Homo Sapiens vs Neanderthals | The Evolution of Language

Homo sapiens appeared about 200,000 years ago and finally we made our first appearance on the family tree our brain had grown the largest of all surviving humans it wasn't just acquiring a large brain which allowed us to survive another species had an equally large brain the Neanderthals they appeared about 300,000 years ago their brain size was exactly the same as ours in body height they were also about the same but slightly more robust Neanderthals migrated to Europe in the middle of the Ice Age they were a hearty race as well as being good hunters but they are now gone from the miracle planet and we remain from archaeological evidence it seems that both Neanderthal and Homo sapiens shared very similar abilities in this part of southwestern France there are many Neanderthal sites the ratio do prehistoric site was discovered by chance while the landowner was digging in his garden there are Neanderthal remains here from 70,000 years ago dr.

Genest even believes that they were capable of thoughts similar to ours the skeleton of this Neanderthal is exactly as it was found perhaps evidence that they had thoughts of some afterlife and buried their dead mizuki Vadhu male Lagonda particular et de Lomo sapiens sapiens say pitoni would a technique of a developer's Association play complex doctrine sukira developed the system technique McDonald momento yo how we see develop a unique el único tree of knowledge el Aloha you know plays particular policy Maj Palo a presentational figurative usha mattock ESO la una loca NEPA Shalom Daniel Delta the two different species of humans seemed so similar what gave us the edge there's an intriguing theory that might provide an answer dr. Jeffery late one of New York's Mount Sinai School of Medicine compared the two skulls and then noticed a minor difference in the shape - like Neanderthals and when you study the bottom of skull name it was at the base of the skull with Neanderthals the central part of the base is flat but in the modern humans cow it is rounded the difference correspondent to the upper side of the throat where the larynx or voice box is situated as well as studying human skulls he also studied living apes they too had flat central bases in their skulls just like the Neanderthal strangely there is still a trace of Neanderthal in all of us but it doesn't last very long remarkably baby humans have the same configuration so if you look at a newborn baby its voice box is also all the way up in the throat and babies always breathe through the nose and have the ability to breathe and swallow almost at the same time something remarkable happens in human development our voice box starts a journey down into the neck unlike any other mammal we start in one place but we end up in another and that journey is very dangerous because it changes our entire neuromuscular coordination system the changes begin in the early year of life and continue as we grow as we get older because we have a larynx all the way down in the throat our airway and our food way which were separate in babies and which were separate in a monkey or a dog are now crossed and this is very dangerous and this is one of the reasons we always get food stuck in our throat when we're trying to eat and it's also one of the reasons why we have food that regurgitates so we've lost out but we gain something by the larynx going all the down in the throat we get a large area of space above it which can take the sounds that are produced inside the larynx at what we call the vocal cords or vocal folds and we can modify them to a greater extent than that possible for any other mammal we have thus gained the ability for fully articulate speech the two species had their larynx at different levels the Neanderthal is on the left modern humans on the right the flatness of their skull base tells us their larynx would be up much higher and that their overall vocal tract would be very different than that which you find in living human beings this tells us that the an Turtles could not speak the way we speak today when the larynx is in a high position the distance from the mouth to the vocal tract is short we let our voices resonate in the vocal tract with a short vocal tract Neanderthals would be limited the general ambience would be different according to some linguists they probably couldn't make certain of what we call the quantum vowel sounds the ones we call in English ooh-aah e the sounds in boot father or feet it's highly unlikely that Neanderthals could make them and with the same speed that we do the hallmark of our kind is our ability to have fully articulate speech this is what sets us apart from all other animals and this is what set us apart from the an Turtles modern science now has the technology to investigate down to the molecular level dr. Simon Fisher and Cecilia Lai of the Wellcome Trust Centre in England have identified a gene that is involved with speech it's called fox p2 and is attached to the human chromosome number seven they think this gene evolved more recently than two hundred thousand years which would suggest that fox p2 appeared after we had evolved it might have improved brain functions that are used for language skills but we don't know as yet we think that Fox b2 is a very exciting discovery because it clearly has had a dramatic impact on human speech and language abilities but it's important to realize that this is just one piece of a bigger puzzle but the great thing is that we now have a tool we can use Fox b2 to find other elements of the pathway and of the puzzle 40,000 years ago Europe was experiencing the last peak of an ice age in the North the glaciers expanded and covered that part of the continent in those conditions perhaps it was language skills which gave us the edge over the Neanderthals we would have been able to share information about the large migrating herd so we could plan ahead for the Hunts and would be able to record the information we have gathered it's thought that the marks on this bone might be a calendar of sorts it was made by modern humans 35,000 years ago we had started on a path that no other species have followed these paintings on the walls of a cave in France show our ability to picture the world around us we not only spoke a complex language we began to transmit knowledge to future generations the essential difference between the Neanderthals and the kromagg nose appears to have been one of symbolic ability the Neanderthals left behind themselves a very rich record of their material lives but that record doesn't really contain much if anything at all that suggests a symbolic kind of existence whereas the lives of the cro-magnons were literally drenched in symbol the chrome anions were us they had all of those characteristics that we prized in themselves in ourselves today they had painting they painted fantastic art on the walls of caves they did sculpture they did engraving they had music they had musical instruments they had notation they had symbolic behaviors of all of the kinds that we associate with ourselves today indeed we have come a long way from those fires our distant ancestors lit in the African night dr. Ian Tattersall of the American Museum of Natural History believes it was complex language that allowed the development of symbolic thought the communication of ideas and beliefs language is more or less nowadays inextricable from our symbolic mental processes that allow us to understand the world in unprecedented ways and ask questions like you know what if we can pose questions like that and experiment with ways of dealing with the world and of exploiting the world in a more efficient way and that is what I think sort of made Homo sapiens a unbeatable competitor when they came on the scene and what ultimately led to the Demi's of the Neanderthals 30,000 years ago the fate of the two human species Homo sapiens and Neanderthals came to a crossroads complex verbal communication allowed Homo sapiens to share thoughts and ideas to cooperate in a search for food and the struggle for existence it was a struggle that the Neanderthals would lose and there would be only one species left on the miracle planet in rural area in southwestern France lies one of the last Neanderthal sites immediately above the Neanderthal remains are those of Homo sapiens perhaps Neanderthals were driven away from their former habitat by the more capable modern humans or perhaps the Neanderthals quietly left on their own whatever 30,000 years ago they died out we became the last survivors for the past four billion years the pace seems to have picked up perhaps on mastery of language is taking us toward a new and faster process of evolution I think it is a fascinating point that language is a kind of second genetics genetics itself lasted for the first four billion years of life's history and then quite suddenly Darwinian evolution genetic evolution gave rise to creatures with big brains which developed a second kind of genetics which is language and the transmission of linguistic information down through generations that gave rise to a second kind of evolution which is called cultural evolution which looks like genetic evolution in a superficial sense but its enormous ly faster and our lives have become faster we live in an age when technology moves at a pace that perhaps we cannot stop our ability to communicate as at times transcended the message we are trying to send what took decades now can be achieved in less than a year and as each year passes the pace increases as a species we now can influence the climate just as microbes did in the early history of the earth we must learn the history of our planet which has nurtured life for billions of years dr. Noam Chomsky knows that the choice for the future is ultimately ours this is a question of history not evolution and it's a question of culture and intelligence and sympathy and understanding understanding and mutual aid and support and so on those are capacities that we have we know from our own history and experience that those capacities can be overwhelmed by other more destructive savage and cruel capacities that we also have and the balance of these will determine whether the species survives in any decent form and that's a matter of will and choice there are no natural laws about this as a species we are still held captive by the only planet we know that can support life science shows us that life was nurtured in the oceans of this planet soon after its birth and that it matured through long ages of change finally it spread out across the world diversified into myriad forms most of which would trade away to become only a memory after millions of years a single species was to be the pervading force but that could change in the blink of an eye if we have learnt anything at all from our history it must be that in the end life prevails and ultimately will be the victor on the miracle planet
