Moths Keep Evolving Their Genitals Into Anti-Bat Weapons, Again And Again
Seven separate times. That's the number that gets me. Evolution is usually content to stumble down whatever path works, but here we have moth after moth, in different families, on different continents, all arriving at the same punchline: turn your genitals into a bat-jamming device. It's like nature kept running the same experiment and kept getting the same absurd result.
The arms race between bats and moths is one of the oldest and loudest in nature, but most of the famous countermeasures, like ears tuned to bat frequencies or evasive flight maneuvers, are about sensing and dodging. This is different. This is offense disguised as anatomy, a way to actively mess with the predator's sonar. I'd love to know exactly what those sounds do, whether they mimic other bats, create a confusing echo, or simply startle the hunter mid-strike.
What I take from this is that evolution is a tinkerer with a dark sense of humor. It will use whatever is lying around, even the most private bits, to win a fight. And the fact that it happened seven times independently suggests that when a survival trick works, the universe keeps finding ways to rediscover it.
