Mass extinction as the driving force behind evolution
In the history of life there have been five dramatic events that each caused the extinction of more than 70 % of all then living animal and plant species. Life had to prevail against climatic changes, cosmic disasters, and continental drift.New survival strategies as a response to the changing living conditions were the driving force behind evolution. THE SIXTH WAVE OF MASS EXTINCTION - THE FINAL MASS EXTINCTION? Today, scientists are observing the sixth great wave of mass extinction in the history of the Earth. Three animal or plant species become extinct every hour. For the first time, humans are responsible for the destruction of ecosystems, climate change, and the mass extinction of species. Is Homo sapiens bringing life to a critical point and causing the motor driving evolution to stutter? One thing is certain: it is only a question of time before humans themselves become the victims of their unbelievable over-exploitation of life and resources.
