Sometimes a change in the environment becomes a change in evolution.
Field Notes
The remarkable thing about the peppered moth is not that it adapted. Life has always adapted. The remarkable thing is that humans changed the world so dramatically that evolution visibly shifted in response. During the Industrial Revolution, soot from factories darkened entire forests. Tree trunks that had once been pale became black. The atmosphere changed. The landscape changed. And the creatures living within it changed too. We often think of evolution as something ancient, unfolding too slowly to notice. But sometimes a civilization transforms its environment so completely that the effects become visible within a lifetime. The moth is a reminder that we do not merely live inside ecosystems. We reshape them—and they reshape life in return.
