The previously held view of a Europe populated by a stable Neanderthal population for hundreds of thousands of years up until modern humans arrived must therefore be revised.

This new perspective on the Neanderthals comes from a study of ancient DNA published February 25 in //Molecular Biology and Evolution//.

The results indicate that most Neanderthals in Europe died off as early as 50,000 years ago. After that, a small group of Neanderthals recolonised central and western Europe, where they survived for another 10,000 years before modern humans entered the picture. The study is the result of an international project led by Swedish and Spanish researchers in Uppsala, Stockholm and Madrid.

“The fact that Neanderthals in Europe were nearly extinct, but then recovered, and that all this took place long before they came into contact with modern humans came as a complete surprise to us. This indicates that the Neanderthals may have been more sensitive to the dramatic climate changes that took place in the last Ice Age than was previously thought”, says Love Dalén, associate professor at the Swedish Museum of Natural History in Stockholm. In connection with work on DNA from Neanderthal fossils in Northern Spain, the researchers noted that the genetic variation among European Neanderthals was extremely limited during the last ten thousand years before the Neanderthals disappeared.
 * Summary: Neanderthals nearly died off 50,000 years ago but recolonised another 10,000 years before modern humans exsisted. **


 * Summary: Neanderthals were more sensitive to dramatic climate changes that took place during the last Ice Age. ((OK)) **

Older European Neanderthal fossils, as well as fossils from Asia, had much greater genetic variation, on par with the amount of variation that might be expected from a species that had been abundant in an area for a long period of time. “The amount of genetic variation in geologically older Neanderthals as well as in Asian Neanderthals was just as great as in modern humans as a species, whereas the variation among later European Neanderthals was not even as high as that of modern humans in Iceland”, says Anders Götherström, associate professor at Uppsala University.

The results presented in the study are based entirely on severely degraded DNA, and the analyses have therefore required both advanced laboratory and computational methods. The research team has involved experts from a number of countries, including statisticians, experts on modern DNA sequencing and paleoanthropologists from Denmark, Spain and the US.
 * Summary: Neanderthal fossils confirm that there was a varation in where they lived. (((Varaition with-in the species???))) **


 * Summary: ?????????????? **

Only when all members of the international research team had reviewed the findings could they feel certain that the available genetic data actually reveals an important and previously unknown part of Neanderthal history. “This type of interdisciplinary study is extremely valuable in advancing research about our evolutionary history. DNA from prehistoric people has led to a number of unexpected findings in recent years, and it will be really exciting to see what further discoveries are made in the coming years”, says Juan Luis Arsuaga, professor of human paleontology at the Universidad Complutense of Madrid.


 * Summary: the reviewed findings reveals an important and perviously unknow part of Neanderthal history. (((Proof read your work))).  **

 * 1. What limited the neanderthals ability to adapt to its environment? Neanderthals were sensitive to dramatic climate change which limited their ability to adapt due to less variation. ((((Awesome))) **
 * 2. Based upon your notes and what Mr. Schraufstetter has taught you, What might have caused Neanderthals to go extinct? The existence of Cro-Mangnon may have caused the Neanderthals to go extinct. (((Good))) **
 * 3. From what you learned, What might have caused the Neanderthals to recover from near extinction within their population? The variation in the recovered Neanderthals could have helped them recover from their near extinction. ** (((Good)))
 * 4. What advantage did older neanderthals in asia and europe have over the most recent neanderthals? The variation in older Neanderthals gave them an advantage. **
 * 5****. What clue about evolution helped scientists determine these findings? The finding of the fossilized remaining pieces of the Neanderthal organism helped scientists determine their theorys. (((DNA also helped))) **
