“Spectacular, ridiculous, experimental things”

Reading The Tomb of the Mili Mongga by Samuel Turvey for New Scientist, 6 March 2024

Pity the plight of evolutionary biologist Samuel Turvey, whose anecdotal accounts of fossil hunting in a cave near the village of Mahaniwa, on the Indonesian island of Sumba, include the close attentions of “huge tail-less whip scorpions with sickening flattened bodies, large spiny grabbing mouthparts, and grotesquely thin and elongated legs”.

Why was a conservation biologist hunting for fossils? Turvey’s answer has to do with the dual evolutionary nature of islands.

On the one hand, says Turvey, “life does spectacular, ridiculous, experimental things on islands, making them endlessly fascinating to students of evolution.”

New Caledonia, a fragment of ancient Gondwana, boasts bizarre aquatic conifers and even shrubby parasitic conifers without any roots. Madagascar hosts a lemur called the aye-aye; a near primate equivalent to the woodpecker. But my personal favourite, in a book full of wonders, pithily described, is the now extinct cave goat Myotragus from predator-free Majorca and Menorca. Relieved of the need to watch its back, it evolved front-facing eyes, giving it the disconcerting appearance of a person wearing a goat mask.

But there is a darker side to island life: it’s incredibly vulnerable. The biggest killers by far are visitations of fast-evolving diseases. European exploration and colonisation between the 16th and 19th centuries decimated the human populations of Pacific archipelagos, as a first wave of dysentery was followed by smallpox, measles and influenza. Animals brought on the trip proved almost as catastrophic to the environment. Contrary to cliche, westerners on the island of Mauritius did not hunt the dodo to extinction; rats did. And let’s not forget Tibbles, the cat that’s said to have single-handedly (pawedly?) wiped out the Stephens Island wren, a tiny flightless songbird, in 1894.

There are lessons to be learned here, of course, but Turvey’s at pains to point out that islands are accidents waiting to happen. Islands are by their very nature sites of extinction. They may be treasure-troves of evolutionary innovation, but most of their treasures are already extinct. As for conserving their wildlife, Turvey wonders how, without a good understanding of the local fossil record, “we even define what constitutes a ‘natural’ ecosystem, or an objective restoration target to aim for”.

A tale of islands and their ephemeral wonders would alone have made for an arresting book, but Turvey, a more-than-able raconteur, can’t resist spicing up his account with tales of Sumba’s resident mythical wild-men, the “Mili Mongga”, who, it is said, used to build walls and help out with the ploughing — until their habit of stealing food got them all killed by the infuriated human population.

Why should we pay attention to such tales? Well, Sumba is only about 50 kilometres south of Flores, where a previously unknown (and, at just over a metre tall, ridiculously small) hominin was unearthed by an Australian team in 2003.

If there were hobbits on Flores, might there have been giants on Sumba? And might surviving mili mongga still be lurking in the forests?

Turvey uses the local island legends to launch fascinating forays into the island’s history and anthropology, to explain why large animals, fetched up on islands, grow smaller, while small animals grow larger, and also to have an inordinate amount of fun, largely at his own expense.

When one villager describes a mili mongga skull as being two feet long, and its teeth “as long as a finger”, “I got the feeling,” says Turvey, ”that there might now be some exaggeration going on.” Never say never, though: soon Turvey and his long-suffering team are following gamely along on missions up crags and past crocodile-infested swamps and into holes in the ground — sometimes where other visitors, from other villages, habitually go to relieve themselves.

“There was the cave that some village kids told us contained a human skull, which turned out to be a rotten coconut under some bat dung,” Turvey recalls. “There was the cave that was sacred, which seemed to mean that no one could remember exactly where it was.”

Turvey’s more serious explorations unearthed two new mammal genera (both ancestral forms of rat). It goes without saying, I should think, that they did not bring back evidence of a new hominin. But what’s not to enjoy about a tall tale, especially when it’s used to paint such a vivid and insightful portrait of a land and its people?

“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.
