What did prehistoric hominid eat?
In an unusual intersection of materials science and anthropology, scientists from the National Institute of Standards and Technology (NIST) and The George Washington University (GWU) have applied materials-science-based mathematical models to help shed light on the dietary habits of some of mankinds prehistoric relatives. Their work forms part of a newly published, multidisciplinary analysis* of the early hominid Australopithecus africanus by anthropologists at the State University of New York at Albany and elsewhere........

First Americans arrived as 2 separate migrations
The first people to arrive in America traveled as at least two separate groups to arrive in their new home at about the same time, as per new genetic evidence published online on January 8th in Current Biology, a Cell Press publication. After the Last Glacial Maximum some 15, 000 to 17, 000 years ago, one group entered North America from Beringia following the ice-free Pacific coastline, while another traversed an open land corridor between two ice sheets to arrive directly into the region east of the Rocky Mountains. (Beringia is the landmass that connected northeast Siberia to Alaska during the last ice age.) Those first Americans later gave rise to almost all modern Native American groups of North, Central, and South America, with the important exceptions of the Na-Dene and the Eskimos-Aleuts of northern North America, the scientists said........

Oetzi's last supper
What we eat can say a lot about us - where we live, how we live and eventually even when we lived. From the analysis of the intestinal contents of the 5, 200-year-old Iceman from the Eastern Alps, Professor James Dickson from the University of Glasgow in the UK and his team have shed some light on the mummy's lifestyle and some of the events leading up to his death. By identifying six different mosses in his alimentary tract, they suggest that the Iceman may have travelled, injured himself and dressed his wounds. Their findings1 are reported in the recent issue of Springer's journal Vegetation History and Archaeobotany, which is specially dedicated to Oetzi the Iceman........
