Moths Repeatedly Evolved Genital Sound Weapons Against Bats
Original: Moths Keep Evolving Their Genitals Into Anti-Bat Weapons, Again And Again https://www. sciencealert.com/moths-have-re pe
Scientists report that multiple moth lineages have independently evolved a strange defence: rubbing their genitalia to produce ultrasonic clicks that jam bat echolocation. The repeated evolution of this anti-bat 'scream' across unrelated species highlights how strong predatory pressure from bats drives similar adaptations again and again.
Why now: The finding of repeated independent evolution of such a bizarre defence mechanism is a striking example of convergent evolution, drawing interest from science readers.
