The Blessing of Beauty

Yesterday, we talked about the problem of beauty. The question is: “How could natural selection acting on random mutations create beauty which seems to have no survival value?” I suggested that natural selection acting on blind chance mutations cannot explain all of the beauty we see in animals and plants. Let’s continue to think about this as we examine the blessing of beauty.

The blessing of beauty involves more than just visual beauty. A humpback whale’s intricate and beautiful song lasts for half an hour. Does it have anything to contribute to the survival of these mammals? Well, in a way, it does. When human technology reached a point where the humpback’s song could be heard and recorded in the 1960s, more people than whale hunters got a chance to hear it. The exposure of that song to the general population of humans played a large part in the passage of laws preventing the slaughter of those animals. But that is evidence for human appreciation of beauty, not evolutionary natural selection. For those who suggest the male humpbacks use their songs to attract females, there is little to no evidence that the females are even paying attention.

No proponent of Darwinian evolution would suggest that humpback whales are even remotely related to nightingales, but those birds also contribute to the blessing of beauty. They sing long, complex, and beautiful songs, but rather than singing into the ocean, nightingales sing from twilight into the night. As those small birds sit on a branch singing, they make themselves easy prey for predators. Instead of singing for hours in the darkness, why don’t they just be quiet and stay safe until morning?

When scientists tape-recorded nightingales and slowed down the tape, lowering the pitch a couple of octaves, they discovered something very interesting. The result was that the nightingale’s song sounded much like the song of a humpback whale. On the other hand, if you take the humpback whale song and speed it up while raising the pitch, it compares to a nightingale’s song. Why should they be so much alike? Evolutionists like to call this sort of thing “convergent evolution.” I have another suggestion. Perhaps they got their music from the same original Composer.

Since the beauty of bird songs often goes beyond attracting mates for the survival of the fittest, do the birds sing because they love to hear music? I think they are merely doing what their Creator programmed them to do. But why did God design and program these animals to sing? Perhaps the blessing of beauty is God’s gift to us. Beauty brings us joy, eases our stress, and touches our emotions. Because God loves us, He created beauty for us to enjoy. The beauty around us provides an earthly sample of the beauty God has planned for us beyond this life. In other words, beauty is another evidence that God exists. With that in mind, the problem of beauty becomes the blessing of beauty.

Tomorrow, we will look at how beauty was a problem that, according to Darwin, “makes me sick.”

The Problem of Beauty

One of the challenges that skeptics use to argue against the existence of God is often called “the problem of pain.” The argument goes something like this: “Why would an all-powerful and loving God allow pain and suffering?” We have dealt with that problem before, including on our website whypain.org. However, there is a contrasting argument for the existence of God that some have called “the problem of beauty.”

The problem of beauty asks the question: “How is it possible that evolution by natural selection could create such beauty in living things?” In other words, “How could natural selection acting on random mutations create beauty which seems to have no survival value?” Darwinian evolution operates on the survival of the fittest. So how can the seemingly simple process of natural selection or survival of the fittest explain many cases of beauty which seem to make animals less fit and thus less likely to survive?

Look around, and you will see beautiful designs that naturalistic evolution attempts to explain without a designer. Why do male cardinals have the beautiful red color? Why do butterflies have such exquisite designs and colors? Some animals display beautiful colors that make them more vulnerable to predators. Birds make sounds that we can describe as beautiful music. A male bird may sing for an hour, announcing himself not only to prospective mates but also to predators. How can those beautiful features promote the survival of the fittest?

Peacocks, lyrebirds, flowers, starfish, butterflies, and seashells all display beautiful features that cannot be fully explained as survival benefits. In some cases, they may be at least partially explained by mathematical principles. But then, where did mathematical principles in our three-dimensional world originate except from the Creator of all things. Why does the nightingale sing beautiful songs to the darkness? Why do some lizards display colorful crests? How can colorblind cuttlefish change their colors at will not just to camouflage but to send messages to other cuttlefish or predators or just to dazzle any observer? Why do flowers display not only beautiful colors but also soothing fragrances? The beauty of nature is visual, auditory, and even fragrant. Most of all, it is priceless.

It seems that natural selection acting on blind chance mutations cannot explain all of the beauty we see in living things–both plants and animals. If natural selection can’t explain it, does that indicate evidence for design by an Artist? Furthermore, how can we explain the fact that humans can recognize and appreciate beauty? Is that because the Artist created us in His image? These questions point out the problem of beauty. I hope you will join me as we continue to consider this problem tomorrow.

Phenotypic Plasticity and Life

Red Eared Slider Turtle and Phenotypic Plasticity — Red Eared Slider Turtle

There are so many examples of design in God’s creation that we often overlook them. One example that has been a problem for evolutionists is the cause of the variability of traits in organisms. Scientists call it phenotypic plasticity. For example, what determines whether the sex of an offspring is male or female? Biologists tell us that it is a matter of genetics, but that isn’t always the case.

When a red-eared slider turtle deposits her eggs, the place where she lays them determines the sex of the baby turtles. If she lays her eggs in a cool place, the babies will be males. If she lays her eggs in a warm sunny spot, the baby turtles will be females. The environment where the eggs are laid controls the ratio of males to females and limits the time of year when more females will be available to produce more offspring.

Sometimes the physical shape of an animal and its diet are determined by the environment in which it finds itself. The Mexican spadefoot toad is a classic example. The tadpoles of this toad will typically feed on plankton and algae, but occasionally a tadpole will find itself in a pool that is rich in fairy shrimp. The shape and diet of the tadpole that has eaten the shrimp will change. It now becomes a carnivore with a broad head and a new shape ideal for fast swimming.

We also see this ability to change as a function of environmental conditions in some plants. For example, cabbage white butterfly caterpillars sometimes attack wild radishes. When this happens, the plant immediately begins producing chemicals in its leaves to repel the caterpillars. Trait variability is a significant issue in evolution. In Charles Darwin’s book On the Origin of Species, he spent the first two chapters trying to explain this problem, but he never succeeded.

The ability to change as the environment changes is a design feature of many life forms. Phenotypic plasticity is a testimony to the wisdom and design that God built into all life.

Drifting Along With the Breeze

Plants disperse their seeds in various ways. Many of them allow their seeds to be carried away by the wind. A method used by other plant species involves allowing the entire plant to go drifting along with the breeze. We call them tumbleweeds.

Tumbleweeds have often been associated with the American southwest, but they exist in primarily arid or desert areas in many countries of the world. A tumbleweed is simply a plant that breaks off from its roots and rolls along in the wind. Sometimes only part of the plant carrying the seeds breaks off. Also, some plants that produce spores rather than seeds become tumbleweeds.

As the plant is drifting along with the breeze, it scatters the seeds or spores over a wide area. This seed dispersal system works well in dry, open, windy areas. Unfortunately, sometimes it works too well. Humans have accidentally transported tumbleweeds from their native environments into new areas where they become invasive species. Sometimes they get caught in fences or get tangled with each other. These tumbleweed clusters can even grow large enough to block roads or houses. On the other hand, tumbleweeds can be beneficial by serving as food for animals or livestock in the dry rangelands. What could be better than for your food to come drifting along with the breeze right to you?

For the tumbleweeds to disperse their seeds and bring new life, they have to die first. As the dead plant degrades, the seeds are released, and new life begins in the desert. Jesus Christ said, “Unless a kernel of wheat falls to the ground and dies, it remains only a single seed. But if it dies, it produces many seeds” (John 12:24). Jesus spoke those words knowing that He would soon give His life. However, from His death would come new life for all who will accept it because He rose to conquer death. Jesus was not just drifting along. He knew exactly what he was about to do, and He did it for you and me.

Unusual Properties of the Sacred Lotus

People sometimes call them “water lilies,” but that term applies to a different plant species. The sacred lotus (Nelumbo nucifera), also known as Indian lotus, is a flowering tropical aquatic plant. Its roots are planted in the bottom of a pond or slow-moving stream while the leaves float on top of the water. The distance from the roots to the leaves may be around 5 feet (150 cm). The spread of the leaves may be about 10 feet (3 meters), and the flowers about 8 inches (20 cm) in diameter. Let’s examine some unusual properties of the sacred lotus.

One of the unusual features of this plant is its ability to regulate its flower temperature. Even if the air temperature drops to 50 degrees F (10 degrees C), the flower can remain at around 90 degrees F (32 degrees C). This temperature regulation can attract cold-blooded (ectothermic) insect pollinators to the flowers. Mammals and birds are warm-blooded (endothermic) because they produce heat by the oxidation of nutrients, but it’s very unusual for a plant to produce heat to warm itself.

That’s only one of the unusual properties of the sacred lotus. The plant is a perennial, meaning it survives from year to year. As long as the water remains, an individual lotus plant can last for many years. However, if the water dries up, the lotus seeds can survive for extended times. The sacred lotus often grows in river floodplains, where they deposit their seeds on the bottom. When the floodplain dries up, the seeds that wildlife don’t eat can become buried in dried mud. When water returns, the seeds germinate and grow to a new abundance of sacred lotus plants, even after a dormancy of hundreds of years. For example, a 1300-year-old lotus seed found in a dry Chinese lakebed germinated and grew after planting.

Another of the unusual properties of the sacred lotus is that even when it grows in dirty water, it remains clean. That’s because of what is known as ultrahydrophobicity (super water-repelling). People have noticed this property of the lotus plant for centuries, if not millennia. However, scientists could not explain it until the invention of scanning electron microscopes. The leaves are covered with microscopic (or nanoscopic) papillae (or bumps) with a waxy surface. These surface features cause the leaves to shed water aggressively. Water can’t wet the leaves, so the water’s surface tension forms spherical droplets that adhere to dirt and run off the leaves carrying the soil along with any harmful fungi and algae.

Science has imitated the lotus leaf surface to create paint that cleans itself in the rain, fabrics that shed water, and other products. This is only one of many “natural” inventions that people have copied and taken credit for, even though God actually invented them.

Wildfires Can Be Beneficial

We have all seen the heart-wrenching pictures of people who have lost their homes to wildfires. Several years ago, we were in the area around Mount Lassen in California and saw how a very hot fire reduced a vast area to dust– including homes, cars, and electric power lines and towers. Of course, some people criticize God’s design when a wildfire devastates an area, but wildfires can be beneficial.

The National Science Foundation funded a 35-year study in Minnesota which showed that periodic wildfires can inhibit plant disease. Oak wilt is a fungal pathogen that can devastate groves of oak trees. The NSF study showed that areas that experience periodic wildfires have a much lower incidence rate of oak wilt than areas with no fires. The difference is striking, with a 765% reduction in oak tree mortality in burned areas over unburned areas.

The NSF report mentions that very little long-term research has been done on fire and plant disease interactions. We can’t blame God for poor design causing wildfires. Studies have shown that many wildfires are caused by poor human management of ecosystems. When people allow forest litter to pile up, the potential for destructive wildfires increases dramatically. How people maintain their properties contributes to wildfire damage to homes in residential areas. With climate change causing higher temperatures and severe droughts in areas with large human populations, wildfires will cause more damage.

The research shows that wildfires are a functional part of controlling invasive attacks on local plants in the natural world. So God’s design is not flawed, but human errors in managing what God has given us have brought great pain to many people. The question is whether we will learn from the past.

Science has given us tools to understand that wildfires can be beneficial in the natural world. Will we continue to promote ignorance of how the natural system works and bring tragic results to people living in areas vulnerable to wildfires?

Extreme Plant Design – Rafflesia

The world’s largest and most awful-smelling flowers grow in the rain forests of the Philippines, Malaysia, Indonesia, and Thailand. They are produced by about 28 species of plants in the genus Rafflesia. These examples of extreme plant design have the odor and even the appearance of rotting flesh.

Rafflesia are parasitic plants that grow under the bark of woody vines in the genus Tetrastigma. The vines of Tetrastigma are also parasitic plants that use host trees to reach sunlight for photosynthesis. So you could say that makes Rafflesia plants parasites of parasites. Rafflesia plants grow inside the Tetrastigma vines so that their only visible part is the flower. They have no roots or stems.

The Rafflesia flowers have five petals and can be 40 inches (100 cm) or more in diameter and weigh 22 pounds (10 kg) or more. Because of the odor of these flowers, they attract flies and insects that feed on dead animals. Those insects transfer pollen from the male flowers to the female flowers, which the males outnumber.

But that isn’t the end of this extreme plant design story. Tetrastigma vines have a defense mechanism to prevent the Rafflesia from growing and taking energy from them. They produce chemicals called benzylisoquinoline alkaloids that are related to morphine and codeine. Those chemicals sometimes prevent the Rafflesia from growing in the Tetrastigma vine. However, it doesn’t work all the time. Jeanmaire Molina, a plant biologist at Long Island University, is trying to find out why. She thinks that Rafflesia may have a way to suppress the Tetrastigma’s alkaloid production.

Scientific American magazine quoted Harvard biologist Charles Davis commenting that this research into extreme plant design is essential to understanding the interaction between parasites and hosts. He said that “plants are incredible chemists.” We agree that plants are incredible chemists, but only because the Master Chemist has fine-tuned plants and all of life to survive and thrive on this incredibly well-designed planet. God has given us plants to provide oxygen, food, and a wide range of medical products that enrich our lives.

In a previous post (December 4, 2021), we reported on the titan arum (Amorphophallus titanum), which is known as the “corpse flower.” It also produces the smell of a rotting corpse and attracts flies for pollination. Interestingly, the titan arum uses the same means for pollination, but it is not related to Rafflesia. Evolutionists would call that “convergent evolution,” but we call it evidence of a common Designer.

Messenger RNA in Plants

Have you ever thought about how plants know where, when, and how to grow? Research funded by the National Science Foundation found that plants have messages packaged into their RNA. They send messenger RNA (mRNA) from cell to cell to coordinate their growth. How do the mRNA molecules know where to go and how to get there? They have an escort to guide them.

This all looks pretty complicated, and it is. The escort for the mRNA is a protein called AtRRP44a. Without this escort to guide the messenger RNA between the cells, the cells can’t coordinate their growth, and the plant can’t develop properly. This cell-to-cell communication allows the plant to have all the information it needs to grow successfully in a changing environment.

Rigid walls surround plant cells, so how can the messenger RNA go from cell to cell? The mRNA, escorted by AtRRP44a proteins, can cross the barriers through tiny holes called plasmodesmata. The plasmodesmata are nanochannels that allow RNA and proteins, hormones, ions, and nutrients to pass from cell to cell.

Dr. David Jackson, who headed up this research at Cold Spring Harbor Laboratory in New York, says, “…plants are very sophisticated. We think of them just sitting in their environment, not moving, but they’re processing a lot of information. The different parts of the plants are talking to each other, sharing whether they have a pathogen attack or if they need some nutrients.”

Have you ever wondered how plants know when to shoot up in the spring, how to not shoot up in the fall, and how to handle infestations by insects and fungus? The creation of plants with this highly sophisticated communication system of messenger RNA and escort proteins is difficult to comprehend.

The more we understand of the creation, the more we see God’s wisdom and sophisticated handiwork. These design features are not accidents but the product of incredible intelligence and creativity.

The Contrast Between Forests and Cities

Genesis 1:11-12 describes Earth having three kinds of plants which most versions translate as grass (“deshe” in Hebrew), herbs (“eseb” in Hebrew, meaning a non-woody plant with seasonal foliage such as most vegetables), and fruit trees (“ets” bearing fruit “peri” in Hebrew). Genesis 2:9 tells us that “the Lord God made every tree that is pleasant to the sight, and good for food.” The first mention of cities in the Bible is in Genesis 11:1-9 with the Tower of Babel. Then in Genesis 13:12, Lot chooses to live “in the cities of the plain,” Sodom and Gomorrah. The Bible shows a contrast between forests and cities.

The habitat of early humans described in the first chapters of Genesis is very different from the cement-paved cities filled with massive structures that we see in the western world today. The construction of cement jungles has brought on an enormous number of social problems as well as pandemics and nutritional issues. As we see the contrast between forests and cities, we are slowly beginning to understand that God’s original design works best.

Archaeologists have a new airborne laser research tool called LIDAR (Light Detection and Ranging). It enables them to see through the canopy of vegetation, and they are discovering ancient cities hidden by the rainforests. Researchers are finding causeways, hydrological networks, massive structures, and elaborate ceremonial centers. They are seeing the remains of the Maya in South America, the Angkor in Cambodia, and an area called Kuk Swamp in New Guinea.

In these ancient cities, palm trees, Brazil nuts, sugar cane, bananas, and many tropical fruits were harvested from trees that surrounded dwellings. In addition, people grew small patches of maize and millet between the trees. Today, we are beginning to insert green spaces into our cities, and new varieties of plant products are showing up in our grocery stores.

Archaeologists have found evidence of millions of people living in cities in the Amazon basin, Africa, and Asia. The first attempt at farming in Britain was some 6,000 years ago, but in the Fertile Crescent, farming dates back to 11,000 years ago. The Fertile Crescent is the biblical location of the Garden of Eden, which brings us back to God’s original plan for human habitation.

A failure to properly use all the resources God has given us has brought pain, disease, and hunger throughout history. As we see the contrast between forests and cities, we come to appreciate the blessing of the resources God originally created.

Reference: “Rethinking the Jungle” by Matthew Symonds in Current World Archaeology Magazine (#110) for December 2021/January 2022. Symonds shows that the jungle can support massive human populations without all the ills of modern agriculture and city dwelling. His approach is evolutionary, and much of the article comes from a new book by Patrick Roberts titled Jungle: How Tropical Forests Shaped the World – and Us (Viking/Penguin 2021, ISBN – 978-0241472743).

An Overlooked Role of Birds and Mammals

Various data sources show massive evidence of climate change. The melting of the ice sheets, the warming of the Pacific Ocean, and the increase of weather anomalies affect all of us. Some of these changes have to do with flooding and the frequency of storms. Others affect our food supply where there is an overlooked role of birds and mammals.

While the effect on human activity is pretty dramatic, the natural changes in living things in the environment are usually less noticeable. The reason is that the design of life anticipates that climate will change from time to time, even if humans have no role in that change. If a plant species faces environmental change threatening its existence, it will disperse its seeds into a different place where the environment is more suitable.

The often overlooked role of birds and mammals is that they are the primary agents for seed dispersal. The National Science Foundation helped fund a study showing that more than half of all plant species rely on animals to disperse their seeds. The NSF website said, “Plants that rely on seed dispersers can face extinction if there are too few animals to move their seeds far enough to keep pace with changing conditions.”

One of the things that plant-eating dinosaurs did was to spread the seeds of the plants they ate. This means that pruning was not the only benefit of plant-eaters, but seed spreading was also significant. As the climate has changed in the past, animals have spread the seeds over a vast geographic area allowing the incredible diversity we see in plants today.

This kind of research has a variety of practical uses. It reminds us of the overlooked role of birds and mammals in dispersing seeds in the environment. The study showed a 60% reduction due to the loss of seed-spreading birds and mammals.

We see evidence of God’s wisdom in designing birds and mammals with a diet that allows spreading the seeds of the plants they eat. That design helps to moderate the effect of climate change. God told Adam and Eve to take care of the Garden (Genesis 2:15), and we need to understand our responsibility in that. The fact that creation’s design allows life to survive climate changes is a testimony to God’s wisdom.
