Orphan Crops to Provide Food

According to the National Science Foundation (NSF), more than 34 million people in the United States do not have enough food to eat. The NSF is funding research into orphan crops to provide food.

The groundcherry is a member of the nightshade family of flowering plants that includes tomatoes, potatoes, eggplants, and bell peppers. Although its relatives are important crop plants, groundcherries are called “orphan crops” because they grow wild and have no agricultural value. Groundcherries are common all over America, are easy to grow, and can be modified genetically. They have a papery, balloon-like husk or inflated calyx surrounding the berries.

Using the CRISPR genome editing tool, researchers funded by the NSF are working to modify groundcherries and other orphan crops to provide food. Zachary Lippman and Jia He of the Cold Spring Harbor Laboratory feel that the groundcherry has a significant untapped potential to make it useful as a food for humans. They hope their research will lead to new food sources from various plants to build and advance a bioeconomy that will eliminate hunger on our planet.

Understanding the design of a plant that might have been considered unusable or even toxic in the past can lead to a new food source. In the distant past, people thought tomatoes to be toxic. We may find ways to use other orphan crops to provide food. Many familiar plants may have the potential to strengthen food supplies.

God gave us plants to directly or indirectly provide food for all of us. However, we have much to learn about God’s design in the plant kingdom, and we have only scratched the surface.

Survival Requires Change

We are entering an interesting time of change for living plants and animals on planet Earth. We are in a period of rapid climate change, and for many living things, survival requires change. However, for some life forms, this is not an issue. For example, omnivores, animals that eat a wide variety of foods, can change their diet to whatever is available. For example, bears in Alaska eat salmon, but if that is not available, they eat insects, nuts, plants, rodents, and marine shore life such as clams.

For other animals, the situation is much more complicated. For example, giant pandas rely on bamboo for food. Not only is their digestive system designed to eat only bamboo, but even their hands and fingers are designed to modify the bamboo so they can eat it. Polar bears rely on ice flows to get the seals that make up most of their diet. With much of the ice in polar areas melting, the bears cannot secure food, and starvation threatens many of them.

Survival requires change, and for some animals, that means migrating to a different place where they can find their dietary needs. As the oceans warm, cold-water fish migrate to northern areas. Some corals are establishing new colonies in different places as conditions where they have lived for centuries no longer meet their needs. On the other hand, animals with specialized equipment, such as pandas, will face extinction. Humans can step in with temporary solutions, but eventually, some forms of life will cease to exist. That is not necessarily a bad thing.

The fossil record shows us that survival requires change. A significant change in the climate caused the extinction of the dinosaurs. However, that eventually provided a climate and atmosphere where humans and the animals we depend on could thrive. Asteroid material did not directly destroy the dinosaurs, but the asteroid collision changed the climate. That change produced an environment in which dinosaurs could not survive, but it led to the formation of a climate ideal for humans.

Genesis 1:2 is an interesting passage. A possible translation of the verse is, “And the earth became wasted and emptied, and darkness was upon the face of the deep place.” That would indicate a change in Earth’s condition. God has used such changes to accomplish His will. The flood of Noah was not primarily an environmental act but a response by God to the sinfulness of humans at that time. Climatic change is another tool God has used in the past. In geologic time, there have been periods of hot and cold, and survival requires change. The current change in Earth’s climate is not solely caused by humans. We may contribute to the process, but humans are not the sole cause.

God’s creative processes don’t involve “magic tricks.” Instead, God uses natural methods to shape and mold planet Earth. Some animals, such as dinosaurs, have played essential roles in contributing to the resources that humans would need. When they had completed their mission, a change brought about their extinction. The Bible doesn’t tell us how God did what He did, but the more we study the creation, the more we understand some of His processes. Climate change has been one of them and may be so again.

The Appearance of Design

Look around, and you will see amazing things in the natural world that give the appearance of design. Atheist evolutionary biologist Richard Dawkins has said that biology is the study of things that give the appearance of having been designed. But, of course, he does not believe they were designed because he does not believe in a designer. Is he correct, or is there a better explanation for the appearance of design? Here are some links to past articles in which we have dealt with that topic:

The Problem of Beauty

Is Design in Nature an Illusion?

Designing a Planet to Support Life

Marvels of Engineering in Nature

Designed with Purpose and Beauty

What Design Looks Like

Does Intelligent Design Destroy Science?

Those are just a few of the past articles on design that show evidence for a Designer. We believe that God has given us two revelations of Himself. One is His creation, and the other is His written word. The authority of the Bible is another subject we have dealt with often. Tomorrow, we will share some links from past articles on that topic.

Slime in the Natural World

If you are around kids, you may be familiar with a toy called slime. The slime toy is a messy, oozy material that is sticky but doesn’t leave residue on your fingers. It’s slippery but has a texture that allows kids to mold it into various shapes. However, slime is more than a toy. We see different forms of slime in the natural world.

The slugs in your garden and most mollusks use slime, and the nasal mucus of a variety of animals is slime. The idea for the toy that kids love to play with originated from observing slime in the natural world. Slugs use mucus slime to lubricate their path and to stick to walls. Mollusks use slime in several ways, including making pearls. Natural slime is a highly designed material that allows animals and humans to function.

The saliva that keeps your mouth wet is one form of slime, but other forms of slime or mucus produced by your body are essential for survival. Slime in the form of mucus lubricates your esophagus so that food can go down your throat. The slime that lines your stomach protects it from acids. Slime in the natural world contains proteins called mucins. Chemists have found that animals produce mucins by adding a designed chain of amino acids to an existing protein, making it much longer.

A study into the chemistry of slime in the natural world has found some potential new uses for this material. For example, Omer Gokcumen, director of the study at the University of Buffalo, says that it may lead to new ways to treat cancer and other illnesses in the mouth and throat.

God is an incredible chemist. We see unique forms of chemistry in our bodies and the biological world around us. Gokcumen’s work focused on saliva, our first defense against pathogens, allowing us to eat various foods. Food chemistry is highly complex, and understanding how the body can handle new forms of food is becoming increasingly important. Around the world, people eat very different things than what we find in the typical American diet. Thanks to God’s design, the chemistry of slime makes it possible to feed every human on the planet.

Tale of The Lonesome Pine

Don Betts is at it again as he gives us the Tale of the Lonesome Pine.
As usual, it reflects God’s design in living things.

TALE OF THE LONESOME PINE
The tall pine lived for ages, reaching for the sky,
But as time turned the pages, it was destined to die.
Green needles are long gone, no whistling in the wind.
Bark missing here and there, declaring a final end.
The role of the tree, though its beauty is diminished,
Has time yet to see its usefulness unfinished.
Standing upright still, in a mode of decay
It serves as host to others, nature’s facets on display.
Just one observation that I’ve made recently.
Was a reservation made for a home up in that tree?
A pileated woodpecker with a mind for finding grubs
Loosened rotting bark, revealing all kinds of bugs.
The staccato of its pecking and call so clamorous
Reached a pair of feathered cousins; (amorous).
The Red Bellies pecked, and a hole was soon begun.
A western orientation had them toiling in the sun.
Working with elation, they gave it their best,
And a few days later, they prepared a nest.
Falling moss, bark, and twigs evidence the continuum.
How long will they enjoy their pine tree condominium?
A final effort to be useful will find it lying inert
Still a home for worms, God’s way of turning it to dirt.

Observing Fibonacci Day

Humans look for ways to celebrate certain days. We laugh at Groundhog Day and use Valentine’s Day for special human relationships. Some days have extensive significance, such as Thanksgiving, Christmas, or Veteran’s Day. We are now observing Fibonacci Day on November 23. Fibonacci Day is an unusual celebration of a remarkable mathematical sequence.

Fibonacci was an Italian mathematician who noticed in the year 1202 some interesting oddities about a particular sequence of numbers: 1,2,3,5,8,13,21,34,55, 89,144, 233. Notice that when you add any two sequential numbers, you get the next number. For example 5 + 8 = 13; 8 + 13 = 21; etc. If you divide two sequential numbers, you get .618034, which some mathematicians have called the “golden mean.”

Applying this Fibonacci sequence to architecture, you get a practical application. A rectangle using any two sequential numbers is aesthetically pleasing to human eyes. If you cut a square off any of these rectangles, you get another rectangle with the Fibonacci sequence. If you connect the corners of the squares in a series of Fibonacci rectangles, you get a spiral (see sketch).

An amazing thing about this is that there are an unlimited number of examples of Fibonacci spirals in the natural world. A small sampling includes:
*The spiral arms of galaxies curl in a Fibonacci spiral.
*The curl of a wave in the ocean fits the Fibonacci spiral.
*The snail shells curl in a Fibonacci curve.
*Elephant tusks curve in a Fibonacci spiral.
*The roots of human teeth curve in a Fibonacci spiral.
*Spider webs fit the Fibonacci spiral
*Keys on the piano are 5 black and 8 white, 13 in all, fitting the ratio.

*Musical chords producing pleasing sounds have the Fibonacci ratio.
*Bacteria growth curves fit the Fibonacci ratio.

There is no natural or evolutionary reason for the Fibonacci sequence. Notice it isn’t just in one discipline but in widely separated areas of study.

The Fibonacci Association publishes a magazine called the Fibonacci Quarterly, and people have written several books about the Fibonacci ratio. If you are observing Fibonacci Day, realize that this demonstrates God’s design in the creation. Chance does not produce a pattern across multiple disciplines like this.

Designing a Planet to Support Life

An interesting electronic game is one where you have access to a reservoir of materials to design a life-sustaining planet. Once you choose your materials and processes, the game computes how long life could survive on your planet. All the choices end up sterile, but the player with the longest survival time is the winner. Unfortunately, the limited number of variables causes all the options to eventually result in a lifeless globe because designing a planet to support life is a complex process.

As scientists examine systems that support life on Earth, they find multiple complex systems with some surprising agents that allow life to exist over the long haul. For example, we have written before about how many bird and mammal species spread seeds. Also, ants spread the seeds of more than 11,000 plant species. Without ants, the existence and abundance of many plant species could be impossible. A recent study has shown that other insects also spread seeds, allowing the enormous number of plant species on Earth.

Most plants have a compound called “herbivore induced plant volatiles” (HIPVs for short). A plant releases these HIPVs when caterpillars start eating its leaves. The HIPVs attract hungry predators that eat caterpillars. A recent study showed that agarwood (Aquilaria sinensis ), which is native to China, depends on hornets to spread its seeds.

Agarwood fruit produces HIPVs even though it is not assaulted by caterpillars. The agarwood HIPVs attract hornets which rush to capture the plant’s seeds. The hornets carry the seeds to their nests, where they eat the fleshy nutrient-rich structures called elaiosomes attached to the seeds. The hornets discard the seeds on the ground near their shaded nests. The seeds would dry out and die in the sun, but they germinate to produce new agarwood plants in the shade.

The Chinese people use agarwood for various purposes. However, the plant is listed as “vulnerable” because of habitat loss and the fact that local people eat the hornet larvae. Designing a planet to support life is a complex and challenging goal only God can do. Unfortunately, humans lack the wisdom to protect the life-sustaining system God has created for us.

Date Palms and Food

In our day of climate change, drought, and food shortages, it is essential to know God’s answer to these problems. The Bible talks about “a land of milk and honey.” Most of us probably think this refers to the product of bees and cows. In fact, the milk was mostly from goats, and the honey was entirely from date palms. This plant is so productive that each tree will provide 150 pounds of food a year.

Date palms can live for over 100 years and grow to the height of a five-story building. However, they grow best when the roots can find underground moisture while the tree is in arid and hot conditions above ground. That is the environment of the area where Jesus lived, and today groves of date palms grow on the edge of the Dead Sea.

Date palm seeds are so resilient that some from the time of the Dead Sea Scrolls 2000 years ago have germinated when planted and watered. In the United States, we merely call them “dates,” but there are many varieties for different uses, such as medjool, khalas, sukkary, barhi, rutab, ajwa, kimia, deglet noor, and halawi. In the Middle East, where dates have been used for over 4000 years, these varieties are well-known.

God has provided for human needs in a wide variety of ways. We can solve the problem of food shortages if we use what God has given us. Many of our staple foods in America are difficult to grow, especially in nutrient-poor soils or harsh climatic environments. Using God’s gifts wisely on a global level can reduce hunger, pain, and suffering enormously. God has given us what we need, but we must manage it intelligently.

Plant Survival and How It Works

Have you ever thought about the fact that everything in the natural world directly or indirectly eats plants? Not just animal life but bacteria, viruses, and pathogens also attack plants. So how do plants keep from being wiped out? Recent Duke University research headed by Xinnian Dong shows that similar to animals, plant survival depends on an immune system.

The difference is that animals are protected by specialized immune cells that travel through the bloodstream to a place of infection. A plant doesn’t have that means of resisting an attack. Instead of traveling immune cells, each plant cell has a built-in resistance to infection. Each cell synthesizes new proteins to attack an infection while suppressing the normal functions of photosynthesis and growth.

A plant must perform a complex balancing act. The infection will destroy the plant if it doesn’t produce enough defense proteins. If the plant produces too much defense protein, its growth will be stunted. Plant biologists are still trying to understand how plants can resist infection while still growing and carrying on their normal functions. That ability seems to be built into the design of the plant’s DNA.

Understanding the plant survival defense system and how it works will address one of humanity’s significant problems. Fifteen percent of all crops are lost to bacterial and fungal diseases, translating into some 220 billion dollars. With the growing need for food, we must find new ways to increase the productivity of plants by reducing the losses to disease.

When you look at a plant, you might think it’s a simple thing whose functions we understand. However, every plant is a showcase for the wisdom and design of God.

The Concept of Being Human

In my lifetime, the definition of the concept of being human has gone through many changes. When I was in high school, defining a human was based on the use of tools. Since then, people have observed crows, monkeys, and ants using primitive tools. Physical characteristics like brain size and erect posture fail on several fronts and, therefore, cannot be what distinguishes humans. Some have suggested that group dynamics are characteristic of humans, but bees, ants, and naked mole rats exhibit very complex group dynamics.

Scientists use the term “eusociality” for instances where colony members play various and separate roles to ensure the group’s survival. Now researchers have discovered plants that display eusociality. Dr. Kevin Burns at Victoria University of Wellington led a study of the staghorn fern Platycerium bifurcatum, an epiphytic plant. Epiphytic plants grow on other plants or trees and get their moisture and nutrients from the air. These staghorn ferns grow in colonies on trees in Australia.

Ferns reproduce by spores that originate on the fronds, which are the leaves of the ferns. The research team found that these ferns produce two types of fronds. Strap fronds are long and narrow and produce energy for the colony by photosynthesis. Some also produce spores for reproduction, but 40% do not. Nest fronds varied in size and shape and did not contribute to reproduction. Instead, they anchor the colony to the tree and provide for water and nutrient storage. In this colony of ferns, we see separate roles to ensure colony survival. With each of the roles contributing to the colony’s survival, this is an example of eusociality.

In the system of life on this planet, we see animals and even plants that do surprising things, showing design by an intelligent Creator. With that in mind, defining the concept of being human cannot be merely based on what we can do. The biblical definition of humans avoids that problem by describing humans as created in the image of God. Our spiritual makeup is what makes us unique. Our physical characteristics and what we can do physically cannot define what it means to be human. We are created in the Creator’s image, which sets us apart from the rest of the creation.
