Answer:
Natural selection is the unethical experiment
The situation you are referring to is called an "Natural Experiment."
What is natural experiment ?Researchers don't intervene or purposefully alter the settings being evaluated in a natural experiment. Instead, they observe and examine information from actual, natural events or circumstances.
These circumstances might not be morally or practically appropriate to purposely generate in an experiment, but they offer useful information and insights into society, human nature, or different phenomena in a more practical and ecologically sound setting.
In order to investigate the impact of certain events or treatments without directly influencing variables as in controlled experiments, natural experiments are frequently employed in the social sciences, epidemiology, economics, and other disciplines.
