Washington, Feb 10 : A scientist has said the fact that we're discovering new mammal species in an era of human-caused mass extinctions, is not a cause for joy, but only a warning for humanity.
The statement has been made by Paul Ehrlich, the Bing Professor of Population Studies at Stanford University, and co-author of an analysis of the 408 new mammalian species discovered since 1993.
Ehrlich conducted the analysis with Gerardo Ceballos, a professor of biology at the National University of Mexico.
The 408 newly discovered species amount to approximately 10 percent of the known species of mammals.
