Claude Levi-Strauss dies at 100

I hope I live that long…no, really.

AP Story By Angela Doland

PARIS – Claude Levi-Strauss, widely considered the father of modern anthropology for work that included theories about commonalities between tribal and industrial societies, has died. He was 100.

The French intellectual was regarded as having reshaped the field of anthropology, introducing structuralism — concepts about common patterns of behavior and thought, especially myths, in a wide range of human societies. Defined as the search for the underlying patterns of thought in all forms of human activity, structuralism compared the formal relationships among elements in any given system.

During his six-decade career, Levi-Strauss authored literary and anthropological classics including “Tristes Tropiques” (1955), “The Savage Mind” (1963) and “The Raw and the Cooked” (1964).

Jean-Mathieu Pasqualini, chief of staff at the Academie Francaise, said an homage to Levi-Strauss was planned for Thursday, with members of the society — of which Levi-Strauss was a member — standing during a speech to honor his memory.

France reacted emotionally to Levi-Strauss’ weekend death, with French President Nicolas Sarkozy joining government officials, politicians and ordinary citizens populating blogs with heartfelt tributes.

Foreign Minister Bernard Kouchner praised his emphasis on a dialogue between cultures and said that France had lost a “visionary.” Sarkozy honored the “indefatigable humanist.”

Born on Nov. 28, 1908, in Brussels, Belgium, Levi-Strauss was the son of French parents of Jewish origin. He studied in Paris and went on to teach in Sao Paulo, Brazil, and conduct much of the research that led to his breakthrough books in the South American giant.

Beatriz Perrone Moises, an anthropology professor at the University of Sao Paulo, said “given his age, we were almost expecting this, but still I feel a kind of emptiness.”

“The Brazil he described in “Tristes Tropiques” is a very particular world of the senses and as he himself said there, it was a bit like rediscovering Americans, like the explorers of the 17th century. He often spoke about this emotion, this feeling. (For him,) Brazil that was less about the county itself than about the Brazil of the Indians and the feeling of walking in the footsteps of the 17th century explorers,” Perrone Moises told The Associated Press in a telephone interview from Sao Paulo.

Levi-Strauss left France during as a result of the anti-Jewish laws of the collaborationist Vichy regime and during World War II joined the Free French Forces.

Levi-Strauss also won worldwide acclaim and was awarded honorary doctorates at universities, including Harvard, Yale and Oxford, as well as universities in Sweden, Mexico and Canada.

A skilled handyman who believed in the virtues of manual labor and outdoor life, Levi-Strauss was also an ardent music-lover who once said he would have liked to have been a composer had he not become an ethnologist.

He was married three times and had two sons, Matthieu and Laurent.

Cultural evolution seen in polynesian canoes

Despite the popularity of cultural evolution as an idea, with cultures as organisms and memes as genes, the actual science has lagged.

But by applying the tools of population genetics to Polynesian boat designs, researchers show that cultural evolution might be studied as rigorously as the beaks of finches.

“Evolution is a logical way of looking at change over time,” said Deborah Rogers, a Stanford University evolutionary biologist. “There’s nothing inherently biological about it. The logic can be applied to cultural change. Biology was just the first place that people ran with it.”

Working with fellow Stanford researchers Marcus Feldman and Paul Ehrlich, Rogers converted archaeological records of Polynesian canoes, the design of which varied between islands and tribes, into standardized descriptions.

The structure of that dataset was described in a paper published last year in the Proceedings of the National Academy of Sciences. In the latest study, published in the November Proceedings of the Royal Society B, the researchers ran their data through a program of the sort typically used to analyze genetic information, inferring trees of relationships from patterns of inherited biological difference.

Multi-tasking in the stone-age

Stone blades found in Sibudu Cave, near South Africa’s Indian Ocean coast, bear traces of compound adhesives that once joined them to wooden hafts to make spears or arrows.

Why is this so cool? Because by systematically replicating the ancient glues, using only Stone Age techniques and ingredients, the researchers discovered that ocher improves the bonding capacity of such natural adhesives as acacia gum. They also learned that those ingredients are highly variable in chemical composition and thus in key characteristics, such as viscosity, that affect the strength of the bond.

To make an effective glue, say the researchers, ancient artisans would have had to adjust their recipes in real time to compensate for unpredictable ingredients, staying mindful of their goal while shifting their focus back and forth among the various steps in the process.

So maybe they were just mad scientists! Mwahahaha!

Gender in the brain

Scientific American recently published an article suggesting that boy brains and girl brains were not as biologically different as one might think.

Excerpt: “At first glance, studies of the brain seem to offer a way out of this age-old nature/nurture dilemma. Any difference in the structure or activation of male and female brains is indisputably biological. However, the assumption that such differences are also innate or “hardwired” is invalid, given all we’ve learned about the plasticity, or malleability of the brain. Simply put, experiences change our brains….

“…[For example] If the sex difference in the straight gyrus (SG) is present early in life, this strengthens the idea that it is innately programmed. Wood and Nopoulos therefore conducted a second study with colleague Vesna Murko, in which they measured the same frontal lobe areas in children between 7 and 17 years of age. But here the results were most unexpected: they found that the SG is actually larger in boys ! What’s more, the same test of interpersonal awareness showed that skill in this area correlated with smaller SG, not larger, as in adults.”

Here is Rafe‘s response to the article:

This article is terribly written, with ridiculous assumptions.

The first one – “On the other hand, sex differences that grow larger through childhood are likely shaped by social learning, a consequence of the very different lifestyle, culture and training that boys and girls experience in every human society.”

This is patently ridiculous. Virtually all sex differences grow larger with age as males and females diverge hormonally. Obviously we wouldn’t use culture to explain the accelerating gap in height and mass, or bone structure or secondary sex characteristics. Even gaps in things like aggression and neuroticism increase with age to peak in the early twenties before coming more in line with each other as we age beyond the 20’s.

Secondly, “Individuals’ gender traits—their preference for masculine or feminine clothes, careers, hobbies and interpersonal styles—are inevitably shaped more by rearing and experience than is their biological sex.”

This is just wishfull thinking. There is no experimental evidence to support this; essentially we are just talking about two sides of the same coin the masculinity or feminity of the body vs. the mind. Both are largely genetic, we just don’t fully understand all the mechanisms.

It pisses me off that they have to frame every story about this like somehow culture is the good guy riding in, that we can’t write it off, it might just save us from the big bad genetic bad guys after all. It’s editorializing and literally twisting the actually meaning of the study backwards, the important lesson of that study is yet another consistent and persistent cognitive difference between the sexes but they try to make it seem ok by implying it really all might be cultural.

Opining on the human brain

I found this really article interesting, http://www.slate.com/id/2223835/?GT1=38001

It’s a review about a book suggesting a cognitive theory on how baby’s brains process the world.

“Gopnik argues that babies are more conscious than adults. Her conclusion is based on the study of how attention and inhibition—the capacity to block out distractions—evolve over the course of development. Adult attention is willful and endogenous. Although it can be captured by external events—we will turn if we hear a loud noise—we also have control over what to think about and what to attend to. By sheer will, we can choose to focus on our left foot, then think about what we had for breakfast, then focus on … whatever we want. Adults are also blessed, to varying degrees, with the power to ignore distractions, both external and internal, and to stay focused on a single task.

“This is all harder for babies and young children. They are largely at the mercy of the environment. Simple experiments demonstrate that babies are, for the most part, trapped in the here and now, a conclusion supported by the finding that the part of the brain responsible for inhibition and control, the prefrontal cortex, is among the last to develop. Gopnik uses the example of an adult being dumped into the middle of a foreign city, knowing nothing about what’s going on, with no goals and plans, constantly turning to see new things, and struggling to make sense of it all. This is what it’s like to be a baby—only more so, since even the most stressed adult has countless ways of controlling attention: We can look forward to lunch, imagine how we would describe this trip to friends, and so on. The baby just is. It sounds exhausting, which might explain why infants spend so much of their time sleeping or (like some travelers) fussing.

“For Gopnik, this lack of inhibition and control is a gift. It makes babies and children ideally suited for the task of acquiring information about physical and social reality. When it comes to imagination and learning, their openness to experience makes them “superadults”—not just smart but smarter than we are. She’s particularly interested in the power to think about alternate realities, other possible worlds. In several fascinating chapters, she explores how this power is manifested in children’s play and in their creation of imaginary companions, plausibly arguing that the capacity to reason about worlds that do not exist is crucial to children’s rapid learning about everything from cause-and-effect relationships to human behavior. Gopnik suggests that their neural immaturity gives them greater imaginative powers than adults have: She proclaims, “Children are the R&D department of the human species—the blue-sky guys, the brainstormers. Adults are production and marketing. They [children] think up a million new ideas, mostly useless, and we take the three or four good one and make them real.”

It immediately made me jump to the idea that babies are innately ADHD.

I don’t want ADHD people to immediately jump on me and accuse me of calling them immature babies. First, I like the attitude that this brain perspective isn’t necessarily a bad thing. What I AM suggesting, as is Gopnik and LOTS of research on ADD brains, (sources available), is that the ADD brain is more primal, and that by understanding this we non-ADD people can help understand and appreciate ADD thought processes better, and maybe help tap into their gifts (wild and crazy problem-solving, for example).

Gopnik’s theory has faults (see page 2 of original article) but I still like the basic concept she’s getting at.

Just an interesting take on how humans develop.

Dyslexia and language

A cool post from Culture & Cognition about human language and how dyslexia differs between languages:

In a new paper Gabrieli highlight the recent results of cognitive neuroscience research on dyslexia and its potential consequences for the treatment of dyslexic children through educative measures.

What Gabrieli show is that dyslexia, an impairement in reading abilities linked to difficulties in phonological processing, can be detected very early on by brain imaging techniques and treated in some cases with specific training in reading during the beginning of learning. If left undetected and untreated, dyslexia can cause prolonged difficulties in reading abilities and decrease motivation to read.

Dyslexia and its orthographic consequences could be of great interest for cognition-and-culture oriented scientists because orthographic errors generated by dyslexia or other processes produce linguistic variation at the origin of language evolution.

Dyslexia, reaching around 10% of children, could therefore be an important factor of language evolution and may orient language evolution in different ways. If some words are more difficult to write and memorize for dyslexic children because the relation between their phonological form and their written form do not concord, dyslexic children may introduce new variants that are easier to learn for them.

Update on Baboon buddies

So my last post dealt with baboons making male/female relationships. The authors of the paper basically said because the dudes weren’t getting sex out of the females they didn’t see what the males were getting out of it. The females did get harassed less.

WELL, I just happened to be listening to an archived episode of Radiolab, probably a couple of years old, and they interviewed Robert Sapolsky, author of Why Zebras Don’t Get Ulcers and a studier of all things stressful. Sapolsky primary animal of study is baboons. In this interview, Sapolsky discussed this same phenomenon, where males will hang out with females, not for sex, just for companionship. Sapolsky actually seemed to imply that the males got more out of the relationships than the femmes. Why:

1. The males WERE in fact having sex more frequently with females in this troop of baboons.
2. When a dominant male gets old and loses his status, he is in essence drummed out of the troop, about half the time fleeing to a new troop where he is still lower on the totem pole but less harassed overall. HOWEVER, the half that don’t leave the troop are the ones who formed friendships with the females.

Ha ha! Having females as your allies is a political and evolutionary good idea for baboons. So it works out well for everyone involved.

There are probably different cultures of baboon troops, but it’s nice to know that at least for some male baboons it pays to have female friends.
