Cavemen on the costas: Neanderthals travelled to the Spanish coast in search of the Summer sun – just like modern-day holidaymakers
- 30,000-year-old Neanderthal footprint shows our early ancestors headed south
- Early human ancestors went to Gibraltar to avoid the worst of the last ice age
- The discovery supports theories Neanderthals died out later than thought
Early humans in Europe travelled south towards sunny Spain to avoid the cold and give them better chances of survival, a new study suggests.
Neanderthals, an early relative of humans, fled other parts of Europe during the last ice age and arrived in Gibraltar, the southern tip of the Iberian Peninsula.
Spanish scientists have based this on the discovery of a footprint found in the quarry in the ‘climate refuge’ of Gibraltar, which is located on Spain’s southern tip.
The Spanish team used advanced photographic imaging and light techniques to ascertain the age and owner of the footprint – a Neanderthal teenager who lived around 30,000 years ago.
Europe at the time was going through the last ice age when glaciers covered huge parts of the Earth and snow covered everything north of the River Ebro, which runs along the north of Spain.
‘There were few family members and they came to spend the summer on the south coast of the peninsula just like today,’ Joaquín Rodríguez Vidal, professor of geodynamics and paleontology at the University of Huelva, Spain, told El País.

The footprint indicates the Iberian peninsula was a sanctuary for this species at that time.
‘In Gibraltar, there must have been a small group that arrived in the area by following their prey,’ Professor Vidal said. ‘They were seasonal settlements.
‘They found a varied diet here and a climate that, according to the levels of pollen, was much more likely to guarantee survival.’
The study also supports recent scientific theories that the primitive species of human existed more recently than previously thought.
The research team based their conclusion of the discovery of fossilised footprints beneath the ground, found in the Catalan Bay quarry on the east side of Gibraltar, which they analysed with photogrammetric techniques.
One of these footprints, which was measured as 6.6 inches long, 2.7 inches wide and 0.8 inches deep, was identified as belonging to a Neanderthal teenager estimated at about 4 foot 3 inches tall, made 28,300 years ago.

‘The photogrammetry has provided evidence on the shape of the toes, heel, arch and the footpads,’ said Fernando Muñiz, professor of crystallography and mineralogy from the University of Seville.
‘There is no doubt that it is from a hominoid. The comparison with other footprints shows that it belongs to a Neanderthal.’
Neanderthals, or Homo neanderthalensis, are an extinct species of humans that are thought to have lived until about 40,000 years ago.

The footprint’s estimated age was obtained using luminescence dating, a technique that determines how long ago mineral grains were last exposed to sunlight.
The estimated date of 28,000 years supports recent theories that our early ancestors went extinct later than previously thought.
A research paper published in Nature in 2006 questioned whether Neanderthals became extinct 40,000 years ago due to the discovery of Neanderthals’ stone tool remains dating between 24,000 and 28,000 years prior.
The research was seminal in its suggestion that Homo neanderthalensis and today’s humans, Homo sapiens – which arrived in Europe from Africa later – co-existed for as long as 4,000 years.

The site of that discovery was in Gibraltar’s Gorham’s Cave, where Neanderthal artefacts were first discovered more than 60 years ago.
However, the new research found ‘no evidence of violence’ and no traces of Homosapiens in this area, which questions the theory that competition between the two species caused Neanderthals’ extinction.
‘The groups were very small and were forced into consanguinity, which is more likely to be the cause of their extinction,’ said Professor Vidal.
The research team, which published their study in Quaternary Science Reviews, found a range of mammalian footprints from other animals that would have travelled south to escape the cold, including to elephants, goats, bovids and felines.
WHO WERE THE NEANDERTHALS?
The Neanderthals were a close human ancestor that mysteriously died out around 50,000 years ago.
The species lived in Africa with early humans for hundreds of millennia before moving across to Europe around 500,000 years ago.
They were later joined by humans taking the same journey some time in the past 100,000 years.
The Neanderthals were a cousin species of humans but not a direct ancestor – the two species split from a common ancestor – that perished around 50,000 years ago. Pictured is a Neanderthal museum exhibit
These were the original ‘cavemen’, historically thought to be dim-witted and brutish compared to modern humans.
In recent years though, and especially over the last decade, it has become increasingly apparent we’ve been selling Neanderthals short.
A growing body of evidence points to a more sophisticated and multi-talented kind of ‘caveman’ than anyone thought possible.
It now seems likely that Neanderthals buried their dead with the concept of an afterlife in mind.
Additionally, their diets and behaviour were surprisingly flexible.
They used body art such as pigments and beads, and they were the very first artists, with Neanderthal cave art (and symbolism) in Spain apparently predating the earliest modern human art by some 20,000 years.
