Cardinals Are Redder in Winter

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.

The Value of Women

The Value of Women

If you listen to media hype or read books written by skeptics, you might conclude that the Bible is a product of a bunch of men who wanted to keep women under their thumb. This desperate attempt to denigrate the Bible shows incredible ignorance of the value of women in the Old Testament and the teaching of Jesus Christ in the New Testament.

The Old Testament portrays women as equal to men in every way. The creation account in Genesis 1:26-27 uses the plural term – “In the image of God created He THEM” – both men and women. The term “help meet” in Genesis 2:18 means one who would fill what is lacking in man. Modern translations use the term “helper.” The Bible describes men and women as having unique qualities of equal value. That is common sense, for how could a man produce offspring without a woman, and how could a woman become pregnant without a man?

The Old Testament does not portray women as merely glorified incubators. It called for men and women guilty of evil to be treated equally. (See Deuteronomy 17:2-7 and Numbers 5:5-7.) Proverbs 31:10-31 praises a woman who cared for her family and ran her own business. The laws of the Old Testament demanded that men were legally bound to care for their wives. Prostitution was forbidden, and kidnapping and rape were punishable by death. Women who were prisoners of war could be married or set free but never abused or sold. (See Deuteronomy 21:10-14, 22:25-29, 23:17.)

Jesus Christ treated women with respect and care, and the New Testament Church taught that women are equal in every way. Galatians 3:28 says, “There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus.” It is true that politicians and selfish males have attempted to use the Bible to control others, but the Bible promotes equality and the value of women.

Flamingo Complexity

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

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

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

God Has Used Animals to Teach Humans - Even Rattlesnakes
Western Diamondback Rattlesnake

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

The Animal Understanding of Death
This opossum is apparently really dead.

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.

Grounded Running in Birds

Grounded Running in Birds - Killdeer
Killdeer
Killdeer Nest
Killdeer Nest

Have you ever chased after a bird? Trying to catch a gull or a robin is an exercise in futility because birds can run at very high speeds. In our part of the world, we have a bird called the Killdeer, which lays its eggs on the ground in the open. As a teenager, I would chase the adult birds, thinking I could catch one, but I did not realize they were running on the ground to lead me away from their nest. I never thought about why I could never catch one because I would run out of breath before the bird would. Researchers have studied what they call “grounded running” in birds.

When humans are in a hurry, they use what is called “aerial running,” in which we pick up our feet. In grounded running, birds always keep one foot on the ground. Keeping a foot on the ground consumes less energy than human aerial running. Dr. Armita R. Manafzadeh of Yale University says that even though grounded running may look funny, “It’s actually a pretty smart thing to do when you have the anatomy of a bird.” According to Dr. Manafzadeh, “If we try to interpret the diversity of animal locomotion through a human-centric lens, we’re going to miss out on lots of really cool and equally viable ways of moving around the world.”

It is only through modern technology that we have been able to study the ground running of birds. What appears to be a silly-looking strategy is a beautifully designed system that meets the bird’s needs. The more we learn about the design and wisdom displayed in the creation, the more we see the wisdom and creativity of God.

“But ask the beasts, and they will teach you;
And the birds of the air, and they will tell you;
Or speak to the earth, and it will teach you;
And the fish of the sea will explain to you.
Who among all these does not know
That the hand of the Lord has done this,
In whose hand is the life of every living thing,
And the breath of all mankind?”
(Job 12:7-10 NKJV)

A System Benefiting Birds, Ants, and Trees

A System Benefiting Birds Ants and Trees
Yellow-olive Flycatcher in Costa Rica

Birds have an interesting method for keeping ants out of their nests and away from their eggs and chicks. Many ant species will eat everything in their path, and often, ants infect trees where birds build their nests. From a design standpoint, how can you build a system benefiting birds, ants, and trees?

Scientists have discovered that in tropical and subtropical areas, birds use fungal organs known as rhizomorphs to build their nests. Rhizomorphs are cord-like filaments that fungi use to capture nutrients, and they grow web-like in the canopy of tropical forests. These filaments repel ants to keep them out of the birds’ nests. Researchers have found that over 176 bird species use fungal rhizomorphs in their nests. Two bird species in Costa Rica build their nests almost entirely using rhizomorphs of horse hair fungus (Marasmius).

Researchers in Costa Rica found a symbiotic relationship between thorn acacia trees and ants. The ants collect nectar from the acacia, repel any invaders, and even trim back encroaching plants. The thorns of the acacia protect the ants from predation, and the rhizomorphs protect the birds. This complex system benefiting birds, ants, and trees is very difficult to explain by any chance process. The concept of God building a system that protects all three participants is simply an argument for His existence.

Macro-World Micro-World

Macro-World Micro-World
Brachycephalus pulex frog

We live in a macro-world in which we see and touch large things. Most of us don’t recognize there is a micro-world made up of very small things. Without the small things, the large things could not exist. The most obvious example of the need for small things is the food that animals need to survive.

Food chains start with the very small. Carnivorous insects that don’t eat plants provide the starting point for food chains. As technological tools become available, scientists discover more and more small animals, even some that are vertebrates. One example is the discovery of tiny Brachycephalus pulex frogs, also known as Brazilian flea toads, because they can jump 30 times their body length. They are only 7 millimeters (.3 inches) long, and unlike other frogs, they don’t go through a tadpole stage. Their eggs hatch directly into tiny frogs.

Scientists have found tiny animals in desert environments providing a basis for life in what would appear to be a sterile environment. Tardigrades, known colloquially as water bears or moss piglets, are another example of very small creatures that are important agents for life in the macro-world.

Many plants and animals that allow life to exist are not perceived through our senses. Everywhere we examine the macro- or micro-world, we find a design created by God. Romans 1:20 tells us, “..the things of God which the eye is unable to see ever since the world was made are clearly perceived through the things that are made.” The things we can’t see include the spiritual things of God and the small things in the material world as well.
