We are finding more new mammal species while we continue to cause mass extinctions.
Since the last summary of the world’s mammals was published in 2005, tallying the roughly 5,400 mammalian species then known, Dr. Helgen said, an astounding 400 or so new species have been added to the list. “Most people don’t realize this,” he said, “but we are smack-dab in the middle of the age of discovery for mammals.”
Yet as he and other biologists are all too aware, we are also smack-dab in the middle of a great species smack down, an age of mass extinctions for which we humans are largely to blame. Estimates of annual species loss vary widely and are merely crude guesstimates anyway, but most researchers agree that, as a result of habitat destruction, climate volatility, pesticide runoff, ocean dumping, jet-setting invasive species and other “anthropogenic” effects on the environment, the extinction rate is many times above nature’s chronic winnowing. “Our best guess is that it’s hugely above baseline, a hundred times above baseline,” said John Robinson, an executive vice president at the Wildlife Conservation Society. “The problem is, we’ve only described an estimated 15 percent of all species on Earth, so most of what’s going extinct are things we didn’t even know existed.”
Scientists recently announced the discovery of a small monkey in the Amazon. It's a small saddleback tamarin monkey.
Completely Dead, Except For Those Living In Zoos
China’s Père David’s Deer (Elaphurus davidianus), is listed as extinct in the wild.
