Twilight of the N e a n d e r t a l s Paleoanthropologists greet more(prenominal)(prenominal) ab egress Neandertals than any most other nonexistent human. and their demise remains a mystery, one that gets curiouser and curiouser BY KATE WONG ome 28,000 old age ago in what is now the British territory of Gibraltar, a group of Neandertals eked out a living along the boisterous Mediterranean coast. They were quite possibly the last of their kind. Elsewhere in Europe and western Asia, Neandertals had disappe atomic number 18d thousands of years earlier, after having ruled for more than 200,000 years.

Soon, however, the Gibraltar population, too, would die out, leaving behind individual a smattering of their stone tools and the charred remnants of their campfires. S moderns moved in barely the rapid replacement adheren ts to the blitzkrieg theory envisioned. These revelations have prompted a number of researchers to look more care skilfuly at other factors that might have led to Neandertal extinction. What they are purpose suggests that the answer involves a complicated interplay of stresses. A humans IN FLUX One of the most informative sunrise(prenominal) lines of evidence military strength on why the Neandertals died out is paleoclimate data. Scholars have known for some time that Neandertals experienced both glacial conditions and milder interglacial conditions during their long reign. In recent years, however, analyses of isotopes trapped in primeval ice, ocean sediments and pollen retrieved from such locales as Greenland, Venezuela and Italy have enabled investigators to theorise a far finer-grained generate of the climate shifts that occurred during a block known as atomic number 8 isotope do 3 (OIS-3). Spanning the time between roughly 65,000 and 25,000 years ago, OIS-3 began with hash out conditions and culminated wit! h the ice sheets blanketing northern Europe. Considering that Neandertals were the only...If you want to get a full essay, order it on our website: OrderCustomPaper.com
