Ice Age Extinction Claimed Highly Carnivorous Alaskan Wolves (6/27/2007)The extinction of many large mammals at the end of the Ice Age may have packed an even bigger punch than scientists have realized. To the list of victims such as woolly mammoths and saber-toothed cats, a Smithsonian-led team of scientists has added one more: a highly carnivorous form of wolf that lived in Alaska, north of the ice sheets. ...> Full Article Ancient DNA Traces The Woolly Mammoth's Disappearance (6/11/2007)Some ancient-DNA evidence has offered new clues to a very cold case: the disappearance of the last woolly mammoths, one of the most iconic of all Ice Age giants, according to a recent article. DNA lifted from the bones, teeth, and tusks of the extinct mammoths revealed a "genetic signature" of a range expansion after the last interglacial period. After the mammoths' migration, the population apparently leveled off, and one of two lineages died out. ...> Full Article Volcano In Siberia Caused The Greatest Mass Extinction Event Of All Time (6/5/2007)Scientists from the Universities of Sheffield and Cambridge have discovered that Mother Nature caused a massive ozone depletion event, some 251 million years ago, during the greatest mass extinction event of all time. ...> Full Article Extraterrestrial Impact Wiped Out Prehistoric Clovis Culture (6/1/2007)Two University of Oregon researchers are on a multi-institutional 26-member team proposing a startling new theory: that an extraterrestrial impact, possibly a comet, set off a 1,000-year-long cold spell and wiped out or fragmented the prehistoric Clovis culture and a variety of animals across North America almost 13,000 years ago. ...> Full Article Ancient Meteor Blast May Have Caused Extinctions (5/26/2007)New scientific findings suggest that a large, extraterrestrial rock may have exploded over North America 13,000 years ago, explaining riddles that scientists have wrestled with for decades, including an abrupt cooling of the atmosphere and the extinction of large mammals. ...> Full Article Reproductive Speed Protects Large Animals From Being Hunted to Extinction (5/17/2007)Understanding the importance of reproductive rates could help conservation managers zero in on which species are in the greatest peril ...> Full Article Climate Change Pushed Neanderthal Into Extinction In Iberian Peninsula (5/4/2007)Climate – and not modern humans – was the cause of the Neanderthal extinction in the Iberian Peninsula. Such is the conclusion of the University of Granada research group RNM 179 - Mineralogy and Geochemistry of sedimentary and metamorphic environments, headed by professor Miguel Ortega Huertas and whose members Francisco José Jiménez Espejo, Francisca Martínez Ruiz and David Gallego Torres work jointly at the department of Mineralogy and Petrology of the University of Granada (Universidad de Granada) and the Andalusian Regional Institute of Earth Sciences (CSIC-UGR). ...> Full Article The Emerging Fate Of The Neanderthals (4/25/2007)
Climate Change Could Make Species Prone To Extinction (4/24/2007)
Role of dinosaur demise in mammal rise challenged (3/31/2007)Scientists have long thought that the mass extinction of the dinosaurs around 65 millions years ago opened the door for modern mammal species to proliferate. But an international team of scientists has created a mammoth record of evolutionary timing, showing that the origins and diversification of existing mammal species - including human ancestors - don’t synch with the demise of the dinosaurs. ...> Full Article |
