Observing Fibonacci Day

Humans look for ways to celebrate certain days. We laugh at Groundhog Day and use Valentine’s Day for special human relationships. Some days have extensive significance, such as Thanksgiving, Christmas, or Veteran’s Day. We are now observing Fibonacci Day on November 23. Fibonacci Day is an unusual celebration of a remarkable mathematical sequence.

Fibonacci was an Italian mathematician who noticed in the year 1202 some interesting oddities about a particular sequence of numbers: 1,2,3,5,8,13,21,34,55, 89,144, 233. Notice that when you add any two sequential numbers, you get the next number. For example 5 + 8 = 13; 8 + 13 = 21; etc. If you divide two sequential numbers, you get .618034, which some mathematicians have called the “golden mean.”

Applying this Fibonacci sequence to architecture, you get a practical application. A rectangle using any two sequential numbers is aesthetically pleasing to human eyes. If you cut a square off any of these rectangles, you get another rectangle with the Fibonacci sequence. If you connect the corners of the squares in a series of Fibonacci rectangles, you get a spiral (see sketch).

An amazing thing about this is that there are an unlimited number of examples of Fibonacci spirals in the natural world. A small sampling includes:
*The spiral arms of galaxies curl in a Fibonacci spiral.
*The curl of a wave in the ocean fits the Fibonacci spiral.
*The snail shells curl in a Fibonacci curve.
*Elephant tusks curve in a Fibonacci spiral.
*The roots of human teeth curve in a Fibonacci spiral.
*Spider webs fit the Fibonacci spiral
*Keys on the piano are 5 black and 8 white, 13 in all, fitting the ratio.

*Musical chords producing pleasing sounds have the Fibonacci ratio.
*Bacteria growth curves fit the Fibonacci ratio.

There is no natural or evolutionary reason for the Fibonacci sequence. Notice it isn’t just in one discipline but in widely separated areas of study.

The Fibonacci Association publishes a magazine called the Fibonacci Quarterly, and people have written several books about the Fibonacci ratio. If you are observing Fibonacci Day, realize that this demonstrates God’s design in the creation. Chance does not produce a pattern across multiple disciplines like this.

COVID in Animals On the Rise

The COVID pandemic has taught us a lot. People need to be aware that COVID has been found in 32 different kinds of animals. A few domestic cases have had a strong effect on humans both economically and medically. Realize that this data is just the recorded cases, and the actual case numbers of COVID in animals may be far higher.

The most significant instances of COVID in animals have been in the American mink. The problem is that mink farms have large numbers of animals confined in small spaces, allowing the virus to spread quickly. The November 2022 issue of Scientific American reported 787 cases in minks. As a result, some mink farmers have had to destroy their entire stock to stop the disease from spreading. White-tailed deer are the second-highest wild animal group, with 467 reported cases of COVID.

Dogs and cats had the next highest numbers–353 cats and 225 dogs with reported COVID infections. There is great concern about these domestic animals since they are in constant contact with humans. Rounding out the domesticated animals that can carry and spread the virus are cows, hamsters, and ferrets.

The remaining cases in both the wild and in zoos include lions, tigers, gorillas, otters, beavers, lynxes, and hippopotamuses. These cases show that the virus is very active among mammals and will continue to spread unless animal vaccines are produced and used. Our domestication and use of wild animals means that new strains of COVID in animals will continue to arise. Humans can get the virus from animals as well as other humans, and we can also pass it back to animals.

Studying the origins of the disease and compiling a database of infected species will make it easier for scientists to learn how to protect against COVID and other virus infections. We humans are often our own worst enemies, but God has given us the wisdom and the tools we need to be good stewards of life on Earth.

Beavers Can Help Reduce a Climate Change Problem

People here in Michigan consider beavers a nuisance because they cut down trees and flood farmlands. Unfortunately, beavers cut down some beautiful shade trees on our property. However, beavers can help reduce a climate change problem.

A significant problem associated with the changing climate is the loss of water. Many reservoirs in the western United States are at extremely low levels, and some have completely dried up. Precipitation amounts have dropped while humans mismanage natural water storage.

Meanwhile, people have hunted and trapped beavers due to high prices for pelts and the flooding of farmland and private homes by the dams they built. The result is that water now floods downstream areas. Beavers reduce that problem by creating ponds that hold the water, so it runs off much more slowly. Besides reducing flooding, this also helps to minimize droughts. Studies funded by the National Science Foundation show that by live trapping and moving them upstream, beavers can help reduce a climate change problem.

God has provided ways to make climate change less damaging. For example, storing water in snow and glaciers helps mitigate the problem of water distribution. Additionally, beavers can reduce the problem by building dams that hold water back, providing relief from weather extremes.

God has given us the responsibility of managing what He has created. However, by creating pollution and mismanaging natural resources such as beavers, we have created problems we can no longer ignore. We can all participate in caring for the creation, and pleading ignorance won’t stop the damage.

Designing a Planet to Support Life

An interesting electronic game is one where you have access to a reservoir of materials to design a life-sustaining planet. Once you choose your materials and processes, the game computes how long life could survive on your planet. All the choices end up sterile, but the player with the longest survival time is the winner. Unfortunately, the limited number of variables causes all the options to eventually result in a lifeless globe because designing a planet to support life is a complex process.

As scientists examine systems that support life on Earth, they find multiple complex systems with some surprising agents that allow life to exist over the long haul. For example, we have written before about how many bird and mammal species spread seeds. Also, ants spread the seeds of more than 11,000 plant species. Without ants, the existence and abundance of many plant species could be impossible. A recent study has shown that other insects also spread seeds, allowing the enormous number of plant species on Earth.

Most plants have a compound called “herbivore induced plant volatiles” (HIPVs for short). A plant releases these HIPVs when caterpillars start eating its leaves. The HIPVs attract hungry predators that eat caterpillars. A recent study showed that agarwood (Aquilaria sinensis ), which is native to China, depends on hornets to spread its seeds.

Agarwood fruit produces HIPVs even though it is not assaulted by caterpillars. The agarwood HIPVs attract hornets which rush to capture the plant’s seeds. The hornets carry the seeds to their nests, where they eat the fleshy nutrient-rich structures called elaiosomes attached to the seeds. The hornets discard the seeds on the ground near their shaded nests. The seeds would dry out and die in the sun, but they germinate to produce new agarwood plants in the shade.

The Chinese people use agarwood for various purposes. However, the plant is listed as “vulnerable” because of habitat loss and the fact that local people eat the hornet larvae. Designing a planet to support life is a complex and challenging goal only God can do. Unfortunately, humans lack the wisdom to protect the life-sustaining system God has created for us.

The Design of Lobster Eyes

How do you design an optical system that enables an animal to see 2300 feet (700 m) below the ocean’s surface? That question is similar to the problem that astronomers face as they look into low light levels in areas of space around black holes. The answer came from a detailed study of the design of lobster eyes, and scientists at the Goddard Space Flight Center have successfully copied it.

The human eye works by refraction, bending light by using rounded lenses. The lobster’s eyes work by reflection. Each eye of the lobster is packed with 10,000 square-shaped tubes lined with a flat, reflective surface that acts like a mirror. These mirrors direct incoming light to the retina, where tiny cells trap the light and focus it onto a layer of photoreceptors. This allows the lobster to have a full 180-degree view compared to the 120-degree view of human eyes. It also enables them to detect motion in low-light conditions.

In 1992, researchers from Columbia University built a device that mimics the design of lobster eyes, but the technology required 15 years to build a device for use in space missions. Studies using the lobster eye device have shown how the solar wind interacts with Earth’s magnetic field. In addition, newer models are opening the door to detecting faint X-rays from distant galaxies.

The design of lobster eyes is another of many design features in animal life that scientists have copied, leading to new discoveries. A visual system this complex is not the product of blind accidents. We see the handiwork of God everywhere we look in the natural world. The same God who designed the lobster’s eyes has given us the design for how we should live, and it’s written in His Word, the Bible. We would be wise to follow it.

Nanofibrils of Spider Silk

Would you like to see a material that is stronger than steel and can stretch ten times more than Kevlar? If so, look at a spider web and marvel at the design of the microscopic nanofibrils of spider silk.

Researchers at William and Mary University, funded by the National Science Foundation, used atomic force microscopy and nuclear magnetic resonance to examine the molecular structure of spider silk as never before. The nanofibrils of spider silk are fibers with diameters in the nanometer range, 10,000 times smaller than a human hair. Spiders generate them using proteins.

The scientists found seven layers of structural hierarchy in the spider silk. At a molecular level, they saw six distinct protein substructures making up the nanofibrils of spider silk, giving it incredible strength and resilience. They hope their research will lead to the development of high-performance synthetic fibers.

The nanofibril structures are so complex that understanding how they give spider silk its properties takes a great deal of time and special equipment. We have discussed spider web materials previously, but this new research shows that it is even more incredible than we realized. Hannes Schniepp, the director of the study, said, “Right now, we’re innovating and discovering in tiny steps, but there’s the larger goal of fully understanding the structure of spider silk. This study solves a piece of the puzzle and takes us closer to the larger dream of one day making materials like nature and, in doing so, create a more sustainable world.”

Studying God’s design in nature has led to an incredible number of things that make our lives more comfortable and enable us to solve some of the problems we face. Romans 1:20 tells us we can know there is a God through the things He has made. One of those things is the nanofibrils of spider silk.

Diving Bell Spiders Breathing Underwater

In freshwater lakes, ponds, and rivers in Europe and Asia, a spider spends virtually its entire life below water, catching prey, mating, laying eggs, resting, and overwintering. Called diving bell spiders or simply water spiders (Argyroneta aquatica), they are the only spiders that breathe air underwater.

Diving bell spiders have a very dense layer of hydrophobic (water-repelling) hairs on their abdomen and legs that they use to hold a bubble of air. They create a “diving bell” by spinning an underwater web to hold the air bubble. The web is made of silk and a specially-designed and unknown protein-based hydrogel. They spin these sheets between submerged water plants and inflate them with the air held by the spider’s hydrophobic hairs. The silk is waterproof but porous enough to allow gas exchange with the surrounding water. There is a net diffusion of oxygen into the bell and a net diffusion of carbon dioxide out.

Nitrogen escapes from the bell as this process continues, so the bubble size decreases, and the spider has to bring new air in periodically to retain the bubble’s size. However, this system is so efficient that they may not have to add air for more than a day. By being underwater their whole life, diving bell spiders have only frogs and fish as their predators. They play an ecological role in the water body by eating aquatic crustaceans and insects such as mosquito larvae.

God has designed many different systems to allow balance in nature. When humans upset the balance, we create problems. The more we study the less visited areas of planet Earth, the more examples we find of unique life forms. We also find ways of copying God’s designs to create new materials and new ways to improve our living conditions.

Marvels of Engineering in Nature

In the creation, we see many patterns that are marvels of engineering. You might not think that shape of a structure is vital to the survival of living things, but it is. As we look more and more carefully at the design of natural things, the evidence shows us that they are not products of blind chance but designed for a purpose.

Considering materials science, the honeycomb design is an excellent place to start. The magnificent honeycomb design uses hexagons stacked into a lattice. Does that make a difference? The answer is a very strong “yes.” The honeycomb must hold a very heavy and dense liquid requiring careful weight distribution. If you designed a honeycomb in a rectangle or triangle pattern, the weight would be on the bottom of the holder, causing it to collapse. In the hexagon design, the weight is distributed in three directions, reducing stress on the bottom.

We see this hexagonal pattern in many areas in the natural world, such as columnar basalt in the structure called Devil’s Tower in Wyoming. As the original molten mass cooled, it contracted, and the structure’s shape relieved the gravity forces.

Using a scanning electron microscope, scientists studied common sea urchins (Paracentrotus lividus). They found that the point where their spines attach, called tubercules, have a mathematical pattern of polygons called a Voronoi pattern. The tubercules must withstand strong forces, and the Voronoi pattern provides strength in a lightweight skeletal structure. This pattern gives maximum strength to organic structures that must withstand significant stresses.

Researchers say this design allows sea urchins to withstand predator attacks and environmental stresses. Besides bees and sea urchins, dragonflies also benefit from Voronoi patterns. The scientists studying these marvels of engineering hope that they will “inspire new developments in materials science, aerospace, architecture, and construction.” We can learn much by studying the designs God has used in creation.

Ants Are Essential for Life on Earth

“Go to the ant, you sluggard; consider her ways and be wise.” That biblical injunction from Proverbs 6:6 was written to motivate the lazy and idle person to get busy. The fact is that ants are among the most important life forms God created, and scientists are finding more evidence that ants are essential for life on Earth.

Over 20 quadrillion ants are living on this planet. That’s 20, followed by 15 zeroes. When you add up the total weight of the carbon in those 20 quadrillion ants, you get about 12 million tons. That is more than the combined mass of wild birds and mammals, or about 20% of the total weight of all humans.

Scientists have studied and named more than 15,700 species and subspecies of ants, and their research is adding more to that number each year. Ant chemistry is vital to the existence of all kinds of life. For example, in my army survival training, they taught us to eat ants.

Many people think of ants as pests that serve no purpose but to irritate us and bring problems into our homes. By contrast, research has shown that ants provide a massive service to humans, and we could not survive on planet Earth without them. For example, consider these roles that ants play:

Ants aerate the soil, disperse the seeds of many plants, and break down organic material, enriching the soil and enhancing plant growth.
Ants create a habitat for other animals and provide an essential part of the food chain for mammals and birds. Also, many birds rely on ants to flush out their prey.
Ants are predators that keep populations of other insects in check. They are more effective than pesticides in helping farmers produce food. Ants eat many worms, caterpillars, and insects that eat our crops and leave no destructive chemicals as pesticides do.

Like much of what God created for our benefit, ants help us in many ways we overlook. Managing God’s gifts requires protecting life forms, including ants. Ants are essential for life on Earth. Remembering the verse from Proverbs, we need to “consider the ant” in more ways than one.

Cannibalism in Animals and Human Cannibalism

Many things separate humans from all other animal life on Earth. One difference involves cannibalism. Scientific research has shown the extent of cannibalism in animals. In the wild, there are countless examples of animals eating their own offspring, the offspring of others, or even a mate. Cannibalism is an easy way to get food, and among predators, nearly all animals who are carnivores sometimes practice cannibalism.

Population density is a significant factor leading to cannibalism in animals. Also, a sick animal unable to get food in the usual way will frequently resort to cannibalism. Some animals will eat other animals’ young to avoid their offspring having to compete for food. Animals such as bears and lions will kill and eat their offspring to stimulate the females into early estrus. Many reproductive issues are involved in animal cannibalism.

Why do some tribal groups practice human cannibalism? The answer is almost never because of food shortages which often lead to cannibalism in animals. However, there is one biblical case where hunger led to cannibalism. Second Kings 6:24-29 tells about a war that caused famine in Samaria, leading two women to agree that they would boil their two sons and eat them. The first woman’s son was cooked and eaten, but the second woman hid her son. The response of the King when he hears of this shows that it was not an accepted practice.

There are cases where people in extreme duress have eaten human flesh. However, human cannibalism practiced in jungle civilizations involves religious reasons, not the desire for humans as food. Instead, they would eat an enemy’s brain to gain their knowledge or their body to gain their strength.

It isn’t just our culture that finds human cannibalism repulsive. Christianity teaches that the human body is the temple of the Holy Spirit (1 Corinthians 3:16). Our Christian heritage has taught us that human life and the temple in which it resides are special and sacred.

Jesus told His followers to love their enemies. The Greek word “love” here is “agape,” which means “to consider of enormous value.” Our enemies are still unique with eternal souls, making them of incredible worth. This is far from the atheist philosophy of “survival of the fittest.” Killing a human is contrary to all that Jesus uniquely taught. As society drifts away from Christ and His teachings, spiritual cannibalism takes over, leading to war, suffering, and perhaps even physical cannibalism.
