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.

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.

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
Pileated woodpecker feeding young

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.

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.

Ice Crawlers and Ice-Worms

Ice Crawlers
Ice Crawler

As humans enjoy spring’s warmer weather, we are reminded of extremophiles that can only survive in the cold. They include ice crawlers and ice worms.

Ice crawlers (Grylloblatidae), also known as icebugs, are about an inch (3 cm) long. They are nocturnal, spend the daytime under snow, and then emerge at night to forage for dead insects and plant material blown by the wind. They live under logs and deep in crevasses in warmer weather to stay cold. Ice crawlers have no wings and only diminished eyes. Their optimal living temperature is 34-39 degrees F (1-4 C). Lower or much higher temperatures can kill them. They survive on glaciers and ice sheets.

Ice-worms (Mesenchytraeus), also called glacier worms, survive in glacial ice and eat algae and bacteria that live there. They spend their entire life cycle at 32 degrees F (0 C) or lower and will die if the temperature goes above that. These tiny worms move between the ice crystals using small bristles called setae.

Birds that live in high-altitude snow and ice fields feed on ice worms and ice crawlers.  Snow buntings stay in the ice fields year-round, and other birds stop there during migration in the spring and fall.

Many years ago, my daughters and I were on a snowmobile trip in Jasper Provincial Park, Canada. We gazed down into a crevasse and marveled at the beautiful blue color, free of any dirt lines. It was so pure that the ranger guiding us gave us a cup of melted glacial ice to drink. He said a biologist told the park service that the melted glacial ice was safer to drink than distilled water. I questioned that statement, but now we know that ice crawlers and worms do an incredible job of keeping the snow and ice pure. There were birds all around us during that visit, but it was years later before I learned that birds like snow buntings exist.

God’s design of every part of Earth’s biosphere has unique conditions, requiring living things to have special equipment to survive there. The more we see the Earth’s varied environments, the more we see God’s wisdom and creation around us.

Microplastics and Dementia

Microplastics and Dementia

You may have noticed that dementia is much worse today than it was in the past. Part of that is probably due to people living longer, but life expectancy has not increased enough to fully explain the growth rate of dementia. Perhaps there is a connection between microplastics and dementia.

Researchers from the University of New Mexico have found an amazing correlation between dementia and the concentration of microplastics in human brains. A study of specimens from autopsies found that the brains of people with dementia had as much as five times more microplastics than normal brains. Comparisons of brain tissues from 2016 and 2024 show 50% higher concentrations in the 2024 samples.

Global plastic production doubles every 10 to 15 years, so the problem is only going to get worse. The human brain is designed with a barrier between blood vessels and brain tissue, but some people have weak blood-brain barriers. Skeptics suggest there is a design failure in the human brain because it evolved by chance over time. A better explanation involves human failure to protect our health.

The fact is that pollution is apparently a significant cause of dementia. Like cancer, brain problems are linked to human greed and a failure to use what God has given us as a tool for successful living. Reducing the flow of microplastics into the environment is going to be an uphill battle because cheap alternatives to plastics are not available. Meanwhile, more studies are needed on the connection between microplastics and dementia.

Male and Female Bodies are Different

Male and Female Bodies are Different by Design

“Failure to protect the female category in sports is one of the most egregious forms of violence against women and girls.” Those are the words of Reem Alsalem, the United Nations special rapporteur on violence against women and girls, who reported that female athletes have lost nearly 900 medals to males competing in the female category. The scientific fact is that the male and female bodies are different by design.

This website deals with evidence and promotes the concept that science and faith are friends, not enemies. Stating that since Genesis 1 says God made Eve from Adam’s rib, men and women are the same is a misunderstanding of the biblical message. We are all one spiritually, not physically. In Galatians 3:28, we read, “There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus.” Obviously, that is not true physically, but it is true spiritually, so those who quote this passage to say that there should be unity in all sports are not understanding the Bible.

The fact is that male and female bodies are different by design. Males and females have different-sized muscles, pelvises, and skeletal structures. You will never see a female fullback in the NFL or a female center in the NBA. You will never see a male giving birth to a child, even if an embryo was in some way placed in a male.

This issue has become a political manipulation. The tragic end of medical techniques used to control hormones and surgically alter genitalia will become clear. Those who have had transgender medical procedures as children will realize that their life expectancies have been drastically reduced and their relationships terminated by a decision made when they were too young to understand the consequences.

Genesis 2:24 says, “A man will leave his father and mother and be united to his wife, and they will become one flesh.” In Genesis 2:18, we read, “It is not good for man to be alone. I will make a helper suitable for him.” God created woman to do what man could not do on his own. Trying to change what God created will not work because male and female bodies are different by design. God intended the sexes to work together, fulfilling the roles He gave them.
