A Grass Called Wheat and the Bread of Life

The cultivation of a grass called wheat (Triticum aestivum) reaches far back into history. That grass became one of the first domesticated food crops and has been a primary staple food for people ever since. Today, wheat is grown on more land area than any other commercial crop and continues to be an essential food grain source for people. As a result, world trade in wheat is higher than for all other crops combined.

Although small, a wheat kernel has three main parts that enable it to feed the world. The source of white flour comes from the endosperm, which makes up about 83% of the kernel. Bran is the outer coat of the kernel, making up about 14%, and provides an excellent source of fiber. The smallest part of the kernel is the germ. It makes up only about 2.5% of the kernel and stores the embryo. People who mill flour separate the germ from other parts of the wheat kernel because it contains fat that limits flour’s shelf-life.

The endosperm of the wheat kernel contains a protein called gluten. It allows bread dough to rise by trapping minute bubbles of carbon dioxide when fermentation occurs in the leavened dough. Unfortunately, a small segment of the world’s population has to avoid eating gluten because of gluten sensitivity or a more serious autoimmune disorder known as coeliac disease. However, wheat is the most nourishing of the cereal grains, containing vitamins, minerals, carbohydrates, and fats to make a highly nutritious combination.

The grass called wheat is mentioned many times in the Bible, from Genesis to Revelation. Jesus referred to wheat in His parables and used it to illustrate principles in other ways. For example, people use wheat to make bread, and Jesus referred to himself as the Bread of Life. For thousands of years, wheat has been a vital part of the human diet, and the need for it only becomes greater as the population grows. Likewise, people worldwide need Jesus, the Bread of Life, who can teach us how to live in peace, give us meaning and purpose in life, and bring us into a relationship with God.

Why Would a Good God Create Viruses?

Think of the many illnesses that viruses cause, such as rabies, polio, Ebola, measles, mumps, yellow fever, influenza, HIV, chicken pox, hepatitis, shingles, rabies, and, of course, COVID. That is only a partial list. Some skeptics use this as an argument against the existence of God. Why would a good God create viruses?

Viruses are diverse and abundant beyond what we can imagine. The truth is that life on Earth could not exist without them. Even though many of them cause harm, they are essential tools in God’s construction of life.

By the usual definition of life, viruses are not alive since they cannot reproduce on their own. Instead, they must enter a living cell and coopt its replication functions to produce more of themselves. First, they hijack the 3D-printing machinery of the cell that turns genetic information into proteins. Then they damage the cell as they break out and spread to other cells. At least, that’s what happens in the case of the diseases mentioned. In COVID, the damage is to the victim’s respiratory tissue cells. So, why would a good God create viruses?

Viruses are present in every species of living creatures. They can be considered parasites, but sometimes they are in a symbiotic, or mutually beneficial, relationship with their host. They may remain dormant or even contribute to adaptive benefits. Problems often arise when a virus from one species enters another species. That is what happened with COVID and many other viral diseases. Most of them are known to have come into the human population from animals.

Scientists have only recently discovered that some viruses serve as food for certain microbes. They found that a single-celled microbe in the genus Hateria can live and grow on a virus diet, eating up to a million viruses per day. In turn, microbes are eaten by larger plankton which are consumed by larger predators which find their way into the stomachs of ever larger creatures going up the food chain to sustain life.

In addition to viruses contributing adaptive benefits to their hosts and providing food for microbes, they also serve other ecological roles. For example, some viruses infect algae. Algae blooms harm marine life, but the invading viruses help to control these aquatic algae blooms. Scientists have also found that viruses have contributed genes to human DNA that assist in embryonic development and help us resist infections and even fight off cancer.

So there are answers to the skeptic’s challenge, “Why would a good God create viruses?” Viruses are not evil, but they are a reflection of the design of the world in which we live. Their complexity allows them to shape and mold every aspect of the design of life.

Human Metabolism and Food Energy Production

Some say that the human body is no different from the bodies of other mammals, and in some senses, that is true. We all have hearts, stomachs, livers, etc., and our body chemistry is pretty much the same. If that were not true, we would be unable to eat meat or maintain a body temperature different from our environment. Still, despite these similarities, there are huge differences between human metabolism and the way we produce the food energy our bodies use.

For our body size, humans consume more calories each day than any other mammal. Evolutionists attempt to relate humans to chimps, gorillas, and orangutans, but the way humans handle food energy is radically different from the apes. When a baby human is born, its metabolism is very similar to an adult human, but it skyrockets over the first year of life. By the first birthday, toddlers burn over 50% more energy than we would expect for their size. Much of this consumption is to develop the brain. Throughout childhood, human metabolism will decline, reaching adult levels at around age 20, with boys declining more slowly than girls. After that, the energy expenditure is steady from age 20 until about age 60, and then it declines again.

Chimps, gorillas, and orangutans foraging for food can obtain between 200 and 300 k/cal each hour. At that rate, it takes apes about seven hours of foraging to get the k/cal they need for the day. Human metabolism requires more k/cal per day – around 2000 for women and 2500 for men, depending on body mass, activity, and age. Human hunter-gatherers can easily bring in 3000 to 5000 food k/cal per hour. Farmers produce much more than that. Until the middle 1800s, more than half of America’s workforce were farmers. Since humans have not had to spend so many hours obtaining food, we have time to devote ourselves to science, medicine, teaching, and the arts.

Human efficiency of food production allows children the freedom to grow and learn without spending every waking hour finding food. The problem we have involves food distribution and food waste. Our bodies are amazing machines of human metabolism. Herman Pontzer of the Duke Global Health Institute wrote, “The human body is a wonder of coordinated chaos. Every second of every day, each of your 37 trillion cells is hard at work, pulling in nutrients, building new proteins, and doing the myriad of other tasks that keep you alive.”

The human body is uniquely designed to serve others and serve God. That fact led the Psalmist to write, “I will praise you, God, for I am fearfully and wonderfully made. I know that full well” (Psalms 139:14). It also speaks to the value of human life and the importance of living as God has called us to live.

Emotional Tears Are Different from Other Tears

In 1662 Danish scientist Niels Stensen discovered that the lacrimal gland in the corner of each eye is the source of our tears. Human eyes produce three different types of tears, each with different purposes. Basal tears clean and lubricate the eyes. Responding to environmental stresses produces reflex tears. For example, we experience this kind of tears when we cut an onion. The third type is more mysterious. Emotional tears are different from other tears.

One difference is that we have some control over emotional tears. Secondly, they contain hormones and proteins not found in other tears. The proteins cause them to stick to our faces. Thirdly, researchers suggest that they are useful in confirming to others that we are truly happy or very sad. For example, watching a “tearjerker” movie causes us to produce emotional tears.

Emotional tears are different from other tears since only humans release emotional tears in moments of sorrow or joy. They are a way of communicating and sharing our emotions. The limbic system in the brain, which is associated with emotional arousal, triggers the brain’s message station (pons) to signal the lacrimal system to produce tears. No other animal produces emotional tears.

Researchers believe that emotional tears are a social cue to other humans to indicate that we need help. Babies don’t have fully developed lacrimal glands, so they can’t produce visible tears. Instead, they audibly cry when they need attention. As humans mature, emotional tears indicate a broad range of needs and feelings, including compassion, empathy, and sentimental or moral feelings.

People who shed emotional tears and receive support from others feel better. Holding back the tears or not receiving social and moral support leaves a person feeling less satisfied. Emotional tears are different from other tears because they can bring us together for spiritual and emotional healing. As humans, we have unique needs because of our relationship with each other and with God. That is one of the many factors showing that God created us in His image.

Global Biomass and Human Responsibility

You may be surprised to know that the total biomass of bacteria in the ground is 1000 times more than the mass of humans. Mass is the total number of molecules present, and we usually measure it by weight, which is the pull of gravity on the molecules. For example, the mass of living things in the ocean equals 100 times the mass of all humans on planet Earth. In other words, if you totaled the quantity of matter in whales, fish, corals, clams, etc., you would have 100 times more molecules than in all living humans. If you counted the number of individual life forms in the oceans, the ratio would be even greater than 100-to-one, but that is quantity, and we are talking about global biomass.

Not only is the mass of underground bacteria greater than that of humans, but even worms have three times our mass. Even more surprising, the mass of viruses on Earth exceeds human mass by more than three times, and the global biomass of all bacteria is more than 1100 times that of all humans. There are some important messages in these numbers. One is that we must understand that we can’t eliminate viruses or bacteria in the world. Furthermore, we wouldn’t want to. Bacteria and viruses are essential in sustaining all other forms of life.

Another thing we need to consider is that humans keep (as livestock, poultry, and pets) a third of all mammal biomass on the planet and two-thirds of all bird mass. In Genesis 1:28, God gave humans the responsibility of managing all living things. We are now beginning to understand the importance of the conservation and management of life on our planet.

The global biomass of plants is another area where we have had a poor understanding. The mass of all plants is 7500 times greater than human mass, and like bacteria and viruses, plants are essential to life on our planet. Human destruction of forests worldwide and the replacement of vegetation with concrete are major factors in pollution and climate change.

The Genesis account says, “I give you every seed-bearing plant on the face of the whole earth, and every tree that has fruit with seed in it. They will be yours for food. And to all the beasts of the earth and all the birds of the air and all the creatures that move on the ground – everything that has the breath of life in it – I give every green plant for food” (Genesis 1:29-30). Earth’s design is no accident. The role of plants, bacteria, worms, viruses, and all life is a product of an infinitely intelligent and understanding mind.

The dictionary definition of “science” is “knowledge,” and it can never conflict with the mind that created all we see and are. When God challenges us to consider the wisdom in the creation, the human response is like Job’s, “Surely I spoke of things I did not understand, things too wonderful for me to know” (Job 42:3). We know a lot more than Job did, but, like him, there is much we don’t know.

Dinosaur Tracks and Human Tracks

For many years, various religious sources have claimed that dinosaur tracks and human tracks exist in the same rock strata in Glen Rose, Texas. We have visited the site several times and have published articles on the tracks. Our studies were not just at Dinosaur Valley State Park, operated by the state of Texas, but also at Jake McFall’s ranch, where the original film “Footprints in Stone” was made fifty-plus years ago. The dinosaur tracks are very clear, but the human tracks are what today we would call “fake news.”

The area near Glen Rose, Texas, has been in a drought, and some of the Paluxy River dried up, exposing the new tracks. There are now five dinosaur track sites in the park. The tracks show the depth that the animal’s feet sank into the mud, which was part of a beach area in the dinosaur age. The depth of the tracks and how far they are separated from each other suggest that the animal was bipedal and very large. Researchers say that the dinosaur was an Acrocanthosaurus.

Some have claimed there are dinosaur tracks and human tracks in the same rock layer, attempting to prove that dinosaurs and humans lived at the same time. However, the claimed human tracks are impressions in mud that were altered by the river and then painted by those who claim they are valid. They also sink the same depth into the ground, suggesting that the “humans” were the same weight as the dinosaur, which is impossible. Furthermore, researchers have found no human tracks anywhere in the same rock layer as dinosaur tracks.

We have suggested that dinosaurs were part of Genesis 1:1 and God used them to prepare the resources humans would need. Dinosaurs are not described in the Bible because the ancient Hebrews could not have comprehended their existence. People who believe the Bible must be careful not to employ the same fake news techniques frequently used in politics. Claiming that dinosaur tracks and human tracks prove that they lived simultaneously is a dispensational denominational religious view the Bible does not teach.

God’s word is true, but we must rely on valid evidence as we seek to support it as a guide to understanding history and knowing how to live our lives.

Can Evolution Explain Life?

Over the past two days, we have considered dinosaurs and the age of planet Earth. Some suggest that accepting that Earth is ancient means that evolution explains life. Can evolution explain life? “Evolution” is a very broad term that can mean many different things. However, we have said before that evolution can’t explain everything. Here are some links to examine:

I Believe in Evolution

Evolution Has Multiple Meanings

Evolution Is Not Creation

Human Evolution from Lower Life Forms

Fossil Apes and Human Evolution

Biological Barriers to Evolution

Evolution Does Not Explain Creation

These links are only a sample of the many articles we have published on the topic of evolution. You can go to our DoesGodExist.today website and use the search box to find articles on this or other topics. Can evolution explain life? The short answer is “no.” Naturalistic evolution also cannot explain the apparent design we see in nature, and we will deal with that tomorrow.

Recursive Sequences and Language

One of the most interesting differences between animals and humans is language. All animals communicate, and most animals that humans relate to use sounds to facilitate their communication. In recent studies, researchers have suggested that the use of recursive sequences by monkeys and crows is a type of language. However, communication and language are not the same.

The dictionary definition of recursive is “doing or saying the same thing several times in order to produce a particular result.” The newest research shows that crows and monkeys use recursive sequences at a level comparable to what a three or four-year-old child would do. There are a variety of explanations as to why these animals use recursive sequences, but this does not mean that crows and monkeys are using language or that they possess culture or express identity.

A woodpecker likes to pound on the flashing of my chimney with such enthusiasm that people can hear it throughout the neighborhood. This is communication warning all other woodpeckers to stay out of his territory. Likewise, the cardinal that sits in a bush near my office window “sings,” but the song is a warning, not an expression of language or music.

The dictionary defines language as “a system of conventional spoken, manual (signed), or written symbols by means of which human beings, as members of a social group and participants in its culture, express themselves. The functions of language include communication, the expression of identity, play, imaginative expression, and emotional release.”

The Bible defines humans as beings uniquely created in the image of God. This is a spiritual definition and does not involve intelligence or skills. We see the spiritual nature of humans in a variety of characteristics. Those include our creative ability in art and music, self-concept and recognition, and the ability to feel guilt, sympathy, and empathy. Those are all manifestations of the spiritual nature of humans. Recursive sequences may or may not be among these characteristics, but they are not a singular indicator of being human. Because of our spiritual nature, humans also have the capacity to worship and envision life beyond death.

Difference Between Pain and Suffering

One of the attributes unique to humans is the ability to suffer. You may think the words “suffering” and “pain” are synonyms, but they describe different things. The difference between pain and suffering demonstrates the uniqueness of humans.

Pain is a physical characteristic of almost all living things. It is easy to show that when a nervous system experiences a violent stimulus, it produces an electric signal. For animals, the nervous system is connected to a muscular system that frees the organism from damaging stimuli. This design is present in all members of the animal kingdom to protect them from being wiped out by predators or destructive environmental agents.

The difference between pain and suffering shows us that suffering is a different response and serves a different purpose. Romans 8:16-18 tells us that Christians are joint heirs with Christ and that Christians will suffer with Christ. This means that “the sufferings of this present time are not worthy to be compared to the glory which shall be revealed in us.” It is obvious that not all Christians have been physically crucified as Jesus was.

In 2 Corinthians 1:5-7, Paul writes, “For as the sufferings of Christ abound in us, so … we endure the same sufferings … for your salvation and our hope for you is knowing that you are partakers in the suffering.” In Philippians 3:8-10, Paul says that he has suffered the loss of all things and refers to the fellowship of His sufferings. In Colossians 1:24, Paul talks about his sufferings for the church in Colosse. Hebrews 2:10 refers to Christ enabling his followers to be made perfect in their salvation through sufferings. Christ himself, according to Hebrews 5:8, “earned obedience by the things he suffered.” This theme is repeated in 1 Peter 1:11, 4:13, and 5:10.

The context of all of these passages is clear. There is a difference between pain and suffering. We are not talking about physical things like being burned, scourged, tortured, or beaten. The early Christians did endure those things, but that is not what the passages above describe.

The simplest example of the sufferings described is what we endure when we have what we call a broken heart. Having heartbreak does not refer to something physical. Most of us who have had our hearts broken would be glad to take a beating instead. A physical beating does not last long. I have had physical pain from a beating, but that pain is a distant memory. The heartbreak of watching my wife die is still heavy upon me, even though it happened more than a decade ago.

Being a Christian in today’s world shares some of the sufferings that first-century Christians endured. Some of us have suffered being rejected and disowned by family. Others have lost good jobs because of their faith. Speaking out in favor of Christ and Christianity, in general, can result in verbal abuse, ridicule, ostracism, exclusion, and rejection. This suffering is real and scars you emotionally and sometimes spiritually.

Animals do not show any evidence of the kind of suffering we have described. Animal behavior is based on food and instinctive drives to reproduce. Guilt, empathy, and sympathy are not part of animal behavior. Claims of grief in animals such as elephants may or may not be real. If it is real, it is based on the social structure of the pack or group and not because the animal is suffering from the memory of a loss that will extend for the rest of the animal’s life.

We can see the difference between pain and suffering in humans because we have a unique spiritual makeup that allows suffering and enables us to relate to the suffering of others. Because we are created in the image of God, we can understand how an agape type of love is possible. That is why Christianity is the one hope the world has for the peace of all people. Your soul suffers, and this suffering can last a lifetime. We need to help animals avoid pain, but human empathy is what may someday foster world peace. That hope is always before us and is unique to humans.

Observing Fibonacci Day

Humans look for ways to celebrate certain days. We laugh at Groundhog Day and use Valentine’s Day for special human relationships. Some days have extensive significance, such as Thanksgiving, Christmas, or Veteran’s Day. We are now observing Fibonacci Day on November 23. Fibonacci Day is an unusual celebration of a remarkable mathematical sequence.

Fibonacci was an Italian mathematician who noticed in the year 1202 some interesting oddities about a particular sequence of numbers: 1,2,3,5,8,13,21,34,55, 89,144, 233. Notice that when you add any two sequential numbers, you get the next number. For example 5 + 8 = 13; 8 + 13 = 21; etc. If you divide two sequential numbers, you get .618034, which some mathematicians have called the “golden mean.”

Applying this Fibonacci sequence to architecture, you get a practical application. A rectangle using any two sequential numbers is aesthetically pleasing to human eyes. If you cut a square off any of these rectangles, you get another rectangle with the Fibonacci sequence. If you connect the corners of the squares in a series of Fibonacci rectangles, you get a spiral (see sketch).

An amazing thing about this is that there are an unlimited number of examples of Fibonacci spirals in the natural world. A small sampling includes:
*The spiral arms of galaxies curl in a Fibonacci spiral.
*The curl of a wave in the ocean fits the Fibonacci spiral.
*The snail shells curl in a Fibonacci curve.
*Elephant tusks curve in a Fibonacci spiral.
*The roots of human teeth curve in a Fibonacci spiral.
*Spider webs fit the Fibonacci spiral
*Keys on the piano are 5 black and 8 white, 13 in all, fitting the ratio.

*Musical chords producing pleasing sounds have the Fibonacci ratio.
*Bacteria growth curves fit the Fibonacci ratio.

There is no natural or evolutionary reason for the Fibonacci sequence. Notice it isn’t just in one discipline but in widely separated areas of study.

The Fibonacci Association publishes a magazine called the Fibonacci Quarterly, and people have written several books about the Fibonacci ratio. If you are observing Fibonacci Day, realize that this demonstrates God’s design in the creation. Chance does not produce a pattern across multiple disciplines like this.
