The Perennial Plate | Adventurous and Sustainable Eating FedStats Scientists provide a more accurate age for the El Sidrón cave Neanderthals -- ScienceDaily A study has been able to accurately determine the age of the Neanderthal remains found in the El Sidrón cave (Asturias, Spain) for which previous studies had provided inexact measurements. The application of a pre-treatment to reduce contamination by modern carbon has managed to lower the margin of error from 40,000 to just 3,200 years. El Sidrón cave in Asturias (northern Spain) is one of the westernmost Neanderthal sites on the Iberian Peninsula and contains a large amount of this type of remains in addition to the flint tools they used. Now, thanks to the development of new analytical procedures, a research team co-ordinated by the University of Oviedo (Spain) has managed to provide a more accurate dating for these Neanderthal populations in Asturias. The age of the El Sidrón remains could prove to be an important piece of information in the discussion about when the transition from Neanderthal to Homo sapiens took place in Europe.
Find answers to your medical questions with these five sites | Webware I am, sadly, well-acquainted with medical research sites. (I broke my back years ago, and am still dealing with the recovery.) But while everyone knows WebMD and probably uses the site to find out about medical conditions, you might be surprised to know there are a slew of sites that offer similar service, providing outstanding medical information. I've found these sites to be good resources. HealthiNation While some sites deliver articles of medical information, HealthiNation uses videos to inform you about what a condition is all about. Overall, HealthiNation is designed quite well and its easy to search for videos. HealthiNation's videos are split into general health, men's health, women's health, and "true life stories," which detail how one person faced medical conditions in their lives. The videos on HealthiNation were outstanding. Livestrong The first thing that will strike you about Livestrong is its almost unbearable design. WebMD The real value of WebMD is seen in its search.
Welcome to Survivor Jane lawcrawler.findlaw Separation between Neanderthal and Homo sapiens might have occurred 500,000 years earlier, DNA from teeth suggests The separation of Neanderthal and Homo sapiens might have occurred at least one million years ago, more than 500.000 years earlier than previously believed, according to new DNA-based analyses. A doctoral thesis conducted at the National Center for Research on Human Evolution (Centro Nacional de Investigación sobre la Evolución Humana), associated with the University of Granada, analyzed the teeth of almost all species of hominids that have existed during the past 4 million years. Quantitative methods were employed, and they managed to identify Neanderthal features in ancient European populations. The main purpose of this research, whose author is Aida Gómez Robles, was to reconstruct the history of evolution of the human species using the information provided by the teeth, which are the most numerous and best preserved remains of the fossil record. To this purpose, a large sample of dental fossils from different sites in Africa, Asia and Europe was analyzed. Computer Simulation

Discovery Reveals That Neanderthals Were the First in Europe to Make Specialized Bone Tools Four views of the most complete lissoir found during excavations at the Neanderthal site of Abri Peyrony. Credit: Abri Peyrony & Pech-de-l’Azé I Projects A new discovery in southwest France reveals that Neanderthals were the first in Europe to make standardized and specialized bone tools. Two research teams from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the University of Leiden in the Netherlands have jointly reported the discovery of Neanderthal bone tools coming from their excavations at two neighboring Paleolithic sites in southwest France. Modern humans replaced Neanderthals in Europe about 40 thousand years ago, but the Neanderthals’ capabilities are still greatly debated. “If Neanderthals developed this type of bone tool on their own, it is possible that modern humans then acquired this technology from Neanderthals. How widespread this new Neanderthal behavior was is a question that remains. Shannon P. Source: Max Planck Institute
