Mysterious Denisovans and Anthropology

Mysterious Denisovans - Anthropologist finding Human Skull

Over ten years ago, scientists found some human remains in Siberia’s Denisova Cave. They looked different from any human remains known at the time. Scientists have continued to study the mysterious Denisovans.

The past year of 2019 turned out to be a banner year for more data on these ancient humans. A breakthrough came with more remains that have been found in Tibet. Genetic evidence relates these specimens to humans in East Asia, Indonesia, and Papua New Guinea. New genetic studies show that there are Denisovan genes in Neandertal and Homo sapiens. Paleogeneticist E. Andrew Bennett says that there is no doubt that interbreeding occurred among all of these ancient humans.

The biblical account tells us that all humans on Earth came from a single ancestor. The Hebrew word translated Adam literally means “of the ground,” and the description of that first human is not dated or timed. The biblical point that all humans came from one, simply means that there are no different species of humans. The variations in the human genome are racial. They show the adaption to various climates, altitudes, and diets. Bennett says, “It is better to talk about different populations, not different species.” The mysterious Denisovans are merely another population of humans.

Is Design In Nature An Illusion?

Is design in nature an illusion? That is an important question to consider. Atheists continue to parrot the claim of Richard Dawkins in his book “The Blind Watchmaker” (page 1). Dawkins wrote that “the study of complicated things that give the appearance of having been designed for a purpose” is actually an illusion.

Dr. Marcos Eberlin summarized that view in this way: “We are supposed to believe that all we see is an illusion, and that, in reality, a process unguided by anything except the laws and constants of nature formed all we know – the universe, the stars, the ocean, the sky and clouds, RNA and DNA, ribosomes, bacteria, fish, birds, chimpanzees and us.”

Illusions are not science. Illusions cannot be tested or falsified in any way, and that makes them attractive as an explanation to avoid admitting God’s existence. The problem for atheists is that the processes we see in the natural world are interdependent. The body’s immune system, for example, requires the existence of a dozen other systems to function. Numerous chemical and biochemical processes have to be in place. The clotting mechanism of the body has to be working. Sensory systems have to be functional. All of that has to be present before life comes into existence or disease, and infection would destroy the organism as quickly as it was formed. Biochemistry and biology have gone through incredible increases in understanding in recent years. The interdependence of systems is becoming more and more evident as new discoveries are made.

In 2016, the Royal Society of London held a conference to discuss “calls for revision of the standard theory of evolution, recognizing that the issues involved remain hotly contested.” Materialistic philosophical views have constrained science and narrowed our horizons, according to Dr. Eberlin. The illusion theory is not supported by statistics applied to the probability of changes in the history of the formation of planet Earth or of life on earth.

Is design in nature an illusion? No, complexity can not be discarded by simply applying the label of “illusion” to it. Life and the creation are real.

Playing God With DNA Doesn’t Work

Playing God With DNA Doesn't Work

One of the promises of modern genetics is that in the future, we will create “designer babies.” The idea is that if you produce a group of embryos and then look at the DNA of each of them, you can select which embryo you want to become your child. The other embryos would be destroyed. The process is called “preimplantation genetic diagnosis (PGD).” You might call it playing God with DNA.

With PGD, the embryos are created through in vitro fertilization. Technicians remove a single cell from each embryo and test it for single-gene variants which cause cystic fibrosis, Tay-Sachs, or other diseases. Many diseases such as diabetes may result from variants in hundreds or thousands of genes. The risk for heart disease may involve millions of gene variants.

Medical scientists are working to establish a polygenic score, which would indicate intelligence, height, and other traits by examining the DNA. They call these factors “enhancements.” The problem is that those traits may also be the result of multiple genetic variants. Playing God by trying to select the attributes for a “designer baby” can be not only immoral but dangerous.

A group of researchers published a study in the journal Cell on November 21, 2019, in which they attempted to learn how reliable polygenic scores would be for determining height or IQ. The research indicates that the DNA genetic predictions about those enhancements are unreliable and insignificant at best. Among other problems is that “differences in diet, lifestyle, exposure to pollution, culture, undiscovered genetic variants, and other unknown factors can influence how complex traits develop.”

The original use of polygenic scores was to help people know if a lethal or disruptive disease was a part of their heredity. Being able to repair the DNA or choosing not to have children is an option that would be useful to couples. Embryo selection for non-medical traits such as height, intelligence, or gender is a whole different question.

An article on this study in ScienceNews.org quoted Dr. Nicholas Katsanis, who is a human geneticist at the Lurie Children’s Hospital of Chicago. Dr. Katsanis said, “The idea that we’re going to do genetic screening for anything other than medically actionable items is the definition of eugenics. That we’re even contemplating this is disturbing.”

We agree that humans playing God in areas like this is immoral and likely to be disastrous at worst and disappointing at best.

Evolution Experiments and their Results

Evolution Experiments and their Results

What if we could speed up time to test the concept of evolution? A scientist can’t wait millions or billions of years to study the process of natural selection as it creates new creatures. With that in mind, science must devise evolution experiments to study many generations in a much shorter time.

More than thirty years ago, Richard Lenski, who teaches at Michigan State University, began a project to study the evolution of the bacteria Escherichia coli, commonly known as E. coli. The project is called the Long-Term Evolution Experiment (LTEE). The scientist and his assistants carefully track the naturally-occurring random mutations in succeeding generations of E. coli. The environment for the bacteria is optimized for these one-cell creatures to grow and reproduce. Mutations are often harmful, but sometimes beneficial mutations lead to an improvement in the bacteria’s reproductive ability. Natural selection removes the bacteria with harmful mutations while those with beneficial mutations become more fit and reproduce. It’s what we call survival of the fittest.

Since 1988, the evolution experiment has continued, and scientists have kept careful records of the changes. Since the generation period of these bacteria is much shorter than that of humans, the study has gone through 70,000 generations. That is equivalent to more than 1.75 million years of human generations.

Through thousands of generations, there have been billions of mutations. Beneficial mutations that have lasted and accumulated amount to dozens. It is interesting that as time passes, successful mutations become increasingly rare. What the scientists are looking for is what they call “historical contingency,” which means a succession of small, almost inconsequential changes that accumulate to create significant changes.

So how has the E. coli changed after the 70,000 generations in this evolution experiment? The latest generation of E. coli can reproduce 70% faster than their ancestors. They are still bacteria. In fact, they are still E. coli bacteria. They have not mutated into some more advanced form of life. Dr. Lenski wants to see funding made available to continue the experiment for another 30 or even 300 years in the hope of seeing more dramatic results.

The LTEE has inspired other scientists to conduct evolution experiments. There is one at Harvard experimenting with yeast. Other scientists have experimented with fruit flies (Drosophila) to study the evolution of multi-cell creatures. They have bombarded the fruit flies with radiation and chemicals, changing light levels, and changing temperatures. After thousands of generations, the result has been mutant fruit flies with extra eyes or wings that didn’t function. They were still fruit flies.

The bottom line is that multi-generation evolution experiments have not resulted in new creatures or even greatly improved old creatures. The changes resulting from mutations and natural selection are either harmful or insignificant. God created animals to adapt and change due to environmental forces. Humans can change and sometimes improve animals by selective breeding. We see that very clearly in the many and very different breeds of dogs. But the evidence seems to indicate that only God can make a Canine or a Drosophila or an Escherichia—or a human.

Design of Water and Miracle of Living Water

Design of Water and Miracle of Living Water

Have you ever been thirsty? I mean, REALLY thirsty!! Thirsty to the point of being willing to give anything for a drink of water? Water is precious. We are seeing the results of a lack of water in many places in the world today. There are entire cities where water is in such short supply that people have to go to extremes to get enough to stay alive. Because the design of water makes it essential for life, scientists looking for evidence of life on other planets start by searching for signs of water. The design of water makes it an excellent illustration of the miracle of living water.

We have discussed water’s chemistry before. The atomic structure of oxygen and hydrogen produces the polar nature of the water molecule, which gives water its incredible properties. The design of water is an amazing example of God’s engineering skills at all levels of complexity.

In ancient times having water was just as critical as it is today. Those of us who live in areas with abundant water have no idea how much the search for it dominated people’s lives in Jesus’ day. It is hard for us to fully appreciate the meaning of the teaching of Jesus in John 4 when He met the woman at the well and offered her the miracle of living water. The person who was assigned the task of keeping the family supplied with water had to be strong enough to walk long distances and carry heavy loads. This woman was going to carry something back to her family that was even more precious than the water she came to get.

“Jesus answered, ‘Everyone who drinks this water will be thirsty again, but whosoever drinks the water I give them will never thirst. Indeed, the water I give them will become in them a spring of water welling up to eternal life.’” John 4:13-14.

To the secular world, that statement is ludicrous, and yet Jesus refers to “rivers of living water” many times. In John 7:38, for example, Jesus says, “Whosoever believes in me… out of his heart will flow rivers of living water.” The next few verses explain, “He said this about the Spirit whom those who believed in Him were about to receive.” Because of our thirst, we understand the importance of water. For unbelievers, the miracle of living water is hard to comprehend, until they have a thirst for a better existence. In Acts 2:38, Peter told the people who WERE convinced that they needed a better existence that they would receive the gift of the Holy Spirit.

The design of water not only gives us life, but it helps us to understand the importance of the miracle of living water that Jesus offers. When you water a seed, it grows and begins a new existence. When you obey His commands and become a Christian, you begin a new and eternal life. That life brings peace and love, even to the most downcast and sinful person. Living water from Jesus is truly a miracle.

Forcing a Women’s Shelter to Accept Men

Forcing a Women's Shelter to Accept Men

The consequences of our culture refusing to accept God’s teaching and His creating of male and female continues to produce bizarre results. We are not talking about equal rights for equal pay, but of human compassion and care. We are talking about forcing a women’s shelter to accept men.

The Hope Center in downtown Anchorage, Alaska, is a faith-based women’s shelter that provides hot meals, job training, and beds for homeless women. Most of them have escaped from sex trafficking and abuse. When the Center refused to admit an intoxicated man in a pink nightgown, the city of Anchorage charged them with gender discrimination. Like similar laws in other cities, Anchorage has a law banning discrimination based on gender identity.

The Genesis account makes it clear that “God created man in His own image, in the image of God created He him; male and female created He them” (Genesis 1:27). For a variety of causes ranging from abuse to chemical issues, some people struggle with their sexual identity. These folks need our care, compassion, and support. Attempting to create a sexless society where there are no distinctions between male and female is a sure way to create chaos. Men can’t have babies, and some women are not equipped to handle certain roles due to physical size and strength. That is not discrimination; it’s just a fact. Sometimes there are needs peculiar to gender, and certainly, a women’s shelter meets some of those needs.

Imagine the problems that will develop if women’s shelters have to admit any man who says he thinks he is a woman. The Bible clearly tells us that humans have roles, both in the secular world and in the Church. In the Anchorage case, a lawsuit was filed in federal court, which resulted in a temporary order preventing the city from forcing a women’s shelter to accept men. In October, Anchorage agreed to make that order permanent.

Humans and Music

I went with my grandson to a musical instrument mega-store, where he was looking for an amplifier for his bass guitar. In addition to being a guitarist, he is also a drummer. While there, my ears were accosted as he tested a drum set and then tried out several bass guitar amps. The bass was so loud it rattled objects in the vicinity, and I could feel it pounding on my body. The experience reminded me of the connections between humans and music of all kinds.

My grandson purchased nothing because he didn’t find anything he liked in his price range. As we left the store, I was a bit relieved since my ears were still ringing. Stepping out into the parking lot, the sound of heavy traffic on the busy New Jersey street was relatively quiet.

Humans and music have been connected from the beginning. The artifacts left behind by the earliest humans include primitive musical instruments. Music styles change, and tastes in music vary from person to person. Just think of all the different musical genres and styles that people create and enjoy from country to classical, from jazz to gospel.

Music can stir our emotions. It can transport us to new places in our minds or stimulate us to action. Music can soothe our troubled souls, or a sad song can make us cry. The words of Christian songs can inspire us, and music can also tempt us into sin. Music goes beyond our minds and reaches into our emotions. What is it about music that so moves us? Perhaps it’s a desire for heaven.

Read the book of Revelation, and you will get an idea of the role of music in heaven. Music and worship go together, both in this life and in the life ahead. One of the things that distinguishes humans is our ability to create, perform, and appreciate music. Since we are created in the image of God, that must mean that God appreciates music also. Revelation indicates that singing for God before His throne will be a joyful experience. Until then, humans and music will go together as we long for the time when we are at home with God. For now, singing as we worship Him in our assemblies brings us joy as we honor our Creator.

Sex Selective Abortion

Sex Selective Abortion

The abortion issue is not only a political football, but now it has become a threat to population stability. That is because of sex selective abortions.

In India, 50,000 babies are aborted each month because they are girls, and females are considered to be a burden on the family. One long-term effect of the 17.3 million baby girls killed in India during the past 30 years is a huge gender imbalance in the population. In any human society, there is roughly a 50/50 balance between males and females. That means that if baby girls are aborted, there will be many males without wives, and that disrupts marriage, families, and children.

You don’t have to go to India to see cases of sex selective abortion. In 2016 the state of Indiana passed a law protecting the unborn from abortions based on race, sex, or disability. Planned Parenthood went to court to have the law overturned, and the court ruled that the law is unconstitutional. Earlier this year, the U.S. Supreme Court declined to address the case. We have been told that there are counselors who are advising expectant mothers to have an abortion because their baby is a girl.

U.S. Supreme Court Justice Clarence Thomas made this comment about the case:
“Enshrining the constitutional right to an abortion based solely on the race, sex, or disability of an unborn child, as Planned Parenthood advocates, would constitutionalize the views of the 20th Century eugenics movement.”

We would add to that comment that sex selective abortion shows even more clearly that abortion is infanticide. If you wait until you can determine the sex of the pre-born child, you are simply murdering an infant. We consider Herod’s killing of the innocents described in Matthew 2:16 as barbaric. In our world today, the slaughter far exceeds what Herod did.

Wood – Natural Multipurpose Building Material

Wood – Natural Multipurpose Building Material

We have mentioned before that many human inventions are actually adaptations of things we see in nature. That applies to products from Velcro to high-strength materials to airplanes. However, there are times when we can’t improve on the natural product, so we use it as God created it. An example of that is wood. It’s a natural multipurpose building material. Wood is strong, durable, flexible, weather-resistant, lightweight, and non-toxic. Lumber from trees is the most common building material for homes and other housing structures.

How could there be such a well-designed and valuable natural multipurpose building material? Wood is produced in a living plant. Under the protective bark of a tree lies the cambium layer. It is the innermost layer of the bark where growth takes place. Each year, during the warm months, the cambium produces living cells, which become the new sheath expanding the trunk of the tree. The layers from previous years remain as the wooden skeleton giving strength to the tree. If you cut it down, you can count those layers as visible rings revealing the age of the tree.

The tree’s roots take in water with vital nutrients from the ground. Within the woody trunk, there are microscopic conduits called xylem carrying that water up to the leaves. Just outside of the cambium, another layer of micro-ducts called phloem moves sugar-water that the leaves produce using the amazingly complex system of photosynthesis. The phloem supplies nourishment that the cambium requires to build the new sheath of wood. When the growing season ends, the phloem carries the remaining nourishment to the roots for winter storage until next spring.

Trees often lose branches from wind, ice storms, other natural means, or by human intervention. When that happens, it can throw the tree off balance. The cambium steps in to build a thicker sheath on the side where the limb was lost, reinforcing the tree to bear the uneven load. When examining the rings of a felled tree, a ring that is thicker on one side indicates a fallen branch. The tree automatically takes care of the area of the lost limb by covering it with new annual sheaths.

Take a moment to look at the wood in your house. That natural multipurpose building material in the window and door trim, the floor, and your furniture was once alive. It was growing and transporting sap while the leaves converted sunlight and water into sugar-water to nourish the tree, and the cambium created new growth. The lines in that wood tell the story of days and years of rainfall, sunshine, wind, and changing temperatures in a forest somewhere in the world. The wood in your house is not there by accident, and we don’t believe the tree was a natural accident, but the work of a creative Engineer.

Trees Prepare for Winter

Trees Prepare for Winter

Imagine standing naked outside on a cold winter day. When winter’s chill comes, people take shelter. If we have to be out, we put on more clothing. Most animals have fur or feathers to help keep them warm, and they also seek shelter from the cold. Trees in winter can only stand there and take it for months at a time. So how do trees prepare for winter?

Living cells in plants or animals consist primarily of water inside a membrane. If you leave a bottle of water in your car on a night when the temperature drops below freezing, you know it will freeze and break the bottle. That is because water has the unique property of expanding as it freezes. The same thing can happen in living cells. If the water in the cell freezes, it will expand and rupture the membrane. Animals that are endothermic (warm-blooded) generate heat within their cells by burning sugar to produce energy. Plants make sugar using light energy. With a few exceptions, they don’t produce heat.

How do trees prepare for winter? They use a process botanists refer to as “hardening.” The cell walls become more permeable to allow water to escape. At the same time, sugars, proteins, and acids in the cell are concentrated into a syrupy liquid, which acts as an antifreeze. The spaces between the cell walls become filled with ultra-pure water filtered through the cell walls. Pure water without stray atoms to form a nucleus around which ice crystals can grow, will freeze only at a much lower temperature. With the cells filled with antifreeze and spaces between having only ultra-pure water that can be super-cooled without freezing, the tree is ready for what the winter brings.

How does the tree know that it’s time to harden for winter? Fall weather can fluctuate quickly and dramatically. A tree can’t depend on the fickle weather because it could easily be fooled by warm days that suddenly turn cold, causing it to freeze to death. Trees know when to prepare for winter because of the length of the days – the “photoperiod.” Weather is unpredictable. The Sun is absolutely dependable. When the tree senses a decrease in light in each 24-hour cycle, it knows winter is coming, even if the weather is unusually warm. The pattern of changing daylight and darkness is exactly the same every year, even though the weather is capricious.

God engineered this incredibly well-designed system. “Then God said, ‘Let there be lights in the expanse of the sky to separate the day from the night. They will serve as signs for seasons and for days and for years’” (Genesis 1:14). Thus God designed the system which says, “Trees prepare for winter.” It’s another engineering marvel from the Creator.
