Marvels of Engineering in Nature

In the creation, we see many patterns that are marvels of engineering. You might not think that shape of a structure is vital to the survival of living things, but it is. As we look more and more carefully at the design of natural things, the evidence shows us that they are not products of blind chance but designed for a purpose.

Considering materials science, the honeycomb design is an excellent place to start. The magnificent honeycomb design uses hexagons stacked into a lattice. Does that make a difference? The answer is a very strong “yes.” The honeycomb must hold a very heavy and dense liquid requiring careful weight distribution. If you designed a honeycomb in a rectangle or triangle pattern, the weight would be on the bottom of the holder, causing it to collapse. In the hexagon design, the weight is distributed in three directions, reducing stress on the bottom.

We see this hexagonal pattern in many areas in the natural world, such as columnar basalt in the structure called Devil’s Tower in Wyoming. As the original molten mass cooled, it contracted, and the structure’s shape relieved the gravity forces.

Using a scanning electron microscope, scientists studied common sea urchins (Paracentrotus lividus). They found that the point where their spines attach, called tubercules, have a mathematical pattern of polygons called a Voronoi pattern. The tubercules must withstand strong forces, and the Voronoi pattern provides strength in a lightweight skeletal structure. This pattern gives maximum strength to organic structures that must withstand significant stresses.

Researchers say this design allows sea urchins to withstand predator attacks and environmental stresses. Besides bees and sea urchins, dragonflies also benefit from Voronoi patterns. The scientists studying these marvels of engineering hope that they will “inspire new developments in materials science, aerospace, architecture, and construction.” We can learn much by studying the designs God has used in creation.

Ants Are Essential for Life on Earth

“Go to the ant, you sluggard; consider her ways and be wise.” That biblical injunction from Proverbs 6:6 was written to motivate the lazy and idle person to get busy. The fact is that ants are among the most important life forms God created, and scientists are finding more evidence that ants are essential for life on Earth.

Over 20 quadrillion ants are living on this planet. That’s 20, followed by 15 zeroes. When you add up the total weight of the carbon in those 20 quadrillion ants, you get about 12 million tons. That is more than the combined mass of wild birds and mammals, or about 20% of the total weight of all humans.

Scientists have studied and named more than 15,700 species and subspecies of ants, and their research is adding more to that number each year. Ant chemistry is vital to the existence of all kinds of life. For example, in my army survival training, they taught us to eat ants.

Many people think of ants as pests that serve no purpose but to irritate us and bring problems into our homes. By contrast, research has shown that ants provide a massive service to humans, and we could not survive on planet Earth without them. For example, consider these roles that ants play:

Ants aerate the soil, disperse the seeds of many plants, and break down organic material, enriching the soil and enhancing plant growth.
Ants create a habitat for other animals and provide an essential part of the food chain for mammals and birds. Also, many birds rely on ants to flush out their prey.
Ants are predators that keep populations of other insects in check. They are more effective than pesticides in helping farmers produce food. Ants eat many worms, caterpillars, and insects that eat our crops and leave no destructive chemicals as pesticides do.

Like much of what God created for our benefit, ants help us in many ways we overlook. Managing God’s gifts requires protecting life forms, including ants. Ants are essential for life on Earth. Remembering the verse from Proverbs, we need to “consider the ant” in more ways than one.

Cannibalism in Animals and Human Cannibalism

Many things separate humans from all other animal life on Earth. One difference involves cannibalism. Scientific research has shown the extent of cannibalism in animals. In the wild, there are countless examples of animals eating their own offspring, the offspring of others, or even a mate. Cannibalism is an easy way to get food, and among predators, nearly all animals who are carnivores sometimes practice cannibalism.

Population density is a significant factor leading to cannibalism in animals. Also, a sick animal unable to get food in the usual way will frequently resort to cannibalism. Some animals will eat other animals’ young to avoid their offspring having to compete for food. Animals such as bears and lions will kill and eat their offspring to stimulate the females into early estrus. Many reproductive issues are involved in animal cannibalism.

Why do some tribal groups practice human cannibalism? The answer is almost never because of food shortages which often lead to cannibalism in animals. However, there is one biblical case where hunger led to cannibalism. Second Kings 6:24-29 tells about a war that caused famine in Samaria, leading two women to agree that they would boil their two sons and eat them. The first woman’s son was cooked and eaten, but the second woman hid her son. The response of the King when he hears of this shows that it was not an accepted practice.

There are cases where people in extreme duress have eaten human flesh. However, human cannibalism practiced in jungle civilizations involves religious reasons, not the desire for humans as food. Instead, they would eat an enemy’s brain to gain their knowledge or their body to gain their strength.

It isn’t just our culture that finds human cannibalism repulsive. Christianity teaches that the human body is the temple of the Holy Spirit (1 Corinthians 3:16). Our Christian heritage has taught us that human life and the temple in which it resides are special and sacred.

Jesus told His followers to love their enemies. The Greek word “love” here is “agape,” which means “to consider of enormous value.” Our enemies are still unique with eternal souls, making them of incredible worth. This is far from the atheist philosophy of “survival of the fittest.” Killing a human is contrary to all that Jesus uniquely taught. As society drifts away from Christ and His teachings, spiritual cannibalism takes over, leading to war, suffering, and perhaps even physical cannibalism.

What It Means To Be Human

In my lifetime, the definition of what it means to be human has gone through many changes. When I was in high school, defining a human was based on the use of tools. Since then, people have observed crows, monkeys, and ants using primitive tools. Physical characteristics like brain size and erect posture fail on several fronts and, therefore, cannot be what distinguishes humans. Some have suggested that group dynamics are characteristic of humans, but bees, ants, and naked mole rats exhibit very complex group dynamics.

Scientists use the term “eusociality” for instances where colony members play various and separate roles to ensure the group’s survival. Now researchers have discovered plants that display eusociality. Dr. Kevin Burns at Victoria University of Wellington led a study of the staghorn fern Platycerium bifurcatum, an epiphytic plant. Epiphytic plants grow on other plants or trees and get their moisture and nutrients from the air. These staghorn ferns grow in colonies on trees in Australia.

Ferns reproduce by spores that originate on the fronds, which are the leaves of the ferns. The research team found that these ferns produce two types of fronds. Strap fronds are long and narrow and produce energy for the colony by photosynthesis. Some also produce spores for reproduction, but 40% do not. Nest fronds varied in size and shape and did not contribute to reproduction. Instead, they anchor the colony to the tree and provide for water and nutrient storage. In this colony of ferns, we see separate roles to ensure colony survival. With each of the roles contributing to the colony’s survival, this is an example of eusociality.

In the system of life on this planet, we see animals and even plants that do surprising things, showing design by an intelligent Creator. With that in mind, defining what it means to be human cannot be merely based on what we can do. The biblical definition of humans avoids that problem by describing humans as created in the image of God. Our spiritual makeup is what makes us unique. Our physical characteristics and what we can do physically cannot define what it means to be human. We are created in the Creator’s image, which sets us apart from the rest of the creation.

Infectious Diseases Can Spread from Animals to Humans

The Centers for Disease Control and Prevention tells us that three-quarters of “new or emerging infectious diseases” in humans originated in animals. Medical scientists call them zoonotic infections. Furthermore, six of every ten known infectious diseases can spread from animals to humans. Diseases that originated in animals include SARS, Zika, Ebola, West Nile, HIV, COVID, and Monkeypox. Some diseases, such as HIV, have jumped to humans because of sexual relationships between humans and animals.

As the human population grows, people have more contact with animals and use more animals for food. In addition, the pet trade has seen a massive increase, with a wider variety of animals being confined to homes and sharing everything from beds to meals with their human owners.

Those who blame God for the diseases that are such a serious problem should understand that God never intended for animals to replace humans as family members. A virus that may be of no consequence or even helpful to an animal can cause severe problems for humans. The Old Testament contains strict hygienic rules designed to minimize disease transmission when raising and using animals for food. The rules also forbid using blood as food and any sexual relationship with animals. (See Leviticus 17:12 and Deuteronomy 27:21.).

We may think the biblical instructions for using and managing animals were just for religious purposes. However, it is evident that God knew infectious diseases can spread from animals to humans, and He wanted to protect His people. This is one more example of the consequences of rejecting the Bible as a source of information on how we should live and what our priorities should be.

Remarkable Molas or Ocean Sunfish

The largest fish in the world weighs over two tons, is 14 feet tall, and has bones instead of cartilage like sharks and rays. It’s the mola or ocean sunfish. The remarkable molas live in temperate and tropical oceans worldwide.

A female mola can produce up to 300 million eggs at a time. When they hatch, these fish weigh less than a gram and are 2.5 mm (.098 inches) long. The hatchlings have a back fin that folds into itself, forming a rudder called a clavus. Molas get their name from the Latin word for “millstone” because of their circular shape. They are not good swimmers using large dorsal and anal fins to move while steering with their clavus. In spite of that, molas sometimes breach, jumping 10 feet into the air to shake off parasites. Small fish help them by eating the parasites. When they are on the ocean surface, molas even allow birds to clean away the parasites. As a result, most mola sightings occur when birds are cleaning them.

Why would God create such odd fish as the remarkable molas? The answer is that molas are significant jellyfish controllers. Jellyfish have very few enemies, and left uncontrolled, they would soon dominate the oceans and become a hazard to humans. Molas are designed to be unaffected by the stinging cells of jellyfish. They have small mouths with teeth fused into a beak-like structure. This boney beak enables them to eat any species of jellyfish without being injured by their stinging cells.

In recent years, we have seen numerous cases where humans eliminate predators, throwing nature out of balance. The result is that nature becomes overrun with species previously controlled by predators. For example, here in Michigan, eliminating wolves and bears has caused the deer population to skyrocket, creating big problems for humans.

People are the worst enemies of the remarkable molas. When we discard plastic bags, they often end up in the ocean, where molas mistake them for jellyfish and swallow them, resulting in suffocation. So once again, we must manage what God has given us more carefully. If we don’t, the result can be catastrophic.

Frozen Frogs that Thaw Out and Live

Among the most incredible designs in the natural world is how God equipped various animals to survive winter. Some of the methods are relatively obvious. Burrowing deep under the frost line is one method. We have noted in the past the complex way bears give birth to young and retain urine while hibernating. Wood frogs are unique because they don’t burrow underground for protection from the cold. Instead, they become frozen frogs during the cold months.

Wood frogs are amphibians, meaning they are cold-blooded because they can’t generate any body heat. In winter, the water freezes in the frog’s cells but doesn’t expand and rupture them. They have a natural antifreeze preventing the cells from bursting when they freeze.

When spring arrives, the water inside the frog melts, and the frog awakens. Males immediately begin making a sound like a quacking duck, attracting females. Next, the male will grasp the female with his forelimbs wrapping around her torso. He squeezes until she releases her eggs into the water, where he fertilizes them. The males have a thumb that swells during the breeding season, enabling them to grasp the females.

Scientists are trying to understand how the wood frog’s cells can freeze without rupturing, causing death. Medical science wants to know how to freeze living tissue without damaging it for organ transplants. Many questions are still unanswered in the freezing and recovery of the wood frog. Why don’t all amphibians have this capability, and why is it limited to these creatures?

God has designed special equipment and chemicals to sustain life in all kinds of environments. So when we look at incredible designs, such as frozen frogs, we can know there is a God who created these unusual life forms. (Romans 1:20).

Animal Environmentalists – Pygmy Marmosets

People have only recently begun to realize that we must manage the environment in a way that doesn’t destroy the resources we need for survival. However, we see many examples of animals using conservation measures to preserve a vital resource. A classic example of animal environmentalists is the pygmy marmoset in the western Amazon of South America.

Pygmy marmosets are the world’s smallest monkeys. The heaviest they get is about four ounces, and their largest size is nine inches. Because of their “cuteness,” people have captured and sold them as pets since they don’t bite, are quiet, and are easy to feed. People feed them sugar syrup along with a few supplements. In the wild, one of their main foods is high-sugar-content tree sap. Pygmy marmosets drill holes into a tree and lap up the flowing sap, and they can keep the hole open as long as needed.

The interesting thing is how pygmy marmosets manage this resource. Drilling holes in multiple trees gives them enough nutrients to sustain a large population. However, making many holes in a tree and keeping them open would eventually kill the tree. So how do these animal environmentalists avoid killing off their food supply?

The PBS program Nature told of researchers who spent a month studying the pygmy marmoset lifestyle in an extremely remote part of the western Amazon away from human interference. The answer is that the monkeys let the holes heal over and switch locations to avoid extracting too much sap from one tree. In this way, they don’t damage the trees and have a constant food source. The question is, how do they know to do this? The human way of doing things might be to pull out everything from one tree and then go to the next until none were left.

God has built a system of checks and balances into the natural world, allowing it to function indefinitely. It is only when humans upset the balance that trouble ensues. Animal environmentalists such as pygmy marmosets display the wisdom of God’s creation.

What Good Is a Mouse?

Most of us have an aversion to the mice that invade our homes and businesses. I saw my wife jump onto a chair when a mouse ran through our kitchen. When I asked her why she was so afraid of a two-inch-long rodent, I promptly got a lecture about the diseases mice carry. That was followed by a challenge to God about why He created such a varmint. What good is a mouse?

The fact is that mice are essential to Earth’s design. Mice provide food for a wide variety of other forms of life and serve as God’s tools for various important environmental uses. For example, beach mice help to maintain our ocean shorelines. In this day of rising sea levels, we need tools to prevent shore erosion that allows flooding and storm damage to cause massive damage and kill people. Humans have removed mangroves and stripped barrier islands of the vegetation that ordinarily would keep the water in check. That results in catastrophic damage from storm surges.

A segment in the PBS Nature television series in September showed how scientists have found that beach mice are correcting this problem. They dig underground tunnels where they can escape from predators. In those chambers, the mice store large quantities of seeds from sea oat plants. Sea oats grow rapidly and send out root structures that lock the sand grains together.

When a mouse is captured by a predator or moves to another location, it leaves the sea oat seeds behind. The seeds sprout and proliferate, thanks to fertilizer that came from the mice. The result is that in a short time, a barrier island or dune will have a jungle of sea oats growing on it to break up waves, dissipate energy, and stop flooding from storm surges.

All animals can indeed bring viruses and germs to humans if we allow them to be close to us. However, animals do many good things for us, and even the mouse is an example. God created everything for a purpose, and beach mice provide good ecological benefits through their lifestyle. So what good is a mouse? Looking closely, we can see the purpose of mice and all other living things that share our planet.

God Created Two Books

How have you arrived at the belief system that governs your life? God created two books we are called to use as the basis for our lives, morals, and religious practice. Since these two books have one author, they must be complimentary and cannot conflict. It is strange that many people read one book and refuse to look at the other. That is true of both atheists and religionists.

One of the books is the Bible, and it calls us to use it as a guide for life. Second Timothy 3:16-17 states it very clearly: “All scripture is given by inspiration of God, and is profitable for teaching, for training, for guiding and for moral discipline so that the man of God may be complete and adequately equipped for all good work.” Atheists reject this book because it involves denying one of a few physical pleasures and gives a purpose in living other than survival. Living selfishly has its rewards, and that is attractive.

God created two books, and the second book is the creation itself. The Bible is full of admonitions to use the things God has created as a means of knowing truth and learning how to live a productive and rewarding life. The Old Testament calls us to use what we see in the world around us as a guide to life. The entire book of Job carries that message. Numerous Psalms call us to see God’s wisdom and design and shape our beliefs in them. (See Psalms 8:3-9; 19:1; 53:1-4; 139:14-16.) Proverbs is full of admonitions to learn from the creation. (See Proverbs 6:6; 8:1-7 and 22-36.)

In the Sermon on the Mount, Jesus used the created world as the basis of much of His teaching. (See Matthew 6:26-30; 7:16-20.) Romans 1:18 – 23 says of humans, “That which can be known of God lies plain before their eyes for God himself has made it clear to them. For those things of God which the eye can not see, ever since the creation of the world, are clearly perceived through the things that are made, and are clear to the eye of reason, even his eternal power and divine character so that men have no excuse.”

So God created two books, and it is clear why atheists do not wish to read and apply the Bible to guide their moral and spiritual lives. It is hard to understand why people who claim to believe in God refuse to look at the creation as a source of instruction and guidance. Some are too lazy to read the Bible and study its message, and others are too lazy to read the creation and learn its message. We need to read and study both books so that we can do what 1 Peter 3:15 tells us: “Revere Christ as Lord in your hearts and always be ready with your defense whenever you are called to account for the hope that is in you, yet argue gently and cautiously with meekness and respect.”
