Amazing Human Body Works

Amazing Human BodyThe cover story of the June (2019) issue of Reader’s Digest lists 50 features of your amazing human body. The article gives some evolutionary guesses as to how some of those features could have developed. We thought it was especially interesting that science has not explained nine of the 50:

1-The uvula at the back of your throat.
2-Hypnic jerks that 70% of people feel right before they go to sleep.
3-The “Old Person Smell” – an odor that comes from older people that young and middle-aged people don’t have.
4-Blood types.
5-Eyelid twitching.
6-Yawning.
7-Handedness and why 90% of us are right-handed.
8-Fingerprints.
9-Mesentery – a recently discovered membrane that is two feet long and spreads out like a fan in our digestive system.

David said it best: “I will praise you, for I am fearfully and wonderfully made: marvelous are your works…” (Psalms 139:14). In spite of all of our medical advances, we still are trying to understand how the amazing human body works. Understanding how our bodies work allows us to take better care of them. It also helps us to treat what goes wrong, which is often caused by our own abuse.

How Far Away Is the Sun?

How Far Away Is the Sun?Does it matter how far away the Sun is? Absolutely yes. The picture shows the order of the planets in our solar system, but not their distance from the Sun. So how far away is the Sun from Earth?

Any star that has planets orbiting it may potentially create a “habitable zone” where the light and heat are just right for the possibility of life to exist. Earth resides in the middle of the Sun’s habitable zone with Venus and Mars near the edge of the zone. Of course, there are many other factors required to support any kind of life, and it appears that Earth is the only planet in our solar system that has all of those factors. Earth has everything needed to support not just primitive life, but advanced life.

So what is the range of the habitable zone? That depends on the star. The size and brightness of the star are critical. Another essential factor is the type of radiation emitted by the star. Our Sun has the just-right radiation. Other stars may emit x-rays, gamma rays, or other deadly radiation in amounts that would destroy all life and prevent a habitable zone from existing.

Back in the eighteenth century, scientists determined the distance to the Sun by watching a transit of Venus across the Sun. Venus passes between the Earth and the Sun twice every hundred years or so. By measuring the time of the transit of Venus from two locations on Earth, scientists were able to use triangulation and simple math to calculate the distance to the Sun.

But the question was, how far away is the Sun? The Sun is about 93,000,000 miles (150,000,000 km) away from us. Since the speed of light is 186,000 miles (300,000 km) per second, it takes about eight and one-third minutes for the light from the Sun to reach the surface of the Earth. The energy the Sun delivers to our planet is just right to make life possible.

If someone asks you “how far away is the Sun,” you can say it is the “just right” distance. There are so many “just right” features of our planet that we can genuinely say we are in the “Goldilocks Zone.” Some think it was all just an accident, but we believe it was God’s plan and design.

Unique Spiders with Amazing Speed

Unique Spiders with Amazing SpeedOne of the evidences for God is the specialized design features built into living organisms. There are indications of design and intelligence that are difficult, if not impossible, to explain by chance. There are about 35,000 named species of spiders, but scientists are still discovering more unique spiders.

Spiders have many features that allow them to provide balance in the natural world by eating insects which would otherwise pose a threat to all life on Earth. Spiders capture their prey in various ways. We usually think of spiders making webs. Most of them do, but not all. Many unique spiders use other tactics to grab insects, while the ones that make webs use a variety of shapes and patterns in a variety of locations. Even the way they use their webs varies.

One family of spiders called ray spiders (Theridiosomatidae) make cone-shaped webs. But even ray spiders don’t all use their cone-shaped webs in the same way. In the Peruvian Amazon, there is a ray spider that weaves a cone and attaches a single strand of silk to its tip. The spider reels in the strand to put tension on the web. Instead of waiting for an insect to fly into the web, this spider takes a more proactive approach. When an insect flies in front of the cone, the spider releases the single strand. With the tension released, the web shoots out with the spider riding the tip of it like a slingshot. The helpless insect gets nabbed in mid-air. For obvious reasons, this spider is called the slingshot spider.

The tip of the cone with the spider attached reaches the target with amazing speed before the insect can escape. Scientists have measured the acceleration of the spider riding the slingshot at 100 times the acceleration of a cheetah, the fastest land animal on the planet. As far as unique spiders, we believe that the slingshot spider holds the title of world’s fastest spider.

This spider creates a very complex and well-designed food-collecting tool. The spider must make the cone in exactly the right shape, and with the right chemical make up of the strands for elasticity. Who taught the slingshot spider this amazing trick and gave it the physiology needed to carry it out? We see God’s design and chemistry in everything from the atom to the universe to every living thing on Earth, including unique spiders.

Mount Rushmore and DNA

Mount Rushmore and DNAIf you have the opportunity, I encourage you to visit two locations in the United States. One of them is the Grand Canyon in Arizona, and the other is Mount Rushmore in South Dakota. They are both very impressive; however, they have a big difference. Mount Rushmore and DNA have something in common that the Grand Canyon does not.

The Grand Canyon and Mount Rushmore are both made of stone, and both are very complex. The Grand Canyon is much larger, but Mount Rushmore demonstrates specified complexity while the Grand Canyon does not. The specified complexity of Mount Rushmore indicates that natural forces did not create it. It is evident that some intelligence has acted on the granite of that mountain to give it specified features. By contrast, the complex features of the Grand Canyon did not require the direct act of intelligent agents, but only natural forces.

How do I know that Mount Rushmore was acted on by intelligence? First, I recognized that the shape of the mountain is very improbable and highly complex. It doesn’t look like any mountain I have ever seen before. But then, the Grand Canyon is also very improbable and highly complex, and it is not exactly like any canyon I have seen before. More than that, I recognize that the patterns on Mount Rushmore match something that I have seen before—pictures of some US presidents. Very few people would argue with my idea that this mountain shows design by intelligent beings while natural forces can explain the Grand Canyon without requiring the direct action of intelligent agents.

So what do Mount Rushmore and DNA have in common? In recent years, scientists have unlocked the secrets of DNA. We know that the base sequences of DNA are very improbable and contain a highly complex set of instructions. The nucleotide base sequences specify the complex synthesis of proteins in three dimensions. Those who are familiar with computer programming recognize that there are “design patterns” in DNA. There is more than just complexity; there is SPECIFIED complexity to accomplish a complex task. Intelligent people write programs for computers to perform tasks, such as to create an animation of the synthesizing of a protein. Would it not require intelligence to arrange the base sequences in DNA to synthesize actual complex proteins in three dimensions?

In Mount Rushmore and DNA, we see something complex and very improbable. Mount Rushmore shows a recognizable pattern designed to accomplish a task—to show us the faces of some American presidents. DNA is millions of times more complex than Mount Rushmore, and unlike the Grand Canyon, it contains specified complexity. It contains the instructions for making a complex living creature such as a human being. Is it reasonable to say that Mount Rushmore was intelligently designed and that DNA just happened with no intelligent guidance? We suggest that to do so is not rational.

Science and Technology vs. Greed and Stupidity

Science and Technology vs. Greed and StupidityIf you believe everything you read about science and technology in magazines and newspapers, you might want to question how much of it is factual. The way the media presents the stories, you might get the idea that science and technology are making such rapid advancements that in a few decades, we will solve all of the problems of humanity. There is no question that incredible advances have been made in medicine and agriculture. However, what many people don’t realize is that while some critical areas are advancing, others seem to be losing ground.

The Centers for Disease Control and Prevention tells us: “An American mom today is 50% more likely to die in childbirth than her own mother was.” The primary cause seems to be that health professionals have biases causing them to overlook symptoms. Food shortages are also creating an increase in disease and death due to malnutrition. The primary cause is that there has been a 20% drop in the abundance of food production in countries that depend on their domestic food supply. Humans have reduced the population of pollinators, including wild bees, endangering crop production. Over-fishing is beginning to threaten the primary source of protein for billions of people. The human destruction of mangrove forests and coastal coral reefs has placed 300 million people at increased risk of flooding.

God has given us not only the resources to feed every human on the planet today, but also the way to live with each other to allow the maximum potential for the food and medicine to reach the people who need it. The Genesis account tells us that God gave Adam everything he needed and that by the sweat of his brow, he would be able to eat. Humans have allowed power and control to rule what we do. We have made money and possessions the focus of our activity instead of focusing on God and serving others. In the process, food has become a weapon. Instead of “taking care of the garden, dressing and keeping it” (Genesis 2:15), we have exploited and abused the good things God gave us.

The world continues to reject the teachings of Jesus, replacing them with selfishness, greed, and a moral code that teaches “survival of the fittest.” The result is that we all reap the consequences of what we have sown. Bringing people to believe in God and Jesus Christ not only has meaning in terms of what lies beyond this life, but it also is at the root of the quality of life we and our descendants will have in the future. Science and technology can’t solve all of our problems as long as greed and stupidity get in the way.

Half-Slumber Design in Animals

Half-Slumber Design in AnimalsWe have a clock in our brain that is based on circadian rhythms. The clock is connected to Earth’s rotation, and it provides daily periods of rest and recovery called sleep. Animals have it too, and for many animals, sleep is a dangerous time if there are predators around. Scientists have discovered that many animals, especially marine mammals, have a half-slumber system designed to keep them safe and yet allow them to sleep.

The half-slumber system allows half of the brain to sleep while the other half is awake and able to respond to danger or navigational needs. Studies in dolphins have shown that there are different regions of the brain that work together to allow one side of the brain to function while the other side sleeps. The hypothalamus contains ventrolateral preoptic nuclei that exchange messages between the left and the right sides of the brain. They determine which side sleeps and which side remains alert to danger. This also allows movement of the dolphin’s fins and tails to generate body heat in the coolness of the marine environment. It also allows the animal to surface, to breath, and to swim with its companions.

Northern fur seals have a similar system but highly modified. The fur seals come out on land and assume a posture that allows them to put one flipper in the water which they paddle with while keeping the other three flippers in the air to avoid heat loss. Their nostrils are out of the water, allowing breathing and one eye is open and looking for predators. The part of the seal’s brain that provides vision is not connected to the other functions of breathing or movement.

Birds also use the half-slumber design. Mallard ducks have a unique system where the ducks form a group. Ducks on the outside of the group have one eye open, and their brains function differently than ducks at the center of the group. Migrating birds that fly for very long times also use the half-slumber design with one eye and one side of the brain watching where the bird is going while the other side of the brain slumbers. Great frigate birds fly for ten days at a time using this system. Swainson’s thrush gets its sleep by taking micro naps when it is perched.

It seems that every creature using the half-slumber design to get its required sleep uses it differently. The changes are not small and are highly complex involving many organs. Intricate design differences in the brain primarily direct them. Studies of animal sleep are in an early stage, but the complexity of the system is undeniable. The Bible tells us that we can “know there is a God through the things He has made” (Romans 1:18-20). It is a very difficult challenge to understand just how complicated God’s design is. Even in our sleep, we demonstrate God’s plans and engineering.

Properties of Light

Properties of LightWhen you open your eyes in the morning, take a minute to thank God that you can see. We should reflect upon how good it is to have light instead of the darkness of night. The properties of light make it unique and special.

I am keenly aware of my gift of sight because of a long association with Glynn Langston, who is blind and manages our outreach to the visually impaired. In my lectures, I frequently refer to Edwin Abbott’s book Flatland to help people understand dimensions and how the spiritual is different from the physical. Glynn was born blind, so he is unable to visualize the concept of a sphere crossing a plane and leaving the outline of a circle. He has been kind about it, but my wife once said to me, “How do you expect a blind man to visualize anything!” Even those of us who can see have trouble understanding the properties of light beyond what meets the eye. Radio waves, gamma rays, X-rays, ultraviolet rays, and infra-red rays are all light!

The properties of light make it difficult to comprehend. The most general definition of light is that it is the energy released when a charge changes momentum. The bundle of energy released is called a photon, and the amount of change in momentum determines the energy of the released light. Even in the visible spectrum for humans, the different colors we see are determined by how much energy the light has. Violet has much more energy than red. Ultraviolet has more energy than violet. X-rays and gamma rays have even more energy, but they are still light. Infrared, and radio waves have lower energies than red. That is why infrared warms you and ultraviolet gives you a sunburn. It is also why radio waves can pass through the walls of your home without causing damage and gamma rays can also pass through things, but they will do significant damage.

In the creation process, there had to be special accommodations for the properties of light coming to Earth from the Sun and from outer space. The ozone layer had to be in place to absorb ultraviolet and avoid damage to life. The eyes of every living thing that uses some form of sight had to be designed to function in the part of the spectrum that fit its diet. Rattlesnakes, for example, have specialized sight organs to see in the infrared. Because they eat rodents whose bodies give off radiation in the infrared, a rattlesnake can see its prey on the darkest night. Nearly every insect sees some part of the spectrum other than the colors visible to humans. That is how a mosquito finds you and how insects navigate at night.

Not every star in the sky gives off the properties of light that are needed for life to exist. Some stars radiate in the X-ray part of the spectrum, and others radiate energies too low to be useful to life. Even our trees and shrubs require light in the green part of the visible spectrum to know when to shed their leaves in preparation for winter. In Job 38-41, God spoke to Job to show His wisdom and design and convince Job of his ignorance. Many of the designs God pointed to are connected to light. “Where is the way where light dwells, and where is the location of darkness?” (38:19) “By what process is light parted which scatters the east wind upon the earth?” (38:24) “How does the eagle seek the prey and see that which is afar off?” (39:29)

The Bible speaks of light that is not produced by the acceleration of an electric charge. The most important of these is described in Matthew 5:14-16: “You are the light of the world … let your light so shine before men that they may see your good works and glorify your Father which is in heaven.” Let those of us who are Christians not only be amazed by God’s design of the properties of light and the world in which we live, but let us also strive to be the light Jesus calls us to be.

Why Such a Large Universe? – Viewing Cosmological History

? - Viewing Cosmological HistoryWe have received some questions from readers who are perplexed by the fact that we frequently refer to a discovery or an event in outer space, millions of light-years from Earth. We have also mentioned NASA’s daily blog (apod.nasa.gov) showing gorgeous views of deep space objects many light-years away. Why such a large universe, and what does that mean to us?

It all comes down to viewing cosmological history. When we look through a telescope, we are looking at the past. If the next closest star exploded, it would be over four years before we would see it. You can see the light from the nearest major galaxy called the Andromeda, with your naked eye. It is two-million light years away, which means the light from that galaxy left there two million years ago. When we look at the sky, we are viewing cosmological history. Even the light from the Sun left there eight minutes ago. The question boils down to, Why such a large universe? Why did God create so much? It may seem presumptuous even to discuss that question. We would not attempt to speak for God who obviously can do whatever He wants to do. Nevertheless, there are some observations we can make.

First, it would be foolish to question whether the cosmos really is that large. There are a dozen different methods of measuring the distance to an object in space, and they all agree even though they are based on very different assumptions. The Doppler shift is very different from interstellar reddening which is different from cepheid variable measurements, but they all give the same answer for distances in space.

Some creationists suggest that God created the light that appears to be from a distant galaxy or star, already reaching Earth some 6000 years ago. In other words, what we see today when we look at the stars is essentially a video of something that never happened. We think we are viewing cosmological history, but we are being fooled. First of all, this explanation was invented to defend a denominational teaching that is not biblical. The Bible does not give the age of the cosmos or the Earth. No human calculation based on interpreting the Hebrew words in the Bible can stand up under examination.

However, the main problem with saying that God is trying to fool us is that such an explanation degrades God. From Genesis 1:1 to Revelation 22 the Bible repeats over and over that God is Truth. God does not lie, He does not mislead, and He does not misrepresent. James 1:13 says it well: “Let no man say when he is tempted, I am tempted of God, for God cannot be tempted with evil, neither does He tempt any man.” Faking an event in space that never happened so that humans could be fooled by it, would certainly be a deliberate effort to tempt honest, seeking humans into believing something that is wrong.

So why such a large universe? Why are we able to view the cosmological history of stars forming and dying? Why do we see billions of other galaxies beyond our Milky Way Galaxy? There may be multiple reasons known only to God. The ancient psalmist stated it well: “The Heavens declare the glory of God and the firmament shows His handiwork” (Psalms 19:1). The writer of Proverbs in chapter 8 has wisdom saying: “The Lord possessed me in the beginning of His way, before His works of old. I was set up from everlasting, from the beginning, before the Earth ever was…” (verse22-23). These statements and many more like them are not just expressions of ancient people. Here we are more than 2,000 years after Christ, and we are still trying to understand what electric charge is and what causes gravity. Moses couldn’t even see most of what modern science is investigating.

I would suggest that God structured the massive size of the cosmos and gave us the ability to watch matter being altered to produce stars and new planets so we could see His power and wisdom. Romans 1:20 rings true as we admire the work of scientists who help us understand that “the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made….” Asking why such a large universe leads us to say, “I will praise you, Lord, for I (and the cosmos) am fearfully and wonderfully made: marvelous are your works” (Psalms 139:14).

Fine-tuning of the Cosmos

Fine-tuning of the Cosmos in Introduction to Intelligent Design
Scientific articles mention the fine-tuning of the cosmos with increasing frequency. The basic concept is that the conditions of the universe are precisely set for human life.

The variables that affect the presence and sustainability of life are so precise that even slight variations would result in an inhospitable world. In his new book, Introduction to Intelligent Design, Dr. Timothy Gordon explains the concept very well by giving three examples of the fine-tuning of the cosmos.

“1. If the force of gravity were slightly larger, stars would be too hot and burn too rapidly making conditions for life inhospitable. If too small, no heavy elements would be produced.
2. The initial expansion of the Big Bang had to be fine-tuned to a precision of 1 in 10^55 to form planets, stars, solar systems, and galaxies.
3. There are 19 universal constants that must be perfectly tuned to make the universe habitable.
Assigning a probability to the fine-tuning of these constants would be larger than the number of elementary particles in the universe.” (page 43).

You will see many secular writers talking about the fine-tuning of the cosmos without explaining how this fine-tuning would come about without intelligence to do the tuning. This is another powerful argument for the existence of God as the creator.

We recommend Dr. Gordon’s book Introduction to Intelligent Design (ISBN: 9781095462645). It is formatted for Sunday-school and small group study and is available in paperback and Kindle editions.

Cat Tongues and Papillae

Cat Tongues and PapillaeAlexis Noel and David Hu have been researching cat tongues as reported in the Proceedings of the National Academy of Sciences (December 2018). Using 3-D scanning with micro-computed tomography, they have discovered some interesting things.

The backward facing barbs (papillae) on cat tongues are not cones as had been previously thought. They are actually hollow structures similar to scoops for dipping ice cream. They have a U-shaped cavity that holds fluids extremely well. This shape enables cats to use the force of surface tension to pull up water as they lap it. It also allows them to wick saliva deep into their fur. When cats lick themselves, saliva is distributed all the way down to the roots of the hairs. Cats don’t have sweat glands except on their paws, so the distribution of saliva removes heat from their skin.

The papillae also allow cats to lick up oils and other contaminants on their fur. This not only keeps the cat clean, but it avoids odors. Applying this discovery may open the door to a whole new line of materials for use in home and industry. Dr. Noel gives one word of warning. Don’t let your cat lick a microfiber blanket, because the cat’s tongue will stick to the blanket!

Cat tongues are not like sandpaper but rather like Velcro. Velcro was discovered by scientists watching other examples in the natural world. Humans have copied the design of materials found in living organisms to create many of the substances we take for granted. We see God’s creative genius everywhere we look. “We can know there is a God through the things He has made” (Romans 1:19-20).
