When it comes to the inner ear, there is NO WAY Evolution came up with this. It’s sheer genius!
30 [At the creation of the world and man] I was the craftsman at his side day after day, rejoicing always in his presence, 31 rejoicing in his whole world and delighting in mankind.
We have discussed the outer ear, the middle ear, and now we will discuss the inner ear. If the shape of the ear, the canal and eardrum weren’t enough, along with the three bones that are fully grown at birth and amplify sound 20-fold for the next step in hearing, then the inner ear will finally persuade you that Evolution had nothing to do with the human body.
The foot plate that is at the end of the stirrup moves in and out causing waves in the inner ear’s fluid. “The bony chamber of the inner ear is shaped like a small snail shell, from which it gets its Latin name cochlea. The function of the cochlea is to take the mechanical vibrations from the ossicles [small bones] (and ultimately the eardrum) and convert them into electrical signals understandable to the brain.” From, “A Pocket Guide to the Human Body,” page 36-38
“Inside the cochlea are three canals. The middle canal is a spiral, filled with a special fluid. Running within this spiral canal is yet another fluid-filled channel called the cochlear duct. As the piston movement of the middle ear [foot plate] causes waves to travel through the fluid in the cochlea, the cochlear duct bounces up and down.
Inside the cochlear duct is a strip of tissue known as the organ of Corti…here the ear converts signals at a molecular level.”
This organ essentially consists of three rows of outer hair cells and one row of inner hair cells. The tops of the cells have tiny “hairs”…these hairs are actually cilia that are much smaller than a hair on our bodies.
The tips of some of the hairs are attached to an overlying spiral membrane called the tectorial membrane. When the organ of Corti bounces up and down, the tectorial membrane wiggles the hairs.
The wiggling of the hairs causes small molecular “trapdoors” on the tips of the hairs to open and close, permitting electrically charged particles (ions) to enter the hairs. Incredibly, the molecular trapdoors are controlled by molecular springs that attach to adjustable molecular brackets. [This is small stuff, y’all].
It staggers the mind to think of tiny molecular trapdoors opening and closing at a rate between 20 and 20,000 times per second, admitting charged ions into the tips of the hairs. This movement of ions generates electrical signals that are sent to the brain, where they are processed and interpreted [as specific sounds].”
I read the material and studied the illustrations and I still don’t know how the brain knows what sounds it is receiving. The inner ear, especially working with the middle and outer ear, is miraculous! And to think that God is WAY beyond physical hearing. He hears us when we mentally cry out, and He answers. If we listen beyond the physical with our spirits, we can hear Him talking to us. He is saying, “I have loved you with an everlasting love, therefore, I have drawn you [to myself] with loving devotion” (Jeremiah 31:3). Let’s respond to that love right now.
Abba, I hear you! Thank You for loving me and drawing me to Yourself with loving devotion. I am Your child, Your creation. The fact that You care for me gives me great joy and comfort. I praise You, Abba. Amen.
Tomorrow: The Heart.
