Do Animals Fall in Love?

Discover magazine carried a story titled “Fowls in Love” about two Canada geese nicknamed Arnold and Amelia. Many animals pair up to raise young or for protection. However, evolutionary survival of the fittest fails to explain animals sticking together when one of the pair becomes injured and unable to assist in survival. So do animals fall in love?

The Birdsey Cape Wildlife Center staff in Barnstable, Massachusetts, noticed the male goose limping. He had an open fracture that wouldn’t heal on its own. They caught Arnold and prepared to do surgery to repair his foot. The female goose observed the procedure through the clinic’s sliding glass door. When Arnold awoke from surgery, Amelia was allowed into the room, and she used her beak to preen his feathers. For the next 14 days, Amelia was at the center daily, sharing Arnold’s meals and spending time with him.

After Arnold was released, the staff observed the pair together for two weeks until they left with a passing flock of Canada geese. Do animals fall in love? The article writer concludes that the two geese were in love. The article ends with this statement by the veterinarian who did the surgery, “There has to be some internal motivating force that allows that animal to behave in a particular way, and we call it love – that internal driving force.”

This is a classic example of anthropomorphism, attaching human characteristics to an animal. The biblical concept of love is spelled out uniquely in the New Testament by the Greek word “agape,” meaning to consider the object of one’s attention to be of incredible worth. Jesus used agape in His teachings, and we find it in New Testament references to marriage. Human marriage is not just for survival.

We have numerous geese where we live on the St. Joseph river in Michigan. They are always in pairs, and getting near to one of them or their chicks invites an attack from the mate. Raccoons learn to avoid pairs but will go after an isolated goose or chick. Do animals fall in love, or is there a survival reason?

God has placed an instinctive drive in geese to maximize their chances of survival and success in raising young. The bond between Arnold and Amelia demonstrates how strong the instinctive drive is. It is not the biblical concept of love. When Jesus tells his followers to love their enemies and not resist evil (Matthew 5:38-45), He tells them to do something animals cannot do.

Each Octopus Arm Moves as if it Has its Own Brain

What does it take to enable an octopus to use all eight arms efficiently? Each arm may be in contact with a different substance, and they are soft and pliable, so they can bend and twist in response to whatever stimuli they receive. As a result, each octopus arm moves as if it has its own brain.

Researchers recently discovered that the arms gather data and move independently or with other arms without consulting the octopus’s brain. The octopus has a central brain connected to a nerve ring that connects to each arm. In addition to the arms’ connections to the brain, a nerve connects each arm to another, located two arms away. This arrangement allows each arm to communicate directly with others and with the central brain. The arm’s connections to other arms allow rapid communication to function quickly and efficiently.

Researchers are still studying how the octopus puts all this together to move eight arms in a well-coordinated way. Roger Hanlon, a researcher with the Marine Biological Laboratory, said, “We are in that intriguing ‘mild state of confusion’ that is simultaneously perplexing and exhilarating when unexpected discoveries are revealed.”

God’s design of every form of life is amazing and offers much for science to study and learn. Our understanding of how nerves function and how the brain interprets the signals it receives from the nerves is still in a primitive stage. However, we know that each octopus arm moves as if it has its own brain, making the octopus a very complex and intelligent animal. We see God’s wisdom and creative ability displayed in every form of life.

The Heart Is on the Left, but Why?

When I was in high school, a required health course involved a plastic model of the human body with the skin removed and all the organs visible. We named the model “Oscar” and tried to change the arrangement of the organs. We learned that correct internal organ placement is essential, and the heart is on the left.

Getting all the organs into Oscar was difficult because they were hard plastic, and not all organs are symmetrical. We learned that there were reasons for the human body’s design, and the heart is on the left, but we didn’t know why?

We learned there is a reason for the brain to be at the top of the body to avoid a stroke. The pressure in a column of liquid is greater at the bottom than at the top. For that reason, a blood vessel can rupture in our feet but still not be critical to our survival. If our brain were in the lower part of the body, a broken blood vessel would lead to a stroke.

So what determines where our organs are placed? A recent study led by Harvard Medical School researchers gave some answers to that question. In early embryonic development, a cluster of cells called the left-right organizer contains some hair-like structures called motile cilia. They sense the biomechanical forces that shape the body plan. The cilia beat rapidly, moving extracellular fluid in the correct direction to move organs to the proper place to function most efficiently. They are the reason why the heart is on the left side.

Incorrect left-right placement of the internal organs can result in various disorders, including heterotaxy syndrome and primary ciliary dyskinesia. These disorders can cause recurring respiratory infections and congenital heart disease.

In Psalms 139:10-14, David speaks of God’s right hand forming him in the womb. In verse 14, David says, “I will praise you, God, for I am fearfully and wonderfully made…” The more we learn about how our bodies are designed and formed, the more we understand the truth of that statement.

How Cells Dispose of Waste – Autophagy

If you remember your high school biology course, you may recall two organelles within the cell. One is mitochondria, which produce energy for the cell. The other is the endoplasmic reticulum which assembles the proteins to carry out the cell’s job. So naturally, any process as complex as those organelles do will produce some waste byproducts, some of which are toxic. Autophagy is the process of how cells dispose of waste.

In 2016 Dr. Yoshinori Ohsumi was awarded a Nobel Prize for his work in understanding the process. Autophagy degrades some mitochondria and carries out the removal of toxins. The name comes from Greek words that mean “self-eating.” New autophagy research is critical because disease prevention requires efficiently removing toxins from the cell. If autophagy is reduced or impaired, it can start or catalyze the growth of cancerous cells. Scientific understanding of how cells dispose of waste by autophagy may also improve the treatment of other diseases.

The description of autophagy we received in high school biology was greatly simplified, and even scientists today still have much to learn. According to current researchers, “the cell is a complex driver of machinery which is continually being built, put into motion, and eventually broken down.” We know that any machine must be carefully designed and manufactured in a controlled way. That means the living cell is a clear example of the complexity of life.

Creating life required clever engineering and great attention to detail. Autophagy is just one part of what God designed into all living cells. Proverbs 8 personifies “Wisdom” describing her involvement in God’s creative process. That wisdom is apparent in how cells dispose of waste.

Does Naturalistic Evolution Explain Life?

George Gaylord Simpson wrote in his book The Meaning of Evolution (1949), “It is already evident that all the objective phenomena of the history of life can be explained by purely naturalistic…materialistic factors.” In other words, neo-Darwinism explains life. With that in mind, he writes, “Therefore, man is the result of a purposeless and natural process that did not have him in mind.” Despite Simpson’s confidence, does naturalistic evolution explain life?

It is worth noting that Simpson began the paragraph from which I took the above quotes with these words, “Although many details remain to be worked out…” That is an understatement! Those who insist that naturalistic, materialistic evolution explains life completely are purposely overlooking “many details.” Does naturalistic evolution explain life? Here are a few of the problems with that explanation:

The Origin of Life- How did non-living matter become alive?

The Origin of the Genetic Code- DNA contains a massive amount of information, and information originates from intelligent sources.

The Origin of Sexual Reproduction- Most plants and animals reproduce sexually, requiring both male and female gametes. How did this complex process originate and continue?

The Lack of Transitional Fossils– If the evolution of all life has been a gradual process, why don’t we see an abundance of fossils showing transitional stages between life forms? How can you explain the sudden appearance of life forms, such as in the “Cambrian Explosion,” which Darwin admitted was a mystery?

The Development of Complex Organ Systems– How could they happen by gradual changes?

The Development of Irreducibly Complex Molecular Machines– They exist within every living cell and require every part to be in place for them to function. Therefore, explaining their origin through a step-by-step process seems impossible.

Mathematical Difficulties- Mathematicians have calculated that the number of gradual changes required to go from unicellular life to all of the diverse life forms, including humans, would be mathematically impossible within the span of Earth’s 4.5 billion years of existence.

Barriers Between the Types of Life Forms- It is possible with intelligent breeding to produce new varieties of dogs, cows, or roses. However, they are still dogs, cows, or roses. The evidence for one type of living creature evolving into another life form is lacking.

Those are just a few of the details that “remain to be worked out.” Darwin recognized some of them, such as the biological big bang of the Cambrian era and the lack of intermediate fossils. He expected those details would be resolved in the future. More than a century and a half later, there is still no resolution to those problems, and many more have been added to the list.

Does naturalistic evolution explain life? Many scientists accept it because the scientific community would shun them if they didn’t. Others accept it not because of its explanatory power but because they see no acceptable alternative. So when someone says that evolution has disproven the need for God, remind them that these are only a few of the reasons why naturalistic evolution falls short of explaining why we are here.

The Gravitational Constant and Earth’s Mass

“How much does planet Earth weigh?” We can’t put the planet on a scale, and the correct question is, “What is Earth’s Mass?” The scientific literature tells us Earth’s mass is six ronnagrams. That is six followed by 27 zeros (6,000,000,000,000,000,000,000,000,000 g). Newton’s law of gravitation is expressed in the equation F=G(mm’/x²). The m and m’ are the masses of two objects, x is how far they are from each other, and G is the gravitational constant which makes the equation work. The value of G is 6.67430 x 10^-11, that is .0000000000667430.

Any two objects with mass will attract each other. For example, you and the Earth are attracting each other, and you are attracted to the person sitting next to you, such as your spouse or significant other. So why don’t you feel that attraction to each other? (Gravitationally, that is.) If you put your mass and the other person’s mass into that equation, you will find that the force is extremely small. However, if you were in outer space and floating isolated from any other mass, you and that person would be drawn together.

So what is the point? This design of the gravitational constant is an amazing display of God’s wisdom and intelligence. Earth’s mass is so large that you can feel its attraction for you. That prevents you from flying off into space while allowing all of life to have mobility on the planet’s surface. The attraction of gravity on all objects in space pulls them together, with the force depending on the mass of the objects. The matter clumps into meteoroids, asteroids, and comets if the mass is relatively small. Greater mass results in stars and planets, with gravity pulling them into spherical shapes. Gravity also keeps solar systems and galaxies from flying apart. The gravitational constant acting on mass allows the cleansing of debris from space and the continuing production of new astronomical bodies.

The value of the gravitational constant (G) allows the creation of the universe, the Milky Way galaxy, our solar system, and planet Earth. It is just one of many mathematical constants that must be just right to allow matter and life to exist. How did such numbers get chosen? Is this some cosmological accident, or is it the product of intelligence?

Atheists respond by suggesting there are an infinite number of universes with different constants. We just happen to be in the one that got everything right. Unfortunately, there is no way to test this multiverse theory scientifically. It is more like a religious idea that has no purpose except to avoid believing in the existence of an intelligent Creator.

The gravitational constant is only one of many constants that must be fine-tuned for the existence of life in any universe. We have no reason to believe there are other universes, but if there are, they would also have to be created. We believe God created our universe for a purpose. The Bible gives a purpose for human life and states clearly that the creation described in Genesis 1:1 was by a God who created with Wisdom, as we read in Proverbs 8:1, 22 -31.

The Universe Has a Purpose

“In a certain sense, you might say that the universe has a purpose, but I’m not sure what the purpose is. I don’t believe in any religion I’ve seen. So in that sense, I am an atheist.” – Roger Penrose

That statement by the British mathematician, mathematical physicist, philosopher of science, and Nobel Laureate in physics Roger Penrose appeared in an interview in New Scientist magazine. Penrose has won many awards and honors for his brilliant achievements. One of his endeavors has been to explore the origin of consciousness. He believes that the known laws of physics cannot explain the phenomenon of consciousness. The first of his three books on the subject was The Emperor’s New Mind (1989). Since then, he has worked with an anesthesiologist to develop a view of consciousness that he calls “orchestrated objective reduction” (Orch OR).

In the New Scientist interview, Penrose said, “whatever consciousness is, it must be beyond computable physics.” Penrose doesn’t think that consciousness is accidental. He said, “I think the presence of consciousness, if I can put it like that, is not an accident.”

If consciousness is not an accident, then it must be intentional. How can something be intentional without a mind that intends for it to be? How can it have a purpose without a purpose giver? Penrose stated in the interview that “nobody knows where the fundamental constants of nature come from.” He suggests that if those fundamental constants didn’t have the specific values they have, then the chemistry of life could not exist, and we wouldn’t be here. If those constants have the precise values for life, how could that happen without a conscious Designer?

Roger Penrose is a man whom God has gifted with a brilliant mind that, even at age 91, is still pursuing an understanding of the universe and consciousness. He clearly states that he does not believe the universe and consciousness are accidents, but he is seeking to explain them by quantum mechanics. However, he admits, “I would say that there is something going on that might resonate with a religious perspective.”

We agree with Penrose that the universe has a purpose. Purpose in the universe and purpose in consciousness can best be explained by a conscious Mind outside of the universe and beyond the reach of scientific analysis. This is not a “god-of-the-gaps” concept but logically seeking the best explanation. Following through with that understanding means that you, like everyone else, also have a purpose.

The Most Mysterious Number in Physics

Many physical constants determine the structure of the universe. All of them have units or dimensions, such as the speed of light (c) or the gravity constant (G). That is, all of them except one. That one is the fine-structure constant represented by the Greek letter alpha (α). The fine-structure constant seems to be a random number with no units or dimensions, but it keeps showing up in physics calculations. It has been described as the most mysterious number in physics. American theoretical physicist Richard Feynman called it “a magic number that comes to us with no understanding by humans.”

Recognition of the fine-structure constant originated with German theoretical physicist Arnold Sommerfeld in 1916. Chemists can identify different elements in the lab by the spectral lines they emit or absorb when their electrons change energy levels. Astronomers analyze the spectral lines of stars to determine what elements they contain. Some spectral lines are split, showing a fine structure. To explain this, Sommerfeld introduced a new constant into his equations and called it the fine-structure constant. It has no units like the speed of light or other constants. It is just a number – a ratio.

The fine-structure constant shows the strength of the interaction between electrons and photons. It also shows up in many other ratios in physics. The value is approximately 0.007,297,352,569 or 1/137. Physicists consider it mysterious because they don’t know where it came from or why it has that value. They can’t explain why it exists at all. But if you are not a physicist, why should you care about the most mysterious number in physics?

If the fine-structure constant had any other value, life as we know it would not be possible. If you changed that number, you would change the universe. A different value for the fine-structure constant would change the size of atoms and alter chemistry and nuclear reactions. No stable matter, no life, and no intelligent beings would exist. We wouldn’t be here.

Richard Feynman wrote that “all good theoretical physicists put this number up on their wall and worry about it.” Apparently, they worry about where it came from and why it is what it is. Feynman further wrote, “You might say the ‘hand of God’ wrote that number, and ‘we don’t know how He pushed His pencil.”

Feynman was joking about the most mysterious number in physics, but we think it was written by the “hand of God.” We also believe “He pushed His pencil” so that He could create humans for a purpose. More on that tomorrow.

To Accurately Calculate Earth’s Circumference

How was a man living over 2,000 years ago able to accurately calculate Earth’s circumference? How could he even know that Earth is spherical? How can some people today believe that our planet is flat when everyone has seen pictures of Earth taken by satellites in space?

Those may be too many questions at once. Let’s try looking at them one at a time. The first man to accurately calculate Earth’s circumference in about 240 B.C. was a Greek polymath named Eratosthenes. He was a brilliant mathematician, geographer, astronomer, music theorist, and poet, and his calculations were amazingly accurate.

A myth originated from a fiction work by nineteenth-century American author Washington Irving and other authors. Irving wrote a less-than-accurate “biography” of Christopher Columbus. In it, the Spanish authorities questioned Columbus’ plan to sail west to Asia by going east because they thought the ships would drop off the edge of a flat Earth. The truth is that European scholars at that time knew that our planet is a sphere. In fact, Columbus did too, but he believed that it was 25% smaller than it actually is. He should have paid more attention to Eratosthenes.

Ancient Greek scholars, as early as the fifth century B.C., recognized the spherical nature of the planet based on observations. (We have talked about that before.) So Eratosthenes set out to accurately calculate Earth’s circumference. Let’s look at a simplified description of how he did it.

Eratosthenes was the librarian of the famous library of Alexandria in Egypt. Syrene was a city 5,000 stadia south in what is now Aswan, Egypt. (5000 stadia was approximately 800 km or 497 miles.) At noon on the summer solstice, Eratosthenes placed a rod vertically into the ground in Alexandria. At the same time, his assistant had placed a rod of the same length at Syrene. Since Syrene is very close to the Tropic of Cancer, where the Sun is directly overhead at noon on the solstice, the rod did not leave a shadow. In Alexandria, the rod produced a shadow of 7 degrees, which is 1/50 of the circumference of a circle. That means Earth’s circumference would be 50 times the distance from Alexandria to Syrene. Multiplying 50 times 5,000 stadia results in 250,000 stadia for Earth’s circumference. Depending on exactly how long a stadion was, that measurement is accurate to within -2.4% to +0.8%.

That answers the first two questions, but what about people today who believe the Earth is flat when there is plenty of evidence otherwise? That is an example of people believing what they want to believe and refusing to accept the evidence. There is a connection here to the so-called war between science and faith, and it relates to what we read in Romans 1:20. More on that tomorrow.

Elephants and Ecosystems

Yesterday we talked about ecosystems, what they are, and why they are essential. If you looked at yesterday’s picture, you saw that carbon sequestration was among the “services” provided by ecosystems. Today, there is much concern about atmospheric carbon (carbon dioxide and methane) increasing the “greenhouse effect” and causing global warming. That makes capturing carbon an essential service of ecosystems to protect our survival. One vital area involves African elephants and ecosystems.

Elephants are known as megaherbivores because of their size and the fact that they eat plants. New research has shown that elephants have a “profound” effect on forest ecosystems. We have mentioned before that beavers shape their environment to create ecosystems that support many other life forms. Researchers from Sweden, France, and the United States confirm that elephants are also “ecosystem engineers” that “significantly influence the structure and functioning of ecosystems” such as tropical rainforests in Africa.

The positive connection between elephants and ecosystems involves two aspects of elephant behavior. First, African forest elephants prefer to eat the leaves of trees with low wood density. This is because those leaves contain more protein and less fiber than the ones with high wood density. Secondly, elephants prefer to eat fruit from trees with higher wood density. By eating those fruits, the elephants disperse the seeds of the trees that sequester the most carbon.

Elephants spread more seeds of more plant species than any other animal. The elephant’s diet enables the survival and spread of the trees that store more carbon, keeping it out of the atmosphere. At the same time, elephants reduce overcrowding by the lower-density plants, allowing the larger trees to grow. This balance of elephants and ecosystems helps to protect the planet from excess carbon in the atmosphere.

The study concludes that elephant conservation will significantly affect global climate by controlling the amount of atmospheric carbon. God has designed a worldwide system of many ecosystems that make Earth suitable for advanced life to thrive. Our job is to protect the blessings God has given us to enjoy. Who doesn’t enjoy watching elephants?
