Zoopharmacognosy Animal Doctors

Zoopharmacognosy Animal Doctors Zoopharmacognosy is a word you don’t see every day. It’s actually a combination of three Greek words which mean “animal” (zoo), “drug” (pharma), and “knowing” (gnosy). It refers to animals using plants, soils, insects, or drugs to solve specific medical problems. It is animals (not humans) medicating themselves. Mammals, birds, and even insects use zoopharmacognosy to cure medical problems, and sometimes to prevent them. Here are a few examples.

It is fairly common to see a sick dog or cat eating grass to induce vomiting.

Sick chimpanzees swallow bitter leaves of Aspilia, a plant that contains an anti-parasitic chemical. The leaves are covered with bristles and bitter tasting so the chimps roll up the leaves and swallow them whole like we might take a pill.

Others chimps and bonobos with diarrhea will split open the stem of an Aframomum plant and suck the bitter juice. The juice contains chemicals which kill parasites which cause diarrhea.

Spider monkeys in Brazil have been seen eating seed pods from a tree known as monkey ear or elephant ear (Enterolobium cyclocarpum) during mating season. The fruit contains progesterone which promotes female fertility.

Brown bears make a paste from the chewed roots of osha (Ligusticum porteri) mixed with saliva and rub it into their fur to repel insects and soothe the bites. The plant contains coumarins which repel fleas and ticks.

To get rid of lice, many songbirds with put ants on their feathers or even roll in an anthill. The ants secrete formic acid, which kills feather lice.

Ants infected with Beauveria bassiana, a soil fungus, will eat harmful substances that are antifungal.

Many kinds of animals will eat dirt to absorb toxins, to combat parasites, or as an antacid. Sometimes they eat dirt to supplement minerals that are missing in their diet.

Pregnant elephants will chew the leaves of a specific tree in the Boraginaceae family to induce labor. Kenyan women make tea from those leaves to help with childbirth. In many cases, people have learned medicines and tonics from animals.

There are many more examples of zoopharmacognosy in which animals act as their own doctors. How did animals get this knowledge? It seems to be instinctive, not learned. Perhaps this instinct was put within the genetic code of these animals by their Creator.

California Poppies Thrive

California Poppies ThriveThe past twelve months have been a time that most native Californians will never forget. After several years of drought, the entire state was affected by massive forest fires. When the fires were finally out, it seemed that everything would get back to normal, but then the rains started. Between the heavy snow and the unusually heavy rains, massive flooding became an issue. Without vegetation to stop the runoff, gloom and doom predictors were having a field day. The future looked bad, especially for southern California, but then came the California poppies.

I recently got a letter from a friend of mine who lives in southern California. The letter included pictures of what a few months ago was ugly, dark-colored, barren rock. The new images were ablaze with color. The California poppies withstood the fire because their seeds are not combustible and germinate faster in the conditions the fires produced. The seeds are also shaped in such a way that they don’t wash out even in heavy rain. With no competition, no predation to destroy the young plants, the poppies grew and bloomed like crazy.

Norma Privitt writing in the July/August/September 2019 issue of Power for Today described it this way:

“What a year this has been for California poppies! Abundant rain has unleashed God’s glorious array of orange flowers over all the barren hills. Even the limitations of TV do not restrict the obvious explosion of color. We traveled to view the poppies in previous years when their glory was only a smidgen of this year’s, but so many have made this year’s pilgrimage their cars line both sides of the roads, and finally, shuttle buses have had to be arranged. It almost seems symbolic that the plant that will anchor the soil and allow the land to begin to recover is a plant that blooms with brilliant orange drawing attention to God’s provision, even when human greed and abuse cause pain.”

Through California poppies, God has provided a way to bring beauty and hope even when things look dark and bleak.

Saguaro Desert Old-Timers

Saguaro Desert Old-TimersThe saguaro (pronounced suh-wah-roh) cactus is found only in the Sonoran Desert areas of southern Arizona, northern Mexico, and a small area of southeast California. We call them saguaro desert old-timers for a good reason. Saguaros grow very slowly as a single stem for perhaps 75 years before developing arms. Plants with five arms may be 200 years old.

Saguaro flowers bloom at night from April to June. They close by noon the next day, never to open again. Saguaro flowers can only be fertilized by cross-pollination so there must be a creature to carry pollen from one plant to another. Because the flowers bloom at night, bats are the pollinators. They drink the nectar and transfer pollen from plant to plant.

A successfully pollinated flower will produce a green, oval-shaped fruit with bright red pulp. Many desert creatures eat the fruit and aid the saguaros by spreading their seeds. Only a small percentage of the seeds will ever germinate, but that’s okay because each flower produces as many as 4000 seeds.

Not only do the saguaros have a symbiotic relationship with the bats which consume their nectar and the many creatures who consume its fruit, but it also provides shelter for many desert animals. Saguaros become apartment houses for birds, lizards, desert rodents, and reptiles, as well as a whole entourage of insects.

Saguaros are remarkably well-designed for life in a dry climate. The outside of the plant has pleats like an accordion. The pleats allow expansion for storing large quantities of water when the rains come. As with other cacti, the saguaro has needles rather than leaves to reduce the loss of moisture by transpiration.

Saguaro desert old-timers are designed in a marvelous way to live in the harsh conditions of the desert while providing food and shelter for various desert creatures. They are another indication of a Master Designer of life.

Beautiful Tulips in History and Culture

Beautiful Tulips in History and CultureTheir vibrantly colored blossoms are symbolic of spring. Tulips are part of the lily family (Liliaceae) and exist in many different species. They flower in the spring and die back in summer when the life is stored in an underground bulb until the next spring. Beautiful tulips are an excellent example of the beauty designed into this planet.

Tulips are known for their bold colors and attractive shape. Most varieties are almost perfectly symmetrical. The blooms have three petals and three sepals, but the tulip appears to have six petals because the sepals are large and generally the same color as the petals. You can find tulips in almost any color from white to black, but the bright and sunny colors are the most popular.

Without a doubt, beautiful tulips have a rich and interesting history. They originally grew wild in temperate areas from southern Europe to central Asia. They were first cultivated in Asia around the tenth century. Diplomats who visited the Ottoman Empire in the sixteenth century brought them back to Europe where they became hugely popular.

The tulip obsession began with Flemish botanist Carolus Clusius in 1594. He was the first person to identify “broken tulips,” which is a virus infection that causes impressive streaks in the petals. He would go on to create many different color variations of the flower. His amazing tulips led to a period from 1634 to 1637 called “tulip mania” when enthusiasm for the flower created an economic frenzy. Tulips quickly became the most expensive flowers in the world. At the peak of tulip mania, some bulbs were selling for ten times more than the annual income of a skilled worker. People even used tulip bulbs as currency. Artists of the Dutch Golden Age, including Rembrandt, depicted tulips in their paintings.

Today, the tulip is the national flower of Turkey and Afghanistan, but the most prolific producer of tulips is the Netherlands. There are annual tulip festivals around the world including the Netherlands, England, Switzerland, Canada, and even Australia, where the spring bloom occurs in September and October. Several locations in the United States have tulip festivals, including Holland, Michigan, which is near where we live.

It’s interesting how tulips could have such an impact on economics, culture, and history. God gave us beautiful tulips, and human intelligence has modified them to develop a variety of colors and patterns. If human intelligence could do that, think how much more intelligence was required to create the living plant with the genetic code that made it all possible.

Petoskey Stone Dilemma

Petoskey Stone TilesEvery part of the United States has rocks, plants, and animals that are unique to that area. Certain plants grow in abundance in various locations. In Arizona the saguaro cactus is abundant. California is home for giant redwood trees. Indiana has tulip trees. Many states have adopted an official flower, tree, bird, fossil, or rock. In Michigan, since 1965 our state rock has been the Petoskey stone.

The name comes from the city of Petoskey which got its name from an Ottawa Indian legend. Thanks to the glaciers that swept down from the north scooping up rocks and depositing them, Petoskey stones are found all over the state. When I took my earth science students to the local gravel pit, we would discover Petoskey stones mixed in with the gravel. A local jeweler would show the kids how beautiful jewelry could be made from those stones.

The Petoskey stone is a petrified tropical coral with the scientific name Hexagonaria, meaning six-sided chamber. The picture shows some tiles made from Petoskey stones, and you can see that each polyp has six sides. Mixed in with them are clams, crinoids, trilobites, fish, and cephalopods. Studies of the Petoskey stone show the coral lived on plankton which are microscopic life forms that live in warm oceans. Petoskey, Michigan is NOT a tropical paradise and the Devonian period when these life forms lived lasted a long time, so the Devonian reefs are very thick. The whole state of Michigan is a bowl with these fossils found all around the state. In the middle of the bowl are coal, oil, peat, sulfur and natural gas deposits. The dilemma is how these rock formations got to be the way they are and where they are.

Some religious folks might suggest that this is a deposit produced by the flood of Noah. The problem with that explanation is that this is not a flood deposit and is not a product of violence. Genesis 7:11 tells us that “all the fountains of the great deep were broken up and the windows of heaven were opened.” I would take my students on a field trip to the Shedd Aquarium in Chicago to see a reef display. The rocks being formed and making up the reef are identical to the ones we see in the Devonian deposit. The fossils don’t show a violent end, but instead, they show a slow, gentle formation process. Calcite, silica and other minerals have replaced the original material in the cells of the Petoskey stone animals, giving a dazzling array of colors.

When God created “the heaven and the earth” (Genesis 1:1), the Bible simply states that He did it – not how He did it. At the end of verse 1, there were Petoskey stones in Devonian reefs, and oil, gas, coal, and the other resources were being formed. A change was coming that would make the conditions of the Earth more hospitable for human life, and God knew what we would need for an advanced civilization. Having a warm ocean covering the entire state of Michigan was not an environment humans could thrive in, but it was a tool God used to prepare the resources for human life.

There is no dilemma if we take the Bible literally and accept only what it says. Locking the creation account into a denominational theological tradition does violence to the Genesis account and causes young people to question the truth of the Bible. On the other hand, as they admire the beauty of the Petoskey stone jewelry they have made, people can realize that God has done some special and beautiful things to prepare a home for us in this life.

Does Intelligent Design Destroy Science?

Does Intelligent Design Destroy Science?Skeptics claim that Intelligent Design destroys science. This claim shows how badly the skeptics misunderstand intelligent design.

The dictionary defines science as knowledge. When we do scientific experiments and make observations, we are trying to gain knowledge. We apply that knowledge to those situations where we can gain more knowledge. We never just say “God did it” and stop investigating. We continue experimenting because we want to understand how and why God did it. Believing that there is design in all aspects of the creation never stops us from looking for a deeper understanding. Naturalism is frequently just the opposite. A classic example of this is Junk DNA.

As naturalists examined the DNA in various animals, they found that there was DNA that didn’t seem to be necessary. They called it “Junk DNA” assuming that it was a byproduct left over from the evolutionary process. For many researchers, that was the end of the story. No further experiments were designed to find a purpose for junk DNA. In this case, a naturalistic view and assumption stopped the scientific investigation, or at least slowed it down.

A biology professor chastised me for referring to junk DNA as a dead-end street. His exact words were “God doesn’t make any junk.” The assumption that junk DNA wasn’t junk led to further investigation. That research now tells us the so-called “junk” has a purpose and plays a vital role in life processes. Believing that everything we see was created with a purpose and a design, and wanting to understand that design is a great catalyst for scientific investigation.

Historically, most of the significant discoveries of science over the past 1000 years have been made by scientists who recognized purpose and design in the cosmos. They were striving to understand that design. In our quarterly journal (which you can read on doesgodexist.org), we have a column titled “Scientists and God.” We present statements by leading scientists about their faith and their recognition of purpose and design in the creation. Does Intelligent Design destroy science? No, it supports science.

We quoted Albert Einstein in our first quarter journal for 2019 when he said:

“We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written the books. It does not know how. It does not understand the languages in which they are written. The child dimly suspects a mysterious order in the arrangement of the books, but doesn’t know what it is. That, it seems to me, is the attitude of even the most intelligent human beings toward God. We see the universe marvelously arranged and obeying certain laws but only dimly understand these laws.”

Whether we study biology or quantum mechanics, Intelligent Design enhances science because the universe was intelligently designed.

God’s Horticulture System

God's Horticulture SystemOne of the most interesting designs in the natural world is the way plants are seeded. For plants to grow, there must be soil, moisture, and the planting of the seeds. Many places have moisture and soil that could support plant life, but how do you get the seeds to that area? The solution is God’s horticulture system.

In our area of the world, we have seen human influence cause an area to be bare of significant trees or vines. The building of highways or the destruction of fires and floods can leave an area completely void of any kind of plant growth. Around the interstate highway system in our area, we see the growth of red cedars. These desirable trees are slow growing and can become valuable timber. The state doesn’t plant trees, and yet many red cedars are growing along our highways.

The animals planting these evergreens are birds. The cedars provide valuable habitats for the birds, and the birds plant the trees. Cedars produce blue berries that the birds eat. If you put one in your mouth, you would cringe at their bitter taste and obnoxious consistency. Birds eat them with zest and in large quantities. Birds get nutrition from the berries, and their digestive systems are specifically designed to process the seeds for growth. The birds drop the seeds along with natural fertilizer in barren places. Birds and trees benefit from this symbiosis in God’s horticulture system.

Other important seeders are squirrels. They are designed to bury seeds such as acorns, but their brain limitation causes them to forget a percentage of the seeds they bury. The design of fruits and nuts provide nutrition for animal life while the animals provide a means for the plants to grow in places far from their ancestors.

When scientists look at the diet of dinosaurs by examining their petrified excrement, they find that dinos were the seeders of their day. The plant-eating dinosaurs spread the seeds of the plants they ate along with nutrients that allowed fantastic jungles to form. The meat-eating dinosaurs kept the population of plant eaters under control so they wouldn’t eat all of the plants.

When we look at all the different kinds of seeds, the nutrients they contain, and where they can grow, we see a plan and design. Humans are still learning how to copy God’s horticulture system to feed our growing population.

Major Fossil Find Again

Major Fossil Find AgainWe recently reported on an amazing fossil find in Qingjiang, China. That discovery allows us to learn more about the Cambrian Explosion of life on Earth. Now we have another major fossil find. This one is near Bowman, North Dakota. This fossil trove validates the asteroid collision in the Gulf of Mexico and explains the extinction of the dinosaurs.

One of the assumptions of Darwinian Naturalists is uniformitarianism. They claim that everything we see can be explained by science and that no process has happened in the past that is not going on today. A process so violent that it would destroy virtually all life on Earth does not allow constant small changes over millennia to produce the biota on today’s Earth.

In 1980 Luis and Walter Alvarez produced evidence that an asteroid had hit the Earth near a Mexican town named Chicxulub. According to the Alvarez hypothesis, that impact contributed to the demise of many forms of life, including dinosaurs. Many years later Antonio Camargo and Glen Penfield provided evidence that there was a large crater in the Yucatan Peninsula. Recently Robert DePalma found a fossil bed that ends any speculation about this event. NationalGeographic.com gave the following description:

“..a 7.5-mile wide asteroid smashed into what is now the Gulf of Mexico. It ripped a hole in the Earth’s crust some 50 miles wide and 18 miles deep. Mega-earthquakes and colossal tsunamis rippled out from the impact site, and billions of tons of molten rock was hurled into the sky and across thousands of miles. That debris fell back to Earth as tiny globs of glass known as tektites in a pulverizing rain that lasted for 45 minutes.”

The major fossil find discovered by DePalma near Bowman, North Dakota, is full of fossils of sea creatures mixed up with trees and land-dwelling animals. The gills of the fish are clogged with tektites. There seems to be very little doubt that this deposit is confirmation of the asteroid collision.

The present is not a clear picture of the past. Processes have taken place that are not happening today. The story of life on Earth is far more complex than either Darwin or Moses could have understood. Given the number of asteroids that we know exist in space, it is incredible that our planet has been spared another impact, but maybe Someone is looking out for us.

Trees, Carbon Dioxide, and Global Warming

Trees, Carbon Dioxide, and Global Warming

The big news in environmental concerns for the past ten years has been the apparent rise in the average temperature of planet Earth. The planet has had more dramatic global warming and cooling in the past, but the magnitude of warming today has to be alarming to any thinking person who takes the time to look at the data. It seems likely that human contributions to global warming could be substantial, but the extent of human influence is still being debated. In any case, it seems wise to work toward minimizing what we do contribute. Research proves a relationship between trees, carbon dioxide, and global warming.

The Creator has given us a cheap, effective, permanent solution to controlling the amount of carbon dioxide in the atmosphere.
The answer lies in the trees that God gave us from the beginning. Here is some information about how trees can remove carbon dioxide from the atmosphere as presented in Scientific American, April 2019 page 7:

One tree can store an average of 48 pounds of carbon dioxide in a year.

If agroforestry were practiced, 9.28 gigatons of carbon dioxide would be sequestered by 2050. (Agroforestry is a land use management system in which trees or shrubs are grown around or among crops or pastureland.) Trees increase farm productivity and give farmers revenue through fruits, nuts, and timber while storing carbon dioxide.

Landscape restoration would sequester 1.7 gigatons of carbon dioxide every year.


There is a direct relationship between trees, carbon dioxide, and global warming. The bottom line is that keeping forests intact can go a long way toward saving the planet, and that just means taking care of what God gave us in the beginning.

Alien Invasions Causing Extinctions

Alien Invasions such as the Brown Tree Snake on Guam cause extinctions

New research published in the journal Frontiers in Ecology and the Environment on March 4, 2019, indicates that alien invasions are causing extinctions of native animals. Humans are mostly to blame.

When humans throw the world of plants and animals out of balance, the result is extinctions. We can destroy God’s designed balance when we introduce a non-native species into an environment. The introduced species without natural predators uses up local resources leaving native species without food. There are many examples.

One example is the brown tree snake (Boiga irregularis) which was accidentally introduced to Guam aboard a military cargo ship after World War II. Those snakes are native to Australia and Indonesia where natural predators control them. On Guam, they have decimated 50 percent of the native bird and lizard species and two of the three bat species on the island. The brown tree snakes considered those native species to be tasty treats, and the snakes had no predators to control them. The result was the extinction of many species, some of which existed nowhere else on Earth. Alien invasions of brown tree snakes forever changed the ecosystem of Guam.

In other cases, humans throw nature out of balance by their direct actions. An example of that is the over-hunting of sea otters. Sea otters kept the purple sea urchins in check. Steller’s sea cows (Hydrodamalis gigas)were giant relatives of manatees, and they lived on kelp. Without control by sea otters, the purple sea urchins ate so much of the kelp that Steller’s sea cows had no food, and they became extinct. However, the research project indicated that direct interference by humans in cases like this has less impact on extinctions than the alien invasions have.

Sometimes humans make the mistake of bringing in another non-native species to control the first one. That technique often makes the problems worse. Usually, by the time people discover the problem of alien invasions, it’s too late to fix it.

The research concludes that 25 percent of plant extinctions and 33 percent of animal extinctions were caused by alien invasions – the introduction of non-native species. The bottom line is that humans have not been good stewards of the planet God has given us to enjoy and protect. God gave humans the responsibility to have dominion over creation and “rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground” (Genesis 1:28). Romans 13:1-4 indicates that those who rule over people have the responsibility to protect. We might say the same of us who rule over the creatures.
