One of the most remarkable birds on the planet is the ptarmigan. Along with the snowshoe hare and the Arctic fox, the ptarmigan is a master of disguise. What these animals do is change from dark colors in the summer to totally white in the winter. When I was in Alaska, I saw these animals in the snow. Their coloration was as white as the snow itself, and the only thing you could see was a pair of eyes.

What is unique about the ptarmigan is that they seem to be aware of the importance of their coloration. The changeover from winter plumage to summer is a difficult time for a bird because of the danger of predation if they lose their camouflage. However, if they dropped all of their feathers, they would be unable to fly. What the ptarmigan does is seek out patches of mud and dirt and bathe itself so that its camouflage remains effective.

The question is how the ptarmigan knows to do this. With a brain the size of a pea, this bird could not reason and plan this camouflage behavior. The three species of ptarmigan (rock, willow, and white-tailed) were designed to be aware of their environment and themselves. Joe Jackson wrote in Alaska magazine, “This is a bird that’s hyperaware of what’s around it, and, we now know, hyperaware of itself.”

Trying to explain this astonishing behavior by chance is creative but not logical.  It appears that an intelligence has designed a system that enables this bird to survive in a complex environment. We truly can “know there is a God through the things He has made” (Romans 1:20).

Sperm Cell Design for Reproduction

Sperm Cell Design for Reproduction

With the number of children born every day on planet Earth, it is easy to miss the complexities of human reproduction. All animal life on our planet radiates this complexity, and the sperm cell is the most complex of all the cells in the body. Science is still struggling to understand sperm cell design, but we are learning more about how it functions as technology opens doors that were previously unavailable.

The sperm cell has three parts: (1) The head, which contains a haploid nucleus carrying half the normal number of chromosomes. It also has an acrosome, which contains enzymes that enable it to penetrate the egg. (2) The middle, which is packed with mitochondria to provide energy for the sperm’s movement. (3) The tail (Flagellum), which allows the sperm to swim through the female reproductive system.

Sperm cells are also biconcave or disk-shaped, allowing them to absorb oxygen more quickly and rounded to flow easily through the tiny capillaries. Sperm cells can swim fast thanks to a tail, a streamlined shape, and a high concentration of energy-transferring mitochondria.

The sperm cell design is just half the story. The egg becomes concave at one spot, allowing a single sperm cell to complete fertilization. All animal life depends on this design. The mechanism by which this happens is not understood and is the subject of modern research. We take for granted the fact that animal life can reproduce, but the design that makes it possible speaks eloquently about the existence of God.

 A Partial Solution for Invasive Species

 A Partial Solution for Invasive Species - Nutria
Nutria Pair

The California Department of Fish and Wildlife (CDFW) has suggested a partial solution for invasive species: eat ‘em. Erin Huggins of the CDFW wrote, “Eating invasive species can help protect native wildlife by reducing their numbers and limiting the damage they cause to ecosystems.”

The nutria is an invasive species causing problems in 18 states, particularly in California. These rodents are native to South America but were initially introduced into the United States for the fur trade. Officials thought they had eradicated them from California in the 1970s, but they began to reappear in 2017. Nutrias cause significant problems for farmers and livestock owners, as they eat vegetation right down to the root. Nutrias are even more omnivorous than goats, so they are more destructive.

This is not the first time an invasive species has become an issue. In the 1970s, Asian Carp were introduced into ponds to control the growth of aquatic plants. Four East Asian species were introduced: silver carp, bighead carp, grass carp, and black carp. Some of these species would jump high out of the water when disturbed, creating a hazard for recreational boaters, and elaborate measures have been taken to keep them out of the Great Lakes.

Fish and wildlife officials are now advancing a partial solution for invasive species — making them a food source for humans. Even high-end restaurants now offer nutria and carp meat on their menu. Selling the public on this will take time. Consider that there was a time when Europeans shunned tomatoes, considering them to be poisonous.

The Bible has a good record of banning meat that would be hazardous for human consumption. A familiar prohibition of the Old Testament was against the eating of pork (Deuteronomy 14:8). The Israelites were also told not to eat anything that had already died or any bird or fish that could have eaten contaminated meat, such as vultures, owls, and falcons.

Strong evidence for the inspiration of the Bible is its accuracy in giving the ancient Israelites health guidelines that were far ahead of their time. We rely on science today to provide us with guidelines for healthy eating. A partial solution for invasive species might be to eat them, but a better solution is for humans to avoid upsetting the natural balance in God’s well-designed world.

Bogong Moths and Stellar Migration

Bogong Moths and Stellar Migration
Bogong Moth (Agrotis infusa)

Since ancient times, humans have used the stars for navigation. So have various animals and migratory birds. Even some insects use the stars to guide their flights at night. For the first time, researchers have discovered that insects use the stars to guide their long-distance migrations. The insects are Bogong moths, native to Australia.

Researchers spent years studying the migration of Bogong moths. They wanted to know how a moth flying at night could journey 620 miles (1000 km) to a place it had never been before. After spending their summer in the cool, dark caves of the Australian Alps, every autumn, they travel to their breeding grounds in the Australian bush.

Since Bogong moths travel at night, they can’t navigate by the Sun. Past research has shown that birds, as well as some insects such as dung beetles, use Earth’s magnetic field to guide their flight. However, dung beetles travel only a few meters, not 1000 kilometers. Researchers sought to understand how Bogong moths navigate their way.

Researchers captured some Bogong moths and placed them in a planetarium-like flight simulator that blocked Earth’s magnetic field, allowing the moths to navigate by eyesight alone. The research concludes that the moths use the stars to guide them.

These moths aestivate (remain dormant) during the hot summer, huddling tightly together on cave walls or dark crevices, and migrate in the cooler weather to eat and reproduce.  What is the purpose of these moths and their stellar migration? They nourish various predators in Australia. Many birds rely on them for food. Additionally, mammals, particularly pygmy possums, depend on them. Even Australian aborigines have feasted on Bogong moths.

We have described long migrations by butterflies, including monarchs and painted ladies. However, butterflies are active during the day, but moths fly at night. Bogong moths are the first insects known to migrate long distances at night using the stars for guidance. Is the remarkable migration of the Bogong moths merely an accident, or is it another essential part of an incredibly complex, designed system of life?

Collateral Damage of Cohabitation

Collateral Damage of Cohabitation

If you listen to today’s music, whether country, heavy metal, folk, or pop, you will hear that “hooking up” is the thing to do. Television shows and movies add to the commercialization of sex, so we see the collateral damage of cohabitation in the entire entertainment industry.

Roughly 20.1 million couples in the United States live with an unmarried partner. That is approximately 8% of U.S. couples, most of whom are in the 25- to 34-year-old age group. According to Pew Research, by double digits, married adults are more likely to trust their spouse or partner to be faithful to them, to act in their best interest, to always tell them the truth, and to handle money responsibly. That means those who are cohabiting may never experience the complete joy and commitment that God intended for the marriage relationship.

Not only do the participants in cohabitation not know the security or commitment that comes from God’s design for marriage, but they also lose the structure of the nuclear family as God intended. Children grow up living with constant change in their home situation. Those of us who have been foster parents or have adopted children know how hard that is for the kids.

The collateral damage of cohabitation is a worldwide tragedy, with drugs, including alcohol and marijuana, catalyzing the instability of these relationships. Every culture in which marriage and family disintegrate is doomed to collapse. Will America learn from history or repeat it?

Animal Pathogen Transmission to Humans

Animal Pathogen Transmission to Humans - Bird Flu

The World Organization for Animal Health and the World Health Organization released data on the number of illnesses and deaths caused by pathogens transmitted to humans from animals worldwide each year. They gathered data from 183 member states, showing that a billion illnesses and millions of deaths occur worldwide due to animal pathogen transmission to humans.

The recent data was triggered by the outbreak of bird flu known as H5N1. That virus has sickened millions of birds, dozens of mammalian species, and people worldwide. This strain of avian influenza has threatened food supplies and pressured governments to take a serious look at food security and public health.

When God created life on Earth, He planned it to meet the needs of humans. Long before modern science, God gave dietary instructions to the ancient Israelites. Skeptics today may consider those instructions archaic; however, they were far ahead of their time, and many of them remain applicable today. We see the consequences of not following wise dietary and health instructions.

Animal pathogen transmission to humans is not the only problem we face today. Every time humans have discarded the Bible as a guide for life, the consequences have been dire. We are seeing that again in the tragedies of humans suffering because of the rejection of God’s design for healthful and moral living.

Dealing With Disasters

Dealing With Disasters

One of the challenges that we all face is dealing with disasters such as tornadoes, hurricanes, and floods. Skeptics claim that if a God exists, He wouldn’t allow these terrible natural disasters to take place. That claim displays a combination of scientific and theological ignorance.

Tornadoes result when hot air is trapped under a layer of cold air. Warm air rises, but if the cold air above it is dense enough, the warm surface air will become even warmer. Eventually, the hot air will rise through the cold layer. Hang glider pilots and soaring birds look for these vertical updrafts. When the ground is covered with vegetation, there is never enough heat to trigger a strong upward air movement. However, when thousands of acres of land are plowed up or paved over, the surface air becomes hotter and creates stronger vertical movement. Earth’s rotation spins these upward air movements, creating a tornado.

Areas around 30 degrees north and south latitude are usually deserts. The states of Florida, Georgia, Mississippi, and Alabama are at or near 30 degrees north latitude. Hurricanes pick up massive amounts of water from the ocean and dump it on the land. Without hurricanes, there would be a water shortage in many places. In the past, storm surges were not a problem because the coastal areas were lined with mangroves and other plants on the barrier islands and along the mainland coast. Today, that protection has been stripped away and replaced with hotels, roads, parking lots, and beach-front homes. The result is that we are dealing with disasters.

God told humans to take care of the Earth, but greed, selfishness, and ignorance have often caused disasters. The more we learn about the creation, the more we understand that God designed it to work well, but humans have brought much pain and suffering on ourselves by misusing God’s gift. We must work together and avoid repeating past mistakes, or we will continually be dealing with disasters.

The Value of Fathers

The Value of Fathers

Father’s Day brings to mind the value of fathers. Scientific research recently verified something that should not have been a surprise. The study involved scholars from the University of Virginia, Hampton University, and others. The conclusion was that children who have “actively involved fathers” do significantly better academically, emotionally, and behaviorally.

What is an actively engaged father? According to the study, those fathers manage parenting obligations “very well” and regularly share meals with their families at least four times a week. The study found no difference between fathers of different races. It is not the skin color that matters, but rather how actively the father is involved with his children. The educational level also did not affect the value of fathers.

What difference does marriage make? The study revealed that 51% of children with married parents had fathers who were highly engaged. That was the case in only 15% of children who had cohabiting parents.

What is the value of fathers who are actively engaged? The difference they make is in three areas: grades, behavior, and depression. Girls with fathers who are involved in their lives were 8% more likely to have better grades and only one-tenth as likely to be diagnosed with depression. In other words, a supportive father has a profound effect on a girl’s emotional well-being.

For boys, the value of fathers relates more closely to behavioral support. Boys with engaged fathers were 13% less likely to have behavioral issues in school compared to those with non-engaged fathers.

This study analyzed data on children in Virginia; however, the same findings are likely to hold true in other states and even different countries. The family is God’s design, and the greatest success in life results when a married father and mother are wholly committed to each other and work together to support their children. (See Ephesians 6:4.)

Fruit Flies and Humans

Fruit Flies and Humans

The genetic data contained in DNA is rich in information. The DNA in living cells contains molecular genes that direct the synthesis of proteins necessary for the development of an organism’s body during embryonic development . As we mentioned in a previous post, the DNA of a fruit fly is 60% similar to that of a human. How can we explain the significant difference between fruit flies and humans?

How can similarities exist in the DNA of organisms that look and function very differently? According to Stephen C. Meyer, “scientists have found that the larger informational context in which genes are expressed often determines the specific function of the proteins they produce.” For example, Meyer notes that a corresponding gene in insects and vertebrates regulates the production of appendages. However, in fruit flies, it regulates the development of compound limbs with exoskeletons and multiple joints. In sea urchins, it regulates the development of spines. In vertebrates, it regulates the development of limbs with internal bony skeletons and multiple joints.

Orthodox evolutionary theory suggests that since genes control the development of anatomical structures, the corresponding genes should produce corresponding structures in various organisms. That would eliminate the differences between fruit flies and humans. Clearly, genes perform different functions based on the larger context of information in the organism. The context contains specified information that is key to the differences.

You could compare this context variability to words in an English text. The same words used in a different context can convey a very different meaning. Words can convey their intended meaning when they are used in a systematic, organized structure composed by an intelligent mind. A hodgepodge of random words can result from non-intelligent actions, but only intelligence can create a meaningful paragraph. What does that tell us when we apply that principle to genetics? Only intelligence can create a meaningful paragraph, and only intelligence can create fruit flies and humans.

The Church Worshiping Together

The Church Worshiping Together

These thoughts were inspired by a good friend who said, “I get a lot more out of sitting on a log in the woods and listening to the birds than I do out of sitting in a pew and listening to a preacher.” Yesterday, we looked at some reasons why the Church needs to gather in prayer. Today, we explore some other benefits of the Church worshiping together.

Worship is not a spectator sport! Every command related to music in worship involves the individual participating in a shared activity. (See Romans 15:9; 1 Corinthians 14:15; Ephesians 5:19; and Colossians 3:16.) Jesus prayed for unity among His followers, and singing together is one of the most unifying things we can do. The purpose is not to entertain God or people. By singing together, we unify, encourage, and build up one another.

The Lord’s Supper, also known as communion, serves as a means to encourage and edify one another. It is not just vertical toward God but also horizontal to your fellow Christians. Remembering the sacrifice of Christ and sharing a memorial provides a way to unify, grow, and be encouraged by the Church worshiping together.

Even giving is not for God’s benefit. God is the creator who made and owns everything. He does not need our money. The Bible makes it clear that giving benefits the giver. (See Acts 20:35; 2 Corinthians 9:7; and 1 Corinthians 16:2.) The person who never learns to give loses in every aspect of life. A good marriage, good kids, good sex, good recreation, and good health all depend on being able to give freely and unconditionally.

People giving through their local congregations can accomplish significant things in the world. Atheists and agnostics take delight in pointing out every mistake that Christians make, but atheism does not primarily address hunger, disease, broken families, mental illness, and homelessness. The Church worshiping together not only encourages and builds individuals, but it also coordinates resources and directs them to meet real needs.

A person may find that “sitting alone in the woods” brings them more personal pleasure than “going to church,” but it will not address the world’s problems or allow them to be part of something bigger than they could accomplish on their own. “Not forsaking the assembling of ourselves together …” (Hebrews 10:25) is not an ego trip for God but a call to action for Christians. The fellowship of the Church worshiping together can have a powerful effect on us individually and on the world.
