The Amazing Bird Migrations

The Amazing Bird Migrations

Spring and fall are busy times for bird migration. As I write this in May 2026, there are more birds migrating over the United States than there are people in this country. The amazing bird migrations provide evidence of design in nature, not of survival of the fittest by chance. That is especially true because those migrations often benefit other species more than the migrating birds, and especially migrations that go beyond where the birds could find warmer weather.

Birds migrate to find food, to find a place to reproduce, to avoid unpleasant weather, and even to benefit other species of life. In the Northern Hemisphere, birds travel north in the spring because there is an abundance of insects and plants that provide food. The weather is also suitable for raising chicks. When the weather becomes colder in the fall, they fly south to avoid freezing temperatures. As birds migrate, they benefit life in the various zones they pass through. Thankfully, many birds don’t migrate and remain in one area all year.

Factors that influence the number of birds traveling on any particular day include weather and light pollution. One factor that has dramatically affected the amazing bird migrations is sky glow. Lights from vehicles, homes, and businesses cause light pollution that has become a major problem for birds, especially in metropolitan areas. Excessive upward-directed light in the evening hours can cause birds to go off course and even run into buildings or other structures. We can help the birds by restricting stren oetlights to face the ground and keeping lighting to a minimum, especially during migration seasons.

how many birds are in the sky over the United States today and to learn more about the Audubon Society’s “Lights Out” program. It is essential for us to be good stewards of God’s gifts and to protect the birds from danger. Birds are essential to all other forms of life on Earth, including humans.

Creating a Smell Map

Creating a Smell Map

It is easy to overlook the importance of the sense of smell. Smell affects human health and safety. The sense of smell plays an essential role in the taste of food. It can also warn us of spoiled or unsafe food by its rancid odor. Smell can give pleasure, as with the fragrance of flowers, or make us nauseated, as when we smell a foul odor. Fragrances can bring back pleasant memories. The loss of smell can cause depression. With those things in mind, researchers are creating a smell map.

Maps of the receptors for vision, hearing, and touch have been developed previously, but this research was the first to create a detailed map of the receptors for smell. The research began by studying the smell receptors in mice. The challenge in creating a smell map is that it is more complex than the other senses. There are only three main receptor types needed for color vision, but mice have 20 million olfactory neurons and more than 1,000 types of odor receptors that detect unique subsets of odor molecules.

Before creating a smell map, the prevailing theory was that the smell receptors were randomly placed. The study showed that smell receptors form horizontal stripes from the top of the nose to the bottom, and the order matches the brain’s olfactory bulb. Further study will explore human olfactory receptors to compare them with those in mice.

This research is important because it will help scientists develop therapies for people who have lost their sense of smell, as has sometimes been the case with COVID-19. As we learn more about how the sense of smell works, we see evidence of design. The bottom line is that we are “fearfully and wonderfully made” (Psalms 139:14). The design of life, and especially the human body, shows evidence of a Designer, not random chance.

Humans Are Viruses on the Earth – or Not

Humans Are Viruses on the Earth – Influenza Virus
Influenza virus 3D illustration

Perhaps you have seen posts or comments online claiming that humans are viruses on the Earth. The argument is that human numbers are growing, and we “feed parasitically on the body of the Earth.” They say we are swarming over the Earth and leaving no part of the planet “untouched by our pollution and destruction.”

The mantra is that humans move into an area, multiply until they consume all the natural resources, then move on to another area, like a virus. Critics suggest that all other mammals live in equilibrium with their surroundings, whereas humans behave like viruses that spread and consume resources. So the question they ask is whether humans are a disease, a cancer, or a virus on the Earth, what are we going to do about it? How can we stop this human virus?

As Christians, we believe that humans were made in God’s image and that God entrusted the first humans and us with taking care of the planet and ruling over it (see Genesis 1:28). Perhaps we’ve done a better job of ruling over the planet than of taking care of it. Some have pointed out that even though the Bible says we were created in God’s image, we are also the ones who introduced sin into the world.

Hosea 4:1-3 is a Bible passage sometimes quoted by those who insist that humans are viruses on the Earth. In this passage, Hosea tells the children of Israel that because they have been swearing, lying, killing, stealing, and committing adultery, God will punish them by allowing them to waste away along with the animals, birds, and fish. You could say that applies to us today, but that might be stretching the context.

It is true that God gave humans the job of being stewards of the Earth, to rule over and protect or conserve the creatures that live here. It is also true that we have often failed in that job, but God always gives us another chance to do better. As for humans introducing sin into the world, God also gave us a second chance on that. The most amazing thing we read in the Bible is that God became a human being to live a perfect life, to show us what that is like, and to bear the punishment for our failures.

As we consider whether humans are viruses on the Earth, we must consider our relationship with the Creator. Perhaps if we can accept what God has done through Jesus Christ to restore us to a right relationship with Him, we will find that we can have a right relationship with the Earth God gave us to live on. Remember that God is the giver of every good and perfect gift (James 1:17).

Secrets of the Bees in National Geographic

Secrets of the Bees

On April 28, 2026, Roland Earnst published an article about bees living in an upstate New York cemetery. The May 2026 issue of National Geographic carried an article titled “Secrets of the Bees,” which complements Roland’s article in several ways.

The complexity of hives is the first point. Bees design their hives to suit the climate where they live. Many have nests below ground, with some bees excavating as deep as three feet. A typical nest will have a vertical burrow with tunnels leading to areas waterproofed with glandular secretions, floral oils, or plant materials. The larvae develop in areas called brood cells, which are stocked with food. In dry areas, a bee called “Ulke’s Pebble Bee” will gather pebbles and bind them together with a mixture of saliva and mud, or resin if these materials are not available.

A second point in the National Geographic article that complements Roland’s article is that bees can learn. Bumblebees can learn to associate certain colors with rewards. Researchers have found that bees can look at a new landscape and navigate around the changes. In other words, bees are not robots that can be stopped by changing the landscape.

A third area of interest is that bees can figure out the most efficient way to reach a flower in a field, allowing them to maximize nectar gain. In describing “Secrets of the Bees,” the National Geographic writers use words like “hidden genius,” “brightest thinkers,” and “remarkable ways” to explain what bees can do. These are words that describe properties God would have given the bees, not accidents of chance. We still have a lot to learn from the smallest of God’s creatures.

Cleanliness on the International Space Station

Cleanliness on the International Space Station
International Space Station

Keeping your house clean can be challenging. Consider what it would be like to have several people confined to a small space on the International Space Station (ISS). You might think that keeping that environment perfectly clean and sterile would ensure the astronauts’ health. That is not necessarily the case. Excessive cleanliness on the International Space Station may cause health problems.

According to a new study, the ISS may be more sterile than it should be. Microbes can be beneficial to our health, and research indicates that low microbial diversity on the ISS may be contributing to immune dysfunction, skin rashes, and other inflammatory issues. The new study suggests that introducing more Earth microbes may help prevent astronaut health problems.

For the study, astronauts were asked to swab 803 surfaces on the ISS and return the samples to Earth for analysis. The returned samples contained chemicals from cleaning products and disinfectants, as well as microbes. Researchers examined how the bacteria and chemicals interacted. Particularly important were the dining, food-prep, and toilet areas.

Microbes in our natural Earth environments may help strengthen our health and resistance to infections and skin problems. We have millions of microbes on our skin and in our gut that are not harmful and actually help us digest our food and fight diseases. While on Earth, we have beneficial microbes all around us, but excessive cleanliness on the International Space Station may not be entirely positive. The researchers suggested introducing microbes from Earth to give a more natural balance without posing any health risks to the astronauts.

Sanitized living spaces may not be as healthy as we think. There are far more microbes on planet Earth than there are people, and we can be thankful that God has placed them here for the benefit of life.

A Natural Tendency to Believe in God

A Natural Tendency to Believe in God

An international research project found that humans have a natural tendency to believe in God. Directed by academics at the University of Oxford, the project involved 57 researchers examining diverse cultures across 20 countries. The project was not intended to prove or disprove the existence of God but to determine whether the concept of God, or gods, is learned or a basic aspect of human nature.

The studies were conducted in both traditionally religious countries and atheist societies. Among the findings were that children as young as age three believed in “all-seeing, all-knowing supernatural agents.” It seems normal for a child to have a natural tendency to believe in God, but atheism must be taught. The research also indicated that adults instinctively believe that some part of their mind, soul, or spirit lives on after death. In other words, people find it natural to believe in the separation of the mind and the body. Project director Dr. Justin Barrett of Oxford University said, “Interestingly, we found that religion is less likely to thrive in populations living in cities in developed nations…”

Project co-director Robert Trigg said, “We have gathered a body of evidence that suggests that religion is a common fact of human nature across different societies. This suggests that attempts to suppress religion are likely to be short-lived as human thought seems to be rooted to religious concepts…” Why would people want to “suppress religion,” or a natural tendency to believe in God? That question is especially significant since the research also found, not surprisingly, that people with religious ties are more likely to cooperate in societies.

This research project was conducted over three years, and the results were published in 2011. Despite the years that have passed, I suspect the results would still be the same today. The bottom line is that people everywhere naturally believe in God and in an afterlife. They have to be convinced otherwise. Are most members of the human race confused and wrong, or is there an inherent truth behind that belief? “He (God) has made everything beautiful in its time. He has also set eternity in the human heart; yet no one can fathom what God has done from beginning to end” (Ecclesiastes 3:11 NIV).

Underground Bees in a Cemetery

Underground Bees
Miner bee Andrena nycthemera

A cemetery in Ithaca, New York, not only has a large number of graves but also an even greater number of bees. Researchers estimate there are perhaps 5.6 million underground bees in that plot of land. It is the largest known aggregation of ground-nesting solitary bees, known as miner bees or mining bees, in the family Andrenidae.

The Andrenidae family of bees consists of more than 1300 species. They don’t build hives, and they don’t swarm. They are solitary bees that live out their lives, build their nests, and raise their young underground. The species of bees that have found a home in the Ithaca cemetery is Andrena regularis. This particular species pollinates crops such as apples and blueberries.

Bees in the Andrenidae family of underground bees are designed to carry pollen on their legs. Various species within this family tend to pollinate specific plant species. We often think of honeybees as essential pollinators, but we tend not to think about or even know about the bees that don’t make honey but are still important pollinators

These underground bees emerge for a short period in the spring and do their pollination work. As temperatures get warmer, they go back underground. Because of the pollen-carrying features of these solitary bees, they can deposit more pollen than individual honey bees. This cemetery discovery is unusual because of how many of them are concentrated in one area. Researchers estimate that there are more than 800 bees per square meter.

God’s amazing web of life is often overlooked because many creatures are largely out of sight and therefore out of mind. These underground bees remind us that there is a lot of life underground, even in a cemetery.

The Smartest Nonhuman Animals

The Smartest Nonhuman Animals
New Caledonian Crow (Corvus moneduloides)

What are the smartest nonhuman animals? You might immediately think of chimpanzees. Why not? Chimps are widely thought to be closest to humans on the evolutionary ladder. However, as we’ve noted before, the similarity between chimps and humans has been highly exaggerated, and it’s becoming clearer that there are more genetic differences between us and chimps.

It may seem surprising, but repeated studies have shown that the smartest nonhuman animals are New Caledonian crows and ravens, meaning they are closest to humans in intellectual ability. Nobody puts crows and ravens in an evolutionary line with human beings, but they have demonstrated their ability to outperform monkeys by retrieving food from a tube accessible from only one end. They can also work out a plan to use one tool to obtain a second tool, which they can use to retrieve food. That’s something monkeys and apes have difficulty doing. There is a YouTube video showing a crow going through eight individual steps to obtain the food it wants.

The ability of New Caledonian crows and ravens to manufacture and use tools and to solve problems with tools greatly exceeds that of chimpanzees, orangutans, and gorillas. What do these birds have that the apes don’t have? The birds have larger forebrains, cerebrums, perineuronal glial clusters, and hippocampi relative to their body size, as humans do. Unlike humans and the great apes, crows and ravens lack a cerebral cortex.

In trying to establish an evolutionary line leading to human beings, we must consider why these birds have brain features humans have, even though the creatures supposedly closest to humans on the evolutionary ladder don’t have them. Perhaps the story is not a common ancestry but a common Designer. When we try to determine the smartest nonhuman animals, maybe we need to consider whether humans are smart enough to realize that evolution doesn’t tell the whole story.

The Strongest Evidence for an Intelligent Creator

The Strongest Evidence for an Intelligent Creator - Human Body

What is the strongest evidence for an intelligent Creator? That is an interesting question. Sarah Salviander, an astrophysicist, suggests that biology offers more convincing evidence than her field of astrophysics. She said, “The incredible machinery of a living cell is far more complex than the structure of an entire Galaxy of stars.” On the other hand, the late atheist critic Christopher Hitchens once said that atheists find the “fine-tuning” of the universe to be “one of the most intriguing” arguments for intelligent design. I think that biology and cosmology together make a strong case for God’s existence.

We have discussed the evidence for a Creator based on the fine-tuning of the universe. Many scientists believe the fine-tuning argument is very strong, as it seems to be the primary basis for postulating multiple universes. We must acknowledge that the evidence shows this universe has been fine-tuned from the very beginning to make it possible for life, including human life, to exist and prosper. Is that fine-tuning the strongest evidence for an intelligent Creator? Since scientists have not been able to explain it, unbelievers advance the unproven and unprovable idea that there are countless universes, and we just happen to live in the one that’s fine-tuned for life.

However, when we look at the evidence for design in living things, especially in the human body, we are in awe. As Dr. Salviander said, the incredible machinery of a living cell is far more complex than an entire Galaxy of stars. Another advantage that biology has over cosmology as the strongest evidence for an intelligent Creator is that we can see it in real time. To see the evidence for design in the fine-tuning of the universe, we must look back in time, but evidence for design in life is all around us right now. The information in DNA shows that life could not have happened by chance, since information comes only from an intelligent source.

In addition, we see beauty in living things and in the physical creation. Chance would create chaos rather than beauty. The psalmist David, who did not know about the fine-tuning of the universe, was in awe of the majesty and beauty in the night sky. (See Psalms 8 and 19:1-6.) The psalmist was also in awe of his own physical body, realizing that God had created him in his mother’s womb. He was awestruck by that, despite having no idea about DNA or the amazing structures within the cells of our bodies. (See Psalms 139:14-16.) Interestingly, Charles Darwin thought that cells were nothing but globs of protoplasm, and he had no idea of the remarkable machines working within every cell or of the DNA that gives instructions for the assembly of proteins to do those jobs.

The bottom line is that, regardless of what you think is the strongest evidence for an intelligent Creator, there is massive and growing evidence that we can’t ignore.

P.S. A new movie, “The Story of Everything,” is coming to select theaters around the country on April 30, 2026. In it, many experts examine two possible stories. Does the universe and life lack purpose and design, or do they show the purpose and intelligence of a divine Creator? I encourage our readers to see this film if it comes to your local theater. Does the fine-tuned cosmos or design and purpose in life provide the strongest evidence for an intelligent Creator? I encourage you to examine the evidence and decide for yourself.

The Wood Wide Web

The Wood Wide Web supports Monotropa uniflora
Monotropa uniflora, or ghost pipes in Glacier National Park, Montana

Hidden underground is a network that enables most green plants to survive. Without it, most green plants would be unable to survive. It’s a network of mycorrhizal fungi. In 1960, a Swedish botanist demonstrated that substances pass between plants through a fungal pathway. In the 1980s, it became clear that most plants form mycorrhizal associations. In a play on words from the “worldwide web,” English researcher David Reed called this underground network “the wood wide web.”

Through this network, plants exchange nitrogen, phosphorus, water, and carbon. These fungal networks collaborate by connecting with one another, forming a vast, complex mycorrhizal network. Although it is not worldwide, it can be wood wide.

An extreme example of a plant that depends on the wood wide web is Monotropa uniflora, also known as ghost pipes. They resemble white smoking pipes, with their stems stuck in the ground. They are white because they lack chlorophyll and therefore cannot use photosynthesis to produce the nutrients plants need. Since the fungal networks form physical connections between plants, allowing them to share nutrients, Monotropa plants freeload on other plants.

Although Monotropa is an extreme example of dependence on the wood wide web, most other plants depend on receiving and sharing the nutrients required for plant life. We normally think of plants as separate units, and we may even think of them as competing with one another, but that is not always the case. Sometimes tall plants, such as trees, compete with smaller plants by blocking sunlight. However, they may also share nutrients underground through the mycorrhizal network.

Only in recent years have scientists discovered the wood wide web, even though it has surely been around since God created plants. This fungal network is still not fully understood, but science is seeking to understand it. How many other things in God’s creation will we discover in the future? It is clear that we have much to learn about the vast web of life. “For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse” (Romans 1:20).
