Humans First Arose in Asia?
IZ Reloaded writes "Two archaeologists are proposing the idea that early humans first arose in Asia instead of Africa as previously thought. These early humans then migrate out of Asia to parts of the world. From National Geographic: 'The unresolved status of the intriguing Flores finds attributed to H. floresiensis leaves open the possibility that this species is the end result and last survivor of an ancient migration of very primitive humans, or even prehumans, that formerly existed more widely across Asia ... '"
We have tons of data points showing homo sapiens evolved in Africa. So many of the missing links like Lucy and other members of the homo tree have all been found in Africa.
I'm not debating their points (I've not read the article yet), but it would seem to require us to throw out the data that we already have. If homo species migrated to the rest of the world from Asia, then it would have requires Lucy, a relatively primitive human to have gotten to Africa, then start a long series of descendents and multiple branches of evolution there, eventually resulting in homo sapiens.
I am unamerican, and proud of it!
You can find that almost anywhere. Like here - browse at -1, for example.
You feel that beeing releated to Slashdotter regulars is an improvement?
Amazing, even human evolution is getting outsourced to Asia!

Ah yes, but religion is so CONVENIENT. It means that often the believer needs to make no personal moral decisions (your religion makes absolute moral decisions for you), and everyone's split into two camps: People that are going to Heaven (usually believers) and people that are going to Hell (usually everyone else). Often the sheer convenience and lifelong training in a religion overrides a personal quest for scientific truth.
Furthurmore, in times where science would say to you "Hey man, you're 100% screwed!" religion can give a more optimistic answer. It's easy to decry religion when you're sitting in front of your LCD or CRT, but it's can give hope to the otherwise hopeless if they think that an all-powerful, all-knowing being is watching over their backs ready to send them to paradise when they die.
I have no problem with religion whatsoever. However, I think that religion should stay in churches (for example) and science should stay in schools, universities, etc. Everything has its time and place.

Wouldn't it be possible that pre-humans migrated to different locations and finished their evolution separately? Considering Neandrathals are no longer considered in a direct evolutionary line to modern humans, that indicates a separate branch of evolution.
Distinctly different environments, like Asia and Africa, could account for something like this. Multiple evolutionary paths, occurring in multiple physical locations on the planet. Why do scientists seem so attached to the "Eve" theory?

Learning HOW to think is more important than learning WHAT to think.
Evil Lord Xenu froze all the alien races and dumped them into volcanoes here on earth. Their souls were collected by soul vacuumes and then forced to watch movies and be brainwashed, only to then inhabit the bodies of primitive man. I think that's how it goes, I still have to pay for a few more audit councelings before my thetan levels are capable of truly grasping this profound knowledge
So an early asian humanoid and a early african humanoid walk into a bar...

I dunno about western culture. Here in the Northwest region of America, every block there is either Indian, Sushi, Thai, Teriyaki or Chinese food. If you watch movies like the Matrix, you see Asian influenced martial arts. If you play video games you are most likely playing a Nintendo or a Playstation. If you watch cartoons, you are most likely watching a Japanese animated story.
It's a myth that the Chinese didn't use gun powder as weapons. In fact they did. In fact the idea of a Chinese person is also a myth. It's like the myth of an American person. That's why they are successful. They were one of the first places that took disparate groups and held it under one rule as one people, even though quite a few of the inhabitants spoke different languages and were of differerent "races". You might argue that the Romans did that as well, but they failed to hold on to it.
The article talks quite a bit about fossil evidence, but what about the genetic evidence? If you look at the variability of human genetics, you find that europeans aren't very genetically diverse. Similarly, American Indians aren't very genetically diverse, and Asians aren't either. Africans, on the other hand, are very genetically diverse. What this indicates is that the human race' history in Africa goes back much further than anywhere else. It appears that a subset of Africans left Africa and colonized the rest of the world. Here's a short article that talks about human genetic diversity compared to their location: http://info.med.yale.edu/genetics/kkidd/point.html

The problem has always been that there are two sorts of strong evidence: humans are almost all alike, and humans evolved in place. (E.g. early Australians were H. erectus; later they had mixed erectus and sap. characteristics; eventually the erectus features faded and vanished, leaving pure H. sap.) Naturally each had adherents who preferred to discount the others' evidence. The two have certainly seemed contradictory, up until now.
They were both right. What spread out of Africa was not actual populations of H. sap. etc., supplanting H. erectus populations that preceded them. Rather, successful gene complexes that define H. sap. spread out of Africa, upgrading local populations in-place. (Think of them as software patches.) Hardly anybody had to migrate any farther than the next village over. People married into neighboring villages, bringing their genetic advances with them, and the next generation brought them to the next village along. Of course successful genes could spread back to Africa, too, but Africa had the most variation, so produced more of the successful genes, and packaged them with more other, complementary genes.
Contrast this with the spread of agriculture into Europe, where there's evidence of farmers actually supplanting hunter/gatherers; and of course the historical record, with wholesale slaughters and genocides. (No doubt there was plenty of slaughtering earlier, but it takes technology, language, and civilized infantilization for genocides to be conducted efficiently.)
It doesn't seem like there are many other species in which this process would have worked. Bears, maybe.
