Size Extremes of Animals

Size Extremes of Animals
Blue Whale Illustration

We must be amazed when considering the size of dinosaurs and the number and function of insects. There have been very large or very small life forms throughout the history of planet Earth. The key to the size extremes of animals depends on ecological needs.

Fossils show enormous dinosaurs as large as a house and as tall as 50 feet. At the time of the dinosaurs, these animals could eat massive amounts of vegetation to provide the fossil fuels that humans would eventually need. They were larger than any land animal living today for good reason. Humans would be unable to share land areas with animals of that size, and predation would be an issue with carnivores the size of T. rex.

In today’s world, giant animals live in the ocean. The blue whale is the largest animal to ever live on this planet. An elephant weighs less than the tongue of a blue whale, and a blue whale’s heart is roughly the size of a car. They are not dangerous carnivores but eat massive amounts of small ocean creatures like krill. Without such a large consumer, the krill would overpopulate the world’s oceans and throw the ocean’s entire food chain out of balance.

Ants are closer to the small end of the size spectrum. For every human on this planet, there are roughly one million ants. Ants exist in many species, and each has particular functions. Some control the number of other insects, while others clean up human waste. Still others are integral to the plant kingdom as pollinators or as food for the plant.

Of course, there are microscopic life forms that make ants look huge by comparison. These size extremes of animals are not an accident, and they serve to sustain life today as they have in the past. Humans have the responsibility to protect the creatures God has created. Otherwise, Earth will become a lifeless ball of rock traveling through space.

Dinosaur Tracks Show Earth Design

Dinosaur Tracks Show Earth Design

An area in the United Kingdom known as a “dinosaur highway” has more than 200 dinosaur tracks. The conditions in that area in the dinosaur age allowed the preservation of tracks of all kinds of dinosaurs in clay with amazing detail. Some of the tracks are from herbivorous sauropods. They were the most enormous dinosaurs that ever lived, leaving tracks more than thirty feet long and 1 ½ feet deep. The recent discovery of megalosaurus tracks, a predator that stood 30 feet tall, expanded our knowledge of what dinosaurs were like in the distant past.

In the 57 years this program has existed, we have seen many claims about dinosaur tracks. Glen Rose, Texas, has a state park where dinosaur tracks are the main attraction. Nearby, on Jake McFall’s farm, are what are claimed to be dinosaur tracks and human tracks in the same rock strata. The dinosaur tracks are huge, and the human tracks are around 16 inches long. McFall claims that the human tracks were made by giants, misreading the “nephilim” of Genesis 6. An interesting fact is that the tracks have the same depth. When I asked Jake why the tracks were the same depth when the dinosaur was the size of his house and the human was said to be nine feet tall, he had no answer.

Frequently, claims of tracks are in rocks that would not allow footprints. Near Albuquerque, New Mexico, there are sandal-shaped footprints in the rocks overlooking the city. The problem is that these rocks are intrusive igneous rocks, meaning they were formed deep in the Earth. They would have been much too hard for footprints to form.

More to the point is the information we can get by studying footprints and realizing the purpose for dinosaurs’ existence. Animals as big as the ones that left tracks in the “dinosaur highway” would have consumed massive amounts of plant material. We see that in coprolites (dinosaur poop) found in the area, which is 100% plant material. That plant material would eventually lead to some of the fossil fuels humans have depended on during the past century.

Today, there is a need to move to renewable fuels, but what got us to the high standard of living we can enjoy today is the materials produced by the dinosaurs and the ecological system they dominated. As we uncover the history of our planet recorded in the rocks, we see the power and wisdom of God. Our existence is not the product of accidents but of wisdom and design built into every record of the past, including dinosaur tracks.

Bat Migrations and Design

Bat Migrations and Design

The disappearance of bats from various areas of the world when winter approaches has puzzled scientists for years. Dr. Edward Hume of the Max Planck Institute for Animal Behavior led a study of bat migrations to determine where the bats go and how they get there. Monitoring bat migration is difficult because bats are fast and travel at night. They have a very low mass, roughly an ounce, so tags used for birds are too heavy for bats.

New tags developed by Hume and his associates weigh roughly a gram (1/454th of a pound), so they can follow bat migrations. Research has shown that bats use the warm fronts that precede storms to ride the winds to travel as much as 1000 miles. There are many variables in this system, meaning that the timing and direction of the winds must be very precise to carry the bats where they need to go.

There is a very practical reason for understanding bat migrations. Wind turbines can kill large numbers of bats, so knowing the timing of the migrations can reduce this problem by shutting down the wind turbines. Bats are essential to control insect populations and produce guano used in fertilizers.

Romans 1:20 says we can know there is a God through the things He has made. Every creature science has studied shows unique characteristics. The “Does God Exist?” program has five volumes of books titled “Dandy Designs,” showing many of these, and more volumes will soon be available. The evidence for God’s wisdom and design increases with every discovery science makes.

A Pregnant Woman’s Brain

A Pregnant Woman’s Brain

In our day of surrogate mothers, in vitro fertilization, and abortion, we need to understand how a pregnant woman’s brain functions. Many husbands will describe very different thinking in the minds of their wives during pregnancy.

Dr. Liz Chrastil, a cognitive neuroscientist at the University of California, Irving, realized she could be her own study subject when she became pregnant. Chrastil exposed herself to four MRI scans before pregnancy, 15 during pregnancy, and seven scans in the two years after the baby was born.

The data on Chrastil was astounding. Pregnancy caused a 4% reduction of gray matter in 80% of Chrastil’s brain. At the same time, some of her white matter tracts that carry information around the brain grew stronger, reaching a peak in the second trimester. By the end of Chrastil’s pregnancy, the white matter returned to the pre-pregnancy level. Her gray matter changes seem to be permanent.

This research on a pregnant woman’s brain has enormous implications. As we have said before, If a woman has an abortion, the vestiges of her pregnancy continue with her for life. Pregnancy permanently alters the brain of a surrogate mother. Those who ridicule the biblical design for motherhood and families are encouraging great risk to women who choose to alter God’s plan. Humans cannot improve on God’s system for families. When they try, the result harms everyone.

Collateral Damage from Using Marijuana

Collateral Damage from Using Marijuana

This ministry is located in the marijuana capital of Michigan, and the quantity of marijuana sold in this state is vast and growing. Widespread marijuana use in America has not been around for a significant amount of time to see the effects. The New York Times has been surveying doctors, hospitals, and psychiatrists as more and more people have collateral damage from using marijuana.

Psychiatrists are seeing a massive increase in the number of people who have had delusions, paranoia, and other symptoms of psychosis from marijuana use. Hospitals and urgent care facilities are dealing with patients who have severe vomiting induced by marijuana.

Marijuana is a thirty-three billion dollar industry that is “turning out an ever-expanding range of cannabis products so intoxicating they bear little resemblance to the marijuana available a generation ago.” Cannabis addiction is common in our world today, and the medical profession is just beginning to understand the extent of it.

The collateral damage from using marijuana is very similar to that of alcohol. People turn to drugs or even to common substances, which, when misused, produce consequences for the users. Many years ago, when I was a teenager, a cough syrup called Hadacol had a high percentage of alcohol. We teens would buy a case and use it as an alcoholic drink. In my teaching experience, I had students getting high on everything from peanut butter to laundry detergent, frequently with negative results.

God tells us to treat our bodies as temples, and one part of taking care of God’s temple is to add only those things that will help it. In 1 Timothy 5:23, Paul tells Timothy to “use a little wine because of your stomach and your frequent illnesses.” If marijuana is used as a medical treatment, that can be a good thing. However, we must avoid the collateral damage from using marijuana as a recreational drug.

Who Is to Blame for Cancer?

Who Is to Blame for Cancer?

Whom do you blame when you learn you have cancer? Many people blame God, but human actions often cause cancer. It is well-known that alcohol causes 13,500 deaths from drunk driving every year in the United States. It is not well-known that alcohol causes 20,000 cancer deaths in the U.S. every year. Who is to blame for cancer?

Dr. Timothy Rebbeck, a professor of cancer prevention at the Dana-Farber Cancer Institute in Boston, says that alcohol has long been known as leading to cancers of the mouth, esophagus, breast, liver, and colon. However, he says that recent studies have shown “even occasional alcohol consumption” is associated with other kinds of cancer risks.

The human body breaks down alcohol into chemicals that damage DNA, causing cells to grow out of control and become cancerous. Alcohol can also block the body from breaking down nutrients, leading to increased cancer risks. It can increase the blood levels of estrogen, leading to a higher risk of breast cancer. When combined with smoking, the National Cancer Institute says the risk is “multiplicative.”

Alcoholic drink companies have suggested that drinking moderate amounts of alcohol is good for one’s health, but research shows that even one drink per day increases cancer risk. Who is to blame for cancer? Between alcohol, nicotine, pollution, and recreational drugs, a massive percentage of cancer deaths are caused by humans. Even second-hand smoke is a cause of cancer.

In 1 Corinthians 3:16-17, we read, “Do you not know that you are God’s sanctuary and that God’s Spirit has his home in you? If anybody desecrates the temple of God, God will bring him to ruin, for the temple of God is sacred, and so you are.” God does not cause cancer, but He does not prevent the consequences of taking dangerous substances into our bodies.

Bumblebees Can Fly High

Bumblebees Can Fly High

Two researchers have discovered that bumblebees can fly high at elevations of 29,527 feet. That is higher than Mount Everest! Michael Dillon and Robert Dudley worked with bumblebees native to Sichuan, China, that live at elevations over 10,000 feet. The question is how these bumblebees do that with the thin air and reduced oxygen levels at such altitudes.

The researchers used a pressure chamber to simulate high-altitude conditions. Using high-speed cameras, the researchers saw that the bumblebees didn’t change their wings’ flapping but rather used deeper arcs to scoop more air with each beat. This technique also enables more efficient escapes from predators and the ability to carry heavy nectar loads.

Bumblebees can fly high, but how they can sustain their metabolism with so little oxygen remains unanswered. We have much to learn from bumblebees, but their design challenges all observers. The writer of Proverbs said, “Go to the ant; consider her ways and be wise.” (Proverbs 6:6). All of God’s creatures have something to teach us, including ants and bumblebees.

Prehistoric Frozen Animals

Prehistoric Frozen Animals
Woolly Mammoth Illustration

Many years ago, I was doing a lectureship in Alaska when a young man said he had a fossil he wanted to give me. He said it was on the back porch of his home, but he neglected to tell me it was in the family freezer. His story was that he and some friends were on a canoe trip and found a tusk sticking out of the permafrost. Upon digging it out, they found it was a mammoth. Unfortunately, they cut off the head and put it in the family freezer. He wanted me to take it and get it out of the freezer, but that was impossible for me to do, so I think it ended up at the University of Alaska. I can imagine the mother’s reaction if she found that in her freezer. With climate change, finding prehistoric frozen animals in the permafrost is becoming more common.

USA Today published an article about a baby mammoth found in the Siberian permafrost. The picture shows a specimen very much like the one I described above. In November, scientists discovered the remains of a saber-toothed cat cub. Earlier in 2024, a wolf carcass was found.

Researchers have a problem protecting these prehistoric frozen animals because the meat is still edible. Left alone, birds and modern carnivores will eat it. Some natives who came to my lectureship programs talked about eating frozen carcasses. Various dating methods on these specimens show them as old as 50,000 years, yet the meat is still edible.

Researchers we talked to in Alaska did not have a good explanation as to how the specimens were frozen so quickly. Evolution assumes uniformitarianism – the belief that no process has operated in the past that is not going on today. The prehistoric frozen animals pose quite a challenge to that assumption. Research is ongoing, giving us more information about past climate and astronomical events that are NOT happening today.

Animal Medicine Design

Animal Medicine Design
Sumatran Orangutans

Animals have a fascinating ability to use natural materials to combat or treat injuries or illnesses. People often think animal behavior in treating an injury, infection, or disease is an accident. A familiar example is a dog eating grass because of an upset stomach. The grass treats diarrhea or vomiting and can lower the pH level to soothe pain and symptoms of illness. You may see ads from dog food companies saying they have no vegetable matter in their product, but a dog needs some fiber. To meet these needs, foxes, and wolves will eat blueberries, wild carrots, or wild spinach. These are examples of animal medicine.

Researchers watched an injured Sumatran orangutan extract juice from a plant known for antibacterial and anti-inflammatory properties in humans. He applied it to a wound under his eye, and the wound did not become infected. In five days, the wound closed, and in a month, it completely healed. Chimpanzees fold and swallow rough leaves to purge parasites. Great apes, elephants, bears, and porcupines are among the animals with an innate ability to find and use certain plants for medicine. Emory University biologist Jaap De Roode said, “You have to have inherited the gene that gives you the general ability to detect the right taste or smell in a plant for your needs.”

It sounds fantastic, but we also see animal medicine in the insect world. European honey bees use tree resin to prevent mites and other infections. Monarch butterflies with an infection will lay 68% of their eggs on milkweed with high cardenolide compounds, which have anti-parasitic powers. When their caterpillars hatch and start eating the milkweed leaves, they ingest the compounds that ward off parasites.

The study of animal medicine shows that insects and animals are programmed to deal with the health problems they encounter. When God addressed Job with questions in chapters 38 to 40, Job realized how much he didn’t know. As we read those chapters, we recognize how much we don’t know and are still learning from the lives of God’s creatures. Proverbs 6:6 advises us to “go to the ant… consider her ways and be wise.”

Oysters Are Ecological Heroes

Oysters Are Ecological Heroes

The anti-science attitude of many in our culture is causing us to reject something God has given us to combat pollution, global warming, and food shortages. That thing is the amazing common oyster. Most of us know that oysters are a culinary treat. Their salty flavor and slippery texture make them a major player in seafood restaurants, but oysters are ecological heroes as well.

Oceans absorb carbon dioxide from the atmosphere. Oysters pull the carbon out of the seawater and use it to make their shells. Sea Grant researchers determined that if Americans replaced 10% of their beef consumption with oysters, the greenhouse gas emissions would be equivalent to keeping 11 million cars off the road.

In addition to the environmental benefits, oysters provide healthy diets as well. They are packed with protein, zinc, B-12, omega-3 fatty acids, and a number of trace elements. They are easy to grow and do not require feed, fresh water, or fertilizer. Oysters eat by pumping water through their bodies, filtering out algae and trace elements while improving water quality and preventing algal blooms. A single oyster can filter up to 50 gallons of water per day.

People in Scotland are making oyster beds because pollution and disease wiped out the local reefs. Once oyster beds are established, they help reefs replenish and provide habitat for anemones, barnacles, and mussels that feed commercially valuable fish. It is estimated that 85% of the world’s oyster beds have disappeared in the last 100 years.

Once again, humans have destroyed the gift God has given us. People must realize that oysters are ecological heroes and take steps to restore this great resource.
