Study points to larger role of Asian ancestors in evolution Mon Aug 6, 9:59 PM ET
CHICAGO (AFP) - A new analysis of the dental fossils of human ancestors suggests that Asian populations played a larger role than Africans in colonizing Europe millions of years ago, said a study released Monday.
The findings challenge the prevailing "Out of Africa" theory, which holds that anatomically modern man first arose from one point in Africa and fanned out to conquer the globe, and bolsters the notion that Homo sapiens evolved from different populations in different parts of the globe.
The "Out of Africa" scenario has been underpinned since 1987 by genetic studies based mainly on the rate of mutations in mitochondrial DNA, a cell material inherited from the maternal line of ancestry.
But for this study, European researchers opted to study the tooth fossil record of modern man's ancestors because of their high component of genetic expression.
The investigators examined the shapes of more than 5,000 teeth from human ancestors from Africa, Asia and Europe dating back millions of years.
They found that European teeth had more Asian features than African ones.
They also noted that the continuity of the Eurasian dental pattern from the Early Pleistocene until the appearance of Upper Pleistocene Neanderthals suggests that the evolutionary courses of the Eurasian and African continents were relatively independent for a long period.
"The history of human populations in Eurasia may not have been the result of a few high-impact replacement waves of dispersals from Africa, but a much more complex puzzle of dispersals and contacts among populations within and outside continents," the researchers wrote.
"In the light of these results, we propose that Asia has played an important role in the colonization of Europe, and that future studies on this issue are obliged to pay serious attention to the 'unknown' continent."
The paper was written by researchers at Spain's national center for research into human evolution in Burgos and appears in the journal of the Proceedings of the National Academy of Sciences. |

I don't doubt it, but then again, Asian evolution is obviously able to be traced back to Africa. I see little point in this thread, as it's not very interesting. But all the power to you, I have posted some pretty boring computer threads a couple of times (well, others thought they were boring at least  ). |

(Dude, hundreds of millions of of 'Asians' are Caucasians, Dravidians, Australoids, etc. and have NOTHING at all to do with Korea.)

Why are you making a point in highlighting only Asian Men in the thread's title? There was no mention of one sex over the other in the article -- why are you trying to claim that women had no part in these claims?

I fail to see the connection. Even in the "Out of Africa" theory it was assumed that populations migrated from Africa to Europe through Asia. Without reading the report ($10 for two days of access) it's hard to say what the evidence actually supports and what's simply meaningless gloss supplied by Yahoo News. I'm calling malarky on this one. |

You do realize that Asian is a prett damn big continent just another day?
But I did always wonder if man only evolved on the continent of Africa. Could they have also evolved on other continents?
Anyways, the way I was taught was this:
Man (not homo-sapien man, but an earlier form) first evolved from apes somewhere if the Rift Valley of East Africa.
Then they migrated south (into souther Africa) and north where they eventually crossed into West Asia through the Sinai Pennensula.
Then one group headed east through Arabia, Persia, the Indian subcontinent and eventually into south east Asia, Australia, and East Asia.
Meanwhile the other group headed north and northeast into Caucasis and Central Asia.
These two groups then either headed east to China and Mongolia (and eventually the Americas) or west into Europe. |

Apart from the "Out of Africa" theory (Replacement Hypothesis) there is also the Regional Continuity Hypothesis that suggest that populations of Homo habilis or Homo erectus spread across the continents and independently evolved into Homo sapiens.
This latter theory has been used to validate claims of racial superiority through the understanding that Europeans are derived from Homo (sapiens) neanderthalensis, which had a cranial capacity much larger than modern day humans (the theory being that this makes Europeans smarter than anyone else in the world). It was also used to suggest that the slight brow ridges found in some Australian Aborigines was "proof" of their less advanced intellect due to earlier hominid skulls being found with pronounced brow ridges. Nevermind environmental determinism (that a larger brow size can be beneficial in desert environments) and the fact that not all Aborigines have a brow rige.
Intermediary skeletons have been held up as support for regional continuity but the most well-known of these - the fossil child found at Abrigo do Lagar Velho, Portugal in 1999 - has been discounted from consideration by many anthropologists. (See Tattersall and Schwartz in the Proceedings of the National Academy of Sciences, online at: http://www.pnas.org/cgi/content/full/96/13/7117). Studies in China appear to support the replacement hypothesis as well. Work by Jin Li in 1998 focusing on Y chromosomes has contradicted the regional continuity hypothesis (wikipedia entry for links here: http://en.wikipedia.org/wiki/Jin_Li; PNAS figure showing the migration routes here: http://tinyurl.com/2o7ppj), while further research in 2001 found that all Chinese samples included mutated versions of the M168G gene that has been traced to 79,000 years ago in African populations (link in Chinese here: http://www.people.com.cn/GB/paper81/5250/550425.html).
I am very interested in reading about this new research into early Homo sapiens dentition and what exactly the scientists are trying to measure. As I said earlier, the Yahoo News article is nothing more than gloss with no foundation to it.
For an extra bit of fun involving teeth, early primate fossils show molars with five cusps - often called a Y5 dentition - which is what modern humans have today. Meanwhile, contemporary monkey populations (both New World and Old World) have molars with four cusps and the addition of bilophodont shearing crests (link with diagram: http://tinyurl.com/37wmjj). Human molars are more 'primitive' than monkey molars. Does that mean anything in the greater scheme of things? I'm sure everyone already knows which species has been more successful at populating the planet.  |

I agree with VirginIslander. Some of you on this board really need to chill out. As long as a poster doesn't make extremely rude or inflamatory comments, I don't care what they post. If I think it's boring, I won't post a reply. If I think it's interesting, I will.
In this case of this thread, I wasn't interested in the topic posted by the OP but decided to reply because I think some people on this board take the internet far too seriously. |

Learn about the poster first, you might take that back. Look up their post history, you'll see why. |

LOL i don't think any koreans made it all the way there, altho probably turks, hunnish tribes did.
either way, this must mean neanderthal women were quite attractive. |
