How the Western diet has derailed our evolution
Moises Velesquez-Manoff writes: For the microbiologist Justin Sonnenburg, that career-defining moment — the discovery that changed the trajectory of his research, inspiring him to study how diet and native microbes shape our risk for disease — came from a village in the African hinterlands.
A group of Italian microbiologists had compared the intestinal microbes of young villagers in Burkina Faso with those of children in Florence, Italy. The villagers, who subsisted on a diet of mostly millet and sorghum, harbored far more microbial diversity than the Florentines, who ate a variant of the refined, Western diet. Where the Florentine microbial community was adapted to protein, fats, and simple sugars, the Burkina Faso microbiome was oriented toward degrading the complex plant carbohydrates we call fiber.
Scientists suspect our intestinal community of microbes, the human microbiota, calibrates our immune and metabolic function, and that its corruption or depletion can increase the risk of chronic diseases, ranging from asthma to obesity. One might think that if we coevolved with our microbes, they’d be more or less the same in healthy humans everywhere. But that’s not what the scientists observed. [Continue reading…]

Why we think the very first farmers were small groups with property rights
For 95% of the history of modern humans we were exclusively hunter gatherers. Then suddenly about 12,000 years ago, something happened that revolutionised the way humans lived and enabled the complex societies we have today: farming.
But what triggered this revolution? Understanding this is incredibly challenging – because this occurred so far in the past, there are many factors to consider. However, by simulating the past using a complex computational model, we found that the switch from foraging to farming most likely began with very small groups of people that were using the concept of property rights.
Farming: an unlikely choice
It may seem obvious why we switched from foraging to farming: it made it possible to stay in one place, feed larger populations, have greater food security and build increasingly complex societies, political structures, economies and technologies. However, these advantages took time to develop and our early farmer ancestors would not have seen these coming.
Indeed, archaeological research suggests that when farming began it was not a particularly attractive lifestyle. It involved more work, a decrease in the quality of nutrition and health, an increase in disease and infection, and greater challenges in defending resources. For a hunter-gatherer at the cusp of the “agricultural revolution”, a switch to farming wasn’t the obvious choice.

The strange persistence of first languages
Julie Sedivy writes: Like a household that welcomes a new child, a single mind can’t admit a new language without some impact on other languages already residing there. Languages can co-exist, but they tussle, as do siblings, over mental resources and attention. When a bilingual person tries to articulate a thought in one language, words and grammatical structures from the other language often clamor in the background, jostling for attention. The subconscious effort of suppressing this competition can slow the retrieval of words—and if the background language elbows its way to the forefront, the speaker may resort to code-switching, plunking down a word from one language into the sentence frame of another.
Meanwhile, the weaker language is more likely to become swamped; when resources are scarce, as they are during mental exhaustion, the disadvantaged language may become nearly impossible to summon. Over time, neglecting an earlier language makes it harder and harder for it to compete for access.
According to a 2004 survey conducted in the Los Angeles metropolitan area, fewer than half of people belonging to Generation 1.5 — immigrants who arrive before their teenage years — claimed to speak the language they were born into “very well.” A 2006 study of immigrant languages in Southern California forecast that even among Mexican Americans, the slowest group to assimilate within Southern California, new arrivals would live to hear only 5 out of every 100 of their great-grandchildren speak fluent Spanish.
When a childhood language decays, so does the ability to reach far back into your own private history. Language is memory’s receptacle. It has Proustian powers. Just as smells are known to trigger vivid memories of past experiences, language is so entangled with our experiences that inhabiting a specific language helps surface submerged events or interactions that are associated with it.

Music: New Jazz Frontiers — ‘Colibri’ (Edmar Castañeda)
The group, New Jazz Frontiers — Orlando “Maraca“ Valle (flute), Edmar Castañeda (harp), Ed Simon (piano), Luques Curtis (bass), Daniel Freedman (drums) — came together for the first time just two days before performing a collection of original compositions (by each of the band members) for the first time at Lincoln Center last December.
In a society where everyone is ready to defend the common good, corruption doesn’t pay
Suzanne Sadedin writes: By making a few alterations to the composition of the justice system, corrupt societies could be made to transition to a state called ‘righteousness’. In righteous societies, police were not a separate, elite order. They were everybody. When virtually all of society stood ready to defend the common good, corruption didn’t pay.
Among honeybees and several ant species, this seems to be the status quo: all the workers police one another, making corruption an unappealing choice. In fact, the study showed that even if power inequalities later re-appeared, corruption would not return. The righteous community was extraordinarily stable.
Not all societies could make the transition. But those that did would reap the benefits of true, lasting harmony. An early tribe that made the transition to righteousness might out-compete more corrupt rivals, allowing righteousness to spread throughout the species. Such tribal selection is uncommon among animals other than eusocial insects, but many researchers think it could have played a role in human evolution. Hunter-gatherer societies commonly tend toward egalitarianism, with social norms enforced by the whole group rather than any specially empowered individuals. [Continue reading…]
Music: Edmar Castaneda
Edmar Castaneda performs ‘Entre Cuerdas’ and ‘Jesus of Nazareth’ in an NPR Music Tiny Desk Concert.
“The Colombian plays the harp like hardly anyone else on earth. His hands, seemingly powered by two different people, produce a totally unique, symphonic fullness of sound, a rapid-fire of chords, balance of melodic figures and drive, served with euphoric Latin American rhythms, and the improvisatory freedom of a trained jazz musician…captivating virtuosity, but in no way only virtuosity for its own sake.” – Frankfurter Allgemeine Zeitung
“Mr. Castañeda strummed, plucked, rubbed, jabbed and pounded on his cobalt blue Llanera harp as he conjured different shaped notes, harmonic textures and steady bass rhythms from the instrument’s 34 strings. About the only thing he didn’t do was light it on fire.” – Wall St Journal
Edmar Castaneda was born in 1978, in the city of Bogotá, Colombia. Since his move to the United States in 1994, he has taken New York and the world stage by storm with his virtuosic command of the harp – revolutionizing the way audiences and critics alike consider the instrument. A master of beautifully complex timing, lush colors and dynamic spirit, Edmar has been called “almost a world unto himself” – The New York Times.
The legendary Paquito D’Rivera, Edmar’s frequent collaborator, describes him as “an enormous talent. With his versatility and enchanting charisma, he has taken his harp out of the shadows, and become one of the most original musicians in the Big Apple.”
How politics shaped general relativity
David Kaiser writes: The turmoil and disruptions of World War I … prevented many people from learning and thinking about general relativity. The theory’s earliest converts included a Russian mathematician being held in a German prisoner-of-war camp, who was unable to enlighten his Russian colleagues for several years; a German astronomer being held in a Russian prisoner-of-war camp, who was unable to complete his test of one of the theory’s key predictions; and another German astronomer, who passed the time while serving in the German Army by finding the first exact solutions to Einstein’s equations, only to succumb to a deadly disease on the Russian front a few weeks later.
The war also controlled how Einstein’s work spread westward. Because he was a German civil servant, neither Einstein nor his letters — nor even German scientific journals — could cross the English Channel amid the naval blockade. Einstein could, however, travel to neutral countries, like the Netherlands. He made frequent trips to Leiden, where he befriended the great mathematical physicist Willem de Sitter and tutored him in general relativity. And de Sitter, in turn, sent a series of detailed primers on Einstein’s work to a Cambridge colleague, the physicist and astronomer Arthur Eddington.
Eddington, a Quaker and conscientious objector, was concerned that wartime resentments were damaging the international scientific community. He leapt on Einstein’s relativity as a means of restoring harmony. As the historian Matthew Stanley has documented, Eddington’s superiors in London and Cambridge lobbied British government officials to let him devote his mandatory wartime service to preparing an astronomical expedition to test one of Einstein’s major predictions, that gravity could bend the path of starlight. By leading a British team to test the work of a German physicist, Eddington hoped to “heal the wounds of war.” [Continue reading…]

Linguistic diversity in the U.S: 320 languages spoken; 1 in 5 Americans don’t speak English at home
Quartz reports: Every year, the US Census Bureau releases data on the languages spoken in American homes. Usually it groups the languages in 39 major categories. Now it has released much more detailed figures, which show that Americans speak not 39, but more than 320 distinct languages.
The bureau collected the data from 2009 to 2013 as part of the American Community Survey, which asks Americans all kinds of questions to create highly granular estimates on various demographic indicators. The new data estimate that more than 60 million Americans speak a language other than English at home.
Included are 150 Native American languages, as well as relatively obscure ones like Pennsylvania Dutch, Icelandic, Mongolian, and many others. The data estimate that Sudanese, for example, is spoken at home by only 35 Americans. Patwin, spoken by a group of Americans native to northern California, it estimates at just four speakers.

There are some anomalies in the data presented here — such as the 12,320 speakers of “African.” That should say: African, not further specified.
