World's earliest JEWELLERY is discovered: 150,000-year-old shell beads found in a Moroccan cave were likely worn as earrings or strung on a necklace
The world's earliest known piece of jewellery has been found by archaeologists, who say the 150,000-year-old beads may have been worn as earrings or on a necklace.
A set of 33 shell beads were discovered between 2014 and 2018 at the mouth of Bizmoune Cave, about 10 miles from Essaouira, a city on Morocco's Atlantic coast.
The beads date to between 142,000 and 150,000 years ago and were found by a team, including anthropologists, from the University of Arizona in Tucson.
Lead author, Steven L. Kuhn, said this is the earliest known evidence of a form of nonverbal human communication and hints at the origin of our cognitive skills.
This suggests that human behaviour of saying things about themselves through jewellery and other adornments, started much earlier than previously thought.

He said: 'They were probably part of the way people expressed their identity with their clothing,' and are 'the tip of the iceberg for that kind of human trait.'
'They show that it was present even hundreds of thousands of years ago, and that humans were interested in communicating to bigger groups of people than their immediate friends and family.'
This is something humans still do today, according to Kuhn, who said it doesn't just include jewellery, but can be something as simple as honking a car horn.
'You think about how society works – somebody's tailgating you in traffic, honking their horn and flashing their lights, and you think, 'What's your problem?'' Kuhn said.
'But if you see they're wearing a blue uniform and a peaked cap, you realise it's a police officer pulling you over.'
The beads uncovered by Kuhn and his collaborators were made from sea snail shells, and each measures roughly half an inch long.
Holes in the centre of the beads, as well as other markings from wear and tear, indicate that they were hung on strings or from clothing, Kuhn said.
The beads are like many others found at sites throughout northern and southern Africa, but previous examples date back to no older than 130,000 years.
Ancient beads from North Africa are associated with the Aterian, a Middle Stone Age culture known for its distinctive stemmed spear points, whose people hunted gazelles, wildebeest, warthogs and rhinoceros, among other animals.The beads serve as potential clues for anthropologists studying the evolution of human cognition and communication.
Researchers have long been interested in when language appeared. But there was no material record of language until just a few thousand years ago, when humans began writing things down.
The beads, Kuhn said, are essentially a fossilised form of basic communication, adding that while we don't know what they mean, they are clearly symbolic objects deployed in a way other people could see them.

Rather than painting their bodies or faces with ochre or charcoal, as many people did, the beads' makers made something more permanent, Kuhn said, suggesting the message they intended to convey was a lasting and important one.
In many ways, the beads raise more questions than they answer. Kuhn said he and his colleagues are now interested in learning why the Aterian people felt the need to make the beads when they did.
They're exploring several possible explanations. One, Kuhn said, involves a growing population; as more people began occupying North Africa, they may have needed ways to identify themselves.
It is also possible that people in North Africa started using the method of communication at a time when the climate was cold and dry.
They may have developed clans or other allegiances to protect limited resources, then perhaps used the beads to express their ethnicity or other identity to show they belonged in a certain area, Kuhn said.
'It's one thing to know that people were capable of making them,' Kuhn said, 'but then the question becomes, 'OK, what stimulated them to do it?''
The findings have been published in the journal Science Advances.
