Humans are doing away with animal and plant species so swiftly that nature’s in built defense structure, evolution is lagging. An Aarhus headed research team figured out that if the present preservation efforts are not enhanced; so many mammal species will become extinct in the course of five decades that nature will require 3-5 million years to recuperate.
Five vital turbulences over the past 450 million years have been responsible for extinction of majority of Earth’s plants and animal species because of environmental change. Succeeding each mass extinction evolution has developed anew to diffuse the gap created. Now is the time for sixth mass extinction but this time the extinction has not been engendered by natural disasters but by unnatural works of humans.
A team of researchers from Aarhus University and the University of Gothenburg has figured that the pace of the extinction is really fast for evolution to sustain at that rate. If mammals expand at their normal rate it will still take them 5-7 million years to establish biodiversity to its levels prior to evolution of modern humans and 3-5 million years just to reach present biodiversity levels as per analysis.
The researchers utilized their considerable database of mammals, which involves not only the present say species but also hundreds of species that existed in the past and became extinct as Homo sapiens proliferated across the globe. This indicates that researchers could research the total effect of our species on other mammals.
