Migration of Painted Lady Butterflies

Most of us are familiar with the incredible migrations of monarch butterflies. Until recently, scientists could not track a butterfly species migrating distances exceeding the monarchs. It is the migration of painted lady butterflies.

These butterflies weigh less than a gram, so attaching tracking devices to them is impossible. For that reason, the paths traversed by the migration of painted lady butterflies were unknown until researchers developed a tracking system involving hydrogen and strontium isotopes in their wings.

As with monarch butterflies, painted ladies make their migrations over several generations. Unlike monarchs that specialize in milkweed, painted ladies feed on numerous host plants, allowing them to migrate up to 9,300 miles annually. The migration of painted lady butterflies in Europe and Scandinavia involves traveling to Africa and back. In North America, they travel between Canada and Mexico. In Asia, they fly through the Himalayas. Painted ladies are designed to weather cold conditions with yellow fat reserves and by shivering to generate body heat. They can fly up to 30 miles per hour.

Everywhere we look in the natural world, we see examples of design showing wisdom and intelligence. The food chain would be interrupted, and life on Earth would cease to exist without insects designed to withstand all kinds of environmental factors. The migration of Painted lady butterflies is not an accident of nature, but the product of a mind that designed Earth and all that lives on it so we can be here.

Programmed to Survive – Self-Preservation Subroutine

HAL was Programmed to Survive with a Self-Preservation Subroutine

Every living organism is programmed to survive. That is a very broad statement, but let me tell you what I mean. On this website, we often describe the way God designed creatures with the defense mechanisms necessary to avoid, evade, or defend against predators. However, they are equipped with more than defense mechanisms. In computer terms, a self-preservation subroutine is programmed into their DNA. Even plants that have no brain or desires have this self-preservation quality. I’m sure you have seen this when you try to get rid of weeds in your lawn or garden.

Where does this self-preservation subroutine come from? Living things are programmed to survive by their Creator. In 1969, I was a college student in Cincinnati when the science fiction movie 2001: A Space Odyssey opened in movie theaters. The movie depicted space travel and “picture phone” communications. Space travel today has still not reached the level shown in the film, but today’s mobile phones make the picture phone booth of the movie seem primitive. I still don’t fully understand the movie’s meaning, but HAL, a computer with a self-preservation subroutine, fascinated me.

HAL 9000 was programmed to survive and refused to allow the human astronaut to disable him. That was the scary part of the movie for me. The concept of an evil computer or robot with artificial intelligence and a self-preservation subroutine endangering humans has become the plot of science fiction thrillers. Those human creations could become a modern Frankenstein’s monster. That terrifying scenario is what many fear AI (artificial intelligence) could lead to.

You can take some comfort in the fact that human programmers have been unable to design a computer program with a self-preservation subroutine. Look around you, and you will see a myriad of living things that are programmed to survive. God has programmed survival software into every living organism, demonstrating that He is far more intelligent than any human computer programmer. God’s wisdom and creative genius programmed all life to survive for a purpose.

The Design of Penguins

Penguins have features unlike any other living thing. The design of penguins allows them to dive over 100 feet to secure their food. National Geographic magazine lists these unique features of penguins:

1) Their wing shape is unique, allowing them to create a strong thrust underwater.

2) The wings have inflexible joints optimized for swimming.

3) The strong chest muscles allow them to lift their wings underwater.

4) They have elongated hip bones for swimming.

5) Their necks are S-shaped and can be retracted for swimming.

6) Salt-filtering glands above their eyes allow them to excrete salt they take in from the ocean.

7) Penguin bones are very dense for swimming and to withstand the stress of moving through water.

8) Their feathers are designed to adjust to temperatures and density. In hot weather, the feathers are raised to release heat. In cold weather, they lie flat to provide insulation. Penguins have patches without feathers in hot weather to decrease their weight and provide good buoyancy. They add feathers in cold weather to increase their body weight by 30%, making it easier to dive deep.

Realize that all these features are essential for living in their cold climate. To suggest that the penguins evolved from ordinary birds would require all these changes to happen simultaneously. In evolution, Dollo’s Law of Irreversibility states that once a feature is lost it cannot be retrieved. For a bird to become a penguin, Dollo’s Law would have to be broken multiple times.

The design of penguins demands an intelligent Designer to create these eight features in addition to several others. By studying the design of penguins, we can truly “know there is a God through the things that He has made” (Romans 1:20).

Why Did God Create Snakes?

An interesting question we receive is, “Why did God create snakes?” Bible students refer to the serpent in the Garden of Eden, but that was a one-time event and actually dealt with Satan, not with an animal. Why should we, living thousands of years after Adam and Eve, have to deal with venomous snakes? Why do many people have a fear of snakes and even find them repulsive?

The fact is that snakes offer some real benefits to humans, and their creation was not some kind of vindictive act by God. Scientists derived the first ACE inhibitor, a drug to lower blood pressure, from a South American pit viper. By studying sidewinder snakes, engineers have built robots that can wriggle into tight spaces to search for survivors after a disaster. Some people use snakes for food. Rattlesnake meat is a staple in Texas, and every year in March, Sweetwater, Texas, holds the “World’s Largest Rattlesnake Roundup.”

Like all animals, snakes are part of the balance of the populations of various creatures. Rodents are a major food source for snakes, and snakes also eat many insects and animals that threaten humans. Moving snakes into an area where they are not native has caused problems. That is the case with Burmese pythons that were brought into Florida as part of the pet trade and then released into the wild, where they reproduce without predators to control them. In their native environment, they eat large rodents and reptiles.

When people ask, “Why did God create snakes?” they should be reminded that they are not evil or a threat to humans in their natural environment. They have a purpose for existing and are not a negative commentary on God’s creation.

The Mantis Shrimp’s Design

Naturalistic evolution cannot explain many things in nature. For example, why do various birds display colors that offer no purpose and may make them vulnerable to predators? We see one of the most interesting examples that doesn’t fit blind mechanistic chance in the mantis shrimp’s design feature that can exert a blow 1000 times its body weight.

The mantis shrimp uses a club-like feature to strike its prey with a force so extreme that it creates imploding bubbles that increase the force. The question is how the design of the mantis shrimp’s club-like feature doesn’t harm the shrimp. Dr Horacio Espinosa at Northwestern University in Evanston, Illinois, has published a study explaining the mantis shrimp’s design.

Mantis shrimps have layers of mineral-hardened chitin arranged in bundles, with each layer rotated slightly with respect to the layers above and below. You might compare it to a stack of papers that have been twisted, creating a helix-like corkscrewing shape. This arrangement dissipates the strike’s energy and prevents shear waves from damaging the soft tissue of the shrimp.

Engineers are trying to copy this design to increase the toughness of airplane wings and wind turbine blades. They are sure to find more uses in future high-performance materials. We have previously highlighted the mantis shrimp’s design features, including its club, eyes, and visual system. The shrimp’s protective layer is one more example of a design scientists discovered in the natural world that can aid the design of objects beneficial to humans. God thought of these features first, and they are the product of intelligence – not mechanistic, opportunistic chance.

Soil Moisture and Water Shortages

Living on a river that feeds Lake Michigan, we tend to ignore messages of water shortages. There is some irrigation in our area, but nothing like what we see in other regions of the world. Recent studies of global soil moisture show a very different picture.

Drought events at various global locations have caused the loss of 1.614 gigatons of water between 2000 and 2002. (One gigaton is one billion tons.) In the United States, irrigation has been highly contested as rivers in Nebraska and Colorado cannot supply the water needed to grow wheat and other grain crops. Drawing from the water table has caused it to drop over 10 feet in recent years.

Studies at the University of Texas and Seoul National University show that the problem of water shortages will cause more hunger and human suffering if we don’t do something to stop the soil moisture loss. The solution to water shortages is available.

There was no way to recover water lost to the oceans in the Old Testament days, but now there is. We can use nuclear energy and various processes to desalinate seawater. Removing the salt from seawater provides the salt humans need while producing fresh water for irrigation and replacing soil moisture.

God has provided humans with the water we need. In ancient times, humans lived by bodies of fresh water. With the expanding human population, not everyone could live on the shores of lakes or along rivers, so water had to be moved from places of plenty to places of drought. The Romans did this with aqueducts stretching for miles. In the western United States, we can allow rainfall and mountain ice melt to replace soil moisture while supplementing the need for water in cities by the ocean, like Los Angeles, using desalination.

The teachings of Jesus were ones of peace and concern for others. Water shortages have fueled greed and rivalry in areas of our planet. We need to use the nuclear energy God has given us to desalinate water rather than as a tool of war.

Martian Surface Is Inhospitable for Life

As we have reported on this website, the Martian surface is inhospitable for life. New discoveries show that no life exists there now, and the chemistry of material reached by drilling into Mars’ surface does not show that life has ever existed on that planet.

The media suggest that life on Earth is not exceptional while the scientific data shows that our planet is the only place in the solar system where life can exist. Skeptics would like to find life beyond Earth because they feel it would show that God did not create and design Earth for the existence of humans. Unfortunately, the media often cherry-picks previous data while ignoring more recent findings.

In a USA Today article, Erik Lagatta reported that the Curiosity rover detected some strange spheres in the past. At that time the media claimed that biological processes could have produced these spheres. Further tests showed they were mineral deposits that had nothing to do with life. They were probably formed by groundwater circulating through rock pores.

NASA is interested in the rocks on Mars because they can tell us much about the planet’s geological history. Taking a fresh look at a previously collected sample, NASA scientists found fragments of fatty acids, the largest organic molecules so far discovered on Mars. However, fatty acids do not necessarily indicate life because they can be generated by chemical reactions related to geological processes.

The Martian surface is inhospitable for life, but as we have pointed out before, whether life exists elsewhere in the cosmos is not an issue for the biblical account of life on Earth. If there is life elsewhere, God created it. However, we will probably never know because the distances to other galaxies are so vast that we can never travel there to find out.

First Peter 3:15 tells us to be ready to “give an answer to anyone who asks about the hope that we have.” There is vast evidence for the existence of God, and it is essential to know why we believe what we believe so we can answer our children’s questions.

Unique Design of the Peregrine Falcon

Peregrine falcons have a unique design. This bird can dive at speeds up to 240 miles per hour to catch prey. The speed is totally vertical, which means there is a rapid, violent change in air pressure. Those who enjoy hot air balloons must be careful to compensate for the change in air pressure. Even though their assent is slow, the pressure change from ground level to even 1000 feet is significant. The peregrine falcon goes through a much greater air pressure change at a faster rate. Why don’t their lungs explode? The answer is the unique design of the peregrine falcon.

Peregrine Falcons have a bony structure in their nostrils called a tubercle. It acts as a baffle, deflecting strong shockwaves of air and allowing controlled breathing during their high-speed dives. Studies have shown that this design is unique to the peregrine falcon.

It is important to understand why raptors such as peregrine falcons exist. Some birds, such as pigeons, can reproduce in large numbers, exceeding their food supply. The creation always has a balance between the food supply and the population. When I was a teenager, laws protected the deer in Indiana’s Brown County State Park to the extent that they did not have an adequate food supply. The normal predators of deer had been killed off by humans, allowing the population to grow so large that the deer were destroying the vegetation but were still undernourished. When the authorities finally allowed hunting, the harvested deer were vastly underweight. A full-grown deer could weigh less than 60 pounds.

God designed peregrine falcons to control bird populations to avoid the same suffering caused by overpopulation. There is no evolutionary model that adequately explains the unique design of the peregrine falcon and its bony tubercle. Science strongly supports design in the natural world. “We can know there is a God through the things He has made” (Romans 1:20).

Changing Climate Nonsense

It is amazing to see that some people in the religious community are making climate change an issue. As a public school teacher, I can attest that this destructive attitude is often a result of ignorance. Is climate change happening? The answer is yes! Is this the first time humans have had to deal with changing climate nonsense? The answer is no! It would help if religious people would read their Bibles and not rely on religious con artists for their belief systems.

In Genesis 41:53-57, we read about Joseph and the drought that led to famine in Egypt and its neighboring countries. This was not due to insects or war but to climate change. Second Samuel 21:1 and Jeremiah 14:1-6 recount droughts that significantly impacted the history of Israel. Those of us who are older will recall the Dust Bowl era in the United States, which drove many farmers to California due to the changing climate affecting the central part of the Country.

The public schools need to educate young people on the history of climate change in America’s past because we are entering a period of intense changing climate. It is a scientific fact that the climate is changing worldwide. Areas of the United States that were once deserts are now receiving rain, which alters the animal and plant life in those regions.

The water levels in Lake Michigan have changed dramatically over the course of my lifetime. I used to take my earth science classes on field trips to Lake Michigan. We had been experiencing climate change in those days, which produced unusual amounts of moisture, and the lake was higher than at any time in recent history. Houses built along the lake when the water was low were being threatened by erosion. One place I took my classes to was Michigan City, Indiana, where I knew property owners were battling the higher water levels. As we stopped to look at the beach, a more expensive house than any of my students lived in suddenly slid into the Lake right in front of us.

The causes of climate change are very complex. The extent to which human activity contributes to climate change is a subject of debate, but it is certainly not the only cause. When today’s children face a changing climate, we hope they will be better prepared to adapt to it than their parents were. We all must be prepared in advance for a changing climate.

Science Without God Is Nil

Is science without God possible? John C. Lennox is an Emeritus Professor of Mathematics at the University of Oxford and an Emeritus Fellow in Mathematics and the Philosophy of Science at Green Templeton College. In his book “God and Stephen Hawking,” Lennox says, “The more I understand science, the more I believe in God, because of my wonder at the breadth, sophistication, and integrity of His creation.”

Interestingly, science’s growth in the 16th and 17th centuries happened because men like Galileo, Kepler, and Newton believed the universe was built with an understandable, rational, and intelligent design. They didn’t think of science without God, believing the universe was understandable because it was created with purpose, design, and a discernible order.

An atheist must believe that everything that happened in the past and continues today is pure accident. Famous atheists, such as Stephen Hawking and Francis Crick, expressed this belief. Hawking maintained that humans are “mere collections of fundamental particles of nature.” Francis Crick had what he called an “Astonishing Hypothesis.” That is, “You, your joys and your sorrows, your memories and ambitions, your sense of personal identity and free will, are no more than the behavior of a vast assembly of nerve cells and their associated molecules.”

Hawking and Crick possessed great talents in their chosen fields but seemed to lack any reason to trust their minds. Hawking’s “fundamental particles” and Crick’s “associated molecules” cannot be trusted to have any purpose or truth, so how can they contribute to the overall understanding of the cosmos? Science without God becomes an empty shell. We are talking about believing in a creator God who designed the cosmos and us with purpose.

The Psalmist said it well: “I praise you, God, because I am fearfully and wonderfully made; your works are wonderful, I know that full well… How precious to me are your thoughts, God! How vast is the sum of them.” (Psalms 139:14 and 17).
