Methane and Life on Other Planets

Astronomers are constantly looking for signs of life on other planets or moons. One of the potential clues they seek is methane, a hydrocarbon gas consisting of one carbon atom and four hydrogen atoms. It is classified as a “greenhouse gas” because it can trap heat on Earth’s surface resulting in “global warming.” It’s a more effective greenhouse gas than the much-discussed carbon dioxide. Methane is produced by organic decomposition and in the digestion process of ruminants such as cows and other animals. Scientists seek to learn more about a possible connection between methane and life on other planets.

Since living things create methane, scientists regard it as a potential “biosignature” indicating life on an astronomical body. For that reason, astronomers are searching for methane on planetary bodies. News reports have sometimes gone overboard with stories about methane and life on other planets. However, not all methane is created biologically. Volcanic eruptions can release methane gas, and even asteroid impacts can add methane to a planet’s atmosphere. So how can scientists tell if the methane is a sign of life on a body far out in space?

For one thing, gasses from a volcano would contain not only methane but also carbon monoxide. The biological creation of methane would consume carbon monoxide. When examining the gasses in a planet’s atmosphere, a large amount of BOTH methane and carbon monoxide would probably indicate that the methane was not a biosignature. Methane alone would be a more likely indicator of the possibility of life.

However, an abundance of methane without carbon monoxide would not prove the existence of life on a planet. As we have said before, many factors are required to make a planet suitable for any kind of life, especially advanced life. NASA’s James Webb telescope, launched in December, is still working to reach full functionality. When it does, a significant part of its purpose will be to look for methane in the atmosphere of exoplanets.

When results indicate that the Webb telescope has detected methane on a planet, news reporters may sensationalize the facts to suggest more than they deserve. Reputable scientists are more cautious in their predictions about methane and life on other planets. Nevertheless, we are excited about the possibility of learning more about the universe with the new Webb space telescope.

As we have said before, the Bible doesn’t tell us if there is life on any other object in space. If there is, we believe that God put it there. We are not afraid of scientific investigation because the more we learn about the creation, the more we stand in awe of the Creator.

Return of the Lyrid Meteor Shower

In late April each year, we see the return of the Lyrid meteor shower. It may not be the most spectacular meteor shower of the year, but I find it easier to observe. That’s because, in our part of the world, it comes at a time when the weather is mild enough to sit outside and watch (unlike the Geminids in December) and before mosquitoes become a problem (as with the August Perseids shown in the picture).

This year, the return of the Lyrid meteor shower is from April 14-30, with the peak on the night of April 22. Typically, the Lyrids display five to 20 meteors per hour at the peak, although, in some years, the number has been higher. Written records of the Lyrid meteor shower go back 2700 years when Chinese astronomers made note of it in 687 B.C. A Korean account from A.D.1136 says that “many stars flew from the northeast.”

If you see the Lyrid meteor shower, you will not be looking at falling stars, although you may get that impression. Instead, you will see tiny fragments of Comet Thatcher (officially C/1861 G1), discovered in 1861 by amateur astronomer A.E. Thatcher. That year was the last time the comet flew by our planet at 31.1 million miles (50.1 million km). Its next return to our vicinity will be sometime around the year 2280. Meanwhile, Earth’s orbit around the Sun causes us to pass through debris the comet left behind. So we see those fragments as they burn up from the effect of atmospheric friction.

We live in an orderly universe on a planet positioned to allow observation and study of the cosmos. Our planet is designed with an atmosphere and magnetic field to protect us from comet debris, meteorites, cosmic rays, and solar wind. If you have the opportunity to observe the return of the Lyrid meteor shower, use it as a time to thank the Creator for allowing us to live in the just-right time on a just-right planet in a just-right location in the universe.

Learning About Lepidopterans

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.

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

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

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.

Birds Navigate Across Oceans Using Quantum Effects

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.”

Magnetosphere Display Protecting Life on Earth

As the Sun approaches an eleven-year maximum of its magnetic cycle, solar flares and eruptions occur with increasing frequency and violence. That means the Sun is blasting out a massive cloud of fast-moving electrons, protons, and ions in all directions. To see the magnetosphere display this creates on Earth, go to apod.nasa.gov for March 22, 2022. There you will see what NASA calls “A Whale of an Aurora over Swedish Forest.”

The cloud of particles from the Sun would cause huge damage to life if it reached us unobstructed by Earth’s magnetic field and atmosphere. Earth’s magnetosphere deflects the charged particles coming toward us from the Sun. As Earth’s magnetic field moves the particles toward the poles, they hit molecules in our atmosphere, causing them to glow in a magnetosphere display that we call an auroral corona.

Most people in the higher latitudes of North America can go outside late at night and away from the city lights and see the aurora borealis or “northern lights.” Here in Michigan, the glow in the north was yellow and orange. In a northern city like Östersund, Sweden, the aurora was blue-green and high in the sky. The APOD picture may look like a whale to some, but I think it looks like an eagle. The color of the aurora depends on what elements are being hit by the solar emissions. The green is from oxygen, but orange and red come from hydrogen higher up in the atmosphere.

Earth’s magnetic field is essential as a shield to prevent radiation damage to all life. Scientists don’t fully understand what causes the magnetic field, but it is just right to allow life on this planet. Life would have to be underground for protection on planets with no magnetic field. When God created Earth, He gave it a magnetic field of just the right strength and geographic distribution to allow life to exist. This is another great testimony to the wisdom built into the creation process that formed our planet.

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.
