Heart Cockle Fiber Optics

God has equipped all living things with some method of survival. Research on the heart cockle, a small clam that lives in shallow waters in the Indian and Pacific oceans, has shown that it uses fiber optics to get sunlight through its shell to supply the food it needs.

Heart cockles get their food from algae living within their shells in a symbiotic relationship, benefiting both parties. The algae get sunlight through a crystalline form of calcium carbonate called aragonite arranged in tiny tubes that function like fiber-optic cables. These tubes allow visible light to pass through the cockle’s shell while blocking infrared and ultraviolet light. The algae use the light to produce sugars and other nutrients that benefit the clam while the clam protects the algae within its shell.

According to Science News, the aragonite can channel light without the reflective coatings that telecommunications fiber optics require. While filtering out harmful ultraviolet light, the fiber optic-like structures are “finely tuned to balance the shell’s mechanical strength with its ability to efficiently transmit light.” The “finely tuned” heart cockle shell design had to have a designer, and trying to explain it by chance alone requires a vivid imagination. This is one more evidence that God has designed a vast number of ways for life to survive.

The Fear of Snakes

Everything in existence had a reason to be created, even snakes. There are over 3600 species of snakes, and roughly 725 of them are venomous. However, only about 200 species can harm or fatally injure a human with just one bite. The fear of snakes is common. Snakes vary in size, with the smallest being the Barbados thread snake, which grows to a maximum of roughly 4 inches. The largest found so far is a reticulated python, 23 feet long and weighing over 215 pounds.

So, why are people afraid of snakes? Movie watchers may remember the scene in “Raiders of the Lost Ark” when Indiana Jones looked over ruins and saw the floor was covered with snakes. He muttered, “Snakes, why did it have to be snakes!” The fear of snakes predates Indiana Jones. Many Bible passages involve snakes. When Moses threw his stick on the ground in Exodus 4:1-3, it became a snake, and Moses ran from it.

Why do snakes exist, and what lessons do they have for us? First, on a scientific level, snakes are incredibly well-designed to eat warm-blooded pests. They smell by using their forked tongues to collect airborne scent particles. They deposit those particles on special organs called vomeronasal or Jacobson’s organs on the roof of their mouths. In addition, snakes have nerves on their underside, which are very sensitive to vibration. These features enable snakes to go into a burrow and remove a rodent that would otherwise be a pest to humans. Snakes are rarely aggressive. They bite when someone invades the snake’s territory or deliberately antagonizes it.

In Mark 16:17-18 Jesus speaks about snakes as He describes His followers: “…they will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick, and they will recover.” Some denominations have handled snakes as a part of their worship service. This display of bravado is not what Jesus was talking about. At the time Jesus spoke, there were no scriptures to allow a person to whether or not a messenger was from God. Jesus said his messengers would be fluent in many languages and able to handle snakes, drink poison, and heal the sick 100% of the time. None of the current “snake handlers” can do all of those things. We learn from 1 Corinthians 13:8 that those things are unnecessary after God’s perfect word became available.

In Genesis 3:1-4, was Eve dealing with a talking snake? Was the curse on the snake in verses 14-15 to crawl for future generations? Looking at all these verses, it seems that the message is spiritual and involves offspring. You can see that in the highly symbolic contrast between crushing the head and striking the heel. The theological debate on these questions has gone on for thousands of years.

Despite the fear of snakes, the bottom line is that snakes serve humans in marvelous ways. They should be respected rather than feared. Genesis reminds us of Satan’s power and the importance of living as God has told us to.

Wildlife in Winter and Conifers

Wildlife in Winter survive because of conifer forests

Winter presents new challenges for all of us, but God has made unique provisions for wildlife in winter. One of the most interesting is the conifers and what they provide for birds.

Winter does not threaten northern birds because all the food and shelter they need is available in four conifers. Berries last through the winter on winterberry holly, Virginia creeper, and trumpet honeysuckle. Cedars have cones and attract insects like carpenter ants that birds eat. Cedar waxwings, golden-crowned kinglets, and pileated woodpeckers thrive on Cedars. Spruce trees have seeds that feed evening grosbeaks, fox sparrows, and juncos. Fir trees provide for nuthatches, chickadees, and spotted owls. Birds can open the cones of white pines to eat the seeds, with nutcrackers and crossbill finches being the most adept.

Conifers exist virtually everywhere on planet Earth, which means bird habitats are available everywhere. The survival of wildlife in winter is possible for birds, other animals, and the plants they depend on. While tropical areas might seem ideal for birds, winter offers freedom from most parasites and provides a host of food and shelter sources. Conifers grow at high elevations and high latitudes where other plants could not exist.

There is amazing diversity everywhere we look on our planet, providing a great testimony to the wisdom and design God has put into His creation. Genesis 8:22 indicates that summer and winter are built into the creation, and Psalms 74:17 tells us God is the creator of summer and winter. As we look outside here in Michigan, we see many birds thriving despite the snow and ice. The survival of wildlife in winter is based on the protection they have from the cold and the food that is readily available to birds in the conifers.

The Value of a Dinosaur Fossil

What is the value of a dinosaur fossil? In 2024, the current record price for a fossilized dinosaur skeleton is $44,600,000 paid for a Stegosaurus fossil nicknamed Apex. The fossil, found in Colorado in 2022, is 27 feet long and 11 ½ feet tall. Kenneth C. Griffin, who bought the Stegosaurus fossil, is loaning it to the American Museum of Natural History in Manhattan, which expects millions of visitors to come and see it. The previous record for a dinosaur fossil was $31,800,000 paid in 2020 for a Tyrannosaurus rex fossil named Stan, which is going to be displayed in Abu Dhabi. A T-rex fossil named Sue, on display in the Field Museum of Natural History in Chicago, sold in 1997 for a mere $8.3 million.

What is the value of a dinosaur fossil that can command such enormous prices? Griffin says, “Apex offers a unique window into our planet’s distant past. The joy and awe every child feels coloring a Stegosaurus with their crayons will now be brought to life for the millions of people who have the opportunity to see this epic dinosaur in person.”

Are there religious or biblical connections to finding a dinosaur fossil? For some religious denominations, the answer may be negative. It is difficult to imagine how humans could exist with an animal of this size. As people look at this colossal dinosaur fossil they may be unable to accept the idea that humans and dinosaurs were contemporaries, and they would be right.

The Genesis account contains no Hebrew word that could be translated as “dinosaur” or “Stegosaurus. “Some people refer to “Behemoth” in Job chapter 40. The word “behemah” is used 51 times in the Bible, including Genesis 1:24-25 and refers to cattle. Stegosaurus was not a cow! “Remes” is also used in these verses referring to creeping creatures (also in Genesis 9:3) and is used 16 times in the biblical record. The “creation week” clearly refers to animals that the people of Moses’ time were familiar with, and that would not have included dinosaurs. The term “leviathan” (Job 41:1 and Psalms 104:26) refers to a great water creature, but Stegosaurus was not a water creature.

Dinosaurs were creatures God used to prepare the Earth for humans. Imagine the volume of plant material that Stegosaurus would have eaten every day. You can understand how they were instrumental in pruning the plants and spreading their seeds to provide the coal and mineral deposits humans would need. Like everything God does, the scale of what He did after Genesis 1:2 and before the Genesis creation week was massive. So, what is the value of a dinosaur fossil? We can join in the awe of seeing God’s plan as we look at dinosaur fossils like Apex, Stan, and Sue without feeling any doubt in our minds about the message of Genesis.

Cardinals Are Redder in Winter

I thought it was my imagination that when the Christmas season rolled around, the cardinal that came to my feeder was more brilliant red than I had ever seen before. Then I received an article from the Cornell Lab of Ornithology that made me realize what I observed was true – cardinals are redder in winter.

After the breeding season and when food is abundant, northern cardinals molt their feathers and grow new ones. During autumn molting, the cardinals look ugly, with areas of dark exposed skin and even some baldness. The ugly areas become covered with feathers tipped in gray. The gray feather tips wear off, exposing the brilliant red underfeathers. The birds reach the peak of brilliance by midwinter ahead of the spring breeding season.

The color change isn’t just for us to enjoy. It also attracts female cardinals. Studies at Cornell have shown that brighter red cardinals mate earlier and nest in better habitats, producing more offspring. The redness comes from carotenoids, pigments that occur naturally in foods such as red and purple fruits. Honeysuckle has red berries, as does dogwood and winterberry. All cardinals eat the same foods, but only the males reveal the pigments in brilliant reds.

Male cardinals are redder in winter because the genetics of the males and females are different enough to cause a color difference between the two sexes. Building a genome that produces this beautiful color is not easy. There are alternative ways males could attract females, as seen in other bird species.

Cardinals remind us that color and beauty are characteristics God has given us to enjoy. It was not an accident of some mutation that painted male cardinals red. We see amazing color in cardinals as well as peacocks, pheasants, painted buntings, parrots, splendid fairywrens, and lilac-breasted rollers, to mention just a few.

It is not your imagination that cardinals are redder in winter. Enjoy the beauty God has given us in His unique life forms in the sky.

Flamingo Complexity

The complexity of living things gives evidence of design rather than accidental chance. Flamingos that live in southern Florida, the Galapagos Islands, and throughout the Caribbean provide an example of that complexity. You have probably seen photographs of these five-foot-tall pink birds wading in shallow waters and using their long necks to find food. The pink color comes from pigments in their foods, such as brine shrimp and algae. The color is absorbed by body fat and deposited in the flamingo’s feathers. Flamingo complexity involves more than color.

Flamingos move their heads through the water because their tongues pump water into their bills, where comblike structures strain out their food. This activity helps purify the water and provides nutrition for the flamingos. Their legs are an engineering marvel. What looks like a backward knee is actually an ankle joint that can be locked. You would think that a bird with no talons and no sharp beak would be easy prey for various animals that live in coastal areas. The reality is that flamingos can rest and even sleep with their ankle locked while standing on one leg in the water far from shore, out of the reach of predators.

Flamingo complexity also involves their efficient reproductive system, with monogamous pairs producing one egg a year. They build a mound away from the shore and take turns incubating the egg by sitting on the nest mound. During incubation, the flamingo will frequently stand, stretch its wings, preen itself, and carefully lift and turn the egg with its bill. The incubation period is between 27 and 31 days.

The more we learn about the unique design of various birds, the more we have to doubt that this is the product of blind opportunistic chance. In Job 39:13-30, God challenges Job to explain the unique characteristics of birds, including the ostrich, stork, hawk, and eagle. If flamingos lived in Job’s area, they surely would be included as an example of God’s wisdom and design.

Sentient Beings and Purpose

A columnist featured in papers across the country is an animal doctor named Dr. Michael Fox. Dr. Fox believes that humans are not the only sentient beings, echoing the writings of those who deny that humans have any special properties or any right to use animals. This opposes the biblical view of humans and what God intended humans to do and eat. In Genesis 9:3, we read, “Everything that lives and moves about will be food for you. Just as I gave you the green plants, I now give you everything.”

The dictionary tells us that “sentient” comes from the Latin word meaning “feeling,” and it describes things that are alive, able to feel and perceive and show awareness or responsiveness. Having senses makes something sentient, or able to smell, communicate, touch, see, or hear. Dr. Fox and others cling to the idea that everything fits that definition, even applying it to nonliving objects: “atoms and stars … with their consciousness evolving with increasing complexity and individuation.”

Where do claims like Dr. Fox’s lead? First, it denies humans’ needs to enable them to survive. What do you eat if everything is equivalent and equal to human beings? Even if this concept is applied only to animals, you have an impossible situation. The world population of humans requires the consumption of proteins and minerals that we can’t obtain from a diet of only plants.

The most crucial aspect of understanding humans as unique sentient beings is that it gives purpose to life. Sentient beings can perceive, show awareness, and respond. Animals like dogs have senses designed for survival, including seeing, smelling, touching, hearing, and communicating. They do not have an awareness of self or a way of understanding that their existence has a purpose. They have no concept of a life beyond their present existence.

All humans need to take care of the world in which we live. That means caring for animals and plants in such a way that they thrive. Christians have a special reason for doing this because our Creator has challenged us to “take care of the garden (the planet)” (Genesis 2:15). We find this concept throughout the teachings of Jesus. Over and over, Jesus called us to love one another. The Greek word used for love is “agape,” meaning “to consider of enormous value.” We CAN love our enemy (Matthew 5:43-45) if we understand that our enemy is a unique being created in the image of God. Our enemies, like ourselves, are sentient beings with a purpose for existing.

Eye Design is Marvelously Complex

Eye design is marvelously complex. Human vision, with its rods and cones, is just one method of seeing, but other life forms have methods allowing them to see wavelengths we can’t see. Insects have compound eye structures consisting of individual units called ommatidia. Under the lens of each ommatidium, a transparent structure called a rhabdom stores photosensitive pigments known as opsins. Various types of opsins can detect different colors. The more kinds of opsins an insect has in its rhabdom, the more colors it can see.

Each insect has a different set of opsins depending on what it needs. Bees, for example, have a large combination of opsins, allowing them to see many colors of flowers. Some butterflies have opsins that enable them to see a particular plant. For example, monarchs can see milkweed plants, which their caterpillars need for nourishment. Dragonflies have a set of opsins that enable them to see ultraviolet light that human eyes can’t see. Dragonflies eat other insects, including some that are underwater, and ultraviolet vision allows them to see their prey.

The fossil record shows that insects used this method of color vision before the color vision method used by humans. Eye design is marvelously complex and highly designed to allow life to function in a world that needs balance and control. The more we see of the creation of living things, the more evidence we see for intelligence and design in the world around us.

God Has Used Animals to Teach Humans

Rattlesnakes are among the world’s most misunderstood animals. Bible skeptics refer to Genesis 3:1, saying that they don’t want to believe in a God who would create something as evil and useless as snakes. The passage reads, “Now the serpent was more crafty than any of the wild animals the Lord God had made.” Although He does not create talking snakes, God has used animals to teach humans.

The Bible has many stories of animals conveying a message to humans. Numbers 22:28-33 records a talking donkey redirecting Balaam. In 2 Kings 2:23-24, a group of teenage thugs who mocked the prophet Elisha were attacked by bears. In Jonah 1:17, we read that “the Lord prepared a great fish to swallow Jonah” to set him in a different direction. No matter what you make of those stories, animals that do terrible things to humans are not functioning normally. They are designed for a purpose, not to do horrible things to humans.

So, what possible value is there to rattlesnakes? They are designed to maintain environmental balance by controlling rodents of all kinds. A rattlesnake has a scent-detecting vomeronasal organ in the roof of its mouth, allowing it to smell a mouse or a shrew. In addition, a heat-detecting organ in the pits between its eyes and nostrils enables it to “see” a rodent in total darkness underground. This equipment is designed to eliminate small rodents, not humans.

The total number of people in the United States who die from venomous snake and lizard bites is five, according to the Centers for Disease Control and Prevention. Dog attacks kill many times more people than snake bites. Rattlesnakes have a warning built into their design that they use when threatened. I have personally been in situations where I have seen a rattlesnake within easy striking range of a human being that simply stayed in a striking position and never moved. Snakes do not want interactions with humans and are most abundant in environments humans do not frequent.

One interesting modern value to rattlesnakes is that medical researchers have found hundreds of proteins and enzymes in their venom that block or neutralize pain pathways, offering an alternative to highly addictive opiates. The venom also can dissolve blood clots and lower blood pressure. Snakes are victimized and denigrated, but they are not evil, and they are designed for a purpose. God has used animals to teach humans.

The Animal Understanding of Death

What do animals understand about death? That question has become such an area of interest that it has a name—comparative thanatology. Dr. Susana Monso has written a number of books and articles on the animal understanding of death, with special attention to opossums and chimpanzees. In her books, Monso provides information about the physiological changes in the opossum when it “plays dead.”

In a Time magazine article, Dr. Monso gave accounts of animals dealing with death. She told of a newborn albino chimp that other chimps were afraid of. When the dominant male killed the baby chimp, the behavior of the chimpanzee troop changed dramatically to a display of curiosity. Other cases cited are an orca who carried her dead baby over 1000 miles for 17 days and a gorilla who was weaned but attempted to suckle from its dead mother’s breast.

Dr. Monso argues that the animal understanding of death differs from human understanding. She says our human bias affects our view of comparative thanatology, but she believes animals understand death in their own way. Are the chimp, orca, and gorilla displaying grief, or are we interpreting them in light of what humans would feel and do? Do carnivores have empathy for the herbivores they eat? Those questions reflect what Dr. Monso calls an intellectual anthropocentrism bias.

That bias is reflected in some humans who refuse to eat meat because they feel empathy for the animal that died. To suggest that you won’t eat anything requiring death means you won’t eat anything. If you eat a plant or the seed of the plant, something has to die. Death is part of the design of life, and life would be impossible if nothing died. Either everything would die of starvation, and Earth would become devoid of life, or animal populations would overfill the planet.

The biblical understanding is that the Creator of life gave humans a special place in the creation. In Genesis 9:1-3, God tells Noah that all animal life would have the fear of humans and that humans would be responsible for managing all of life. Verse 3 also equates animal life with plant life. “Every moving thing that lives shall be food for you just like the green plant – I have given you all things.”

God gave only humans the ability to comprehend life after death. Animals’ understanding of the death of one of their kind is rooted in survival. We see this in the biblical discussion of this subject and the evidence available to all of us.
