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.

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.

Our Pets Don’t Have Souls

Our Pets Don’t Have Souls

Domestic animals make our lives full and sometimes are our best friends. Some people ask whether animals go to heaven, or say they won’t be happy in heaven if their pet isn’t there. Saying that our pets don’t have souls is very emotionally loaded.

I am an animal lover and have had eight dogs and three cats, all of which I loved dearly. I know what wonderful companions animals can be and how much they can enrich our lives. I also know that for some people, animals have been their primary link to sanity. People have called dogs “man’s best friend” because they don’t have the limitations of many humans. Animals trust, obey, remain faithful, are always truthful, always positive, always loving, and are always there. Our human relationships are likely to fail all these tests. Animals frequently serve as the needed equilibrium for people who have been hurt in their human relationships.

Please think carefully about the previous paragraph. It is a severe indictment of the Church. When I hear someone say that their dog is the only friend they have in the world, I know the Church has failed them. God intended for the Church to be the one force in our lives that would never let us down, but that has rarely been the case due to human weakness.

With those things in mind, the fact is that animals are not humans. The Bible makes it clear that humans are uniquely created in the image of God, giving us characteristics that animals don’t have. Our pets don’t have souls and are not the final answer to the isolation some of us feel.

When we are in heaven and no longer bound by time, will we be able to go back and revisit the animals that blessed our lives? I have no idea, but I believe our priorities and relationships will be different then. The Church often fails to support people who are hurt, isolated, lonely, and unfulfilled. I hope we will begin to do a better job of healing them with our love, compassion, and fellowship.

Take It Easy and Live Longer

Ocean Quahogs Take It Easy and Live Longer

It’s an animal that can live for 500 years. The ocean quahog (Arctica islandica) is a clam native to the North Atlantic. They exemplify the slogan “Take it easy and live longer.”

The ocean quahogs living in deep, cold waters farther north live the longest. Those in the southern areas tend to have much shorter lives. Since these mollusks add one growth line to their shells each year, it’s possible to determine the age by counting the lines. The oldest reported specimen found in 2006 was 507 years old. That means this clam began its life shortly after Columbus discovered the Americas. Who knows how much longer it might have lived if it had escaped capture.

Ocean quahogs and a few other animals, such as tortoises, have a quality that scientists call “negligible senescence.” What that means is they don’t show signs of aging. Scientists are still trying to discover the factors that allow some animals to live long lives without apparent aging.

We suggest that one factor is obvious. “Take it easy and live longer” is demonstrated by the long-lived creatures with an unhurried and unstressed lifestyle. Perhaps we can learn something from that. The Creator had a reason for setting aside a time of rest.

Dancing Frogs in India

Cartoon Dancing Frogs
Real Dancing Frogs

If you can imagine a male frog sticking his leg up and waving his foot to attract the attention of a female frog, then you have a mental picture of “dancing frogs” (Micrixalus). Several species of these frogs live in the Western Ghats Mountain Range of India. Although these dancing frogs can’t dance like the cartoon version, with top hat and cane, they are gifted at sticking a leg out. 

During the mating season, the male dancing frogs will find a prominent rock along the stream and puff out their white vocal sacs. Then they tap their hind foot on the rock and wave it in the air when they see a good-looking female frog approaching. They sometimes wave their foot when another male comes along to tell him, “This is my territory, and you better move along, buddy!” The frog may use alternate hind legs to perform this “foot flagging” while at the same time expanding its vocal sac to call out to the females. It’s a frog-style song and dance routine. 

After mating, the female uses her hind legs to dig a hole in the streambed to bury the eggs. Dancing frogs are vulnerable because of habitat loss, but India has created some protected areas in the Western Ghats, a biodiversity hotspot. We are continually amazed at the diversity and creativity in the beautiful system of life God created. We even find it entertaining.
