Ears to You, Katydid!

The human ear is a marvel of engineering and efficiency. Our sensory cells are in liquid, but the ear transfers the energy of sound waves that travel through the air, though that liquid, into something that we can understand. It turns out that the katydid has tiny ears on its legs. After very detailed and careful examination, it was discovered that their ears work like ours. What do evolutionists do? They give credit to the magical sky fairy of "convergent evolution", where there is no evidence and only blind faith to bolster such a belief. They would be obliged to be honest and admit that the evidence shows the work of the Creator.

Katydid ears are only 600 microns (1/40 inch) long, smaller than a rice grain. And they are on the legs, not the head. The new discovery is a tiny and easily overlooked tube, filled with oil under pressure—it bursts when opened. So the researchers used microscopic CAT scans to analyze it. The katydid has an eardrum connected by a lever to a plate inside the tube, and the air side of the lever is longer than the liquid side. So any sound vibrations in the air generate smaller movements but with greater force in the liquid in the tube, where sensor cells detect them. This is a very efficient system, simpler and more robust than ours, and on a much smaller scale.
