Religious Ceremony Forces Fish to Evolve or Die
Deep in a sulfur cave in southern Mexico, a group of indigenous people have for centuries asked their gods for bountiful rain by stunning the cave's fish with a natural plant toxin. Once the fish have succumbed, the Zoque people scoop them into baskets for eating. Now scientists are finding the ancient religious practice is impacting the fish's evolution.

Those fish that are resistant to the anesthesia survive to pass on their genes, while the others simply meet their demise.
The irony is just pure priceless. Made my day.
