Design Is an Illusion – Not

Design Is an Illusion – Not
If you read our posts and publications regularly, you probably know that we are continually talking about design in the universe, on our planet, and especially in living things. We think that it is impossible to look at life and say that we see no design. However, some people can see the same things and say design is an illusion. They are willing to accept on faith that everything came into existence out of nothing and evolved by pure accident with no intelligence involved.

One person who refuses to see design in nature is a very well-known evolutionary biologist. Richard Dawkins has written several best-selling books that are supposed to be on the subject of biology. However, they are actually books on theology. The high point (or low point) of his books on theology is The God Delusion (Houghton Mifflin 2006). He travels the world giving lectures on theology, under the guise of biology.

Dawkins’ field of study is biology, not theology, so we take his pronouncements with a grain of salt. However, even Dawkins has to admit that his biological studies appear to show design. In his book The Blind Watchmaker he wrote, “Biology is the study of complicated things that give the appearance of having been designed for a purpose.” However, he then goes into theology by stating that design is an illusion and there is no designer. That means there is no ultimate purpose in life beyond day-to-day survival. In River Out of Eden Dawkins wrote, “The universe we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil and no good…”

No design, no purpose, no evil, and no good—that’s the way Dawkins describes the living things he has spent his life studying. Life, of course, includes human beings—you and I. If Dawkins is right, why should he study living things, or why should we? What is the purpose of using our purposeless lives to study purposeless things? Perhaps Dawkins has found his purpose in theology as he endeavors to convince everyone that there is no God.

As we think about this, we have to be amazed at how incredibly ironic the Dawkins delusion is. In the meantime, we will continue to admire the design we see in the world and pay homage to the Designer. Faced with the Dawkins challenge that design is an illusion, we choose to believe our eyes–and our common sense.

Justifying Animal Behavior in Humans

Bonobos - Justifying Animal Behavior in Humans
We have received several letters from people suggesting that sexual practices among animals show that humans are not unique in their moral choices but are merely acting out their animal heritage. Our supposed animal heritage can then be used for justifying animal behavior in humans.

We have read articles and news releases describing animal behavior including the pedophilia practices of bonobo apes, and recreational sex, rape, and homosexuality in monkeys. We have seen documentaries on the fact that many males in the animal kingdom kill the babies of their own species. The supposed reason for that is to push the mothers of those babies to become more quickly receptive to the sexual advances of the males.

It is a foolish argument to suggest that humans are just animals and that all human behavior is inherited and therefore we can’t condemn it. One PBS program recently said that the greatest threat to the babies of bears and lions was from the males of their own species. I am sure that very few atheists would maintain that human males should not be condemned for killing their offspring.

The other major point we would make is that sexual activity in animals is almost always a way of expressing dominance and control. The pedophilia practices of the bonobos produce extreme violence among the clan. Using sex to show dominance or to establish a pecking order among the group is a long way from the purpose of human homosexuality.

God created humans in His image. That means that dominance and control is not the only focus of our relationships. The “oneness” that God intended for sexual relationships (Genesis 2:24) is a long way from establishing who is going to control the group in which they live. The “agape” love which humans are capable of, goes far beyond sex. In John 17:24-26 Jesus spells out agape in terms of God’s love for His son. Animals are not capable of that kind of love.

When humans misuse sex or use sex only for physical pleasure, the result is always catastrophic. After Amnon raped Tamar (see 2 Samuel 13) he “hated her exceedingly.” That was the beginning of a long series of tragedies for the whole family. Justifying animal behavior in humans violates the uniqueness of humans and human relationships, just as it did for both Tamar and Amnon. Animal sexual activity does not produce what God intended in the marriage relationship.

California Wildfires Follow Up

California Wildfires Follow Up
Our printed journal for the fourth quarter of 2018 contained an article titled “Lessons From the Fire.” In it, we pointed out that the California wildfires in 2018 were the result of human mismanagement of the forest, and not some “act of God” as the media has sometimes reported. In the article, we gave three biblically-based lessons that we should have learned from the fire. You can read it HERE.

We have received responses from people who live in the fire area. Here is a recent email comment:

“I drive past the ruins from this fire when going to the doctor and have observed that houses are being rebuilt in the same location using the same materials. Nothing has been learned from the past experience. Besides this, lawyers are having a field day getting clients to sue the local utility company. One of them has had a half page ad in the local paper every day since the fire. It’s true that the company power lines were responsible for some of the fires…but not all of them.”

The fact is that the start of the fires was not the issue. The real problem was the biomass that provided fuel for the flames once they started. There has been almost no discussion in the media about managing the other forests in California that are tinderboxes waiting for a spark to repeat what happened this fall.

God didn’t cause the California wildfires, and He will not prevent catastrophe from resulting from human stupidity, mismanagement, and greed. God told Adam, “take care of the garden of Eden, dress it and keep it” (Genesis 2:15). The basis of that command surely applies to us today. It is up to us to take care of what God has loaned to us.

Programmed to Change

Colour Sergeant Butterfly - Programmed to Change
When I was a child, I was introduced to the metamorphosis of a caterpillar to a chrysalis to a beautiful butterfly. I decided to figure out how that change took place, so I cut open a chrysalis to see what was going on inside. Instead of catching the transformation in progress all I found was a capsule of black soup. Later when I asked biologists how the process took place, I realized that no one fully understood it. The caterpillar was programmed to change, but nobody could understand how.

What I did learn was that this process goes on in a wide variety of life forms. Frogs, sea urchins, flying wasps, and beetles are just a few examples of creatures programmed to change. The December 2018 issue of National Geographic features a wonderful article about the use of 3D models and micro-CT scanning of the process. These tools have given us a great deal of understanding of how this transformation occurs. The article identifies three stages of the change that happens as the caterpillar changes into a butterfly.

1. PROGRAMMED ACTIVATION. The caterpillar eats vegetation until it is full grown. As it does so, its hormones begin to shift with some parts of the caterpillar expanding and others becoming degenerate. The thoracic legs grow into legs that are good for grasping. Four wing buds on the caterpillar’s body begin to develop into wings, and the antennae become larger. The silk gland begins to degenerate to become the chrysalis. The proleg degenerates making the caterpillar more dependent on crawling. The mandible the caterpillar uses for chewing begins to degenerate making room for a tube for sipping nectar. The simple eye of the caterpillar which could only detect the presence or absence of light begins to change. All of this is programmed into the genetic makeup of the caterpillar.

2. TRANSFORMATION. As the prolegs degenerate, thoracic legs grow to adult size. Wings develop with full color from the four wing buds. The chewing mandibles morph into two halves that zip into pipes that make a straw-like proboscis. Simple eyes move forward closer to the brain and produce a compound eye which gives true vision.

3. EMERGENCE. The brain of the butterfly is almost completely rewired to meet flight requirements.  One thing that the butterfly seems to retain from its caterpillar stage is olfactory memories. It needs that to know where to produce the next generation of caterpillars. The butterfly sucks in air until its chrysalis breaks open. The butterfly flaps its wings for several hours to dry them and to circulate blood before flying off in search of a mate.

All of this happens in 15 to 21 days. The gut of the butterfly shifts from digesting plants to nectar in that short time. There are wonderful artistic drawings of all this in the article. The author summarizes his study by saying, “..the insect’s makeover is a programmed mix of destruction and growth. Certain cells die, and body parts atrophy. Meanwhile, other cells, in place since birth, rapidly expand in as little as two weeks, the adult emerges completely remodeled, capable of flight – and bent on finding a mate.”

We would add that no programming happens by chance. It takes intelligence to program a computer. The caterpillar programmed to change to a butterfly reflects the wisdom and intelligence of a great programmer superior to anything the software companies can offer.

Pallas’s Long-tongued Bat and Hummingbirds

Pallas's Long-tongued Bat
Most of us have seen hummingbirds hover over flowers or at our backyard feeders. Studies of hummingbirds show that they have a powerful downstroke and a recovery upstroke that twists part of their wing almost backward. The twist supplies about a fourth of the energy required to keep the bird in the air. The rest of the lifting energy comes from the downstroke. Because the hummingbirds have such a small mass, it doesn’t take a lot to keep them airborne. There is a bat known as Pallas’s long-tongued bat (Glossophaga soricina). It also sips nectar like the hummingbirds, but the bat is much larger.

Aerospace engineer and biologist David Lentink wanted to see how a more massive animal can accomplish hovering. His Ph.D. student Rivers Ingersol built a flight chamber with special sensors to study the hovering of hummingbirds and bats. He took it to Costa Rica and measured the hovering of 17 species of hummingbirds and three bats, including Pallas’s long-tongued bats.

Ingersol discovered that the upstroke of the nectar-sipping bats’ wings generated a little more energy than the upstroke of other bat wings. But the majority of the lift was generated by the powerful and deeply-angled downstroke. The result is that the bat’s very large wings provide the same hovering power per gram of body weight as the hummers wings. The authors of the study conclude that “supersizing can have its own kind of high-tech design elegance.”

Building a bigger wing that can withstand the stress of rapid beating to allow hovering is an engineering challenge. Proverbs 8 discusses the role of wisdom in all that God has created. Pallas’s long-tongued bat is a wonderful display of that wisdom.

Honeybee Clusters – How They Survive

Honeybee Clusters
Among the most interesting things to see in the natural world are honeybee clusters. When bees search for a new location, the queen will move to a tree branch or some other surface she can hang onto. The worker bees cluster around her making a large ball. Researchers have noticed that the ball of bees changes shape as various forces like wind or vibration are directed at it. The changing shape fine-tunes the cluster to resist the elements protecting the queen and the cluster as a whole. The question is how the bees know where and how to move to hold the ball together.

Researchers at Harvard University have found that the strain sensed by each bee is the answer. When a bee feels stress from the wind or some other external force, they will move to an area of greater strain. Many bees moving to protect the cluster flattens the cluster’s shape making it more resistant to the source of the stress. The bees are taking more strain on themselves for the good of the cluster.

In fundamental physics, we know that Young’s modulus is the ratio of stress to strain and every material has a value. Understanding the values is critical to engineering structures to prevent material failure leading to the collapse of the structure. Apparently, bees have a high Young’s modulus designed into their genetic makeup to allow the honeybee cluster to survive.

Researchers emphasize that our understanding of insect behavior is in its infant stage. As concerns grow over the loss of bees that are important pollinators, more research is of great importance. Our understanding of God’s designs in the natural world continues to grow. The complexity of even such simple things as honeybee clusters tells us we have a lot to learn. It also tells us much about God’s wisdom and engineering design.

Can’t Get That Song Out of My Head

Can't Get That Song Out of My Head -Yellowhammer Singing
Have you ever had a song stuck in your head? Sometimes we hear a song, and it seems to keep ringing in our brains for days. It may be a song we love. Sometimes it’s an annoying song that we can’t stand but can’t forget. Advertisers often use jingles in their commercials hoping that their little songs will keep haunting us until we buy their products. Whether good or bad, I can’t get that song out of my head.

I can be thankful that whatever the song is, it will eventually go away–and be replaced by another one. Imagine what it would be like if you had only one song for your whole life. More than that, imagine that your children and future descendants still had that same song. That could be the description of the life of a songbird.

We love to hear songbirds, and with a little effort, we can learn to identify different species of birds by their songs. That’s because, for the most part, each species has its unique song that it passes on from generation to generation.

Songbirds are born with a song stored in their brains. As the birds grow, they learn to match their vocal patterns to the song in their heads. Even if a baby bird never hears its parents sing, and although surrounded by the songs of other species, it will still learn to sing the song that its parents sang. There are a few species of birds that can imitate the songs of other birds, or even human voices and other sounds. Those birds are born with a different program built into their brains that gives evidence of a creative Designer of life.

When I can’t get that song out of my head, I can start singing or listening to a different song. Humans have that ability because the Designer has given us a creative capacity. That’s part of being created in the image of a creative God. But what if all people made their houses precisely the same way? Besides singing the songs of its parents, a bird will build only the same kind of nest its parents made. You would have to say that Someone also stored the nest-building instruction book in the bird’s brain.

Is it possible that an intelligent Designer drew up the nest plans and created the songs and placed them in the bird’s DNA? Generation after generation, the song and nest data are pre-programmed for the birds to follow. Remember that the One who drew the nest blueprints and wrote the songs and programmed them into the tiny brains of those birds is the One whose, “eye is on the sparrow” and furthermore, “I know He watches me.” (Matthew 10:29-31)

Ultimate Food Source

Ultimate Food Source - Antarctic Krill
One of the great necessities that a planet must have to support life is an ultimate food source that everything can eat. It must be highly nutritious, exist over a long time, and have very little waste. Modern oceanography has uncovered such a food source in an unlikely place. They found it in the frigid Antarctic ocean waters. The form of life is a small shrimp-like creature called Antarctic krill (Euphasia superba).

The amazing thing about these creatures is their abundance. Scientists found one swarm that covered several square miles and ranged in depth from 60 to 600 feet (12 to 180 m). They estimated the total weight of this one swarm is 10 million metric tons. That is equivalent to one-seventh of the entire planet’s weight of fish and shellfish caught in a whole year. It would amount to 98 pounds for every person in the United States.

Krill are rich in protein and have negligible bone and shell material. They consume microscopic animal and plant organisms as their primary food. Krill are near the bottom of the ocean food chain providing food directly or indirectly to everything in the ocean, including whales.

The Scripps Institution of Oceanography did the original studies of this particular swarm. Data from other oceanographic research ships show that krill swarms are common in the ocean. Since they can even be turned into food for humans, Antarctic krill seem to be God’s ultimate food source for all living things on this planet.

Leaf Designs to Preserve Trees

Leaf Designs to Preserve Trees
We live in a part of the world where there are many trees. We also experience heavy winds that frequently blow down human-made structures. It is interesting that healthy trees are almost never blown down. When you stop to think about it, you would expect trees to be major victims of high winds. That is not the case, and it is due to leaf designs to preserve trees.

To survive strong winds, trees need two things. The most obvious is structural support–strong, flexible branches, sturdy trunks, broad bases, and good root anchorage. A more subtle requirement is leaf designs to preserve trees. Leaves must have minimal wind drag. A fluid, such as air, flowing around an object generates drag. To minimize drag requires some streamlining to reduce the amount of friction between the fluid and the object. A highly streamlined object will usually be gently rounded upstream and elongated and pointed downstream.

For healthy trees, the leaves offer the most surface area and thus the most drag. Trees most commonly blow over when in full leaf, so leaf design is critical to the survival of the tree. Different trees have different design features, but all of them are designed to avoid destruction in a wind storm. American holly leaves have a method that involves the leaves being able to flatten themselves against each other. When the wind becomes strong, the leaves turn and lie flat significantly reducing the drag.

Tulip tree leaf design allows the leaves to roll up when the wind gets strong. The blade of the leaf points away from the stem. As the wind blows against the leaf, it forms a cone pointing upwind at the stem. The blade forms the broad area of the cone away from the wind direction. The higher the wind, the tighter the cone and the less the wind resistance. Black locust leaves similarly roll together to produce a cylinder.

Each of these designs depends on the properties of the leaf. If the leaves were too stiff, they could not assume the right geometry. The flexibility of their stems has to be high, and the surface of the leaf must be carefully designed and restricted. You can argue that natural selection does all designing and that given enough time it will select the proper shape. But remember that changes in climate mean you don’t have infinite time to apply the process.

God’s engineering wisdom gave us leaf designs to preserve trees. The leaf design allows the longest season for each tree. Sit in your backyard on a breezy day and watch what the leaves do to preserve that tree you prize so highly.

Hamburgers Without Beef

Is Hamburgers Without Beef in Your Future?
There has been a lot of hype about red meat and its potential damage to our health. The FDA held its first public hearing about growing meat in the laboratory instead of using cattle–or for that matter fish or birds. The challenge is to produce hamburgers without beef.

One process that scientists are experimenting with involves growing “cultured meat” in the laboratory from real animal cells. The other idea is to create “meat” from plants with the protein and taste of real beef hamburgers without beef. Beef production is the top emitter of greenhouse gases, and growing beef from cows emits over 100 times more greenhouse gases than plant material would emit to produce the same amount of meat. Patrick Brown of Impossible Foods in Redwood City, California says “Animals happened to be the technology that was available 10,000 years ago for making meat. We stuck with that technology, and it’s incredibly inefficient by any measure–and destructive”.

When Nicolas-Joseph Cugnot introduced the first combustion steam-powered vehicle in 1771, it offered significant advantages over the horse. In 1898 urban planners in New York were concerned about the 50,000 tons of horse excrement that 175,000 horses in New York City were producing every month. Ten years later Henry Ford introduced the Model T which eventually eliminated the problem. How long will it take for plant-produced beef to solve the environmental and health problems caused by the use of cows to produce food? The beef industry is huge in America, hamburgers without beef are likely to be available in Europe and Asia before they are accepted here.

Some people believe that Christians cannot eat manufactured meat on religious grounds. Even those who go back to the meat prohibitions of the Old Testament will find no support for forbidding plant-produced hamburgers. In Genesis 9:3, God told Noah that he could eat of any “green plant,” but the law placed massive restrictions on eating animal-based protein. In 1 Corinthians 8:8-13 and in Romans 14:1-5 Paul expressed concern over the influence of Christians who because of their freedom to eat anything, might pose a problem for those who don’t understand that food is not a religious issue. Romans 14:17 summarizes this by saying, “The kingdom of God is not about meat and drink; but righteousness and peace…” In 1 Corinthians 10:25-27 Paul tells Christian to eat whatever is set before them “asking no questions.”

The silly aspect of religious concerns about eating manufactured foods is that we already do it. Think of the list of manufactured foods that we eat now. They include artificially produced fruits and vegetables such as tangelos, and hybrid apples, corn, and tomatoes. Other food substances include margarine, soy milk, artificial sweeteners, butter spray, etc. We copy God’s design of the foods we eat to enlarge the food supply of the planet and avoid waste.

Food chemistry is highly complex, but the more we understand the creation, the closer we get to the Creator. Let us thank God that we don’t go to bed hungry. Also let us thank God He has given us the ability to meet the needs of the hungry as we understand how we can produce and use these new foods, including hamburgers without beef.
