How disease shaped humanity’s past

DISEASE historians have a problem. While examining samples of ancient human DNA, geneticists have come across genes belonging to the plague bacterium, Yersinia pestis, revealing that it ravaged Eurasia 5000 years ago. That’s nearly 3500 years before the “first plague”, also known as the Justinian plague, after the Roman emperor of the day. What to…

Cracking the linguistic code
EVERY year since 2008, with a gap for Covid-19, linguist Nicholas Evans has taken a banana boat six hours along the coast of New Guinea to reach a village called Bimadbn. There he spends the next six weeks documenting a previously unwritten language called Nen… This article first appeared in The Observer on 25 October 2025. To…

The modern foundling wheel
WHEN Romina discovered she was pregnant in 2021, she was 39 years old and homeless, without a euro to her name. She did what many a lonely and frightened woman has done throughout history, on learning that she was going to have a baby, and pretended she wasn’t. “If you don’t think about it, it…

Childcare issues
THE story of human evolution has undergone a distinct feminisation in recent decades. Or, rather, an equalisation: a much-needed rebalancing after 150 years during which, we were told, everything was driven by males strutting, brawling and shagging, with females just along for the ride. This reckoning has finally arrived at language… This article first appeared…

Science on the catwalk
IRIS van Herpen leads photographer Ilvy Njiokiktjien and me into a cluttered storeroom and I shut the door. “Ooh!” we gasp, as we gaze at a board that van Herpen holds up in the darkness. Outside the room, the board looked much like a child’s glue painting, with silicone piping arranged on it in a…

How migrants shape language

by
ABOUT 5,000 years ago, a group of herders living in the grasslands north of the Black Sea headed west, taking their animals with them. They got as far as the Carpathian Basin — the western extremity of the vast Eurasian steppe centered on modern Hungary — but their descendants pushed farther, and within 1,000 years…

Could English ever die?
GIVEN that a staggering 1,500 languages could vanish by the end of this century, by some estimates – close to a quarter of the world’s total – some may find it obscene to even ask this question. English is certainly not on the endangered list. As the one truly global language, it is more often…

DNA from dirt
IT was an otherwise ordinary day in 2015 when Viviane Slon had her eureka moment. As she worked at her computer, the results revealed the sample she was examining contained human DNA. There was nothing so unusual about that in itself: at the time, the ancient DNA (aDNA) revolution was in full swing, and surprising…

Review: the Homo derby
IN an institute in Germany, scientists are growing “Neanderthalised” human brain cells in a dish. These cells form synapses and spark as they would have done in a living Neanderthal as she (they are female cells) foraged or breastfed or gazed out of a cave mouth at dusk. That is the spine-tingling opening gambit of…
