Lemming Suicide Myth

Lemming Suicide Myth
Lemmings are small rodents with long, soft, colorful fur and short tails that live in the Arctic tundra. They reproduce rapidly, and their population varies dramatically, usually over a four-year cycle. Scientists have studied the variation in lemming populations for many years, but they don’t entirely understand it. However, the lemming suicide myth is not an explanation.

Contrary to popular stories, lemmings do not commit mass suicide by jumping off cliffs into the sea to drown. False lemming legends are not new. In the sixteenth century, because of their rapid population increases, a story was started that they fall out of the sky when it rains. That idea was proven to be false.

The story of the mass suicide has been depicted in songs, movies, video games, stories, and a 1985 Apple TV commercial until most people accept it as true. The worst case of deception was in the 1958 Disney movie “White Wilderness.” The film won an Academy Award for best documentary, but it spread false information with a staged lemming suicide jump. It was later revealed that the lemmings were forced off the cliff by the camera crew.

When their population density becomes too high, lemmings migrate to find food. Since they can swim, they sometimes migrate across bodies of water. Occasionally some may drown in the crossing, but it’s not mass suicide. In 1980, Gary Larson’s “The Far Side” comic showed a group of lemmings jumping into the water. The last lemming in line was wearing a life preserver. Following the principle of natural selection, that lemming would have been the one to survive and reproduce. We would presume that its offspring would inherit the caution and be smart enough not to follow the crowd. Then we would assume that lemmings would evolve into creatures who would no longer take the plunge. It’s a matter of survival of the fittest, or perhaps the smartest.

The lemming suicide myth is persistent, but false, like the myth that we use only ten percent of our brains. The bottom line is, God didn’t create lemmings to be suicidal. He also didn’t create humans to be gullible.

The Not So Common, Common Pigeon

Common Pigeon
You may think that pigeons are more of a nuisance than anything else. Many of us have had to scrub pigeon droppings off of statues or home decorations. The sheer number of pigeons that we see in our cities can make us take these birds for granted. Discover magazine for August 2018 published a dossier of the unique features of the common pigeon, also known as the rock pigeon or rock dove. These features show it is incredibly well-designed to survive in almost any environment on Earth. Here are some interesting characteristics:

Pigeons are one of only three kinds of birds that have an enlarged crop which is an extension of the esophagus. They use this crop to store food which they eventually give to their young.

Most birds drink by taking in water and then putting their heads back to allow the water to run into their stomach. Pigeons have a unique beak that acts like a straw enabling them to suck up the water.

Wing muscle makes up about 60% of a pigeon’s body weight making pigeons excellent flyers. They can cover 500 miles a day and can reach speeds of 50 mph.

Pigeons can navigate in ways that are still poorly understood by scientists. Experiments have shown they can use sound, magnetic fields, landmarks, the Sun, and even smell. Like the Arctic Tern, the common pigeon seems to possess multiple navigational tools.

Pigeons have a concept of self and can recognize themselves in a reflection. There are only six other animals that can do that.

Pigeons are more capable than babies and toddlers in recognizing the letters of the alphabet.

Pigeons use “fright molt” which is the ability to shed feathers when attacked.

Humans have used pigeons for food, for carrying messages, and for psychological testing. In fact, the famous psychologist B.F. Skinner taught pigeons how to play ping pong. Our most abundant birds like pigeons and crows were designed to do remarkable things. God frequently advises us to learn from His creation–including all life forms. (For example, Proverbs 6:5, “Go to the ant, you sluggard; consider its ways and be wise.”) We can also learn from the common pigeon which is not so ordinary after all.

Intelligent Alien

Octopus - Intelligent Alien
Science fiction writers and UFO proponents like to propose strange looking aliens that can do incredible feats. The common octopus is a beautifully designed and incredibly intelligent animal that could compare to any intelligent alien of science fiction.

The octopus has no bones in its body, in fact, the only hard part of an octopus is its beak. That means that the octopus can take any shape and fit through almost any opening. One famous example is an octopus that escaped from an aquarium in New Zealand. That animal picked apart the lid on its aquarium, crawled out, went across the room and down through a drain hole that led to the sea and has never been seen again.

Octopus arms are muscular, boneless, and lined with suckers that are covered with chemoreceptors similar to our own taste buds. An octopus can taste everything it touches. They live in oceans around the world from equatorial waters to Antarctica and the Gulf of Alaska and from deep-water trenches to shallow reefs.

The arms are also filled with neurons, so the brain cells of an octopus are in its arms and not its dome. The octopus has sacs of pigments which are controlled by the muscles. It can release this “ink” as a defense mechanism. Its arms also have cells that reflect and scatter light. That means an octopus can control what it looks like. It can resemble a sea snake, a fish, anemones, jellyfish, sand, or seaweed. It’s a master of disguise. In addition to the right color and form some octopus species copy the movements of whatever animal they imitate. The camouflage does not seem to be accidental but is controlled by the octopus itself.

For a soft-bodied animal to survive in the ocean, some unique characteristics must be designed into its DNA. We think the number of features the octopus has is astounding. To have one unique characteristic might be possible–produced by a mutation and supported by natural selection. To have all of the abilities of an octopus would not happen by one mutation. Fossil evidence indicates that octopuses have been around throughout the history of the oceans. They even predate the dinosaurs.

Octopuses resemble an intelligent alien, and they certainly make E.T. look like nothing special. They give evidence of the Designer of life.

Color Vision Gender Differences

Color Vision Gender Differences
There are many differences between men and women, but you realize that there are color vision gender differences?

Light is electromagnetic radiation that stimulates our eyes. There are only specific frequencies of the electromagnetic frequency spectrum that we can see. Frequencies below the range of visible light are called infrared. We can sometimes feel infrared radiation as heat, but we can’t see it, although some animals can. Frequencies higher than visible light are ultraviolet which we can’t see, but it affects our skin and can cause sunburn. Some animals can see infrared light.

Within the visible spectrum of light that humans can see, different bands of frequencies affect our eyes differently. Most of us have receptors in our eyes for the wavelengths which we call red, green, and blue. When light stimulates those receptors, they send a signal to our brain which combines the signals to allow us to see many variations in colors.

People with colorblindness (mostly men) have one of those color receptor categories missing. The missing color may be either red or green. Why are men colorblind more often than women? The genes that encode the red and green receptors are located in the X-chromosome. Men have one X- and one Y-chromosome. Women have two X chromosomes. That means that if a man has a defective X-chromosome, he is out of luck. A woman would need to have two defective X-chromosomes to be colorblind.

It’s interesting that the chromosome pair that creates the sex differences also explains the color vision gender differences. God said, “It is not good for man to be alone” and He took something out of the man to create a woman. Then He put them together to complete each other. In many ways, men and women really do need each other to be complete.

Adding Nitrogen to the Soil

Adding Nitrogen to the Soil
We all know that lightning can be dangerous. Each year people are killed, and a great deal of property damage occurs because of lightning. We don’t usually consider the benefits of this powerful force. Nitrogen in the soil is essential for plants to grow and lightning is a natural method of adding nitrogen to the soil.

Although lightning can be dangerous, it also produces materials that are critical to life. All living things depend on the chemical element nitrogen. Your body contains molecules known as proteins. Proteins are made up of several elements, including nitrogen. Nitrogen is essential for proteins, but it is very hard to make nitrogen into proteins. Even though nitrogen makes up 78 percent of our atmosphere, we don’t get any nitrogen from the air we breathe. With each breath, we inhale and exhale nitrogen without using it. The nitrogen in the atmosphere has three electron bonds between the atoms, and that is a very strong and stable chemical arrangement. It takes an enormous amount of energy to break those bonds to free the nitrogen.

When lightning slices through the atmosphere, it knocks electrons from nitrogen atoms. The atoms are then free to combine with oxygen and hydrogen in the atmosphere forming nitrates. Rain carries this new compound to the ground enriching the soil with nitrates which are the building blocks of proteins. Plants synthesize the nitrates into proteins. When animals eat the plants, they get proteins. When we eat the plants or animals, we get the proteins we need to build more proteins.

Without lightning and the other processes for adding nitrogen to the soil, life could not exist on Earth. There is a purpose in the design of lightning. The Designer has also given us the intelligence to avoid many of the adverse effects of this powerful force.

Electrons Are Essential for Life

Electrons Are Essential in the Elements of Life
Everyone knows that electrons allow us to have computers and other electrical devices, but you may not realize how many ways electrons are essential. The mass, charge, magnetic properties, and spin of electrons are all designed to make life possible. It is amazing that something far too small for us to see is so important.

The changing momentum of electrons creates light which is essential for life. Electrons are also the fundamental cause of all that happens in chemistry. Atoms bond with other atoms to make molecules by exchanging or by sharing electrons. The complex organic molecules in your body, including DNA, are held together by electrons. The properties of every element in the universe are determined by how its electrons are arranged around the nucleus.

The oxygen atom with eight electrons joins with two single-electron hydrogen atoms to form water. The arrangement of the electrons in the oxygen atom causes the oxygen/hydrogen union to form in a way that gives water its unusual properties. The arrangement of electrons and the way the atoms bond causes water to dissolve salts, freeze from the top down, form crystals when freezing, and have surface tension. Without these unique properties of water, life would not be possible on Earth.

The arrangement of the six electrons in the carbon atom allows it to form enormous numbers of carbon compounds in various patterns. Because carbon can build so many organic compounds, our carbon-based life can exist. Without the particular arrangement of electrons in oxygen and carbon, life would not be possible.

Add to carbon and oxygen more than 90 other elements and their electron arrangements, and you can see that the probability of all of this happening by chance is not reasonable. We can be sure that a Master Designer created this complex system in which electrons are essential.

Beauty in Structural Color

Beauty in Structural Color on a Peacock
Some of the most beautiful colors you will see are found in birds and butterflies. We usually think of color as coming from pigments or dyes which reflect specific colors of light. However, the most intense and beautiful colors in the feathers of birds and the wings of butterflies don’t come from pigments. These animals display beauty in structural color.

Microscopic structures create structural color within the bird’s feathers or the butterfly’s wings which interfere with the frequencies of visible light. For example, the pigment in a peacock’s feathers is brown, but when you look at a peacock, you see blue, green, and turquoise in unusual patterns. Structural color can create color effects more intense than pigments, and structural color doesn’t fade like pigments. Structural color can even create an effect called iridescence in which colors change depending on the viewing angle. You can see this effect when you look at a CD or DVD.

What is the purpose of the colors in birds? The purpose may be for camouflage, to attract mates, or to indicate dominance. But in many cases, the colors seem to give no advantage. The beautiful colors merely exist for the beauty. When there is no evolutionary advantage for the colors, how did they get there? We humans appreciate beauty and enjoy looking at the beautiful colors. Could it be that colorful birds and butterflies were created by a Designer who is an artist who loves beauty, and who created us in His image. Could it be possible that God created the beauty in structural color for us to enjoy?

Ultraviolet Defense Mechanism

Ultraviolet Defense Mechanism
The human eye is an incredible creation. It not only allows us to sense the visual world around us, but its connection with the brain is amazing. The image that falls on the back of your eye is inverted, and your brain turns it over so that you see everything right side up. Most animals have eyes that do unique things, but not all of them use visible light. Ultraviolet light has a higher frequency than the light we can see. That means it is more energetic than the human eye can detect but less energetic than Xrays. Many animals use ultraviolet light as tools to enable them to survive. Some birds can see in the ultraviolet as do monitor lizards, some foxes, and some snakes. Sometimes ultraviolet vision helps them to find food. Other times prey use it as an ultraviolet defense mechanism.

Among the things those ultraviolet-seeing predators eat are lizards. A lizard called the blue-tongued skink lives on the ground throughout much of the continent of Australia. This lizard would seem to be an easy target for predatory birds and ground-dwelling animals. However, it has an ultraviolet defense. The tongue of the blue-tongued skink is highly efficient at reflecting ultraviolet light. When threatened by a predator, the lizard will open its mouth wide and stick out its tongue. The tongue will give off a blast of reflected ultraviolet light. Experiments show that birds and ground animals that see in the ultraviolet are startled by the sudden burst of ultraviolet radiation and veer away from the lizard.

One of the problematic things in designing any natural environment is building a system where living things can survive over the long term. If there is not a balance between predator and prey, the result is disastrous. Many years ago someone introduced rabbits to Australia. They had no natural enemies, and they reproduced so rapidly that soon the whole continent was overrun with them.

God has designed prey and predators in such a way that, if humans don’t mess it up, the environment and all of the living things in it can survive indefinitely. We are only now beginning to understand how difficult that is, even involving ultraviolet defense mechanisms. We need to allow the Earth to continue to be fruitful.

Coevolution – Stretching Truth to the Limit

Coevolution and Angraecum sesquipedale
One of the interesting characteristics of modern-day evolutionists is how far they will stretch credibility to support the model they assume to be true. Carl Zimmer in his book Evolution–The Triumph of an Idea gives a classic example of such a stretch when he calls our attention to an orchid found in Madagascar named Angraecum sesquipedale. It’s a story of coevolution.

You may recall from high school biology that flowers have both female organs called pistils and male organs called anthers. To cross-pollinate from one flower to another, the pollen from one plant must go to the “eggs” of another plant of the same species. The problem, in this case, is that the orchid has an 11 to 16 inch (28-40 cm) shaft at the bottom of which is a pool of nectar. It is far out of the reach of the usual pollinators of Madagascar. So how does pollination occur? It turns out that there is a microscopic moth that does the pollinating. What is unusual about this moth is that it has a tongue that is coiled up like a watch-spring taking up virtually no space. When the moth uncurls the tongue, it is 16 inches (40 cm) long. While the tongue is drinking in the nectar, the head and body of the moth are pollinating the orchid.

This is classic symbiosis. The orchid cannot reproduce without the moth, and the moth would starve to death without the orchid. The question is, “How could such a relationship came into existence?” Evolutionists would have us believe that the orchid evolved the shaft, the nectar pool, and the placement of the pollen at precisely the same time that the moth evolved the watch-spring tongue. At some point in the process, the two came together, and the symbiotic relationship was born.

The orchid and the moth are just one of a vast number of symbiotic relationships between species. Some of those mutual relationships are between predators and prey with physical characteristics that allow both to survive. Biologists say that it is just a matter of coevolution. However, as our understanding of genetics has improved, the difficulty in explaining these symbiotic relationships has gotten worse. Not only are the physical characteristics needed, but the genetic combinations must be very specific.

You will find more details on this interesting subject in F. LaGard Smith’s book Darwin’s Secret Sex Problem published by Westbow Press.

Jerboa by Design

Jerboa by Design
One of the things that scientists have studied in some detail is food chains. We now understand that for life to proliferate in harsh environments, it sometimes takes a highly specialized animal that is unique to that environment to fill the niche of food that other animals need. The deserts of northwest China, southern Mongolia, northern Africa, and the Arabian peninsula are good examples of harsh environments. The creature at the foundation of the food chain for higher forms of life is the jerboa by design.

This animal is about three inches (7.6 cm) long but has a tail that is over six inches (15 cm) and is flared at its end. The body is mouse-like, but the ears are a third longer than its head. The snout is like a pig’s, and its back legs look like a miniature model of a kangaroo. The back feet are elongated and very powerful and are covered with tufts of stiff hair. The front legs are very short, just barely able to reach its mouth.

The jerboa uses all of its unusual characteristics in a way that allows it to survive in an environment where most animals couldn’t last a day. The tufts on the feet enable it to walk on sand. The large ears are sensitive to very low volume sounds to hear predators approaching. The tail is a prop for standing still, and it gives stability when the animal jumps. It’s like a rudder in the air. When chased by a predator, the jerboa will change directions quickly and often to avoid capture. It can hop at up to 15 miles (24 km) per hour.

The jerboa ‘s diet is almost entirely insects, and it plays a major role in controlling the insect populations. The jerboa is a primary food source for birds of prey. The jerboa’s unique features enable it to survive even though it has many predators.

There are elaborate evolutionary explanations as to how this animal developed, but we see the jerboa by design. So many characteristics are unique to the jerboa that it requires a good imagination to derive a possible evolutionary scenario. God has designed creatures to fill even the harshest environments. Their capacity to adapt to those environments is further testimony to the wisdom built into the creation everywhere we look.
