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?

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.

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.

Genetic Difference Between Humans and Chimpanzees

Genetic Difference Between Humans and Chimpanzees

The media has popularized the myth that the genetic difference between humans and chimpanzees is only 1%. Recent research shows that the variance is 15% or more. What we have here is the old graduate student mentality: “Make sure your data conforms to your conclusions.”  If you are trying to prove that humans came from apes and that genetics supports that faith, you cannot accept the 15% data. The result is the popular 1% myth.

The Bible is silent on how God made the human body, stating only that He formed it “of the dust of the earth” (Genesis 2:7 and 3:19). These verses use the Hebrew word “yatsar,” meaning to form as a potter would shape a vase from clay. The Bible does not tell us how God formed the first human or how long He took to do it.

One thing is clear: both men and women are created in the image of God (Genesis 1:27). This refers to the human soul, not the physical body. God is a spiritual being, not a physical one. Humans are uniquely endowed with a soul, a spiritual component that distinguishes humanity from all other life on Earth. The human soul enables us to create music and art, to worship, and to develop the capacity for critical thinking. We are not driven by instinct as animals are.

Some physical components of the human body are similar to those of chimpanzees. Stereoscopic vision, an opposable thumb, and body hair are some genetic similarities. The fact that the genetic similarity between humans and chimpanzees is 85% should not be surprising, given that fruit flies share 60% of their genes with humans. God has used the best design in many features of all animal bodies.

What separates humans from animals is our spiritual makeup, not our genes. However, the 1% genetic difference between humans and chimpanzees is a myth.

The Design of the Woodpecker’s Tongue

The Design of the Woodpecker’s Tongue

One of the great questions ornithologists must answer is how a woodpecker can pound its beak on wood day after day without suffering brain damage. In previous articles, we have talked about the shock-absorbing features of the woodpecker’s skull. Researchers have learned more as they study the design of the woodpecker’s tongue.

Woodpecker tongues are much longer than their beaks. The design of the woodpecker’s tongue extends back into the skull, wrapping around the brain and looping around the eye socket. Woodpeckers slam their beaks into wood 20 times per second, and the tongue’s unique path acts like a biological seatbelt, distributing impact forces and protecting the brain. The woodpecker’s specialized hyoid apparatus (tongue-supporting bone and soft tissue) is a design feature that helps protect its brain from concussions.

Oak trees line our home office by the St. Joseph River in Michigan. We have five kinds of woodpeckers, ranging from the large pileated woodpecker to the downy woodpecker, which is the size of a house sparrow. Watching wood chips fly as they hammer at the oak trees to reach insects reminds us of God’s design and the impossibility of it resulting from chance mutations.

The Bible calls us to look at the evidence. The more we see, the more we realize that atheists and biblical skeptics must deny more and more of what science learns. As we look at the creation, we see the Creator’s wisdom, even in the design of the woodpecker’s tongue.

Why We Care About Entropy

Why We Care About Entropy

As a high school physics teacher, I frequently found myself challenged to keep my students interested. Some subjects were easy, but others were challenging, and the kids became bored very quickly. An example of the latter was a unit on the laws of thermodynamics. The second law, also known as the entropy law, states that a closed system tends to become increasingly disordered over time. Entropy is a statistical measure of disorder. During that unit of study, I once had a student who said, “Who cares?” There are good reasons why we care about entropy.

My response is that entropy is a design feature of the cosmos that produces black holes, but it also allows us to breathe and have engines in our cars. As a public-school teacher, I could not bring my religious views into the classroom, but it also disproves one of the atheist arguments against the existence of God.

When we say that God has always existed and He created the cosmos, atheists ask, “Then who created God?” They suggest it is easier to believe that matter has always existed. Why we care about entropy is that it shows that matter and the cosmos have not always existed.

Every reaction in the physical world reduces the amount of energy available to do work. The total energy in the cosmos available to do work is constantly decreasing, eventually becoming zero, and entropy will be maximum. That means the cosmos could not be eternal, and it must have had a beginning. There must be a cause for that beginning, and that cause is God.

Only Humans Can Sing

Only Humans Can Sing

The claim that animals sing just like humans is based on misinformation. Only humans can produce music, a fact supported by both definition and experience. A dictionary definition of music is: “The art of arranging sounds in time that expresses ideas and emotions to produce a continuous, unified, and evocative composition through melody, harmony, rhythm, and timbre.” The dictionary also gives the following definition of singing: “The use of the human voice to provide a succession of notes to produce a desired effect.” Only humans can sing.

Music has a proven effect on humans. My son Timothy was born with multiple handicaps. He was blind, severely mentally challenged, and had cerebral palsy, muscular dystrophy, and schizophrenia. What Tim did not have was a problem with his hearing. If we put on a record of one of his favorite artists, he would smile and sit quietly through the entire record.

The Bible records the effect of music on humans. King Saul was mentally disturbed. The one thing that gave him peace was David and his harp (1 Samuel 16:14-16). The Old Testament includes many references to the role of music. In Daniel 3:5-15, we read that Nebuchadnezzar, king of Babylon, used music to call people to worship his gold image. In Ecclesiastes 2:8, we read that Solomon had singers serving him. In Nehemiah 12:27-28, we see that singers and players celebrated the dedication of the restored Jerusalem wall. The Psalms are songs, and many of them refer to making music.

Music has played a significant role in Christianity. Ephesians 5:19 tells Christians to “Speak to one another with psalms, hymns, and spiritual songs.” A psalm is a current expression of needs. A hymn is a song of praise to God. Spiritual songs are songs that instruct or motivate. In recent years, Bill Gaither and others have popularized gospel music.

Can animals do these things? The answer is no. Only humans can sing. Animals make sounds and “songs” for survival purposes. Dogs bark, cats meow, and birds “sing” for survival reasons. Whales in the broad expanse of the ocean contact one another by emitting low frequencies that travel long distances. A cardinal sits outside our window and “sings.” But what is he actually doing? He is saying to all other cardinals, “Stay out of my territory and away from my mate or else.”  He is not creating music.

Animal communication is a demonstration of God’s design and wisdom, but only humans can sing as a product of our spiritual nature in God’s image. Humans need to sing and make music. See Colossians 3:16 and Hebrews 2:12. God created us to enjoy the gift of music and use it to honor Him.

Nighttime Pollinators Are Essential

Nighttime Pollinators Are Essential
Moth on a Lilac

There is considerable media discussion about the plight of bees, attributed to the use of insecticides and to climate change. The media overlooks the fact that bees and butterflies are primarily daytime pollinators. Of the approximately 350,000 flowering plant species, some depend on nighttime pollinators.

The long list of nighttime pollinators includes moths, cockroaches, beetles, slugs, snails, and bats. Many people consider them to be pests, especially cockroaches and beetles. For this reason, they target pollinators by applying chemicals to control them. The result is that desirable plants fail to reproduce and die out.

The answer to this problem is helping people understand the importance of being cautious about what they apply to their plants and why. Christians believe that God has designed all ecosystems, and good stewardship requires protecting what He has given us. People who reject God’s design for life are engaged in chemical warfare, in this case, against nighttime pollinators.

Roadrunners Run in the Desert

Roadrunners Run in the Desert

In the Warner Bros. cartoons, the Road Runner was always outrunning and outsmarting Wile E. Coyote. In real life, roadrunners can run up to 20 miles (32 km) per hour. Although they can fly, when not escaping predators, roadrunners spend most of their time on the ground. There are two species. The greater roadrunner (Geococcyx californianus) lives in the deserts of the southwestern United States and Mexico. The lesser roadrunner (Geococcyx velox) lives in Mexico and Central America. 

Roadrunners are members of the cuckoo family, and like other cuckoos, they have four toes, with two facing forward and two facing backward. When they run through the dust of the desert, they leave tracks that resemble the letter “X,” making it difficult to tell which way they are going. The greater roadrunner is almost 2 feet (60 cm) long from head to tail. The lesser roadrunner is smaller. They eat nearly anything they can find in the desert, even scorpions and snakes. Due to their speed in capturing prey, the greater roadrunner can eat poisonous snakes, including rattlesnakes. 

In the cartoons, the Road Runner makes a sound like “beep beep.” Real roadrunners sound more like the cooing of a dove. Roadrunners don’t migrate, and they stay in their breeding area year-round. They are monogamous and mate for life, with the male and female taking turns incubating the eggs and caring for the young. 

Regardless of what happens to Wyle E. Coyote, he always comes back to try to capture the elusive Road Runner. Desert life is a delicately balanced system. Life in the real desert may not be as funny as in the cartoons, but it’s worth learning about because God’s creations are always fascinating.
