Beauty of Earth’s Diversity

Beauty of Earths DiversityThe plant in the picture is called the “bird of paradise.” It is neither a bird, nor is it found in paradise. However, it is indeed a beautiful example of the beauty of Earth’s diversity in the plant world. One of the primary reasons many of us enjoy travel and visiting museums, zoos, and arboretums is that we are enthralled with the incredible diversity of living things.

We want to suggest that this diversity is more than a device to entertain us humans. From a scientific standpoint, it is the diversity of life on Earth that has led to the high standard of living available to us on this planet. As geneticists unravel the genome of living things, it becomes more and more apparent why agricultural breeding practices of the past have been successful. The production of super chickens, super cows, low-fat pork, and all the other unique breeds has been possible because of all the different genetic options God built into life. If, for example, there had been only one set of genes for all bovines on this planet, such cattle as the Charolais would not have been possible. It is only because we have an infinite number of genetic possibilities to draw from that we can select those that will serve our particular needs.

In plants, this is equally obvious. We have only begun to appreciate all that plants can do. Scientists have studied only a small percentage of all plants on this planet to see how we can use them. Cures for cancer, AIDS, the common cold, and a variety of other ailments may well be in a plant we have not yet investigated. It is self-evident in today’s world that solving the problem of hunger lies in the fuller use of plants. The diversity of plants holds the key to better nutrition, more and better fabrics to protect and shelter us, and even the improvement of air quality.

In God’s creative wisdom, He gave us a wide diversity of life of all kinds and told us to “take care of the Garden, dress it, and keep it” (Genesis 2:15). The future has vast potential for good if we will use in a constructive way all that God has given us. To arbitrarily destroy any of this diversity and thus end its potential usefulness is not only poor management of the “Garden,” but also the worst kind of foolishness.

We also suggest that the beauty of Earth’s diversity of humans offers the potential for vast good. Each of us has a gift designed into our makeup that uniquely qualifies us to bring great blessings to others. Paul said it best:

“According to the grace given to us, we have different gifts: If prophecy, use it according to the proportion of one’s faith; if service, use it in service, if teaching, in teaching; if exhorting, in exhortation; giving, with generosity; leading, with diligence; showing mercy, with cheerfulness” (Romans 12:6-8). See also 1 Corinthians 12:8-27.

Cotyledon’s Engineered Preparation for life

Cotyledon’s Engineered Preparation for lifePlant seedlings emerging from the ground use the cotyledon’s engineered preparation for life. You may not be familiar with cotyledons, but you have undoubtedly seen them on newly emerged seedlings.

To get the idea, think about some other engineered devices that serve an essential preparatory function. When skydivers jump from a plane, they use carefully engineered equipment. The first thing they deploy to prepare for landing is a pilot chute. The pilot chute can’t land them safely on the ground. Its purpose is to deploy the main parachute. Perhaps more familiar to most people is the limited-use spare tire for automobiles. Those “donuts,” as many people call them, are not designed for high-speed driving or for driving long distances. They are engineered to get you to the nearest service station where the punctured tire can be repaired or replaced. The pilot chute and the limited-use spare tire are examples of engineered preparation.

Just as the pilot chute is packed into the jumper’s gear and the donut is packed into the vehicle, there is something packed into the seed called a cotyledon. Scientists classify flowering plants (angiosperms) as monocots or dicots depending whether they have one or two cotyledons folded into the seed. As soon as the seed has sent a taproot into the soil, it pulls in moisture and uses the hydrostatic pressure to push up a green shoot bearing the cotyledons. As those “donuts” break through the surface, they inflate to provide temporary, emergency photosynthesis. The seedling begins to drink up the water and nutrients from the taproot and use energy from sunlight to kickstart the photosynthesis process.

As the cotyledon’s engineered preparation for life gets the new plant started, real leaves begin to form. In a sense, the cotyledons have taken the plant to the first service station or deployed the main chute. Now it is ready to go from a seedling to a full-grown plant or tree. The seedling still has many challenges ahead, just as the parachutist or motorist does. But just as having the pilot chute or the donut packed and ready for deployment aids the jumper or the driver, the cotyledon supports the plant. Would anyone suggest the pilot chute or donut are merely accidents? We know those devices would not be possible without engineering design. In truth, cotyledons require far more complex engineering that only the master Designer can do.

Spring-loaded Movement in Living Things

Spring-loaded Movement in Living ThingsAn interesting study of living things in the world around us involves how things move from one place to another. There are many creatures with muscles that move their legs or wings to travel from place-to-place. Other forms of life use spring-loaded movement with power greater than muscles can provide.

The larvae of the gall midge Asphondylia flip with power by using a built-in latch that acts as a spring. Gall midges lay their eggs on silverrod or goldenrod plants (Solidago). The midges grow from an egg to a larva inside a gall that grows on the plant. The larva’s body forms into an ellipse by meshing together the back and front using a velcro-like surface on each end. As the midge larva grows, the tension on the surfaces increases until it finally breaks free, shooting the midge as far as 36 times its body length. We previously reported on the so-called “Dracula ant” (Mystrium camillae) which has the world’s fastest jaws that operate on a mechanism which gives them spring-loaded movement.

Some plants like the Chinese Witch Hazel (Hamamelis mollis) have a similar structure in their fruit. As the fruit grows, it builds up stress until the edges of the fruit break, shooting the seed great distances. That spring-loaded launch method spreads the seeds over a wider area. Also, we previously reported on the sandbox tree (Hura crepitans) nicknamed “the dynamite tree.” Its seedpods open explosively by a spring-loaded movement that scatters the seeds.

These are all design features built into the very structure of the organisms to allow locomotion. Even the smallest creatures such as ants and midge flies and plants that are rooted in place use spring-loaded movement. Everywhere we look in the creation, we see God’s designs at work. His wonder-working hand has created a great diversity in all of life.

As Paul wrote in Romans 1:20, “For the invisible things of Him (His wisdom, power, and design) from the creation of the world are clearly seen, being understood by the things that are made even His eternal power and deity; so that mankind is without excuse…”

Algae Solutions to Human Problems

Algae Solutions to Human ProblemsWhen you hear the word algae, negative thoughts may come to your mind. You may have problems with algae growths in your pond or birdbath. You have heard about toxic algal blooms that have hit seafood industries on the Pacific Coast. Many of us have viewed the red tide in Florida first hand. There are lawsuits in progress against companies that allowed chemical runoffs to trigger the destructive growth of algae in lakes and the ocean causing economic hardship for fishing trades and seafood producers. Unlike human-caused algae problems, there is a promise of algae solutions to human problems.

Consider the following facts:

Algae is probably our best tool for reducing greenhouse gases. Algae take carbon dioxide from the air and produce oxygen. More than half of the oxygen in Earth’s atmosphere comes from converting carbon dioxide to oxygen and algae is the primary agent for doing that. There is good evidence that excessive algae growth in the past caused global cooling.

Phytoplankton algae grow world-wide and make up the base of aquatic food-chains, eventually leading to most of the seafood we eat.

Giant kelp, which are algae, provide food and protected ecosystems for ocean creatures.

Cyanobacteria, also known as blue-green algae, such as spirulina contain proteins, vitamins, minerals, and essential fatty acids. People in many countries have been harvesting spirulina for nutrition since the 1940s. Japanese cooks use algae in soups and sushi wrappers. The additives agar and carrageenan from algae are used in ice cream and jellies.

Symbiotic relationships exist between algae and coral, helping to prevent storm damage to coral reefs that house sea life and protect shoreline structures. Algae solutions to human problems are many.

Research continues into how we can use algae to produce fuel. New foods made of algae are being developed. Most recently sea grapes, which are algae, have been used as green caviar because their texture and appearance looks like caviar and they are very nutritious.

God has provided for us in so many ways that it has taken our entire human history to discover them. For many years people did not eat tomatoes because they were considered to be poisonous. That seems silly to us today when whole industries are built around the tomato. In the future, perhaps we can say the same of algae. These rootless, leafless plants have incredible potential to provide algae solutions to human problems both here on Earth and as we travel into outer space.

A Flower or a Weed?

Daisy - A Flower or a Weed?
This wildflower can be found growing in fields and meadows. Its soft petals and yellow core make it universally recognizable. Many related plants are called daisies, but the common daisy (Bellis perennis) is native to Europe and is sometimes called the English daisy due to its native location. However, daisies have become so prevalent around the world that some say they make up almost 10% of all flowering plants on Earth. This leads to the question of whether it’s a flower or a weed.

The name “daisy” comes from “day’s eye” because the head closes at night and opens with the sunrise. You may look at the common daisy and believe that the head is a solo flower. In reality, it’s a composite flower made up of a cluster of flowers called an inflorescence. Each inflorescence grows on a single, leafless stem with rounded leaves growing from the base. Common daisies resemble another wildflower known as chamomile. However, chamomile has multiple flower heads growing on the same stalk.

Common daisies are robust and can thrive in many different types of soil, in full sun or partial shade, as long as minimum temperatures remain above -30 degrees F (-34 C). They grow on every continent except Antarctica. Daisies can grow in practically any valley, meadow, or field. If the conditions are right, daisies will populate themselves in enormous numbers engulfing the ground like weeds. A meadow full of daisies is a beautiful natural scene. However, in some areas, they are considered to be invasive weeds. In fact, they are so hardy they may crowd out noxious weeds. So is it a flower or a weed?

Daisies are beautiful to look at, but they can also be beneficial in other ways. Daisies can help improve the biodiversity of the household garden by attracting pollinating insects as well as birds that feed on the insects. Young daisy leaves can be added to salads, and they supply vitamin C. The buds and petals are also edible in soups or salads. Some people have also used them for treating gastrointestinal disorders. Children use them to make daisy chains, and young women count the petals to the refrain “he loves me; he loves me not.”

So the question of whether it’s a flower or a weed depends on your perspective. We prefer to think of them as flowers. Whether wild or cultivated, we find the number and variety of flowers in the world amazing. Apparently, God loves beauty, and He has given humans the ability to enjoy it also. After all, the Creator made us in His image.

Saguaro Desert Old-Timers

Saguaro Desert Old-TimersThe saguaro (pronounced suh-wah-roh) cactus is found only in the Sonoran Desert areas of southern Arizona, northern Mexico, and a small area of southeast California. We call them saguaro desert old-timers for a good reason. Saguaros grow very slowly as a single stem for perhaps 75 years before developing arms. Plants with five arms may be 200 years old.

Saguaro flowers bloom at night from April to June. They close by noon the next day, never to open again. Saguaro flowers can only be fertilized by cross-pollination so there must be a creature to carry pollen from one plant to another. Because the flowers bloom at night, bats are the pollinators. They drink the nectar and transfer pollen from plant to plant.

A successfully pollinated flower will produce a green, oval-shaped fruit with bright red pulp. Many desert creatures eat the fruit and aid the saguaros by spreading their seeds. Only a small percentage of the seeds will ever germinate, but that’s okay because each flower produces as many as 4000 seeds.

Not only do the saguaros have a symbiotic relationship with the bats which consume their nectar and the many creatures who consume its fruit, but it also provides shelter for many desert animals. Saguaros become apartment houses for birds, lizards, desert rodents, and reptiles, as well as a whole entourage of insects.

Saguaros are remarkably well-designed for life in a dry climate. The outside of the plant has pleats like an accordion. The pleats allow expansion for storing large quantities of water when the rains come. As with other cacti, the saguaro has needles rather than leaves to reduce the loss of moisture by transpiration.

Saguaro desert old-timers are designed in a marvelous way to live in the harsh conditions of the desert while providing food and shelter for various desert creatures. They are another indication of a Master Designer of life.

God’s Horticulture System

God's Horticulture SystemOne of the most interesting designs in the natural world is the way plants are seeded. For plants to grow, there must be soil, moisture, and the planting of the seeds. Many places have moisture and soil that could support plant life, but how do you get the seeds to that area? The solution is God’s horticulture system.

In our area of the world, we have seen human influence cause an area to be bare of significant trees or vines. The building of highways or the destruction of fires and floods can leave an area completely void of any kind of plant growth. Around the interstate highway system in our area, we see the growth of red cedars. These desirable trees are slow growing and can become valuable timber. The state doesn’t plant trees, and yet many red cedars are growing along our highways.

The animals planting these evergreens are birds. The cedars provide valuable habitats for the birds, and the birds plant the trees. Cedars produce blue berries that the birds eat. If you put one in your mouth, you would cringe at their bitter taste and obnoxious consistency. Birds eat them with zest and in large quantities. Birds get nutrition from the berries, and their digestive systems are specifically designed to process the seeds for growth. The birds drop the seeds along with natural fertilizer in barren places. Birds and trees benefit from this symbiosis in God’s horticulture system.

Other important seeders are squirrels. They are designed to bury seeds such as acorns, but their brain limitation causes them to forget a percentage of the seeds they bury. The design of fruits and nuts provide nutrition for animal life while the animals provide a means for the plants to grow in places far from their ancestors.

When scientists look at the diet of dinosaurs by examining their petrified excrement, they find that dinos were the seeders of their day. The plant-eating dinosaurs spread the seeds of the plants they ate along with nutrients that allowed fantastic jungles to form. The meat-eating dinosaurs kept the population of plant eaters under control so they wouldn’t eat all of the plants.

When we look at all the different kinds of seeds, the nutrients they contain, and where they can grow, we see a plan and design. Humans are still learning how to copy God’s horticulture system to feed our growing population.

Ice Algae – Designed Polar Grass

Ice Algae
Have you ever wondered how animals that live near Earth’s North and South Poles survive? What do they eat, and how can any kind of food chain exist? The answer to this is ice algae.

Unlike most plants, algae do not have flowers, roots, stems, leaves, or vascular tissue. However, ice algae, like most plants, provide the starting point for a food chain. In this case, it is a food chain in very cold places. Tiny krill, penguins, seals, polar bears, and blue whales all depend on ice algae to survive. In 2016 Dr. Thomas Brown of the Scottish Association for Marine Science studied polar bears and found that 86% of the polar bears’ nutrition came from a food chain that originated with ice algae.

Ice algae have chlorophyll so they can use whatever light is available for photosynthesis. There are a variety of types of algae that live in different conditions. Some live on the surface of the ocean, some on the floor of the ocean, and some in or on the ice itself. Ice algae produce fatty acids which supply nutritional value for animals that live in what would otherwise be a nutritional void. Because there is ice algae, animal life is abundant under, in, and around the ice at both poles.

God has provided interesting food chains all over the planet. As we study global warming and its effect on life in places like the polar seas, we see more of His handiwork and learn why we need to take care of it. The admonition of Genesis 2:15 to “take care of the garden to dress it and keep it” applies as much to us today as it did to Adam and Eve.

Chocolate Flies at Work

Chocolate Flies at Work - Cacao Tree Flowers and Pod
Thank God for chocolate flies. No, we are not talking about chocolate-covered houseflies. That sounds repulsive to us too. We are talking about the tiny flies that are essential to the production of the chocolate we love.

Chocolate comes from the seeds of the cacao tree (Theobroma cacao) which is native to the rainforests of South America. When early tribes in the Amazon and Orinoco River area discovered uses for the cacao tree, they started what became a chocolate craze that is still going on today. From there, interest in the trees and the tasty substance they produce spread to more of northern South America, into Central America, and into Mexico. The Aztecs even used cacao beans as money.

However, growing the cacao beans is not easy. The tiny white flowers that produce the beans require a small insect pollinator. The flowers grow out of the trunk of the tree where pollination by a bird or mammal would not be practical. Even bees or butterflies are too large. That’s where the chocolate flies come in. The pollinators that can do the job are tiny flies, or midges, in the family Ceratopogonidae. They are small enough to get into the flowers, and they are on the right work schedule. The cacao flowers open just before dawn—a time when the midges are most active. It seems like a planned arrangement. They are not really chocolate flies, but they are essential helpers for chocolate farmers.

As farmers began to grow cacao on plantations, the pollination process was not working well. Human pollination of the flowers by hand is a difficult job and not as effective as the work of the little flies. The midges were not doing the job because they prefer the shade of the rainforest over the open spaces of cacao plantations. Coincidentally cacao trees grow well in shady areas.

Farmers found a solution by planting small areas of cacao in the ecosystem of rainforest areas. Of course, that limits the areas where it can be grown and thus the amount of chocolate produced. However, the people of the world will not give up their desire for chocolate, and a fly the size of a pin-head makes it possible. This is just one more example of the importance of rainforests and the excellent design God has given this amazing planet.

Beneficial Fungus Called Smut

Beneficial Fungus Called Smut
Those of us who have grown sweet corn have almost always had to fight smut. That black and gray growth on corn looks disgusting. It is actually a fungus known scientifically as Ustilago maydis, and it has been around for a long time. Even though we dislike it, in some ways smut is a beneficial fungus.

Archaeologists studying ancient Puebloan people have found significant amounts of corn smut spores in their feces. That indicates that maize (corn) made up as much as 80% of the diet of ancestral Puebloan people and it included a great deal of the fungus.

One of the mysteries of ancient peoples in America is why they didn’t have nutritional diseases that were common in the world at that time. The most serious of those was the skin disease pellagra which is caused by a lack of niacin (vitamin B3) in the diet. The amino acid that prevents pellagra is missing from the maize but is present in high concentrations in the smut.

We generally have a negative attitude toward fungi, but there are many examples of beneficial fungus. Remember that penicillin was derived from a fungus. Now we find corn smut also offers a benefit. God has a use for everything He created, but sometimes it takes us a while to figure out what that use is.

We have a children’s book about beneficial fungi, and you can see it online HERE.
