Today we can only guess as to why a group of Neanderthals built a series of large stalagmite structures in a French cave - but the fact they did provides a rare glimpse into our extinct cousin's potential for social organisation in a challenging environment.
Gone are the days when we thought of Neanderthals as crude and unintelligent.
Archaeological evidence now suggests they were capable of symbolic thought, had a basic knowledge of chemistry, medicine and cooking, and perhaps some capacity for speech. They may even have taught modern humans new artisanal skills when the two species met and interbred.
A reassessment of evidence from Bruniquel cave, near Toulouse in south-west France, suggests even more Neanderthal sophistication. In one chamber, 336 metres from the cave entrance, are enigmatic structures - including a ring 7 metres across - built from stalagmites snapped from the cave floor.
Natural limestone growths have begun to cover parts of the structure, so by dating these growths a team led by Jacques Jaubert at the University of Bordeaux could work out an approximate age for the stalagmite constructions.

The stalagmite structures are 50 centimetres high in places, says Jaubert. They are built from around 400 individual stalagmites with a combined weight of about 2 tonnes.
"That must take time [to shift]," he says - although exactly how long it took the Neanderthals to build the structures isn't clear. "As often in prehistory, measuring time is not easy."
What we do know is that the structures were built in dark, challenging conditions and the builders had no natural light to help them. Indeed, Jaubert's team found traces of fire at several points around and on the structures.
The simplest explanation is that the structures served as some sort of shelter or refuge - perhaps the stalagmite "walls" supported a roof of perishable wood, for example - but there are no other artefacts and very few signs of domestic activity in the chamber beyond the presence of one charred bone fragment that possibly belonged to a bear or large herbivore.
That draws comparisons with much later cave sites such as Chauvet, a 30,000-year-old site of modern human occupation that is rich in cave art but contained a mere handful of artefacts. So perhaps Bruniquel - like Chauvet - served some ritual role. If so it would provide more evidence for the Neanderthal's capacity for symbolic thought.
Paola Villa at the University of Colorado in Boulder has previously called for Neanderthals to be considered on the same sort of intellectual plane as modern humans. She says the new paper lends weight to her argument.
Villa points out that the Bruniquel cave was actually discovered and studied in the 1990s. Even then, it seemed likely that Neanderthals had arranged the stalagmites, because carbon dating of the single charred bone found at the site suggested the site predated the arrival of modern humans in Europe. But until now few researchers were really aware of the structures' existence.
This is partly because the previous work wasn't published in the international scientific literature, but Villa thinks there was another reason the Bruniquel finds were overlooked in the late 90s and early 2000s: mainstream scientific thinking at the time simply rejected the idea of Neanderthals as intelligent and sophisticated.
"[It] ran against the prevailing and damning views of Neanderthal inferiority compared to modern humans," Villa says.

But I'm not so sure. I allow the thought that despite our technology and social advances (or are they?) we are just a bit dumber than our chronologically close ancestors used to be. After all, we don't have to be so smart to survive under current circumstances.
Please indulge me. I’ll elucidate a bit.
The oldest known fossil, discovered in Kenya by the Leakeys, was dated 18,000,000 years old.
So too the next oldest, discovered in the Kongo by the Leakeys, and dated 14,000,000 years old.
This continues with a lot of ‘folks’, going down the ladder. Suzy, Paranthropus boisei, … Creation of Humankind around 432,000 years ago (Sitchin and others), Afruikans in America 130,000 BC (CNN article, see realhistoryww.com).
When exactly did the Neanderthals ‘show-up’?
How did the Neanderthals become a separate species? With whom did they mix to form a separate species?
According to established historians as McCabe, Volney, etc, the white-man did not emerge from his cave until approximately 3500 years ago. With whom therefore did the Afruikan (first people) mix to produce the Neanderthal, ‘who’ is mostly depicted white?
