These Animals Can Adapt to Rapid Environmental Changes

The Killifish has become a powerful example of rapid evolution in response to environmental stress. Certain populations have developed a tolerance to heavily polluted waters that would be lethal to most other species. This adaptation has occurred over relatively short periods, making it especially notable. It reflects strong genetic variation and the ability to respond quickly to extreme conditions. Killifish can survive in environments contaminated with industrial chemicals. Their resilience has made them a key subject in scientific research. By studying them, researchers gain insight into how organisms adapt at the molecular level.
