An international team of scientists have discovered that climate change played a major role in causing mass extinction of mammals in the late quaternary era, 50,000 years ago. Their study, published in Evolution, takes a new approach to this hotly debated topic by using global data modeling to build continental "Ëœclimate footprints.' "Between 50,000 and 3,000 years before present (BP) 65% of mammal species weighing over 44kg went extinct, together with a lower proportion of small...

If Earth is headed for a mass extinction like the previous five, in which more than 75 percent of all species were wiped out, then North American mammals are one-fifth to one-half the way there, according to a University of California, Berkeley, and Pennsylvania State University analysis. Many scientists warn that the perfect storm of global warming and environmental degradation - both the result of human activity - is leading to a sixth mass extinction equal to the "Big Five" that have...

Mammals may be nearly half way toward mass extinction If the planet is headed for another mass extinction like the previous five, each of which wiped out more than 75 percent of all species on the planet, then North American mammals are one-fifth to one-half the way there, according to a University of California, Berkeley, and Pennsylvania State University analysis. Many scientists warn that the perfect storm of global warming and environmental degradation "“ both the result of human...

U.S. scientists say the Earth is in the midst of its sixth mass extinction of plants and animals, with nearly 50 percent of all species disappearing. Biologists at the University of California-Santa Barbara say they are working to determine which species must be saved. "The current extinction event is due to human activity, paving the planet, creating pollution, many of the things that we are doing today," said study co-author Assistant Professor Bradley Cardinale. "The Earth might well...

It's a half-dozen Carmen mountain white-tailed deer, scraping at the ground with bootlike hooves, bending gracile necks to chew on wet soil and lick it dry. They're harvesting the minerals and moisture from our urine soaked into the parched earth of the high desert, the herd toiling through the night and into the morning in a pursuit...
