Only a trace of human activity remains in this "post Industrial Evolution" environment. In On the Origin of Species, Charles Darwin envisioned a gradual evolutionary change where plants and animals adapted to conditions over time. Has humanity's interference with the natural world derailed this evolutionary model? Social complexities have caused a dependency on increasing amounts of fossil fuels as humanity has affected its own evolution and that of the whole planet's flora and fauna. The coral reefs and Chilean beetles that Darwin studied less than 200 years ago are now considered at risk as peak oil [extraction] looms on the horizon.
