In an article published in the open-access, peer-reviewed journal PLoS ONE on October 21, 2009, Dr Thomas Plummer of Queens College at the City University of New York, Dr Richard Potts of the Smithsonian Institution National Museum of Natural History and colleagues report the oldest archeological evidence of early human activities in a grassland environment, dating to 2 million years ago. The article highlights new research and its implications concerning the environments in which human ancestors evolved. http://www.physorg.com/news175330627.html Other Sciences Wed, 21 Oct 2009 08:20:01 EST news175330627 (PhysOrg.com) -- Archaeologists have used stone tools to answer many questions about human ancestors in both the distant and near past and now they are analyzing the origin of obsidian flakes to better understand how people settled and interacted in the inhospitable Kuril Islands. http://www.physorg.com/news164896641.html Other Sciences Mon, 22 Jun 2009 13:37:55 EST news164896641 (PhysOrg.com) -- A new dating method has found that "Peking Man" is around 200,000 years older than previously thought, suggesting he somehow adapted to the cold of a mild glacial period. http://www.physorg.com/news156001133.html Other Sciences Wed, 11 Mar 2009 14:39:52 EST news156001133 Dazzling new scientific techniques are allowing archaeologists to track the movements and menus of extinct hominids through the seasons and years as they ate their way across the African landscape, helping to illuminate the evolution of human diets. http://www.physorg.com/news153674920.html Other Sciences Thu, 12 Feb 2009 15:29:29 EST news153674920 There are two species of lice that infest humans: pubic lice, Pthirus pubis, and human head and body lice, Pediculus humanus. A new article in BioMed Central's open access Journal of Biology suggests one explanation for the separation of the two species. http://www.physorg.com/news153570083.html Biology Wed, 11 Feb 2009 10:28:24 EST news153570083 A research team led by Professor Michael Chazan, director of the University of Toronto's Archaeology Centre, has discovered the earliest evidence of our cave-dwelling human ancestors at the Wonderwerk Cave in South Africa. http://www.physorg.com/news148919004.html Other Sciences Fri, 19 Dec 2008 14:23:24 EST news148919004 (PhysOrg.com) -- It was a dirty job, but somebody had to do it. Anthropologist Nathaniel J. Dominy of the University of California, Santa Cruz, has advanced the investigation of the diet of early human ancestors by painstakingly measuring the mechanical properties of the underground parts of nearly 100 plant species across sub-Saharan Africa. http://www.physorg.com/news138466447.html Other Sciences Wed, 20 Aug 2008 15:54:07 EST news138466447 (PhysOrg.com) -- It was a dirty job, but somebody had to do it.
