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.

The Size of the Cosmos

We have often mentioned NASA’s Astronomy Picture of the Day (APOD). Their March 16, 2022, post showed the above diagram of the OBSERVABLE universe. The emphasis on the word observable is because astronomers have realized that what we can see is only part of the creation. Our technology allows us to appreciate the size of the cosmos. When you look into space with today’s most powerful telescopes, you can see far beyond our Milky Way galaxy.

We can observe that there are billions of galaxies with different shapes, and each contains billions of stars. However, visible light is limited. Just as the light from a lightbulb appears less bright as you move further away from it, visible radiation from distant objects becomes dimmer the farther away they are. As a result, science has developed new instruments to see radiation other than visible light, such as Xrays and microwaves. In addition, we now have devices that can detect neutrinos and gravitational waves from objects still farther away.

Everything we can detect operates by the same physical laws that govern our own tiny part of space. So any suggestion that there could be universes with different physical laws and physical constants is pure speculation.

The more we learn about the size of the cosmos as we use improved instruments, the more obvious it becomes that the creation is too vast for us to comprehend. The cosmos speaks of design, power, and creative expression beyond what our technology can perceive.

The NASA website reveals higher dimensions, and the size of the cosmos speaks to us of a God beyond our comprehension. In the words of Psalms 19:1, “The heavens declare the glory of God and the skies show his handiwork.”

How Fish Navigate

A question that has bothered researchers for many years is how fish navigate. Fish move from one place to another, swimming around obstacles or locating food sources with no obvious way to know how to get to their objective. For example, we live on the edge of a river and have watched fish find their way around brush piles, even when the brush is moved by flooding.

Biologist Shachar Givon of Ben-Gurion University of the Negev in Israel conducted an ingenious experiment to learn how fish navigate. She constructed a fish-operated vehicle for a goldfish to drive. The vehicle consisted of a square fish tank fastened to a chassis with four multidirectional wheels. A downward-facing camera was connected to a computer algorithm which prompted the wheels to move the vehicle in the direction the fish was swimming. The six goldfish in the experiment navigated around obstacles and avoided dead ends. After one or two runs, they became proficient in reaching their goals. The researchers suggest understanding how fish navigate in unfamiliar territory, such as the terrestrial world, may help humans navigate in unfamiliar environments such as the zero gravity of space.

We can learn from the way God has designed survival methods in the natural world. In this case, we learn from an animal as primitive as a goldfish. The natural world is filled with examples of God’s design, and how fish navigate is just one of many systems we are just beginning to understand and may use as models to shape the future.

Creation of Heaven and Earth

As scientists find more and more evidence, the picture of creation becomes clearer. That is not to say that science has the entire creation of heaven and Earth figured out. However, studies have allowed us to see what was done, even if we don’t understand and will never in this life understand how it was done.

Science has identified four fundamental forces involved in creation. They are the electromagnetic force, the weak nuclear force, the strong nuclear force, and the gravitational force. These forces work on particles that science has observed or particles for which science has found evidence but has not observed. For example, photons are responsible for electromagnetism. Particles called gluons are responsible for nuclear forces, with eight gluons causing the strong nuclear force and three gluons causing the weak nuclear force.

The recently discovered particle called the Higgs boson gives mass to the force particles and controls their behavior. Physicists are studying how that happens and looking for a particle that causes the gravitational force. As research continues, science strongly suggests that those forces began as a single force. Our standard rules of physics cannot deal with this concept, and the time during which the forces originated is called the “Planck era.” The creation of heaven and Earth is not a simple process, and science is trying to understand it.

The so-called “standard model” of particle physics has so much supporting evidence that most physicists accept it as a starting point to understanding the process of creation. Some scientists have developed an approach called “string theory” to understand what took place in the Planck era. The mathematics of string theory forces us to believe that creation has come about from dimensions higher than our own. A prominent string theory called “bulk” has creation originating in an 11-dimensional arena. We live in a three-dimensional world with time as a fourth-dimensional quantity. The idea of 11 dimensions is beyond our comprehension. We can describe it mathematically, but we cannot visualize it.

The Bible summarizes the creation of heaven and Earth by simply indicating that an Intelligence in a far higher dimension than our own created time, space, and the physical world in which we exist. “In the beginning, God created the heaven and the earth” accurately describes what our research and observations tell us.

In summary, there was a beginning often described as the “big bang.” At that beginning, there was Planck time when our laws of physics did not apply. The creation event was caused by “Elohim,” an intelligence outside of space/time who operates in dimensions outside of our physical universe. The creation included the matter/energy from which everything is made and the three-dimensional space, “shamayim,” translated “heaven” in your Bible. It also included the planet we call home, “erets” in Hebrew, created from that matter/energy. The more we know of the creation, the more we know of the Creator.

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.

Our Sun Is Just Right

Scientific discoveries continue to show that our Sun is just right. It has the just-right size and just-right temperature, and it’s the just-right distance from our planet to make advanced life possible.

Add to those things the fact that the type of radiation our Sun emits is just what we need to survive. We have often talked about Earth’s magnetic field and how it protects us from some of the Sun’s harmful radiation. That fact shows the fine-tuning of our planet for life, and we don’t know of any other star so precisely-designed for life as our Sun.

The Sun has magnetic fields also, stretching far out into its atmosphere. However, those fields are not as stable as Earth’s magnetic field. The magnetic lines of force move like seaweed swaying in underwater gardens, but much slower. They carry energy from the Sun’s surface up into the corona, a bubble of plasma surrounding the Sun.

Some scientists think that the energy conveyed by the moving magnetic force fields might explain why the corona is hotter than the Sun’s surface. The surface is almost 10,000 degrees F (5,500 degrees C), but flares in the corona can reach millions of degrees. Although scientists have studied the Sun for years, they still don’t understand many things about it.

One thing we can know for sure is the fact that our Sun is just right can either be a fantastic coincidence or the wisdom of God’s design. We believe this is another evidence of design.

Much to Learn from the Animals

Animals have much to teach us. We have learned many things by studying animal anatomy and behavior and made numerous advances in medicine through animal studies. For example, principles of flight, the use of sonar, robotics, and improved adhesives have all been aided by studying animals. But one thing is for sure is that we still have much to learn from the animals.

Conversely, animals also learn from humans. That is especially true of mammals and birds, which can develop special relationships with humans. Dogs were domesticated from their wild ancestors thousands of years ago and have lived side-by-side with humans ever since. They learn from us, and they help us as we help them. Dogs assist people with vision problems and other illnesses. They provide valuable help to police and rescue workers.

You may have noticed that yawning can be contagious. When a person sees another person yawning, they tend to yawn also. Try this test. While your dog is watching, start yawning. Dogs often yawn after they see a human yawn, and they are more likely to yawn in response to their owner rather than a stranger.

God commanded us to have dominion over the animals (Genesis 1:28), and He gave mammals and birds the ability to relate to humans uniquely. If we pay attention, we have much to learn from the animals. In Job 12:7-10, Job said:

“But ask the animals, and they will instruct you;
ask the birds of the sky, and they will tell you.
Or speak to the earth, and it will instruct you;
let the fish of the sea inform you.
Which of all these does not know
that the hand of the Lord has done this?”

Job knew that the animals have much to tell us about the wisdom of God’s design for His creatures. Then in Job chapter 38:39 to 39:30, God uses descriptions of ten mammals and birds to show Job and his friends that they have a lot to learn. In Matthew 6:25-, Jesus told His followers that the birds can teach us a lesson about not worrying. In this time of chaos, war, and inflation, that’s a lesson we all need. Yes, we still have much to learn from the animals.
