At position 996 of a collagen chain called COL1A2, the protein extracted from a right parietal bone from Xujiayao, a Middle Pleistocene site in the Nihewan Basin of northern China, carries lysine in 57 distinct peptides and arginine in one. The second Xujiayao specimen sampled, a mandibular ramus, gives 61 lysine-bearing peptides against a single arginine one. Every Denisovan with protein or genom...

Seven and a half meters down in Shanidar Cave, in the Zagros Mountains of Iraqi Kurdistan, the left shoulder blade, or scapula, of a Neanderthal had lain for some 75,000 years with a hole through it. The bone was too soft to pick up. The excavators soaked it where it lay with an acrylic consolidant, Paraloid B72 dissolved in acetone, backed it with cotton gauze, and cut it out of the ground inside...

At the Ōzuka tomb, five horses parade across the stone gateway leading into the burial chamber. Their eyes are large and deliberate. Their harnesses are picked out in careful color. You can tell, from the way the artist rendered their bodies, which animals are male and which are female. Riding them are six human figures, and every one of them is a stick. No faces. No sex. One rider is drawn at rou...

A drained lakebed in the mountains of Jotunheimen doesn’t look like much: gray silt, exposed stone, the odd meltwater channel cutting through it. But in 2022, when the water level at Lake Tesse dropped for its usual spring maintenance, someone walking the exposed mud spotted wood poking out of the ground. Not driftwood. Poles. Dozens of them, still standing upright where they’d been driven into th...

Grave 311 held an eighteen-year-old whose teeth didn’t match their bones. That mismatch is the whole story, so it’s worth sitting with it before anything else. A second molar forms in early childhood, between roughly three and eight years old, and once it’s mineralized it stays chemically frozen at that age forever. Bone collagen is different. It keeps remodeling throughout life, so it mostly reco...

The glyphs sit at the bottom of an inverted L, tucked into the corner of a room that nobody was ever meant to admire. Nine hieroglyphs of mathematics, then two more that don’t belong to any calendar system at all. So says , the text reads, followed by a name: Sak Tahn Waax. White-chested Fox. That’s it. That’s the whole announcement. No royal titles, no cosmic parentage, no k’atun-ending fanfare....

A tibia fragment from a Belgian cave had been sitting in a museum collection, confidently refitted to a particular leg bone, for years. Then researchers sequenced its DNA. It didn’t match. The fragment belonged to a different individual entirely — and only by redoing the refitting and pulling a new sample from the correct bone did the picture come clear. This is the kind of thing ancient DNA analy...

In a 2025 study published in PNAS , researchers led by Christine Ou and Steven Heine asked roughly 250 people in each of 20 countries, spanning six continents, how long they’d slept the night before. France came out on top at 7 hours and 52 minutes. Japan came in last at 6 hours and 18 minutes. The gap between them, an hour and thirty-four minutes, is roughly the difference between a full sleep cy...

Sometime in the decades bracketing the turn of the millennium — after Julius Caesar’s expeditions to Britain but before the Roman legions reached Scotland — a woman’s body was taken apart. Her brain was removed. The base of her skull shows a fracture pattern inconsistent with any known accident: not a fall, not a collapse, not a drop from a height. The break radiates across the right occipital bon...

Kilwa Kisiwani is an island off Tanzania’s southern coast where a medieval port civilization once traded gold, cloth, and Chinese porcelain across the Indian Ocean. Between the twelfth and thirteenth centuries, it was one of the most significant commercial nodes in the world. The tenth-century Arab geographer Al-Masudi documented it. The sixteenth-century Kilwa Chronicle preserved the genealogies...

The scissors are 123mm long. So are the tweezers. Both are iron, nearly pure iron, the kind that only a mature smelting industry can reliably produce. They were buried sometime around the early fifteenth century with a man named Xia Quan, who died in 1411, in Jiangyin County in what is now Jiangsu Province, China. When archaeologists excavated the tomb in 1974, the instruments went to the Jiangyin...

Somewhere beneath the floors of a Bronze Age harbor city on Cyprus, excavators found the bones of pigeons. Not one or two. Dozens. Many were burned, consistent with cooking or deliberate disposal after a meal. Some belonged to juveniles that had never left the nest. And when researchers analyzed the chemical signatures locked in 37 of those bones, they found something that required some explaining...

In the oldest levels of a neighborhood called DK-G South, the houses are large. The largest date to around 2500 BC and cover more than 160 square meters of floor plan. This isn’t surprising for a Bronze Age city. What’s surprising is what happens next. Over the following four centuries, as Mohenjo-daro continued to grow and fill in, housing inequality fell. Not marginally. By around 2100 BC, the G...

Jar 1 at Site 75 sat in forest roughly 70 kilometers northeast of Phonsavan, on the Xieng Khouang Plateau in northern Laos. It was already in poor condition when researchers found it: the sides partially collapsed, the interior open to the elements. But the base was intact, and within the remaining walls, the original sediment deposits had been preserved. Over three field seasons between 2022 and...

Somewhere in the Altai Mountains roughly 59,000 years ago, a Homo neanderthalensis sat still while someone drilled into their tooth with a pointed piece of jasper. We know this because the tooth survived. It came out of Chagyrskaya Cave in southwestern Siberia as specimen Chagyrskaya 64, a lower second molar from an adult individual, and when paleoanthropologist Alisa Zubova of the Russian Academy...

A tooth recovered from Zhoukoudian cave near Beijing in the early 1950s has been sitting in storage for decades. It belongs to a Homo erectus individual who died roughly 420,000 years ago, during a period when the world held at least four distinct human lineages simultaneously. H. sapiens had not yet emerged. Neanderthals were consolidating in the west. A poorly understood group we now call Deniso...

When T. Whitworth described a set of human cranial fragments from Turkana, Kenya, in 1960, he found himself stuck. The skull was thick-walled. The forehead sloped. The mandible was heavy-built in a way that recalled older, more archaic specimens. But there was also a chin. A proper chin, the bony projection below the lower teeth that counts as one of the diagnostic markers of Homo sapiens . Whitwo...

The mound at Baraleti sits near the center of the Javakheti Plateau, and its name tells you something right away. Natsargora means “hill of ashes.” Not a metaphor. When excavations began in 2023, researchers from the Samtskhe-Javakheti Project found out why: layer after layer of burning events, each folded into the next across roughly three thousand years of occupation. People kept coming back to...

Somewhere around 4,000 BC, people living at a promontory above the Sitna river in what is now northeastern Romania built something that didn’t fit. Their settlement had roughly 45 houses, each between 70 and 120 square meters, arranged in orderly rows behind a system of ditches and palisades. The houses were consistent in size, similar in construction, and distributed across a plateau of about 4 h...

The petrous bone is not beautiful. It is a dense, pyramidal wedge buried in the base of the skull, housing the cochlea and semicircular canals, its name taken from the Latin petrosus , meaning rock-like. It weighs almost nothing. You could balance one on your fingertip. Under most circumstances it would register as unremarkable. In paleogenomics, it has become the most fought-over fragment of bone...

Somewhere between 1665 and 1680, a man was buried at the hip with a clay pipe. Traces of soot were still lodged in the bowl. The pipe maker’s stamp on the heel showed a crowned rose and the monogram RW , later traced to Reichard West, a pipe maker recorded in council minutes from Mannheim, Germany, who appears in the historical record between 1673 and 1675 and died around 1675 to 1676. Clay pipes...

Somewhere around 3600 BC, a man was laid to rest in a stone-walled tomb beside Loch Calder, in what is now the far north of mainland Scotland. Later, his son was placed there too. Then, some years after that, his son’s son. The bones of all three eventually ended up gathered together on stone benches inside the northern chamber of a cairn called Tulloch of Assery A, the remains partly disarticulat...

There’s a specific kind of power that lives in restricted space. The Classic Maya k’uhul ajaw — the divine king — expressed his authority partly through enclosure. His palace at the center of the city was internally segmented, its rooms accessible only to those with the right rank. Political decisions happened inside. The public stayed outside. The architecture didn’t merely reflect hierarchy; it...

The Sama people of the Philippines spend their lives on or near the ocean, and much of their foraging happens underwater. Over generations, something measurable shifted in their biology: their spleens got bigger. The spleen functions partly as a reservoir for red blood cells; more spleen means more oxygen available during a long breath-hold dive. The gene variants that produce larger spleens becam...

In 1948, a small team of amateur excavators working a marl quarry near the village of Lehringen in Lower Saxony pulled a wooden spear from sediments laid down during the last interglacial. It was 2.38 meters long, made from yew, still in one rough piece, and it had been lying between the ribs of a straight-tusked elephant ( Palaeoloxodon antiquus ) for approximately 125,000 years. No photographs o...
