Benefits and Challenges of Squirrels

Benefits and Challenges of Squirrels

We find it interesting to consider the benefits and challenges of squirrels. Now that most of our trees in this area have shed their leaves, we can see nests that are different from bird nests high in our trees. They are round and are not open on the top. The nest design programmed into the squirrel DNA has the structural integrity to withstand high winds, heavy rain or snow, and even the invasion of most predators.

Squirrels begin by weaving twigs to make a floor or platform for the nest, usually in a fork high in the tree. Next, they place damp leaves or moss on this floor and weave it around the base, making a spherical nest. Then they stuff leaves and twigs into the sphere, leaving an inner cavity which they line with shredded bark and leaves. Squirrels usually complete their construction in the fall, although they may start as early as June. They are typically solitary but may share a nest for warmth in the coldest winter months or for mating and raising their babies.

Squirrels may also take advantage of any shelter they can find. For example, they can use an old woodpecker nest in a hollow tree and line it with moss and leaves. Unfortunately, squirrels will also take advantage of human structures to nest. For example, they may exploit an abandoned car, a hole in a roof, a woodpile, or an unused boat or camper. Being aware of the abilities of squirrels gives us a way to avoid damage or problems they might cause.

Squirrels are intelligent and very athletic animals. Those of us who have bird feeders can tell many stories of how squirrels evaded our best efforts to keep them from eating the birdseed. The main diet of squirrels is nuts and seeds, but they also eat insects, grubs, and beetles. They frequently bury nuts for later use and fail to dig up a percentage of them which then grow into trees. Oak trees planted by squirrels are a significant part of reforestation in northern areas.

As we think about the benefits and challenges of squirrels, remember that they are wild animals that can spread disease and insect bites from fleas, chiggers, and tics. Despite the challenges squirrels present, these small animals are designed to give us more benefits than problems. Enjoy the creatures God has given us to serve a purpose on this planet.

Life Issues from Beginning to End

Life Issues from Beginning to End

The media have recently reported on several life issues from beginning to end. Here are some examples:

The German Euthanasia Association has announced that those seeking euthanasia must produce proof of COVID vaccination
to legally end their lives. This is apparently to protect healthcare workers.

In Poland, the government has passed a law requiring doctors to report all pregnancies and miscarriages to a government database. The apparent reason for this is to make sure that all pregnancies end with a birth. Unfortunately, Poland has a shortage of workers, and this seems to be the government’s solution to the issue.

Research has shown that women who use marijuana during pregnancy are more than twice as likely to have aggressive, hyperactive children with heart rate and immunity issues.

Babies have a fragrance that comes from an organic compound called hexadecanal. It is found in human skin but is abundant in a baby’s scalp. Research shows that females exposed to the fragrance become more aggressive and strong defenders of their babies. On the other hand, men exposed to it become more gentle and speak with softer voices. Evolutionists claim that this is an evolutionary survival mechanism. We would suggest this is part of God’s design of the human reproductive system.

Research on adopted children shows that some traits are common to adopted children that do not commonly appear in children who are not adopted. In the nine months of pregnancy, there is a “primal bonding that happens by biological design.” Those of us with adopted children can attest to some behavior issues that may be related to the adoption process.

God gave us the ideal arrangement for family–one man and one woman in love with each other produce children they love and care for. Unfortunately, that arrangement is not always possible. Understanding the stress and feelings involved can go a long way toward making adoption a good experience.

As we examine life issues from beginning to end, we know that every child needs a loving family, and every senior adult needs someone who loves them.

Why Zebras Wear Stripes

Why Zebras Wear Stripes

A child said that a zebra is a horse in striped pajamas. Of course, zebras are not horses, and they don’t wear pajamas. But have you ever wondered why zebras wear stripes? And I have another question—are they white animals with black stripes or black animals with white stripes?

There are at least five possible answers to why zebras wear stripes. Probably the best known is so they can hide in the tall grass. But not all zebras live in areas with tall grass. Also, their main predators (lions and hyenas) are not good at seeing far away. They are more likely to smell zebras before they see them.

Another possibility is that the stripes help to repel flies. In a study published in 2020, researchers put rugs on horses to test that theory. They draped solid-color rugs on some horses and striped or checked rugs on others. They found that fewer flies landed on the horses with striped or checked rugs, and those biting African horseflies carry diseases that can be fatal for zebras.

Still, another idea is that stripes help zebras stay cool. The black and white areas create differences in heat exchange patterns causing air to move over the zebra’s body. So we think the stripes make the zebras look “cool” too.

Every zebra has a different stripe pattern, like how every person has a different fingerprint. So maybe this allows the zebras to identify each other. We don’t have to look at people’s fingers to tell who they are. Instead, we look at their faces. However, zebra faces look pretty much the same except for those different stripe patterns.

Maybe those stripes work in another way to evade predators. Perhaps they fool predators by what is called “motion dazzle.” A bunch of striped zebras moving around might confuse a predator in the way a person can become confused or dizzy watching striped objects in motion. So it makes sense that it would be hard to pick out one animal in a herd of moving zebras.

So if we wonder why zebras wear stripes, the answer is–we don’t know for sure. As far as the other question, zebras have black skin, and their default hair color is black. However, some hair follicles have turned off the melanocytes that produce the melanin that gives the hair its color. So those hairs are white. So, therefore, you could say that zebras are black with white stripes.

But that brings up the question of why are those melanin-free hair follicles so nicely arranged in beautiful stripes instead of randomly, resulting in a dull gray appearance. People appreciate beauty, and since we are created in God’s image, He must also be a fan of beauty. I want to suggest that God just likes to add a little extra flair to His creations. He has certainly created many beautiful things, and zebras are just one of many examples. Perhaps that’s why zebras wear stripes.

Seeing Is Not Always Proof of Reality

Seeing Is Not Always Proof of Reality

If you see a picture of it, it must be real – right? The answer is absolutely not. Human gullibility is astounding, and fake pictures are as old as photography. In 1839, Hippolyte Bayard convinced people that he had committed suicide by creating a photo showing himself as a drowned man. In fact, Bayard lived until 1887. Seeing is not always proof of reality.

In the early 1900s, there were many faked pictures using double exposures, cropping and rephotographing, or even using models. One of the most famous pictures was the “Loch Ness Monster.” The photo got worldwide distribution in 1934. However, in 1975, the son of one of the pranksters admitted that it was a picture of a toy floating in the water.

In our day of technological altering of photographs, anyone can doctor a picture to appear authentic. This is especially true when there is a lot of media hype about a monster, an alien, or a ghost. Reflections from a window have confused many people, even pilots who mistook what they saw as a UFO. Unfortunately, seeing is not always proof of reality.

Many years ago, I helped my wife on a hike with a bunch of young girls
. We stayed too long in the woods and were walking back in the dark. An object that looked like a ghost appeared in front of us. It had two eyes, a round mouth, and a narrow nose. It had an odd green glow, and it didn’t move, but the girls started screaming and crying. When I turned my flashlight on it, we could see that we were looking at a hollow, dead tree with holes in locations that made it look like a face. It was glowing because of the northern lights. Around Lake Superior, there are veins of glowing minerals, and ghost stories have arisen when people saw that effect and didn’t know what it was.

Another personal ghost story involves a haunted house in Scotland where we were invited to spend the night (for a fee). We were told to expect haunting ghost sounds, including moans and screams and footsteps on the stone floor above us. The windows in the house were very old, and, given enough time, glass flows. Unfortunately, the glass had flowed to the point that there were holes in the windows. When the wind blew through the holes, it made sounds. The house cooled rapidly in the evening, and as the stones in the floor contracted, they made sounds that resembled footsteps.

Seeing is not always proof of reality. There is no credible evidence of ghosts, aliens, monsters, demons, or zombies roaming around. We do not live in a world full of non-human spirits trying to harm us. People often resort to ghost-like explanations when they see something they don’t understand. When Jesus walked on the water (Mark 6:49), the immediate response of His disciples was to cry out that they had seen a spirit. Jesus told them not to be afraid, and He would say the same to us.

Life After Death – A Concept Common to Humans

Life After Death – A Concept Common to Humans

Humans from the earliest times have believed in life after death. One of the unique human properties is that we alone believe in a continued existence when our physical life has ended. Most animals simply abandon a dead member of their species. There has been some attempt to claim that elephants, whales, and apes exhibit mourning and stay with the body of a deceased member of their group. However, many researchers agree that interpreting their actions as mourning is not justified. Humans tend to view animal behavior in our image, a process known as anthropomorphism.

As science discovers more fossils of ancient humans, the pattern of preparing a deceased member of the group for another existence becomes apparent. Anthropologists are interested in a South African cave system burial site. There they have found 28 skull fragments and six teeth of what appears to be a child with human characteristics 35 feet (10.6 m) below ground. The bones do not seem to have been washed into the cave or dragged in by scavengers or predators. Researchers gave the specimen the scientific identity of Homo naledi.

Lee Berger of the University of Witwatersrand in Johannesburg reports that this fossil shows strong evidence of a “ritualized body disposal” of the specimen, which they nicknamed “Leti.” Ancient burial sites have almost always indicated that others prepared the deceased for life after death. Sometimes the body is mummified, and sometimes jewelry or weapons are left with the body. There are even cases where an animal or mate was buried with the deceased.

There is a scant reference to life after death in the Old Testament. In 2 Samuel 12:23, David expressed faith that he would see his deceased baby in the future. Job said that after his body had been destroyed, he knew he would see God (Job 19:25-27). Daniel saw a “man clothed in linen” who told him he would “rest” and then “at the end of the days” he would rise and “receive his allotted inheritance” (Daniel 12:13).

The New Testament is full of references to life after death, especially in the teachings of Jesus Christ. The war between good and evil is rooted in the understanding that death is a product of this physical world and Christ has conquered it. (See 2 Timothy 1:10; Revelation 20:14 and 21:4.)

Human spiritual nature is unique because God created us in His image. Our soul allows us to think beyond this life and anticipate an eternal, time-independent relationship with God. That concept has been present in humans from the very beginning and is still present today. Our spiritual nature allows us to express ourselves in art, music, and worship. It also gives us the hope of eternal life in an existence beyond anything this world has to offer.

Elephant Trunks as a Model for Robots

Elephant Trunks as a Model for Robots

New research shows that using elephant trunks as a model for robots, engineer-designers may soon create machines capable of doing things that no current robot can do. For example, the elephant trunk has 40,000 muscles that work together to allow the animal to pick up a single leaf or lift and move a large log easily.

Researchers used motion capture technology similar to that used to create movies where the movement of animated characters is mapped to the motions of real actors in a studio. Studying elephant trunk movements by this method allowed the researchers to carefully examine the myriad ways an elephant uses its trunk.

The elephant’s trunk has an infinite number of degrees of freedom. We can see a similar property in a limited way in the human tongue. Like the elephant’s trunk, our tongues have no bones, and some of us can curl, twist, and contort them in various ways. The ability to speak requires complex tongue movements.

Using elephant trunks as a model for robots is a real challenge to engineers. Designing a robotic arm with complex movements and strength is an important goal. Looking at the elephant’s trunk design, it does not seem possible that this could be a product of chance. Yet, the elephant’s survival is only possible because of this highly complex appendage.

Some animals have tongues that can do interesting things, but the elephant trunk is unique. By using elephant trunks as a model for robots, we can gain some essential insight into making a robot that can do the things we can do with our hands. It becomes clear that all of nature shows God’s handiwork and teaches us important lessons.

Egg Shape and the “Egg-quation”

Egg Shape and the “Egg-quation”

When you look at the eggs of different birds, you will notice that they have different shapes. Some are round like the eggs of most owls, and some are elliptical like the eggs of an emu. Others are oval, such as chicken eggs, or pear-shaped like the eggs of a penguin. Why is egg shape important? There has been a need to know how to pack eggs to support them to prevent cracking. This is not just important for people who raise chickens and sell eggs at your local grocery store but also for conservationists protecting birds in the wild.

This need to understand egg shapes led to studies by scientists at Kent University in England. They came up with a mathematical formula with four essential inputs: 1-egg length, 2-maximum breadth, 3-diameter where the pointed end terminates, and 4-location of the egg’s maximum diameter in relation to the midpoint of its length. The problem was that the earlier mathematical analysis didn’t work on pear-shaped eggs, but the formula works for any egg shape by adding the fourth variable.

This is a classic example of two things. One is that research that may seem pointless to a casual observer frequently provides needed information. So, for example, people wanting to transport eggs, incubate eggs efficiently, and restore bird populations in areas where they have become extinct will use this equation.

A second thing this research shows is the incredible design of the egg. An engineering equation allows the design of precise egg shape construction to fit all environments. This is a complex engineering problem with practical applications, and it shows that even the ordinary egg speaks of the Creator’s wisdom and skill in providing for His creatures.

Study Challenges a Basic Assumption of Neo-Darwinism

New Study Challenges a Basic Assumption of Neo-Darwinism- White-footed mouse
White-footed mouse (Peromyscus leucopus)

A long-term study of 27,224 mice over 26 years challenges a basic assumption of Neo-Darwinism. The assumption is that natural selection guides evolution by removing “unfit” individuals. Therefore individuals that are more fit survive to pass on their genes. The study involved white-footed mice (Peromyscus leucopus) in the wild.

Researchers identified mice with broken, missing, or deformed limbs, missing eyes, cataracts, and missing or mutilated tails. Evolution predicts that these unfit mice would be removed from a population, and the researchers set out to see how quickly that would happen. The data shows that the survival rate of the impaired mice was no different from that of mice who had no physical impairments.

For humans, this observation would be even more dramatic. That is because humans crippled for many years have lived long lives, supported by family members or group associates. That kind of support has never been observed in mice. Moreover, human history is full of terrible acts by racists and political leaders, such as Hitler, who viewed minor physical characteristics as justification for persecution and even execution of other humans.

The evidence is that physical impairments in the animal kingdom do not necessarily cause the demise of an individual. This challenges a basic assumption of Neo-Darwinism which, like uniformitarianism, is not supported by the evidence.

Drug Safe-Havens Don’t Work

Drug Safe-Havens Don't Work

On December 1, 2021, the United States joined Canada, Australia, and Europe in allowing drug safe-havens for people who wish to use heroin and other narcotics. Mayor Bill de Blasio of New York City announced that having monitored facilities where someone watches for overdoses will save lives. The first facility in New York was set to open immediately.

Federal laws ban operating a place for narcotic use, but those laws have been poorly enforced. It is interesting that there is no evidence that these facilities provide help for those who are addicted. There have been negative results in other places where governments have tried legalization. Other moral issues such as prostitution and sexual abuse become part of the scene.

Setting up drug safe-havens, making it easier for people to use narcotics, is sanctioning people to harm themselves. Even though they may not die immediately from drug usage, the long-term result is not good. Should the government provide a way for people to become addicted? The news releases on the New York City plan do not say that drugs will be provided. If that is true, drug dealing and the problem of contaminated drugs will continue.

Licensing sin has never worked, and neither will drug safe-havens. Instead, the legalization of gambling has increased crime, prostitution, economic damage, and family breakdown. As the world turns away from God and denigrates the teachings of Jesus, we are not surprised that politicians will seek to condone the sin industries and tax them.

In 1 Thessalonians 5:21-22, Paul admonishes Christians to “Bring everything to the test and cling to that which is good and rejecting all that has a look of evil about it.” Therefore, let us oppose the movement of our nation toward embracing the sin industry as it offers an alternative to the teachings of Jesus Christ.

Mother Birds Sing to their Eggs

Mother Birds Sing to their Eggs

Recent studies have shown that mother birds sing to their eggs while incubating them. Researchers found that bird embryos learn to identify the sounds of their species before they hatch from the eggs. They also found that the singing is deliberate and serves a purpose.

The reason mother birds sing to their eggs can’t be for their survival, because singing puts the mothers at risk from predators. Then what is the advantage of the singing? In addition to learning the songs of their species, the young birds learn to recognize unfamiliar songs produced by other bird species. The mother’s singing also affects the heart rate of the unhatched bird. All of the eggs in the study of unhatched baby birds showed a decrease in the babies’ heart rate when their mothers sang to them.

Previous research has shown that the heart rate of unborn humans also slows when the mother is in a stable situation and increases when the mother is under stress. Similarly, the researchers speculate that the singing of the mother bird aids the survival of the chick. The research co-author said, “Birds are like humans in that there is a mother- or father-offspring communication even before birth.”

The message is clear that the individual begins life and learning before being put into the world of self-preservation and survival. Mother birds sing to their eggs, and human mothers sing and talk to their babies before birth. In both cases, the offspring benefit. Whether a bird or a human, individual existence begins when life begins–not when the egg hatches or the baby is born.
