Mammal extinctions are far outpacing evolution

A study at the Aarhus University squarely blames the humanity for annihilating animal and plant species at such a dramatic pace that blunts the nature’s weapon of evolution, leaving many organisms on the trajectory of mass extinction within next five decades.

Over the course of 450 million years, five mass extinctions driven by environmental changes have wiped out Earth's plant and animal species but the sixth mass extinction, an exclusive work of humans already underway, could push mammal biodiversity to such an abyss that it may take 3-5 million years to recover to current levels, notes Science Daily.

Lead researcher Matt Davis calls the findings “depressing,” as he explains the implications of human-driven sixth extinction, writes Earther. As smaller mammals replace the grand megafauna, the complex ecological web could unravel.
