The Shrimp and the Urchin

The Shrimp and the Urchin

The oceans host many symbiotic relationships. In symbiosis, plants and animals live together in ways that benefit them and often others nearby. This is the story of the shrimp and the urchin.

Coleman shrimp (Perclimenes colemani) eat parasites they take from fish that come close to them in the western Pacific Ocean. These shrimp were not discovered until 1975, perhaps because they blend in very well with the sea urchins with which they have a symbiotic relationship. The picture shows the spotted body and striped legs of the Coleman shrimp surrounded by the striped tube feet of the fire sea urchin (Asthenosoma varium).

Coleman shrimp are known as cleaner shrimp because they remove parasites from fish. Most cleaner shrimp live in sea anemones, but Coleman shrimp prefer to live in fire sea urchins. The venom-tipped spines of the fire urchin do not harm the Coleman shrimp, and they protect them from potential predators. Meanwhile, fish infected with parasites approach the Coleman shrimp to have the parasites removed. The parasites are food for the shrimp, and the fish don’t eat the shrimp or the fire sea urchin because of its poisonous spines.

We see a balanced symbiotic relationship among various species of ocean creatures. The shrimp and the urchin, along with many fish that benefit, are just some examples of symbiosis—where different plant and animal species depend directly on each other. In many cases, a species could not survive without this mutual relationship. This is another sign of design in living creatures, and design points to a Designer.

Origin-of-Life Theories and Archaea

Origin-of-Life Theories and Archaea

Scientists aim to answer several very difficult questions about origins. Two of these questions relate to the origins of life and complex life. Some scientists believe they are getting closer to discovering how complex life developed from simple life, and the media often sensationalizes any origin-of-life theories.

Living things are classified into three domains. We are very familiar with multicellular life, which includes plants, animals, and people. That is the domain of eukarya, or complex life. There are two domains of single-celled life—bacteria and archaea. Most people are more familiar with bacteria than archaea. Scientists did not recognize how distinct archaea are from bacteria until the 1970s, when DNA analysis began.

The cells of bacteria and archaea are relatively simple and small compared to eukaryotic cells, which have a nucleus, mitochondria to supply energy, and other internal structures. In the 1960s, one group of microbiologists described the gap between eukaryotes and the single-celled bacteria and archaea as “the greatest single evolutionary discontinuity to be found in the present-day world.” Evolutionists seeking origin-of-life theories had to find a way to bridge this very wide gap.

In 2008, researchers discovered a new type of archaea living in hydrothermal vents on the Atlantic Mid-Ocean Ridge. They said these archaea “seemed to be somehow closer to eukaryotes than what we knew before.” In 2015, a paper published in the journal Nature described them as “the closest known living relatives of eukaryotes,” creating a scientific sensation. Their genomes were said to contain genes that are “hallmarks of eukaryotes.”

Scientists theorized that the Asgard archaea, as they came to be called, absorbed bacteria that became mitochondria, but there was still no evidence of a nucleus. Research and debate on this are expected to continue for years, but it has sparked new speculation about extraterrestrial life. Some have suggested that unicellular life on other planets could evolve into eukaryotic, advanced life. But that assumes there is unicellular life on other planets.

Scientists proposing origin-of-life theories still have no idea how non-living matter could turn into living, reproducing cells. Be cautious when you see media stories about scientists being close to discovering the origin of life or the origin of complex life. Even simple cells are far too complex to have arisen by chance without a Designer.

Tiny and Incredible Shrews

Tiny and Incredible Shrews

You may not have seen them, but thousands of shrews scurry across the ground, helping keep your garden free of destructive insects, snails, and slugs. Tiny and incredible, shrews are North America’s smallest mammals. They are smaller than a human thumb and have hearts that beat 1,200 times per minute.

There are 39 shrew species in North America, and many more worldwide. There is even one that can walk on water thanks to stiff hairs on its feet. That species feeds underwater using bubble sniffing—a technique of blowing small air bubbles through their noses to detect odor particles in the water.

Shrews are not rodents but insectivores, similar to hedgehogs. Their coat helps them camouflage amid leaf litter and debris. They have scent glands on their sides that emit a foul odor to deter predators such as cats, raccoons, and foxes. Like bats, they can use echolocation to find food.

A shrew’s metabolism is so high that it must eat roughly once an hour, and it only sleeps for a few minutes at a time. Though they don’t hibernate, they make tunnels beneath snow or ice layers. One remarkable trait of the tiny and incredible shrews is that they can actually shrink their head size, including their brains, by 20% during cold weather. Since food becomes scarcer in winter, shrinking their heads and brains helps them require less food. Their head size returns with warm weather.

Shrews are among God’s most useful creations because they help control snails, slugs, insects, and ticks, protecting plants and people. Only in recent years has technology enabled us to study the tiny and incredible shrews.

Pseudoscience, True Science, and Faith

Pseudoscience, True Science, and Faith

This website is dedicated to promoting science and faith as allies. Many people in religious communities believe that science opposes faith because of their denominational teachings that conflict with scientific evidence. The faith of many young people and members of the academic community has been weakened or broken by the ongoing clash between science and faith. Often, pseudoscience is the root cause of this conflict. Here are five reasons for the tension:

1) Some of the conflict’s promoters are religious leaders with no scientific background or understanding.

2) Many of the individuals claiming to be scientists hold PhDs in fields unrelated to the issues they discuss.

3) Some scientists harbor resentment against religion and refuse to support supporting evidence.

4) Many individuals on both sides are outdated and unaware of new discoveries and insights.

5) The viewpoints of both scientists and religious leaders are not reliable sources of information.

Webster’s Dictionary defines “pseudoscience” as “a collection of beliefs or practices mistakenly regarded as being based on scientific method.” Those promoting the conflict between science and faith are promoting pseudoscience. We urge parents, teachers, religious leaders, and young people to verify everything they read, hear, or see to ensure its accuracy.

This ministry strives diligently to avoid presenting anything that could be mistaken for pseudoscience. When we make an error, we issue a retraction. Our sources are academic journals that rely on the scientific method. In 1 Timothy 6:20, the Apostle Paul advised the young preacher Timothy to “turn away from godless chatter and the opposing ideas of what is falsely called science.” That advice remains especially relevant today.

Horns and Antlers – What Are They Good For?

Horns and Antlers – What Are They Good For?

Ronald Johnson asked us a question we’ve heard from animal rights advocates before. Are horns on animals only useful for fighting, showing God to be war-like, angry, and sadistic? The God of the Bible is a loving, caring, merciful, and patient God. When there is violence, killing, and war, the cause is always human power struggles and selfish motives, not the will of God. So, what other purposes do animal horns serve? Here are four non-violent uses for horns and antlers:

1) Horns act as shovels that help animals access food sources they otherwise could not reach. Vegetation is often either too high or too far underground for many animals to reach. Horns allow animals to break off hard-to-reach vegetation or move logs or rocks to reach food sources.

2) Antlers store nutrients that other animals recycle. Many animals, birds, and insects eat discarded antlers to get the extra nutrients they contain.

3) Horns and antlers are used as communication tools with other animals of their kind. Those of us who spend a lot of time in the woods have seen “deer rubs.” This is when a deer uses its antlers to scrape a mark on a tree, signaling its presence, size, and how long ago it was there to other deer.

4) Horns serve as shields against predators like hawks, eagles, falcons, wolves, bears, lions, hyenas, tigers, cheetahs, dogs, and other carnivores. The animal with horns can protect itself and others nearby. I have seen musk oxen defend their young by forming a ring around them with all the horned animals facing outward. A pack of wolves circled the group but never tried to attack.

Animals certainly have other uses for horns and antlers, but the main point is that in most animals, they are rarely used for fighting. God has provided all living things with what they need to live on our planet, and we can see His wisdom and design in the things He has made (Romans 1:20).

Healthy and Unhealthy Food

The Bible clearly shows how God provided food for humans. Genesis 2:8-9 explains that God planted a garden in Eden where He placed the first couple, and “the Lord God made all kinds of trees grow out of the ground–trees that were pleasing to the eye and good for food.” Today, we have a choice between healthy and unhealthy food.

In Genesis 9:3, God tells Noah, “Everything that lives and moves will be food for you. Just as I gave you the green plants, I now give you everything.” Later, God forbade the eating of animals that carry disease, like vultures, and prohibited drinking blood, but what God created for humans to eat is quite clear and beneficial.

In recent years, humans have created foods that are not healthy. Some seasonings may improve flavor, but they can be unhealthy. This leaves us with a choice between healthy and unhealthy food. The worst offenders include salt, refined sugar, ethyl alcohol, and animal fat. Science shows that these cause vascular problems and excessive weight gain. Increasing evidence links diet to mental health issues, memory problems, heart problems, kidney failure, and sexual dysfunction.

All of this strongly supports the Bible’s inspiration. When you see how accurate biblical instructions about what humans should eat are, it’s hard to see that as a coincidence. The negative effects of an unhealthy diet often appear long after the bad food is eaten. God created good food to meet human needs, but, as with everything else, negative consequences often result when humans modify what God has provided.

Helicopters and Dragonflies

Helicopters and Dragonflies

Igor Sikorsky is recognized as the father of the modern helicopter, but what may not be as widely known is how he gathered the information that led to its development. This is the story of helicopters and dragonflies.

Sikorsky dedicated years to observing birds and insects to understand how to achieve stable, controlled flight. Dragonflies stood out because their wings operate independently, each capable of rotating, tilting, and shifting angles to produce quick changes in lift.

As helicopter technology has advanced, engineers continue to draw inspiration from the dragonfly. Its sideways dashes, backward flight, sudden stops, and precise hovering are still studied by engineers. Even the dragonfly’s timing patterns, rotational wing strokes, and quick lift adjustments have been emulated to improve the stability of helicopter rotor systems.

Dragonflies offer a blueprint for aerial agility, and their design is an engineering marvel. The big question is how the dragonfly’s design came about. It seems impossible to explain this complexity as the result of random chance. It appears to be a design from a Master Engineer.

Helicopters and dragonflies serve as another example of biomimicry and provide evidence that all life is a product of intelligence, demonstrating the truth of Romans 1:20 that we can know there is a God through the things He has made. as made.

Evidence for the Existence of a Creator in the Big Bang

Evidence for the Existence of a Creator in the Big Bang
Big Bang Timeline

Cosmology offers compelling evidence for the existence of a creator God. Many people in both religious and skeptical communities see the Big Bang theory as a threat to the credibility of the Genesis account and the existence of God. However, this is unfortunate because the Big Bang theory actually aligns with the Genesis account and presents a cause of creation that skeptics cannot explain.

Technology has confirmed the Big Bang. The Cosmic Microwave Background (CMB) provides the oldest record of the universe’s temperature and density from the very beginning. The latest CMB data show that the universe began with a hot Big Bang. Data from the Wilkinson Microwave Anisotropy Probe verify that time started at the Big Bang.

The words of Genesis 1:1 fully correspond to this data. The first word in the Bible is “reshith,” meaning an absolute starting point. The next word refers to God, followed by “bara,” a term used exclusively for acts only God can perform. Then, we see the word is “shamayim,” meaning “heaved-up things.” The rapid expansion of the universe aligns perfectly with this wording.

Further study of the biblical record reveals the ongoing battle between good and evil and God’s creation of humans through whom that battle occurs. (See Job 1 and 2.) Skeptics cannot explain why humans exist. The greatest failure of atheism is that it offers no reason for the existence of the cosmos or human life. When science and religion conflict, it often indicates either poor science, poor religion, or both. Historically, this has been the case with the Big Bang theory, but as science progresses and people deepen their understanding of what the Bible truly teaches, we see that both science and Scripture provide strong evidence for the existence of a Creator.
