Human activity has caused species groups to go extinct 35 times faster than they have over the past 500 yearsGroups of animal species are vanishing at a rate 35 times higher than average due to human activity, according to researchers, who say it is further evidence that a sixth mass extinction in Earth's history is under way and accelerating.Scientists analysing the rate at which closely related animal species have gone extinct in the past 500 years have found they would have taken 18,000 years to vanish in the absence of humans, and the rate at which they are being lost is increasing.
