Diet, population size and the spread of modern humans into EuropeAugust 11, 2009Accumulating carbon and nitrogen stable isotope data from fossil humans in Europe is pointing towards a significant shift in the range of animal resources exploited with the spread of modern humans into Europe 40,000 years ago. Both the preceding Neandertals and the incoming modern humans regularly and successfully hunted large game such as deer, cattle and horses, as well as occasionally killing larger or more dangerous animals. There is little evidence for the regular eating of fish by the Neandertals. However, the stable isotope data published this week in the Proceedings of the National Academy of Sciences by Erik Trinkaus, professor of anthropology at Washington University in St. Louis, and Michael Richards of the University of British Columbia and the Max Planck Institute, suggests that at least some of the European early modern humans consistently consumed fish, supplementing their diet of terrestrial animals. It is likely that this greater emphasis on small, harder to obtain, sources of protein reflects growing human populations in Europe and the pressure they placed on their environments.

First direct evidence of substantial fish consumption by early modern humans in China Freshwater fish are an important part of the diet of many peoples around the world, but it has been unclear when fish became an important part of the year-round diet for early humans. New analysis shows 'hobbits' couldn't hustle A detailed analysis of the feet of Homo floresiensis-the miniature hominins who lived on a remote island in eastern Indonesia until 18,000 years ago-may help settle a question hotly debated among paleontologists: how similar was this population to modern humans?

Understanding Extinct Microbes May Influence the State of Modern Human Health The study of ancient microbes may not seem consequential, but such pioneering research at the University of Oklahoma has implications for the state of modern human health. Cecil Lewis, assistant professor in the Department of Anthropology, says results of this research raise questions about the microbes living on and within people. Common food additive found to increase risk and speed spread of lung cancer New research in an animal model suggests that a diet high in inorganic phosphates, which are found in a variety of processed foods including meats, cheeses, beverages, and bakery products, might speed growth of lung cancer tumors and may even contribute to the development of those tumors in individuals predisposed to the disease. Study shows competition, not climate change, led to Neanderthal extinction In a recently conducted study, a multidisciplinary French-American research team with expertise in archaeology, past climates, and ecology reported that Neanderthal extinction was principally a result of competition with Cro-Magnon populations, rather than the consequences of climate change. 'Hobbit' fossils represent a new species, concludes University of Minnesota anthropologist University of Minnesota anthropology professor Kieran McNulty (along with colleague Karen Baab of Stony Brook University in New York) has made an important contribution toward solving one of the greatest paleoanthropological mysteries in recent history -- that fossilized skeletons resembling a mythical "hobbit" creature represent an entirely new species in humanity's evolutionary chain. New evidence of battle between humans and ancient virus For millennia, humans and viruses have been locked in an evolutionary back-and-forth -- one changes to outsmart the other, prompting the second to change and outsmart the first. Methane Release Could Cause Abrupt, Far-Reaching Climate Change An abrupt release of methane, a powerful greenhouse gas, from ice sheets that extended to Earth's low latitudes some 635 million years ago caused a dramatic shift in climate, scientists funded by the National Science Foundation (NSF) report in this week's issue of the journal Nature.
