Those reading my posts often read of the marvel of the hearing experience. And yes … you guessed it – here is another interesting article. Much of my motivation in sharing these articles is due to the continuing deterioration of my own hearing. But much of my motivation is simply the fascination of learning about such a wonderful system that has been designed and engineered into our bodies. So let’s delve into this article which shows the Intelligent Design of our hearing experience.
An excerpt from the article —
The Drum Major
Meet Daple, a protein in the inner ear. Those of us whose ears work properly can thank Daple for doing a good job when we were developing in the womb. Deep inside the cochlea of our inner ear, the robot-like Daple was guiding the construction of hair cell bundles, those important antennas that pick up fluid motions and transduce them into electrical impulses in the auditory nerve. Arranged like organ pipes, each hair cell bundle must line up properly to function. The individual hair cells have an assistant protein that puts them in their correct relative position, and another set of proteins controls the axis they need to line up on, but what brings these two functions together?
Until now, scientists did not know how these independent processes were coordinated. We can imagine the confusion of a marching band at half time without a drum major. Who directs the trumpets to go left and the tubas to go right? Who signals when things need to happen? The drum major has been found, a new paper reports in the Proceedings of the National Academy of Sciences (PNAS), and its name is — you guessed it — Daple. News from the Jackson Laboratory explains, how the band “concert” ends up playing on schedule and in tune:
There’s more in the article, and I invite you to read it.
Thanks to the VA, I have what I think is the top of the line in hearing aides and accessories to help me navigate through life’s noises, sounds and conversations. But I can tell you these gadgets are a far cry from the “original equipment.”
For example, I now have a small microphone that I can place on a table and it picks up sounds very well, and voices quite nicely. This is great for one-on-one conversations and watching TV, and a big improvement. But when there are several or more people talking and multiple conversations, or with the TV on, all those sounds are jammed into that single microphone and transmitted to my hearing aids. It becomes very difficult to pick up individual conversations in such a scenario, and it is work to try to do so, and it sounds like everyone is in a steel drum. So in these circumstances I soon give up trying and tune out or leave the room.
Part of the wonder of natural hearing is the ability of the natural hearing system to separate out all of these competing sounds into a pleasing pallet of sound – even that bird singing in the background outside. And I do remember those days.
I know many of you reading this have been indoctrinated for years with the idea that all this is due to Darwinian evolution – natural selection over eons of time. I might suggest to you that it is well past time to abandon such thinking. A good place to start on such a journey is with your own body and body parts, as in the article. Darwin was wrong, and so are today’s “smartest in the world” such as a Richard Dawkins. Unfortunately, those such as Dawkins have a strangle hold in the academic world and don’t allow alternative views to enter the minds of students, or any teaching contrary to the accepted dogma.
On the other hand, those actually involved in research and development in the world of biology (as opposed to teaching) seem to be working in an environment which ignores Darwinian Evolution and embraces Intelligent Design. Much of medical research shows a design and engineering approach to the mysteries of the body.
