Grains of sand prove people – not glaciers – transported Stonehenge rocks

Reading time: 4 minutes
Ask people how Stonehenge was built and you’ll hear stories of sledges, ropes, boats and sheer human determination to haul stones from across Britain to Salisbury Plain, in south-west England. Others might mention giants, wizards, or alien assistance to explain the transport of Stonehenge’s stones, which come from as far as Wales and Scotland.

Olives have been essential to life in Italy for at least 6,000 years – far longer than we thought

Reading time: 6 minutes
How far back does the rich history of Italian olives and oil stretch? My new research, synthesising and reevaluating existing archaeological evidence, suggests olive trees have been exploited for more than 6,000 years. The first Italian olive oil was produced perhaps 4,000 years ago.

How the extinction of ice age mammals may have forced us to invent civilisation

Reading time: 6 minutes
Why did we take so long to invent civilisation? Modern Homo sapiens first evolved roughly 250,000 to 350,000 years ago. But initial steps towards civilisation – harvesting, then domestication of crop plants – began only around 10,000 years ago, with the first civilisations appearing 6,400 years ago.

Small populations of Stone Age people drove dwarf hippos and elephants to extinction on Cyprus

Reading time: 6 minutes
Even though these animals are long extinct, we can draw some conclusions about their likely population because we can estimate their weights from palaeontological information. The dwarf hippo weighed around 130kg, and the dwarf elephant came in at just over 500kg. We also know how to translate weights to estimates of population size, longevity, survival and fertility. We can even use data collected from related species still living today, such as the pygmy hippo and the African elephant, to estimate how fast they would have grown.

Feasting rituals – and the cooperation they require – are a crucial step toward human civilization

Reading time: 7 minutes
Both bread and wine are products of settled society. They represent the power to control nature and create civilization, converting the wild into the tamed, the raw into the cooked – and their transformation cannot be easily done alone. The very act of transforming the wild into the civilized is a social one, requiring many people to work together.

Hindi, Greek and English all come from a single ancient language – here’s how we know

Reading time: 5 minutes
Yet patterns in their descendant languages preserve enough structure to enable us to manage at least a shadowy glimpse of them. The theories and methods pioneered through this work will continue to fuel research into the reconstruction of human ethnolinguistic prehistories worldwide for many years to come.

Talking heads: what toilets and sewers tell us about ancient Roman sanitation

Reading time: 9 minutes
Focusing on life in ancient Rome, Pompeii, Herculaneum and Ostia, I’m deeply impressed by the brilliant engineers who designed these underground marvels and the magnificent architecture that masks their functional purpose. Sewer galleries didn’t run under every street, nor service every area. But in some cities, including Rome itself, the length and breadth of the main sewer, the Cloaca Maxima, rivals the extent of the main sewer lines in many of today’s cities. We shouldn’t assume, though, that Roman toilets, sewers and water systems were constructed with our same modern sanitary goals in mind.

Our stone tool discovery pushes back the archaeological record by 700,000 years

Reading time: 8 minutes
We, and the West Turkana Archaeological Project which we co-lead, had discovered the earliest stone artifacts yet found, dating to 3.3 million years ago. The discovery of the site, named Lomekwi 3, instantly pushed back the beginning of the archaeological record by 700,000 years. That’s over a quarter of humanity’s previously known material cultural history. These tools were made as much as a million years before the earliest known fossils attributed to our own genus, Homo.
