A series of parallel lines carved on animal bones 1.2-1.4 million years ago, may serve as the earliest example of human symbolic behavior. Experts from the University of Bordeaux claim that no action, carrying the practical value (for example, cutting the animal) could not leave these marks. However, many other scientists believe that the ability to genuine symbolic thinking emerged much later — already in Homo sapiens. 8-centimeter bone that caused this controversy, was excavated in a cave Kozarnik in northwestern Bulgaria. The other bones found in the same location along the edge 27 cuts applied. Scientists have studied them say it can not be the marks of cutting — at this point there is simply nothing to cut off the carcass. So, according to Jean-Luc Guadelli, "this is nothing more than symbolism."
• This bones — more than a million years
When cutting production of the ancient people often left their stone tool marks on the bones. But the French and Bulgarian researchers who analyzed the find of Kazarniki, argue that the parallel cuts inflicted too precisely to be dropped as a result of cutting the carcass. What are these symbols mean, scientists find it difficult to say. However, they suggest that this kind of language.
Which of these hominids struck the mark — hard to say. Group Guadelli found near the bones of the same age baby tooth that belonged to some early Homo, but researchers find it difficult to name a specific type. This is most likely Homo erectus. Bone, on which a thread belonging to unknown ruminant.
