Rogues and heroes

Reading Sam Miller’s Migrants: The Story of Us All for the Telegraph, 23 January 2023

The cultural opprobrium attached to immigration has been building at least since Aristotle’s day, according to Sam Miller’s flawed, fascinating stab at a global history of migration.

Today, “having a permanent home and a lifelong nationality are considered normal, as if they were part of the human condition.” On the contrary, says Miller: humankind is the migratory species par excellence, settling every continent bar Antarctica, not once, but many times over.

Mixed feelings about this process have a deep anthropological foundation. Forget national and regional rivalries; those came later, and are largely explanations after the fact. What really upsets settled people is the reminder that, long ago, their kind chose to live an urban life and became less as a consequence: less wily, less tough, less resilient. The emergence of the first cities coincided with the first poems in uneasy praise of wild men: think of Mesopotamian Enkidu, or Greek Heracles. Aristotle, writing in 330 BC, declares that “he who is without a city-state by nature, and not by circumstance, is either a rogue or greater than a human being” — a wonderfully uneasy and double-edge observation that acknowledges a pre-urban past populated by formidable feral heroes.

Athenians suppressed this awareness; they were the first Western people to take pride in being, in Herodotus’s words, “the only Greeks who never migrated.” Ming Dynasty China performed the same flim-flam, a 15th-century administrator declaring: “There exists a paramount boundary within Heaven and Earth: Chinese on this side, foreigners on the other. The only way to set the world in order is to respect this boundary”.

“History books have, on the whole, been written by the sedentary for the sedentary,” says Miller, and naturally reflect a settled people’s chauvinism. The migration stories we learned at school are often wrong. The Vandals who “sacked” Rome in 455, did not, as a general rule, kill or rape or burn.

Alas, neither did they write; nor did the Roma, until the nineteenth century; nor did the (handsomely literate) Chinese of Victorian London. Migrants rarely find time to write, and where first-person accounts are missing, fantasy is bred. Some of it (Asterix) is charming, some of it (Fu Manchu) is anything but.

Miller thinks that humans naturally emigrate, and our unease about this is the result of pastoralism, cities, and other historical accidents.

The trouble with this line of argument is that there are umpteen “natural” reasons why people move about the earth. Humans naturally consume and lay waste to their immediate environment. Humans naturally overbreed. Humans naturally go to war. Why invoke some innate “outward urge”?

Different distances on the human story allow one to tell wildly different stories. If you follow humanity through deep time, our settlement of the almost the entire planet looks very much like manifest destiny and we’ll all surely end up on Mars tomorrow. If on the other hand you trace the movements of people over a few dozen generations, you’ll discover that, absent force majeure, people are homebodies, moving barely a few weeks’ walking distance from their birthplaces.

What is migration, anyway? Not much more than a hundred years ago, women regularly “migrated” (as Miller says, “it might take as long to cross a large English county as it would to fly halfway around the world today”) to marry or to work as governesses, domestic servants and shop workers. And yet they would never have called themselves “migrants”.

Miller, in a praiseworthy bid to tell a global story, adopts the broadest possible definition of migration: one that embraces “slaves and spouses, refugees and retirees, nomads and expats, conquerors and job-seekers.”

Alas, the broader one’s argument, the less one ends up saying. While they’re handsomely researched and stirringly written, I’m not sure our concepts of migration are much enriched by Miller’s brief tilts at historical behemoths like slavery and the maritime spice route.

What emerges from this onion of a book (fascinating digressions around no detectable centre), is, however, more than sufficent compensation. We have here the seed of much more enticing and potentially more influential project: a modern history that treats the modern nation state — pretending to self-reliance behind ever-more-futile barriers — as but a passing political arrangement, and not always a very useful one.

In view of the geopolitical crises being triggered by climate change, we may very soon need (or else be forced by circumstances) to come up with forms of government outside the rickety and brittle nation state. And in that case, peripatetic perspectives like Miller’s may be just what we need.

 

“The idea that life is absurd bothers him”

Reading Life As Told by a Sapiens to a Neanderthal by Juan José Millás and Juan Luis Arsuaga for the Telegraph, 27 July 2022

In 2013 the oldest known human DNA was discovered, in a complex of caves in the Sierra de Atapuerca in northern Spain. It belongs to an early hominid, Homo heidelbergensis, who lived 400,000 years ago, and to whom we owe the invention of the fireplace.

Arsuaga has built an illustrious career around excavations in Atapuerca, a site humans have occupied continuously for a million years, from the dawn of Homo sapiens to the bronze age. He knows a lot about how humans evolved, and he is an eloquent communicator. “As he talked,” the novelist Juan José Millás recalls, “I realised what a great sense of the theatrical Arsuaga had. He was a master of oral storytelling. He knew when he had his audience, and when he was running the risk of losing them. He endeared himself by combining intellectual precision with a kind of helplessness.”

It’s Aruaga’s eloquence that first persuaded Millás that the two of them should collaborate on a book — a Boswellian confection in which Millás (humble, curious, a klutz, and frequently brow-beaten) follows Arsuaga around with a dictaphone capturing the great man’s observations. “In Spain,” he remarks, early on, “there are two principal periods: the first runs from the Neolithic to 1958, at which point the social planning by the Opus Dei technocrats comes in. Until then, the countryside was a place full of people, full of voices, life here was not a sad thing, there were children running around. It would be like walking down the street. By 1970, the countryside was empty, there was nobody left.”

Millás casts Arsuaga as the representative of Homo sapiens: articulate, eclectic, self-aware and tragical. Millás casts himself as Homo neanderthalis, not quite as quick on the uptake as his more successful cousin. Neanderthals are a species not exactly lost to history (Sapiens and Neanderthals interbred, after all) but no longer active in it, either.

The idea is that Arsuaga the high-brow leads our beetle-browed narrator hither and thither across northern Spain, on foot or in his trusty Nissan Juke, up lost valleys (to understand the evolution of hunting) and through deserted playgrounds (to grasp the mechanics of bipedalism), past market stalls (to grasp the historical significance of diet) and into a sex shop (to discuss the relative size of primate testicles) and building, bit by bit, a dazzling picture of the continuities that exist between our ancient and contemporary selves.

For many, the devil will be in the detail. Take, for example, Millás’s Neanderthals. He is not exactly wrong in what he says about them, but he is writing, in the most general and allusive terms, into a field that is developing frighteningly fast. It‘s hard, then, for us to know how literally to take the author’s showier gestures. Millás says, about that famous interbreeding, that “The Sapiens, being the smart ones, did it out of vice, while the Neanderthals, who were more naïve, did it out of love.” With Neanderthal intelligence and sociality a topic of so much fierce debate, such statements as this may be met with more scepticism than appreciation.

This is as much a buddy story as it is a virtuosic work of popular science. In unpacking our evolutionary past, Millas also brings his human subject to light. Arsuaga holds to the tragic view of life espoused by the fin de siecle Spanish essayist Miguel de Unamuno. Millás, a more common-or-garden depressive, finds Arsuaga’s combination of high spirits and annoyance hard to read. Deposited on the outskirts of Madrid, and half suspecting he’s been actually thrown out of Arsuaga’s Nissan, Millás realises that the palaeontologist “experiences sudden bursts of sadness that he sometimes conceals beneath an ironic demeanour, and sometimes beneath passing bad moods. I think the idea that life is absurd bothers him.”

Aruaga’s tragic sense entends to the species. We are the self-domesticating species: “To the Neanderthal,” he says, “the Sapiens must have seemed like a teddy bear.” We have evolved social complexity by shedding the adult seriousness we observe in less social mammals. (“I’ve been to Rwanda, looking at old gorillas,” says Aruaga, “and I can assure you they don’t play at all, they don’t laugh at anything.”) Over evolutionary time, we have become more playful, more infantile, more docile, and we have done this by executing, imprisoning and marginalising those who exhibit an ever-expending list of what we consider anti-social traits. So inanity will one day conquer all.

I wish Millás was a less precious writer. Very early on the pair arrive at a waterfall. “What had we come here for?” Millás writes: “in principle, to see the waterfall, and perhaps so the waterfall could see us, too.” Such unredeemable LRBisms are, I suppose, a form of protective coloration, necessary for a novelist and poet of some reputation: an earnest of his devotion to propah lirtritchah.

It’s when Millás forgets himself, and erases the distance he meant to maintain between boffins and scribblers, that Life becomes a very special book indeed: a passionate, sympathetic portrait of one life scientist’s world view.

Tally of a lost world

Reading Delicious: The evolution of flavor and how it made us human by Rob Dunn and Monica Sanchez for New Scientist, 31 March 2021

Dolphins need only hunger and a mental image of what food looks like. Their taste receptors broke long ago, and they no longer taste sweet, salty or even umami, thriving on hunger and satisfaction alone.

Omnivores and herbivores have a more various diet, and more chances of getting things badly wrong, so they are guided by much more highly developed senses (related, even intertwined, but not at all the same) of flavour (how something tastes) and aroma (how something smells).

Evolutionary biologist Robb Dunn and anthropologist Monica Sanchez weave together what chefs now know about the experience of food, what ecologists know about the needs of animals, and what evolutionary biologists know about how our senses evolved, to tell the story of how we have been led by our noses through evolutionary history, and turned from chimpanzee-like primate precursor to modern, dinner-obsessed Homo sapiens.

Much of the work described here dovetails neatly with work described in biological anthropologist Richard Wrangham’s 2009 book Catching Fire: How cooking made us human. Wrangham argued that releasing the calories bound up in raw food by cooking it led to a cognitive explosion in Homo sapiens, around 1.9 million years ago.

As Dunn and Sanchez rightly point out, Wrangham’s book was not short of a speculation or two: there is, after all, no evidence of fire-making this far back. Still, they incline very much to Wrangham’s hypothesis. There’s no firm evidence of hominins fermenting food at this time, either — indeed, it’s hard to imagine what such evidence would even look like. Nonetheless, the authors are convinced it took place.

Where Wrangham focused on fire, Dunn and Sanchez are more interested in other forms of basic food processing: cutting, pounding and especially fermenting. The authors make a convincing, closely argued case for their perhaps rather surprising contention that “fermenting a mastodon, mammoth, or a horse so that it remains edible and is not deadly appears to be less challenging than making fire.”

“Flavor is our new hammer,” the authors admit, “and so we are probably whacking some shiny things here that aren’t nails.” It would be all too easy, out of a surfeit of enthusiasm, for them distort their reader’s impressions of a new and exciting field, tracing the evolution of flavour. Happily, Dunn and Sanchez are thoroughly scrupulous in the way they present their evidence and their arguments.

As primates, our experience of aroma and flavour is unusual, in that we experience retronasal aromas — the aromas that rise up from our mouths into the backs of our noses. This is because we have lost a long bone, called the transverse lamina, that helps to separate the mouth from the nose. This loss had huge consequences for olfaction, enabling humans to search out convoluted tastes and aromas so complex, we have to associate them with memories in order to individually categorise them all.

The story of how Homo sapiens developed such a sophisticated palette is also, of course, the story of how it contributed to the extinction of hundreds of the largest, most unusual animals on the planet. (Delicious is a charming book, but it does have its melancholy side.)

To take one dizzying example, the Clovis peoples of North America — direct ancestors of roughly 80 per cent of all living native populations in North and South America — definitely ate mammoths, mastodons, gomphotheres, bison and giant horses; they may also have eaten Jefferson’s ground sloths, giant camels, dire wolves, short-faced bears, flat-headed peccaries, long-headed peccaries, tapirs, giant llamas, giant bison, stag moose, shrub-ox, and Harlan’s Muskox.

“The Clovis menu,” the authors write, “if written on a chalkboard, would be a tally of a lost world.”
