Design in Hearing

Design in Hearing
One of the amazing features of animals is design in hearing. Humans can hear sounds between 20 and 20,000 vibrations per second (Hertz). That range allows us to communicate through the air and enjoy music. Various animals can hear sounds in different parts of the frequency spectrum.

Dogs can hear frequencies higher than 20,000 Hertz. We call these sounds ultrasonic because they are above the frequencies we can hear. We use ultrasonic sounds for examining the organs inside the human body. We use it to view unborn babies inside their mother’s womb. Ultrasonic sound has uses such as cleaning of jewelry or other items. But we can’t hear it. The ability to hear ultrasonic sounds gives dogs and other animals a defense advantage. Try to sneak up on a dog. If you open a door or step on a floorboard creating an ultrasonic squeak which you can’t hear, the dog will hear and know that you are coming.

Elephants, whales, and other large animals can hear low frequencies and use them to communicate over many miles because low frequencies travel more efficiently through the ground or water. But it isn’t just large animals that use these subsonic sounds. Some small animals, like moles, can also hear low frequencies since those sounds travel well through the ground. If a mole communicated through sounds we could hear, finding and killing them would be easier for their predators and us. Because they communicate at frequencies below 20 Hertz, they are not easily detected by animals above the ground.

Design in hearing also applies to frogs, snakes, and many insects that can also hear very low or very high frequencies allowing them to communicate with others of their kind without detection by different species. Different creatures use various portions of the audio spectrum. If a creature gives off sounds that its predators can hear, they will literally be “dead meat.”

The world of sound rings out loudly the incredible design of the Creator who gave various creatures the ability to hear the sounds they need to hear. We can be thankful that God gave us the ability to hear the beautiful sounds of music and the spoken voice.

Why 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 poisonous. 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 poisonous animals exist if a loving God made all things.

If you or someone you know has suffered an attack by one of these poisonous 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 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 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 poisonous glands of others are necessary to do the job. Not only does this protect that animal, but any animals that look similar. Poison 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 snakes or poisonous animals of any kind will attack a human. Most bites occur when a person molests a poisonous 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 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 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.

World’s Largest Snake- TITANOBOA

World's Largest Snake
It was the world’s largest snake. Fortunately, it is extinct. The computer-generated picture shows what it might have been like if a human had ever confronted a Titanoboa (Titanoboa cerrejonensis).

One thing that many creationists and evolutionists forget is the fact that Earth’s climate in the past was much different from what it is today. To produce animals of massive size, Earth’s climate would have to be much warmer. The temperatures would have been so high that mammals could hardly survive. Cold-blooded (ectothermic) animals in tropical areas today tend to be larger than ectothermic animals found farther from the equator.

While giving lectures in Colombia, South America, we learned about the snake named Titanoboa. Fossils of more than two-dozen of these snakes were discovered in coal mines in northern Colombia. The name means “titanic boa,” and that seems fitting because it measured 48 feet (14.6 m) long and would have weighed 2500 pounds (1,135 kg). For a snake of that size to live, the climate must have averaged 90 degrees F (32 degrees C). It is difficult to comprehend how any mammal, especially humans, could survive in such temperatures.

Why would God have given this planet such an extreme climate? It was needed to support the world’s largest snake, other huge animals, and the massive vegetation they required. What was the purpose of those animals and plants? That environment made possible the coal, petroleum, and other resources that would later be needed by humans to support an advanced civilization. This is one more indication that the prehistory of the Earth had conditions uniquely designed by God to prepare the planet for human habitation.
