Why Are Bird Eggs Egg-Shaped? An Eggsplainer

Ed Yong in The Atlantic:

Lead_960 (5)When Mary Caswell Stoddard started measuring bird eggs from hundreds of species, she wasn’t expecting to learn that most eggs are not egg-shaped.

Think about an egg and you’ll probably conjure up an ellipse that’s slightly fatter at one end—the classic chicken egg. But chickens are outliers. Hummingbirds lay eggs that look like Tic Tacs, owls lay nigh-perfect spheres, and sandpipers lay almost conical eggs that end in a rounded point. After analyzing hundreds of species, Stoddard showed that the most common shape—exemplified by an unremarkable songbird called the graceful prinia—is more pointed than a chicken’s.

“We mapped egg shapes like astronomers map stars,” Stoddard says. “And our concept of an egg is on the periphery of egg shapes.”

Beyond displacing chickens as the Platonic ideal of egg-dom, Stoddard’s data also helped her to solve a mystery that scientists have debated for centuries: Why exactly are eggs shaped the way they are?

A Theory of Reality as More Than the Sum of Its Parts

Natalie Wolchover in Quanta Magazine:

ScreenHunter_2727 Jun. 24 22.50In his 1890 opus, The Principles of Psychology, William James invoked Romeo and Juliet to illustrate what makes conscious beings so different from the particles that make them up.

“Romeo wants Juliet as the filings want the magnet; and if no obstacles intervene he moves towards her by as straight a line as they,” James wrote. “But Romeo and Juliet, if a wall be built between them, do not remain idiotically pressing their faces against its opposite sides like the magnet and the filings. … Romeo soon finds a circuitous way, by scaling the wall or otherwise, of touching Juliet’s lips directly.”

Erik Hoel, a 29-year-old theoretical neuroscientist and writer, quoted the passage in a recent essay in which he laid out his new mathematical explanation of how consciousness and agency arise. The existence of agents — beings with intentions and goal-oriented behavior — has long seemed profoundly at odds with the reductionist assumption that all behavior arises from mechanistic interactions between particles. Agency doesn’t exist among the atoms, and so reductionism suggests agents don’t exist at all: that Romeo’s desires and psychological states are not the real causes of his actions, but merely approximate the unknowably complicated causes and effects between the atoms in his brain and surroundings.

Hoel’s theory, called “causal emergence,” roundly rejects this reductionist assumption.

“Causal emergence is a way of claiming that your agent description is really real,” said Hoel, a postdoctoral researcher at Columbia University who first proposed the idea with Larissa Albantakis and Giulio Tononi of the University of Wisconsin, Madison. “If you just say something like, ‘Oh, my atoms made me do it’ — well, that might not be true. And it might be provably not true.”

COMPASS BY MATHIAS ÉNARD

Compass-enardHal Hlavinka at the Quarterly Conversation:

Compass’s scope and erudition are astonishing—particularly when Énard drops any pretext of plot and shifts into a more essayistic voice—and the novel is simply riddled with barn burners. To wit: “[There] was graffiti here and there, I said anti-Semitism? He replied no, love”; “The terrifying nationalism of corpses”; “Music is time domesticated, reproducible time, time shaped”; “Tuberculars and syphilitics, there’s the history of art in Europe.” Said makes his own appearance as “the Great Name,” akin to “invoking the Devil in a Carmelite convent.” Like Mann, Énard balances his speaker’s arguments on an equilibrium between civilization (art, music, poetry, life) and chaos (war, greed, famine, death). We get an early glimpse of Ritter’s own theory of Orientalism through his musings on musicology. Figures like Beethoven and Liszt owe their innovations to the Romantic period’s fascination with the Orient’s alterity, smuggled into their art as a means of undermining “the dictatorship of church chant and harmony.” But the Orient’s influence on Western art isn’t direct; rather, artists are always caught in a tangle of influence upon influence, mistaken origins, smoke and mirrors, in a word, misrepresentations:

Berlioz never travelled to the Orient, but was, at the height of his twenty-five years, fascinated with Hugo’s Les Orientales. So there might be a secondOrient, that of Goethe or Hugo, of people who know neither Oriental languages, nor the countries where they are spoken, but who rely on the works of Orientalists and travellers like Hammer-Purgstall, and even a third Orient, a Third-Orient, that of Berlioz or Wagner, which feeds on these works that are themselves indirect.

It’s only fitting, then, that when Flaubert enters Cairo, he also enters the music of Beethoven—a Third-Orient of its own.

Essayism by Brian Dillon

Cwggetbze5bl5edsthosLauren Elkin at The Guardian:

Dillon suggests that we cannot define the essay, but that we might more productively gesture at some quality of essayism: a certain texture, a style, a voice, an “experiment in attention”. The essay will – and by its nature must – always resist attempts to pin it down. It refuses to be contained by any neat summary; it is “diverse and several – it teems”.

Dillon himself is a superbly varied essayist; the author of a range of books about photography, hypochondriacs, the great explosion at a munitions factory in Faversham, Kent, in 1916, and another written in 24 hours called I Am Sitting in a Room, his lines of inquiry are the body and its afflictions, contemporary art and literature, the history of place and ruins. He has a natural affinity for the essay “as a kind of conglomerate: an aggregate either of diverse materials or disparate ways of saying the same or similar things”. Lists are a wonderful tactic of essayism – consider Georges Perec’s astonishing lists in Species of Spaces, from the food and drink he consumed in 1974 to the objects on his desk. Dillon helps us see, via Joan Didion in The White Album, the list as incomplete, the very act of making a list a gesture at what cannot be listed or will always be left out: “the list, if it’s doing its job, always leaves something to be invented or recalled, something forgotten in the moment of its making”.

“Gaslight: Lantern Slides from the Nineteenth Century,” by Joachim Kalka

GaslightMichael Dirda at the Washington Post:

The biographical note accompanying “Gaslight: Lantern Slides From the Nineteenth Century” describes Joachim Kalka as “an essayist, literary critic, and translator of authors such as Martin Amis, Angela Carter, G.K. Chesterton, Christopher Isherwood, and Gilbert Sorrentino.” Impressive as it is, that list only hints at the extent of Kalka’s literary sophistication. His freewheeling essays — adroitly translated by Isabel Fargo Cole — reveal not only an easy familiarity with the obvious masterpieces of German, French and English-language literature, but also a devotee’s appreciation of ghost stories, mysteries, classic films and comics. His subjects range from Wagner’s conception of the Valkyries in “The Ring of the Nibelungs” to the artistic legacy of Jack the Ripper to a ­mini-history of anarchist bomb-throwing.

In fact, Kalka belongs to that admirable line of European intellectuals, such as Roland Barthes, E.M. Cioran, Umberto Eco and Simon Leys, who can write interestingly about almost anything. What he doesn’t do, however, is write conclusively. Whereas an American essayist frequently resembles a courtroom lawyer, trying to make an argument or prove a case, Kalka — who is from Stuttgart, Germany — is content to circle around a subject, illuminating it from various angles. Then, instead of closing with a knockout summary of the evidence, he simply stops. This can take getting used to. Still, how can you resist a writer who draws insights from “Mickey Mouse and His Sky Adventure” and Gershon Legman’s “Rationale of the Dirty Joke”?

Realization and Recognition: The Art and Life of John Fante

Neil Gordon in Boston Review:

John-FanteThe universe of John Fante’s fiction is so immediately moving, so poetically vivid, that it is hard to decide which is the greater quandary: that it went so long unrecognized, or that in the factitious worlds of publishing and Hollywood it is receiving such enormous recognition today. Fante was a writer from the 1930s, only occasionally recognized during his lifetime and swallowed, for long periods, by inactivity and obscurity. And yet today his complete works are in print with sales that any writer would envy: 100,000 copies of his books in America since 1980 and an astounding half-million copies in France. Most of his working life was spent in the subliterary world of Hollywood screenplays, and many of his novels never found a publisher. Yet he has now been accorded the highest commercial accolade: one book filmed and nearly every other one under option or in development, with Francis Ford Coppola and Robert Towne heading the impressive list of Hollywood figures who have invested serious money in his work.

Fante’s highly autobiographical fiction draws us deeply into his life, and that life reveals a struggle familiar to any reader of literary biography: between a profound urge to realize an artistic talent and an equally profound anxiety about recognition in the literary market. All writers struggle with the marketplace and many write about it, from Balzac to Hemingway. But the surprising turns of Fante’s commercial fortunes are rendered especially compelling by the sheer depth of his talent. His disturbing, singular writing stands absolutely alone among American Depression and mid-century writers. He was always the equal, and often the better, of his recognized contemporaries: Fitzgerald, Steinbeck, West, Schulberg. With no place in the genres of his day, it is only now that his finest work is being recognized as utterly original, and the precursor to voices of writers like Kerouac and Bukowski and through them, to a vast spectrum of contemporary writers.

Weekend Music Break No.110 — Abdullah Ibrahim’s ‘tawhid’

Samuel Argyle in Africaisacountry:

Ibrahim-piano-1024x682A shadow underlies many artistic expressions, including human spirituality and religion. In 1962, with Nelson Mandela imprisoned, the Cape Town-born Ibrahim left South Africa for Europe – where he met his mentor, Duke Ellington – and then on to New York to attend Juilliard. After struggling with alcohol and marijuana misuse and “searching for spiritual harmony in an increasingly fractured life,” Ibrahim returned to Cape Town. “Years of smoking and drinking had battered his body,” writes John Edwin Mason, a professor of African History at University of Virginia. “In New York, doctors and a Native American medicine woman both told him to ‘straighten up.’ And he did, entering a period of ‘cleaning’ and embarking on a spiritual quest that began in New York City and culminated with his conversion to Islam, in Cape Town.” Speaking about this turning point in his life with the UK Guardian in 2001, Ibrahim said, “I went back to church; I didn’t find it there. I went into all religions – the [Bhagavad] Gita, I-Ching. Then I realized most of the friends I grew up with were Muslim. Cape Town has a rare harmony, intermarriage.” The musician converted to Islam in 1968. During this period in the 1960s, harmony was sought after in America as well. Many American jazz musicians viewed Islam as part of a decolonization movement, as an escape from their country’s segregation laws. Before his conversion, Ibrahim was exposed to many musicians involved in the Muslim movement in America. Figures like Sheikh Daoud Faisal, a fellow alumnus of Juilliard, inspired up-and-coming jazz musicians like Ibrahim. Faisal lead a mosque in Brooklyn Heights and was a representative of Morocco at the United Nations. Archie Shepp, Ornette Coleman, John Coltrane, and Pharoah Sanders, to name a few, were also influenced by Islam, specifically Sufism and the Gnawa music of Morocco.

…While tawhid refers to the unity of God, it also maintains that the rest of the world is many. This paradox of oneness and multiplicity is central to Islam. It is also a major theme in Ibrahim’s music. Musicians perform in aggregate, forming an apparent whole. This dialectical relationship forming a captivating breathe of sound is only possible with someone as talented and devoted as Ibrahim guiding the movement. “The most beautiful, potent aspect of Islam is the unity of things,” Ibrahim told the Guardian. “You can’t throw anything out of the universe. This realization has been a driving force for me.”

Saturday Poem

How Things Work
Today it's going to cost us $20
To live. Five for softball. Four for a book,
A handful of ones for coffee and two sweet rolls,
Bus fare, Rosin for your mother's violin.
We’re completing our task. The tip I left
For the waitress filters down
Like rain, wetting the new roots of a child
Perhaps, a belligerent cat that won't let go
Of a balled sock until there is chicken to eat.
As far as I can tell, daughter, it works like this:
You buy bread from a grocery, a bag of apples
From a fruit stand, and what coins
Are passed on helps others by pencils, glue,
Tickets to a movie in which laughter
is thrown into their faces.
If we buy a goldfish, someone tries on a hat.
If we buy crayons, someone walks home with a broom.
A tip, a small purchase here and there,
And things just keep going. I guess. (Thanks Nils Peterson)

Does Anything Really Matter?: Essays on Parfit on Objectivity

Andrew Sepielli in Notre Dame Philosophical Reviews:

51nu++Cx+oL._SX328_BO1 204 203 200_This is a volume of essays on meta-ethical themes from Derek Parfit's magisterial book On What Matters. It boasts an impressive list of contributors, most of whom, we learn from Peter Singer's introduction, were chosen because Parfit saw fit to criticize their views at length. Predictably, then, most of them are established "big names", and many of their essays are defensive in character. As a result, the volume is a bit too intellectually conservative to meet the editor's stated goal of "reinvigorat[ing] discussions of objectivism in ethics". Nonetheless, it helps to clarify these discussions, and to bring out the deeper concerns that animated Parfit's bold and at times controversial stances in meta-ethics.

Several of the essays respond to Parfit's arguments against moral naturalism — in particular, his contention that if naturalism were true, moral claims could not state substantive truths. Now, we may agree with Parfit when it comes to crude versions of analytical naturalism, on which "is right", say, simply means "maximizes happiness". But Parfit means to target what he calls "non-analytical" naturalism as well, for he regards triviality as a metaphysical rather than a conceptual matter: no moral claim is substantive unless it ascribes an "irreducibly normative property". Since the naturalist does not believe in such properties, she must either say that moral claims are false (if, as Parfit suspects, they ascribe irreducibly normative properties), or non-substantive (if they don't).

A striking set of claims. Where do the contributors think it goes wrong? Peter Railton's essay is the one most squarely devoted to this question. He offers an alternative, naturalism-compatible account of substantivity.

How genetics is settling the Aryan migration debate

17THaryan migrationrevised-1

Tony Joseph in The Hindu:

The thorniest, most fought-over question in Indian history is slowly but surely getting answered: did Indo-European language speakers, who called themselves Aryans, stream into India sometime around 2,000 BC – 1,500 BC when the Indus Valley civilisation came to an end, bringing with them Sanskrit and a distinctive set of cultural practices? Genetic research based on an avalanche of new DNA evidence is making scientists around the world converge on an unambiguous answer: yes, they did.

This may come as a surprise to many — and a shock to some — because the dominant narrative in recent years has been that genetics research had thoroughly disproved the Aryan migration theory. This interpretation was always a bit of a stretch as anyone who read the nuanced scientific papers in the original knew. But now it has broken apart altogether under a flood of new data on Y-chromosomes (or chromosomes that are transmitted through the male parental line, from father to son).

Until recently, only data on mtDNA (or matrilineal DNA, transmitted only from mother to daughter) were available and that seemed to suggest there was little external infusion into the Indian gene pool over the last 12,500 years or so. New Y-DNA data has turned that conclusion upside down, with strong evidence of external infusion of genes into the Indian male lineage during the period in question.

A new book argues that thought and knowledge are community efforts

Gareth Cook in Scientific American:

ScreenHunter_2726 Jun. 23 17.29“The Thinker,” Auguste Rodin’s bronze sculpture, has become a visual cliché, a common representation of deep thought — a figure, gazing down, chin on hand, completely alone. This is utterly misleading, according to the authors of “The Knowledge Illusion,” which carries the subtitle: “Why We Never Think Alone.” Steven Sloman, a professor at Brown University, and Philip Fernbach, a professor at the University of Colorado’s Leeds School of Business, argue that our intelligence depends on the people and things that surround us, and to a degree we rarely recognize. Knowledge, they say, is a community effort. Sloman answered questions from Mind Matters editor Gareth Cook.

YOU ARGUE THAT WE DON’T KNOW AS MUCH AS WE THINK WE DO. CAN YOU EXPLAIN THIS?

People overestimate how well they understand how things work. Direct evidence for this comes from the psychological laboratory. The great Yale psychologist Frank Keil and his students first demonstrated the illusion of explanatory depth, what we call the knowledge illusion. He asked people how well they understand how everyday objects (zippers, toilets, ballpoint pens) work. On average, people felt they had a reasonable understanding (at the middle of a 7-point scale). Then Keil asked them to explain how they work. People failed miserably. For the most part, people just can’t articulate the mechanisms that drive even the simplest things. So when he again asked them to rate their understanding, their ratings were lower. By their own admission, the act of attempting to explain had pierced their illusion of understanding. We have replicated this basic finding many times, not only with everyday objects, but also with political policies. Matthew Fisher has shown that people overestimate their ability to construct logical justifications for their beliefs.

There’s nothing new about post-truth politics

Simon Blackburn in Prospect:

Unnamed (2)Here are three distinguished journalists, and three books on the same subject. Each one takes its title from the Oxford Dictionary’s word of the year for 2016, where “post-truth” was defined as an adjective “relating to or denoting circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.” Each is in part a response to the successes of the mendacious Donald Trump campaign and the disgraceful Brexit propaganda of the referendum. Each laments that social media and other dark arts of new technology have unprecedented power to manipulate and mislead a huge proportion of the population. The authors are to be congratulated on being among the first, although surely not the last, to ponder the meaning of the political disasters of 2016 and to worry about the climate that gave birth to them.

The similarity of the three books goes beyond their titles. Each realises that Trump and Brexit have economic and social causes, as swathes of the population, rightly believing themselves ignored and left behind by the Westminster bubble or Washington swamp, fell for the blandishments of simple, populist solutions. But it is not the economic and social causes of these upheavals that bother them. It is the danger that we are drowning in misinformation. We are all at sea, having no landmarks, no bearings, no ways of navigating the tides of spin, lies, bullshit and manipulations that assail us on every side. For every BBC there is a Fox News; for every reliable website there are dozens that peddle lies. So we need to reflect more and trust our “gut” less; we need to cultivate scepticism; we need fact-checkers, (or even fact-checker-checkers, and so on without end, for Quis custodiet ipsos custodes?); we need to find ways of publishing corrections far and wide, and so on.

All three authors are the kind of cocksure empiricists who have been embarrassed by the election result. Davis, an economist and a familiar face and voice from the BBC, shows the widest appreciation of the many ways in which people have always been economical, or worse, with the truth. He is thus slightly less panic-stricken about our present situation, and argues that above all we have to be tough on credulity.

THE RUBBLE OF BEIRUT

58ac09f1-2cef-43b2-bd60-e128666c7908Nathaniel Popkin at Public Books:

Lebanese author Elias Khoury’s latest novel to be translated into English, Broken Mirrors, is about identity and memory, destruction and displacement, exile and its internal ruptures. The book opens with the exiled Karim Shammas having just returned to a still-dangerous Beirut in 1990, as the Lebanese civil war that began in 1975 works its way to an explosive end. Karim suffers from a “homesickness for Beirut [that] had left him incapable of thought” and lands him in his home city without his knowing exactly why he is there. The deep, inexplicable longing that overtakes him in middle age is accompanied by paralyzing despair over endemic violence, endless war, and pervasive corruption. “The war will never end because it’s inside us,” says a woman, Salma, to Karim, reflecting not only the accumulated anguish of war, but the deeply fractured nature of Lebanon, Christian and Muslim, born from French and English imperial maneuvering and Maronite demands for a state independent of Syria at the fall of the Ottoman Empire.

Khoury, who was until recently a Global Distinguished Professor of the Middle Eastern and Arabic Studies at New York University and the editor of a top Lebanese literary magazine, Al-Mulhaq, is a stunning literary voice of Beirut’s despair and resilience. He isn’t alone in this project. Beirut, its sweep of sea and mountains perched on the edge of East and West, open and cosmopolitan, yet fundamentally unstable, has engendered an urban literature of resilience and memory, of voices trapped in the rubble.

the dead left

B35_Frost-SqAmber A'Lee Frost at The Baffler:

Marxist writer David Harvey notes that even Warren Buffett acknowledges the neoliberal era is marked by a one-sided class war, waged only by the capitalists. (“Sure there is class war, and it is my class, the rich, who are making it and we are winning,” Buffett has said.) The left lies sputtering on the mat, unable to maintain its ground, much less make any material gains. It’s hard to disagree when our gestures lack bite and our political parties—and most of our unions—are feckless at best, and capitalist quislings at worst. Whether it takes the form of insular campus activism, reactionary internet sermonizing, or impotent calls for general action, what passes for “the left” today is both parochial and completely disconnected from power. To put it bluntly, we have lost; we are decimated and we are feeble. What’s worse, we refuse to admit our failures, repeating them over and over and over again, castigating anyone who might question this pattern. In “Exiting the Vampire Castle,” Fisher alerted us to a “witch-hunting moralism”—in this case, against anyone who might try to raise class consciousness—that inevitably devolves into guilt and ineffectuality. In the wake of the election, it’s a lesson that seems to have gone largely unlearned by a self-sabotaging left.

A massive group exhibition at the Museum of Contemporary Art Detroit was basically drawn from junk, and so it remains

99_13-720x499Sarah Rose Sharp at Hyperallergic:

The show represents curatorial practice at its worst, and Hoffmann’s flawed conceits here are many. First, one senses, in talking to him, that prior to the moment he conceived of the exhibition, he had never before entered a dollar store. It seems to him to be a place of novelty and marvelous tackiness, of cheap manufacturing and purposelessness best viewed with ironic detachment. He described the scene to me as though I too had never been to a dollar store — let alone shopped at one — during a brief interview at MOCAD.

“[The show] was inspired by me going to a 99-cent shop in Brooklyn after doing a studio visit,” said Hoffmann, who is the senior curator at large at MOCAD, in addition to being the director of exhibitions and public programs at the Jewish Museum in New York. He was in search of a garment steamer, which of course the store didn’t have. “It was interesting, because they had so many things that were ethnically specific — I think it was a Vietnamese neighborhood — and then I started talking to other people that told me, in fact, most of the 99-cent shops are really geared toward the ethnic community that is around them.”

No kidding! It’s almost like dollar stores spring up in low-income communities, capitalizing on consumers who employ them not as ironic source material for art projects, but as the few places they can afford to shop for items that allow them to eke out a largely unsupported existence!

The Goat Fish and the Lover’s Knot

Sharon Harrigan in The Nervous Breakdown:

BookJack Driscoll is one of the most respected short story writers working today. He is not the most famous, but he is widely admired, especially among writers, as a craftsman whose work serves as a model for other writers to follow. The appeal is clear—his enormous compassion for his flawed characters; his gift for shining the spotlight on the kind of people and places that are so often overlooked both in literature and life; and his distinctive voice, which nimbly tightropes between high and low, vernacular and lyrical, comic and wise. His characters say things like “Christ on a bike” and “piss in one hand and wish in another and see which one fills first.” But their insights and vocabulary can also fly to great heights. “The idea of a million pilgrims desperate to put a knee down in this nothing town suddenly adjacent to God and heaven confounds even the dreamer in me,” says one of the book’s precociously eloquent adolescents.

In The Goat Fish and the Lover’s Knot, Driscoll’s big-hearted ability to make us love the troubled screw-ups he creates is on fine display. He finds the humanity in petty criminals, sarcastic teenage kleptomaniacs, and desperate divorcees. He makes us root for boys with names like Priest or Darwin or girls called Trinity or Novella—often living with one parent, while the other languishes in jail. Sometimes it’s the mother’s boyfriend or the protagonist who finds herself on the wrong side of the law, but the focus of the story is on their chances to claw themselves out of their “nowhere” lives, not repeat their parents’ mistakes, and find their better selves. They long to “shit-can” their “spirit-killing, grind-it-out jobs” or they dream of seeing the Himalayas. We feel their cramped circumstances and cheer them on as they sneak peeks of a bigger world beyond their “prefab repos” and double shifts at the Honcho or Twisted Antlers. Driscoll makes us care for the waitresses and warehouse workers, those scarred by fire or bad luck or made murderous by rejected small business loans, the mother who spends so much time in the water she is “part reptile,” the father who cut short his potential major league baseball career by accidentally guillotining his arm during a science project, or the former boxer scheming to rescue (or kidnap?) his ex-girlfriend’s son. His characters are so smart and reflective that we empathize with them, even when they’re engaged in fist fights, pot growing, or breaking and entering.

Ancient Egyptians may have given cats the personality to conquer the world

David Grimm in Science:

CatAround 1950 B.C.E., someone painted an unusual creature on the back wall of a limestone tomb some 250 kilometers south of Cairo. With its long front legs, upright tail, and triangular head staring down an approaching field rat, it is unmistakably a domestic cat—the first appearance in the art of ancient Egypt. In the centuries that followed, cats became a fixture of Egyptian paintings and sculptures, and were even immortalized as mummies, as they rose in status from rodent killer to pet to god. Historians took all this as evidence that the ancient Egyptians were the first to domesticate the feline. That is, until 2004, when researchers discovered a 9500-year-old cat buried with a human on the Mediterranean island of Cyprus, revealing that cats had been living with people thousands of years before Egypt even existed. A new study could put Egypt back in the limelight. A genetic analysis of more than 200 ancient cats suggests that, even if the animals were domesticated outside Egypt, it was the Egyptians who turned them into the lovable fur balls we know today. It’s even possible they domesticated cats a second time. “It’s a very nice piece of work,” says Salima Ikram, an expert on ancient Egyptian animals and cat mummies at American University in Cairo. The idea that the Egyptians helped shape the modern cat, she says, “makes perfect sense.”

…“The Egyptians were the first people to have the resources to do everything bigger and better,” says Carlos Driscoll, the World Wildlife Fund chair in conservation genetics at the Wildlife Institute of India in Dehradun, who led the 2007 study. That ability may have extended to breeding cats. As the Egyptians bred more and more felines, Driscoll speculates, they would have selected for the ones that were easiest to have around—more social and less territorial than their predecessors. “They turbocharged the tameness process.” Egypt’s art reflects this dramatic transformation. The earliest representations of cats depict a working animal, like the rat hunter in the limestone tomb. But over the centuries the felines begin to appear in more domestic contexts, hunting birds with people, wearing collars, and—by 1500 B.C.E.—sitting under chairs at the dinner table. “They go from being a slaughterer of mice to a couch potato,” says Eva Maria-Geigl, an evolutionary geneticist who oversaw the study with molecular biologist Thierry Grange, both at the Jacques Monod Institute in Paris.

A philosopher places creativity in evolutionary context

Marilyn Merritt in Science:

The-Evolution-of-Imagination-300x450The Evolution of Imagination, by philosopher Stephen Asma, is an ambitious and exciting book about creativity, rich with eclectic disciplinary references and enlivened with personal anecdotes. Charting new territory, Asma emphasizes the biological bases of imagination—sensory perception, emotions and affective systems, neurology, biochemistry, brain size and differentiation, and capabilities for motion and action—and casts these elements in evolutionary perspective.

One of Asma’s most striking claims is that imagination preceded human language. His main evidence for this assertion is that most biological requisites for imagination—including a limbic system to process affective states such as fear and attachment and sensory capability to recognize particular individuals—evolved in most social mammals, not only in primates.

Asma does not downplay the role of language in hominid evolution. Instead, he frames it as a powerful contributor to imagination and to the broader adaptive capability of improvisation—a type of performative creativity driven by intentionality and subject to real-time evaluation through feedback loops that monitor activity.

The book itself is a “jam session in six chapters,” each moving between occurrences of real-time improvisation and explanations of evolutionary origins, accounting for life span and species development, and individual expressive art, as well as group practices such as dance and storytelling.
