THE South American bush katydid (Copiphora gorgonensis) has ear less than a millimetre long, yet they work in a way very similar to human ears. The insect can distinguish a wide range of frequencies from long distances. For example, it can tell the difference between the sound of another katydid and the ultrasound of a bat that is hunting.
Consider: The katydid’s ears are located on its two front legs. Like the human ear, the ear of the katydid collects sound, converts it, and analyses the frequency.
But scientists have discovered a unique organ inside the ear of this insect—a pressurized fluid-filled cavity that looks like an elongated balloon. This organ, which they named the acoustic vesicle, works like the cochle of mammals but is much smaller. The acoustic vesicle is responsible for the katydid’s remarkable hearing.
Professor Daniel Robert, of the University of Bristol’s School of Biological Sciences in the United Kingdom, says this discovery will help engineers “develop bio-inspired hearing devices that are smaller and more accurate than ever before.” Researchers believe it will also contribute to the next generation of ultrasonic engineering technology, including imaging
systems for hospitals.
What do you think? Did the remarkable hearing of the katydid come about by evolution? Or was it designed?
LOL, not the driods we are looking for, move long 😀 The insect has a cool Latin name though I suspect taken form the mythical Gorgon, although looking around some Saturday nights in Glasgow as I was passing through im not sure Gorgons are so mythical!

Thanks for the reference robbie, can you share what issue?

Evolution has been proven beyond all reasonable doubt. There's is not a shred of evidence for the existence of a Godlike creator. Hence, whenever a question such as Robbie's appears, the correct answer is always evolution.

no the answer is always, 'what seems more plausible to us' for example biochemist Dr. Davey Loos explains his faith, in the same magazine.
