A new paper about the inner ear shows an additional level of organization and architecture that increases sensitivity and frequency discrimination.
The Mind-Body Problem Has Not Been Solved by Naturalism

Several news stories bring back the issue of mind-body dualism with a vengeance.
The Creator Thought of Everything
February 10, 2018
Sometimes little things make a big difference to a plant or animal. Evolutionists can always make up just-so stories, but creationists see God's wisdom even in small things.
Remarkable Cell Processes That Keep You Alive
July 27, 2013
Within the factories of molecular machines that run living cells, including those in the human body, processes occur non-stop that are designed to meet every contingency. Here are just a few examples.
Stem Cell Wars Continue
July 14, 2013
The race continues between scientists desperately seeking a rationale for harvesting human embryos and those who say, having adult stem cells and iPS cells available, they are unnecessary – and their use is unethical.
Why Your Inner Ear Has a Spiral Shape
June 21, 2012
The cochlea in the inner ear, where sound is transmitted to the brain, has a spiral shape resembling a snail shell. It's not just to save space, researchers have found.
Inner Ear Hair Cells Overcome Friction
June 19, 2011
The cochlea, that spiral-shaped structure in the inner ear, is filled with fluid. In this fluid, tiny hair cells called stereocilia are positioned in bundles along the length of the structure. These bundles sense vibrations transmitted into the fluid from the bony levers of the inner ear. The vibrations picked up by the hair cell bundles, each tuned to its own frequency, mechanically transduce the sound impulses by opening ion channels that set up electrical impulses in the auditory nerve, that travel to the brain. But motion in fluid creates friction known as viscous drag. How do the hair cell bundles overcome it? Scientists have figured out that the hair cells in the bundles are not only finely tuned to reduce viscous drag, but actually to employ it for even higher sensitivity to sound.
