Microbiomes in Living Tree Trunks

Microbiomes in Living Tree Trunks

A study of microbiomes in living tree trunks reveals that the woody tissues of trees contain a trillion microbial cells in addition to the actual tree cells. This includes single-celled bacteria and archaea, which are specialized for different parts of the tree and for various tree species.

The research team, led by Jonathan Gewirtzman of Yale University, studied more than 150 trees across 16 species in the northeastern United States. The trees examined included red maples, black birches, and white ashes. They discovered that microbes can live in both the outer sapwood and the inner heartwood, with each region hosting its own microbiome. Sapwood is mainly inhabited by microbes that require oxygen, while heartwood contains anaerobic microbes.

The study shows that microbiomes in living tree trunks vary from species to species. But how do these microbes get inside the trees? It might happen through wounds or openings, or they could be passed through the tree’s seeds. Perhaps, there is another route scientists have yet to discover. Regardless of the method, Gewirtzman explains, “What looks like one thing is a trillion-in-one organisms living together.”

When you see a tree, you might not realize how intricate its design is. Genesis 1:11-12 states, “Then God said, ‘Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds,’ and it was so. The land produced vegetation: plants bearing seeds according to their kinds and trees bearing fruit with seeds in it according to their kinds.”

Like many other living things, scientists are only beginning to understand the complexity of microbiomes in living tree trunks. We can recognize that there is a God through the things He has made, including trees. (See Romans 1:20.)

Why Are There So Many Species?

Why Are There So Many Species of Life?

How many species of living things exist? So far, scientists have identified, classified, and named 1.2 million species, according to worldatlas.com. The same source states there are about 8.7 million species on Earth. Nobody knows for certain, but other estimates—excluding viruses and bacteria—range from 10 million to 100 million species. Why are there so many species of living things?

How quickly are scientists discovering and describing new species? According to worldatlas.com, they identify and assign genus and species names to 15,000 to 18,000 new species each year. At that rate, if we assume 1.2 million have already been named and there are 10 million in total, the task will take over 500 years, but that’s a conservative estimate. Clearly, biologists still have a lot of work ahead.

There are between six and seven thousand known mammal species according to ourworldindata.org, . But the insect world surpasses that number. For example, beetle species alone number between 350,000 and 400,000. Each year, biologists identify most of the “new species” from museum specimens discovered earlier but not carefully studied. Some species in the wild are facing extinction, and some specimens in museums may already be extinct.

We may ask, “Why are there so many species?” God created diverse kinds of living things and endowed them with the ability to adapt to different environments. Each new species fills a niche in the incredible diversity of animal and plant life that makes our existence possible.

We have previously described the various taxonomic classifications used to categorize living things. (You can read that HERE.) “Species” is the lowest and most specific taxonomic category used by scientists to describe life forms. God created humans with an insatiable curiosity and an amazing ability to organize and categorize information. Then, He gave us plenty of life forms to study. We believe that we can learn more about God as we explore His creations. (Romans 1:20)

Neanderthal DNA and Humans

Neanderthal Fossils and Humans
Neanderthal Skull

Skeptics try to disprove the Bible by claiming that Neanderthal fossils invalidate the biblical account of humans’ special creation.

The Neanderthal story began in 1856 when remains were found in a cave in the Neander Valley, 8.1 miles east of Düsseldorf, Germany. A few years later, Charles Darwin’s work was published, and skeptics argued that the Neanderthal fossils demonstrate the truth of Darwinism. Because skepticism was popular at the time, the biblical claim that humans are created in God’s image was widely mocked.

One of the most serious implications of Darwinism was related to race. Slavery was justified by claiming blacks were mere apes and whites were more evolved. Applying “survival of the fittest,” racial prejudice reached an all-time high. As science advanced, the human genome was sequenced in 2003, and Neanderthal DNA was sequenced in 2010. This research showed that the human genome contain about 2 percent Neanderthal DNA.

The Bible does not specify what the first humans looked like, but it’s almost certain they were not blond, blue-eyed, and white-skinned. If a scientist found a skeleton of Adam, what could they know about the color of his eyes or his hair? Humans have adapted over time and climate changes, which we call “evolution.” But humans are still humans, and despite having some Neanderthal DNA, we are still created in the spiritual image of God.

Reproductive Technologies: Proceed with Caution

Reproductive Technologies: Proceed with Caution

As medical science becomes more advanced, it offers women new reproductive technologies. Older women can now have children even after menopause. Using a sperm donor, a single woman can become a mother. A woman with no eggs in her uterus can have an embryo transfer along with progesterone injections.

In vitro fertilization, which was introduced in England in 1978, has resulted in the birth of over 12 million children worldwide. The first successful egg-donor birth was also reported around that time. Efforts are underway to improve a process called in vitro gametogenesis, which involves creating gametes from stem cells and deriving an egg from another type of cell. This technique could enable same-sex couples to have children with genes from both partners. Another possibility is to develop a synthetic womb where a baby could be grown outside a woman.

The number of women choosing to have children through technological methods is increasing rapidly. What started as a way to help women who couldn’t conceive has now become an option for women of any age or situation in life to have a child. If a woman has the resources and the desire, she can pursue parenthood. One of my feminist friends has even said that males might eventually be eliminated from the planet.

There are many unknowns in this debate that make it difficult for Christians to determine where to begin. The human genome is incredibly complex, and we cannot fully understand what is in the past of a sperm or egg donor. Who is responsible if it turns out the baby has a genetic disease or a physical or mental handicap? What psychological issues arise if a child has no father figure, or if the single mother becomes sick, passes away, or changes her mind about having the child? Will older women be able to raise children to adulthood?

Humans are essentially playing “God” with something we are not equipped to control. As an adoptive parent of three children and someone who has witnessed the collateral damage of abortion, I believe we must proceed with caution in developing reproductive technologies.

Only a Mind Can Create a Mind

Only a Mind Can Create a Mind

Did the universe originate with matter or with a Mind? If matter was the starting point for all things, then we are simply matter. In that case, how can we have a mind? Are our minds just collections of cells formed from molecules that consist of atoms, which are made up of subatomic particles? Could unguided matter create our minds? Do we merely imagine that we have minds?

It seems more reasonable that a Mind was the starting point for all things. In that case, the Mind initiated the matter that formed the entire cosmos, all living things, and us. That Mind gave us minds, because only a Mind can create a mind.

The human mind has two parts working together. The physical part is what we call the brain. Materialists try to tell us that the brain is all there is. The brain handles material processes, including sensory and motor functions. It also influences emotions and memory. The other part, the soul, is not made of material substance. The soul performs abstract reasoning, makes moral choices, and exhibits free will. It is what makes us different from all other animals.

This non-material part of our mind works in conjunction with the physical brain. The brain controls our physical movements but deciding what to do is primarily under the influence of the soul. Reasoning and decision-making are activities of the soul, but damage to the brain can severely affect our ability to reason and make moral choices.

The physical and spiritual aspects of our minds must work together to make us fully functioning humans. For that reason, a person who experiences brain damage from stroke, brain cancer, severe brain injury, Alzheimer’s, or other causes struggles with abstract reasoning and decision-making. Dementia also results in loss of memory, sensory awareness, and motor skills, and it affects our emotions. However, physical factors such as fatigue and illness can also impact those things.

It’s essential to understand that despite physical impairments, whether temporary or permanent, we remain the same person with the same soul. For those suffering from dementia, regardless of its cause, loved ones need to realize that the soul, the spiritual part of that person, is still present. Malfunction of the brain makes the person seem very different, but the person’s soul is still present.   We are all made in the image of God, who is a spirit (John 4:24), not physical. We are spirits functioning within a physical body. In this life, a damaged brain can limit the functioning of a person’s soul. However, we can thank God that the soul is freed from the brain at the moment of death, and those who have accepted the salvation Jesus offers will spend a blissful eternity with Him.

The Story of Clementine Breen and Gender Transition

The Story of Clementine Breen and Gender Transition

The issue of gender transition for children is one of the great tragedies in today’s world. Not only is this a biblical issue with Genesis 2:15-24 making it clear that God’s design was a product of His wisdom and purpose, but it is a scientific issue with transgender children having a shortened life full of drugs and medical procedures. The story of Clementine Breen is an example.

A young lady named Clementine Breen is suing the medical establishment for inflicting irreversible damage upon her. She was just 12 years old when counselors and doctors told her she was really a boy. Clementine was sexually abused as a child, leaving her terrified of growing into womanhood. This led to “weird behavioral issues.”

Instead of receiving help with the damage of her past, Clementine was rushed into “transition” drugs and the removal of her healthy breasts. Medical providers scared Clementine’s parents into believing she was “high risk” for suicide. They asked her parents a cliché question we have heard many times, “Would you rather have a dead daughter or a living son?”

Doctors gave Clementine puberty blockers when she was 12 years old, testosterone at 13, and a double mastectomy at 14. During this time, her mental health worsened, and she struggled with bouts of psychosis and even attempted suicide. At age 17, Clementine was encouraged by her providers to have a hysterectomy, but she refused. In 2024, Clementine stopped taking testosterone and found a counselor who helped her understand how her past had led her to become a trans person. She is now a college student and says, “I am a woman.”

Some children have found a temporary peace with their gender change, but ultimately, the negative results of the drugs and surgeries become obvious. There is a massive need for the story of Clementine Breen to be known by families, counselors, and doctors, who must understand that gender change procedures are not a positive way to meet the needs of troubled children. Humans should not be playing God with children’s lives when the results are catastrophic.

Honey Is a Wonderful Gift

Honey Is a Wonderful Gift
Honey Is a Wonderful Gift

Honey is a wonderful gift from God, who created the agents that produce this amazing substance for our benefit. It has been a food source for people throughout history, but it is more than just food. Honey offers many health benefits, serving as an antidepressant, anticonvulsant, and anti-anxiety remedy. It has also been shown to improve memory disorders, heal wounds, and reduce allergy symptoms.

Honey is mentioned 61 times in the Bible. When God called Moses to lead the Israelites out of slavery, He described the land as “a land flowing with milk and honey” (Exodus 3:8). John the Baptist lived on locusts and honey (Matthew 3:4 & Mark 1:6). When Solomon wanted to describe the beauty he saw in his lover, he said, “Your lips drop sweetness as the honeycomb, my bride; milk and honey are under your tongue…” (Song of Solomon 4:11).

The agents God created to produce this wonderful substance are bees. It takes twelve bees their entire lifetime to make a teaspoon of honey, visiting 50 to 100 flowers daily flights to gather nectar. This incredible substance and the tiny insect that produces it are no accident of nature; they were created by God’s design. The psalmist wrote that if God’s people would listen to His words, “with honey from the rock I would satisfy you” (Psalms 81:16).

Non-Native Species and the Natural Balance

Non-Native Species and the Natural Balance - Burmese Python
Burmese Python

People often disturb the delicate balance of the natural world by transporting plants, animals, or insects from one region to another, either accidentally or intentionally. When non-native species have no predators to keep them in check, or they outcompete local species for food or space, the natural balance is disrupted. The consequences are often negative.

The list of known cases of destruction caused by non-native species is extensive. Researchers say that introducing outsiders has led to 60% of local bird, mammal, and reptile extinctions. Over the past decade, Florida has spent an estimated six million dollars to control Burmese pythons. These large snakes were brought into the U.S. and sold as pets. When they grew too big to handle, people released them into the Florida Everglades. Without natural enemies in America, these snakes have been preying on local wildlife, including alligators, domestic dogs, cats, and even cattle.

A single Japanese knotweed plant brought into the U.S. can grow rapidly, has no natural predators here, and can crowd out other species, damaging buildings and drainage systems. This plant has appeared in 43 states, including Alaska. Even viruses and bacteria have been introduced from other parts of the world. COVID-19 is one example, but there are lesser-known cases too. For instance, the West Nile virus came into the U.S. from Uganda.

The number of invasive non-native species is huge. It includes Asian carp, parachuting Joro spiders, kudzu, giant hornets, sea lampreys, zebra mussels, South African red weevils, red swamp crayfish, and starlings, among others.

The U.S. government spends over three billion dollars annually on managing invasive species, and more than $150 billion yearly on agricultural damages. Globally, the bill reaches $423 billion. All of this stems from humans acting as poor stewards of the natural resources God has given us.

Itching and Scratching Design

Itching and Scratching Design

Summer brings insect bites and chemical irritation from certain plants. Insect bites or touching poison ivy or another irritating plant activate a series of itching and scratching. Why do we scratch? Why does it feel good? And why does scratching sometimes make the problem worse?

When we scratch, we cause an increase in blood flow to the area, which temporarily eases the itching. Scratching causes a mild soreness that distracts us from the itch. It also activates the brain’s reward system—the same system involved in addiction. The brain releases the happiness hormone serotonin, which increases the desire to scratch even more. This can lead to skin damage and inflammation, turning a minor itch into a bigger problem.

Scientists are exploring the complex system of itching and scratching. Although itching is closely related to pain, researchers have discovered cells in the spinal cord that transmit itch signals separately from pain signals. Both pain and itching have beneficial and harmful effects.

The complexity of our bodies shows evidence of design, not accident. Itching and scratching are designed to cause us to react to external attacks on our bodies, removing the effect of irritants and producing new epidermal cells. This is another demonstration of the truth of Psalms 139:14: “I will praise you, God, for I am fearfully and wonderfully made; your works are wonderful…”

Cowbird Mystery Solved

Cowbird Mystery Solved
Brown Headed Cowbird

Cowbirds are quite unique among birds. A female cowbird lays her eggs in another bird’s nest. The parent birds there raise the cowbird chicks as their own, even if they are smaller than the cowbird. The cowbird mystery is how the bird, raised among a different species, finds a mate.

Recent studies have offered an answer. About a month after hatching, the young cowbird leaves the foster parent’s territory. It then encounters adult cowbirds and instinctively follows them. The foster parent does not help with this process, but their behavior allows cowbirds to reproduce.

The scientific term for the cowbird’s behavior is “brood parasitism.” Although the cowbird mystery may seem like an unusual way to reproduce, it helps maintain balance in the bird world. God’s creation has many mysteries we don’t yet understand, but as we learn more, we see the wisdom behind it. This reminds us of Romans 1:20, which states that we can know there is a God through the things He has made.
