Global climate change could explain the explosion in marine biodiversity that took place 460 million years ago, according to researchers from INSU-CNRS Laboratoire PaléoEnvironnements et PaléobioSphère (CNRS)Université Claude Bernard Lyon and Australian National University in Canberra. They have found evidence of a progressive ocean cooling of about 15°C over a period of 40 million years during the Ordovician, a geologic period extending from 490 to 440 million years ago. Until now, this geologic period had been associated with a "super greenhouse effect" on our planet. The results from this study were published in the July 25, 2008 issue of Science. Read More...
