I suggest you guys view the "Journey of Man" in You Tube or download to watch it...then a lot of ideas would connect properly....
Okay, ya talked me into it. I just watched all 13 segments on YouTube.
Very nicely done. On a par with the series by James Burke, Joseph Campbell and David Attenborough. Some very moving scenes. He kept encountering people with strong mythologies who couldn't relate to his scientific explanation of their origin. But then he handed those photos of the Chukchi to the Navajo family and they started seeing the faces of their friends and relatives. That was really sweet.
The research is certainly definitive for migration patterns and ethnic relationships. It shakes up some old theories, but doesn't actually knock most of them down. For the most part it fills in some gaps, straightens out some wrinkles and explains some anomalies, No one's had a really solid picture of the migration of the Australians before and this finally settles the question. It explains the isolation of the Chinese and the strangely slow pace of human migration into Europe. Finally we see that there were two major waves of migration out of Africa, which makes sense out of the apparent boundary between two peoples in India.
It wasn't long enough to go into some of the details I was looking for. About 25 years ago, before DNA analysis was affordable, a team of a dentist, a doctor and a linguist looked at the dental patterns, blood types and languages of the Americas and determined that there had been three waves of migration from Siberia in 14000, 6000 and 4000BCE, but they all started in very nearly the same place in central Asia. I was hoping to see if that theory had been discarded but they didn't have time for everything.
I also thought there was a bit of deliberate editing that heightened the sense of mystery only so he could be the hero who solved it. He made it clear early on that the coastlines in 50,000BCE were 25 miles further out than they are today. But then when he started looking for evidence of the coastal migration from Africa to Australia, he took his sweet time before slapping his forehead and saying, "But of course, dear viewers, I'm forgetting that the evidence would now be under water, 25 miles out to sea!" Cheap shot, dude!
But what I did not see was any groundbreaking work in linguistics. Cavalli-Sforza's theories are controversial, to put it charitably, and many linguists bluntly say they're outdated. We have to greatly downplay the role of linguistic analysis in the tracing of human relationships because we've had to accept the fact that human migration is not necessarily the primary engine of the spread of language. After all, by using linguistics alone we'd assume that the Bulgars were a Slavic people, the Cherokees are Anglo-Saxon, the French are Italic, the Galician Jews are Germanic, but the Jews of Jesus's time were Aramaeans. Fifty years ago my teachers were already reminding us that language follows the coin, not the flag.
What I really found weak and more than a bit fanciful were his strong opinions about the origin of language. We linguists would love to prove that language was indeed the technology that allowed humanity to advance to new heights of accomplishment and sophistication, but we don't find the evidence persuasive. As a musician I know that for some of us there are major parts of our life that we think about
non-verbally. I don't think that wood carvers form their thoughts in sentences when they're deciding how to turn a lovely vein of woodgrain into a focal point of a statue, and I don't think that people who are designing bows and arrows necessarily have to form words in order to have sophisticated ideas about shapes and materials and vectors. After all, cats can solve equations in three-dimensional kinematics and I'm positive they do it without words.
I didn't see any evidence that humans could recognize footprints as evidence of the proximity of prey animals only after they developed language. I didn't see any evidence that the click language had to be the first one and all other languages lost the clicks. As I noted before, it's just as plausible that the hunters discovered that a communication code based on clicks could be used without alerting the prey to their presence, and they either built a language around them or worked them into an existing language, and no other people happened to stumble onto that device.
I got the impression that he thinks language sprang up rather quickly. Considering how slowly languages evolve once they're established, it seems implausible that an entire language could be created from scratch in just a few generations. Considering that language by definition is made up of sounds, it's impossible that the neighboring tribes would not be curious about all the weird noises and borrow the idea once they caught on. I do not believe that one tribe could develop language and suddenly out-compete everyone else, any more than they were able to do that with other paradigm-shifting technologies like farming, animal husbandry or ironworking. Humans are fast learners and it's hard to keep a good idea secret from your neighbors.
I definitely find you folks' ideas about three ancestral languages more than a little fanciful.
Wells's earnest arguments notwithstanding, we really do not have convincing evidence that the technology of language was invented more than about 15,000 years ago. We really do not have convincing evidence of the Nostratus Superfamily hypothesis that all non-African languages are descended from a common ancestor. What we have is a couple of dozen language families (and my count may be off) that we cannot say for certain are related at all. Chinese, Arabic and Tamil, for example, are so different in every way that it's difficult to even find a place to start looking for relationships.
Supercomputers have found a core set of about fifty words--good solid words like body parts, numbers and pronouns that are usually stable--that appear to be shared by all major languages... IF you accept the phonetic shift paradigms that make them line up. The problem with this is that with only fifty words it could still easily be one enormous coincidence and the paradigm was the creation of a really smart computer, not a real phenomenon.
And nobody is even talking about where the other African languages came from or how old they are!
