Broken Heart Syndrome

The medical name is takotsubo cardiomyopathy, but a more straightforward name is “broken heart syndrome.” Extreme stress or emotions can cause it. That includes the loss of a dear loved one. A “broken heart” can temporarily weaken your physical heart muscle. Research has shown a person has a 41% increase in the risk of dying in the first six months after losing a spouse.

Extreme emotional stress increases the release of the hormones cortisol, adrenaline, and norepinephrine while causing a reduction in the feel-good hormones of oxytocin, dopamine, and serotonin. The result can be broken heart syndrome with depression, poor sleep, fatigue, anxiety, high blood pressure, and physical pain.

I have often heard broken heart syndrome used in connection with Jesus as he agonized in prayer before the crucifixion. After all, while Jesus was fully God, he was also fully man. He was “tempted in all things just as we are” (Hebrews 4:15). But what about the disciples? They had spent three years with Him. He was their closest friend as well as their teacher-rabbi. They had begun to recognize that He was the Messiah who had come to restore God’s kingdom. Imagine the shock they experienced when they saw him crucified like a common criminal. They must have considered the three years they spent with Jesus all for nothing, and their faith in God must have been shaken.

Broken heart syndrome literally changes the structure of your heart, even though we know that the physical organ is not the center of our emotions. So you could say that those disciples were brokenhearted emotionally and physically. They fled and hid and wept and pondered. They were in despair.

However, in a few days, they became bold proclaimers of Christ. They had a new courage that they never had before. They were not afraid of the Roman authorities or the Jewish leaders. There is only one possible explanation. They saw, heard, touched, and even ate with the resurrected Christ.

The disciples were in agony for two days, but on the third day, their broken hearts were restored to “brave hearts.” They never stopped proclaiming Christ’s resurrection, even though their lives were tragically shortened because of their message. There is no way to explain their courage except that they knew first-hand that it was true.

Convergent Evolution or Design?

Animals that are not closely related can display very similar characteristics. Evolutionary scientists say that these similar traits demonstrate “convergent evolution.”

According to Darwinian evolution, all life forms can trace their heritage to a common ancestor. From that first life form, branches diverged to form a tree of life. At some point, those branches diverge again. When two life forms develop a similar characteristic that their last common ancestor did not have, that is convergent evolution. There are many examples, such as dolphins and bats. Both use echolocation for navigating or finding food, but they cannot be closely related.

Animals that can fly include insects, birds, and mammals such as bats. Nobody claims that these creatures are closely related. However, they all use aerodynamic principles and wings to defy gravity. We see similar mouthparts in animals that suck blood, such as mosquitos and fleas. Both are insects but not closely related. We can say the same for insects that suck nectar from flowers, such as bees and butterflies.

Many plants produce edible fruits to encourage animals to scatter their seeds. That includes tomatoes, apples, and raspberries – which are not related. We find similar types of eyes in very dissimilar animals. Birds, butterflies, and even some plants use structural coloration, even though they are unrelated and live in very different ecosystems.

According to evolutionary scientists, one of the most dramatic examples of convergent evolution is found in thousands of plants that use ants to disperse their seeds. The plants attach “food bodies” called elaiosomes to their seeds. The elaiosomes are rich in nutrients to attract ants. The ants carry the seeds to their colonies, where they eat the elaiosomes and discard the seeds. How did over 11,000 plant species develop this technique more than 100 times independently? Evolutionists call it convergent evolution. Could it perhaps be evidence for design in plants?

Evolutionary scientists often give pat answers to explain how various species evolved the same traits independently. However, they say that all of these and many more examples of similarities in unrelated animals show convergent evolution. In other words, evolution is intelligent and uses the same ideas in various species. Or we could say that an intelligent Creator has used the same creative ideas in multiple species. Which is the best explanation? Evidence for design in living things calls for a Designer of life.

Beautiful Insects – Butterflies and Moths

Insects can be beautiful. Today we want to consider a family of insects with about 180,000 described species. They include many of the most beautiful insects on Earth. They are in the Lepidoptera order, and we call them butterflies and moths.

Before they become butterflies and moths, these insects go through a larval stage as caterpillars.

KEYSTONE PLANTS AND CATERPILLARS
WALNUT SPHINX ACCORDION WORM

When the caterpillar has eaten its fill of nutrients from its favorite plant, it goes into a pupal stage and through a complete metamorphosis to become a butterfly or a moth. It is one of the most amazing transformations in nature.

THE INCREDIBLE BEAUTY OF MOTHS
LEARNING ABOUT LEPIDOPTERA
BUTTERFLY WING DESIGN

THINKING LIKE A BUTTERFLY

The English word “metamorphosis” is from a Greek word meaning “transformation.” So the caterpillar goes through a dramatic change in form and lifestyle. That word is used in Matthew 17:2 and Mark 9:2 to describe the “transfiguration” of Jesus Christ on the mountain where He met with Moses and Elijah. Paul used the word in Romans 12:2, where he describes the “renewing of your mind” to live a beautiful life according to the will of God.

There is much more to say about beautiful insects, but we will conclude our review of these fascinating creatures tomorrow.

The Largest Insect Family

Many people fear insects, but those little critters are essential for life on Earth. Although they can be pests, insects perform valuable services, from pollinating the plants that supply our food to removing dead animal carcasses and waste. Yesterday, we looked at mosquitoes and ants. Today we consider the largest insect family – beetles.

We said that even though an estimated 20,000 ant species live almost everywhere on Earth, they are not the largest insect family. Beetle species make up more than one-third of the nearly one million scientifically identified species of insects worldwide. Here are some of the things we have written about beetles.

BEETLES THAT RECYCLE CARCASSES
BEETLES THAT DISPOSE OF ANIMAL WASTE
FIRE CHASING BEETLES
BEETLES THAT WALK UPSIDE DOWN UNDERWATER
JAWBREAKER BEETLES
STINKY BEETLES

Someone said God must love beetles because He made so many of them. Although we might think that beetles such as stink bugs are ugly, many are known for their beauty. However, the most beautiful insects are the ones we will examine tomorrow.

Fear of Insects – Entomophobia

The fear of insects is called entomophobia. It’s a phobia affecting nineteen million Americans, making it one of the top fears people have. The insects people most commonly fear are ants, beetles, grasshoppers, caterpillars, and even moths and butterflies. If I selected the insects I dislike the most, they would probably be mosquitoes – at least the female ones. However, we must realize that insects of all varieties are essential for human life, and even mosquitoes serve a useful purpose.

On this website, we have written about insects many times. Instead of having a fear of insects, we would do well to study and learn from them. The following links to some of the insect articles we have posted can help you see that our six-legged friends are fascinating. Let’s start with those dreaded mosquitoes.

WHY DO WE HAVE MOSQUITOES?
SOLUTIONS TO MOSQUITO PROBLEMS
DANGEROUS ANIMALS THAT WE FEAR

Ants are another family of insects we can’t ignore.

ANTS ARE ESSENTIAL FOR LIFE ON EARTH
ANT ARMOR
ANTS USING TOOLS
ANTS USING VIBRATING SAWS
ANTS USING SEALED DOORWAYS
ANTS OF THE SAHARA DESERT

Ants and mosquitoes live on every continent except Antarctica. Entomologists estimate there are 20,000 species of ants, but only 13,800 have so far been studied and classified. However, ants don’t hold the record for the largest number of insect species. That honor belongs to another insect family, which we will look at tomorrow.

Bacterial Cells in the Human Body

Trillions of bacteria live in the intestines of every person. Perhaps more disturbing is the suggestion that there are ten times as many bacterial cells in the human body as there are human cells. Remember that bacterial cells are smaller than human cells, but still, that’s a lot. Nobody has actually counted them all, but scientists are certain that the bacterial cells outnumber our body cells. Even though that may sound shocking, the truth is we couldn’t live without them. The collection of microbes inside you is called the microbiome, and it makes food digestion possible and plays an essential role in our immune system.

Every time we eat food, we take in bacteria. Your gut biome acts as the first line of defense in a fully-functional immune response. People often refer to “good bacteria” and “bad bacteria.” That distinction may be misleading because the helpful or harmful ways of those microbes may depend on the circumstances.

Gut bacteria work in the breakdown of carbohydrates. Research indicates that obese people have less diversity in their gut bacteria than lean people have. On the other hand, when gut bacteria digest foods such as eggs and beef, they produce a compound that can boost heart-disease risk. Some germs can make you sick, while others keep you healthy. Sometimes the same bacterial cells in the human body can do either, depending on circumstances.

Helicobacter pylori bacteria are known for causing ulcers in the digestive tract. They are present in the microbiome of half the world’s population. Most people don’t have a problem with stomach ulcers, but it is painful and dangerous for the small number who do. However, researchers have found that the absence of Helicobacter bacteria in the gut may lead to diseases of the esophagus, such as reflux and cancers. Other research has shown that Helicobacter species may help the immune system, even though they may lead to inflammation and ulcers.

So the “good” and “bad” distinction between bacteria may be a false dichotomy. Whether they are beneficial or harmful depends. Bacteria considered “bad” might be neutral or even helpful in certain situations. A person’s health status, stress, diet, and genetics all influence how we react to various bacterial cells in the human body.

Another beneficial use of bacteria could come from research into using them as a medical delivery system to regulate autoimmune diseases. There is a clear answer for those who consider bacteria as all bad and question why God would create them. As science continues to explore the complexity of the system of life, we see God’s wisdom in all of creation.

Listening for Messages from Space

In 1960 radio astronomer Frank Drake began research to find alien civilizations in deep space by aiming an 85-foot radio telescope at some sun-like stars. He found nothing, but it was the beginning of a program known as SETI – Search for Extraterrestrial Intelligence. The program has continued for 63 years, with many radio telescopes listening for messages from space. Researchers have spent thousands of hours and millions of dollars with zero results. They have detected no deep-space radio signals containing any intelligence – only noise.

Radio signals continuously originate from stars, nebula, and other space objects, but it is all noise. How do the SETI scientists know it’s just noise and not intelligence? Intelligence has a pattern. They may not understand the language, but they can tell language from random noise. They can distinguish random, accidental, chance blips from something created by an intelligent being.

Thus, scientists have confidence that they know the difference between information transmitted by an intelligent being and random noise when listening for messages from space. How about when examining the DNA within living cells? Does the complex pattern of information that creates the blueprint within each living cell show intelligence behind it – or is it random noise? Does it resemble a computer program written by a super-intelligence, or does it display random, accidental chance? If we can tell the difference between intelligence and randomness in space, why can’t we tell the difference in our own bodies? Is the problem that some people want to find signs of intelligence in deep space but don’t want to see it within our cells?

Frank Drake admitted that in 1974 he transmitted an encoded message toward a star cluster 25,000 light-years away in the constellation Hercules. That means the message should reach its target in 25,000 years (minus 49 years). If any intelligent being gets the message and responds immediately, the return message will take 25,000 years. Unfortunately, Drake died in 2022, at age 92, without getting a message back.

Is it possible that there really is an intelligent Being out there listening and waiting to hear from us? Is it possible that Being is not limited by time and space? Is it possible that the Being has already communicated with us by coming to Earth and taking on human form? Is it possible that while spending time and money listening for messages from space, we are not listening to Him?

We have dealt with SETI before, as you will find HERE, HERE, HERE, and HERE.

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.

Sleep as a Great Time Waster

As a teenager, it was frustrating that I was supposed to spend a third of my time asleep. I thought of sleep as a great time waster when there were so many things I wanted to do. I thought I could accomplish much more by staying awake.

The truth is that humans need sleep, and so do all animals. Birds, fish, and even insects need periods of dormancy to survive. Even plants need “sleep.” Sunlight empowers photosynthesis in plants to produce the nutrients they need for survival and growth. Therefore, it seems that plants should grow faster if they had sunlight 24 hours a day. Not so. If you set up an indoor garden with artificial lights, you will find that the plants need dark periods. You can even change the “seasons” for the plants by varying the percentage of darkness and light.

Instead of seeing sleep as a great time waster, we know that it is a vital biological process essential for the survival and well-being of living things. Sleep is necessary to maintain good health by restoring and repairing the body’s tissues and organs. During sleep, the body produces hormones that help repair damaged tissues and build new ones. Sleep plays a critical role in the immune system, as it helps the body produce cytokines, a type of protein required to fight infection and inflammation.

Sleep is also crucial for the regulation of metabolic processes. Working with our circadian rhythm, sleep helps to regulate appetite and energy balance. Sleep deprivation can lead to increased hunger and decreased production of hormones that regulate appetite, such as leptin and ghrelin. This can lead to weight gain and obesity, increasing the risk of developing several chronic health conditions.

Sleep is essential for more than just physical well-being. During sleep, our brain processes and consolidates memories and data acquired during awake times. The lack of sleep can impair attention, memory, decision-making, and emotions. Sleep aids in the consolidation of learning and the formation of new memories. During sleep, the brain replays and consolidates memories from the previous day, helping to strengthen and make them more resistant to forgetting.

Now that I am old, I appreciate sleep much more than I did as a teenager. I no longer see sleep as a great time waster but as a blessing from God. I have found that some of my best ideas come to me at night. I can wake up with a new idea or a fresh way of looking at things. Sleep has cleared away the fog in my mind so I can see things I had overlooked.

I am also thankful that God doesn’t sleep. We can sleep because He is our protector 24/7/365. Psalms 121:3b-4 says, “He who keeps you will not slumber. Behold, He who keeps Israel shall neither slumber nor sleep.” So when our melatonin level increases and our circadian clock tells us it’s time to sleep, we can rest knowing that God is still at work keeping the world going. “The Lord’s love never ends; his mercies never stop. They are new every morning” (Lamentations 3:22-23 NCV).

When Obeying God Doesn’t Make Sense

God’s first command to Adam and Eve did not seem to make sense. God created many beautiful trees, but one of them was different. God told the first couple they could eat the fruit from any of the trees, with only one exception. They must have thought that obeying God doesn’t make sense. Why should one tree be off-limits?

Sometimes we must tell our children to avoid doing something that doesn’t make sense to them. To a small child, we say, “Stay out of the street.” They look at that open space where they could run or ride a tricycle. It seems like a fun place to venture into. Genesis 3:6 says that Eve saw the forbidden tree was “good for food” and “pleasant to the eyes.” How could it be possible that God was right when He said that eating from that tree would lead to death (Genesis 2:17)?

Eve knew what God had told Adam about the tree. In Genesis 3:2, she goes even further when she says that even touching it would lead to death. Was she embellishing what God had said, or had she received further warnings? Did she know that if she touched it, she would want to eat it, just like the child who is near the street wants to step into it? Like that child, did the woman even understand what death is?

God couldn’t explain to Adam and Eve why He put that tree in the garden any more than the road builders could explain to the young child why they put the street in front of his house. The “why” didn’t really matter. The point is that just as the parent who tells a child to stay out of the street is wiser than the child, so God was wiser than the newly-created couple. Just as the child must learn to obey, so did Adam and Eve.

Learning to obey wise warnings is more important than knowing the reason. When we demand an explanation, we are saying that we are our own masters and will decide what we will do. Doing what God commands even when obeying God doesn’t make sense means that we believe He knows more than we do. It means we trust God, even though our desires and our culture tell us to take a different action. We must overcome our feelings and pride to obey, even when we want to run out into that street.

Jesus said, “If you love me, you will keep my commandments (John 14:15). When Jesus says to love your enemies, turn the other cheek, go the extra mile, and pray for your persecutors, we think, “Obeying God doesn’t make sense.” (See Matthew 5:38-48.) Like the child running into the street or Eve reaching for the forbidden fruit, we want to rebel and trust our own understanding. But we need to remember the words of Jesus in John 15:10-11, “If you keep My commandments, you will abide in My love, just as I have kept My Father’s commandments and abide in His love. These things I have spoken to you, that My joy may remain in you, and that your joy may be full.”
