How Humans Avoided Being Eaten by Carnivores

Have you ever considered how humans avoided being eaten by carnivores in ancient times since we are essentially defenseless? We aren’t stronger than large carnivores, have no teeth or claws for defense, can’t run very fast, and do not have camouflage. So if you believe in survival of the fittest, it is pretty obvious humans should not have survived.

The research done by scientists reveals some incredible planning that allows us to exist. Consider these facts:

1) Human color vision is unique from that of other animals. For example, carnivores have dichromatic vision with two color cones, while humans have three. Hunters can wear red and not spook their prey because the prey does not have red cones.

2) Human vision has better angular resolution than other animals allowing greater spatial processing. We can tell where an animal is long before it can see us. When you walk your dog, you can see another dog long before your dog does, and you know how far away it is.

3) Humans have group behavior and group communication. Our speech lets a group know what the carnivore is and where it is. Our brains have sound and behavior connected. Carnivores have blind-deaf disembodied brains, meaning that sight and sound are not connected in a carnivore’s brain. Seeing a human or hearing one does not tell the carnivore whether the human is a useful food source. In addition, a carnivore would have to fight a group of humans prepared for its attack, requiring more energy to track down than the energy it would get from eating one of us.

Studies by biologists have shown that if zebras and antelopes had the same visual and sound connections to their brains as humans, lions would starve to death. So God’s design is how humans avoided being eaten by carnivores that are stronger than us. These features, and our intelligence, allowed us to survive.

After the flood, God told Noah, “And the fear of you and the dread of you shall be upon every beast of the earth, on every bird of the air, on all that move on the earth, and on all the fish of the sea. They are given into your hand” (Genesis 9:2). So that is how humans avoided being eaten by carnivores. God designed the life system, including the animals that physically could use man as a food source, in a way that humans could exist. We are unique in our spiritual makeup in God’s image and in our physical bodies designed for survival.

Design in the Insect World

We can find some of the most incredible demonstrations of design in the insect world. Survival in places where very cold winters exist presents a challenge for Insects. Some can bury deep underground, but that is not always practical. Another method of avoiding being wiped out by freezing temperatures is migrating to warmer areas for the winter.

The painted lady butterfly (Vanessa cardui) is one of the most common butterfly species in the world. Researchers knew that painted ladies in Europe fly over 9,000 miles (15,000 km) across the Sahara desert to winter in Africa. But, until recently, they didn’t know precisely where these butterflies go. Now scientists have learned that they live and breed in the savannahs and highlands of central Africa.

Painted lady butterflies from Europe spend their time in semiarid savannas from September to November. When those areas become too dry, they head further south to the savannas and highlands across central Africa for December to February. They avoid tropical rainforests because they are too humid for these insects. Like monarch butterflies, they go through multiple generations before the adults journey back to Europe in the spring.

The researchers who studied this incredible migration have learned where the painted lady butterflies go. However, questions remain unanswered. For example, who told these butterflies to make this long journey, and how do succeeding generations know to make the same trip? Most of us in North America are familiar with monarch butterflies and their impressive migration to Mexico. Still, the migration of painted lady butterflies is the longest journey of any butterfly.

God’s design for the survival of all creatures speaks of His wisdom and planning. When we see the design in the insect world, we appreciate the wisdom and power of God, who has entrusted us with protecting all of His creation.

The Purpose for Human Existence

“Why do I exist?” People have discussed and debated the purpose for human existence from about every philosophical direction imaginable. Atheists have written books to tell us that we are just accidents with no purpose for existence. Many theologians give the trite answer, “Because God wanted to create us,” which is not much of an answer.

Recent evangelical ministers have used the analogy of couples deciding to have a child. If a child asks his parents, “Why did you have me?” What would they say? They might say, “Because we wanted a child to love.” Later, a parent might say their child has brought them great pride as they tell anyone who listens, “That’s my child.” Does that human parent comparison explain why God created us?

I would consider that it is not reasonable to suggest that we humans fulfill a need that God has. God does not have human needs. We don’t praise God because He has an ego problem or is struggling with depression. The Apostle Paul tells us to “glorify God” in Romans 15:6 and elsewhere, but that does not mean God needs us to build Him up because He lacks something. That would be like a political figure or an entertainer who needs people to praise him and build his esteem. Thinking that God has such needs is rooted in human attempts to create God in our own image.

In the Bible, we can find clues to help us understand more clearly the purpose for human existence. For example, the book of Job shows a conflict beyond our daily physical struggles. God never explained to Job the spiritual battle behind the purpose for his existence and which led to the pain he suffered. But after his dialogue with God, Job concluded that the answer is beyond human knowledge or understanding. Speaking through Ezekiel, God tells us that Job, Noah, and Daniel achieved the purpose for which they were created, but their righteousness could not make up for the sins of others. (See Ezekiel 14:14 and 20.)

The New Testament further clarifies the purpose for human existence. First, we see a major confrontation in the war between good and evil in Matthew 4:1-10 when Satan tempted Jesus. Then we see the culmination of the conflict in Revelation 20-22. People often fail to understand the Book of Revelation because they don’t understand that it is not describing a physical war. The war between good and evil is in a realm beyond this physical world. Ephesians 6:10-20 makes it clear that the purpose of our existence is beyond flesh and blood but involves a struggle “against the rulers, against the authorities against the cosmic powers over this present darkness, and against the spiritual forces of evil in the heavenly places.”

In Ephesians 3:8-13, Paul writes that his purpose in existing was “to bring to light for everyone what is the plan of the mystery hidden for ages in God who created all things, so that through the Church the manifold wisdom of God might now be made known to the rulers and authorities in the heavenly places. This was according to the eternal purpose He has realized in Christ Jesus our Lord.”

Revelation chapters 20 to 22 give a prophecy of the ultimate destruction of evil and the wonderful existence we all can have if we fulfill the purpose for which God created us. First, John 1: 5-9 makes it clear that we will not be perfect, but we will be forgiven and cleansed as we fulfill the purpose for human existence. Atheists try to tell us that evil doesn’t exist and that there is no reason for us to be here. However, the evidence and the biblical message show us the reason for our existence and the joy and love God makes available to us all.

Relativity, Quantum Mechanics, and Complex Electron Orbitals

Yesterday, we said that the simple atomic model shown in older chemistry textbooks leaves many mysteries unanswered. During my 50 years of teaching chemistry, students sometimes asked questions that could not be explained by electrons in circular orbits. In recent years, spectral analysis has shown that electrons travel in various orbital patterns that may be dumbbell or clover-leaf shaped. In addition, quantum mechanics has shown that electrons can act like waves rather than particles. Relativity, quantum mechanics, and complex electron orbitals explain some of the mysteries of chemistry.

For example, oxygen has a first shell with two s-type electrons traveling in circular orbits and four more in dumbbell-shaped p orbits. That second shell can hold six electrons, leaving openings for two more orbitals 90 degrees apart. If a hydrogen atom with one electron comes nearby, it will bond with the oxygen, each of them sharing an electron. If two hydrogens bond with the oxygen atom, you have a perfect, stable combination – a water molecule.

In the water molecule, the hydrogen atoms repel each other, creating a 180-degree angle between them and giving the water an electrical polarity. The result is that water molecules have a positive and negative end, and as they freeze, they repel each other, expanding their volume. Because of that, ice is less dense and floats on top of the water instead of sinking to the bottom. If bodies of water froze from the bottom up, life on Earth would be impossible.

What makes this picture even more interesting is that electrons can orbit at a speed that is 60% of the speed of light or faster. At that speed, their mass increases, and their orbit contracts in conformity with Einstein’s relativity equations. Relativity, quantum mechanics, and complex electron orbitals combine to explain the mysteries of chemistry. For example, the relativity contraction makes it harder for mercury atoms to interact strongly with each other. As a result, mercury is a liquid, while other metals are solids at room temperature.

Relativity and quantum mechanics also explain the difference in color between gold and silver. Relativistic effects in the electron orbitals cause silver to reflect all wavelengths of visible light equally. Because of that, it has no particular color. On the other hand, gold’s electron orbitals cause it to absorb blue light, making the reflected light appear yellow.

Relativity, quantum mechanics, and complex electron orbitals are opening new understandings in chemistry, allowing new techniques to aid in improving life for all humans. For example, doctors use radioactive technetium and rhenium as tracer molecules in medical imaging because of the effects of relativity. Understanding relativity and electron orbitals explains the formation of lead dioxide, which is essential for lead-acid auto batteries. Relativity in electron orbitals even plays a role in “glow-in-the-dark” items such as signs, stickers, and T-shirts.

The complexity of atoms is a testimony to the intelligence and engineering of the Creator. We are continually reminded that we can know there is a God through the things He has made. The challenges and the future of relativistic chemistry are a great testimony to that.

The Simple Atomic Model and Unanswered Questions

The Simple Atomic Model Leaves Unanswered Questions — This simple atomic model is not accurate

Our understanding of the design of the atom changed radically in the 50 years that I taught chemistry in public school. When I started teaching, scientists thought atoms were made up of a nucleus surrounded by electrons in circular orbits. This simple atomic model was easy to understand, and we had drawings and even plastic models to show it. However, the simple atomic model leaves unanswered questions.

The simple model did not explain the properties of certain atoms. For example, why is mercury a liquid at room temperature while other metals, such as gold, platinum, and lead, are solids, even though they have very similar structures? Why are gold and silver different colors? Why does water expand when it gets colder when all other materials contract?

As an old chemistry teacher, my students frequently asked questions I could not answer. Improvements in spectral analysis made the simple atomic model more complicated while answering some questions. For example, scientists could see that not all electrons travel in circular orbits. Also, electrons are not solid balls or even particles. Instead, electrons can be waves and have orbital paths that are spherical or shaped like dumbbells, clover leaves, or a mixture of those two.

Different orbital shapes cause different spectral patterns. As a result, scientists have coined the names “s” for sharp spectral lines, “p” for principle lines, “d” for diffuse lines, or “f” for fundamental lines. Moving out from the nucleus of an atom, the number of electrons increases, and their paths become more complex.

The more we learn, the more we see the wisdom built into the design of every atom in the universe. The precision of design makes it possible for life to exist. Minor changes would mean that we would not be here. However, the simple atomic model leaves unanswered questions and can’t begin to show the extent of God’s design wisdom. Applying what we know about relativity, quantum mechanics, and electron orbits answers some of the chemistry students’ difficult questions. We will have more on that tomorrow.

Understanding Animal Communication

We all remember the movie about a man who could uniquely talk to animals. Reports tell us that portable sensors and artificial intelligence may make a form of human-animal communication possible. Unlike that movie and the work of Penny Patterson using sign language to communicate with Koko the gorilla, the research goal is understanding animal communication instead of expecting them to use human language. Researchers use digital bioacoustics to record the animals and artificial intelligence to interpret what they say.

So far, scientists have studied the communication of bats and bees. Using tiny digital bioacoustic recorders, researchers at Tel Aviv University have gathered bat communication at frequencies above the limit of human hearing, over 20,000 hertz. Computers lower the frequency and slow it down to make it audible to humans, and artificial intelligence compiles the data to make it intelligible. Gerry Carter at Ohio State University has determined that bats have individual names, or “signature calls.” They argue over food, and mother bats communicate with their babies.

Understanding animal communication can involve more than sounds. Dr. Tim Landgraf at Freie Universitat in Berlin has deciphered bee communication, which involves both sounds and body movement. He has decoded the signals which tell other bees where to find nectar or warn of danger. Landgraf even built a robot name RoboBee that can enter a hive and control what the bees do. For example, when he put nectar in a place where no honeybee had visited and then told the bees where the nectar was, they went there.

Helping animals avoid pollution and directing them to safe food sources are potential applications of this technology. It is essential to understand the big difference between communication and language. These examples and future research with animals involve communication. Language is far more than communication and deals with culture, morals, and symbolism. As this field of understanding grows, its uses will also increase, and ethical concerns will become apparent.

One has to wonder how Adam and Eve communicated in the garden. They certainly did not speak English. Bat communication is obviously different from bee communication. Understanding animal communication is challenging since every animal is different, but that shows another level of design that science is just now beginning to understand. The more we learn about the creation, the more we have to be amazed at the wisdom of the Creator.

Make the Golden Years Fruitful

How we deal with old age is one of the things that distinguishes Christians from those who reject the Bible as their guide for life. Coming from a family of atheists, I have witnessed how they dealt with aging. I have watched my atheist friends use cosmetic devices and surgery to avoid the consequences of age. Of course, no cosmetic treatment or surgical procedure can remove the aches and pains that time brings, but following Christ can make the golden years fruitful.

For Christians, getting older is a time of growth in understanding and wisdom. In Philippians 3:7-12, Paul talks about looking back on things that he thought were important and considering them “rubbish” and that he “counts all things loss for the excellence of the knowledge of Christ Jesus my Lord.” We can make the golden years fruitful by following the positive teachings of Christ.

We read in Acts 17:19 about Paul bringing his message to the Areopagus, where older Greeks learned new things. Today our Areopagus is the web where we can share information and ideas. This ministry reaches people of all ages with the message that science and faith are symbiotic. Our websites contain a wealth of new understandings. In addition to this site, please check out doesgodexist.org and doesgodexist.tv. Maturity allows us to challenge our old misunderstandings and learn new things. Biblical examples include Apollos in Acts 18:24-28 and Paul in 2 Corinthians 12:2-9.

We can make the golden years fruitful by repairing broken relationships. The Bible contains examples such as Jacob and Esau in Genesis 32-33, Joseph and his brothers in Genesis 45:4-5, and Jesus and Peter in John 21:7-17. Maturity is a time to overcome stubbornness and forgive. Jesus called His followers to forgive, but non-believers sometimes carry grudges to their graves. I have seen this happen in my family and friends who didn’t have a Christian basis for forgiveness.

The most significant benefit of being an older Christian is having a purpose in life. I have watched family members who retired from their secular employment or lost a spouse and had no life purpose as they died mentally, leading to physical death. Enjoying grandchildren, recreation, or hobbies lasts only so long. Having a purpose in life lasts right up to the end. Being a Christian in retirement allows me to devote much of my time and energy to the ministry that God has given me.

Matthew 25:31-46 lists things seniors can uniquely do to make the golden years fruitful. You can’t retire from God. Doing His will brings blessings beyond what the secular world can comprehend. Paul expresses this beautifully in 2 Timothy 4:6-22 as he looks back at his life, realizing it is about to end: “I am already being poured out on the altar, the time of my departure is at hand. I have fought a good fight; I have finished my course….” Don’t let age rob you of the blessing of purpose and usefulness.

Geological History Lessons

One of my favorite places on Earth is northern Michigan. As a child, I spent many summers on Lake Michigammi in the upper peninsula and grew to love the land of birches and pines. We can learn from the geological history lessons of northern Michigan.

Returning to this area over 70 years later has been a shock. When I was a kid, the people made a living harvesting and using the trees to make wood for construction purposes and to make paper. That industry still exists, but tourism and the construction of elaborate homes have replaced the trees as the basis of the northern Michigan economy. People have been buying large plots of land, building huge houses, and calling their property a “forest preserve.” Unfortunately, this practice includes the shoreline of Lake Michigan, Lake Huron, and the many inland lakes, limiting the general public’s access to this water wonderland.

Michigan’s state rock is the Petoskey stone, a beautiful coral often used to make attractive jewelry. The interesting thing about the Petoskey stone is that it is a tropical coral that only grows in warm water. Obviously, there has been a change in the climate because Michigan is not a tropical paradise. In our time of concern about climate change, we find the geological history lessons of northern Michigan indicating that Earth’s climate has changed in the past.

Another lesson from northern Michigan is the action of ice over time. Everywhere you look, you see huge rocks weighing many tons that could not have been placed by running water. These rocks come from many places and are all different. As a public school earth science teacher in South Bend, Indiana, I would take my students to the local gravel pit to hunt for unusual rocks. One student found a jasper conglomerate from Bruce Mines in Ontario. It had glacial groves and was hundreds of miles from its origin. We also found pieces of raw copper from outcrops in northern Michigan. One student found a diamond from an unknown Klondike area somewhere to the north. The geological history lessons we learn from the enormous rocks, the sand, and the many lakes is that, at one time, glaciers covered the area.

So how much time did these climate changes take? Knowing the geological history has been essential for oil drilling, coal and copper mining, and agriculture in Michigan. These things were part of how God prepared planet Earth for human habitation. Some religious people have tried to explain these things by Noah’s flood, but most ignore any attempt to explain the method and just say, “God did it.” That avoids the question of how and when.

Genesis 1:1 is undated and untimed, and the Genesis account uses the Hebrew words “bara,” meaning to create, and “asah,” meaning to make. Creating from nothing (bara) is used in verse 1, where it applies to space, time, and matter/energy. It is used again in verse 21 for the creation of the first life and in verse 27 for the creation of the first humans. Making (asah) refers to taking what was created and changing it. It is used in verses 7, 16, and 25. Chapter 2 verse 3 summarizes what God had done by using both bara and asah.

The geological history lessons of northern Michigan show us God taking what He had created and molding the Earth to prepare it for human habitation. As we understand more of what God has done, it becomes evident that all we see around us is the work of an intelligent Creator who cares about His creation and the humans He created in His image.

Eight Billion People on Earth

In November of 2022, the human population hit eight billion people. That means eight billion people need food, shelter, and energy for transportation and protection from the elements. In Genesis 1:28 and 9:1, God told Adam and Eve and later Noah and his family to “be fruitful and multiply.” Then the text uses the Hebrew word “mala” the Earth. Mala can mean fill, replenish, satisfy, accomplish, or confirm, according to Strong’s Exhaustive Concordance.

God’s command to early humans told them to take on the responsibility of caring for the planet. It does not mean their only purpose would be to have lots of children. God expects us to control and care for the creation, not merely endure its challenges. There is a fundamental difference between the biblical concept of our relationship to the planet and our present state, which has caused poverty and starvation.

The Christian system teaches a one-man/one-woman system of marriage as opposed to polygamy. It also teaches that being a father places responsibilities upon men. Passages like Ephesians 6:4 and Colossians 3:21 make it clear that fathering children gives men a responsibility to encourage and guide them.

The quality of life for Earth’s eight billion people depends on how we manage the issues of population control and caring for the environment. The teachings of Christ support the nurturing of the Christian family. The selfish and reckless placing of pleasure above all else brings pain to the individuals who embrace it and tragedy to human society. Promoting and following the Christian system of values is essential for human flourishing, and the collateral damage produced by not following it is becoming increasingly evident.

Use of Cannabis by Seniors

The use of marijuana to treat chronic pain and discomfort like arthritis has been widely publicized and legalized in many states. So naturally, those of us who are older look for any way to relieve the aches and pains that come with age. Because of that, the use of cannabis by seniors has increased dramatically.

Certainly, we should use anything God has given us to relieve human discomfort as long as it is not harmful. We must understand that one of God’s injunctions is to take care of the body, which the Bible says is the dwelling place of God’s Spirit (1 Corinthians 3:16).

We are responsible for ensuring that what we use to relieve discomfort is good for us and doesn’t harm our bodies. That means we must use caution and listen to research about so-called miracle cures. But unfortunately, new studies of the use of cannabis by seniors have raised a red flag about its safety.

The Journal of the American Geriatrics Society for January 9 reports on visits to emergency departments in California, where marijuana has been legal for any use for several years. Cannabis-related visits to emergency rooms by seniors (ages 65 and older) rose from 366 in 2005 to 12,167 in 2019.

Unfortunately, there is big money in the marijuana business, so cannabis merchants are promoting its use. However, you should use it under a doctor’s supervision. It should not be a matter of simply going to your local marijuana store and accepting all the claims they make for a “miracle cure” for whatever ails us.
