and coaching football (soccer) in the field across the road. Those were his evening jobs. In the day, he also worked for the Japanese Mine Action Service, which helps remove the bombs that the US dropped on Laos during the war years. He was also an excellent tour guide and a single father of three boys.

He seemed to touch the hearts of many, and it’s no wonder that the people at The Plain of Jars Project would want to continue the good work he did. They have a fundraiser at startsomegood.com. The video below explains their goals, which include teaching boys and girls English, soccer, and awareness of avoiding unexploded ordnance (UXO).  Continue reading

An Amazing Thing

This is from Sasha Sagan, daughter of Ann Druyan and Carl  Sagan, remembering a time from her childhood when she began to understand mortality. Her parents told her: 

“You are alive right this second. That is an amazing thing,” they told me. When you consider the nearly infinite number of forks in the road that lead to any single person being born, they said, you must be grateful that you’re you at this very second. Think of the enormous number of potential alternate universes where, for example, your great-great-grandparents never meet and you never come to be. Moreover, you have the pleasure of living on a planet where you have evolved to breathe the air, drink the water, and love the warmth of the closest star. You’re connected to the generations through DNA — and, even farther back, to the universe, because every cell in your body was cooked in the hearts of stars. We are star stuff, my dad famously said, and he made me feel that way.

My parents taught me that even though it’s not forever — because it’s not forever — being alive is a profoundly beautiful thing for which each of us should feel deeply grateful. If we lived forever it would not be so amazing.”

Magical Origins of Love

People have come up with various ways to explain the origins of passionate love, including the scientific (we can find answers in our evolutionary past and  in our current biology, particularly the brain) or the mysterious (it’s ineffable, beyond comprehension). Others focus on the magical. The following passage comes from Bronislaw Malinowski’s classic ethnography of the Trobriand Islands, “The Sexual Lives of Savages” where he relayed the Trobriander view on the mythic origins of passionate love, as told by some of his informants, as well as his interpretation of the need for explanation (1929:539-44).

THE SOURCES OF LOVE MAGIC

Love, the power of attraction, the mysterious charm that comes forth from a woman to a man or from a man to a woman and produces the obsession of a single desire, is, as we know, attributed by the natives to one main source: the magic of love. 

In the Trobriands, most important systems of magic are founded on myth. The origin of man’s power over rain and wind; of his ability to control the fertility of the soil and the movements of fish; of the sorcerer’s destructive or healing powers — all these are traced back to certain primeval occurrences which, to the natives, account for man’s capacity to wield magic. Myth does not furnish an explanation in terms of logical or empirical causality. It moves in a special order of reality peculiar to dogmatic thought, and it contains rather a warrant of magical efficiency, a charter of its secret and traditional nature than an intellectual answer to the scientific why. The facts narrated in myth and the ideas which underlie it, colour and influence native belief and behaviour. The events of a remote past are re-lived in actual experience.This is especially important in the myth we are discussing, since its basic idea is that magic is so powerful that it can even break down the barrier of the strongest moral taboo. This influence of the past over the present is so strong that the myth generates its own replicas and is often used to excuse and explain certain otherwise inexcusable breaches of tribal law.

We have already spoken about the several systems of love magic, and pointed out that the two most important ones are associated with two local centres, Iwa and Kumilabwaga, which are united by a myth of the origin of their magic.

This is the story of the myth as I obtained it from informants of Kumilabwaga, the locality where the tragic events took place.

 

The story itself is fairly lengthy, but to summarize: long ago, a man made a potion of magical herbs, mint leaves, and coconut oil. He then hung the concoction in a vessel near the door of his family’s hut and left to bathe. His sister returned and accidentally brushed her head against the vessel, which allowed the potion to seep into her hair. She then smelled it, at which point “the power of magic struck her, it entered her inside, and turned her mind.” She then asked her mother where her brother was, found him, and removed her clothes, causing him to flee. Eventually, the magic overtook him as well, after which they copulated three times– in the water, on the beach, and in a nearby grotto. They then fell asleep, and died from shame and remorse for breaking the brother-sister incest taboo.

Malinowski wrote that there were several morals in the story. First, it was not a true origin myth. Rather, it was about how love had been transferred from one part of the islands (Kumilabwaga, where the brother and sister had lived) to another (Iwa). After the brother and sister had died, an Iwa man saw them in a dream, then paddled his canoe to their home and learned what happened from their mother, who –despite her grief– taught him the secrets of the magic, which he took home with him. Therefore, love’s origins had no true beginning. Instead, “most magic is imagined to have existed from the beginning of time, and to have been brought by each sub-clan from underground.” 

Second, Malinowski noted that in the story, the bulk of the blame for the siblings’ shame and ultimate death lay primarily at the feet of women, however unfairly. It was the mother who told her daughter to enter the hut in the first place to find some drinking water because she was too busy to pour some for her.  Malinowski compared the account to the biblical story of Eve giving the apple to Adam, or the legend of Isolde giving a love potion to Tristan: “in most mythological and legendary incidents, the man remains passive and the woman is the aggressor.” 

Finally, the magic of passionate love was powerful enough that it could overpower even one of the strongest taboos in Trobriand society. As Malinowski wrote, magic and myths from the past are “often used to excuse and explain certain otherwise inexcusable breaches of tribal law.” For those with a more scientific mode of thinking, they might remove the magical explanation and substitute it with hormones, neurotransmitters, or a specific brain region. Or, you could combine magical and scientific approaches: “I pull up to the front of your driveway, with magic soaking my spine.” Some of these are extrinsic to the individual, while others are intrinsic. What they have in common is that they fill a void in the search to explain agency and causality.

 

Acts of Reconciliation in Rwanda

“The world breaks everyone and afterward many are strong at the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry.”
                                                                                             – Ernest Hemingway, A Farewell to Arms

 

The New York Times Magazine published a photo essay of case studies of forgiveness and reconciliation in Rwanda, two decades after the genocide there. The photos show a Hutu perpetrator with his Tutsi victim, along with a brief description of their individual stories of violence and the long road to asking for forgiveness. In the above picture, the woman, Vivianne, says of her former perpetrator, Jean Pierre: Continue reading
