Elephants Show Design and Purpose

Skeptics have maintained that our planet cannot support animals as big and requiring as much food and water as elephants. Such comments are a product of ignorance and the desire to show that a wise Creator could not have designed life on Earth. However, the more we learn about them, the more we see that elephants show design and purpose.

Elephants eat 200 to 300 pounds of food and drink up to 40 gallons of water every day. They can spend 75% of their day eating, and that fact has fueled the skeptical view. What needs to be better understood is that almost 50% of the plant material they eat leaves their body undigested. This makes the elephant the gardener of the rainforest, providing seeds and water in places that would otherwise be barren.

An elephant’s trunk is an incredibly sophisticated piece of equipment with 40,000 muscles that can bend in nearly any direction. An adult elephant’s trunk can pick up a 700-pound weight, but it is sensitive enough to pick up a flower. Elephants can suck up and expel water but do not drink through their trunk – it is not a straw. An elephant’s sense of smell is twice as keen as a dog’s and can detect the scent of food or water 10 miles away.

Elephants use infrasonic sounds to communicate with one another. These are frequencies lower than 20 cycles per second, the lower limit of human hearing. Using low frequencies allows the sounds to be transmitted over very long distances. Studies have shown that elephants can communicate with one another over a span of six miles. Elephant hearing does not just involve its ears. They also hear through nerves in their feet, and their hearing is sensitive enough to distinguish between human voices.

Elephants have the largest brain of any land animal, and the memory section is larger and denser than that of humans. The adage of having a memory like an elephant recognizes this ability, which has shown to be useful in situations such as remembering where water holes were 12 years ago. The design of elephants is so complex that attributing it to blind chance does not seem to be the best explanation. Seeing that elephants show design and purpose, we recognize that life is the product of an intelligent Creator.

Studies of Elephant Trunks

So many designs in living things seem to be beyond any chance explanation that it is difficult to watch a nature program or read a scientific paper without seeing another example. For example, we have recently written about studies of elephant trunks HERE, HERE, and HERE. National Wildlife magazine for the first quarter of 2022 reported on another elephant trunk study.

This report centers on the elephant’s specialized respiratory system, which produces lung pressure that allows the elephant to use suction both on land and underwater. No other terrestrial species can even come close to doing what an elephant can do.

Every day an African elephant consumes 400 pounds of food and drinks several gallons of water. The engineers studying the elephants discovered that they can dilate their nostrils to reduce the thickness of the walls of their trunks, increasing the space inside the trunk by 60%. High-speed video and computer modeling show that the elephants can suction air at nearly 500 feet per second and inhale a gallon of water every 1.5 seconds.

As with previous studies of elephant trunks, this new data makes the elephant even more amazing. As scientists understand specialized equipment, it becomes more and more difficult to suggest that this specialization can be the product of chance. Many species of elephants have inhabited our planet, and their trunks all show specialization, even though the environments they live in vary enormously.

Every living thing on Earth has something to teach us. Therefore, we must take care of our planet and the animals we share it with so we will not lose this information. From studies of ants to studies of elephant trunks, an abundance of life demonstrates the wisdom and design of the Creator.

Elephant Trunks as a Model for Robots

New research shows that using elephant trunks as a model for robots, engineer-designers may soon create machines capable of doing things that no current robot can do. For example, the elephant trunk has 40,000 muscles that work together to allow the animal to pick up a single leaf or lift and move a large log easily.

Researchers used motion capture technology similar to that used to create movies where the movement of animated characters is mapped to the motions of real actors in a studio. Studying elephant trunk movements by this method allowed the researchers to carefully examine the myriad ways an elephant uses its trunk.

The elephant’s trunk has an infinite number of degrees of freedom. We can see a similar property in a limited way in the human tongue. Like the elephant’s trunk, our tongues have no bones, and some of us can curl, twist, and contort them in various ways. The ability to speak requires complex tongue movements.

Using elephant trunks as a model for robots is a real challenge to engineers. Designing a robotic arm with complex movements and strength is an important goal. Looking at the elephant’s trunk design, it does not seem possible that this could be a product of chance. Yet, the elephant’s survival is only possible because of this highly complex appendage.

Some animals have tongues that can do interesting things, but the elephant trunk is unique. By using elephant trunks as a model for robots, we can gain some essential insight into making a robot that can do the things we can do with our hands. It becomes clear that all of nature shows God’s handiwork and teaches us important lessons.

Design of an Elephant’s Trunk

Some of the exciting things about the natural world are the cases where the design is so advanced that any evolutionary explanation is difficult to believe. An excellent example of that is the design of an elephant’s trunk.

Recent ultrasound studies of elephant trunks have shown they are incredibly complex examples of design. The elephant is the only living land animal to have a long boneless appendage. A septum stretching the length of the trunk separates the trunk’s two nostrils. The elephant can expand each nostril’s volume up to 64%. The flow rate of water through the trunk averages about 3.7 liters per second, which would be the same as 24 shower heads operating all at once.

An elephant’s trunk is not just a drinking straw. When the elephant uses the trunk for something other than water, such as food, the nostrils don’t expand, but the elephant uses its lungs to suck up the food. The nostrils can bring air in at more than 150 meters per second, 30 times as fast as in a human’s sneeze.

Research is continuing on the muscular design of an elephant’s trunk. The intricate muscular structure and lack of joints give the elephant a highly complex trunk movement. Engineers have built robotic devices based on the design of an elephant’s trunk,

One researcher commented, “You never know where bio-inspiration will lead.” Designs from Velcro to airplane wings have come about by studying what God has created in living things. Everywhere we look, we see that a wonder-working hand has gone before.

Designing an Elephant Trunk

We all know that elephants have useful trunks. As we learn more about what an elephant’s trunk can do, the more impressive it becomes. Designing an elephant trunk is not a project of chance.

The trunk is not just a snorkel. It is a highly complex device with 40,000 muscles and 150,000 separate muscle fascicles, bundles of muscle fibers. There is no bone or fat in the trunk. The Week magazine published a list of some of the characteristics of a captive elephant at Zoo Atlanta. They include:

1) Inhale water at speeds over 490 feet per second. (That’s 30 times faster than a human sneeze).

2) Issue a 110-decibel trumpet-like blast. (120 dB is considered the human limit without pain.)

3) Suck up food. (A skill thought to belong only to some fish.)

4) Rip up trees and lift 770 pounds. (350 kg)

5) Reach up to 23 feet. (7 m)

6) Hold 2.2 gallons in the trunk. (8.3 l)

7) Detect smells four times better than a bloodhound.

8) Lift a tortilla chip without breaking it.

The more complex a device is, the less likely it is to be the result of an accident or a series of accidents. The difference between the human nose and the elephant trunk is so striking that we should abandon attempts to relate the two. Lead researcher Andrew Schulz from Georgia Tech says that their research “pushes all of the extremes of what we understood animals to be able to do.”

The challenges of designing an elephant trunk strongly suggest that intelligence was involved. This is one more example of the credibility of the statement in Romans 1:20, “We can know there is a God through the things He has made.”
