The reason why it is best advised that you leave taking care of a mouse or rat problem to a professional is due to the skills and knowledge needed in doing so, as well as the time scale. Behavioural tests of absolute sensitivity and sound localization in naked mole‐rats show that their ability to detect sound is limited, with a maximum sensitivity of only 35 dB at 4 kHz. Park and colleagues tested the hearing of mole-rats using technology similar to that used for testing human hearing. The blind mole-rat is not an example of poor design; rather it is a marvel of God ’s creation, and perhaps one day soon, God, who has given man wisdom, will allow his intelligently designed image bearers to figure out the blind mole-rat’s medical mechanisms and use these lowly rodents to help reduce or eliminate cancer in humans. Among the several rodents referred to as “mole rats” (see zokor), the blind mole rat is among the most molelike in form, having a furred, cylindrical body, short limbs, and protruding incisor teeth. One idea is that the creatures lost some of their hearing ability because the sense isn’t required underground. Another possibility is there are a lot of echoes underground, so the mole rats evolved to have poor hearing to avoid acoustic overexposure. Be first to know!
