One of the liveliest debates of paleontology is the possibility that the Neanderthals (Homo neanderthalensis) were able to speak like us, with articulate speech, or is expressed as show him in many films ... in grunts.
Analysis obtained with the micro-computer tomography on a very large sample of Neanderthal fossils
of men has made a significant contribution to the discussion, making clear that the hearing in front Neanderthals were not very different from us.
TINY. A team of German and British researchers has tested with the micro-computer tomography ear bones (hammer, anvil and stirrup) of 14 fossils of Neanderthals, linking them to structures of the skull base, the part of the brain where they are nested the hearing components.
The three tiny bones, which form the so-called chain, connect the eardrum to the rest Ear. In the article, published on the journal PNAS (in English), the researchers report that they have also tried to establish the function of the three tiny remnants, comparing its properties with those of the apparatus of modern humans and apes.
EVOLUTIONARY PATH. It turned out that the three tiny structures of our extinct cousins are different from ours. This means that their hearing was different and, consequently, also that the word could be far from that of sapiens? Not necessarily, say the researchers, because the three smaller Neanderthal fragments were still the same functionality of our.
