Is the ability of humans of speach explainable trough evolution ? on Wed Aug 12, 2009 11:38 am

The origin of language, also known as glottogony, is a topic that has attracted considerable attention throughout human history. The use of language is one of the most conspicuous traits that distinguishes Homo sapiens from other species. Unlike writing, spoken language leaves no explicit concrete evidence of its nature or even its existence. Therefore scientists must resort to indirect methods in trying to determine the origins of language.
Linguists agree that there are no existing primitive languages and that all modern human populations speak languages of comparable complexity. While existing languages differ in terms of the size of and subjects covered by their lexicons, all possess the grammar and syntax necessary for communication and can invent, translate, or borrow the vocabulary necessary to express the full range of their speakers' concepts. All children possess the capacity to learn language and no child is born with a biological predisposition favoring any one language or type of language over another.
The evolution of modern human language required both the development of the anatomical apparatus for speech and also neurological changes in the brain to support language itself, but other species have some of these capabilities without full language ability. The emergence of language use is tied to the full acquisition of these capabilities, but archaeological evidence does not provide an entirely clear picture of these events.
A major debate surrounding the emergence of language is whether language evolved slowly as these capabilities were acquired, resulting in a period of semi-language, or whether it emerged suddenly once all these capabilities were available.

Language, Creation and the Inner Man
by Henry Morris, Ph.D
Probably the most important physical ability distinguishing man from apes and other animals is his remarkable capacity of language. The ability to communicate with others of his own kind in abstract, symbolic speech is unique to man, and the evolutionist has never been able to bridge the tremendous gulf between this ability and the grunts and barks and chatterings of animals.
Some researchers have, of course, made extravagant claims as to the potentiality of teaching chimpanzees to speak, for example, or have developed highly imaginative speculations as to how animal noises may have evolved into human languages. Such notions are, however, not based on real scientific observation or evidence.
Man's brain is quite different from that of chimpanzees, especially in that portion which controls speech, Isaac Asimov notes this:
"Once speech is possible, human beings can communicate thoughts and receive them; they can consult, teach, pool information … Once speech was developed then, the evolution of intelligence proceeded rapidly. The chimpanzee lacks Broca's convolution, but it may have the germs of communication, which could develop rapidly if it ever evolved that part of the brain."1
Unfortunately, one does not acquire a brain capable of abstract thought and intelligent speech (even if "Broca’s convolution" is really all the brain needs to do this) merely by allowing "evolution" to create one because it might be helpful. Two top authorities on supposed human evolution, David Pilbeam and Stephen Gould, anthropologist at Yale and geologist at Harvard, respectively, have pointed out that man's brain shape is not a mere scaled-up replica of the ape’s, but is qualitatively distinct in critical ways.
"Homo sapiens provides the outstanding exception to this trend among primates, for we have evolved a relatively large brain and small face, in opposition to functional expectations at our size … Australopithecus africanus has a rounded braincase because it is a relatively small animal; Homo sapiens displays this feature because we have evolved a large brain and circumvented the expectations of negative allometry. The resemblance is fortuitous; it offers no evidence of genetic similarity."2
Though creationists do not share the credulous faith of the evolutionists that man's unique brain has simply "evolved," they do concur with the inference that this uniqueness has placed an unbridgeable gap between man and any of the higher animals.
Evolutionist George Gaylord Simpson has admitted that there is little possibility of tracing an evolutionary connection between animals and men as far as language is concerned.
"Human language is absolutely distinct from any system of communication in other animals ... It is still possible, but it is unlikely, that we will ever know just when and how our ancestors began to speak."
Since Simpson is a biologist and paleontologist, rather than a linguistics scientist, certain of the younger speculative linguists may feel that he was speaking out of his field and that it may yet be possible to trace such an evolutionary origin of human language. However, most modern linguistic specialists today acknowledge Dr. Noam Chomsky, Professor of Linguistics at Massachusetts Institute of Technology, to be the "world’s foremost linguist" (a term recently applied to him by Dr. John Oller, Chairman of the University of New Mexico Department of Linguistics, while discussing this subject with the writer), and Dr. Chomsky says:
"Human language appears to be a unique phenomenon, without significant analogue in the animal world."
As to whether the gap between animal noises and human language was ever bridged by evolution, Dr. Chomsky states:
"There is no reason to suppose that the ‘gaps’ are bridgeable. There is no more of a basis for assuming an evolutionary development of ‘higher’ from ‘lower’ stages, in this case, than there is for assuming an evolutionary development from breathing to walking."
In other words there is no comparison at all!
The Underlying Unity of Human Language
Chomsky and many other modern linguists have found, not only that there is no connection between animal sounds and human speech, but also that there is a deep commonality between the basic thought patterns of all men, regardless of how diverse their individual languages may be. That is, there is a fundamental connection between all human languages, but no connection at all between human language and animal "language."
In an important recent study, Dr. Gunther S. Stent (Professor of Molecular Biology at the University of California in Berkeley), has drawn the further inference from Chomsky's studies that man has a certain fundamental being which is incapable of being reached by scientific analysis.
"Chomsky holds that the grammar of a language is a system of transformational rules that determines a certain pairing of sound and meaning. It consists of a syntactic component. a semantic component, and a phonological component. The surface structure contains the information relevant to the phonological component, whereas the deep structure contains the information relevant to the semantic component, and the syntactic competent pairs surface and deep structures."
Chomsky and his associates have developed what they call structural linguistics, with its concepts of the "deep" structure and the "surface" structure. The latter involves the ordinary phenomena of different languages and their translation one into the other. The mere fact that people are able to learn other languages is itself evidence of the uniqueness and fundamental unity of the human race. No such possibility exists as between man and animals.
The "deep structure" is the basic self-conscious thought structure of the man himself, and his intuitive formulation of discrete thoughts and chains of reasoning. The vocal sounds which he uses to transmit his thoughts to others may vary widely from tribe to tribe, but the fundamental thought-system is there and is universal among mankind.
"The semantic component has remained invariant and is, therefore, the ‘universal’ aspect of the universal grammar, which all natural languages embody. And this presumed constancy through time of the universal grammar cannot be attributable to any cause other than an innate, hereditary aspect of the mind. Hence, the general aim of structural linguistics is to discover this universal grammar."
Presumably, if this "universal grammar" could ever be ascertained, it would supply the key to man’s original language -- perhaps even its phonology and syntactical structure, as well as its semantic content.
The Unique Origin of Man
Evolutionists, as well as creationists, have in recent years come to believe in the monophyletic origin of all the tribes and races of mankind. Most of the earlier evolutionists, however, believed in man’s polyphyletic origin, thinking that each of the major "races" had evolved independently from a different hominid line. This idea, of course, easily leads to racism, the belief that one race is innately superior to another race. That is, if each race has a long, independent evolutionary history, slowly developing its distinctive character by the lengthy process of random mutation and natural selection, then it is all but certain that there has been a differential rate of evolution as between the different races, with some evolving to higher levels than others. That such racist beliefs were held by all nineteenth-century evolutionist scientists (Darwin and Huxley included) has been thoroughly documented.8
Modern evolutionists, however, repudiate racism, which has become sociologically unpopular in the twentieth century. They now agree (with the Bible) that "God hath made of one blood all nations of men for to dwell on all the face of the earth" (Acts 17:26). Although they are now in practically complete agreement that all present groups of men came originally from one single population of ancestral men, they are currently in complete disarray as to exactly what that lineage may have been. The Australopithecines and the Homo erectus group of supposed hominids are no longer considered man's progenitors, since fossils of true man have been found which are dated earlier than any of these.
"Theorists of human evolution, who may not yet have fully assessed the impact of Leakey’s 1972 discovery, now face an even knottier problem. If members of the human genus flourished as long as four million years ago, then the time when the genus first branched from its ancestral primate stem would necessarily be even earlier. As Taieb and Johanson assert, ‘All previous theories of the origin of the lineage which leads to modern man must now be totally revised.’"9
Maurice Tieg, of the French National Center for Scientific Research, and D. Carl Johanson, of Case Western Reserve University, have thus with their discoveries of three fossil human jaws in Ethiopia) demonstrated that man is "older" than his supposed "ancestors." Creationists do not accept the date of four million years as the age of these jaws, of course, but merely note that the "relative" stratigraphic date has to be "older" than the stratigraphic date of Pithecanthropus, Zinjanthropus, Australopithecus, etc., as accepted by evolutionists.
Not only do these discoveries indicate that man's unique bodily structure has (so far as actual fossil evidence goes) always been distinct from that of apes, but also that he has always had his unique capacity of communication.
"There is even the possibility, Johanson says, that he had ‘some kind of social cooperation and some sort of communication system.’"10
Back to the very beginning of human existence, therefore, in so far as it can be elucidated by archaeological excavation and anthropological analysis, man has always been man, culturally and linguistically as well as physically and mentally.
The Origin of the Different Languages
Consider this ancestral human population, whenever and however it first appeared -- whether several million years ago, newly arrived by an unknown evolutionary process from unknown evolutionary ancestors, or else several thousand years ago, representing the descendants of the handful of survivors of the great Flood. In either case, they must have constituted an originally coherent body of true men, all with the same language and culture.
