The fear of insects is called entomophobia. It’s a phobia affecting nineteen million Americans, making it one of the top fears people have. The insects people most commonly fear are ants, beetles, grasshoppers, caterpillars, and even moths and butterflies. If I selected the insects I dislike the most, they would probably be mosquitoes – at least the female ones. However, we must realize that insects of all varieties are essential for human life, and even mosquitoes serve a useful purpose.
On this website, we have written about insects many times. Instead of having a fear of insects, we would do well to study and learn from them. The following links to some of the insect articles we have posted can help you see that our six-legged friends are fascinating. Let’s start with those dreaded mosquitoes.
Ants and mosquitoes live on every continent except Antarctica. Entomologists estimate there are 20,000 species of ants, but only 13,800 have so far been studied and classified. However, ants don’t hold the record for the largest number of insect species. That honor belongs to another insect family, which we will look at tomorrow.
Trillions of bacteria live in the intestines of every person. Perhaps more disturbing is the suggestion that there are ten times as many bacterial cells in the human body as there are human cells. Remember that bacterial cells are smaller than human cells, but still, that’s a lot. Nobody has actually counted them all, but scientists are certain that the bacterial cells outnumber our body cells. Even though that may sound shocking, the truth is we couldn’t live without them. The collection of microbes inside you is called the microbiome, and it makes food digestion possible and plays an essential role in our immune system.
Every time we eat food, we take in bacteria. Your gut biome acts as the first line of defense in a fully-functional immune response. People often refer to “good bacteria” and “bad bacteria.” That distinction may be misleading because the helpful or harmful ways of those microbes may depend on the circumstances.
Gut bacteria work in the breakdown of carbohydrates. Research indicates that obese people have less diversity in their gut bacteria than lean people have. On the other hand, when gut bacteria digest foods such as eggs and beef, they produce a compound that can boost heart-disease risk. Some germs can make you sick, while others keep you healthy. Sometimes the same bacterial cells in the human body can do either, depending on circumstances.
Helicobacter pylori bacteria are known for causing ulcers in the digestive tract. They are present in the microbiome of half the world’s population. Most people don’t have a problem with stomach ulcers, but it is painful and dangerous for the small number who do. However, researchers have found that the absence of Helicobacter bacteria in the gut may lead to diseases of the esophagus, such as reflux and cancers. Other research has shown that Helicobacter species may help the immune system, even though they may lead to inflammation and ulcers.
So the “good” and “bad” distinction between bacteria may be a false dichotomy. Whether they are beneficial or harmful depends. Bacteria considered “bad” might be neutral or even helpful in certain situations. A person’s health status, stress, diet, and genetics all influence how we react to various bacterial cells in the human body.
Another beneficial use of bacteria could come from research into using them as a medical delivery system to regulate autoimmune diseases. There is a clear answer for those who consider bacteria as all bad and question why God would create them. As science continues to explore the complexity of the system of life, we see God’s wisdom in all of creation.
Discover magazine carried a story titled “Fowls in Love” about two Canada geese nicknamed Arnold and Amelia. Many animals pair up to raise young or for protection. However, evolutionary survival of the fittest fails to explain animals sticking together when one of the pair becomes injured and unable to assist in survival. So do animals fall in love?
The Birdsey Cape Wildlife Center staff in Barnstable, Massachusetts, noticed the male goose limping. He had an open fracture that wouldn’t heal on its own. They caught Arnold and prepared to do surgery to repair his foot. The female goose observed the procedure through the clinic’s sliding glass door. When Arnold awoke from surgery, Amelia was allowed into the room, and she used her beak to preen his feathers. For the next 14 days, Amelia was at the center daily, sharing Arnold’s meals and spending time with him.
After Arnold was released, the staff observed the pair together for two weeks until they left with a passing flock of Canada geese. Do animals fall in love? The article writer concludes that the two geese were in love. The article ends with this statement by the veterinarian who did the surgery, “There has to be some internal motivating force that allows that animal to behave in a particular way, and we call it love – that internal driving force.”
This is a classic example of anthropomorphism, attaching human characteristics to an animal. The biblical concept of love is spelled out uniquely in the New Testament by the Greek word “agape,” meaning to consider the object of one’s attention to be of incredible worth. Jesus used agape in His teachings, and we find it in New Testament references to marriage. Human marriage is not just for survival.
We have numerous geese where we live on the St. Joseph river in Michigan. They are always in pairs, and getting near to one of them or their chicks invites an attack from the mate. Raccoons learn to avoid pairs but will go after an isolated goose or chick. Do animals fall in love, or is there a survival reason?
God has placed an instinctive drive in geese to maximize their chances of survival and success in raising young. The bond between Arnold and Amelia demonstrates how strong the instinctive drive is. It is not the biblical concept of love. When Jesus tells his followers to love their enemies and not resist evil (Matthew 5:38-45), He tells them to do something animals cannot do.
What does it take to enable an octopus to use all eight arms efficiently? Each arm may be in contact with a different substance, and they are soft and pliable, so they can bend and twist in response to whatever stimuli they receive. As a result, each octopus arm moves as if it has its own brain.
Researchers recently discovered that the arms gather data and move independently or with other arms without consulting the octopus’s brain. The octopus has a central brain connected to a nerve ring that connects to each arm. In addition to the arms’ connections to the brain, a nerve connects each arm to another, located two arms away. This arrangement allows each arm to communicate directly with others and with the central brain. The arm’s connections to other arms allow rapid communication to function quickly and efficiently.
Researchers are still studying how the octopus puts all this together to move eight arms in a well-coordinated way. Roger Hanlon, a researcher with the Marine Biological Laboratory, said, “We are in that intriguing ‘mild state of confusion’ that is simultaneously perplexing and exhilarating when unexpected discoveries are revealed.”
God’s design of every form of life is amazing and offers much for science to study and learn. Our understanding of how nerves function and how the brain interprets the signals it receives from the nerves is still in a primitive stage. However, we know that each octopus arm moves as if it has its own brain, making the octopus a very complex and intelligent animal. We see God’s wisdom and creative ability displayed in every form of life.
As a teenager, it was frustrating that I was supposed to spend a third of my time asleep. I thought of sleep as a great time waster when there were so many things I wanted to do. I thought I could accomplish much more by staying awake.
The truth is that humans need sleep, and so do all animals. Birds, fish, and even insects need periods of dormancy to survive. Even plants need “sleep.” Sunlight empowers photosynthesis in plants to produce the nutrients they need for survival and growth. Therefore, it seems that plants should grow faster if they had sunlight 24 hours a day. Not so. If you set up an indoor garden with artificial lights, you will find that the plants need dark periods. You can even change the “seasons” for the plants by varying the percentage of darkness and light.
Instead of seeing sleep as a great time waster, we know that it is a vital biological process essential for the survival and well-being of living things. Sleep is necessary to maintain good health by restoring and repairing the body’s tissues and organs. During sleep, the body produces hormones that help repair damaged tissues and build new ones. Sleep plays a critical role in the immune system, as it helps the body produce cytokines, a type of protein required to fight infection and inflammation.
Sleep is also crucial for the regulation of metabolic processes. Working with our circadian rhythm, sleep helps to regulate appetite and energy balance. Sleep deprivation can lead to increased hunger and decreased production of hormones that regulate appetite, such as leptin and ghrelin. This can lead to weight gain and obesity, increasing the risk of developing several chronic health conditions.
Sleep is essential for more than just physical well-being. During sleep, our brain processes and consolidates memories and data acquired during awake times. The lack of sleep can impair attention, memory, decision-making, and emotions. Sleep aids in the consolidation of learning and the formation of new memories. During sleep, the brain replays and consolidates memories from the previous day, helping to strengthen and make them more resistant to forgetting.
Now that I am old, I appreciate sleep much more than I did as a teenager. I no longer see sleep as a great time waster but as a blessing from God. I have found that some of my best ideas come to me at night. I can wake up with a new idea or a fresh way of looking at things. Sleep has cleared away the fog in my mind so I can see things I had overlooked.
I am also thankful that God doesn’t sleep. We can sleep because He is our protector 24/7/365. Psalms 121:3b-4 says, “He who keeps you will not slumber. Behold, He who keeps Israel shall neither slumber nor sleep.” So when our melatonin level increases and our circadian clock tells us it’s time to sleep, we can rest knowing that God is still at work keeping the world going. “The Lord’s love never ends; his mercies never stop. They are new every morning” (Lamentations 3:22-23 NCV).
Yesterday we talked about ecosystems, what they are, and why they are essential. If you looked at yesterday’s picture, you saw that carbon sequestration was among the “services” provided by ecosystems. Today, there is much concern about atmospheric carbon (carbon dioxide and methane) increasing the “greenhouse effect” and causing global warming. That makes capturing carbon an essential service of ecosystems to protect our survival. One vital area involves African elephants and ecosystems.
Elephants are known as megaherbivores because of their size and the fact that they eat plants. New research has shown that elephants have a “profound” effect on forest ecosystems. We have mentioned before that beavers shape their environment to create ecosystems that support many other life forms. Researchers from Sweden, France, and the United States confirm that elephants are also “ecosystem engineers” that “significantly influence the structure and functioning of ecosystems” such as tropical rainforests in Africa.
The positive connection between elephants and ecosystems involves two aspects of elephant behavior. First, African forest elephants prefer to eat the leaves of trees with low wood density. This is because those leaves contain more protein and less fiber than the ones with high wood density. Secondly, elephants prefer to eat fruit from trees with higher wood density. By eating those fruits, the elephants disperse the seeds of the trees that sequester the most carbon.
Elephants spread more seeds of more plant species than any other animal. The elephant’s diet enables the survival and spread of the trees that store more carbon, keeping it out of the atmosphere. At the same time, elephants reduce overcrowding by the lower-density plants, allowing the larger trees to grow. This balance of elephants and ecosystems helps to protect the planet from excess carbon in the atmosphere.
The study concludes that elephant conservation will significantly affect global climate by controlling the amount of atmospheric carbon. God has designed a worldwide system of many ecosystems that make Earth suitable for advanced life to thrive. Our job is to protect the blessings God has given us to enjoy. Who doesn’t enjoy watching elephants?
An ecosystem is a complex network of living and non-living things interacting with one another in a specific environment. It includes all the living organisms, such as plants, animals, and microorganisms, as well as the non-living components, such as air, water, soil, and climate. These living components are adapted to the non-living components in an interdependent system, with each relying on the others. We see ecosystem design everywhere we look on planet Earth.
Ecosystems exist in water environments, from ponds to streams to rivers to the oceans. They exist on land in forests, mountains, and deserts. They vary from tropical rainforests to frozen tundra. Each ecosystem has a unique balance of species, with each species playing a specific role. This balance is maintained through various mechanisms, including competition, predation, and mutualism.
Ecosystem design provides many vital services affecting human life, such as water filtration, air purification, and food. At the same time, humans have a profound impact on ecosystem management through deforestation, destruction, and pollution. Careless actions of humans can disrupt the delicate balance of ecosystems, leading to a decline in biodiversity, the extinction of essential species, and climate change.
Conservation and management efforts aim to protect and restore ecosystems and maintain their resilience. This involves protecting habitats, reducing pollution, and managing human activities to minimize ecosystem harm. It also requires monitoring and understanding environmental change and taking steps to reduce or correct human-caused impacts. As we protect ecosystems, they provide services critical to life on this planet. That is part of ecosystem design.
An ecosystem is an ecological system. As we think about the multitude of ecosystems, large and small, localized and widespread, we must realize that they are systems. Do systems happen by accident, or do they require intelligent planning? Can complex things come together to form an efficiently-functioning ecosystem on their own? Every living thing consists of many complex systems within the cells, organs, and whole bodies. Ecosystem design involves systems within systems within systems working together in balance.
Can efficient, balanced systems happen without a system designer? If there is a Designer of Earth’s ecosystems, as I believe there is, we owe it to Him to take care of what He has given for our existence and enjoyment. Genesis tells us that God gave humans the job of managing the creatures and ecosystems of planet Earth. (See Genesis 1:28.) We must avoid the rebuke the rich man gave to his unworthy steward in a parable Jesus told. “What is this I hear about you? Give an account of your stewardship, because you can no longer be my steward” (Luke 16:2).
Everyone knows that sunflower heads turn to follow the Sun throughout the day, allowing them to get the maximum amount of sunlight. However, researchers have found another feature that helps sunflowers to thrive. Plant biologists at the University of California, Davis, have published a report showing the incredible design of sunflowers for optimum pollination.
The sunflower head has hundreds of tiny florets. The newest florets are at the center of the bloom, and the most mature are at the edges. Their design forms a distinctive spiral pattern from the center to the edge. Each floret blooms over two days. On the first day, the male part of the bloom opens, presenting pollen. The female stigma unfolds to receive the pollen on the second day. In some way, the florets coordinate their opening, beginning at the edge and moving toward the center. This progressive opening leaves a ring of female flowers outside the earlier stage of pollen-bearing males.
Pollinating insects (primarily bees) tend to land on the edges and walk toward the center. In that way, they pick up pollen after they have walked over the female florets. Then they carry the pollen to a different flower head for cross-pollination. This coordinated opening design attracts as many insects as possible and makes pollination as efficient as possible.
The sunflower’s circadian rhythm, influenced by sunlight, controls the opening of the sunflower’s florets. People, animals, and plants have a built-in circadian clock as part of our design. We see it in the design of sunflowers for optimum pollination.
Understanding how to develop plant cultivars that can optimize pollination is essential since the bee population has been declining. We have much to learn about God’s design in the plant and insect world. Studies like this can help us meet the food shortages affecting many people on this planet.
When I go on a summer road trip, I always return with hundreds of insects smashed on the front of my car. Those bug remains are a real challenge to remove. So why don’t those little critters have enough brains to get out of the way? Bugs and cars colliding is a great summertime nuisance.
Okay, I know those insects that lost their lives playing a game of chicken with my vehicle don’t have very big brains – if they have any at all. I also realize that my car is much bigger than they are and probably traveling at a faster speed, so it’s hard for them to get out of the way. I also realize that the consequences of our brief encounter are much more tragic for them than it is for me. But I have never seen two bugs crashing into each other in mid-air. They can swarm in great numbers and never crash and fall from the sky. They must have some kind of collision avoidance system.
God gave insects the ability to avoid collisions with each other long before cars entered the scene. That fact led scientists at Penn State University to do some research on bugs and cars colliding. They probably can’t do much to give bugs the ability to avoid cars, but they wanted to give cars the ability to avoid hitting each other. Since bugs somehow avoid mid-air collisions with such skill, can their technology be applied to cars?
Even though only a fourth of driving occurs in the dark, half of all traffic fatalities happen at night. (It’s also when many insect species are most active, but that’s beside the point.) Present vehicle technologies for avoiding collisions use Light Detection and Ranging (LiDAR) or image sensors running sophisticated software. The systems are expensive and use lots of energy. The researchers wrote, “…task-specific obstacle avoidance algorithms allow insects to reap substantial benefits in terms of size and energy.” They wanted to learn how the bugs do it with tiny brains and micro-energy.
We have often talked about how scientistsstudying God’s creatures and creation have discovered ways to accomplish tasks more effectively and efficiently. For example, this new research shows ways to avoid vehicle collisions in a simpler, less expensive, and more energy-efficient way using a new algorithm based on the neural circuits of bugs.
God told Job, “If you want to learn, then go and ask the wild animals and the birds, the flowers and the fish. Any of them can tell you what the Lord has done” (Job 12:7-9 CEV). This research may not solve the problem of bugs and cars colliding, but it can help to solve the much more dangerous problem of cars colliding with other cars. Of course, you will still have to keep the scrub brush and bucket of cleanser handy.
People often think of venom or poison as the same thing, but they are not. Even though people may use those terms interchangeably, there are differences in their origin, delivery system, and effects on the body. So, when is it correct to say that something is venomous or poisonous?
Venom is a toxin produced by animals, usually in specialized glands. It’s delivered to the victim through a bite or a sting. Animals use venom to capture prey and for defense from predators – and sometimes humans. For example, snakes, spiders, scorpions, and some species of fish, frogs, and insects produce venom. Venomous animals have specialized structures, such as fangs or stingers to deliver the venom into the victim’s body. The effects vary from mild pain and swelling to severe muscle paralysis and even death.
In contrast to venom, poison is a toxic chemical produced by plants, animals, fungi, microorganisms, or humans in a chemical lab. Poison is usually ingested, inhaled, or absorbed through the skin. For example, many plants produce poisons to protect themselves from herbivores and other potential threats. Poisonous mushrooms, toxic berries, and certain types of flowers are examples of plants that produce poisons.
The effects of poison can depend on the type and amount consumed. Some common effects include nausea, vomiting, dizziness, and even death. Many everyday household items are poisonous and must be secured so children or animals can’t ingest them. Medicines that promote healing or fight disease are often poisonous if taken in the wrong quantities or in the wrong way.
So, if someone talks about a poisonous snake or scorpion, they are using the wrong term. Those animals are venomous. Poison does its damage when ingested, inhaled, or touched. For example, a poison dart frog is poisonous, but wasps, spiders, and snakes can be venomous. Some animals or insects are poisonous if eaten but venomous if they bite or sting. Monarch butterflies are mildly poisonous to potential predators, but box jellyfish are highly venomous and deadly to humans. If in doubt, the word “toxic” covers both, but it’s not as precise.
When saying that an animal is venomous or poisonous, remember this. A poisonous animal, such as a poison dart frog, is always poisonous and does not choose to be. A venomous animal, such as a snake, must choose to administer the venom. Humans can choose to avoid poison, but often they do not. People can take poison by mouth or inject it into themselves or someone else. We call that foolishness or murder. Alcohol is a poison that people consume as a drink, sometimes resulting in death. Self-inflicted poisoning by illegal drugs such as fentanyl is causing many deaths in the United States.
Some people ask, “Why would a good God create venomous or poisonous animals?” There is a good reason because those toxins serve as a defense mechanism or a method to capture prey for food. The more troubling question is, “Why would intelligent humans choose to put poisons into their bodies?” When asking that question, remember that it all started with Adam and Eve. “And the Lord God commanded the man, saying, ‘Of every tree of the garden you may freely eat; but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die’” (Genesis 2:16-17). The good news is that God provided the cure for the poison of sin. “For the wages of sin is death, but the gift of God is eternal life through Jesus Christ our Lord” (Romans 6:23).
