An unambiguous relationship occurs when an anatomical structure is related only to a biological function. By studying anatomy we can know whether or not the individual had this biological function. Tobias considered that in the Homo habilis the Wernicke zone was developed as in modern humans and therefore could speak. Current neuroscience has shown that the Broca and Wernicke areas are related to language, however, not all language resides here (there are more areas of the brain involved in language), nor do they only deal with language. We can no longer be sure, then, that the development of these areas certifies the ability to speak. It is, therefore, a path that, at the moment, is on a dead end.
Homo ergaster With it comes mode II (Acheulian), a way of cutting the stone much more complex than model I (Olduvai: hitting a stone to get a cut). Mode II is very standardized and it is difficult to learn how to make a biface: you have to be very clear about what you want to do and you can’t hit the stone in any way, but you have to follow an orderly sequence. The lithic industry has often been referred to as the first hominids to communicate, understanding that there is a direct relationship between instrument making and language. Certainly, building a tool requires a series of skills such as planning a task, finding and selecting the right raw material, following a proper technique, with precise movements, which has had to be learned, knowing how to choose the best pieces.
We Can Say That Lithic Evolution
Provides clear clues about the development Uae mobile number database the human mind. In this sense, it is interesting to know the process of making utensils, insofar as it provides information on the cognitive abilities involved, which are, at the same time, prerequisites for the emergence of language. However, lithic evolution does not tell us explicitly about how language came into being. Wynn establishes a cognitive increase parallel to the progressive complexity of lithic instruments. Chopper culture  lasted for more than 1 million years without change. As Leroi-Gourhan himself says  (1964), not without a point of irony, how is it possible that in so many hundreds of thousands of years there was no Homo habilisgreat, able to modify the prototype? After this long period of stability there is an unequivocal progress in its manufacture and the bifacial appears.
Certainly, the bilateral symmetry of the tools and the preparation of the core for their realization. Imply a concrete and standardized operating chain, from socially predetermined models. Which is practically impossible to achieve without the help of language. In addition, the creation of tools that will be use to make other tools heralds. The emergence of the typically human ability to proceed recursively. But culture is much more than technology. Utensils alone have little significance; what matters is the contexts to which they are linked, who used them, for what purposes, in what kind of environment, . Some people think that this ability to imagine an end result, to be able to establish a sequence of ordered steps. Would be the beginning of the “syntax” (= with order).
Behind Mode Ii, Then
Would be a structure that would support language. Others, on the other hand, believe that mode II could be learn by imitation. Homo Neanderthalis The problem of the origin of language has focused heavily on the study of Neanderthals. Give their large brains, very complex material culture (Technical Mode III or Monastery), and burials. The paradigm used so far states that Neanderthals could not speak because they did not have a mind like ours. And supports the argument in two objective ways: they do not produce art. According to paleontology, Neanderthals could not speak. It is based on three premises:
The low position of the larynx is an exclusive adaptation of humans. The low position of the larynx is essential for the production of vowels. Which are the core of oral communication. The position of the larynx can be infer from the basicranial anatomy. Especially from the degree of basicranial flexion Let’s try to dismantle this paradigm. It seems that Neanderthals produced art. Gorham Cave in Gibraltar, where in 2012 an engraving possibly made by Neanderthals was discover. But since this is the only vestige we currently have of a representation of Neanderthals. We need to provide evidence against the second of the arguments.
