Why Venomous or Poisonous Animals?

Why Poisonous Animals? Eastern Coral Snake
There are 2700 known species of snakes on this planet. Of all those, 412 species, or 15.2%, are venomous. Five hundred thousand people are bitten every year, and 40,000 of them die. People are afflicted by poisonous lizards (two varieties), frogs, salamanders, and a variety of toxic insects. This brings up the question of why venomous or poisonous animals exist if a loving God made all things.

If you or someone you know has suffered an attack by one of these animals, you know that even when it is not deadly, it’s still a very unpleasant experience. The skeptic and even the non-skeptic is moved to ask why God would create a reptile or amphibian that could cause such terrible discomfort to humans. Why should an innocent child die because of picking up a pretty ribbon that turned out to be a coral snake?

If you have experienced an encounter, no canned explanation will make the pain and loss go away. But can we make any sense of why venomous or poisonous animals exist?

We must first begin by recognizing that God may not have created these animals as they are today. God did not create many animals (dog and cattle breeds for example) as they are today. They have changed over the years. It is possible that the same is true of poisonous animals, and their original ancestors may not have been deadly. However, the complexity of the poison systems in reptiles and amphibians seems to make this explanation a little imaginative, if not impossible. Even if true, it does not remove God’s awareness of the situation.

A better answer to this question of why venomous or poisonous animals exist lies in the wisdom and planning of God. The Bible says we can know God exists and see His wisdom by looking at the creation. (See Romans 1: 19-23; Psalms 19: 1.) The more we learn about the creation, the more we see God’s design.

One thing we have come to understand is the need for balance in ecosystems. We know that all living things serve a purpose in their natural setting. Animals and insects eat plants which keep the plants from crowding themselves out. Carnivorous animals keep the plant-eaters from wiping out their food supply. Because animals do not fear death as we do, the system is not as cruel and as callous as some would have us believe. In a balanced system, things generally function smoothly and efficiently.

One of the critical factors in maintaining balance is the survival of reasonable numbers of all species. Most reptiles and amphibians are soft-bodied, slow, and generally vulnerable. Camouflage protects some, but the venom or poison glands of others are necessary to do the job. Not only does this protect that animal, but any animals that look similar. Venom also helps the animals catch their food. Rats and mice are the primary food source of many snakes, but without the venom, the snakes could never catch them. Very few venomous snakes or poisonous animals of any kind will attack a human. Most bites occur when a person molests an animal. The obvious purpose of the poison is defense and obtaining food. Accidents do happen, but the poison was not given as a device to be used on humans.

Another important factor is that venomous and poisonous animals provide medicines that we cannot secure from any other source. Medicine from snake venom stops the agents which cause rheumatoid arthritis. There are many other examples of ways science has found to use the poisons from animals.

We can see that there are reasons why venomous and poisonous animals exist. Venomous animals do not prove that God didn’t thoughtfully and intelligently design the creation. We sometimes have to look a little more closely to see the ultimate wisdom of the Creator.

God’s Elevator — The Vortex

God's Elevator — The Vortex
One of my favorite demonstrations as a physics teacher was to put a student on a frictionless stool and spin them around with their legs extended out in front of them. I would then tell them to pull in their legs. When they did that, their angular velocity increased dramatically—they spun faster. We see this when a spinning figure skater pulls in their arms and legs causing a dramatic increase in their rotational speed. This is an excellent demonstration of the conservation of energy and angular momentum. It is also a design feature that enables a wide variety of living things to fly without prohibitive losses of metabolic energy. We call it God’s elevator.

Instead of solids, what happens if the material that is spinning is a fluid – water or air for example. When water goes down the drain in your sink, it picks up speed as it gets near the center. In the very center, there won’t be any motion at all. In a hurricane, warm air is rising in the center, and as air rushes in to replace the rising air, it increases in speed. The center with no air rushing in is the eye of the hurricane, and the maximum velocity is in the wall near the eye.

A less dramatic example of the vortex is the convection cell on a hot summer day. The Sun heats the ground which then heats the air near the ground. The heated air rises, and as it does, the edges of the air are cooled by contact with the colder air around it. This creates a doughnut-shaped thermal vortex that rises to make an invisible, energy-saving elevator for any organism that can get into the doughnut. What this means is that an animal like a hawk does not have to beat its wings and spend enormous energy to soar to a high elevation. This is a huge saving in metabolic energy. An amazing number of living organisms use God’s elevator to get high into the sky and travel very long distances.

Charles Darwin, while sailing on the Beagle, noticed a mass of spiderlings 60 miles off the South American coast. These organisms are terrestrial creatures, but they were able to travel enormous distances by using vortices. Moths use vortices to make journeys from where they are to new areas.

Recent studies of birds have shown that the wings of a bird create a vortex system which is like a ladder. There is almost no lift produced by the bird’s wings on their upstroke, but the downstroke creates a vortex. That vortex combines with vortices on the wing tips making a ring. The combination of these ring vortices makes a zigzagging ladder-like system which lifts the bird. This allows the bird to use a smaller amount of energy than if it merely powered itself through the air. That is why the birds in your backyard fly in a zigzag pattern rather than a smooth path.

Blackfly larvae that live on the bottom of a stream position themselves so that water flowing over the bottom of the tube-shaped larva goes faster creating a low pressure rising along their bodies. The resulting vortex brings up food particles along the floor of the stream to the filters that extend out the top of the larva. The number of examples of living things that use vortices to feed or to conserve energy as they travel seems to be endless.

How do these animals know to use the vortex effect? The way they position themselves and how they use the vortices in their environment works to their advantage. God’s elevator is a great testimony to His wisdom of design in the creation. We can know there is a God through the things He has made and how they use things like vortices to survive (Romans 1:20).

Why Roosters Don’t Go Deaf

Why Roosters Don't Go Deaf
Roosters are loud! They can hit volumes as high as 140 decibels which is the level of sound on an aircraft carrier deck. For humans, a noise above 120 decibels, about the level of a chainsaw, can cause permanent hearing damage. So you may wonder why roosters don’t go deaf.

Belgian researchers writing in the journal Zoology have the answer. They examined the skull structure of the birds. The researchers found that they have a built-in defense against loud sounds in the form of a sound barrier. When a rooster adjusts its head and neck to crow, small flaps of tissue close the ear canal. They effectively act as earplugs to dampens the noise significantly.

On top of that, the study reveals that roosters can regenerate the tiny hair cells deep within the ear that can become damaged by loud noises. Humans can’t do that, which is why deafness caused by loud sounds is permanent for us. For roosters, a degree of deafness would likely only be temporary if it happened at all.

“Micro-CT scans of a rooster and chicken head show that in roosters the auditory canal closes when the beak is opened,” the researchers wrote. “In hens the diameter of the auditory canal only narrows but does not close completely. A morphological difference between the sexes in shape of a bursa-like slit which occurs in the outer ear canal causes the outer ear canal to close in roosters but not in hens.”

So now you know why roosters don’t go deaf. God’s design in every living thing on Earth shows wisdom and an exceptional understanding of the problems that each species faces. The more we learn about the creation, the more we understand the wisdom and creative nature of God. “We can know there is a God through the things He has made” (Romans 1:19-20).

Walnut Sphinx Accordion Worm

Walnut Sphinx Adult Form
One of the amazing things that we see in the natural world is that animals are designed so that they do not get wiped out by predators. A classic example is a caterpillar, which has no easy defense against birds who can find them even though camouflage is one of their primary defenses. The North American walnut sphinx moth caterpillar employs an unusual defense mechanism that gives it the nickname accordion worm.

This caterpillar is about two inches long and has air holes in its sides. It can compress its body to force air out through the holes. The accordion worm does this when threatened by a bird predator. The holes are spaced and designed so that the air passing through them sounds like the alarm calls of the particular bird species that threatens them. The whistle is not just a little squeak. The sound level is more than 80 decibels compared to a normal conversation which is around 50 to 60 decibels. When the caterpillar makes the sound, the birds that would eat the caterpillar scramble out of the area. Researchers from the University of Washington tell us that this is the first incidence of a deceptive alarm call between an insect and a bird.

God provides for all of life on our planet, and the complexity of keeping things in balance is remarkable. As we see the balance of nature becoming upset by human actions, we have to be impressed with what a delicate system of life the Earth contains. Romans 1:18 tells us that we can know God exists through the things He has made. Proverbs 8:1-6, 22-31 reminds us that wisdom has been a part of God’s creative process from the beginning.

If the accordion worm could not survive, it would not become the beautiful North American walnut sphinx moth in the picture. More and more we realize how important it is to take care of what God has created for us.

Blaming California Wildfires on God

Blaming California Wildfires on God
I am writing this article near Redding, California. We have been involved in lectureships in California during this month of August 2018. The fires that are burning in this state have been a constant source of inconvenience for us. They are a major tragedy for people here who have lost homes, businesses, and health. Smoke makes travel difficult, but for people with respiratory problems, the smoke can be lethal. Over and over we have heard references to “why did God do this to us” or in other cases “thank God for…” While we understand the emotions that go with all that is happening, we need to stop blaming California wildfires on God.

While working in California, we are blessed to be with Keith Crummer. Keith has been an ecosystem manager and forest management expert in California for over 30 years. He has degrees in forest management from the University of California at Berkeley and from Oregon State. As we discussed the incredible damage of this current series of fires, Crummer just shook his head in sadness. He told us that what is happening in California was caused by human ignorance and mismanagement.

One fact that astounded me is that there are more trees in the United States now than have ever existed in the history of this area. Before the white man arrived on the scene, trees grew and died just as they do today. When the biomass accumulated on the forest floor, small fires set by lightning or by spontaneous combustion eliminated it. Those fires wiped out small trees and allowed grasses to flourish which in turn supported deer, elk, and other mammals. That made the forest less dense. While fires existed, they were small fires that ran out of fuel very quickly.

Then humans moved in and stopped the fires and allowed vast amounts of biomass to accumulate on the forest floor. The trees became so dense that grass could not grow. Crummer said that scientists know that managing the forest involves harvesting the material that falls to the forest floor, thinning the trees, and using the energy that is available from them. This would eliminate the potential for uncontrolled burning because massive amounts of fuel would not be available. It would also allow animals like deer and elk to proliferate. The current fire catastrophe is 100% due to the mismanagement of the environment by people who thought they were doing the right thing by eliminating fires and refusing to allow cutting down trees or removing brush.

In the Genesis account, God told the first humans to “…fill the earth and subdue it, and have dominion over the fish of the sea and over the birds of heaven and over every living thing that moves on the earth” ( Genesis 1:28-30). “The Lord God took man and put him in the garden to work it and keep it…” (Genesis 2:15-16).

God did not tell them to merely preserve the creation. The creation is a living, changing, dynamic entity. It is our job to facilitate the changing Earth. Working and keeping the Earth means to control those things that would destroy what God created including the animals that live on it. We need to stop blaming California wildfires on God. After the fires in Yellowstone National Park, the elk and deer populations returned to levels close to what they were before humans arrived. If we had done what God commanded in Genesis and worked the forests of the western states, the fires today would not be spreading as they are.

So God did not “do it” to those who lost homes. We understand the anguish and desperation that our friends have experienced, but instead of blaming California wildfires on God we need to realize that politicians and bureaucrats have mismanaged the wonderful resources God has given us. Environmental extremists need to understand more fully what must be done to preserve and protect the environment for the benefit of future generations. Followers of Jesus Christ need to let those who are suffering know that we want to help them. God is not the cause of their burden, but He wants to send His people to love and support those who are suffering.

Biomass on Earth Measured

Biomass on Earth Mostly Plants
Biomass is the mass of living biological organisms. If you lumped all living things by category, what group of organisms do you think would have the greatest biomass on Earth? We aren’t talking about the number of individuals, but the mass of the different lifeforms.

The Proceedings of the National Academy of Sciences on May 21 published a study of the different areas of the world and what form of life dominates in those areas. (Click Here to read the full report.) Plants contribute the primary biomass in the terrestrial environment. Animals are primary in the marine environment. Bacteria and archaea (single-celled microorganisms) dominate the deep subsurface environment.

You may find the results surprising. The total biomass of Earth consists of 80% plants. Bacteria make up the second largest biomass at 15%. After that in descending order are fungi, archaea, protists (unicellular organisms that sometimes form colonies), animals (including humans), and viruses. Soil fungi, protists, soil archaea, arthropods, annelids, and livestock all exceed humans in their biomass. Only wild mammals, nematodes, and wild birds have smaller biomasses than humans. In the marine environment the biomass is much smaller than on land, and after animals, the greatest biomass is in protists, archaea, fungi, and finally bacteria. It is interesting that tiny Antarctic krill contribute about the same biomass as humans.

As you think about the biomass on Earth, it becomes evident that for human life to exist, we need a huge biomass of supporting life-forms. It becomes apparent that we must take care of all of the living things that support us. It is also obvious that before human life could exist on Earth enormous preparation was required.

We have to be reminded of the words of the psalmist in Psalms 8: “When I consider your heavens, the work of your fingers, the moon, the stars, which you have set in place, what is man that you are mindful of him, the son of man that you care for him… You have made him ruler over the works of your hands; you put everything under his feet: all flocks and herds, and the beast of the field, the birds of the air, and the fish of the sea, all that swim the paths of the sea.”

Liem’s Paradox and God’s Design

Liem's Paradox and God's Design
People who believe in naturalism face some interesting problems. One of them is the fact that what evolution predicts should happen doesn’t always happen. This phenomenon is known as Liem’s paradox. Let me explain it.

I am reminded of a field trip to the Shedd Aquarium in Chicago when I was in a teacher-training program sponsored by the National Science Foundation. The leader gave us a demonstration of natural selection that was so easy to understand that it could we could use it in teaching low-level biology students the basics of evolution. Three small fish were introduced into a tank containing a northern pike that had not eaten for several days. One was very healthy, one was slightly impaired with several fins missing, and one was severely impaired with most of its fins missing.

We were asked to predict what the pike would do. We all agreed the pike would eat the impaired fish immediately and then the slightly impaired fish and the healthy fish would probably not be eaten. What happened was that the pike chased the healthy fish around and around the tank as we watched for over an hour. The pike never could catch the healthy fish and never ate the other two. There were all kinds of theoretical explanations for what we observed.

Animals are adapted to eat certain foods. Dr. Karel Liem of Harvard University did a study of a fish in Mexico called Minckley’s cichlid. Those fish have highly specialized pebblelike teeth which are perfect for eating the hard-shell snails that are plentiful in their native environment. What Liem discovered was that these fish would swim right past the snails if they could find softer food. They seemed to avoid the food that their bodies had become adapted to eating.

This evolutionary paradox is called Liem’s paradox, and it is seen over and over in nature. Gorillas will walk miles past copious supplies of stems and leaves which is their typical diet, to get soft sugary fruits that are harder to reach and require long walks. Gorillas in captivity will avoid fibrous foods like celery if they are offered sugary, fleshy fruits, even though those fruits are harder to digest and not good for them.

Liem’s paradox is not hard to understand if we believe that God designed animals to live in specific habitats. The design of animals is always to meet the most austere conditions in their environments. In the case of Minckley’s cichlid the fish will always have the snails to fall back on in hard times, but by being diverse in their diet, they save the snails for times when food is not readily available.

In Uganda’s Kibale National Park there are two different species of monkeys–the mangabey monkeys and the red-tailed guenon monkeys. The mangabey monkeys have flat, thickly enameled molars that allow them to crush hard, brittle foods. The red-tailed guenon monkeys have thinner teeth but have come to share the environment with the mangabey monkeys. Both species of monkeys eat the soft fruits and fleshy young leaves that are around them. In 1997 there was a severe drought, and the soft fruit and leaves were no longer available. The mangabey monkeys survived because they could crack seeds and get at hard foodstuffs which they did not eat until they had to. Animals are designed to get through the hard times but will pass up their special adaptions designed for survival so they can eat preferred foods.

We humans do the same thing. There are times when we eat something we may not like in order to survive, but unlike most animals, our bodies are designed to eat just about anything. We need to remember, “I will praise thee, Lord, for I am fearfully and wonderfully made” (Psalms 139:14) when we look at the diversity of stuff to eat in our local supermarket. We are reminded that Liem’s Paradox is only a paradox to those who are committed to naturalism.

Painted Lady Butterflies Out-migrate Monarchs

Painted Lady Butterflies Out-migrate Monarchs
One of the most amazing things we see in the natural world is the ability of some living things to make incredible migrations. In the past, we have described the monarch butterfly’s migrations from wintering areas in Mexico to northern parts of the United States covering a round trip of about 10,000 kilometers. However, we see that painted lady butterflies out-migrate monarchs.

Scientists have studied how the monarchs navigate such incredible distances with formidable obstacles in their way. Biologists have proposed a variety of models as to how these fragile butterflies could acquire such an ability. However, in the case of the monarchs, the journey is not made by a single butterfly but by a succession of generations.

Science News for July 21, 2018 (page 4) told about a study of another butterfly with an amazing migration. It has the scientific name Vanessa cardui and is commonly known as the painted lady butterfly. These butterflies live in Southern Europe and migrate to Africa in the fall–a distance of 12,000 km. That’s 2000 kilometers farther than the monarchs, and the journey involves crossing the Sahara Desert. As with the monarchs, scientists had believed that the migration involved several generations. New techniques allowed researchers to put markers on the painted ladies when they were caterpillars. We now know that at least some of the butterflies make this incredible journey in one lifetime.

When you look at the barriers to this migration including changes in wind direction, mountains, desert, and storms it is difficult not to be impressed with how the painted lady butterflies out-migrate monarchs. Trying to construct a possible model based on chance processes involves so many assumptions that it is hard to accept that this ability can have an evolutionary explanation. Believing that God’s creation included building a DNA set of instructions that allows the painted ladies and monarchs to migrate is not just an assumption, but the weight of the evidence supports it.

Tools and Intelligence

Tools and Intelligence
We tend to equate the use of tools and intelligence, but do they necessarily go together? Many kinds of animals use twigs, stones, or other objects as tools to gather food, to groom or defend themselves, or sometimes just to play. We are very familiar with how dogs can be taught to play with a ball or stick. Intelligent animals such as primates, mammals, and birds use or even create tools from materials around them.

Sometimes animals learn tool-use by watching other animals or humans. At other times tool-use seems to be instinctive. An internet search for “animals using tools” brings up many interesting videos. Ever since animal researcher Jane Goodall discovered chimpanzees using leaves and twigs as tools to obtain food in 1960, some people have suggested that tool-use is proof that humans are not unique from other animals—we have just evolved greater intelligence.

But the question is, “Does it take intelligence to use tools?” The short answer is “No.” Decorator crabs camouflage themselves with objects and plants, and they may pick up a sea anemone and use it to sweep across the sea floor picking up food. The assassin bug takes material from a termite’s nest to camouflage itself while waiting to grab a termite emerging from the nest. It then kills the termite and uses it as bait to coax other termites out of the nest. The larva of the green lacewing camouflages itself with objects such as sand grains to hide from and capture aphids.

Crabs, assassin bugs, and insect larvae have no “thinking” brain. They are not capable of being taught or learning by observation. How can they use objects as tools? In some cases, if the first of their kind could not use these tools, the species would have become extinct. We suggest that the Creator has “programmed” these unintelligent animals with the instincts they need to survive.

So as we consider tools and intelligence, we see unintelligent creatures using tools by instinct, and more intelligent creatures learning to use tools. Obviously, no animals can create and use the highly sophisticated tools that humans have, including computers, robots, and cars. But it’s the spiritual nature of humans that makes us different, and not our tools. Only humans worship God because He created us in His image.

Gorilla Named Koko Dies

Gorilla Named Koko Cartoon
On June 19, 2018, the famous lowland gorilla named Koko passed away. Koko was famous because she learned the sign language of the deaf and could comprehend 2,000 words and “speak” 1000.

Koko was born in captivity and lived in the Gorilla Foundation in California. Her trainer, Francine Patterson, began training the gorilla in the sign language of the deaf when she was about a year old. Koko got major attention from the entertainment industry and the media. Robin Williams and Fred Rogers interacted with Koko and gave her significant publicity. National Geographic ran a documentary on her in 1978.

A line in The Week (July 6/July 13, 2018, page 12) by Molly Roberts summarized Koko’s impact: “Science is still far from establishing how much apes truly resemble humans mentally and emotionally, but in Koko’s case, it may not really matter. What mattered is that we looked at this creature, and somewhere in Koko’s eye, we saw ourselves.”

There is no question that Patterson’s work with this gorilla was a remarkable demonstration of human patience and animal capability. Attempting to prove that the gorilla named Koko is a distant relative of her trainer is quite a stretch. Ms. Patterson became emotionally involved with Koko, and the usefulness of her work with the gorilla scientifically is highly controversial. Skeptics point out that Paterson’s questions were “designed to elicit responses that made it seem as if Koko understood more than she really did, but boy, did we want to believe.”

The commercialization of Koko did much to destroy any scientific value in her ability to communicate. Patterson created a record album in which Koko “picked songs she liked” based on what she listened to. Koko’s capacity to create art was demonstrated by having her copy what Patterson drew. Koko’s ability to select colors for what animal she was supposedly drawing produced some comical results. Koko’s “desire” to have a “pet” kitten was made into a children’s book in 1983. Understanding the concept of a kitten or a pet certainly was not part of Koko’s animal instinct.

We suggest that Koko the gorilla was created in the image of “Penny” Patterson. While this is an amazing achievement and there is much to learn from what Patterson did, the value of Koko to anthropology is very limited. The creation of humans in the image of God has nothing to do with intelligence, language, or the ability to learn and copy. Our spiritual nature is uniquely ours, and humans without training still demonstrate their spiritual nature.
