Carbon Dioxide-Concentrations-Heart Attacks-Brain Cells

Evolution of earliest horses driven by climate change

Some 56 million years ago, rising temps and concentrations of carbon dioxide caused mammals, including tiny Sifrhippus, to shrink. New research offers new evidence of why and how it happened and provides clues to what might happen to animals in the future from global warming. read more..
