The work done, in which scholars have participated Center Research on Evolution and Human Behavior (UCM-ISCIII) and the Catalan Institute of Human Paleoecology and Social Evolution (IPHES), has studied the auditory capabilities of our African ancestors.

Until now, experts had tried determine the level of language hominids studying the anatomy of the throat and the bodies involved in the articulation of language.

However, in 2004 the Spanish researchers of this study, all members of the team of scientists Atapuerca, analyzed the auditory abilities of fossils from the Sima of the Bones that houses the remains of individuals primitivos–human genus Homo about 400,000 years ago.

In this work, paleontologists determined Atapuerca these men as we heard, a finding with “direct implications in the language,” he told Efe Carlos Lorenzo, IPHES researcher and co-author of the study.

“Humans have a different hearing sensitivity of chimpanzees, basically because we can hear well at frequencies where talk among two six kilohercios-, the band in which there is the language, “which allows us to distinguish between them phonemes and, So you understand a complex language, “he said.

Such a study, which until then had not been carried out, is that they have now made fossil deposits in South Africa, where the remains of the oldest hominid world, between two and three million years.

“We are proud, because our work in Atapuerca has opened the doors to other sites and analyze fossil points as South Africa, “says Lorenzo

As they did in 2004, these scientists have studied the hearing of two genera. Two relatives Australopithecus and Paranthropus human ancestors but are not intended to directos- find out if they could hear as we do, that is, at frequencies we use.

For this, the multidisciplinary team included experts in 3D who undertook to rebuild the ear bones of fossils to determine if they were able to hear like us, at the same frequencies, and were able to have such complex language as human.

“We have seen that these hominids heard more like chimpanzees, which leads to think that they were not able to speak, because they could not distinguish the sounds, so their language could not be as complex or articulated like ours, “says Lorenzo.

The conclusion of the paper is that the origin Language, therefore, can not be traced back to two or three million years could arise at first, but that is to be found somewhere between hominids makes two million men 400,000 years ago, the Sima of the Bones.
