Learning About Lepidopterans

Learning About Lepidopterans - Monarch

One of the joys of life is the ability we all have to learn beyond school or college. Learning often happens when we contact someone who knows a lot about a subject we have never studied. For example, we recently visited the Marine Discovery Center in New Smyrna Beach, Florida, where we met specialists in butterflies and moths. So naturally, we were interested in learning about lepidopterans.

The order Lepidoptera includes butterflies and moths, and we learned that there are 2932 species of these insects in Florida. Studies have revealed incredible details about these creatures’ surprising complexity and design. The word “lepidoptera” means “scale wings,” and these creatures have microscopic scales on their wings. They have four wings – a pair in front and a pair in the back. Their bodies have three parts, a head, a thorax, and an abdomen with three pairs of jointed legs attached to the thorax.

Butterflies and moths taste with their feet, which means when they land on something, they immediately know whether it is food or not. These creatures breathe through tiny valves on the sides of their abdomen called spiracles, and they eat through a long tube called a proboscis. Butterflies are active during the day, and moths are active at night, with very few exceptions. Coming out of their heads between their eyes are antennae. In butterflies, the antennae are club-shaped, and in moths, they taper to a point. When a moth attaches to a surface, sensitive cells detect moisture, temperature, and exposure to the wind and rain.

Butterfly antennae have cells sensitive to the pollen of whatever plant its caterpillars need to survive. Each butterfly has a particular sensitivity to a specific plant or group of plants. For example, monarch butterflies are sensitive to milkweed. Farmers know which butterflies produce caterpillars that eat certain crops. In the natural world, the caterpillars of moths and butterflies are food for many larger creatures. When humans eradicate those predators, we upset the balance, causing problems for humans. Learning about lepidopterans and the environment is essential for understanding how to maintain balance. God did not design butterflies and moths to be destructive, but when we mismanage the environment, the result is a problem for humans raising crops.

The complexity of butterflies and moths is impressive. They have their larval ability to eat plants and produce silk to make a cocoon and morph into adults with the beautiful colors and designs of wing scales. Learning to control the destructive nature of caterpillars requires an understanding of the complexity of these remarkable creatures. Without the help of mature insects as pollinators, many other plants would suffer. Learning about lepidopterans shows us God’s excellent design of life.

In the Shadow of NASA

In the Shadow of NASA

The John F. Kennedy Space Center in Florida gets a lot of attention from the media. However, most people probably are not aware that attached to the Space Center in the shadow of NASA is the Canaveral National Seashore/Merritt Island National Wildlife Refuge. It has 69,000 acres of marsh left undeveloped and managed by the National Park Service. Researchers have identified 1045 plant species and 310 bird species in the shadow of NASA.

A dozen species of wildlife that are federally listed as endangered live there, including sea turtles, West Indian manatees, wood storks, eastern indigo snakes, and Florida scrub jays. In addition, there are the usual animals found in Florida, including land tortoises, otters, armadillos, and a wild assortment of crabs, insects, oysters, clams, and shrimp.

We had the pleasure of visiting this refuge the second week of April in 2022. It was interesting to watch hundreds of birds wading through the marsh, eating crabs and shrimp. We also saw mullet jumping as they were chased by larger fish and alligators basking in the Sun and then looking up to see a rocket being prepared to lift astronauts to the space station.

The refuge is a barrier island with sand dunes covered with various plants, including numerous palm trees and ancient oaks covered with Spanish moss and palmetto and sea oats. The National Park Service has built wooden walkways to control human traffic, allowing a natural environment to function within sight of the Kennedy Space Center in the shadow of NASA.

Just north of this area is New Smyrna Beach with its towering resorts, massive numbers of tourist attractions, and where people can drive vehicles on the beach. That area is essentially a biological desert with some gulls and pelicans and various sparrows, vultures, and blackbirds, but nothing like what we see in the wildlife refuge. The primary vegetation is a variety of human-introduced plants decorating the resorts. As you drive through the area, you see the trunks of dead palm trees everywhere but very little wildlife. Meanwhile, construction continues on more resorts and tourist complexes.

What happens when a hurricane hits this area? In the wildlife refuge, the answer is almost nothing. The vegetation holds the dunes and prevents the destruction of the plants and wildlife that depends on them. We all know about the collapse of the resort tower in this area, which tragically killed several people. No human structure is free from the elements. The human-introduced plants are generally wiped out in a hurricane and have to be replanted. Human attempts to control the area are at the mercy of natural processes. As the climate warms and water levels rise, more human-made structures will be destroyed, but what God constructed will survive. The refuge will change, and the wildlife and plant life will adapt, but it will do quite well left alone.

It was interesting to see the challenges facing the park service in the refuge. Roads don’t do well, and wooden structures have to be replaced. Meanwhile, the natural world functions smoothly and efficiently with an abundance of residential and migratory life. As humans try to control parts of nature, we constantly need to rebuild and replace. “And God said, “Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit … and God saw that it was good” (Genesis 1:11-12). You can see how good it is when you visit an area not corrupted by human ignorance, greed, and selfishness.

The Mighty Seahorse Threatened

The Mighty Seahorse Threatened

“The mighty seahorse” suggests a massive stallion galloping across the ocean’s waves. The reality is that these amazing fish range from 5⁄8 inch to 14 inches (1.5 to 35.5 cm), and they are threatened.

There are 46 identified species of seahorses, and the scientific classification is Hippocampus from the ancient Greek for ‘horse” and “sea monster.” This fish has a head like a horse and eyes that function independently and can rotate like a chameleon’s. They have a pouch like a kangaroo and a prehensile tail like a monkey. Instead of scales, their skin is covered with boney plates, spikes, and lacy skin extensions. They swim in a vertical posture using their dorsal fin for power while steering with their pectoral fins. They anchor themselves using the prehensile tail to grab onto a fixed object.

The reproductive system of the seahorse family is unlike any other group of animals. The male and female connect face to face with their tails entwining, and the female impregnates the male by depositing massive numbers of eggs in his pouch. Then, several weeks later, the males eject up to a thousand baby seahorses who will drift with the current, eventually settling down on seagrass or coral or any fixed object on the seafloor.

Seahorses eat smaller forms of sea life, including copepods, shrimp, and fish larvae. They are themselves part of the food chain eaten by larger fish. Commercial fishing operations catch 76 million seahorses a year, and human exploitation has endangered these animals.

Human understanding of all the agents of change and balance in the oceans is very limited. The role of the seahorse in the functioning of a healthy ocean has only recently become understood. The ocean system has a complex influence on life on the land. As we learn more, the complexity speaks of a design that makes chance an unlikely cause. God’s design of life on Earth is clearly seen through what has been made (Romans 1:20). The mighty seahorse is an excellent demonstration of that design.

Jonah’s Icefish and Animals of the Cold

Animals of the Cold include Jonah's Icefish and Ooligans

Deep-sea biologists from Germany accidentally discovered a massive colony of icefish nests under the ice in Antarctica’s Weddell Sea. The fish known as Jonah’s icefish have formed a colony the researchers estimate to contain 60 million nests 500 meters below the sea ice. The animals of the cold always amaze us.

Jonah’s icefish are nesting fish that carve out circular nests with rocky centers on the seafloor, where they lay over 1,000 eggs. Other ocean and freshwater fish species form nests, including bluegills that nest in the lakes of the midwestern United States. However, bluegill breeding colonies are limited to a few hundred individuals, not millions. Like bluegills that feed on small aquatic life and are food for larger fish, Jonah’s icefish play an essential role as food for the Weddell seals, and they feed on the abundant plankton in the Antarctic waters. 

When it comes to animals of the cold, Jonah’s icefish are like the ooligan (eulachon) fish of Alaskan waters in that their blood is full of antifreeze compounds. Ooligans have so much oil in their bodies that if you dry the fish and put a wick in its mouth, it will burn like a candle. In Alaska, a nickname for the ooligan is the “candlefish.”

Many animals are specially designed to live in very cold conditions. For example, one of the books in our children’s book collection is titled Animals of the Cold, written by Charlsey Ford. As well as the ooligan, that book discusses the musk ox, ice worms, and the Kermode bear. All of these animals are specially designed to live in the extreme cold. 

We see God’s design in every ecological system on our planet. Each time we find a new example, we are amazed at God’s creative design of life. Romans 1:19-22 reminds us that “We can know there is a God through the things He has made.” Jonah’s icefish is another excellent example of that truth.

The Purpose of Beauty

 The Purpose of Beauty - Sunset

Humans are obsessed with beauty. We try to make ourselves more beautiful with clothing and cosmetics. We seek to create beauty in music and art, and we continually long for something even more beautiful. But, what is the purpose of beauty, and how can we explain excessive beauty in nature? That is what we have called “the problem of beauty,” which we have discussed all this week.

Beauty is not to provide protection or to solve problems. The purpose of beauty is to bring joy, peace, and meaning to life. However, as we seek beauty, we long for something even more beautiful. We strive to create it, and we desire to find it in people and in nature.

The prophet Isaiah in a vision, saw God’s throne room where one seraph cried out, “Holy, holy, holy is the Lord of hosts, the whole earth is full of His glory” (Isaiah 6:3). God’s glory is displayed in the beauty we see on this planet. The curse of sin has marred that beauty, but it still peaks through. It reminds us of the Creator of “every good and perfect gift” (James 1:17). Theologian N.T. Wright asked the question that we all face at some time, “If the earth is full of God’s glory, why is it also so full of pain and anguish and screaming and despair?” That is what we call “the problem of pain.” I think we can see a glimpse of the answer in the purpose of beauty.

I suggest that humans appreciate and desire beauty because God created us in His image.
God creates beauty in the world around us to give us a sample of what is possible. When we see beauty, we long for more because we always find imperfections in the beauty we see here. Beautiful peacocks die. Colorful fall leaves turn brown and fall to the ground. The beauty of a sunset is fleeting. We long for more. We want to know what more God has in store for us.

The apostle John saw a vision of what God has waiting for those who accept His gift of eternal life. In Revelation chapters 21 and 22, he struggled to describe it in terms of the familiar, such as gold, pearls, and jewels, but he knew those words were inadequate. Perhaps the purpose of beauty in the world around us is to show us a glimpse of the glory of God’s beauty. We long for the revelation of the pure beauty of God’s kingdom. As we struggle to answer the problem of pain, perhaps the answer is before our eyes. The problem of beauty is only a hint, a clue, a sample of the ultimate beauty. I can’t wait to see the real thing.

Designed with Purpose and Beauty

Designed with Purpose and Beauty

Charles Darwin published his book On the Origin of Species in 1859, and Ernst Haeckel published drawings of embryos in his book The Natural History of Creation in 1868. Haeckel intended his somewhat inaccurate drawings to support Darwin’s theory by showing that embryo development reflects evolutionary development. As we said in yesterday’s post, those who reject the idea of a creator God try to explain what appears to be designed with purpose and beauty by saying it has no purpose and no designer. Beauty in living things can be a problem, or it can be a blessing, depending on whether you accept or reject the Designer of life.

Physicist and Nobel laureate Steven Weinberg is an atheist who rejects belief in God because of the problem of pain, which we can summarize as: “Why would an all-powerful and loving God allow pain and suffering?” Weinberg explains his view in his book Dreams of a Final Theory. However, he can’t explain the problem of why living things appear to be designed with purpose and beauty. He made the understatement of the century when he wrote, “I have to admit that sometimes nature seems more beautiful than strictly necessary.”

Evolutionary biologist and atheist Richard Dawkins, writing in his book Climbing Mount Improbable, told about a time when he was driving through the countryside with his six-year-old daughter. The girl was excited about seeing “pretty” wildflowers. Dawkins asked his daughter what she thought was the purpose of wildflowers. She replied, “To make the world pretty, and to help the bees make honey for us.” Dawkins said he was sorry that he “had to tell her that it wasn’t true.” According to Dawkins, biology is the study of things that appear to be designed for a purpose, but his atheism forces him to argue that there is no purpose.

The living world around us shows many examples of the problem of beauty. Various species sing songs and perform dances that go beyond what survival would require. Gibbons sing duets, and birds of paradise display their beauty with song and dance. Bower birds go to excess extremes to create works of art. The peacock’s beautiful tail is extravagant from a survival perspective. These animal attributes seem inefficient and not a method to adapt to the environment. They certainly go beyond survival of the fittest to what David Rothenberg, a philosopher at the New Jersey Institute of Technology, calls “survival of the beautiful.”

Is it possible that the excessive beauty of living things is merely an accident, or is life designed with purpose and beauty? What is beauty, and why do we care? We will conclude this discussion tomorrow.

Beauty in Nature

Beauty in Nature - Peacock
Peacock with Tail Spread

For the past two days, we have talked about beauty in nature and how it often seems to defy the evolutionary principle of survival of the fittest. Darwinists refer to “emergent order” as the process of living things coming into being without any design or intelligent guidance. Instead, they say it was accomplished by a set of simple rules laid out originally by Charles Darwin and refined into what is now known as Neo-Darwinism.

In his 1859 book On the Origin of Species, Darwin presented his principle of natural selection. However, he realized that natural selection acting on random mutations couldn’t explain the “selection” method used in all cases. Moreover, he was troubled by the excess beauty in nature. He saw unnecessary frills and flourish, which he could not explain by natural selection. A year after that book was published, his frustration caused him to write, “The sight of a feather in a peacock’s tail, whenever I gaze at it makes me sick.”

To cover those cases where natural selection can’t explain the beauty in nature, he introduced “sexual selection” in his 1871 book The Descent of Man, and Selection Related to Sex. Sexual selection involves the beauty often seen in male birds in general and peacocks in particular. According to Darwin’s sexual selection theory, the reason for the beauty of the peacock’s tail is that the peahens prefer such gaudy but impractical decorations. The same principle applies to many other species, such as bower birds or birds of paradise, where the males display striking colors or impressive actions to attract a mate.

German zoologist and eugenicist Ernst Haeckel was also an artist. He popularized Darwin through his artwork published in several books. His drawings depict the beauty he saw in even one-celled animals called Radiolaria, and he attributed the beauty to natural selection and mathematical principles. Haeckel was so enamored by Darwin’s hypothesis that he went out of his way to promote it in books of drawings.

Haeckel’s drawings sometimes showed his bias for Darwinism. For example, in The Natural History of Creation (published in German in 1868 and later in English), he displayed drawings that compared human embryos with embryos of various animals, suggesting that the development of those embryos repeats the path of evolution. However, he manipulated his illustrations to prove his point. Other scientists later pointed out the flaws, and his dishonesty discredited his scientific credentials.

However, the books of Haeckel’s drawings were best sellers in their day, and they are still selling even today. Nevertheless, those drawings did not prove design without a designer. We have called the question of how excessive beauty in nature could have evolved by natural selection “the problem of beauty.” Yesterday, we said that we prefer to call it the blessing of beauty—a blessing from God. However, atheists do not see it as a gift from the Creator, and they try to explain it away as accidental. They suggest that what appears to be designed for a purpose has no purpose and no designer. We will look at that tomorrow.

The Blessing of Beauty

The Blessing of Beauty -Nightingale Song
Nightingale Singing

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

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.

Birds Navigate Across Oceans Using Quantum Effects

Birds Navigate Across Oceans Using Quantum Effects - Bar-Tailed Godwit
Bar-Tailed Godwit

Over the years, we have spoken several times about the migration of birds as an example of God’s design in the creation. The Bar-tailed Godwit seems to be the champion of long-distance travel flying, traveling 7,450 miles (12,000 km) nonstop across the Pacific Ocean from Alaska to New Zealand. Many other bird species make similar long-distance journeys. The question we wonder about is how birds navigate across oceans thousands of miles with no landmarks. How do they know when to make the journey, and how do they manage the energy requirements of such a long flight.

Modern research has shown migrating birds have a compass that relies on quantum effects built into their eyes. These quantum effects use something called “radical pairs” that form photochemically to allow them to see the Earth’s magnetic field lines. Earth’s magnetic field is very weak, especially in equatorial areas. So any normal effect from the magnetic field would not have enough strength to contribute to navigation, but birds navigate across oceans and over the equator.

Retinal cells in the bird’s eye contain proteins called cryptochromes that contain a molecule called flavin adenine dinucleotide (FAD). Tryptophan amino acid stabilizes the FAD, so the molecules are electrically neutral. When a photon of blue light reaches the FAD, a quantum release of electrons makes a radical pair. The electron spin of the radical pair is so sensitive that the Earth’s magnetic field influences it. The bird’s brain detects the quantum changes allowing it to know its flight direction.

This is a simplified explanation of a very complex process by which birds navigate across oceans. Researchers Peter J. Hore and Henrik Mouritsen wrote, “When you next see a small songbird, pause for a moment to consider that it might recently have flown thousands of kilometers, navigating with great skill using a brain weighing no more than a gram. The fact that quantum spin dynamics may have played a crucial part in its journey only compounds the awe and wonder with which we should regard these extraordinary creatures.” We would add to that statement “…and the God who designed them, giving them this amazing ability.”
