Endothermic or Ectothermic – What’s the Difference?

Endothermic or Ectothermic – What’s the Difference?

You are an endothermic mammal. That means your body’s metabolic rate controls your internal body temperature. We describe that condition by saying you are “warm-blooded.” Many life forms on our planet are “cold-blooded” (ectothermic) because the environment controls their internal body temperature. The limitation of being cold-blooded is that it requires warm environmental temperatures. Ectothermic life forms can’t survive in polar areas. Endothermic life can survive almost anywhere.

During the time of the dinosaurs, the planet was very hot. That means biological systems, including plants, grew quickly. Those conditions were part of God’s preparation of resources that humans would need, including oil, coal, topsoil, and oxygen. However, the geologic record shows a point in Earth’s history when the climate radically changed. 

As the entire planet cooled, areas at or near the poles became too cold for cold-blooded life to exist. Studies of bone growth rates and oxygen isotopes in ancient bones indicate a rapid change. This change would not be a problem for warm-blooded animals but would reduce the number, size, and activity of cold-blooded life forms.

The challenge would be to design living creatures that can translate food into enough internal heat to survive in a cold environment. Science News reported on studies of the inner ears of reptiles and mammals. In warm-blooded animals, the inner ear fluid is less viscous, requiring that the ear canals become smaller. As a result, fossils show a sharp change in inner ear morphology at the time when Earth’s climate became colder. 

Many other changes were required for life to go from ectothermic to endothermic. However, the inner ear structure is preserved in the fossils, making it useful for scientists to study the history of life on Earth. The complexity of endothermy reminds us again of the words of Psalms 139:14, “I will praise you, for I am fearfully and wonderfully made: marvelous are your works.” In our time of changing climate, the design of life continues to show the wisdom involved in life’s creation.

Where Do We Find Dinosaurs Mentioned in the Bible?

Where Do We Find Dinosaurs Mentioned in the Bible?
Barosaurus Illustration

Yesterday, we pointed out that words like “behemoth” in the original language of Genesis 1 would not have included animals like dinosaurs but referred to animals the ancient Israelites knew. So the next logical question would be, “Where do we find dinosaurs mentioned in the Bible?” The answer to that question is “nowhere.”


Why would the Bible mention dinosaurs? Consider how you would explain bacteria to a man with no microscope, or how could a person living in the jungle make sense of an octopus? When an explorer brought a stuffed platypus back to England for the first time, people thought it was a fake. Millions of different plants and animals have lived on Earth, and many of those still exist today. The purpose of the Genesis account is to say that God created everything, not to identify the millions of species that have lived on Earth. Genesis mentions only the animals the Israelites could identify and name.

So from today’s perspective, when did those animals exist? Some fundamentalists have suggested that we don’t find dinosaurs mentioned in the Bible because they didn’t exist. They say that God miraculously created dinosaur fossils to give the appearance that the animals lived when they did not. That explanation makes God a liar trying to fool us into a false conclusion.

Others suggest that dinosaurs were there but simply weren’t mentioned in the Bible.
There is no evidence that animals like T-rex lived at the time of Adam and Eve. In reality, the atmosphere and temperatures necessary for such an animal to survive would be detrimental to humans.

Since we don’t find dinosaurs mentioned in the Bible, what was God’s reason for creating these huge animals? God knew that humans would need an environment optimized for their survival. In Alaska today, the survival of various life forms depends on salmon bringing nutrients into an environment lacking those essentials to support life. Like the salmon, the dinosaurs were the vehicles that provided resources needed for humans to exist and flourish later. The plant-eating dinosaurs consumed massive amounts of vegetation and excreted processed plant materials and seeds. They spread the vegetation and produced topsoil and critical elements necessary for human life. No animal living today could accomplish that task.

When Genesis 1:1 tells us that God created the heavens and the earth, the result would be a functioning universe and a dynamic planet where humans could eventually live. Earth was not a blob of molten rock or hydrocarbons but a functional planet, and dinosaurs were one of the tools God used to prepare it for humans. The big animals and plants helped create topsoil, coal, and a variety of trace elements human life would need. The oceans nurtured diatoms that produced the massive amounts of hydrocarbons humans would need for oil and gas. We don’t find bacteria, diatoms, or dinosaurs mentioned in the Bible because they are included in Genesis 1:1.

God could have zapped the hydrocarbons into existence, but if He had done it that way, humans could never have located them. God not only created the resources we would need, but He did it in a way that we could find them. He gave us the intelligence to study His methods to find the resources and obtain them for our use.

The wisdom of God in designing Earth to sustain human life is incredible. Every day, science finds new clues about how the planet was designed and how things we might consider insignificant are critical to our existence.

Diversity of Life on Earth

Diversity of Life on Earth

We read reports of scientific research from all over the globe. Scientists are discovering how various forms of life exist on this planet. There is a diversity of life on Earth, even in environments where you wouldn’t expect life to survive.

One such environment is in the deepest part of the ocean, where animals must live in total darkness. The design that enables them to survive with no light from the Sun or Moon is bioluminescence. These animals generate their own light so they can find each other and locate prey. There is a whole chain of life in the darkness of the deep ocean, and we are learning that this ecosystem absorbs greenhouse gases that affect the atmosphere for land creatures.

We see this kind of balance in oceans of the past. Long ago, sea animals were large enough to maintain balance in the sea by eating tremendous quantities of food. For example, a marine reptile carnivore known as ichthyosaur was up to 66 feet (20 meters) long. When the asteroid strike wiped out the giant creatures, including the dinosaurs and ichthyosaurs, the smaller life forms survived and established a new food chain.

Scientists are discovering unique designs that enable animals to survive what would appear to be impossible conditions. For example, how can a boa constrictor breathe as it squeezes the life out of prey and ingests it? Why doesn’t the act of compression force the air out of the snake, suffocating it? The answer is that boas have 200 pairs of ribs and some of the ribs squeeze the prey while others are designed to allow the snake to breathe.

The diversity of life on Earth allows specialized equipment designed for living in any environment. Even humans are diverse. Modern pygmies are well-designed to live in a jungle environment. Fossils of a hominin named Homo naledi tell us that ancient small humans existed in environments with fewer resources. Most of what we know about them comes from a burial chamber found in a cave in South Africa.

We see the diversity of life on Earth today, even in humans able to survive in challenging environments. Racial characteristics in humans offer survival benefits in the diverse habitats of our planet, and they are not a basis for discrimination. We need to understand that diversity in animals and humans is an expression of God’s wisdom and design for life everywhere on Earth.

An Overlooked Role of Birds and Mammals

An Overlooked Role of Birds and Mammals

Various data sources show massive evidence of climate change. The melting of the ice sheets, the warming of the Pacific Ocean, and the increase of weather anomalies affect all of us. Some of these changes have to do with flooding and the frequency of storms. Others affect our food supply where there is an overlooked role of birds and mammals.

While the effect on human activity is pretty dramatic, the natural changes in living things in the environment are usually less noticeable. The reason is that the design of life anticipates that climate will change from time to time, even if humans have no role in that change. If a plant species faces environmental change threatening its existence, it will disperse its seeds into a different place where the environment is more suitable.

The often overlooked role of birds and mammals is that they are the primary agents for seed dispersal. The National Science Foundation helped fund a study showing that more than half of all plant species rely on animals to disperse their seeds. The NSF website said, “Plants that rely on seed dispersers can face extinction if there are too few animals to move their seeds far enough to keep pace with changing conditions.”

One of the things that plant-eating dinosaurs did was
to spread the seeds of the plants they ate. This means that pruning was not the only benefit of plant-eaters, but seed spreading was also significant. As the climate has changed in the past, animals have spread the seeds over a vast geographic area allowing the incredible diversity we see in plants today.

This kind of research has a variety of practical uses.
It reminds us of the overlooked role of birds and mammals in dispersing seeds in the environment. The study showed a 60% reduction due to the loss of seed-spreading birds and mammals.

We see evidence of God’s wisdom in designing birds and mammals with a diet that allows spreading the seeds of the plants they eat. That design helps to moderate the effect of climate change. God told Adam and Eve to take care of the Garden (Genesis 2:15), and we need to understand our responsibility in that. The fact that creation’s design allows life to survive climate changes is a testimony to God’s wisdom.

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.

A Larger Dinosaur Has Been Found

A Larger Dinosaur

We are amazed by the enormous size of animals in the distant past. From a giant millipede to the Titanoboa and the Titanosaur, the size of ancient animals excites fossil hunters. Since 2017, Patagotitan has held the record for the largest dinosaur at 120 feet (36.5 m) long and weighing over 57 tons. However, paleontologists in Argentina recently found pieces of a larger dinosaur.

The size of this animal has several implications. First, we need to be reminded that, unlike mammals, reptiles never stop growing, so there is virtually no limit to their size. A more significant issue is having environments warm enough for such animals to live and enough plant material to sustain them, plus a high oxygen level.

The environment that allowed a larger dinosaur to survive would not have been hospitable to mammals. Reptiles can not only survive very hot conditions, but they require heat to sustain their bulk. A hot Earth with very wet conditions would also promote rapid plant growth. Accordingly, the plant fossils from the time of those animals indicate huge size and rapid growth.

The Bible makes clear that everything humans would need to live on Earth was produced before humans were created. Therefore, we have maintained that God was not a magician miraculously zapping things into existence. God could do the creation any way He wished, but He wisely chose to make the resources humans would need in such a way that we could find them.

God acted as an engineer, producing the coal, gas, oil, iron, salt, and other resources we would need by processes we can study and understand. The volume of fossil fuels stored up for our use is a staggering number. Present-day processes on Earth could never produce them, but the enormous animals and plants of the past created enough resources to take us into the nuclear/solar age.

The Bible tells us that God created planet Earth, not how or how long He took to do it.
Genesis 1:1 is not dated or timed. However, as we look at the record of the past, we see God’s wisdom and power and the magnitude of the creative process that allows us to exist.

Rather than trying to fit a larger dinosaur into Noah’s Ark, we need to take Genesis for what it says and not add denominational traditions. We must not use the economy of language in Genesis to justify our human religious theories.

The Purpose for the Woolly Mammoth

The Purpose for the Woolly Mammoth

Often when we see fossil evidence of extinct animals, we wonder what purpose that animal served. For example, the giant plant-eating dinosaurs not only pruned the fast-growing plants of the world in which they lived, but they also spread the plant seeds and fertilized the ground where the plants grew. So what was the purpose for the woolly mammoth?

Russian researchers have found that woolly mammoths played a significant role in shaping the Siberian tundra in the ancient past. Today we see that massive amounts of moss dominate the terrain and causing a build-up of carbon dioxide. Woolly mammoths pulverized the moss, clearing the way for grass to spring up. They enriched the soil for the grass to grow, and the grass stopped soil erosion and took in carbon dioxide.

An American company wants to reconstruct the woolly mammoth’s genome and create herds of woolly mammoths to repeat what happened in the past. That company believes they can increase grass growth and create a whole industry based on herds of woolly mammoths.

This scenario sounds similar to the theme of the movie Jurassic Park. Unfortunately, we don’t have good information about what woolly mammoths were like, how they lived, and what diseases they carried. God had a purpose for woolly mammoths, and the research by the Russian scientists tells how that system worked in the past. When humans try to duplicate what God did, they usually do more damage than good.

An Asteroid and Snakes

An Asteroid and Snakes

There is an interesting connection between an asteroid and snakes. Evolutionists have often believed in uniformitarianism–the idea that no process has shaped planet Earth in the past that is not going on today. The problem with uniformitarianism is that a great deal of evidence shows that it’s not true. The most accepted example is that when dinosaurs ruled the planet, an asteroid strike caused a mass extinction of 76% of all plant and animal life.

A research study by the University of Bath in England has shown that one form of life did well through and after the asteroid collision. That life-form was snakes. There were small snakes before the asteroid strike, but large snakes were easy prey for dinosaurs and simply did not survive. After the asteroid collision, small snakes hid underground and survived for a time without food.

When the snakes emerged, they didn’t face competition from other animals. With their newfound freedom, they spread throughout the world. Today, snakes live on every continent on Earth except Antarctica. Catherine Klein, the lead researcher in examining the snake fossil record, has shown that large snakes did not appear again until all the dinosaurs were gone. She told the BBC, “It’s likely that without this asteroid impact, snakes wouldn’t be where they are today.”

The evidence for the asteroid collision grows every year, and it comes from many different disciplines. Uniformitarianism is not true, and yet a gradual evolution of all life depends on it. Evolution would have to start over after events like the asteroid strike that wiped out massive amounts of life on the planet.

You have probably never thought of a connection between an asteroid and snakes. Current theories of evolution have significant problems with a lack of positive evidence and a growing amount of counter-evidence. God works in mysterious ways, and sometimes He has used catastrophes to shape the Earth for human existence.

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.

How We Use Our Money

How We Use Our Money - $32-million To buy a T. rex fossil?

One of the interesting things going on in the world today is how we use our money. The sale of a T. rex fossil is one example. The skeleton of a massive dinosaur can bring huge profits to the owner. Recently a 13-foot tall Tyrannosaurus rex fossil known as “Stan” was sold at Christie’s Auction House for $32,000,000. Most of us would wonder why anyone would spend that kind of money on a fossil? Sarah Rose Sharp gave a possible answer in Hyperallergic.com:

“And honestly, can we find a more contemporary symbol than a tyrant king who stomps on all other living things with no regard for propriety, before witnessing the extinction of his species based on natural science beyond his control?”

Daily we see reports of leaders in politics, media, and technology raking in vast amounts of money no matter who gets hurt in the process. Jesus dealt with this mindset in His day. The parable Jesus told in Luke 12:16-21 is a picture of what is happening today. We should heed His follow-up teaching in verses 22-34. The words of Jesus in Matthew 6:19-21 tell us what we should hold as important. Luke 18:10-14 demonstrates the attitude we should have.

The sale of a dinosaur fossil for massive amounts of money is just one more illustration of how we use our money and where we place our priorities.
