Scientists say humans are "mutilating the tree of life" and pushing our biosphere to the brink - and much quicker than previously thought.

Human activity has caused species groups to go extinct 35 times faster than they have over the past 500 years

'In the long term, we’re putting a big dent in the evolution of life on the planet,' says Gerardo Ceballos, conservation scientist at the National Autonomous University of Mexico

The passenger pigeon. The Tasmanian tiger. The Baiji, or Yangtze river dolphin. These rank among the best-known recent victims of what many scientists have declared the sixth mass extinction, as human actions are wiping out vertebrate animal species hundreds of times faster than they would otherwise disappear.

Human actions are wiping out vertebrate animal species hundreds of times faster than they would otherwise disappear. Researchers are calling for immediate political, economic and social action on unprecedented scales to prevent further extinctions.

A study shows that 73 complete branches of the evolutionary tree have disappeared in the last five centuries

The phenomenon of species extinction is a natural part of evolution, and a recent study suggests that the loss is not limited to individual species but extends to entire genera of animals.

The passenger pigeon, the Tasmanian tiger, and the Baiji (Yangtze river dolphin) are among the most recognized casualties of what many experts refer to as the sixth mass extinction. This is a consequence of human activities leading to the vanishing of vertebrate animal species at rates hundreds of t

Like the comet striking the dinosaurs – in slower motion, but just as deadly – human activity is hacking off entire branches from the tree of life, a new study confirms.
