mtDNA does evolve rapidly, in fact it evolves in a certain rate. That is why a time frame can be measured out of the devient from two subjects.
In this case, between the Neandertals and Humans, the time frames of the split off in species is 500,000 years.
The point is that different patterns of movement may have caused mitochrondial DNA to diverge more quickly in the past. The whole picture isn't at all clear. The neutrality of modern human mtDNA is a topic hotly debated. If the recent pattern of variation in human populations was a result of a selective sweep in humans, then the mtDNA of Neandertals being "less human" should be expected. It has been discovered that mtDNA is affected by chronic diseases of aging (Zhu X, Smith MA, Perry G, Aliev G. 2004. Mitochondrial failures in Alzheimer’s disease. American Journal of Alzheimers Disease and Other Dementias 19:345-352.), brain disorders (Niemi AK, Moilanen JS, Tanaka M, Hervonen A, Hurme M, Lehtimäki T, Arai Y, Hirose N, Majamaa K. 2005. A combination of three common inherited mitochondrial DNA polymorphisms promotes longevity in Finnish and Japanese subjects 13:166-170.), longetivity (ibid), etc. All these discoveries suggest that mtDNA variation is a strong target for all the above mentioned human changes. These facts suggest that human mtDNA may have undergone multiple adaptive substitutions within the past million years.
The bottom line? The mtDNA study on the "less human" like features of Neandertals or whether or not they are part of the ancestral lineage of Westerners, ie they are homo sapiens, is still unclear and does not kill the argument or is as settled as you may think it to be. The fact is, there is still more research that needs to be done on how mtDNA changes. That Neandertals and homo sapien sapiens coexisted is almost clear, but whether or not they were genetically close enough to mate with homo sapien sapiens is still hotly debated and the current mtDNA analysis does not cut it that they can't mate, simply because we aren't exactly clear on how mtDNA evolved through time. Furthermore, you completely ignored the fossil evidence that I'm sure you would've encountered upon but simply failed to bring it up. Erik Trinkaus discovered a 25,000-year old skeleton from Portugal that shows clear Neandertal traits in a homo sapien sapiens child, a case of a Neandertal-homo sapien hybrid. Most proponents of the opposite theory have simply denied the analysis without any proof. Certain traits, e.g. like huge thigh bones, seem uniquely Neandertal in the child.

When people are talking about human migration in regard to history, the term human, is refering to Homo Saipiens. Not the migration of Homo Erectus or Homo neanderthalensis.
Yes. And whether or not homo neandertalensis did contribute or exactly how much to the ancestral lineage of modern homo sapien sapiens is still hotly debated and that is relevant to the evolution of modern humans. So a study of Neandertals is certainly relevant to the study of modern humans.

In the Y-Chromosome studies, all Eurasian shared this one common father. I am not claiming there is only one human migration, or one human migration into the Far East. In fact I support the view of constant migration into Asia.
Your initial post did not suggest that you supported a "constant migration into Asia". You simply put "DNA studies proved all Far East Asian originated from Iran" like it was only one migration or something, ignoring everything that happened 40,000 years after that. Again, "To claim that the ancestral lineage of East Asians had contributions from Africa may be valid, but to claim that "DNA studies proved all Far East Asian originated from Iran" is an entirely different thing and is far-fetched as well as one-sided and biased because it ignores everything that happened 40,000 years after that, and all the other contributions from other hominid groups, that is local development, which may have contributed as much, if not more, as suggested by newer finds from China and other places."

But my point is the migration into the Far East moved from Central Asia into the Tarim then further Eastward. That is how the Native AMericans got to America. That is how Huang Di moved to the Yellow River area, and that is how Tungus people moved into Siberia.
There is relatively little historical indications that after moving into the Far East, people migrated from South East Asia northward. By the time Indians started to move Eastward along the coast of South East Asia, it was already recorded by history. Even the Austronesians followed the same pattern of North to South, West to East.
Again, that "migration" probably contributed as much to the genetic makeup of those Native Americans as does local development among local populations. The "Out of Africa" theory is just one of the theories and isn't as settled as it once would seem like it was because of newer and newer finds and newer analysis done.
Yet, I still don't understand how any of this gives weight to your argument of Baktria = Yuezhi. Odd logic that you cite something that happened 40,000 years ago when historical research has only traced probable Tocharians to at least 5,000 - 4,000 years ago or so (the Afanasievo that sprung from the Yamnaya). You seem to be oblivious to what happened to human populations and demographic changes in the last 35,000 - 36,000 years before the probable emergence of a distinctly Tocharian people.

You kept claiming proving the relations between Homo Neandertalensis and Homo Saipiens is not your point.
LOL. Because it was not. You seem to have jumped at my conventional grouping of "homo sapien neandertalensis" when I have neither indicated that they were ancestral to homo sapien sapiens nor that they were anatomically the same as modern humans. In fact, that Neandertals and homo sapien sapiens coexisted is almost clear but that Neandertals may have contributed to the genetic makeup of certain populations, ie those of the West, is debatable and only suggests that variations among modern local populations may have been due to different ancestry and that there is no "one wave = all people" as you've suggested with your "Far Eastern Asians originated from Iran" theory.

Likewise my point is that people moved in this direction. And 月氏 and Tocharians might have historically lived in Bactria and still had ties with the area until it was over taken by Seleucids.
Using that logic, I could also deduce that Tocharians lived everywhere between Africa and eastern Central Asia simply because they are humans and migrated east. Why only Baktria? Again, you bringing up what happened 40,000 years ago is irrelevant and also doesn't offer a clue as to what happened to the history of Tocharians, which can only be traced to about c. 4,000 - 5,000 years ago when they, according to some Indo-European experts, diverged from a common ancestor with proto-Celtic and proto-Italic speakers, and made their way across the steppes, NOT the oases to the south of it, ie NOT Baktria, to eastern Central Asia. Historically, Tocharians have been traced to the Afanasievo culture, according to Mallory and Mair.

If Zhang Qian's records are as thorough as it seems, this line is what I am referring to:
康居 is Samarkand, know by the Greek as Marakanda. People in Samarkand speaks Tajik.
Kangju is not Samarkand, but later shifted its center to Samarkand. It was originallly centered in Tashkent. Samarkand is not northwest of Ferghana, but in the heart of Sogdia, which is to the west of Ferghana/Dayuan/Dawan. Refer to the thread about the Five Hu that Yun and I were discussing about.
BTW there are as many people speaking Russian or Uzbek in Samarkand as does Tajik, in fact Uzbek even more since it's the official language as Samarkand is in modern-day Uzbekistan. I don't see your point about Samarkand and Tajiks.

Samarkand is in fact one of the oldest city in the world. By the time Zhang Qian heard of 月氏 fighting with 匈奴 and set off to to establish an allience, till the time he got to 大月氏 was less than 20 years. Yet it is said its customes and 月氏 are 大同俗 (not 大致同俗).
Zhang Qian was captured by the Huns for about 10 years. Let say 20. Then he only took less than a mounth to get to 大宛 Ferghana. From there he probably got to Samarkand in less than a year.
When 月氏 was mentioned, it only said 月氏 is a nomad people just like the Huns (行國,與匈奴同).
The Shi Ji 123 also says something like: "行国也,随畜移徙,与匈奴同俗",or, roughly translated as "They are a nation of nomads, moving from place to place with their herds, and their customs are like those of the Xiongnu." (following Watson) Does that mean that the Xiongnu were Tocharians too? Again, this general designation of "同俗"by Zhang Qian may be a hint as to the generally similar customs and cultures of the steppe nomads. I believe that "同俗" should not be read too indepthly as detail, but rather to hint at the Kangju, Yuezhi, and Xiongnu, as well as the Wusun and the Yancai as steppe nomads sharing similar customs (as in the glorification of their young and despising the old, the generally militant nomadic society, etc.).
QUOTE(naruwan @ Dec 12 2005, 05:51 PM) [snapback]4776102[/snapback]
So in less than 20 years, Samarkand adapted 月氏 customes? or did they share the same customes to begin with?
You've obviously not been keeping up with the discussion on the Five Hu thread. First off Kangju was, as indicated in that thread, centered around Tashkent, not Samarkand, since the Shi Ji 123 says: "康居在大宛西北可二千里", ie 西北 of Dayuan/Dawan/Ferghana, and Samarkand is not northwest of Ferghana, but directly to the west of it. Tashkent is, and, as I've indicated in the Five Hu thread Pulleyblank's linguistic interpretation of Tashkent as "Stone Country/City", and the Kang in Kangju deriving from the kanka of Tocharian, which also means stone, is in line with Tashkent as the center of Kangju.
Second, the Kangju being "行国", ie "walking/moving nation" and "大同俗", ie similar customs, while indicating that they were part of the steppe culture, could also be indicative of their shared Tocharian ancestry with the Yuezhi. In fact, I've already brought this up in the Five Hu thread and their "国小,南羁事月氏,东羁事匈奴" (small country, subservient to the Yuezhi in the south and the Xiongnu in the east) is indicative that they were recent invaders in the southern Kyrgyz steppe and northern Sogdia region and that they were part of the Tocharian peoples who moved to Sogdia along with the Da Yuezhi. This is further collaborated with the Xin Tang Shu 221 that Yun had thankfully provided with the ancestor of Kang being descended from Yuezhi tribesmen who lived in Zhaowu, presumably a city/area in the Junggar Basin. So, the Kangju sharing similar customs with the Da Yuezhi makes sense since they were part of the Tocharian peoples who were forced from the western Gansu - eastern Tianshan region elsewhere, first to the Ili, and then to Baktria.
