Phalaropes Spinning for Food

Many times we see animal behavior that seems impossible to explain. We see an interesting example of that in wading shorebirds called phalaropes. These birds can get food that is too deep in the water for them to reach.

Instead of the typical methods used by shorebirds to capture their food, phalaropes take a different approach. They spin around and around in one place at the breakneck speed of one complete rotation a second. They kick seven to eight times on each spin and move their heads to where they can quickly snap up food. Researchers have found that these birds can detect prey, thrust and seize with their bills, transport and swallow the prey, and do it all in half-a-second.

Using high-speed photography, researchers found that the phalarope creates a vortex that is over three feet deep. The vortex acts as a miniature tornado bringing food up to where the bird can reach it. You could understand how one bird might learn this skill, but it seems to be genetically implanted as baby birds do the spinning even when they have had no contact with adult birds.

We see in phalaropes, as in most animals, that God has given them a genetically-based technique for acquiring food so they can survive.

Deforestation and Disease Pandemics

One of the interesting aspects of the story of Adam and Eve is the environment in which God placed them. Genesis 2:8 tells us that God planted a garden, and verse 9 tells us that He planted every tree that was pleasant and good for food. The Bible doesn’t say how long God took to plant the garden and what was involved in the garden’s growth. Verse 15 tells us that “God took the man and put him into the garden of Eden to dress it and to keep it.” After establishing the man’s environment, the Genesis account turns to man’s spiritual nature. But the planted garden with every tree is our focus here as we think about deforestation and disease.

The Bible describes the first humans as what anthropologists call gatherers. Agriculture was a long way off. The eating of animals isn’t even suggested until chapter 4 when Abel brings “the firstlings of his flock” as an offering to God. An article in Scientific American (June 2020, page 8) points out how modern agricultural methods have led to the three major highly infectious viruses since 2002 – SARS, EBOLA, and COVID-19.

Slashing and burning to create land for crops, such as palm oil, reduces biodiversity and puts humans in contact with wildlife that carry microbes able to kill us. Species that survive the clearing are more likely to host illnesses that can be transferred to humans. In addition to the three main viruses of our time, the Scientific American article mentions some other diseases have come from rain forest inhabitants – Zika, Nipah, malaria, cholera, and HIV.

Humans have brought on most of our major disease issues by allowing greed and “survival of the fittest” mentality to govern our decisions about how we use the environment. We waste between 30 and 40% of the food we produce. Poor agricultural techniques and mismanagement of water prevent efficient use of what God has given us. Deforestation and disease go together. Now we are contaminating our atmosphere and filling our lakes, rivers, and oceans with waste.

The title of the Scientific American article is “To Stop Pandemics, Stop Deforestation.” God gave us the “garden” and the tools to manage it. We can’t continue to mismanage it and not see more consequences such as pandemics, global warming, and diseases produced by our failure to do what God called us to do in the beginning.

Animal Viruses and Human Illness

The COVID-19 virus has been too lethal to ignore. This pandemic makes us realize that there are many viruses out there, and the current one is just the tip of the iceberg of what is possible. As early as AD 165 to 180, pandemics killed massive numbers of people. Smallpox killed 5 million, and bubonic plague killed 25 million on four different occasions starting in 541. Researchers today are attempting to catalog links between animal viruses and human illness. They estimate that there are probably 1.6 million animal viruses yet to be discovered in mammal and bird populations and that 827,000 of them could cause disease in humans.

Viruses are part of the natural world in which we live. They serve useful purposes in aiding animal digestion, reproduction, and elimination of wastes. The problem is that each animal has its own set of viruses suited for that animal’s diet and living conditions. If an animal’s virus jumps into another species with a different diet and living conditions, the results can be destructive. That is the connection between animal viruses and human illness. Most of the viruses we know about came into the human population from rodents, including rats, bats, birds, chimps, and mosquitos. Some have jumped through several animals such as bats giving the virus to cattle and camels, which gave it to humans.

The Old Testament laws had health restrictions, which made virus transmission less of a problem. People were also not in such proximity to one another or to animals that had destructive viruses. Living in very arid conditions reduced disease transmission, and the dietary laws worked against most virus transmission. When you read through Deuteronomy and Leviticus, you see elaborate precautions that we now understand had hygienic benefits to minimize viral transmission.

In the New Testament, many of these rules were continued. There was a prohibition against drinking blood, and the increased use of baking and boiling foods contributed to a low virus transmission rate. Moral rules that reduced the spread of disease included the elimination of polygamy and polyandry and the strong condemnation of prostitution. In time, the keeping of exotic pets and the acceptance of foods previously forbidden to Israel tended to thwart human attempts to fight disease.

God has given us the capacity to understand viruses and the connection between animal viruses and human illness. God has also given us the tools to control these virus issues. He has also given us hope for something better. Will we use the tools and techniques God gave us to stop the pandemics, or will we open our culture to more viral events in the future? Time will tell.

Difference Between Communication and Language

Sue Savage-Rumbaugh has made a career of studying bonobo apes. She would have us believe that there is no barrier between bonobos and humans. Her research raises the question of who we are as humans, and she would respond that we are just another animal. There are so many difficulties with this viewpoint that it is hard to know where to start. The most fundamental scientific problem is that there is a difference between communication and language.

Savage-Rumbaugh’s research is the main story in the July/August 2020 issue of Smithsonian magazine. She assumes that environment is not a factor in what distinguishes apes from humans, and she has lived with the bonobos in her research. A tool she uses in studying the bonobos is a “lexigram keyboard” with pictorial symbols corresponding to English words. One particular bonobo named Kanzi has used it to communicate with her. This ape could use some 660 English sentences functioning at a level higher than a two-and-a-half-year-old human child.

The difference between communication and language is an old issue. Aristotle wrote that animals could exchange information, but only humans could articulate what was just and unjust. The famous philosopher Rene’ Descartes in the 1600s, wrote that God had gifted human beings with souls, and, along with souls, language and consciousness. On this website and in our printed materials, we have talked about God’s design in animals that allows elaborate communication. Bees communicate by dancing information to other bees. Birds make sounds that carry meanings and warnings to other birds. The ultrasonic emissions of whales are elaborate communication tools.

Savage-Rumbaugh has shown that bonobos have a flexible capacity to communicate. However, she falls into the old trap of anthropomorphizing animal behavior – reading human interpretations into something an animal does. Statements such as, “She would look at me with a pleading expression on her face” is ascribing human interpretations to the ape’s facial expressions. The symbols on the keyboard are human symbols, and pigeons can learn to peck a particular symbol to get a desired result.

The Smithsonian article quotes one researcher as saying, “Work with Kanzi has always lived somewhere between rigorous science and social closeness and family life.” The difference between communication and language is a topic of hot debate. If you look up the word “language” you will see a significant variation in how different people define it. Humans have language that involves the meaning of symbols, the standards by which we measure behavior, and the values accepted by one’s peers.

The Bible deals with language, and God’s Spirit is involved with our language. When researchers have tried to humanize a chimpanzee by bringing it into their home, they do so with communication, but language is never a part of the process. Trying to turn an animal into a human being has disastrous results. We are created in the image of God, and language is a part of that image.

Chemical Warfare in the Plant World

We mentioned yesterday that plants use scents to attract friendly and helpful insects and animals. They also use fragrances to protect against unfriendly visitors. Seemingly passive plants have secret weapons against insect invasions. We call it chemical warfare in the plant world.

A good example is the lima bean. Spider mites attack lima bean plants, but other predatory mites eat spider mites. When spider mites attack a lima bean plant, it floods the area with a chemical signal that attracts the predatory mites. This chemical odor also causes other lima bean plants to emit the same chemical. When the spider mites are gone, the plants stop secreting the chemical.

Some plants, such as tobacco and corn, protect themselves from destructive caterpillars by sending off a signal to attract wasps. Research has shown that plants customize the signal to attract a particular species of wasp. The wasps can tell the difference between the chemical signal of plants attacked by tobacco budworms and corn earworms, and different chemicals attract a different wasp species. So far, cotton, corn, and beets have been shown to have different emissions as they call for protection.

We previously mentioned wasps that kill and eat the caterpillars of certain butterflies. In that instance, ants have a symbiotic relationship with the caterpillars to protect them from the wasps in exchange for food. The U. S. Department of Agriculture is looking to find ways to cause one insect to combat another. This research is necessary because it can help us find ways to protect crops.

Chemical warfare in the plant world shows that God has equipped plants to protect themselves against different insect scourges. Because of that, we can survive on a planet where insects hopelessly outnumber us. The design that the Creator put into living systems is truly amazing.

Plant Chemistry for Survival

Plants have a unique problem that animals don’t have. That problem is a lack of mobility. Since plants are unable to move, they manufacture chemical toxins to kill bacteria, alkaloids to ward off herbivores, and sweetness or color to draw in pollinators and animals that will disperse their seeds. They use plant chemistry for survival.

Crocus and gardenia flowers produce a chemical compound known as crocin. It gives the color to the gardenia’s red-orange fruit. Crocin is also the chemical that gives the stigmas of saffron flowers, commonly called “threads,” their bright hue. Researchers at the University of Buffalo have sequenced the genome of the gardenia and examined how it makes crocin. By duplicating those processes, they have produced crocin in the lab and made it available for use in medical and nutritional applications. Crocin has antioxidant properties and may help in the suppression of cancer cells. The plants use crocin to attract pollinators, and we use it for medical purposes.

Research shows that plants get the power to produce a whole arsenal of genetic tools to help them survive by a process called tandem gene duplication. Dr. Victor Albert, a co-author of a study published on BMC Biology, says that plants can duplicate some parts of their genetic toolkit and tinker with the functions.

Many of the processes and tools we have came from studying the design built into the living things around us. That is why the writer of Romans 1:20 says, “..the invisible things of God from the creation of the world are clearly seen, being understood by the things that are made…” The chemistry seen in the botanical world is an excellent demonstration of the wisdom of their design.

There is much more to God’s amazing design in the plant world. Tomorrow, we will bring you more on plant chemistry for survival.

Designed for a Purpose

On this website, we often talk about design in living things. Everyone sees design in the world around us. It’s impossible not to see design. Even the leading atheist biologist Richard Dawkins said that biology is the study of things that appear to be designed for a purpose. However, he believes they only appear to be designed because he knows that design requires a designer. The trick is to pretend that it is not design but merely a pattern produced by natural selection acting on random chance mutations.

Our study of design is not the ancient god-of-the-gaps concept where we say, “I don’t know how this happened, so there must be a god who did it.” Instead, we consider the evidence for the possibility of these “designs” happening by pure chance. Is chance or intelligence a better explanation for what we see in living things? Can the features we observe be explained more effectively by natural selection acting on random mutations; or by intelligent design? Which alternative has greater explanatory power and is, therefore, more plausible? Can you say with confidence that living things were not designed for a purpose?

Every day, we see machines and devices created by human intelligence. We marvel at the complexity of such things as computers, automobiles, or vehicles for space travel. The intricate design of living things, including humans, is far greater than any of those human-designed devices. Do we ever question whether the human inventions came together by accident? But some would say, “Those things are not alive, and therefore they can’t design themselves. Living things can change on their own through natural selection.”

That brings up the question of where did the first living thing come from? It came from non-living matter. How did that lifeless material assemble itself into something as complex as a living cell that could take in nourishment and reproduce? Where did the information in the DNA come from? Random text can’t assemble itself into intelligent language, and the DNA contains a language so complex that it took modern computers to decipher it. What intelligence wrote the code within the DNA of each plant and animal, giving them the ability to change and adapt to stay alive?

We see random patterns in clouds, or sand, or waves blown by the wind. We see patterns of sunlight on the forest floor as it shines through the tree leaves. Those things are random. Though they may be beautiful, they are not examples of design. When we see the biological systems working within a living animal or plant or study biomes and ecosystems working in harmony to make life possible, we observe more than a chance pattern. We are beholding something that was designed for a purpose by an intelligent Designer.

Bringing it closer to home—that means an intelligent Designer designed YOU for a purpose.

Why Did Dinosaurs Exist?

An interesting question we often hear is, “Why did dinosaurs exist?” We have pointed out in several articles and posts that none of the words used to describe the animals in Genesis 1 can reasonably describe a dinosaur. The same is true in Job and other scriptures that describe large animals. If we take Genesis 1, the animals described in that chapter are animals Moses knew, and their role was clearly defined.

We have suggested that the dinosaurs were a part of the preparation of the Earth for human habitation. “In the beginning God created the heaven and the earth” does not tell us how He did it or what processes and time were involved. Asking why did dinosaurs exist, leads to the question of whether there was a logical reason for an animal like brontosaurus to exist.

Science News (July 4 and 18, 2020) published an article about research on the lowland tapir (Tapirus terrestris), the largest mammal in South America. The Amazon Environmental Research Institute in Brazil refers to the tapir as the gardener of the forest. The rainforests would be biological deserts except for the actions of the tapir. This large mammal feeds on the seeds of about 300 plant species and defecates them in areas that would otherwise be barren. In modern times the tapir has been a primary factor in the recovery of burned-over areas. When Earth was a barren desert at the time of the dinosaurs, the problem would have been even more critical.

We suggest that the dinosaurs were the gardeners of the Jurassic and Cretaceous geological periods. A brontosaurus would produce massive amounts of dung filled with seeds. They would have kept a balance between plant growth and the re-seeding of plants. The enormous meat-eating dinosaurs were mostly carrion eaters that helped with cleanup and helped to control the populations of plant-eaters.

As we question why did dinosaurs exist, we see God’s wisdom in the process of creation. He provided a world that allows humans to have food and resources to use in daily life. At the same time, the design left a guide for modern humans to follow in locating and synthesizing these resources. We know where to find the minerals and fuels because we understand the process God used to put them there.

Animals Designed to Clean Up Biological Waste

One of the fascinating areas of scientific investigation is studying animals designed to clean up biological waste. This is especially true in mountainous regions where dry conditions and harsh terrain do not allow normal organic decomposition.

The lammergeier or bearded vulture (Gypaetus barbatus) is an example of such an animal. This large bird lives in scattered mountainous areas in Europe and Africa and across Asia, including Siberia and the Himalayas. It has a wingspan of ten feet (three meters). The main item on its menu is bones.

The World Atlas of Birds reports that this bird picks up the bones of animals that have died naturally or been killed by predators and carries them to high elevations. It then drops the bones onto the ground to smash them into smaller pieces. Lammergeiers do not eat just the bone marrow. They actually swallow large pieces of bone. To do this, they have an extremely elastic esophagus. Their stomach has a group of cells that secrete a highly concentrated acid, which is stronger than battery acid. It is strong enough to dissolve the calcium in the bones to liberate the protein and the fat. Amazingly the bird’s digestive enzymes are specially designed to survive a highly acidic environment and continue to function.

We need animals designed to clean up biological waste. Many animals are designed to survive in environments that are inhospitable to life. With special adaptations built into their bodies, they can do quite well. Trying to find ways that any one of these designs could occur by chance is challenging. Seeing designs in birds that require a large number of things to be changed simultaneously is an even greater challenge. Birds such as lammergeiers, woodpeckers, and penguins are great examples of the creative abilities of God.

Fish That Can Live Out of Water

Evolutionists often try to use fish that can live out of water to support various theories of the origins of living things. One example is a family of fish known as mudskippers (Oxudercinae).

Mudskippers can live as long as 2 ½ days out of water. They live along the shorelines in tidal pools where there is very little oxygen. They burrow into the mud when the tide goes out and stay there until the next incoming tide. Mudskippers inflate their mouth and the cavity around their gills with air. When the fish emerges from the mud, it deflates and immediately takes another gulp of air. Their mud burrows contain enough oxygen for the fish and its eggs to survive. This is a case where the fish modifies its environment to survive in a place where life would otherwise be impossible.

In Michigan, we have a fish called the bowfin (Amia calva) or popularly called dogfish. This species of fish shows up in some of the earliest rocks of the Earth. They have obviously been around for a long time, so sometimes they are called “living fossils.” In addition to gills, they have gas bladders with a small pneumatic duct that allows them to gulp air and survive for some time out of water.

Do these fish that can live out of water show a transition between aquatic and land animals? The short answer is “no.” They do show that living things were designed to adapt to changing environments and even to modify their environments for survival. The more science researches living things, the more we realize that God has designed animals and plants to make every ecosystem alive with life. It is up to us to take care of the environment as we marvel at God’s creative power and wisdom.
