Extinction of Plant and Animal Species

Near the end of 2023, the U.S. Fish and Wildlife Service removed 21 species from the Endangered Species Act because they have become extinct. What causes the extinction of plant and animal species?

Many factors lead to extinctions. Dr. Hugh Ross says the fossil record indicates that half of the mammal species that existed at the time of Adam and Eve are now extinct. Human activities that can endanger species include habitat destruction, introduction of invasive species, and introduction of diseases. Of course, animals can endanger people in various ways, including introducing diseases.

Humans have endangered plant species by introducing invasive plants. Plants used for decorative purposes can become invasive. Examples are English holly and the tree of heaven. Some plants that have become invasive were introduced to serve a purpose, such as controlling erosion. An example is the kudzu plant.

At other times, humans have caused extinction by killing large numbers of a species such as the passenger pigeon. Because of hunting and habitat destruction, the dodo bird became extinct within less than a century of its discovery. Humans caused the extinction of the great auk by foolish vandalism. Today, poachers are endangering the rhinoceros by killing them for no good reason. By contrast, human efforts rescued the California condor after it became extinct in the wild.

Woolly mammoths existed alongside early humans, and some scientists say they were essential for the survival of humans in some areas. People used them for food and their skins for protection from the elements. Their bones became tools, building materials, and even musical instruments. These large animals also kept plant vegetation under control while spreading their seeds. We can not always determine the cause of the extinction of plant and animal species, and that is the case with woolly mammoths.

The extinction of the dinosaurs occurred before humans were on the scene. That is good because humans and dinosaurs could not coexist on the land or at the same atmospheric oxygen level. God used them to prepare Earth for humans, and He orchestrated their extinction before He placed Adam and Eve in the garden.

As we look at the extinction of plant and animal species, we learn some essential facts. From the beginning, God had a plan for life as He prepared this planet for us to be here. He gave the first humans the responsibility to take care of the Earth, but we have not done a very good job. Finally, God is still giving us a chance to do better, and we have had some successes. Serving God involves serving others and caring for what God has given us for human flourishing. We can only do that when we submit to His plan for our lives.

A Lesson from the Dart Experiment

A Lesson from the Dart Experiment
Double Asteroid Redirection Test – DART

In September of 2022, NASA steered the DART spacecraft into an asteroid named Dimorphos, attempting to alter its orbit. The experiment was designed to see if we could change the path of an asteroid moving toward a collision with Earth. We can learn a lesson from the DART experiment.

It sounded like a good way to protect our planet from an asteroid impact. Scientists believe an asteroid collision may have caused the extinction of the dinosaurs, and a similar one might cause human extinction. The collision did alter the orbit of Dimorphos, which is comforting to know. However, it also caused more potential problems.

The Hubble Space Telescope observed 37 previously unseen objects accompanying Dimorphos in its orbit around the Sun. These are boulders probably blasted off from Dimorphos by the DART collision. They are not just little pieces of rock or dust. Some of the boulders are as large as seven meters in diameter. Calculations show that the weight of the 37 boulders adds up to 5,000 metric tons – the weight of 300 gravel-filled dump trucks.

This incident reminds us of the story of Frankenstein when a scientist created a being that turned into a monster. Dr. Frankenstein did not comprehend where his creation might go once it was out of his control. These boulders do not pose an immediate danger to the Earth but understand that meteorites striking Earth’s surface are generally quite small. The boulders caused by DART’s impact with Dimorphus would cause significant problems if they hit the Earth.

Humans can learn a lesson from this incident. We are not God, and our wisdom and knowledge are incomplete. As God said to Job, “Who is this that darkens counsel by words without knowledge?” (Job 38:2) In our day of rejecting God and His Word, we must be reminded that altering the design God built into the creation of everything from galaxies to viruses can have tremendous consequences. We have seen that in COVID, and again, we can learn a lesson from the DART experiment.

Dinosaur Tracks and Human Tracks

For many years, various religious sources have claimed that dinosaur tracks and human tracks exist in the same rock strata in Glen Rose, Texas. We have visited the site several times and have published articles on the tracks. Our studies were not just at Dinosaur Valley State Park, operated by the state of Texas, but also at Jake McFall’s ranch, where the original film “Footprints in Stone” was made fifty-plus years ago. The dinosaur tracks are very clear, but the human tracks are what today we would call “fake news.”

The area near Glen Rose, Texas, has been in a drought, and some of the Paluxy River dried up, exposing the new tracks. There are now five dinosaur track sites in the park. The tracks show the depth that the animal’s feet sank into the mud, which was part of a beach area in the dinosaur age. The depth of the tracks and how far they are separated from each other suggest that the animal was bipedal and very large. Researchers say that the dinosaur was an Acrocanthosaurus.

Some have claimed there are dinosaur tracks and human tracks in the same rock layer, attempting to prove that dinosaurs and humans lived at the same time. However, the claimed human tracks are impressions in mud that were altered by the river and then painted by those who claim they are valid. They also sink the same depth into the ground, suggesting that the “humans” were the same weight as the dinosaur, which is impossible. Furthermore, researchers have found no human tracks anywhere in the same rock layer as dinosaur tracks.

We have suggested that dinosaurs were part of Genesis 1:1 and God used them to prepare the resources humans would need. Dinosaurs are not described in the Bible because the ancient Hebrews could not have comprehended their existence. People who believe the Bible must be careful not to employ the same fake news techniques frequently used in politics. Claiming that dinosaur tracks and human tracks prove that they lived simultaneously is a dispensational denominational religious view the Bible does not teach.

God’s word is true, but we must rely on valid evidence as we seek to support it as a guide to understanding history and knowing how to live our lives.

“Terrible Lizards” or Dinosaurs

Tyrannosaurus Rex was one of the Dinosaurs or “Terrible Lizards”
In the final days of 2022, we are looking back at some of the major topics we have previously covered.

People are always curious about dinosaurs. These dinosaurs, or “terrible lizards,” are much more than ancient animals that fascinate children. Most adults also find them fascinating and can name some dinosaur genera. (For example, Tyrannosaurus, Triceratops, and Megalosaurus.) Dinosaur paleontologists are constantly discovering and naming more dinosaurs until we now have more than 900 known species in more than 300 genera. People want to know when the dinosaurs lived and if there were any people around when those dinosaurs or “terrible lizards” roamed planet Earth. Here are some links to previous discussions on the topic of dinosaurs:

Our understanding of dinosaurs brings up the questions people are always asking about the age of the Earth. We have dealt with that before and will have some links to that topic tomorrow.

Nadir Asteroid Impact Crater

Chicxulub and Nadir Asteroid Impact

One of the challenges to evolutionary theory is the principle of uniformitarianism–the assumption that no process has ever functioned on Earth that is not going on today. We are not talking about common disasters but events in Earth’s history that would have altered the course of evolution or stopped it entirely. For many years, scientists have known about the Chicxulub asteroid that struck the area that is now Mexico’s Yucatan Peninsula, probably causing the extinction of the dinosaurs. Such an event would have changed life’s future direction. Now, there is news of a Nadir asteroid impact crater.

BBC news reported that geologists discovered a possible asteroid crater off the coast of Guinea in west Africa. They call it the Nadir crater because it is at the Nadir (opposite lowest point) of the Chicxulub crater. This new crater is 8,500 meters wide and over 300 meters lower than the seabed. It is about the same age as Chicxulub but much smaller. The Chicxulub crater, caused by a larger asteroid, is 12,000 meters wide.

Both of these asteroid collisions would have violated uniformitarianism, dramatically affecting life on Earth. The Chicxulub asteroid impact would have caused major earthquakes, tsunamis, and a global firestorm. The result would have thrown enough dust into the atmosphere to plunge Earth into a deep freeze that dinosaurs could not have survived.

Since the Nadir asteroid impact crater is in an ocean environment, it would have caused a tsunami with a wall of water over 1000 meters high. The Nadir collision would have produced about 1,000 times more energy than Tonga’s recent (January 2022) volcano eruption. However, the energy from the Chicxulub impact would have been about 10 million times greater.

The textbook model of evolution is greatly simplified. We don’t fully understand how an asteroid collision would have affected life on Earth. It seems unlikely that most life forms could have survived the one-two punch of Chicxulub and Nadir asteroid impacts.

Genesis 1:1-3 indicates that there was a change in the Earth. An accurate translation of verse 2 is that Earth “became empty and wasted.” That is precisely what the asteroid collisions would have caused. This may have been God’s methodology of a final step to make Earth fit for human life. This new evidence supports the biblical account in ways we are only beginning to understand.

Oxygen and Nitrogen Levels in the Atmosphere

Oxygen and Nitrogen Levels in the Atmosphere

Oxygen and nitrogen are two of a handful of elemental superstars of life. Without them, life would not be possible. In some ways, these two elements are very similar, but they are also very different.

Oxygen and nitrogen atoms differ in only one proton and one electron. In chemical reactions, the important subatomic particle is the electron, and oxygen has eight while nitrogen has seven. In the last two days, we talked about the difference that one electron makes. Oxygen and nitrogen make up about 99% of our atmosphere, with nitrogen composing nearly three-quarters of our air. So why is nitrogen’s percentage so high compared to oxygen?

As we said previously, the triple bond of a nitrogen molecule requires more than twice as much energy to break as the double bond of an oxygen molecule. The oxygen bond can be broken to allow combustion oxidation and energize our bodies. On the other hand, the nitrogen bond is not easy to break, but plants require nitrogen for photosynthesis and growth. What is the solution?

Lightning breaks the nitrogen bond allowing rain to wash nitrogen to the ground. Plants such as beans, peas, and alfalfa, which we call legumes, have microorganisms on their roots that extract nitrogen from the air. That enriches the soil with nitrogen while providing for the legumes. More than a century ago, scientists found a way to extract nitrogen from the air to produce ammonia. That process enabled fertilizer production, which today allows farmers to produce enough food for the world’s population.

It is not easy to break the nitrogen bond so it can combine with other elements, but with 78% of the atmosphere being nitrogen, there is no shortage. So why is our atmosphere mostly nitrogen? Since it is only about 21% oxygen, wouldn’t it be better to have more oxygen so we could breathe easier? The answer is that nitrogen stability is essential for our safety. Wildfires have been a significant problem in recent years. If the atmosphere consisted of a very high percentage of oxygen, fires would be more common and dangerous. If the atmosphere consisted of 100% oxygen, all it would take is one lightning strike to set the whole planet on fire.

Remarkably, we have the correct percentage of elements in our atmosphere. We have the right amount of oxygen to allow respiration to power our bodies and combustion to power our vehicles and industry and heat our homes. At the same time, we have the right amount of nitrogen to prevent uncontrolled combustion leading to the destruction of life. We have just a small amount of carbon dioxide, which plants need for photosynthesis. Plants use CO2 and generate oxygen to keep the gases in balance. The balance is amazingly precise as long as humans don’t generate enough carbon dioxide to mess it up.

During the dinosaur age, the oxygen level was higher, on the order of around one-third of the atmosphere. That allowed the enormous animals to prepare the Earth for humans. Now we have the precise balance to sustain human life and advanced society. The question is, did the features of oxygen and nitrogen and the balance between them happen by accident, or was it part of an intelligent plan? We think the best explanation is that an intelligent Planner of life created it.

Mesozoic Era Small Animals

Mesozoic Era Small Animals are not displayed in Dinosaur Valley State Park
Dinosaur Valley State Park in Glen Rose, Texas

What most people know about the dinosaurs is what they have seen in a movie or a museum. The emphasis is always on the massive size of these ancient animals. Those of us with a background in paleontology are more interested in the ecosystem in which they lived. The Mesozoic era was a time when the Earth was very different from what it is today. It appears that the oxygen content of the atmosphere was higher, and the temperature was much warmer. The plants and animals living at that time enjoyed a balanced ecosystem that left a legacy that has allowed us to live comfortably on this planet.

The natural resources humans have depended on for our entire history were produced during the Mesozoic era. These include coal, oil, and a wide variety of soils that allow our modern plants to exist. From a biblical standpoint, this was a part of Genesis 1:1 when God prepared the Earth for what was to follow. For more on this, see “God’s Revelation in His Rocks and His Word” on our doesgodexist.org website. (You can purchase printed copies HERE.)

What many people don’t realize is that while the giant dinosaurs were an essential part of the Mesozoic era ecosystem, small creatures were of equal importance. Insects were a significant part of the system, and fossil remains of all kinds of arthropods are abundant in the fossil record. As we all know, insects can reproduce in destructive numbers. Just as there were meat-eating dinosaurs to keep the plant-eaters from destroying all the vegetation, there were insect-eaters to control the insect populations. We have insect swarms like the locusts that are causing massive problems in Africa today because humans are removing the natural controllers of insect populations.

The recent discovery of a creature named Oculudentavis khaungraae has shown us a dinosaur the size of a bee hummingbird, the smallest known modern bird. This dinosaur’s skull was half an inch from front to back, and it had a mouth full of teeth. It was ideally suited for eating insects of all kinds and sizes and was undoubtedly a vital part of the ecosystem during the Mesozoic era of the dinosaurs. God has always used one existence to prepare for another, and the preparation of the early Earth for humans was a long and highly complex process.

Our existence on Earth is also a preparation for a far better one. Continuing to study God’s creation and His Word helps us prepare for that time when we will exist outside of space-time. Read about it in Revelation 22:1–5.
