What I Learned in Paleontology Class

What I Learned in Paleontology Class - Trilobite Fossils
Trilobite Fossils

We want to share with you this article by Phillip Eichman about a class in paleontology, the study of the history of life on Earth based on fossils.

Back in the 70s, I was majoring in biology at Wright State University and needed some elective hours to graduate, so I signed up for a course in invertebrate paleontology. I had already taken a year of geology, and this was an upper-level course. However, what I learned in paleontology class when I was a young Christian made the course worthwhile.

I had been interested in rocks since I was a small child. So I began collecting them and found my first fossil before starting school. By the time I was in the fifth or sixth grade, my closet was stuffed with boxes of rocks and fossils, and I had practically worn out my Golden Guide book of Rocks and Minerals.

As a young Christian, I was a little concerned that this course in paleontology might somehow cause me to question my religious faith. But, as it turned out, this was one of my all-time favorite courses.

In the class, we went phylum by phylum, looking at the hard parts, noticing the main characteristics of the group, and learning how to identify the fossils. It was easy to see that the various groups developed, or evolved, over time, but they were still part of that major group. For example, the gastropods were still gastropods, and the brachiopods were still brachiopods. The same was true for the cephalopods, corals, trilobites, and others. There was no confusion caused by a huge number of “intermediate forms” that you hear about so often in the popular media.

This lack of intermediate forms is not consistent with the “amoeba to man” theory of evolution. It is, however, consistent with the biblical account of God creating various “kinds” of living things with the ability to change over time, or evolve, within those groups.

As has been pointed out many times in the Does God Exist? program, science and the Bible are not enemies if we understand both in the proper way. Instead of causing harm to my faith, what I learned in paleontology class and my study of fossils only strengthened my belief in God as the Creator.

Designing an Elephant Trunk

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.”

Donkeys Digging Wells in the Desert

Donkeys Digging Wells in the Desert

We don’t ordinarily think of donkeys as diggers, especially not as vital to the desert environment. A researcher from Aarhus University in Denmark has made a discovery that shows a special provision God made to use donkeys to provide water for other life forms. Erick Lundgren has documented donkeys digging wells in the desert. In 2014 Lundgren studied feral horses and donkeys and noticed them digging holes deep enough to reach groundwater.

From 2014 to 2018, Lundgren mapped groundwater in Arizona’s Sonoran Desert and found that holes dug by donkeys provided 74% of available water for all forms of life in the area. The donkeys seemed to know where to find water, and 57 vertebrate species from migratory songbirds to mountain lions and even a bear came to the donkey wells to drink.

It is fascinating that this is not a local anomaly. Researchers have documented donkeys digging wells in Central Asia, so this action is built into the donkey’s genome. Attempting to make a case for accidental donkey well-digging fails when isolated populations have the same instinctive drive. They use it not only to survive themselves but to benefit an entire ecosystem.

Research into donkeys digging wells shows that the donkeys know where to dig because the digging is not random. The wells dug by donkeys decreased the distance between water sources to an average of 843 meters, making essential water available to more animals with less tension. We suggest this is a beautiful example of God’s design allowing animals to live in environments that would seem unlikely to support life.

Fossil Apes and Human Evolution

Fossil Apes and Human Evolution

Most of the media versions of human evolution are fictitious and inconsistent with the evidence. That is the finding of a study conducted by scholars from the American Museum of Natural History released in the journal Science for May 7, 2021, titled “Fossil Apes and Human Evolution.”

“When you look at the narrative for hominin origins [referring to bipedal apes and modern humans], it’s just a big mess – there’s no consensus whatsoever.” That’s a quote from Sergio Almecija, the lead author and a senior research scientist at the American Museum of Natural History’s Division of Anthropology. He went on to say, “People are working under completely different paradigms, and that’s something that I don’t see happening in other fields of science.” 

According to the study of fossil apes and human evolution, science has a wealth of fossils, but “many of these fossils show … combinations of features that do not match expectations for ancient representatives of the modern ape and human lineages.” We hasten to add that the museum’s article does not deny human evolution but clearly shows that the story given to the general public is a false impression that our history is a cut and dried factual record on which all scientists agree.

This year marks the 150th anniversary of Charles Darwin’s book The Descent of Man, and Selection in Relation to Sex. There will be many articles and a few TV specials on fossil apes and human evolution in which certain well-known anthropologists will sell their view of human physical history. Careful students who know how much evidence is available will see the contradictions, but the general public will not. 

The biblical explanation of human creation is not a detailed physical explanation of how humans were created. Genesis 2:7 tells us, “God formed man of the dust of the ground and breathed into his nostrils the breath of life; and man became a living being.” The Bible does not detail what processes God used to do that creating or what the finished product looked like (skin color, etc.). 

The Bible does tell us the essential factor that human beings were created in the image of God. “So God created man in His own image, in the image of God created He them, male and female created He them” (Genesis 1:27). Whether you view God as merely commanding and man miraculously appearing, or if you think of Him as a potter molding and shaping man’s body, that does not diminish the unique nature of humans. The Bible has an economy of language. We would like to have the details, but that is not the purpose of God’s Word. 

It’s a destructive message to tell humans they are just animals with no unique qualities and no real purpose in existing. Letting people know that they are special, created with a unique spiritual makeup means that all humans are equal in God’s sight and have a spiritual purpose for existing. Like Job, we are key players in the war between good and evil. Relegating humans to someone’s guess as to how we evolved and cherry-picking fossils to do that is not only unfortunate but has the potential to destroy our culture.

Animals Seem to Demonstrate Altruism

Animals Seem to Demonstrate Altruism

Are animals willing to sacrifice their well-being to benefit another animal? Altruism is a human characteristic thought to be missing in animals. As scientists study animal behavior more deeply, they see many cases where animals seem to demonstrate altruism. Those include jumping into a fight to save another animal when there is no direct benefit to the intervening animal. In one case, killer whales were hunting a sea lion. Suddenly two humpback whales charged in and pushed the killer whales away, allowing the sea lion to escape. People observed that happening three times in the same area.

There are also situations where animals seem to demonstrate altruism by giving food away. Vampire bats need a constant supply of blood because they can’t survive more than 70 hours without it. Researchers have seen vampire bats regurgitate blood when an individual misses a meal. In one case, a vampire bat gave away so much blood that it starved to death. Studies of meerkats, a species of mongoose in southern Africa, have shown that one couple will breed the offspring and other adults raise the babies. Studies of bonobo primates have demonstrated that they share food both in captivity and in the wild.

Are those the behaviors we thought that only humans exhibited? One constant danger in studying animals is our tendency to anthropomorphize animal behavior. In other words, we interpret animal behavior in light of human behavior rather than looking at the possible reasons for the animal’s actions. You can see this by looking at how people treat and talk to their dogs. The reality is that the dog has learned where it gets its food, its sensual pleasure, and its security. No matter how much support the dog receives, it will still chase the cat, eat the feces of another dog, and bark at a time that displeases the owner. Dog owners tend to overlook those animal instincts and behaviors, and they may even put clothing on the dog.

Researchers can see that all animal behavior in the wild has some kind of survival benefit. In the cases above, the whales don’t have sympathy for the seal. Killer whales attack humpback whale babies, and the best defense the humpbacks have is to drive the killer whales out of the area. Vampire bats are not successful in getting blood every time they go out, so sharing benefits all of the bats because the next night might be their time to be unsuccessful. A similar scenario is present with monkeys sharing.

These animals seem to demonstrate altruism but still resort to survival behavior when under stress.
Chimps raised in human homes do not become humans. When a human invades their territory, they resort to violent behavior. At the same time, pure altruism is a trait available to humans, but not all humans demonstrate it at all times. There is a saying that humans can act like animals, but animals cannot act like humans. The death of Christ on the cross is the classic example of sacrificing one’s self to benefit even those who reject you.

A Rock’s Not Alive

A Rock's Not Alive

The following came to us from our friend Dr. Phillip Eichman, who has a Ph.D. in biology.

For many years I began the courses that I taught in Fundamentals of Biology and General Biology by bringing two things to class: a rock and something living, usually a plant from the greenhouse. Most of the students had never seen me before and must have wondered why I brought those things to class. One day I surprised the students even more with a turtle that I rescued from the middle of the road. The point that I wanted to make is that there is a vast difference between a nonliving thing and a living thing. The expression “a rock’s not alive” comes from an old Sesame Street song and makes the same point.

A rock’s not alive. It is made up of the same chemical elements as the plant or the turtle, but that is where the similarity ends. Anyone who has taken a biology course will realize that even the simplest living thing has a complex organization. It is capable of taking in and using energy, growing and reproducing, and responding to the environment.

Obviously, something happened to make living things so different from nonliving matter. Either it is a big coincidence, or some higher intelligence planned and directed the formation of life on Earth. More than forty years of studying and teaching biology have convinced me that the latter of these is true. The world in which we live is not an accident, but rather the handiwork of a creator that we call God (Psalm 19:1).

Human-Macaque Chimera Created

Human-Macaque Chimera and Ancient Greek Mythology

A chimera is a living organism made up of parts from different organisms. You have heard myths about a half-woman, half-fish mermaid, and a human torso and head on a horse’s body and legs. Those would be chimeras if they actually existed. Now scientists have created a human-macaque chimera.

Scientists at the Salk Institute in California injected human stem cells into macaque embryos. They allowed the embryos to grow for only 20 days before destroying them. The stated purpose for creating a human-macaque chimera is to find a way to grow human organs for transplant and to develop new drugs.

This reminds us of a science fiction story of chimeras turning into monsters that threaten human beings. The term “chimera” (kye-MER-uh) comes from an animal in Greek mythology with a lion’s head and body, a goat’s head protruding from its back, and a tail with the head of a snake. Imagine what a human-macaque chimera might be like.

This experiment raises bioethical questions. Just because researchers can do this, should they do it, and what kind of research should they carry on? Insoo Hyun, a bioethicist involved in this research, says that chimeras have “the potential to radically humanize the biology of laboratory animals.”

The morals and beliefs of the scientists doing the research become a significant issue in situations like this. We need people with Christian values involved in making these decisions to ensure that everything is done to relieve human pain and suffering, not to create half-human creatures. God has provided the blueprint in DNA, but it is up to humans to decide how to use it. Whether it is for good or evil is an old biblical question.

Story of Earth’s History and Life

Chicxulub Story of Earth's History and Life

In the Yucatan Peninsula and the Gulf of Mexico, the Chicxulub Crater tells a story of Earth’s history and life. The fundamental assumption of neo-Darwinism is that the only processes operating on Earth in the past are processes going on today. This principle, called uniformitarianism, doesn’t work if there have been radical changes on Earth in the past. A catastrophe that wiped out all life would mean that life would have to start over again. Evolutionists have devised elaborated theories to dance around this issue, such as Stephen Jay Gould’s punctuated equilibrium.

A study released in the journal Science Advances on February 24, 2021, involves an exhaustive study of the Chicxulub Crater. This crater is 125 miles (201 km) wide and dates back to the time of the dinosaurs. Many scientists suggested that an asteroid collision produced the crater. Evolutionists resisted that explanation because of the catastrophic effect it would have, and certainly, it is not happening today.

In 2016, researchers took drill cores at Chicxulub to a depth of 2600 feet (792 m). Analysis of the cores has now produced an iron-clad case that an asteroid collision created the Chicxulub Crater. Iridium is an element found in most asteroids, and scientists found massive amounts of it in the center of the crater, with decreasing amounts as one moves away from the center.

In addition to the drill core at Chicxulub, scientists have found iridium in geologic layers worldwide. That indicates tiny fragments of the asteroid were blown into the atmosphere in large quantities blocking the Sun’s light for several years, or even decades. Independent studies have shown that Earth’s surface temperatures dropped by as much as 50 degrees Fahrenheit (10 C), meaning that any dinosaur could not have survived.

This research tells a story of Earth’s history and life that we suggest shows how God was preparing the planet for human life to exist. Suggesting that humans and dinosaurs could have lived together indicates ignorance of the nature of life in the age of the dinosaurs. Not only was Earth’s surface temperature high, allowing massive deposits of coal and other resources for later humans, but the dinosaurs were not a form of life that humans could survive alongside. Evidence shows that T. rex hunted in packs. (See The Week, May 7, 2021, page 24.) The notion that a T. rex could have been a family pet that children could ride, as some religious groups have proposed, is ludicrous.

This story of Earth’s history and life fits with Genesis 1:1, with God using natural processes to prepare planet Earth for humans. Not only is Chicxulub a problem for neo-Darwinism, but it provides more evidence for the integrity of the biblical record when it is taken literally and not twisted to support denominational teachings.

Periodic Cicada or Magicicada

Periodic Cicada or Magicicada

In recent years, people have paid a great deal of attention to insects and how they benefit humans. Some insects pollinate our fruit trees. Others provide food for birds and a variety of mammals–even humans. Insects also help convert waste into valuable nutrients. One of the dangers to the total insect population is over predation because so many animals eat them. One insect species solves the problem in a unique way. It is the periodic cicada or Magicicada that appears every 17 years. These insects suddenly emerge from the ground in massive numbers, as many as 1.5 million per acre, to overwhelm their predators.

Dr. Cliff Sadof of Purdue University has headed up research into the life cycle of cicadas. He tells us why we will have a massive amount of noise during the coming weeks from treetops all around us here in Indiana and other areas of the eastern United States. When the soil temperature reaches 64 degrees F at a depth of eight inches, the periodic cicada or Magicicada will start crawling out of the ground. In massive numbers, they climb up trees to molt. After molting, their bodies will be white as they unfold new wings. In a few hours, their bodies will harden, and the males will fly into the treetops and start singing to attract females.

After mating, the females will lay eggs in twigs with a saw-like egg-laying device called an ovipositor. After the eggs hatch, the nymphs will fall from the treetops and burrow into the ground, where they feed on sap from the tree roots. Seventeen years later, the nymphs will emerge and become adult cicadas repeating the cycle.

The cicadas are easy to see, good to eat, and plentiful in huge numbers. Birds, squirrels, and other insect-eating animals will gorge on the cicadas giving other insects a reprieve to recover their numbers. The soil around the trees will be aerated and enriched. The process will prune upper tree branches encouraging new growth.

In Indiana and many other states, the cycle is 17 years. In other regions, the periodic cicada or Magicicada has a 13-year cycle. Trying to explain how such a system came into existence by chance requires a tremendous amount of imagination. We suggest that cicadas are another example of wisdom built into the natural world by God to allow life to exist on planet Earth.

Solutions to the Mosquito Problems

Solutions to the Mosquito Problems
Damselfly

One of the big problems that humans face is mosquito infestations. Most of us know that mosquitoes can carry serious diseases, with malaria being at the top of the list. It is essential to understand that the presence of mosquitos is not a failure in God’s design of the natural world. What are the solutions to the mosquito problems?

Most mosquito species are pollinating insects. Of the problem species, only the females draw blood, usually from decaying remains of animals. Before humans invaded natural habitats, mosquitos were less of an issue than in modern times. The larvae do not survive well in running water, and mosquitos are such weak fliers that even a slight breeze will keep them at bay.

The human response to mosquitos has been badly misdirected. The most common response has been to spray areas with heavy doses of chemicals that kill mosquitos. The problem is that the spraying kills everything else as well. Pesticides do not discriminate between good insects and bad ones. Animals dependent on insects for food are radically affected by massive spraying. Since 1970, nearly three billion birds have disappeared from North America. The solution to mosquito problems is quite simple–let God’s natural agents control the mosquito population.

Dragonflies and damselflies are voracious mosquito eaters concentrating on mosquito larvae. Hummingbirds eat hundreds of insects every day. American bullfrogs have long sticky tongues designed to catch insects, and mosquitos are at the top of their list. Red-eared slider turtles are mosquito eaters, with one study showing a 99% drop in mosquito numbers in ditches where the turtles were introduced. Woodpeckers, warblers, and wrens all eat mosquitos. They are all solutions to the mosquito problems.

Mass spraying creates imbalances in insect populations and kills birds and animals that feed on mosquito larvae. The spray also has serious implications for humans who react to the chemicals, including some forms of cancer. Humans have contributed to the dilemma that mosquitos bring to all of us, but God has natural solutions to the mosquito problems.
