Transplanting Animal Organs into Humans

On September 20, 2023, Lawrence Faucette had a pig’s heart transplanted into his body to replace his own heart, which was in total failure. Xenotransplants, transplanting animal organs into humans, have been tried in the past, but the patient’s immune system destroyed the transplanted organ. Faucette’s animal heart came from a pig that was genetically modified to make it more human-like. After a month, there has been no sign of rejection, and Faucette is in physical therapy. The medical science community is interested in xenotransplants because there is a massive shortage of human organs for transplantation. (Update: Unfortunately, Mr. Faucette passed away on October 30, 2023.)

Many people have questioned the religious implications of xenotransplants. Various Bible passages speak of the human heart but not the physical organ. The Old Testament uses the Hebrew word for “heart” 851 times, primarily referring to the mind of an individual. There are a few cases, like Absalom in 2 Samuel 18:14, Nabal in 1 Samuel 25:37, and Joram in 2 Kings 9:24, where the physical heart is intended. In the New Testament, when Jesus talks about the “pure in heart” in Mathew 5:8 or refers to hard hearts, as in Mark 3:5, these are clearly not references to the physical heart.

The bottom line is that God is not primarily concerned with the physical organ but with our thinking, attitude, compassion, and capacity to love and serve. What happens to a person’s body is that it will eventually return to the Earth from which it came. Abraham said in Genesis 18:27, “I am but dust and ashes.” Solomon wrote in Ecclesiastes 12:7, “Then shall the dust return to the earth as it was: and the spirit shall return to God who gave it.” The psalmist wrote, “we are dust” (Psalms 103:14), and we “die and return to the dust “(Psalms 104:29).

Doctors have used valves from pig hearts for a long time, with great benefits for those who receive them. Understanding God’s design and creative wisdom opens the door for transplanting animal organs into humans, providing ways to make a human’s short tenure on Earth more pleasant. However, it is ultimately our soul and relationship with God that is of primary concern. Jesus made that abundantly clear when He said, “Do not fear those who kill the body but are not able to kill the soul: but rather fear him which is able to destroy both body and soul in hell” (Matthew 10:28).

Incredible Color in Birds and Trees

One of the great mysteries of living things is the presence of beauty. If your faith is “survival of the fittest,” you have no explanation for beauty. Things in the natural world often radiate incredible beauty that has no survival benefit or even threatens survival. The incredible color in birds and trees provides a classic example. Some birds have gorgeous colors that can make them vulnerable to predators.

Here in Michigan, we are witnessing another example of beauty with no survival value but seems designed for humans to enjoy. The green color we see in plants is due to chlorophyll, which allows plants to use photosynthesis. There are two kinds of chlorophyll molecules called chlorophyll A and chlorophyll B. Chlorophyll A absorbs blue light, and chlorophyll B absorbs red light. Green light is the highest energy of sunlight reaching Earth’s surface. Plants are green because the green light radiation is reflected away to protect the plants. In the fall of the year, the chlorophyll in the leaves is removed, and we see the remaining colors.

These facts explain why trees are green and the wisdom in the green color of chlorophyll. But why do the leaves have different colors when the chlorophyll is removed? In our area, the first fall colors that appear are the reds of sumac and poison ivy. Depending on the variety, maple trees have various colors of red, orange, and yellow. We also have multiple birch tree varieties, each with different fall colors.

Why should there be different colors we can’t see until the chlorophyll is gone? The chemistry that creates these colors is very complex. From an evolutionary view, all trees would have the one pigment that advances survival, but that is not the case. The picture gets even more complicated when we consider plants that never see sunlight, such as ferns and various grasses.

As we enjoy the incredible color in birds and trees, we can see beauty for the spiritual value it offers and the joy it brings. That is because we are created in the image of God, the creator of beauty.

This Fish Sees With Its Skin

The many unique characteristics we see in animals enabling them to survive give evidence of God’s design and planning. Romans 1:20 says, “We can know there is a God through the things He has made.” Our daily posts here and on Facebook, as well as our Dandy Designs book series, show hundreds of examples. A new example is the hogfish (Lachnolaimus maximus) living in the Atlantic Ocean reefs from the Carolinas to Brazil. You can almost say this fish sees with its skin.

Like many animals, the hogfish’s primary method of survival is camouflage. They hide by changing colors and altering skin patterns. Many animals, such as chameleons, squid, and cuttlefish, have chromatophores, which are pigment-bearing cells that can change color to match the environment. Hogfish also use chromatophores in their skin to change colors, but they have a layer of opsin, a light-sensing protein, under the chromatophore layer.

The hogfish moves through different kinds of background material as the reef has quite varied colors and textures with corals, sponges, and sediment. The fish can change its color to match the environment, but it can’t turn its head to see what color it is. The opsin layer acts as a primitive eye looking at the chromatophores to see that the color matches the surroundings. In that way, this fish sees with its skin.

The design of fish survival in a reef involves a wide variety of techniques. Some can swim rapidly, some can bury themselves in the bottom sediment, and others have immunity to stinging organisms. There are fish who can fly (glide), some can swim in schools, and some, like the Hogfish, can camouflage themselves. Together, they make the reef a place full of life and beauty. Perhaps that beauty will encourage humans to preserve the reefs of the world as places of great aesthetic worth.

Birds Use Spikes to Protect Their Nests

One of the exciting examples of design in the living world is the nesting behavior of birds. We have previously reported on data about birds that nest in peculiar places to protect their eggs and their behavior to thwart predators. We have all seen birds building nests in cliffs or under roof structures, but predatory birds like eagles and hawks can still land on the nests and eat the eggs or baby birds. Scientists have discovered that some birds use spikes to protect their nests from even bird predators.

Researchers in Belgium, the Netherlands, and Scotland found nests in which birds have used long spikes to make it difficult for predators to get to their eggs or chicks. One crow’s nest in Antwerp, Belgium, had 1500 long, sharp spikes. They would make reaching the nest’s occupants extremely difficult for any hawk or eagle. It would also deter other predators, such as cats.

The nests of carrion crows and Eurasian magpies have been found with spike defenses. These birds have used whatever sharp objects they can find in urban areas to build their fortress, including plastic pieces, nails, screws, and knitting needles.

Birds use spikes to protect their nests because God has built into the DNA of various bird species the ability to do unique things to survive. The more we learn about the natural world, the more we should be amazed at the intelligence and design behind all kinds of life on Earth. “We can know there is a God through the things He has made (Romans 1:20).

Preparing for Winter – How Do They Know?

Preparing for Winter – How Do Living Things Know?

The ability of plants and animals to achieve maximum survival success in changing seasons is quite interesting. Here in Michigan, our winters can arrive suddenly and forcefully. It may be 75 degrees one day and below freezing the next. It was quite warm in early September, but many trees were already preparing for winter. The leaves of our sumac trees became brilliant red and started falling off the branches. As we approach the end of September, some species of maple trees are changing colors and dropping their leaves.

Several species of birds have left Michigan, heading south for the winter. We live on a river where we see a massive increase in fish activity. There is also a significant increase in the activity of insects, with some butterflies, such as monarchs, heading south in groups. The number of cocoons in our bushes and in our house has accelerated, and some species of bees and wasps have become more aggressive.

The big question is how living things seem to know it’s time to start preparing for winter, even when there is no significant temperature change. There have also been no clues from other weather factors like humidity, rainfall, wind velocity, and direction. The scientific evidence shows that living things pick up on less obvious signals that say, “Winter is coming, and you need to prepare.”

Some living things sense the length of daylight, telling them to prepare for winter. Another factor is the angle of the Sun’s rays, which controls what kind of light reaches Earth’s surface. The Sun’s light contains a variety of wavelengths. The higher energy wavelengths are refracted and scattered more than the longer, lower energy forms. The sky is blue because blue light has higher energy than the rest of the visible spectrum and thus is scattered and refracted more. The next highest energy wavelength is green. Plants are green because they reflect that color, protecting them from the next highest energy of light that reaches Earth’s surface.

As the Sun gets lower in the sky, wavelengths we can’t even see, such as ultraviolet, are refracted and scattered away from the surface. Living things detect that change and start preparation for winter. Explaining how this system of life came into existence is a real challenge for those who deny God’s creation of our planet and the life on it. It’s a joy to see the things God has made testifying about His intelligence and design as they start preparing for winter (Romans 1:20).

Honey Buzzard Migration

The more we learn about bird and insect migrations, the more we are astounded by how they do what they do. Chance explanations fail when the migrations become complex. The honey buzzard migration is another example of an incredible migration that defies chance explanation.

Researchers using a satellite tracking system in Finland released data on a bird known as the European honey buzzard. This bird actually does eat honey and will search out the nest of bees and hornets to find its food. Scientists knew that this bird spends its austral summer around the town of Reitz in Free State, South Africa, where bee nests are abundant. They tracked the honey buzzard migration as it left Africa on April 20th and arrived in Finland on June 2nd at the time when, once again, its favorite food was available. This bird enjoys summer twice by its migration, securing food and avoiding winter, but its route is very complicated.

You might think the honey buzzard would just head north, but that would involve going over dangerous landforms and climate irregularities. Instead, the bird makes a 90-degree turn at the source of the Nile River and follows it. When the bird reaches the end of the Nile, it returns to the same longitude line where it started, avoiding the Mediterranean and the Sudan to eventually reach its destination in Finland.

Honey buzzards cover 10,000 kilometers in 42 days, averaging 230 kilometers daily. If you want to see honey buzzards attacking a bee nest, do a word search on the web, but don’t expect an explanation of its migratory route. The honey buzzard migration is programmed into the bird’s DNA, and how the program got there is another example of design by intelligence. Instinctive drives defy chance explanations because they involve a changing Earth with landforms and climate factors that happen too fast for gradual accommodation. We suggest that honey buzzard migration is another evidence of God’s design for all life forms in the creation.

North American Curly Horses and Evolution

One of the great tragedies of the evolution/creation war has been the failure of people on all sides to define what they mean by “evolution.” We see a classic example in North American Curly Horses, sometimes called the American Bashkir Curly. This breed of horses has a heavily curled coat in the winter, and a much thinner coat in summer, when the mane and tail molt.

The curly coat is an advantage during very cold weather. In addition to the unusual coat, North American Curly Horses are well known for various other characteristics. They are much quieter in disposition than other horses and have thicker bones, rounded hooves, and exceptional memory. Curly horses are the only hypoallergenic horse breed – good news for people allergic to horses.

Horses can be traced back to the time when their ancestor was a small creature about the size of a dog. The best-known fossil horse is eohippus, sometimes called the “dawn horse,” but other forms of horses based on fossilized remains are merychippus, mesohippus, and miohippus. North American Curly Horses are hypoallergenic because a protein that most horse-allergic people react to is absent from their hair. Horse ranchers are cross-breeding curly horses with other breeds to establish some of their characteristics in other breeds.

North American Curly Horses are another example of how humans have benefited from evolutionary change. This evolution is not part of a theory to deny God as the creator. The design of life that allows change in this way is an excellent testimony to the wisdom and intelligence of God’s creation. When God created the first horse, He built into its DNA the genes that would allow change. We can say the same of the many other plants and animals humans need to survive on this planet.

Evolution of species is an excellent proof of the existence of God, but don’t confuse it with creation. They deal with two different things. Creation produced the first horse-like animals, and God’s design of life allowed them to change into the North American Curly Horses and other breeds we have today.

An Octopus Garden

One of the more interesting creatures in the ocean is a small octopus called the pearl octopus (Muusoctopus robustus). They get their name because they look like pearls on the dark ocean floor. Because of their small size, they are easy victims of predation. They have no defense mechanisms and are an easy meal for various predatory ocean creatures. How do they continue to thrive in their Pacific Ocean habitat? The answer lies in an octopus garden.

Researchers discovered the octopus garden 80 miles from the central California coast at a place called the Davidson Seamount. A seamount is an ancient volcano that has either sunk into the ocean floor or has been covered by rising ocean water. The Monterey National Marine Sanctuary and Monterey Bay Aquarium Research Institute have studied deep-sea corals on this seamount for 20 years. They recently discovered an octopus garden – home to at least 6,000 nesting pearl octopuses and perhaps as many as 20,000.

The design of this “garden” offers successful reproduction of this vulnerable species. By being 10,500 feet down, they avoid many octopus predators simply because they don’t feed that deep. Like many other forms of life, synchronized birthing floods the area with offspring so a predator can’t wipe out a whole population. Hydrothermal springs at the base of Davidson Seamount warm the water, allowing the pearl octopus eggs to hatch much faster.

We see many remarkable designs in the biological world, allowing animals to survive. Every nook and cranny of the planet is home to some form of life, and this is just one more example. As Romans 1:20 says, “We can know there is a God through the things He has made.”

Siphonophores – A Colony of Animals Living as One

The more science learns about the biological world, the more unique things we see. Most of us know about jellyfish, corals, and anemones. These ocean animals are members of the phylum Cnidaria. In that phylum, a strange order named Siphonophorae has 175 species. The Portuguese man o’ war is a member of the order of siphonophores.

Siphonophores may look like one organism, but they are actually colonies consisting of thousands of clones that function in different ways. Siphonophores start with a single “bud” called a zooid. The zooid replicates itself asexually, producing thousands of clones. Each clone has a specific job, such as eating, moving, or reproducing.

The colony of clones functions together as if they were one animal. For example, the Portuguese man o’ war has gas-filled zooids, allowing it to float on the ocean’s surface. Other zooids capture prey, while others digest the food. The individual zooids rely on each other for survival as one large functioning colony we call the Portuguese man o’ war.

In 2020, scientists found a siphonophore that was 150 feet long, probably the world’s longest animal. Most siphonophores live in the darkness of the deep oceans and are bioluminescent, using chemicals to produce light that attracts prey. The Portuguese man o’ war is an exception as a siphonophore that lives on the ocean’s surface.

The deep sea diving expeditions of the Schmidt Ocean Institute and the EV Nautilus have taught us much about the designs built into living things that allow life to exist in places totally alien to humans. Siphonophores make us realize that planet Earth is a wonderfully designed and unique place in the universe, full of amazing living creatures. We must treasure God’s gift and take care of it instead of abusing and polluting it.

The Problem of Homochirality

Can life arise spontaneously from non-living chemicals? Scientists have spent many hours and vast amounts of research money attempting to prove it can. One of the many challenges they must solve is the problem of homochirality.

All the large molecules required to make a living cell are composed of building blocks that have mirror images. When you look in a mirror, you see a reversed image of yourself. The right hand appears to be on the left and vice versa. The right- and left-hand analogy is used when referring to the building blocks of life. Those building blocks come in either right or left-handed forms. We call that handedness “chirality” from the Greek word for hand. Homochirality means having the same handedness.

Life almost exclusively uses only one chirality. The amino acids that make up proteins are left-handed. Scientists are uncertain why, but they have to accept the fact that to build the proteins that RNA and DNA molecules require for life, you must have only left-handed amino acids.

In nature, amino acids are not homochiral. They come in a distribution of about 50/50 left and right, creating the problem of homochirality. For amino acids to form the building blocks of life, they would have to be homochiral. Scientists have yet to find a way to make that happen, even in the laboratory. They aren’t even sure why life requires it since the chemical properties of mirror-imaged compounds are the same for all practical purposes.

The problem of homochirality is one of the many obstacles that prevent non-living chemicals from coming together to form life without intervention by an intelligent force. Even the intelligence of our best scientists has not overcome those obstacles. I saved an Associated Press news release from 2007 titled, “Scientists Believe Artificial Life Will Be Possible in 3 to 10 Years.” We are well past that goal, and I suspect they are not much closer today.
