A research group led by Jakob Christensen-Dalsgaard, University of Southern Denmark, has shown that the closest living relatives of the tetrapods — the lungfish — are insensitive to sound pressure but sensitive to vibrations.

A team of scientists from the NIOZ Royal Netherlands Institute for Sea Research and the University of Bremen (Germany) has determined that a major change in the climate of the Sahara and Sahel region of North Africa facilitated early human migrations from the African continent. The team’s findings will be published online in the Nov. 9th installment of Early Edition of the Proceedings of the National Academy of Sciences USA. Among the key findings are that the Sahara desert and the Sahel were considerably wetter around 9,000, 50,000 and 120,000 years ago than at present, allowing for the growth of trees instead of grasses.

Staff at the University of Leicester Archaeological Services (ULAS) have been excited by the results from a recently excavated major Prehistoric site at Asfordby, near Melton Mowbray, Leicestershire. The Mesolithic site may date from as early as 9000 BC, by which time hunter-gatherers had reoccupied the region after the last ice age. These hunters crossed the land bridge from the continental mainland — ‘Britain’ was only to become an island several thousand years later.

Norwegian scientists have found “mummified” pine trees, dead for nearly 500 years yet without decomposition.

Princeton University scientists have shown that, in ancient times, the Earth’s magnetic field was structured like the two-pole model of today, suggesting that the methods geoscientists use to reconstruct the geography of early land masses on the globe are accurate. The findings may lead to a better understanding of historical continental movement, which relates to changes in climate.

A skeleton, found at one of the most important, but least understood, Roman sites in Britain is puzzling experts from The University of Nottingham.

One of the world’s most famous asteroid craters, the Chicxulub crater, has been the subject of research for about twenty years. The asteroid impact that formed it probably put an end to the dinosaurs and helped mammals to flourish. Together with an Anglo-American team, an ETH Zurich researcher has studied the most recent deposits that filled the crater. The results provide accurate dating of the limestones and a valuable basis for archaeologists to research the Maya.

For the past 2 million years, the size of the human brain has tripled, growing much faster than other mammals. Examining the reasons for human brain expansion, University of Missouri researchers studied three common hypotheses for brain growth: climate change, ecological demands and social competition. The team found that social competition is the major cause of increased cranial capacity.

Research which finally proves that bones found in Shropshire, England provide the most geologically recent evidence of woolly mammoths in North Western Europe publishes June 17 in the Geological Journal. Analysis of both the bones and the surrounding environment suggests that some mammoths remained part of British wildlife long after they are conventionally believed to have become extinct.
