British scientists have eliminated one potential explanation for the Neanderthals' extinction 26,000 to 32,000 years ago. Using a core sample of ocean sediment drilled from Venezuela's Cariaco Basin, researchers from the University of Leeds concluded that there were no significant changes in climate during the period. That leaves elimination of the Neanderthals by modern humans as the most likely explanation, they reported Thursday in the journal Nature.

Using a 38,000-year-old bone fragment found in a Croatian cave, scientists have decoded a section of DNA from humanity's closest related species -- the long-extinct and enigmatic Neanderthal. The reports, published concurrently today in the journals Nature and Science, demonstrate the feasibility of squeezing genetic information out of fossils -- a new way of probing the ancient past that until now has been glimpsed primarily through scattered bones and artifacts.

Neanderthals survived for thousands of years longer than scientists thought, with small bands finding refuge in a massive cave near the southern tip of Spain, new research suggests. The work contends that Neanderthals were using a cave in Gibraltar at least 2,000 years later than their presence had been firmly documented anywhere before, researchers said.

A two-year project has been launched to decipher the genetic code of the Neanderthal. Scientists from Germany's Max Planck Institute for Evolutionary Anthropology and 454 Life Sciences Corp. of Branford, Conn., will reconstruct a draft of the 3 billion building blocks of the Neanderthal genome, working with fossil samples from several individuals. The Neanderthal species lived in Europe and western Asia from more than 200,000 years ago to about 30,000 years ago.

The ancestors of modern humans moved into and across Europe, ousting the Neanderthals faster than previously thought, a new analysis of radiocarbon data shows. Rather than taking 7,000 years to colonize Europe from Africa, the reinterpreted data indicated the process might have taken 5,000 years, Paul Mellars, a professor of prehistory at Cambridge University, said in the current issue of the journal Nature.

Researchers have sequenced the DNA of two extinct cave bears and say their method is accurate enough to try on extinct humans such as Neanderthals, according to a report published Thursday. The cave bears are the first extinct animals to have their genes sequenced, and the findings can be used to determine the precise relationship between the 40,000-year-old bears and living species.
