Throughout the natural world, we see special design features that allow animals to survive in environments that place unique demands. Chameleons have an eye-brain connection that enables the eyes to rotate independently of one another or work together when needed. Chameleons use their tongues to catch insects, but to capture their food, both eyes must work together to overcome depth perception issues. At the same time, chameleons are very vulnerable to predators, so their eyes must rotate independently to look in several directions at once. We find another example of unusual eyes in the genus of four-eyed fish, Anableps.
Anableps live in northern South America and Trinidad, where they swim in the surface waters of lakes and rivers. Near the surface, they are easy prey for birds, so they need to see above and below the water simultaneously. They appear to have four eyes, two above the water surface, and two below the surface. In reality, they are not separate eyes. The eyes are divided into two sections, separated by a band of tissue.
Each section of the Anableps eyes has two corneas, two pupils, a single egg-shaped lens, and one retina that is also divided. The portion of the eyes located above the water connects to a different section of the fish’s brain than the area below the waterline. These four-eyed fish are ideally suited to fill an ecological niche that no other fish can.
You might think that all fish could use this design, but every ecological niche has animals designed to inhabit and maintain that location. Anableps are unique, and that makes them popular aquarium fish. More importantly, this unique design speaks of God’s imaginative creativity in providing full use of every resource on planet Earth with creatures like the four-eyed fish, Anableps.
One of the more trusted sources of science and history is the National Geographic Society. Their popular magazine, books, and TV programs have been used to promote particular viewpoints, and sometimes they have been deceived. Many of our older readers will remember a cover story in the magazine about a Chinese fossil that the magazine ran as proof of a particular evolutionary theory. It later turned out to have been constructed by local people as a means of selling claimed fossils. Now there is an issue with fake Dead Sea Scroll fragments.
The Museum of the Bible collection of Dead Sea Scroll fragments, which the National Geographic has used extensively, are fakes. They consist of 16 fragments claimed to be from authentic Dead Sea Scrolls. The forgers used old pieces of leather, and after writing on them, they treated the documents, so they looked ancient. The museum released a report by Colette Loll on March 13, 2020, explaining that microscopic analysis of the fragments showed cracks in the leather filled with pools of the ink. That means the leather had cracked after a long period of time, and the ink ran into the cracks in modern times. Other evidence also showed that these were fake Dead Sea Scroll fragments.
The message for all of us is to realize that any scientific claim based on historical objects needs careful study. Claims of antiquity should be read with a skeptical eye to the evidence. There is a lot of money involved in ancient artifacts, documents, and writings. Since National Geographic has such acceptance and worldwide circulation, they are particularly vulnerable to forgery attempts.
The Bible is very clear in teaching that the best way to conduct oneself sexually is to have one partner for life. As people have veered away from God’s teaching and instruction, sex has lost its meaning, and people with multiple partners do not find the joy and satisfaction in sex that God intended. We are now learning that the consequences of multiple sexual partners are more than just a lack of satisfaction and joy in sex. There is also a strong connection between cancer and sexual promiscuity.
USNews.com carried a study of 5722 men and women with an average age of 64. It showed that women who had ten or more sexual partners were 91% more likely to have cancer than those who had either one or zero partners. Men who had multiple partners had a 64% higher risk of cancer. The sample size is too large to just blow off this data. However, some researchers suggest that those with multiple sex partners also had habits that elevate cancer risks, including drinking alcohol and smoking cigarettes. But the research shows a strong connection between cancer and sexual promiscuity.
We would suggest that God gave us moral laws for our good. The Creator who designed us knows what behaviors will benefit us and which will not. In Matthew 19, some Pharisees asked Jesus why Moses allowed men to have more than one wife. His response was, “Because of the hardness of your hearts, Moses allowed you to put away your wives: but from the beginning, it was not so” (Verse 8). When we violate God’s plan, the consequences are not just emotional and mental, but there are physical health issues as well.
There are a vast number of things in our bodies that we take for granted. Perhaps at the top of that list is our tooth design.
Our teeth have to withstand chewing motions that spread forces around. They must be able to hold, fracture, and fragment food items without being broken themselves and do this millions of times over a lifetime. Their opposing surfaces must align to a fraction of a millimeter. They also exist in an environment that is teeming with life. Our mouth is populated by some 700 different species of bacteria, some of which produce lactic acid, which attacks the enamel.
The bacteria are essential because they fight disease, help with digestion, and regulate various body functions. In ancient times the bacteria were limited because of the diet of ancient humans. Now with massive amounts of sugar in our diet, the bacteria are catalyzed in their reproduction. Our saliva buffers teeth against the lactic acid and bathes them in calcium phosphate, which remineralizes their surface.
Teeth have hard enamel caps made up of calcium phosphate. The material is composed of thousands of rods called crystallites, which are 1000th the width of a human hair. These are grouped together in bundles called prisms with tens of thousands of prisms per square millimeter. These prisms run parallel to each other, weaving and twisting as they go from the surface of the tooth to the underlying dentin. Dentin is made of tiny collagen fibers that run between structures called tubules. This tooth design resists cracks and gives toughness and impressive durability.
So if these things are true, why do I have cavities, problems with wisdom teeth, and expensive trips to the dentist? The answer to that question is diet. When we study ancient humans, we don’t see decays in their teeth, impacted wisdom teeth, or evidence of gum disease. In the animal world, it is rare to see a cavity or a decayed tooth. The struggles we have with our teeth is because we have softer and more sugary foods than our ancestors ate.
I find it interesting how various denominational creationists handle the existence of dinosaurs and how they fit into the Genesis 1 account. We still see some who deny that dinosaurs ever existed even though we have many specimens, including dehydrated ones. Others maintain that dinosaurs were innocent plant-eating friends of Adam and Eve. That is even though paleontologists have found fossils of smaller dinosaurs in the stomachs of more massive dinosaurs. Still, others ignore the literal meaning of the animals listed in Genesis 1, and they include dinosaurs in the “beasts of the earth” category. Some maintain that dinosaurs were the ancestors of birds, and so they are in verse 20. So can we find dinosaurs in Genesis 1?
Recent studies of dinosaur eggs have introduced new data for those who study dinosaurs and the Bible to consider. Detailed studies of Hypacrosaurus eggs have shown that there are growth lines in the shells of the eggs. We don’t see those growth lines in bird eggs, which hatch in a relatively short time. Some of the eggs studied by researchers have growth lines indicating very long incubation periods – in some cases, up to 12 months.
We see growth lines in modern reptiles that bury their eggs and let them incubate for months. Changes in temperature and other environmental factors mean the eggs go through periods of dormancy when the growth lines appear. This lengthy process is especially true of large eggs. Researchers have found some dinosaur eggs the size of footballs, which would require a very long incubation period. All of this would suggest that the large dinosaurs, at least, were not birds. The more data we get on the dinosaurs, the more evidence shows that they were not directly related to any modern animal. They were a group of their own.
Just as God did not tell us about viruses, bacteria, and unique animals like the platypus, He didn’t tell us about dinosaurs in Genesis 1. They were part of the preparation of the Earth for humans. When we read, “In the beginning God created the heaven and the earth,” we are reading an undated historical account that simply says God did it – not how or how long it took. The week of Genesis 1:3-31 hadn’t started yet. When it began, the animals described were those familiar to Moses and his readers.
We tend to view the wings of a butterfly as we do our fingernails or hair. We think of them as lifeless, rigid structures that serve as airfoils only useful for flying. Researchers at Columbia University led by Dr. Nanfang Yu have discovered that butterfly wings are more than inert tissue. The wings are equipped with living tissues that serve other critical factors for the butterflies. The design of butterfly wings is more than beautiful.
Using thermal imaging, the scientists measured the emissivity of the wings. That means the ability of the wings to emit thermal energy. Butterfly wings have veins that carry hemolymph (insect blood). Male butterflies also have scent patches that release pheromones for attracting mates. The researchers found that the emissivity of the veins and patches was very high. That means the wings of butterflies are engineered to emit thermal energy to prevent the insect from overheating in the hot sun.
The veins of the butterfly wings are covered with a thick layer of chitin, which is the material that makes up the insect’s exoskeleton. The patches on the wings have tube-shaped nanostructures and extra chitin. Thick and hollow materials are better at radiating heat than thin, solid materials. Butterflies are designed to handle high temperatures, and science is just beginning to understand how the design of butterfly wings works to cool the insects.
The study included more than 50 different butterfly species. The conclusion the scientists reached is that butterfly wings are “living structures” not inert material. The design of butterfly wings prevents the insect from overheating as well as allowing it to fly.
That butterfly in your garden is not only beautiful but a creature with a highly complex design. We are still learning about the fantastic transformation that takes place when a caterpillar changes into a butterfly. The study of the butterfly’s wings adds another layer of design and intelligence to what God has done with these incredible insects.
Touch your nose and then touch your dog’s nose. Notice any difference? Like most mammals, your nose is at the ambient temperature. Your dog’s nose, however, is cold and wet. We have known for a long time that vampire bats have cool patches in their nasal areas that act as heat detectors to help them find warm-blooded prey. Researchers have now found that dogs have a very similar structure. Perhaps infrared-seeking dog noses have the same purpose.
A dog’s nose is packed with sensitive nerves. Researchers say that dogs can detect a warm surface at a distance of five feet (1.5 m). When a warm object is placed near a dog in a cold, dark room, the dog will respond to the object even though there is no visible light in the room. Brain activity goes wild in the area that is connected to the nose.
A friend of mine had a dog that would dig up moles in his yard. The dog would move around with his nose to the ground. Then he would suddenly stop and begin digging. Every time, he would flip out a mole. I told my friend he could make a fortune if he could train ten dogs to do that. Now, at last, I know how the dog did it.
Want to make a fortune? Invent an infrared detector sensitive enough to detect a mole six inches below the surface of the ground. It would be hard to do, but God designed infrared-seeking dog noses so they could find prey that is not visible to our eyes.
Just a few hours ago (11:49 p.m. EDT March 19 or 0349 GMT March 20, 2020) spring arrived in the Northern Hemisphere. Officially it is spring, even though it may not feel like it where you live.
For the next three months, the days will continue to get longer as the Sun moves farther north. This year, the Sun reaches its greatest northern latitude on June 20 when it will be at its highest elevation in the Northern Hemisphere sky. In the Southern Hemisphere, it will be at its lowest elevation. The autumn equinox will arrive on September 22. Then, on December 21, the Southern Hemisphere will have the Sun directly overhead at 23 degrees south latitude while it will be at the lowest point in the north.
At Chichen Itza on the Yucatan Penninsula of Mexico, the Mayans built a huge pyramid to a serpent deity around A.D. 1000. They engineered the pyramid so that at the spring equinox, the Sun’s light resembles a huge snake slithering down the steps on the structure’s face. The Mayans called the equinox “the return of the Sun Serpent.” They recognized the reliable and consistent seasons that make life possible. They could not comprehend everything required to create that consistent reliability. They didn’t know the God who created all things.
Scientists today use SETI to search for intelligent life elsewhere in the universe. They use telescopes and space probes to look for an exoplanet suitable for life. So far, after millions of hours and unknown amounts of money spent searching for alien life, the results have been zero.
The orbit of the Earth around the Sun produces variations in the seasons with four orbital positions having particular significance. Today, March 19, 2020, the Sun will pass directly overhead at the equator. The exact time will be 11:49 p.m. EDT (0349 GMT March 20, 2020). We can rejoice that the vernal equinox arrives today!
This is the earliest equinox in the United States in 124 years! As you can see in the diagram, the usual date for the vernal equinox is March 20 or 21, depending on where you live on the Earth. The reason it arrives on the 19th this year in North America is somewhat complicated, but it has to do with leap years and daylight saving time. We won’t get into that, but I thought we should explain why the diagram differs from this year’s dates.
There is wonderful history of how the Greek scholar Eratosthenes of Alexandria used the equinox to measure the circumference of the Earth. He knew that on the equinox, a pole stuck vertically in the ground left little or no shadow at noon, depending on location. He compared the length of the shadow of a pole in Syene, a town in southern Egypt, with one in Alexandria in northern Egypt. Using the difference in the shadow lengths, he calculated the circumference of the Earth. His calculation was very close to the known circumference today, and it proved the Earth was round. He did that in 245 BC, long before Columbus sailed.
The four polar positions roughly predict the seasons that have been used by every culture to control planting, harvesting, and preparing the soil. In Genesis 1:14, God said, “Let there be lights in the expanse of space to divide the day from the night, and let them be for signs, and for seasons, and for days, and years.” God not only instituted day and night, but He also positioned the Sun and Moon so they could be used to mark the seasons we would need to live on this planet.
As the vernal equinox arrives today, we wish you a happy equinox!!Enjoy the season and the official end of winter in the Northern Hemisphere. We will have more on the spring equinox tomorrow.
For the past two days, we have been examining the Laws of Thermodynamics. As I said before, In 41 years of teaching high school physics, I learned that the hard part of teaching is getting kids to want to understand physics concepts. The concepts are easy if the students can see some application to their daily lives. But if they don’t understand the relevance of the subject, they won’t try to understand it. To get their attention, I called the unit on thermodynamics “Break the Thermo law and You Don’t Survive!” The three laws of thermodynamics are fundamental truths that apply to all of science, and we would not be alive without them. Today, we look at the Third Law of Thermodynamics.
THIRD LAW OF THERMODYNAMICS: Absolute Zero is a Limit that, Like the Speed of Light, Can Be Approached but Not Reached.
This statement of the Third Law is called the Nernst heat theorem, and, like the other two laws, it just makes sense. If matter were to reach absolute zero, then all atomic motion would stop. If electrons stopped orbiting around the positive nucleus of atoms, what would happen? Opposites attract, and the electrons would be pulled in by the protons in the nucleus. Matter would simply dissolve!
Interestingly, the Bible says that at the end of time, matter will dissolve (2 Peter 3:10). If you stop time and all motion that depends upon time, the Third Law of Thermodynamics tells us that all matter would dissolve. The design of the cosmos shows wisdom and purpose.
The laws of thermodynamics and the multiplicity of other laws that are known to science, all show that the creation is logical and open to understanding. We can see the evidence for the existence of a Creator of the cosmos through the things He has made (Romans 1:19-22). Understanding what God has done and something about how He has done it is what science is all about. Studying God’s creation is a wonderful, useful, and practical way to grow intellectually and spiritually.
