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.

Creativity, Worship, and Thankfulness

Creativity, Worship, and Thankfulness
Three the things which separate humans from our animal friends are creativity, worship, and thankfulness. Humans, created in the image of God, display that image in our own creativity. We express creativity in various artistic and productive ways. One important area of human creativity is music. Birds sing, but all individuals of any species of bird sing the same song, and they have for as long as we have known that species. They are singing the song they were programmed to sing. The only exceptions are a few birds that imitate various sounds or imitate the songs of other birds. Imitation is not creativity. Humans sing and play, many different styles of music, and we are constantly creating new songs. We even combine worship with our creativity in music as we sing to honor God. Music moves us, excites us, and touches us deeply, making it a natural outlet for worship.

Thankfulness is another area that separates us from the animals. A couple of years ago, my wife and I were leaving a sandwich shop where we ate lunch. An elderly woman with a smile on her face came up to our car window holding a sandwich. I rolled down the window to see what she wanted, and she said, “Are you the ones who paid for my sandwich?” She said the employee in the store told her that a person ahead of her had paid, so she didn’t owe anything. I told her that I was glad for her, but we were not the ones who had done this generous act. As she went away, it was evident that the small kindness had made her day, but she was disappointed that she didn’t get to thank her benefactor.

There is something about humans that makes us want to express gratitude. Our pets are loyal to us because we feed them, and they get excited when they see us open the food container. But only humans are motivated to express true gratitude. We often show thankfulness toward each other, but our greatest debt of gratitude is to God. G. K. Chesterton once wrote, “the worst moment for an atheist is when he is really thankful and has nobody to thank.” One evidence of God’s existence is that not only does He give us many good things, but He also has given us the desire and ability to say, “Thank you.”

Creativity, worship, and thankfulness are human traits. I am thankful for the creative ability God has given us. I am thankful for the ability to use that creativity in art, music, and worship. I am also thankful for the ability to express gratitude to God.

Abraham Had Camels

Abraham Had Camels
It’s the case of the missing camels. One argument that biblical skeptics keep resurrecting is the claim that there were no camels in ancient Israel. In Genesis 24 Abraham’s servant took ten camels and went to find a wife for his son Isaac. The charge is that there were no camels in the Promised Land at that time so this account is in error. We want to know if it is true that Abraham had camels.

Camels are mentioned 22 times in Genesis and are mentioned again in Exodus 9:3, Leviticus 11:4, 1 Samuel 15:3, 1 Kings 10:2 and 2 Kings 8:9 as well as other passages. In modern times famed archaeologist William F. Albright claimed that there were no camels in the Holy Land until the 10th century B.C. National Geographic repeated that claim claim in 2014.

Dr. Mark Chavalas in the November/December 2018 issue of Biblical Archaeology Review makes it likely that Abraham had camels and the biblical account is not in error. He gives archaeological evidence that there were camels all around the Holy Land as early as the 4th millennium B.C. Here are five of the pieces of evidence Chavalas gives:

1) In the 4th millennium B.C., a bactrian camel (one with two humps) is portrayed in artwork in Eastern Iran.
2) In the 3rd millennium B.C., a dromedary (with one hump) appears on a plaque from modern day Iraq.
3) Camel skeletal remains from the 3rd millennium have been found in Iran.
4) Camel remains from 2400 B.C. were found in the Sumerian city of Shuruppak.
5) A Babylonian document from the 18th century B.C. contains the line “the milk of the camel is sweet.”

Abraham and his family came from Mesopotamia (Genesis 12) and moved to the land God promised to him. Migrating to this new land, Abraham, who was rich in livestock, would have brought his animals with him. (See Genesis 13:2.) So it seems evident that Abraham had camels. The attempts of skeptics to declare the Bible anachronistic is simply a case of letting prejudice override a reasonable search for evidence.

Where Did the Water Go After Noah’s Flood?

Where Did the Water Go After Noah's Flood?
Perhaps the most argued event in the Old Testament is the flood of Noah described in Genesis. This week we have been examining some of the questions people ask. Today we will look at the question, “Where did the water go after Noah’s flood?”

If the flood covered the whole Earth so that the highest mountain was under water by 15 cubits (Genesis 7:19-20), what happened to all that water? Genesis 8:1-3 says that “God made a wind to pass over the Earth” and stopped the fountains of the deep and the windows of heaven. That indicates three methods of removing the water. If the fountains of the deep involved underground springs that gushed massive amounts of water, that water could be removed by flowing back into the caverns from which it came. If “the windows of heaven” indicates an extraterrestrial source, it is difficult to suggest any significant return. High winds which the Bible mentions would maximize evaporation, but there are some other factors to consider.

It is important to point out that nowhere in the Bible is there an indication that the waters were level. We will discuss the extent of the flood in our next post, but the known earth at the time of this event was a limited area. At the Straits of Gibraltar, there is a normal fault with the downthrown side to the west. At the base of that fault is a large waterfall gouge. The Glomar Challenger Oceanographic Research Vessel has documented what appears to be an opening of the Straits with the whole Atlantic Ocean having access to the Mediterranean Sea at a time in the past, which was a desert before the flood. It is reasonable to propose a model where hydrostatic pressure could drive water up the western shore of the Mediterranean which is of course where the biblical story takes place.

While this is speculative, it does show that a limited flood to the known world at the time is possible. The water could merely return to normal static levels after the event. There are several other models based on recent evidence that assist in explaining the question of where the water came from and answering the question of where did the water go after Noah’s flood. Very important to this question is, “What was the extent of the flood?” We will examine that question tomorrow.

How Could All Those Animals Fit in Noah’s Ark?

How Could All those Animals Fit in Noah's Ark?
Perhaps the most argued event in the Old Testament is the flood of Noah described in Genesis. For the past two days, we have been examining some of the questions people ask. Today we will look at the question, “How could all those animals fit in Noah’s ark?”

The Bible gives the dimensions of the ark, and it indeed was huge, especially for that time. How do you get the 25 million or so species of animals on Earth today into that ship? The answer is that you couldn’t.

Genesis 6:20 lists the same groups that are described in Genesis 1. Those are (1) fowl, (2) cattle, (3) “creeping things,” and (4) fish. We pointed out in our lessons on evolution that the word “kind” in Hebrew is not the same as “species” in modern scientific terms. The word “kind” is the Hebrew word “min,” and the Bible tells us in both the Old and New Testaments that there are four kinds: the flesh of fish, the flesh of birds, the flesh of beasts, and the flesh of man. First Corinthians 15:39 identifies these four and Genesis 1 identifies them as well. The same groupings are used in Genesis 6 to describe what Noah took on the ark.

The Hebrew word “remes” is rendered as “creeping thing” in some translations of the Bible. “Sherets” is also translated creeping thing (see Leviticus 11). “Remes” was an animal the Jews could eat, but “sherets” was not. “Remes” clearly refers to goats and sheep – animals that could be eaten by the Jews. But “sherets” refers to things like snakes and lizards which they could not eat.

So how could all those animals fit in Noah’s ark? The point of all this is that Noah didn’t take two poodles, two cockapoos, two German shepherds, etc. He took two dog-like animals. Similarly, he took two bovines, not the dozens of varieties that exist today. There are over 100 varieties of chickens, but he took two of that group. In short, Noah’s ark would have had enough room, and the evolutionary change that has taken place since has given us the variety we have today.

Learn from the Animals

Learn from the Animals
We are frequently astounded by what animals can do. As science seeks solutions to problems such as having enough food, knowing how to avoid disasters, and solving medical problems, we frequently see the answers in the designed features of living things. There are many things we can learn from the animals.

How can we have enough food to feed everyone on this planet? One way is to take advantage of animals with high reproductive capacity. A female mackerel, for example, lays about 500,000 eggs at one time. We have relied on animals like cattle which have one offspring at a time, are environmentally unfriendly, and require massive energy to sustain. Many fish, arthropods and mollusks can reproduce massive numbers of offspring, need very little energy input, and give off little or no environmental hazards. Some of them even remove environmentally unfriendly materials.

Can we improve our vision and perhaps restore sight to people who are blind? Studies of the common dragonfly have shown that each eye has 30,000 lenses. Our one lens is limited as to what we can see. The way images are transmitted to the brain in animals allows multiple transmissions. We are learning from insects and chameleons how the brain can reconstruct a useful image from many separate images. A chameleon can move its eyes in different directions, and its brain can interpret the direction and identification of what each eye is seeing independently.

How can we make stronger materials? Beaver’s teeth are so sharp that Native Americans used them as knife blades. The structure of the tooth enamel in the beaver and how the teeth maintain their sharpness is an area where materials science researchers can learn from the animals.

Can we make better drones? Researchers are interested in how high-frequency wing beats can allow better control of flight. Tiny flies known as midges beat their wings over 1000 times a second – twice as fast as mosquitoes. We can even learn from the animals that are almost too small to see.

Examples like these challenge those who would attribute animal design to chance processes and survival of the fittest. The design engineering in the animal world suggests wisdom beyond that of humans. In Proverbs 8:5,22,35 wisdom speaks, “O you simple ones understand wisdom and you foolish ones, have an understanding heart. The Lord possessed me (wisdom) in the beginning of His way, before His works of old. For whoever finds me finds life and shall obtain the favor of the Lord.” Let us be wise as we copy the wise designs of the Creator.

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.

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.
