A Rock’s Not Alive

The following came to us from our friend Dr. Phillip Eichman, who has a Ph.D. in biology.

For many years I began the courses that I taught in Fundamentals of Biology and General Biology by bringing two things to class: a rock and something living, usually a plant from the greenhouse. Most of the students had never seen me before and must have wondered why I brought those things to class. One day I surprised the students even more with a turtle that I rescued from the middle of the road. The point that I wanted to make is that there is a vast difference between a nonliving thing and a living thing. The expression “a rock’s not alive” comes from an old Sesame Street song and makes the same point.

A rock’s not alive. It is made up of the same chemical elements as the plant or the turtle, but that is where the similarity ends. Anyone who has taken a biology course will realize that even the simplest living thing has a complex organization. It is capable of taking in and using energy, growing and reproducing, and responding to the environment.

Obviously, something happened to make living things so different from nonliving matter. Either it is a big coincidence, or some higher intelligence planned and directed the formation of life on Earth. More than forty years of studying and teaching biology have convinced me that the latter of these is true. The world in which we live is not an accident, but rather the handiwork of a creator that we call God (Psalm 19:1).

Human-Macaque Chimera Created

Human-Macaque Chimera and Ancient Greek Mythology

A chimera is a living organism made up of parts from different organisms. You have heard myths about a half-woman, half-fish mermaid, and a human torso and head on a horse’s body and legs. Those would be chimeras if they actually existed. Now scientists have created a human-macaque chimera.

Scientists at the Salk Institute in California injected human stem cells into macaque embryos. They allowed the embryos to grow for only 20 days before destroying them. The stated purpose for creating a human-macaque chimera is to find a way to grow human organs for transplant and to develop new drugs.

This reminds us of a science fiction story of chimeras turning into monsters that threaten human beings. The term “chimera” (kye-MER-uh) comes from an animal in Greek mythology with a lion’s head and body, a goat’s head protruding from its back, and a tail with the head of a snake. Imagine what a human-macaque chimera might be like.

This experiment raises bioethical questions. Just because researchers can do this, should they do it, and what kind of research should they carry on? Insoo Hyun, a bioethicist involved in this research, says that chimeras have “the potential to radically humanize the biology of laboratory animals.”

The morals and beliefs of the scientists doing the research become a significant issue in situations like this. We need people with Christian values involved in making these decisions to ensure that everything is done to relieve human pain and suffering, not to create half-human creatures. God has provided the blueprint in DNA, but it is up to humans to decide how to use it. Whether it is for good or evil is an old biblical question.

Story of Earth’s History and Life

In the Yucatan Peninsula and the Gulf of Mexico, the Chicxulub Crater tells a story of Earth’s history and life. The fundamental assumption of neo-Darwinism is that the only processes operating on Earth in the past are processes going on today. This principle, called uniformitarianism, doesn’t work if there have been radical changes on Earth in the past. A catastrophe that wiped out all life would mean that life would have to start over again. Evolutionists have devised elaborated theories to dance around this issue, such as Stephen Jay Gould’s punctuated equilibrium.

A study released in the journal Science Advances on February 24, 2021, involves an exhaustive study of the Chicxulub Crater. This crater is 125 miles (201 km) wide and dates back to the time of the dinosaurs. Many scientists suggested that an asteroid collision produced the crater. Evolutionists resisted that explanation because of the catastrophic effect it would have, and certainly, it is not happening today.

In 2016, researchers took drill cores at Chicxulub to a depth of 2600 feet (792 m). Analysis of the cores has now produced an iron-clad case that an asteroid collision created the Chicxulub Crater. Iridium is an element found in most asteroids, and scientists found massive amounts of it in the center of the crater, with decreasing amounts as one moves away from the center.

In addition to the drill core at Chicxulub, scientists have found iridium in geologic layers worldwide. That indicates tiny fragments of the asteroid were blown into the atmosphere in large quantities blocking the Sun’s light for several years, or even decades. Independent studies have shown that Earth’s surface temperatures dropped by as much as 50 degrees Fahrenheit (10 C), meaning that any dinosaur could not have survived.

This research tells a story of Earth’s history and life that we suggest shows how God was preparing the planet for human life to exist. Suggesting that humans and dinosaurs could have lived together indicates ignorance of the nature of life in the age of the dinosaurs. Not only was Earth’s surface temperature high, allowing massive deposits of coal and other resources for later humans, but the dinosaurs were not a form of life that humans could survive alongside. Evidence shows that T. rex hunted in packs. (See The Week, May 7, 2021, page 24.) The notion that a T. rex could have been a family pet that children could ride, as some religious groups have proposed, is ludicrous.

This story of Earth’s history and life fits with Genesis 1:1, with God using natural processes to prepare planet Earth for humans. Not only is Chicxulub a problem for neo-Darwinism, but it provides more evidence for the integrity of the biblical record when it is taken literally and not twisted to support denominational teachings.

Periodic Cicada or Magicicada

In recent years, people have paid a great deal of attention to insects and how they benefit humans. Some insects pollinate our fruit trees. Others provide food for birds and a variety of mammals–even humans. Insects also help convert waste into valuable nutrients. One of the dangers to the total insect population is over predation because so many animals eat them. One insect species solves the problem in a unique way. It is the periodic cicada or Magicicada that appears every 17 years. These insects suddenly emerge from the ground in massive numbers, as many as 1.5 million per acre, to overwhelm their predators.

Dr. Cliff Sadof of Purdue University has headed up research into the life cycle of cicadas. He tells us why we will have a massive amount of noise during the coming weeks from treetops all around us here in Indiana and other areas of the eastern United States. When the soil temperature reaches 64 degrees F at a depth of eight inches, the periodic cicada or Magicicada will start crawling out of the ground. In massive numbers, they climb up trees to molt. After molting, their bodies will be white as they unfold new wings. In a few hours, their bodies will harden, and the males will fly into the treetops and start singing to attract females.

After mating, the females will lay eggs in twigs with a saw-like egg-laying device called an ovipositor. After the eggs hatch, the nymphs will fall from the treetops and burrow into the ground, where they feed on sap from the tree roots. Seventeen years later, the nymphs will emerge and become adult cicadas repeating the cycle.

The cicadas are easy to see, good to eat, and plentiful in huge numbers. Birds, squirrels, and other insect-eating animals will gorge on the cicadas giving other insects a reprieve to recover their numbers. The soil around the trees will be aerated and enriched. The process will prune upper tree branches encouraging new growth.

In Indiana and many other states, the cycle is 17 years. In other regions, the periodic cicada or Magicicada has a 13-year cycle. Trying to explain how such a system came into existence by chance requires a tremendous amount of imagination. We suggest that cicadas are another example of wisdom built into the natural world by God to allow life to exist on planet Earth.

Solutions to the Mosquito Problems

One of the big problems that humans face is mosquito infestations. Most of us know that mosquitoes can carry serious diseases, with malaria being at the top of the list. It is essential to understand that the presence of mosquitos is not a failure in God’s design of the natural world. What are the solutions to the mosquito problems?

Most mosquito species are pollinating insects. Of the problem species, only the females draw blood, usually from decaying remains of animals. Before humans invaded natural habitats, mosquitos were less of an issue than in modern times. The larvae do not survive well in running water, and mosquitos are such weak fliers that even a slight breeze will keep them at bay.

The human response to mosquitoes has been badly misdirected. The most common response has been to spray areas with heavy doses of chemicals that kill mosquitos. The problem is that the spraying kills everything else as well. Pesticides do not discriminate between good insects and bad ones. Animals dependent on insects for food are radically affected by massive spraying. Since 1970, nearly three billion birds have disappeared from North America. The solution to mosquito problems is quite simple–let God’s natural agents control the mosquito population.

Dragonflies and damselflies are voracious mosquito eaters concentrating on mosquito larvae. Hummingbirds eat hundreds of insects every day. American bullfrogs have long sticky tongues designed to catch insects, and mosquitos are at the top of their list. Red-eared slider turtles are mosquito eaters, with one study showing a 99% drop in mosquito numbers in ditches where the turtles were introduced. Woodpeckers, warblers, and wrens all eat mosquitos. They are all solutions to the mosquito problems.

Mass spraying creates imbalances in insect populations and kills birds and animals that feed on mosquito larvae. The spray also has serious implications for humans who react to the chemicals, including some forms of cancer. Humans have contributed to the dilemma that mosquitos bring to all of us, but God has natural solutions to the mosquito problems.

Murder Hornet Madness

The media can stir up unfounded and destructive emotional reactions to what, in reality, are minor events. In May of 2020, the media announced that Asian giant hornets (Vespa mandarinia) hornets had been found in Washington State and British Columbia. The media referred to them as “murder hornets” and expressed the fear that those hornets would sweep across the continent, killing people with their lethal stings. That caused some panic, especially in the eastern United States, which could be called “murder hornet madness.”

The Connecticut Agricultural Experiment Station in New Haven had numerous calls from people who believed they had a murder hornet in their backyard. In all cases so far, the specimen turned out to be a European hornet, bald face hornet, robber fly, or cicada-killer wasp.

To quell murder hornet madness, here are the facts about the Asian giant hornets from Science News:

1) They hunt for honeybees, not people, and the concern is for the honey industry, not because they will kill humans. A few months ago, we posted about how the honeybees have devised a defense against them.

2) Their nests have all been destroyed.

3) Studies show that migration to the east is almost impossible because of the mountains and other natural barriers in the way.

4) None of them have been seen anywhere but in the coastal ranges of Washington state and British Columbia. That is 3000 miles away from the people calling their local entomologists claiming to see them in their yards or parks.

Expert entomologist Gale Ridge, who has been working on the Asian giant hornet issue, says, “The combination of half-listening and overdramatization of the facts by the media creates an anxiety driven stew.” There is a threat to honeybees, making it essential to prevent this invasive species from getting a foothold in North America. However, Asian giant hornets are not a direct risk to humans.

We need to realize that the media are trying to get viewers and readers. They often overlook or overdramatize the facts, even creating “murder hornet madness.” That is true not just in cases of natural phenomena but also in politics and religion.

Learning from the Natural World

One of the ways people discover new materials and new applications is by learning from the natural world. Scientists have wondered how bugs that live in wet areas avoid water damage and bacterial infections. Researchers are using a fabrication process called nanoimprinting lithography to study the wings of Neotibicen pruinisus, the annual cicada found in the central region of the United States.

Cicada wings are made of a complex pillar-shaped nanostructure that repels water and prevents bacteria from establishing a foothold. New fabrication tools have enabled scientists to produce replicas of the wings and pillars. Entomologists at the University of Illinois at Urbana-Champaign have reported that this work will be beneficial in engineering applications across various subjects–everything from aircraft wings to medical equipment.

We look at what we feel are simple forms of life and fail to realize the complexity of their design. Earth is full of examples like the Cicada. Researchers are learning from the natural world. Everywhere we look, we find a wonder-working hand has gone before to allow life to exist all over the planet.

When God wanted to convince Job of His intelligence, power, and design (Job 38-41), He used astronomical and geologic creations and the design of an assortment of living things. Job responded by saying, “Surely I spoke of things I did not understand, things too wonderful for me to know” (Job 42:3). We must continue learning from the natural world God created because there is still much we don’t know. That is not just true of the material world but also of the spiritual world as well.

The Wonder of Birds

We live on the edge of the St. Joseph River in Michigan. By the river and surrounded by woods, I have the joy of observing the wonder of birds in enormous varieties. As I watch geese, swans and ducks take off and land on the river, I am amazed at the way they put their feet out and water ski to a stop. I enjoy seeing them stand on one foot, seemingly asleep with half of their bodies ready to react to any danger.

When our resident bald eagle flies by 100 feet above the water, the ducks turn their heads to track the eagle. The eagle swoops down and picks up a small dead fish which I couldn’t see from 20 feet away. I watch three species of woodpeckers hammer away at the trees on the edge of the river with such force that bark flies in all directions. Still, the design of their skulls lets them do this for hours on end without brain damage.

I watch the finches and nuthatches pick off berries from the poison ivy and eat them in the dead of winter. They never have any problem with the oil that I am allergic to. I watch the hummingbirds come to my feeders and hover for a long time, eating the sugar solution and engaging in territorial combat. I hear the birds singing as they mark their territories, with each species having its own peculiar melody.

As a person trained in physics and chemistry, I am enthralled by the wonder of birds and their widely varied properties. The Cornell Lab of Ornithology has an ongoing study of the properties and abilities of birds. One area of research is the specialized equipment individual bird species have. The eagle’s eyes are incredible optical tools that give it the ability to see a small fish from 100 feet above the water.

Woodpecker heads show engineering with their shock-absorbing design to prevent brain damage from the constant hammering they use to get bugs. People researching flight techniques study the wing design of hummingbirds which allows them to hover. The design of the bird’s gut prevents the poison ivy oil from lingering long enough to cause a reaction.

All birds have design features that allow them to survive. Their digestive and waste removal systems avoid the use of a bladder. The vascular system with a unique heart design allows the Swainson’s thrush to travel 3000 miles in a single flight with its heart beating 840 times a minute. Darwin showed us that the design of the bird genetics is flexible enough to allow their beaks to vary depending on what diet is available in their environment.

Humans throughout history have depended on birds as a food source. Where would we be in America without chickens and turkeys? God sustained the ancient Israelites with quails, a provision that continues today in that part of the world. In some areas, songbirds are a source of meat even though they are small. For those of us who look for evidence of God’s design in the natural world, birds are an incredible example of how much has to be done to produce an animal that can do what birds do.

The wonder of birds is not reasonably explained by accidental change. We all need to be concerned about the fact that between human exploitation, the removal of resources and habitat by humans, natural climate change, and pollution, the population of birds on our planet is getting smaller and smaller. Since 1970, three billion birds have vanished from the United States. God told us to take care of the world in which He has placed us. Caring for all of God’s creatures, including birds, is everyone’s responsibility.

Stop the Killing of Bees

There are many things that God has provided that we take for granted, and yet without them, we would not be able to live on planet Earth. One example is the common bee. The Earthjustice organization has been involved in trying to stop the killing of bees, and they gave some interesting statistics.

Bees fly an average of 55,000 miles (88,000 km) to produce one pound of honey. They can see colors that humans can’t see, and they communicate by dancing. Very importantly, it’s hard to realize that one-third of our food crops are dependent on bees. It takes 60,000 bees to pollinate one acre of an orchard, and without bees, we would have no almonds, apples, apricots, squash, and many other fruits and vegetables. An average hive contains about 30,000 bees.

One problem is that every year farmers apply over 5.6 billion pounds of pesticides to our country’s crops, and that is a factor in the decline of the bee population. The current alarm over the drop in the bee population is an excellent time to remember that God provided bees, not just for honey. They also sustain the food crops we need. That is why we must stop the killing of bees.

God Positioning System and What it Means

The Spring 2021 issue of God and Nature published an article by Angie Cornwell about the “God Positioning System.” During World War I, a homing pigeon saved the lives of almost 200 American men by carrying a message 25 miles despite being bombarded with gunfire. People have used homing pigeons for thousands of years to carry messages in all kinds of terrain, all kinds of weather, and in unfamiliar territory. Studies of how homing pigeons do this have concluded that they use at least five different systems. If one method doesn’t work, they use a different one. One technique is visual, using familiar landmarks. A second involves the use of environmental odors. A third system consists of using Earth’s magnetic field. A fourth system uses infrasonic (low frequency) signals, and a fifth system uses information stored in the pigeon’s brain.

Humans have a difficult time learning how to navigate in unfamiliar environments. For most of my life, I have relied on maps, but they are hard to use. You have to know where you are on the map, and folds in the map can cause misinformation. The invention of the global positioning system (GPS) has eliminated the weaknesses of maps. When in our human arrogance, we think we have a better way than the GPS has advised, causing us to get lost, the GPS will jump back in and guide us back to where we wanted to go.

Christians have a special GPS which Angie Cornwell has called the God positioning system. There are many similarities to the global position system. The God positioning system finds us wherever we are in life and directs us to where we need to go. When our arrogance causes us to choose a destructive path, we can turn back to the God positioning system to find our way.

God, in His mercy, has given us the ultimate navigational system to find our way back to Him. He has given us His Word to follow and His Holy Spirit to guide us. The global positioning system uses three satellites to triangulate our position. God the Father, Jesus Christ, His Son, and the Holy Spirit can pinpoint our spiritual condition and navigate us toward our eternal home. We never have to be desperately lost or alone. We don’t have to struggle to figure out where we are and how to get where we need to be.

Science hasn’t completely figured out all of the things that allow homing pigeons to navigate, and our human wisdom does not allow us to comprehend how the God positioning system works. The good news is that we don’t have to understand either one to take advantage of all they do for us.
