Researchers have discovered the cave art created by Neanderthals in Gorham's cave above the Mediterranean Sea. The art work dates back to at least 39,000 years.

The researchers were not able to find out what the Neanderthal artists may have been trying to say with this geometric carving but they have devoted their lot of time to know how it was made.

Since 1980s, a team led by zoologist Clive Finlayson, the director of the Gibraltar Museum, has been unearthing the cave. It was found that the Neanderthals who called the cave home consumed fish, shellfish and birds, and maybe they survived longer than their counterparts somewhere else in Europe.

According to researchers, it can be said that Neanderthals were more knowledgeable than previously considered. From the other studies, it was found that Neanderthals buried their dead, adorned themselves with black feathers and were skilled in hunting games.

In July, Finlayson's colleague Francisco Pacheco moved on the cave floor through a narrow passage to reach the chamber. They saw the drawings which were carved on a horizontal platform that is placed 40 centimeters from the bedrock such as natural coffee table.

The drawings covered the area of about 20 by 20 centimeters and are up to a few millimeters deep. Finlayson is sure that the drawing was made by Neanderthals. A layer of sediments that once covered the engraving have stone tools those made by Neanderthals.

Humans didn't come at Gorham's Cave until more than 10,000 years later, and long after Neanderthals were gone. To better understand the art, researchers tried replicating them by using the original Neanderthal stone tools.

"We conclude this engraving represents deliberate design conceived to be seen by its Neanderthal maker and, considering its size and location, by others in the cave as well. It follows the ability for abstract thought was not exclusive to modern humans", wrote the authors.
