Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher fitness, while others slow or even derail progress. Two populations facing different kinds of change can end up on completely different evolutionary paths. The findings challenge the idea that one population’s response can represent a whole species.
