Cities Are Forcing Animals To Evolve Faster Than Normal

Scientists found that evolution takes at least a million years, but that’s without human intervention. Are we making animals evolve faster?

“In research that will help address a long-running debate and apparent contradiction between short- and long-term evolutionary change, scientists have discovered that although evolution is a constant and sometimes rapid process, the changes that hit and stick tend to take a long time.”

Environmental change triggers rapid evolution

Environmental change can drive hard-wired evolutionary changes in animal species in a matter of generations. A new study overturns the common assumption that evolution only occurs gradually over hundreds or thousands of years.

Global forecasts of urban expansion to 2030 and direct impacts on biodiversity and carbon pools

“Despite projections that world urban populations will increase to nearly 5 billion by 2030, little is known about future locations, magnitudes, and rates of urban expansion. Here we develop spatially explicit probabilistic forecasts of global urban land-cover change and explore the direct impacts on biodiversity hotspots and tropical carbon biomass.”
