These bizarre ancient species are rewriting animal evolution

Traci Watson in Nature:

The revolutionary animal lived and died in the muck. In its final hours, it inched across the sea floor, leaving a track like a tyre print, and finally went still. Then geology set to work. Over the next half a billion years, sediment turned to stone, preserving the deathbed scene. The fossilized creature looks like a piece of frayed rope measuring just a few centimetres wide. But it was a trailblazer among living things. This was the earliest-known animal to show unequivocal evidence of two momentous innovations packaged together: the ability to roam the ocean floor, and a body built from segments. It was also among the oldest known to have clear front and back ends, and a left side that mirrored its right. Those same features are found today in animals from flies to flying foxes, from lobsters to lions.

Palaeontologist Shuhai Xiao marvels at the tracks left by this creature, Yilingia spiciformis, and how they captured evidence of its movement. In his cluttered office at Virginia Tech in Blacksburg, he shows off a slab of beige resin — a reproduction of the fossil, which was found in China’s Yangtze Gorges region and is now kept in a Chinese research institute. The replica captures a snapshot of a moment from 550 million years ago. Xiao, whose team formally described Yilingia last year1, traces the bumpy tracks it made immediately before its death. “It was just moving around, and it died suddenly,” he says.

Misremembering the British Empire

Maya Jasanoff in The New Yorker:

On a cloud-spackled Sunday last June, protesters in Bristol, England, gathered at a statue of Edward Colston, a seventeenth-century slave trader on whose watch more than eighty thousand Africans were trafficked across the Atlantic. “Pull it down!” the crowd chanted, as people yanked on a rope around the statue’s neck. A few tugs, and the figure clanged off its pedestal. A panel of its coat skirt cracked off to expose a hollow buttock as the demonstrators rolled the statue toward the harbor, a few hundred yards away, and then tipped it headlong into the water.

The Black Lives Matter movement has accelerated a reckoning across Europe about the legacies of slavery and imperialism, nowhere more urgently than in Britain, which presided over the largest empire in world history. The Colston statue stood on Colston Avenue, in the shadow of Colston Tower, on Colston Street, around the corner from Colston Hall. Scratch almost any institution with roots in Britain’s era of global dominance and you’ll draw imperial blood—from the Rhodes Trust, established by the fervent expansionist and white supremacist Cecil Rhodes, to the British Museum, whose founding collection was funded by profits from Jamaican plantations worked by slaves, and the Booker Prize, launched by a food company once notorious for its exploitative practices in the cane fields of British Guiana. Every year, the Queen honors hundreds of citizens with the Order of the British Empire. (A 2004 parliamentary committee recommended changing the name to the Order of British Excellence, to no avail.)

Public discussion in Britain about the imperial past has pivoted on a reductive question: Was the empire good or bad? The Labour Party has pledged to “ensure the historical injustices of colonialism, and the role of the British Empire” are “properly integrated into the National Curriculum,” while Boris Johnson, the Prime Minister, decries a “cringing embarrassment about our history.” A March, 2020, poll found that a third of Britons believed that their empire had done more good than harm for colonies—a higher percentage than in other former imperial powers, including France and Japan. More than a quarter of Britons want the empire back.

Asking, today, whether empire was good or bad is, as a historical matter, about as useful as asking whether the Atlantic Ocean is good or bad.

After George Steiner

Martin Jay at Salmagundi:

And yet, despite his shifting placement in the dynamic force field of cultural politics, Steiner resisted turning into a curmudgeonly apologist for a world on the wane or allowing his Kulturpessimismus to sanction a resentful withdrawal from the public arena. In fact, one of the hallmarks of his career was a willingness to remain suspended within paradoxes, never forcing a simple choice between unpalatable options. This attitude was already evident in Language and Silence, which both celebrates humanistic high culture and acknowledges that the Holocaust has disabused us of the naïve illusion that it humanizes those who uphold it. Or as he put it in what is perhaps his most frequently cited sentences: “We come after. We know now that a man can read Goethe or Rilke in the evening, that he can play Bach or Schubert, and go to his day’s work at Auschwitz in the morning.”17 And yet, Steiner somehow never really faltered in his faith that great art remains the last refuge of meaningfulness in a world from which religious faith has fled.

Thomas De Quincey’s Revelatory Writing

Jane Darcy at the TLS:

Thomas de Quincey by Sir John Watson-Gordon, c.1845

But to dismiss De Quincey as either a charming or a duplicitous figure on the margins of Romanticism is to ignore some of his most astonishing writing. He created a new kind of autobiography, constructed through resonant fragments grounded in dreams and reveries. Burwick describes him as “the first conscientious autobiographer of the interaction between conscious and subconscious experience”. He wrote eloquently on everything from political economy, psychology and Kantian philosophy to issues of literary style, but he could also sustain a highly inventive comic voice, notably in his satirical essays on violence. Robert Morrison, in this edition of Thomas De Quincey for the 21st-Century Oxford Authors series, presents an excellent selection for a new reader: Confessions and its sequel, Suspiria de Profundis, substantial extracts from his pleasingly waspish biographical essays from Recollections of the Lakes and Lake Poets and the great essays, including “On the Knocking at the Gate in Macbeth” and “On Murder Considered as One of the Fine Arts”. Morrison is an experienced De Quincey scholar, contributing to the The Works of Thomas De Quincey edited by Grevel Lindop (twenty-one volumes, 2000–3), editing the Oxford World’s Classics Confessions of an English Opium-Eater and Other Writings (2013) and writing a biography of De Quincey, The English Opium-Eater (2009). Because most of De Quincey’s writing appeared in journals, the task of sourcing his work has always posed editorial challenges. Added to this, De Quincey obsessively revised and rewrote his work, and his recovered manuscripts are often damaged and difficult to read. Morrison is a fine textual scholar, and in this edition includes interesting selections of manuscript material offering textual variants. Morrison’s extensive notes carefully explain matters such as De Quincey’s numerous Latin quotations (he was an exceptional, if somewhat tiresome, classicist), arcane vocabulary and new coinages.

The Agatha Christie Centennial: 100 Years Of “The Mysterious Affair At Styles”

J. Kingston Pierce in Crime Reads:

Agatha Christie was in her mid-20s when, in 1916, she took up what seemed the improbable endeavor of penning her first detective novel. It was so unlikely, in fact, that her elder sister, Madge, with whom she had always competed, dared Agatha to accomplish the feat, certain of her sibling’s eventual failure.

At the time, Christie was married to an officer in Britain’s Royal Flying Corps and working at a hospital in Torquay, England, first as a nurse and subsequently in the dispensary, preparing and providing medicines. It was in the latter job that she developed a fascination with poisons that would endure over the next six decades, supplying murderous means in many of her best-known books, including that very first one, The Mysterious Affair at Styles, which was published 100 years ago this month.

Styles was an early and influential contribution to what’s now called the Golden Age of detective fiction, a period that stretched arguably from the 1920s through the 1940s.

What Victorian-era seaweed pressings reveal about our changing seas

Laura Trethewey in The Guardian:

On his first day as the new science director for the Monterey Bay Aquarium in California in 2016, a giant blue storage locker caught Kyle Van Houtan’s eye. The locker was obscured by a dead ficus plant and looked as if no one had opened it for years. But the label on it intrigued him: Herbarium.

He opened it and inside found hundreds of stacked manila envelopes. Each one contained a single piece of seaweed, pressed and preserved on white paper.

The collection demonstrated a curator’s attention to detail, with neat labels in tidy handwriting that documented every seaweed’s origin and collector. And it gave Van Houtan and his colleague Emily Miller an idea.

The Party of Lincoln had a good run. Then came Mr. Trump.

The Editorial Board of the New York Times:

Senator John Cornyn of Texas, locked in his own tight re-election race, recently told the local media that he, too, has disagreed with Mr. Trump on numerous issues, including deficit spending, trade policy and his raiding of the defense budget. Mr. Cornyn said he opted to keep his opposition private rather than get into a public tiff with Mr. Trump “because, as I’ve observed, those usually don’t end too well.”

Profiles in courage these are not.

Mr. Trump’s corrosive influence on his party would fill a book. It hasin factfilled several, as well as a slew of articles, social media posts and op-eds, written by conservatives both heartbroken and incensed over what has become of their party.

But many of these disillusioned Republicans also acknowledge that their team has been descending into white grievance, revanchism and know-nothing populism for decades. Mr. Trump just greased the slide. “He is the logical conclusion of what the Republican Party has become in the last 50 or so years,” the longtime party strategist Stuart Stevens asserts in his new book, “It Was All a Lie.

Wednesday Poem

When the World Disappears

Driving through a flat-out prairie
blizzard is a classic struggle between
terror and faith. Between Paynton and
the Battlefords the world disappears
horizon, buildings, trees, traffic,
the road itself, all gone. Snow,
blasted by a fierce south-easter,
obliterates equally land and sky.

On this two-way stretch of highway
we drive into the snow cloud.
As vehicles behind and in front
vanish from my sight, so too have I
from them, my hands iron vises
clinging to the steering wheel,
clinging to frail threads of reason,
clinging to little more than blind hope
as the white-out erodes confidence
and panic probes below
the thin skin of logic.

We hurtle through nothingness,
my silent prayer willing that whatever
lies on the other side of this void,
whatever other drivers are steering
the margins of their own misery,
their paths do not intersect mine.
We are, all of us, blind pilgrims
groping for some distant shrine
lost from our view, alive only
in the minds that will them.

Can lab-grown brains become conscious?

Sara Reardon in Nature:

In Alysson Muotri’s laboratory, hundreds of miniature human brains, the size of sesame seeds, float in Petri dishes, sparking with electrical activity. These tiny structures, known as brain organoids, are grown from human stem cells and have become a familiar fixture in many labs that study the properties of the brain. Muotri, a neuroscientist at the University of California, San Diego (UCSD), has found some unusual ways to deploy his. He has connected organoids to walking robots, modified their genomes with Neanderthal genes, launched them into orbit aboard the International Space Station, and used them as models to develop more human-like artificial-intelligence systems. Like many scientists, Muotri has temporarily pivoted to studying COVID-19, using brain organoids to test how drugs perform against the SARS-CoV-2 coronavirus.

But one experiment has drawn more scrutiny than the others. In August 2019, Muotri’s group published a paper in Cell Stem Cell reporting the creation of human brain organoids that produced coordinated waves of activity, resembling those seen in premature babies1. The waves continued for months before the team shut the experiment down. This type of brain-wide, coordinated electrical activity is one of the properties of a conscious brain. The team’s finding led ethicists and scientists to raise a host of moral and philosophical questions about whether organoids should be allowed to reach this level of advanced development, whether ‘conscious’ organoids might be entitled to special treatment and rights not afforded to other clumps of cells and the possibility that consciousness could be created from scratch.

Bruce Nauman at The Tate Modern

Waldemar Januszczak at Waldemar Januszczak:

Back on planet Earth, in the show itself there is no limitless space-time, just a succession of powerful slabs of Nauman in which he swaps techniques, changes methods, explores materials, alternates moments of peace with bouts of heavy slapping, and never lets up in a madcap journey of artistic exploration usually set in darkness.

“My work comes out of being frustrated about the human condition,” he explained in 1988. “And about how people refuse to understand other people.” Fretful minimalism for the midnight hour?

What is immediately tangible is how influential he has been. It’s most obvious in the neon pieces that stud the show. Nauman started working with neon in 1965, using it to make a slippery word-art that keeps switching meanings. EAT, says a green neon sign, before changing to blue and saying DEATH.

Yeast study yields insights into longstanding evolution debate

From Phys.Org:

In the past two decades, researchers have shown that biological traits in both species and individual cells can be shaped by the environment and inherited even without gene mutations, an outcome that contradicts one of the classical interpretations of Darwinian theory. But exactly how these epigenetic, or non-genetic, traits are inherited has been unclear. Now, in a study published Oct. 27 in the journal Cell Reports, Yale scientists show how epigenetic mechanisms contribute in real time to the evolution of a gene network in yeast. Specifically, through multiple generations yeast cells were found to pass on changes in gene activity induced by researchers. The finding helps shed light on a longstanding question in evolutionary biology; scientists have long debated whether organisms can pass on traits acquired during a lifetime.

“Do genetic mutations have to be the sole facilitator of gene network evolution or can epigenetic mechanisms also lead to stable and heritable gene expression states maintained generation after generation?” asked Yale’s Murat Acar, associate professor of molecular, cellular & developmental biology, a faculty member at the Yale Systems Biology Institute, and senior author of the paper. During much of the last half of the 20th century, biology students were taught that mutations of genes that helped species adapt to the environment were passed on through generations, eventually leading to tremendous diversity of life. However, this theory had a problem: advantageous mutations are rare, and it would take many generations for physiological changes caused by the mutation to take root in a population of any given species.

In Search of the Soul

Bernard G. Prusak at Commonweal:

In Search of the Soul presupposes less sympathy for religion on the part of its readers than Why Believe? and How to Believe do. Nonetheless, at just about the middle of the text, Cottingham proposes that “something like a traditional theistic worldview offer[s] a more hospitable framework” for the problems under consideration than does the “materialist consensus” among many philosophers and growing numbers of “nones.” Cottingham’s work consistently exhibits great respect for the findings of the sciences. As he bluntly writes in How to Believe, “there is no future for a religious or any other outlook that tries to contradict or set aside the findings of science.” “We must start from the nature of the universe as we find it,” he states in Why Believe?—and part of what we have found from the “spectacular success” of modern science is that there is “no possibility of a return to an animistic or mythological framework for understanding the world.” There are, however, limits to scientific explanation: most fundamentally, science cannot explain why the laws of nature are what they are. In David Hume’s words, modern science does not inquire into nature’s “ultimate springs and principles.” In Search of the Soul focuses on two problems that resist scientific explanation. First, the fact that “the conscious lifeworld of the individual subject,” though realized in and through the material properties of the human body, isn’t captured by an account of those properties (the “problem of consciousness”). And second, “the fact that moral values and obligations exert an authoritative demand on us, whether we like it or not” (what philosophers call the problem of “strong normativity”). For Cottingham, theism is an interpretive framework—a favorite phrase of his—that can accommodate those problems.

Claude McKay’s Lost Novel

Colin Grant at the NYRB:

Claude McKay, France, 1928

The peripatetic writer Claude McKay was born in Jamaica in 1889 but made in Harlem. As he wrote in his memoir, A Long Way from Home (1937), nothing came close to its “hot syncopated fascination.” His time there was heady and fortuitous. It was a period, recalled Langston Hughes, “when the Negro was in vogue,” and a number of competitors battled for the souls of black folk. They included wealthy, exotic-seeking white voyeurs and Afrophilic benefactors; the National Association for the Advancement of Colored People (NAACP), which aimed to marshal the arts into the service of civil rights; the Universal Negro Improvement Association, Marcus Garvey’s pan-Africanist back-to-Africa movement; and the Communists, who, in opposition to Garvey’s “race first” doctrine, argued that the working class, no matter their color, should put “class first.”

Against the capitalist creeds of scarcity and self-interest, a plan for humanity’s shared flourishing is finally coming into view

Dirk Philipsen in Aeon:

A basic truth is once again trying to break through the agony of worldwide pandemic and the enduring inhumanity of racist oppression. Healthcare workers risking their lives for others, mutual aid networks empowering neighbourhoods, farmers delivering food to quarantined customers, mothers forming lines to protect youth from police violence: we’re in this life together. We – young and old, citizen and immigrant – do best when we collaborate. Indeed, our only way to survive is to have each other’s back while safeguarding the resilience and diversity of this planet we call home.

As an insight, it’s not new, or surprising. Anthropologists have long told us that, as a species neither particularly strong nor fast, humans survived because of our unique ability to create and cooperate. ‘All our thriving is mutual’ is how the Indigenous scholar Edgar Villanueva captured the age-old wisdom in his book Decolonizing Wealth (2018). What is new is the extent to which so many civic and corporate leaders – sometimes entire cultures – have lost sight of our most precious collective quality.

This loss is rooted, in large part, in the tragedy of the private – this notion that moved, in short order, from curious idea to ideology to global economic system. It claimed selfishness, greed and private property as the real seeds of progress.

Sean Carroll’s Mindscape Podcast: Jeremy England on Biology, Thermodynamics, and the Bible

Sean Carroll in Preposterous Universe:

Erwin Schrödinger’s famous book What Is Life? highlighted the connections between physics, and thermodynamics in particular, and the nature of living beings. But the exact connections between living organisms and the flow of heat and entropy remains a topic of ongoing research. Jeremy England is a leader in this field, deriving connections between thermodynamic relations and the processes of life. He is also an ordained rabbi who finds resonances between modern science and passages in the Hebrew Bible. We talk about it all, from entropy fluctuation theorems to how scientists should approach religion.

Why Is America the World’s Police?

Sam Lebovic in the Boston Review:

Most Americans never encounter the simple, brute fact of U.S. military supremacy. Bases are far away; wars in remote places are waged remotely; amid the general fragmentation of social life, those who serve in the military are lumped into particular demographic niches. But on the rare occasions when Americans do think about their military, they are remarkably supportive. The military routinely ranks as the most-trusted institution in polls; even after decades of cuts to all manner of other services, the ever-expanding defense budget remains sacrosanct. Amid general rancor and paranoia about their politics, Americans are overwhelmingly content not only that their military is the world’s most powerful, but also its most expensive: it costs more than the armed forces of the next ten countries combined.

In his new book, historian Stephen Wertheim seeks to explain the origins of this attitude. He zooms in on the pivotal years of World War II, focusing our attention on the frenzied and consequential planning for the postwar world order. Observing a tight network of policy-makers and intellectuals as they drafted the blueprints for what they increasingly thought of as an “American Century,” Wertheim shows that they decided to “attain armed primacy.”

The Deep Humanity of Jewish Law

Zalman Rothschild at The Marginalia Review:

By bringing attention to the very first encounters with uncertainty in early rabbinic literature (the Mishna and Tosefta), Halbertal insightfully demonstrates the ways in which early Jewish legal authorities were keenly interested in “demarcate[ing] and limit[ing] the destabilizing power of doubt and fear of uncertainty.” The heaps of laws surrounding states of uncertainty – which Halbertal correctly describes as some of the most complex areas of Jewish law – were not designed, by virtue of their sheer volume and complexity, to increase anxiety but to quell it. Early rabbinic engagement with doubt was thus an expression of liberation, not legal bondage. Its intent was not to compound hair-splitting laws on top of likely never-to-be-experienced hypotheticals for the sake of burdening Jews with laws where none previously existed, thereby adding to their already extensive repertoire of rules. Rather, this complex system was intended to free up the Jewish practitioner.
