The Humans Who Went Extinct: Why Neanderthals died out and we survivedThis is the best publication I have read on the subject for years in an excellent hard cover publication. An original perspective on early Ice Age humans and their Neanderthal cousins and some quite innovative ideas on why we survived the intolerable Ice age conditions in Eurasia between 20000 to 50000 years ago and possibly why the Neanderthal, a better adapted human for the conditions, didnt. What I liked best was the Jared Diamond style perspective of looking at the human creature from a biological or even Zoological viewpoint without the natural biases regarding the perceived intellectual superiority of modern humans. There is no suggestion here that we had some superiority advantage over our cousins. Rather that good fortune and opportunism gave modern humans an advantage that could have just as easily benefitted Neanderthals, had their circumstances permitted.
I would strongly suggest to anyone wanting to expand their awareness of these poorly understood and under rated people to have a look at this one. Its worth the journey.

An addendum September 2011 given recent discoveries:
Having read some other reviews there is still I believe this concept of superiority many of us have of the modern human creature. I would suggest reading some of Jared Diamonds works to gain balance
The Neandertal people, though genetically different in some ways, suffered as I see it, a similar plight to the Australian Aboriginal people. Just as intelligent as other peoples in Europe, Asia and Africa, these people became somewhat isolated and had to adapt with the technology they brought with them 50-60000 years ago (though some came later) to unfamiliar and hostile environments, just as the Neandertal had to in Eurasia.
As with the Australian Aboriginal, their adaption to a hostile environment with the technology they had, led a serious reduction in population per area of ground to survive. And they apparently adapted very well to the environment they inherited over time. But just as the Australian Aborigine was restricted by a limited population, lack of agricultural plant life and beasts of burden, seriously diminished any technological advancements, the Neandertal's faced similar types of limitations, other humans did not have to cope with, in their extreme conditions. When the Europeans came to Australia, as with the humans to Ice Age Euarasia, they came better prepared through tens of thousands of years of cultural development and improved technology.
Europeans and Asians have had the advantage of exchange of ideas over the Eurasian continent during the Holocene, as well as agricultural foods and beasts of burden and therefore a greater population per area of ground. This has allowed significant technological advancement. Therefore when Europeans came to Australia to settle, the indigenous population were overwhelmed by a superior technology, a continuous influx of migration and of course new diseases that decimated the existing population.
A parallel surely exists with the influx of a technologically advanced African humanity into Eurasia 40-50000 years ago. Though they had to also adapt to the new conditions they had developped culturally and technologically in such a manner that they were eventually better able to survive and flourish. Just as with the Australian Aboriginal, the Neandertal could not compete and found their feeding grounds increasingly encroached upon by a more numerous and technologically more sophisticated people.
But the caveat here is that, as with the Austraian Aborigine, it was not intelligence that was lacking and led to the Neandertal's disappearance, but rather isolation from the greater numbers of humans, who had had greater opportunity to develop their technology. And as is evident now, just as with the Australian Aborigine, they didnt disappear, they merely became absorbed within the migrant population through intermarriage and interbreeding.
