Newly Discovered Plant Communication Method

This isn’t a new method plants use to communicate with each other, because they have been using it for who knows how long. But for scientists, it’s a newly discovered plant communication method.

The natural world is filled with astonishing forms of communication, and plants are no exception. We have mentioned before that plants communicate underground with the aid of fungi and mycorrhizal networks in what some have called the “woods-wide-web.” They also communicate by releasing chemicals into the air. We have even seen that they communicate with insects by means of sounds. Plant communication does not involve images, spoken words, or written texts, but can still be considered communication.

Plants communicate primarily through chemical signals. When a plant experiences stress—such as an attack by herbivorous insects—it may release volatile organic compounds (VOCs) into the air. These airborne chemicals can be detected by neighboring plants, which may then activate their own defense mechanisms preemptively. This method of plant communication has sometimes been described as “eavesdropping.”

The newly discovered plant communication method involves electrical signals passing from plant to plant when leaves touch. Ron Mittler and colleagues at the University of Missouri in Columbia experimented by growing thale cress (Arabidopsis thaliana). They grew some plants in isolation and some in dense patches where the leaves touched. Then they stressed the plants by exposing them to excess light. The plants that were grouped together showed less stress damage than the ones in isolation. The researchers analyzed gene expression in isolated plants and in plants that were touching. They also monitored signals passed between the grouped pants.

According to the report, the plants with leaves touching activated over 2,000 stress-response genes that could help to protect them from excess light, cold, salinity, and wounding. The isolated plants showed greater cell damage under stressful conditions.

Understanding plant communication opens new doors for agriculture, conservation, and our appreciation of design in the natural world. Mittler hopes that this newly discovered plant communication method may be used to design mixed plant communities that are more resilient, perhaps reducing the need for chemical pesticides or fertilizers. We believe that God has given us the tools and the talent to reveal new strategies for ecosystem management and food production.

Orphan Genes Challenge Darwinism

The DNA in every cell in your body is made up of shorter strands called genes, which contain the instructions to produce various proteins. Neo-Darwinian evolutionary scientists look for genes with very similar sequences to others to show that one gene evolved from another through random genetic mutations. However, researchers are discovering genes that don’t resemble any other known gene. The technical term for these is taxonomically restricted genes (TRGs). These so-called orphan genes challenge Darwinism.

If all of life evolved from a common ancestor through small genetic mutations, orphan genes don’t fit this model. They either shouldn’t exist or should be extremely rare. A few years ago, evolutionists argued that only a small percentage of species’ DNA had been sequenced, and that with more research, the mystery of orphan genes would be resolved. However, the number of orphan genes continues to grow. The trend indicates that orphan genes challenge Darwinism.

Even closely related species that share a common trait can have their own unique orphan genes. In other words, the evidence does not support gradual changes caused by small mutations but instead points to entirely new, unique genes that have not been seen before. Evolutionists respond by saying natural selection can explain this, but they are unable to specify how. The research continues, but for now, it seems to me like an “evolution-of-the-gaps” argument.

As Jonathan Witt wrote in Salvo magazine, “Our uniform and repeated experience tells us that generating significant amounts of novel, functional information doesn’t happen by chance. It requires a mind. Our uniform experience tells us this, and probability calculations applied to everything from English text and software code to DNA confirm it.”

It’s safe to say that orphan genes challenge Darwinism and will likely continue to do so.

Origin-of-Life Theories and Archaea

Scientists aim to answer several very difficult questions about origins. Two of these questions relate to the origins of life and complex life. Some scientists believe they are getting closer to discovering how complex life developed from simple life, and the media often sensationalizes any origin-of-life theories.

Living things are classified into three domains. We are very familiar with multicellular life, which includes plants, animals, and people. That is the domain of eukarya, or complex life. There are two domains of single-celled life—bacteria and archaea. Most people are more familiar with bacteria than archaea. Scientists did not recognize how distinct archaea are from bacteria until the 1970s, when DNA analysis began.

The cells of bacteria and archaea are relatively simple and small compared to eukaryotic cells, which have a nucleus, mitochondria to supply energy, and other internal structures. In the 1960s, one group of microbiologists described the gap between eukaryotes and the single-celled bacteria and archaea as “the greatest single evolutionary discontinuity to be found in the present-day world.” Evolutionists seeking origin-of-life theories had to find a way to bridge this very wide gap.

In 2008, researchers discovered a new type of archaea living in hydrothermal vents on the Atlantic Mid-Ocean Ridge. They said these archaea “seemed to be somehow closer to eukaryotes than what we knew before.” In 2015, a paper published in the journal Nature described them as “the closest known living relatives of eukaryotes,” creating a scientific sensation. Their genomes were said to contain genes that are “hallmarks of eukaryotes.”

Scientists theorized that the Asgard archaea, as they came to be called, absorbed bacteria that became mitochondria, but there was still no evidence of a nucleus. Research and debate on this are expected to continue for years, but it has sparked new speculation about extraterrestrial life. Some have suggested that unicellular life on other planets could evolve into eukaryotic, advanced life. But that assumes there is unicellular life on other planets.

Scientists proposing origin-of-life theories still have no idea how non-living matter could turn into living, reproducing cells. Be cautious when you see media stories about scientists being close to discovering the origin of life or the origin of complex life. Even simple cells are far too complex to have arisen by chance without a Designer.

Kelp Forests Enrich the Earth

In our era of environmental threats, it’s reassuring to know there are solutions to some of the problems we face. God has created a form of life that purifies water and the atmosphere from pollutants, including human-made toxins and carbon emissions. At the same time, it supplies nutrients for marine life. We find this solution in the ocean’s kelp forests.

Kelp forests are 20 times more effective at absorbing carbon dioxide than similarly sized land-based forests. Kelp is plentiful along the west coast of the United States and grows on the coasts of Maine, Long Island, the United Kingdom, Norway, Tasmania, southern Africa, Argentina, and Japan. Kelp supports over 1000 species of marine plants and animals and provides roughly half of the oxygen we breathe. Kelp can also be used to make alternatives to plastics and chemical fertilizers used in agriculture. It can grow almost anywhere, including on abandoned oil rigs along various coastlines.

The Genesis account does not mention ocean life forms because the Fertile Crescent was far from an ocean coastline. Just as God knew humans would need coal, iron, copper, and other minerals, He provided kelp forests to shape the Earth for human survival. Science helps us understand how dinosaurs, diatoms, and many other animal forms not described in Genesis were God’s tools to prepare Earth for humans. We are in awe of God’s wisdom and creative power.

Bamboo Alarm Clock

Although bamboo grows in forests and can look like trees, it is actually the largest type of grass. Bamboos are also the fastest-growing plants in the world, with some growing 3 feet (91 cm) in just 24 hours! The most fascinating thing about this unique grass is the bamboo alarm clock.

Bamboo is an important building material in many parts of Asia because it has a higher compressive strength than wood, brick, or concrete, and a tensile strength that rivals steel. But perhaps the most interesting aspect of bamboo is its reproductive method, often called mass, gregarious, or synchronized flowering—the bamboo alarm clock.

Bamboo doesn’t flower or produce seeds every year. Depending on the species, it may take 20, 35, 65, or even 120 years to flower. Then, the entire forest blooms, produces seeds, and dies all at once. Even more amazing is that if you take one plant from the forest and move it halfway around the world to a different climate, it will still flower at the same time. Even if you transplant it just a few weeks before its normal bloom time, it will still flower, produce seeds, and die at the same time as its original neighbors.

This raises two questions: “Why?” and “How?” Survival needs may explain the “why.” Synchronized flowering ensures effective pollination. They flood the air with pollen, so even isolated plants have a high chance of pollination, as the pollen cloud can travel hundreds of miles. Additionally, synchronized pollination and fruiting prevent predators from consuming all the fruit, securing the species’ survival.

Scientists are still trying to understand the “how” behind the bamboo alarm clock. Various theories have been proposed and dismissed. What we do know for sure is that bamboo has an internal clock that signals when it is time to reproduce. Only the Creator fully understands how this mechanism works. All we can do is marvel at this system’s design, as it seems impossible to be purely the result of chance.

Inside a Tree Trunk

There is so much about the everyday things in our lives that we don’t understand. When we see a tree, we have no idea what lives inside that tree’s trunk. Recent studies by scientists have found that inside a tree trunk there are entire communities of bacteria. A single mature tree hosts about one trillion bacteria, with different communities living in various layers.

What is especially remarkable is that some of the bacteria living deep inside a tree trunk are anaerobic, meaning they don’t need oxygen and produce methane. The outer layers of wood may absorb some of the methane, but more research is needed on that. The study’s lead author said that the inside of a tree trunk is more like a wetland, where anaerobic bacteria and methane producers thrive in low-oxygen environments.

Poets like Robert Frost and Joyce Kilmer have written famous poems about trees. While we admire the beauty of a tree and enjoy its leaves and their fall colors when they lose chlorophyll and turn vibrant, we often don’t think about what it takes to create them. In a desert, humans seek an oasis where conditions permit trees to grow. Most of the time, we take trees for granted and never consider what’s inside a tree trunk.

Genesis 1:12 tells us that God formed trees (the Hebrew word “ets”) as a special creation, separate from grasses or gymnosperms. That simple statement hides how complex it really is to make a tree trunk. As Romans 1:12 states, “We can know there is a God through the things He has made,” and the trees we see in our yard or garden demonstrate how much intelligence is needed to create a simple piece of wood.

Female Moths Listen to Plants

For years, scientists have known that plants vibrate at ultrasonic frequencies when their internal water pressure changes. Recently, they learned that drought-stressed plants or plants that have been cut produce ultrasonic sounds loud enough to be detected by a moth’s ultrasonic hearing. Dr. Yossi Yovel and a team of researchers at Tel Aviv University took this a step further to see whether female moths listen to plants and avoid laying their eggs on those that are distressed.

The researchers found that female Egyptian cotton leafworm moths avoided laying eggs on tomato plants that made distress-related sounds. Unhealthy plants do not allow the moth larvae to thrive. The sounds plants make when they are distressed or unhealthy are outside of the range of human hearing, but insects, bats, and even some small mammals can hear them.

Learning that female moths listen to plants, Professor Yovel speculates on whether “all sorts of animals will make decisions based on the sounds they hear from plants, such as whether to pollinate or hide inside them, or eat the plant.” Taking this even further, Dr. Lilach Hadany, also of Tel Aviv University, speculates on whether plants can pass information to each other through sounds and act on those sounds. “This is an exciting question,” she told BBC News. Previously, researchers learned that plants can communicate with each other through their roots.

The researchers, however, emphasize that plants are not sentient and that this interaction cannot be considered “communication” in the “conservative definition of the term.” Nonetheless, we can look at our own bodies and recall the statement of David in Psalms 139:14, “I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well.” Likewise, we see that other forms of life are “fearfully and wonderfully made” as well. Everywhere we look in the natural world, we see evidence of a wonder-working hand that has gone before.

Hammer Orchid and Thynnid Wasp

Ten species of hammer orchids (genus Drakaea) are found only in Western Australia, and each is pollinated by a specific wasp species in the Thynnid family. Each orchid has a fake model of the pollinating wasp carefully placed to attract the real wasps. It sounds like a clever practical joke, but the hammer orchid has a “dummy” labellum on a stem attached to a hinge that only bends toward the orchid’s flower.

Of course, the dummy on the stem resembles a female thynnid wasp in size, shape, and color. At the right time for fertilization, the hammer orchid releases a pheromone that mimics the female wasp’s scent. Thynnid wasps are unusual because the female is flightless and waits on a stem or grass blade for a male wasp to carry her away to a food source for mating. When a male thynnid wasp falls for the trick and tries to carry away the dummy, a hinge throws him backward into the orchid, dusting him with pollen.

The humiliated male wasp then leaves and might be fooled by another hammer orchid, where he deposits the pollen he collected from the first flower. The male wasp might repeat this process several times (assuming he’s a slow learner), which is the only way the orchid gets pollinated. If the trick didn’t work, the hammer orchid would become extinct.

Consider all the things that must go right for this trick to succeed:

1. The orchid must produce a labellum that resembles the female wasp in size, color, and shape.

2. The male wasp must be programmed to grab a flightless female and carry her away as part of the mating ritual.

3. The orchid must produce the right complex chemical pheromone to mimic the female wasp at just the right time to attract the male.

4. The hinge must move in the right direction and not be too weak or too stiff.

5. The stem from the hinge to the dummy wasp must be exactly the right length to coat the male wasp with pollen.

6. The male wasp must not be clever enough to learn from his mistakes.

Could the unique design of the hammer orchid have happened by chance, or is design a better explanation? Could it also be that the Designer has a sense of humor?

Biosphere 2 and Primary Succession

Beginning in 1987, a new glass and metal structure began to rise in the desert near Oracle, Arizona. In 1991, it opened as the world’s largest closed ecological system. It was called “Biosphere 2” because planet Earth is “Biosphere 1.” The idea behind the project was to test whether a closed system could support human life on another planet. This marked the start of a two-year mission in which eight people were isolated inside this artificial biosphere to simulate life on a space colony.

The experiment in Biosphere 2 ran from 1991 to 1993 with only limited success. It was attempted again for six months in 1994. Both attempts encountered technical issues and the strain of human group dynamics. Additionally, during the second try, the company managing the experiment was dissolved, leaving the project in limbo. Initially, Columbia University took control of the facility and used it for scientific research until 2003. When it seemed Biosphere 2 might be demolished for urban development, the University of Arizona (UA) took over in 2007 and gained full ownership in 2011.

Today, about 100,000 tourists visit Biosphere 2 each year while UA continues to conduct experiments there. One of the experimental areas is the Landscape Evolution Observatory (LEO). It consists of three artificial landscapes, each measuring 30 by 11 meters with a 4-meter depth of crushed basalt rock from a volcanic crater in northern Arizona. The scientists aim to observe how these landscapes change “from purely mineral and abiotic substrate to living, breathing landscapes that will ultimately support microbial and vascular plant communities” (UA’s words).

I wonder how the researchers could be sure that the one million pounds of basalt from a volcanic crater could be “abiotic,” meaning free of any life forms. However, if microbes or seeds are present, I believe the landscapes will “evolve.” The key is that for any life to develop, it must already be there. Evolution is change over time, but the development of life requires initial life to exist.

The UA scientists explain that the evolution of cyanobacteria—the first microscopic organisms to use photosynthesis—pumped oxygen into the atmosphere, facilitating the development of aerobic life. This paved the way for multicellular life, an ozone layer to shield life from harmful ultraviolet radiation, and weathering to break down rocks into soil.

Considering the history of Biosphere 2, I doubt it will be around—or that the scientists will be—long enough to observe significant evolution. It takes time for rocks to break down into soil. They describe the “process of primary succession,” where simple microbes expand into organisms of increasing “complexity and biodiversity.” The researchers state that photosynthesizing cyanobacteria will capture nitrogen from the air, preparing the way for mosses to grow. The next step involves “colonization by larger plants with roots,” and the primary succession continues.

Long before Biosphere 2, Genesis 1:11-12 details the process of primary succession: “And God said, Let the earth bring forth grass” (Hebrew deshe, meaning tender grass such as lichen or algae), “the herb yielding seed” (Hebrew eseb, meaning naked seed or gymnosperm), “and the tree yielding fruit” (Hebrew ets, meaning tree, wood, or timber). The process of primary succession then continues. (For more on this, see John N. Clayton’s booklet “God’s Revelation in His Rocks and His Word.”)

As the UA scientists describe in their explanation of LEO, “The Earth system consisting of air, water, soil, plants, and microbes is a complex, interacting system.” And so it is, as God revealed to Moses thousands of years ago. Complex, interacting systems require an intelligent Designer.

Shark-Skin Biomimicry

Human engineers often draw inspiration from the natural world. When they adapt these designs for human use, it’s called biomimicry. Shark-skin biomimicry utilizes the design principles that enable sharks to move smoothly and quickly through water, applying them for industrial and practical purposes.

In addition to its body shape, a shark’s ability to swim swiftly and quietly through the water is largely due to the design of their skin. Shark skin has a textured pattern, known as riblets, that helps reduce water drag. Researchers at U.C. Berkeley and MIT explored ways to adapt this shark skin design to reduce the water’s drag on towed sonar arrays (TSAs) used by ships and submarines. They discovered that rectangular riblets could cut drag by 5% or more and reduce noise by 14%. Noise reduction is very important for sonar, which depends on detecting sound echoes. Less noise also benefits marine wildlife.

Another application of shark-skin design is in water distribution systems. Biomimetic riblets inside water pipes can lessen turbulence as water flows through. Reducing turbulence and drag decreases the energy needed to pump water to its destination. This means lower costs for supplying water to homes. Researchers found that, under ideal conditions, drag can be cut by up to 10%.

According to another study, shark-skin biomimicry can also improve the efficiency of microchannel heat sinks. Microelectronic components in computers and other devices can be damaged by heat. The researchers reported that “the shark-skin based bionic structure had higher heat transfer capacity and lower friction loss.”

Looking at nature’s designs reveals wisdom at work. Shark-skin biomimicry offers benefits in aviation, marine transportation, water systems, and the cooling of microelectronics. What other new applications of biomimicry are still to be discovered? God’s wisdom shows in what He has made. Humans have no excuse for failing to recognize His eternal power and divine nature (Romans 1:20).
