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.

How Frogs Swallow Their Prey

Most of us know that frogs extend their tongues which stick to their prey, and then draw it back into their mouths. High-speed videos show that frogs unroll their tongues like party horns and wrap their targets in an adhesive hug. What science has not understood is how frogs swallow. What happens when they close their mouths? Rachel Keeffe is a National Science Foundation Graduate Research Fellow who has released a study showing how frogs process whatever their tongues bring into their mouths.

Keeffe and her colleagues attached metallic beads at various points in the mouths of cane toads, among the largest frog species. They wanted to study what happens to food once it is in the frog’s mouth. There is a very complex system of cartilage and muscles traveling so far down the frog’s throat that it butts up against the heart. Once there, chemicals secreted in a stomach-like chamber digest it, bringing the nutrients into the frog’s vascular system.

When we examine how frogs swallow, we see that even the simplest life forms have highly complex systems. Frogs control insects and other forms of life that threaten humans. In turn, a variety of birds and fish eat frogs. The world around us speaks volumes of God’s wisdom and design, allowing life to exist on Earth. Romans 1:20 tells us that we can know there is a God through the things He has made. We see that again in the design of how frogs swallow.

Our Unique Planet with Continents

Many things make planet Earth unique, including a life-supporting atmosphere, a large moon, a protective magnetic field, and continents. As far as we know, no other planet has silica-rich continental masses surrounded by liquid water. In these and many other ways, our unique planet with continents is like no other.

So, why do we have continents? Many factors make the continents possible. They include plate tectonics, volcanism, abundant liquid water, and even plant life. It also has something to do with the minerals. Other rocky planets that we are aware of have basalt on their surfaces. Earth’s basalt is mainly on the ocean floor. The continents are made of lighter materials, including granite, sandstone, gneiss, and slate. The continents also have volcanic rocks, cooled magma, and sediment.

Earth’s continents sit high because they are thicker and less dense, making them buoyant enough to sit on top of the basalt. Like other floating masses, the continental plates gradually move. Sometimes they have collided, causing their edges to rise, forming mountain ranges. The granite weathers and breaks down into sand and clay forming fertile land. Tectonic plate collisions formed the Appalachian mountains, which have weathered to become much lower than they originally were.

On the other hand, the Himalayas formed when the Indian Subcontinent pushed north, colliding with Asia. That northward movement is still at work, causing the Himalayas to grow faster than they are eroding. Other mountains formed through volcanic activity. The ash from that volcanism has created fertile areas for crops and vegetation.

Many factors working together create fertile continents suitable for life. Earth is a unique, constantly changing, life-supporting planet of continents surrounded by oceans that temper the climate and supply rain to water the land. From all that science can determine, there is no other planet like it!

Are all the factors that make Earth the ideal place to live just accidental coincidences or do they show design? We cannot explain the vast number of coincidences by chance. We see that our Creator gave us everything we need for life and put us here to serve Him. We have much to be thankful for and a great responsibility to protect God’s great gift to us. Leaving our unique planet with continents to move to another one is not a viable option.

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.

Can Evolution Explain Life?

Over the past two days, we have considered dinosaurs and the age of planet Earth. Some suggest that accepting that Earth is ancient means that evolution explains life. Can evolution explain life? “Evolution” is a very broad term that can mean many different things. However, we have said before that evolution can’t explain everything. Here are some links to examine:

I Believe in Evolution

Evolution Has Multiple Meanings

Evolution Is Not Creation

Human Evolution from Lower Life Forms

Fossil Apes and Human Evolution

Biological Barriers to Evolution

Evolution Does Not Explain Creation

These links are only a sample of the many articles we have published on the topic of evolution. You can go to our DoesGodExist.today website and use the search box to find articles on this or other topics. Can evolution explain life? The short answer is “no.” Naturalistic evolution also cannot explain the apparent design we see in nature, and we will deal with that tomorrow.

Unstable Wing Design Is Essential

“How do birds fly?” is a very old question that remains basically unanswered. We aren’t talking about simple fixed-wing flight, which uses the old physics model that a rapidly moving fluid exerts minimum pressure at a right angle to the direction of motion. We use that model for airplanes, but birds have another feature called unstable wing design. The unanswered question about bird flight is how they can be so agile. Drones have a problem with this issue because, with their fixed-wing structure, they can’t make quick direction changes.

Christina Harvey of the University of California, Davis, and Daniel Inman of the University of Michigan have examined the flight dynamics of 22 bird species. They concluded that unstable wing design is the key to what birds can do. For example, seagulls can change the shape of their wings by adjusting their wrist and elbow joints. Changing their wing shape allows them to handle wind gusts easily. Aerospace engineers have not been able to duplicate that part of flight dynamics, but most bird species manage it quite well.

Drones working in an urban environment must handle sudden wind gusts and rapid direction changes, but with a fixed-wing design, that is almost impossible. The study’s authors point out that future business-level drones or personal aircraft must be able to implement unstable wing design. However, engineers have yet to find a way to do that. Researchers funded by the National Science Foundation (NSF) and the National Academy of Science (NAS) are working to understand how the complex design of bird wings allows unstable flight.

It is fascinating that the earliest birds of flight seen in the fossil record had a wing design that allowed unstable flight. We even find fossil birds that resemble our modern hummingbirds, which have very unstable wing design. We continue to see examples of intelligence in the design of living things. Much of what you and I enjoy, from velcro to rockets and modern aircraft, had their start when thinking people saw the design God built into life and copied it to benefit all of us.

Alien Minerals and Alien Life

Andrew Locock at the University of Alberta discovered two new minerals in a fragment of the El Ali meteorite that landed in Somalia. These minerals had never been found naturally on Earth, although scientists had synthesized them in a lab. Chris Herd, an Earth and Atmospheric Sciences professor and curator of the University of Alberta’s meteorite collection, named the two alien minerals “Elaliite” and “Elkinstantonite.”

The tabloids try to use this find to suggest that alien worlds exist that are radically different from Earth. The fact is that these minerals contain the common elements iron, potassium, and oxygen. Like many other “alien minerals” such as Brianite, Xifengite, and Heamanite, scientists have synthesized them. Inorganic materials can form new chemical configurations when they are subjected to temperatures and pressures not seen on Earth’s surface. All of these minerals with unfamiliar names are the product of conditions not present on the surface of our planet.

There are chemical restraints on what elements can sustain life. Biologists tell us that life is “that form that can move, breathe. respond to outside stimuli, and reproduce.” The elements that make those functions possible are carbon, hydrogen, oxygen, and nitrogen. For example, living things made of iron are not chemically possible, yet iron is the dominant element in meteorites. Oxygen is the one oxidizing element that allows respiration without adverse chemical reactions that would prevent life from surviving. For that reason, life forms breathing chlorine or bromine are not possible.

At the same time, alien minerals in meteorites do not mean that alien life is impossible. On the contrary, if there is life in space, it will be made of the same elements that we are. It may not look like us or live as we do, but we will not have any trouble identifying it as life.

Every time this issue comes up, it reminds me of my experience on a radio show. I was in Washington, D.C., doing a call-in talk show with Larry King (before he became famous) and a local atheist. We had a lively discussion about science and faith with some references to alien life. A caller said to the atheist, “What would you do if a spaceship landed on the White House Lawn and a little green man jumped out with a Bible in his hand and said, ‘Has Jesus been here yet?’” Before I could point out some problems with that proposal, my atheist opponent looked at me, smiled, and said, “Punt.” Larry King responded by going to a commercial.

Sweaters for Squirrels

I got a call from a lady who was making sweaters for squirrels. She was concerned that the cold weather would make the squirrels shiver and get sick if they didn’t have protection. I tried to tell her that her heart was in the right place, but God had already made wonderful coats for the squirrels. Because of that, they do not require winter clothing to add to what God had already given them. That led to a discussion of birds who didn’t have fur coats. I asked her if she knew about goose down, and she admitted she had a goose down winter coat. “But those poor little birds on my feeder don’t have down,” she replied, “and I have seen them shiver.” Sweaters for birds seem to be more problematic than sweaters for squirrels.

That exchange started me thinking about the many ways God has equipped living things for cold climates like the one here in Michigan. When I taught physics in the public high schools of South Bend, Indiana, we covered conduction, convection, and radiation. I began the discussion on conduction by asking why we wear clothes, outside of the obvious one. The thermal conductivity of various kinds of clothing helps us stay warm in winter and cool in summer. For example, goose down is a good insulator because it holds pockets of air, and air does not conduct heat well. Likewise, the design of skin and hair involves thermal conductivity, which is why being immersed in cold water takes heat out of our bodies rapidly, causing hypothermia.

Fat is another insulating material, and having very little fat in one’s body can cause rapid heat loss. Even the color of one’s skin or hair can make a difference. One of the experiments that I had my students do was to take two identical cans and paint one black and the other white. We would then put boiling water in each can and measure the temperature of the can every minute, graphing the cooling curve of the two cans. The black can would cool much faster than the white can; in this case, the cooling is by radiation, another heat transfer method. We all know that black objects absorb heat from sunlight better than white objects. Therefore, black things also release heat more rapidly.

The physics of heat transfer is another design feature built into living things. All animals are designed with the right equipment to survive in their natural environment. That is why we don’t need to make sweaters for squirrels. However, when humans move animals to a radically different climate, the result can be dangerous.

Climate change is causing some animals to migrate to latitudes where their survival is not threatened. That is also a design feature of life. In Job 39, God challenges Job with questions about design features in living things. We are only now beginning to understand the answers to some of those questions.

How Fast Are You Moving?

If I asked, “How fast are you moving?” you might reply that you are sitting still. However, don’t forget that you are sitting on a planet that is spinning on its axis. A fixed observer in space would say that you are moving with the planet’s rotation at up to 1000 miles per hour if you are close to the equator. At the same time, Earth is revolving around the Sun at roughly 66,000 miles per hour. The Sun is one of 100 billion stars rotating around a black hole at the core of the Milky Way galaxy at approximately 400,000 miles per hour. Meanwhile, the galaxy is moving through space at around 2,200,000 miles per hour. So, how fast are you moving when viewed from a fixed point in space?

The amazing thing about the creation is that each of these numbers is critical for our survival. The spin of the Earth on its axis distributes heat in a way that we are not frozen or burned up. The revolution around the Sun keeps us from being drawn into the Sun or slung into outer space and frozen. The movement of the Sun around the galactic core prevents the black hole at the center of our galaxy from sucking in the entire solar system and destroying it. The galaxy’s movement through space prevents it from being absorbed by another galaxy. The speeds are critically fine-tuned because there is no tolerance for error.

As astronomers look at other solar systems and galaxies, they see the speeds that allow us to exist are not that common in space. The simple statement of Psalms 19 that “the heavens declare the glory of God, and the sky above shows His handiwork” reminds us that we are not the product of an accident. The more we learn about the cosmos, the more obvious it becomes that our existence is a product of intelligent design.

The psalmist also reminds us of the astonishing fact that the Creator cares about us. “When I consider your heavens, the work of your fingers, the moon and stars which you have ordained, what is man, that you are mindful of him …” (Psalms 8:3-4). So how fast are you moving right now? Fast enough to exist and to know that there is a reason for that existence. Read Job 1 and 2 and Ephesians 3:9-11 and 6:12 to learn more about that reason.
