In the 1960s, acid rain poisoned Ontario's lakes, and the smallest survivors left a genetic record in the mud that took scientists decades to uncover

Tiny aquatic creatures in Ontario lakes faced severe acid rain in the 1960s. These copepods rapidly evolved to survive the harsh conditions. Remarkably, as pollution controls improved lakes, the copepods adapted again, reversing their earlier changes. This study provides a clear real-world example of evolutionary rescue, showing life's resilience.
