I see God in Irreducible Complexity. Today, we begin a journey through the human body and its intelligent design.
7 The fear [and reverence] of the LORD is the beginning of knowledge, but fools despise wisdom and instruction.*
*fool-a person who is gullible, without moral direction and inclined to evil. NIV
One of the things I like about science is that the more we know, the more the Bible makes sense. For instance, when Darwin made his case concerning Evolution, the idea in 1843 was that the human cell was a dark blob of matter. Since then, we know that cells are complex critters that require 23 main parts to interact at one time in order for the cell to live and work and grow. Inside those main parts are many other parts, such as DNA, which is made up of billions of bits of information, and RNA, the part of DNA that builds cells. The question is, which came first: The cell or RNA/DNA? We can’t have one without the other. Hence, Irreducible Complexity.
One Saturday last year, I got a set of pocket guides from Answers in Genesis at a conference. One of them was, A Pocket Guide to the Human Body. It is amazing! We will be spending the next several posts walking through some of the information in this guide. Today, we BEGIN a look at the brain.
The brain has some autonomic (automatic) functions that run the body, but it is adaptable in each of the areas of its control. It is how we learn. Here is a quote from the book on how the brain is laid out.
The neurons that control our senses and motor skills are arranged into an orderly map in the brain, called a homunculus (see pic).
For example, the neurons responsible for touch are laid out in a three-dimensional sequence in the brain, known as a spatial trajectory. If two parts of the body, such as the thumb and index finger, are located next to each other physically, they also have corresponding neurons that are next to each other in the brain. So when scientists attempt to map the sensory neurons in the brain, they find neurons that respond to stimulation of the thumb next to neurons that respond to stimulation of the index finger and so on. The same holds true for neurons that control muscle movement.
Although the neurons in the brain mirror the arrangement of the body parts, they do not mirror the relative size of the body parts. For example, while our arms and legs are much larger than our thumb and lips, they occupy much less space in our brain. The fingers need more space because they require so many more neurons to control fine motor skills and delicate sensations.
So, the more we practice, say, the piano or baseball, the more adapted to the movements used we become. Pretty neat, huh?
Computers are based upon how a brain works–although I’m not sure that computers were designed to work like brains–and they both have a limited amount of space. Information = neurons = space. We have a limited capacity based upon the number of neurons in our brains. Tomorrow, we will look at how the brain decides what to keep and what to remove–all without us being aware it’s going on!
I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well. Psalm 139:14
If we can trust God to build our bodies to function,
we can trust Him with our daily decisions, too.
Abba, may You teach us to trust You in all things. Discovering the amazing construction of our bodies teaches us how to trust You with our daily lives. May we love You all the more for being such a Master Designer and Creator–our Creator. Amen.
