Scopes Monkey Trial Nonsense Continues

Scopes Monkey Trial
In July of 1925, a silly trial took place in Dayton, Tennessee. A school teacher named John Thomas Scopes had broken Tennessee law by teaching evolution. People call it the Scopes monkey trial.

On the prosecution side was William Jennings Bryan, the spokesman for fundamentalist advocates of the Bible. (Bryan is sitting on the left side of the picture.) Clarence Darrow was the humanist opponent arguing for the defense. (You can see him standing on the right questioning Bryan. The judge had moved the trial outside because of the heat in the packed courtroom.) At the time, people called it “the trial of the century.” After eight days of the trial, it took the jury nine minutes to convict Scopes, and the judge fined him $100.

The problem was that no one bothered to define “evolution.” Nobody took the time to see what the Bible really said. The weaknesses of denominational teaching were attacked, not the evidence or understanding of what science and the Bible actually say on the subject. Both sides claimed a win, but in reality, neither side won. Books, theatrical productions, and movies have perpetuated the story, and it has given great promotional value to the little town of Dayton.

The latest example of how this battle goes on appeared on July of 2017 when a statue of Clarence Darrow was dedicated on the Dayton courthouse lawn. The dedication drew an organized protest by fundamentalists who already have a statue of William Jennings Bryan in the area. The newspapers billed it as a “religion versus science” debate. A recent Gallup poll shows that the number of Americans who believe that evolution is the only possible answer to the origin of all living things has grown from 9% in the late 1980s to 19% today.

Science and faith are friends and not enemies. That has to be true because the same God who created the universe and life gave us the account of what He did. If there is a conflict, we either have bad science or bad theology. The lesson of history and the Scopes monkey trial is that we have had a lot of both.

Different Shades of Brown

Different Shades of Brown
Racial prejudice based on skin color is a function of ignorance. I am amazed that promoters of violence against black-skinned people have daughters who are using tanning booths to get darker. There is no inferior race, and there are no different species of humans. Acts 17:26 tells us that God “has made of one blood all nations of men for to dwell on all the face of the earth…” We are all just different shades of brown.

Many years ago the preacher of the Central Church of Christ in Birmingham, Alabama, invited me to participate in a television panel discussion. The format was a call-in where callers could ask questions for the panel to answer. On the panel with me was the black president of a small African-American college in East Texas.

The discussion took place during the time of racial strife in Birmingham. A caller asked if black people were evolved apes and white people were created by God in His image. I responded by pointing out that apes and white people have more features in common than apes and black people. This includes hair texture, jaw shape, skull shape, and even skin color when you look under the hair. This produced some antagonism from our host but was followed by the question of why black people are black and white people are white.

I took my hand and laid it on a white sheet of paper and asked if I was really white? The answer, of course, was that I wasn’t white like the paper. I was light brown. Then I asked my black friend to lay his hand on the same sheet of paper, and I asked if he was really black? The answer was obvious. He was just a darker shade of brown. I then made the point that we are all just different shades of brown, and we are all equally created in God’s image.

My black friend leaned over and whispered in my ear as we looked into some rather hostile people at the TV station. He said, “Ain’t neither one of us getting out of here alive.” I am glad to say that we did.

Neanderthal Genes

Neanderthal Genes
There has been a lot of confusion about the Neanderthals in both religious publications and scientific writings. Scientists have reported that there are Neanderthal genes in modern humans.
Many have treated the Neanderthals as ape-men, and there have been multiple theories about how they originated.

Religious publications have speculated about Neanderthal influence on biblical characters. Those who wish to find “giants” in biblical accounts have claimed that the Neanderthals were giants, and at least one set of fake pictures of huge skulls has circulated on the internet attempting to back that up.

Researchers in Germany have just reported on DNA studies of the Neanderthal genes in modern humans. They found 15 Neanderthal DNA traits in modern humans. What is interesting is that these 15 traits show up in people of British ancestry, but people of pure African descent have no Neanderthal DNA. This will certainly complicate some of the “out of Africa” theories about the origin of humans.

We suggest that most of the claims of prehistoric humans involve racial variations. No claim of different species of humans is supported by the evidence. The biblical claim that Eve is the mother of all humans (Genesis 3:20) continues to be strongly supported as we study our past.

Origin of Life Complexity

Origin of Life Complexity
The origin of life complexity continues to baffle science. There are two competing scientific theories on the origin of life. One is called the “Darwin school of thought” which posits that meteorites brought elements to Earth that led to the formation of compounds which led to RNA and then to DNA. The second theory says that life originated in mineral-rich hydrothermal vents on the ocean floor.

The problem with both of these theories is that they are not explaining the origin of life complexity. They are only explaining some of the compounds that would be necessary to form life. Many scientists question the possibility of either of these theories and whether organic compounds could survive in the conditions of the early Earth. The bigger issue is how you could move from those compounds–no matter how they were formed–to a living cell.

You not only must have the ingredients to make life, but you also need a protected environment in which those compounds can be combined. Life could not begin in a toxic atmosphere or if there were agents on Earth’s surface that would destroy the ingredients. RNA and DNA involve long strands of nucleotides. Scientists in the laboratory can only produce such chains in a carefully controlled environment. The time element involved in producing increasingly complex molecules is also an issue.

When we enter probabilities into this process, the odds of each step happening by chance are very unlikely. Then to put all the steps together in the right order makes the probability of it happening by chance outside the scientific limits of what is possible.

Research into the origin of life complexity strongly points to an intelligent Creator. The more we learn, the more complexity we see. The famous atheist Antony Flew saw the complexity of a living cell, and that was a major factor in his coming to believe in God. His statement of faith was, “You have to go where the evidence leads.” Certainly, this area of study gives evidence of God’s wisdom and creative design.

Skeptic Challenges

Skeptic ChallengesDOES GOD EXIST? maintains a Facebook page with daily postings. We often get skeptic challenges and questions from those who are seeking for answers. We want to share the following conversation from Facebook:

SKEPTIC: Maybe instead of “Does God Exist?” you should call your page “straw man arguments that I just made up and took no time to research.” Proteins collected, microorganisms slowly developed, they grew, became more developed, and developed very slowly into animals we recognize today. It really isn’t something you can’t Google whenever. But if you think everything is designed by your interpretation of the Jewish/Christian god, what designed him? Does the designer of the designer have a designer? Does it just go on forever in a ridiculous infinite cycle?

DGE?: You are on very shaky ground with that narrative of life coming together from non-life. But the real mistake you are making is thinking that God had a beginning. God created time and space, matter and energy at the moment often referred to as the “big bang.” Since God created time, he is not confined to the dimension of time. Since God is outside of time, he has no beginning. We are so confined to understanding things in the time dimension that it is difficult for us to grasp that concept. We think that everything has a beginning because that is true of the world we live in.

SKEPTIC: Isn’t it really easy to just say something exists outside of space and time and therefore doesn’t need to follow the laws of physics? What if I said that the creator of the universe is a giant, two-headed penguin? What if I were to say that the giant penguin exists outside of time and space (and that he wants you to give me money)? Would that be any less valid than what you’re asserting?

DGE?: Scientists say that space/time, as well as matter/energy, had their beginning at the singularity known as the big bang. Whatever created time (as well as space, matter, and energy) must exist outside of those dimensions. Some have tried to argue that the universe just happened without a cause. However, that is not a scientific statement because it cannot be tested. Sorry, it could not be a penguin because penguins (especially giant ones) have mass and therefore they are matter. As the Bible says, with scientific accuracy, “God is a spirit.”

SKEPTIC: To say that the universe having no cause is unscientific, while claiming the existence of some god living outside of physics, is hypocritical to say the least. If it’s necessary for everything to have a cause, what caused your god? If the universe HAS to have a cause, why not carry that same logic to the god you’re claiming?

DGE?: You are right that claiming the existence of God as the creator of space/time and matter/energy is not a scientific statement. The reason being that it cannot be scientifically tested. All we can know scientifically is that at the moment of creation space/time and matter/energy came into existence. That means that whatever caused those things to come into existence has to be outside of the space/time dimension and cannot be made of matter/energy.

We also know that since the cause is outside of space/time, it cannot be limited by space/time. That means it had no beginning in time, so it had no cause. It always existed. Those things can be proven logically and scientifically. From there we have to rely on faith since this is outside of the realm of science. I choose to believe that the creation was by an intelligent God. You may choose to believe that the creation was by and out of NOTHING. (Which is what some otherwise intelligent scientists have suggested.) Whether you choose the intelligent God hypothesis or the Nothing hypothesis you are acting on faith. I think that God is a more rational explanation.

SKEPTIC: It isn’t rational to believe things on faith. I’m not claiming “nothing” created the universe. I’m saying we don’t know, so we shouldn’t fool ourselves. You can’t claim to be reasonable if you 1) claim it is reasonable to say “we both don’t know, so I guess I’m right” 2) think something existing outside of time and space is plausible, but bacteria slowly forming from proteins in water is crazy talk.

DGE?: Okay, you are not saying that Nothing created the universe. However, I am sure you understand that the universe was created FROM nothing. I am sure that you understand that whatever did create the universe created time/space and matter/energy and therefore cannot be limited by or be made of those things. So the question is whether the thing which created time/space and matter/energy was Something or Nothing. Something seems more reasonable to me.

SKEPTIC: There’s no proof that “something” exists outside of the universe. It is, by definition, impossible for something to exist outside of reality. If it exists outside of reality, it doesn’t exist. It isn’t real. It’s imaginary. You’re providing logical proofs that not even a 4-year-old would buy. You first say that you have a specific something. You then say that this something must exist, solely on the grounds that we have stuff and not no stuff. When challenged on it, you say that it must exist, because what else would create the universe? Okay. What created your something? Another something? What created that something? Oh, it exists outside of time and space? And you have no evidence? Great. Just wonderful. You’ve won me over.

DGE?: How do you define this “reality” that you refer to? You have brought that word into our conversation, and you seem to be defining it as that which we can detect with our senses. Do you believe that nothing is “real” unless we can see, hear, touch, taste, or smell it?

SKEPTIC: If you cannot detect something in any way, it isn’t real. This isn’t exactly hard to understand. But you’re dodging around the fact that something cannot exist outside of reality, let alone create it. When you provide evidence that your particular interpretation of a particular deity is real, you may have some ground to stand on.

DGE?: You seem to have difficulty understanding that many (or should I say most) scientists believe that time began at the big bang. If that is the case, then whatever caused the bang has to exist outside of time. (Also it has to exist outside of space, since time and space are inter-related, and space began at the big bang also.) Either you have to say that Nothing created everything we see, or you have to say that Something outside of time created everything.

The only other idea posited is that the universe is cyclical and the big bang came from a previous universe that had compressed itself into a tiny point that exploded into a new universe. This theory has been rejected by scientists because nobody today believes that the universe will start to compress into a point and explode again. The expansion rate of the universe is increasing, not slowing down, and the energy will eventually dissipate. Also, the cyclical idea still doesn’t explain where it all began.

All we have left then are two possibilities. Either Nothing created the universe or Something outside of time and space created time and space and matter and energy and everything we see. Some scientists (Stephen Hawking and Lawrence Krauss) have suggested that the universe came from Nothing because Nothing is unstable and therefore it morphs into a more stable state. I don’t see how that can be called a scientific theory unless it can be tested. I also think it takes more faith to believe that life (including human intelligence and creativity) came from Nothing than to believe that these things came from an intelligent Designer.

SKEPTIC: Again, I’m NOT SAYING “NOTHING” CREATED THE UNIVERSE! We don’t know what created the universe, or if the universe always existed somehow, but to say that you’re right because you can’t imagine “nothing” creating the universe is fundamentally flawed. If you think something created the universe, demonstrate what it is, then demonstrate that it exists, then demonstrate that it is your god (I’m guessing you’re a Christian, I apologize if I’m wrong). But if you cannot demonstrate that your god made the universe, or even that he exists, you should not expect anyone to believe you. But again, just because you think “something” made the universe, that doesn’t mean that it should be exempt from the laws of physics. Show your proof.

DGE?:
You say we don’t know “if the universe always existed somehow.” You would have a hard time finding any reputable scientist today who would say that the universe always existed. Discovery of the microwave background radiation from the cosmic creation event put the final nail in the coffin of that idea. So, since the universe had a beginning, the only choices seem to be that it had a cause, or it did not have a cause. It either created itself out of Nothing, or it was created by Something. That Something has to be outside of time and space, or it could not have created time and space. You can call it God or you can just call it Something. Science cannot go back beyond the big bang, so there is no scientific way to prove what that Something is.

SKEPTIC:
There’s no way to prove there is anything outside of reality, but again, by definition, NOTHING CAN EXIST OUTSIDE OF REALITY. It isn’t plausible. You’re using circular logic.

DGE?: You are saying that reality is only the 4-dimensional world that you know and that nothing can exist outside of those four dimensions because that is all you know. And you are accusing me of using circular logic.

SKEPTIC: Who brought up four dimensions? Are you trying to use pseudoscientific terms to try to sound smart?

DGE?: In case you didn’t realize it, the four dimensions we live in are width, height, depth, and time. (Or X, Y, Z, and T, if you prefer.)

SKEPTIC: Riiiiight… Well, you literally can’t have something existing outside of reality. You think I’m wrong? Show me your god.

DGE?: You are avoiding the issue. You continue to use “reality” as things you think are real and anything you don’t think is real is outside of “reality.” Your reality is too small. As you know, it is not possible to prove scientifically that God exists, and it is not possible to prove scientifically that God does not exist. Nobody has ever seen the so-called “dark matter,” but scientists believe it exists because they see its effect on the galaxies. Nobody has ever seen an electron, but we believe electrons exist because without them our computers would not work, and we would not be carrying on this conversation.

Likewise, even though we cannot see God, we see the universe around us. We know that the universe had a beginning and there had to be a cause of the beginning. You can choose to believe that there was an intelligent Creator or you can believe that it just happened out of nothing and by Nothing. You can also believe that electrons and dark matter don’t exist. Your computer works by magic, and the galaxies are held together by imagination. Each person decides what to believe, and I suggest that you keep an open mind.

SKEPTIC: As common sense and centuries of logical thought have proven, you should not believe in things that cannot be detected. I cannot detect magical leprechauns in my garden, but what else would cause my plants to exist? Well, I must be right, right? That’s proof enough for you, right? Look, I know you know I’m winning. That’s why you’re making it personal by accusing me of being closed-minded, which is highly inappropriate. Shame on you. You’ve lost. No one who is winning an argument will attack the other person. If you want an intelligent discussion, then that’s wonderful. I encourage it. But if you think it’s okay to say someone’s closed minded when they disagree with the same tired argument, then shame on you. I have no time for people who can’t maintain their arguments on their points’ own merits and resort to accusations of closed-mindedness.

DGE?: You say you won and I lost. I didn’t know this was a contest with a winner or looser. I thought it was an intelligent discussion about important things. In fact, I would say eternally important. You say that one should not believe in things that can’t be detected. Then I would expect that you would take issue with the many scientists who believe in dark matter which they have not been able to detect. Look it up on Wikipedia. They believe it exists because it explains things that they cannot explain otherwise.

I also suggest that you look up a book written by Edwin Abbot in 1884 titled “Flatland: A Romance of Many Dimensions.” It’s available on Amazon for only a few dollars, and the Kindle edition is free. It is pretty much required reading for students of math, physics, or engineering. It’s a satirical novel about a man who lives in a two-dimensional world called Flatland. He is unable to believe that there could be a third dimension when a sphere shows up in Flatland and challenges his thinking. You don’t seem to be open to anything that challenges your way of thinking.

It has been interesting discussing these matters with you. I wish you well. I would say, “God bless you,” but that would probably offend you. So I will just say, “May the Force be with you.”

Artificial Life Synthetic Biology

Artificial Life

I just ran across an Associated Press news article in my files. The headline reads, “Scientists Believe Artificial Life Will Be Possible in 3 to 10 Years.” The article is dated August 20, 2007.

The report deals with a new scientific discipline known as synthetic biology. The goal is to create life in the laboratory. Two of the pioneers in this field are Jack Szostak and Craig Venter. Szostak’s team has taken the bottom-up approach to build artificial life-forms. They seek to assemble the biomolecular building blocks step-by-step until they have a living cell. Venter’s team takes the top-down approach. They try to re-engineer existing life-forms by changing the DNA to create novel forms of life. Both teams have made progress over the last ten years, but neither has achieved the ultimate goal.

The AP article says there are three major hurdles to creating artificial life. First, you need a container or cell membrane. It serves as a protective wall to keep the materials required for life inside while keeping the harmful molecules out. Living cells must have that. Secondly, you need a genetic system that controls all of the cell functions. This system has to allow the cell to mutate in response to the environment and, very importantly, to reproduce. The third essential is a system of metabolism. The cell must be able to take raw materials from the environment and convert them into energy to power the cell.

Those three hurdles are still challenging the scientists. In time, scientists may jump the barriers and create fully-synthetic artificial life. In doing so, what will they have proven? Will they have shown that life arises spontaneously from non-life? No. They will have proven that great intelligence under carefully controlled conditions can turn non-living matter into life-forms. They will have shown that life is not an accident, but the creation of an intelligent being. That is what the Bible has said for thousands of years.

Even when those scientists manage to create a living cell, they will NOT have created it from nothing. They will be using the materials (and intelligence) that God has given us. It reminds me of the old story about a scientist who challenged God, saying that is was no big deal to create a man from the dust of the ground. God said, “Go ahead and do it.” The scientist grabbed up a handful of dust, and God interrupted him, saying, “Wait a minute! Make your own dust.”

Turkish Government Will Remove Evolution

Turkish Government Will Remove Evolution
Turkish education minister Ismet Yilmaz has announced changes to the textbooks in that country. Starting next fall, the Turkish government will remove evolution and all references to Charles Darwin from the textbooks along with 170 other topics that do not coincide with the Islamic government views. The new curriculum to replace these topics is said to be “value-based” and in harmony with student development.

The current biology course for twelveth grade biology has a section titled “The Beginning of Life and Evolution.” It is being replaced with a unit titled “Living Beings and the Environment.” This new course will include discussions of adaptation, mutation, and natural and artificial selection without mentioning evolution or Darwin. An earlier section for an eleventh-grade philosophy class will be titled “Evolution and other Ontological Opinions.”

The situation is complicated in Turkey not only because of the influence of Islam but also because of the failed coup in 2016. The government is using the schools as a way to control the population. Included in the new curriculum are units about the groups that the government is fighting such as the Kurdistan Worker’s Party and the U.S.-based Muslim cleric Fethullah Gulen.

American creationist groups that want to include their particular view of biology in education may want to look at what is happening in Turkey. The new curriculum, which is religiously based, is turning the classroom into a political football. It will be interesting to see if the Turkish government will remove evolution from the educational system without causing major civil unrest.

We have pointed out that modern agriculture, animal husbandry, aquaculture, and fish management depend upon the basic concepts that Darwin presented. The fact that animals can change and that this change can be used to benefit the world is important for young people to learn. The enemy is naturalism in which these concepts are expanded to exclude God’s role.

It’s Good to be Blue

It's Good to Be Blue Begonia Leaf
It’s a plant that uses quantum mechanics to make maximum use of minimum light, and in doing so, it displays blue leaves. The explanation of why blue begonias are blue is another demonstration of the incredible design built into all living things.

The tropical begonia (Begonia pavonina) that grows in Malaysia has leaves that are iridescent blue. The blue does not come from pigmentation, but rather from structural color, a technique that gives beautiful color to some birds, Butterflies, and beetles. In the leaves of all kinds of plants there are cellular capsules called chloroplasts, and inside those structures is a green substance known as chlorophyll. The chloroplasts are the organic machines that take energy from sunlight and chemicals from the soil to make organic energy that allows the plant grow.

Sunlight is a mixture of light at various energy levels, but green is the highest energy of sunlight reaching the surface of the Earth. Since the chlorophyll pigment reflects green light, the plant is protected from being damaged by the high-energy sunlight. We see the reflected green light, so the leaves look green.

Blue begonias live on the floor of dense rain forests where the forest canopy restricts the light. Inside the chloroplasts of these begonias, there are nano-structures called thylakoids where the energy conversion takes place. Other plants have thylakoids, but they are arranged differently in the begonia. Scientists using an electron microscope discovered that the thylakoids are aligned in a way that they act like crystals. In other plants, they are haphazard in their arrangement. Light bounces around within the thylakoids causing interference at certain wavelengths and reflecting the iridescent blue. The light is slowed down in this process so the plant can use more of the high-energy green and red light while reflecting the blue. These plants are using principles of quantum mechanics which scientists only began to learn about in the twentieth century.

The result is that the blue begonias get the nutrition they need to survive in a location with little sunlight, and we see the leaves as a beautiful blue. One science website described the alignment of the thylakoids in this way: “…they have an amazingly regular structure, which is obviously planned.” Here is the way another science website described the unique way these begonias efficiently use the limited sunshine they receive: “It seems selective evolution led the plants to engineer a nanoscale light-trapping structure, the likes we’ve only seen in miniature lasers and other photonic structures made by humans…”

We believe that planning requires a planner and engineering requires an engineer. As scientists study even the simplest forms of life, they find more and more evidence that God is ingenious in all He creates.

Apes and Humans

Apes and Humans
Is there an evolutionary connection between apes and humans? Many years ago in a youth rally, a young lady asked me, “If we didn’t come from apes, how come my brother looks so much like an ape?”

It is true that we share many physical characteristics with the apes. Apes and humans both have stereoscopic vision, necessary for depth perception. We both have opposable thumbs, necessary to hold a tool or a club. Apes and humans have noses immediately above our mouth to detect and analyze flavor. Naturalists who want to explain everything on a chance basis suggest that apes and humans share a common ancestor.

Those naturalists frequently ignore the fact that there are many things humans do not share with apes. These are not physical characteristics, but they are what separate us from all other forms of animal life. They include our capacity for worship and our ability to create music and art. Only humans have the ability to think and reason in abstract terms. Apes do not share our capacity for guilt and sympathy, including our ability to have an “agape” kind of love that isn’t survival based.

We would think that with our genome being so similar to the apes some of these characteristics should show up to some degree in the apes. In spite of attempts to show such connections, it is increasingly obvious that such attempts are complex exercises in anthropomorphism.

The question then is, “Why do we see such an enormous collection of fossils of primates which is expanded daily by paleoanthropologists?” In The September 2, 2017, issue of Science News Bruce Bower reviewed some of the evidence and current theories about ape evolution.

The bottom line is that there are connections between specimens like oreopithecus, modern day gibbons and recent finds like Nyanzapithecus alesi. The capacity of life-forms to change is a fact that no one can deny. The various races of human beings indicate that humans have changed enormously since the beginning. The Bible tells us about our human spiritual nature, and that nature has not changed throughout our history. Our physical makeup has changed a great deal during that time, and apes have changed even more.

We see humans as a special creation of God–created in His image with characteristics that are not a product of physical changes. As scientists find more fossils of apes, they will study the changes that have taken place leading to the wide variety of monkeys and apes in the world today. They will create more theories about the physical evolution of apes. In spite of that, the special place of humans in relationship to God will remain unchanged. How we should treat other humans with love and compassion will also not change.

Nursing Orangutans and Evolution

Nursing Orangutans
As scientists study different animals in their natural environment, they frequently learn things that complicate accepted pictures of animal history. A recent series of studies of nursing orangutans in Borneo and Sumatra has shown that weaning doesn’t occur in these animals until they are more than eight years old. That is a record lactation period for any wild animal.

Determining the length of nursing for orangutans has been difficult for various reasons. For one thing, the nursing takes place high in the trees, so scientists have difficulty observing. Add to that the fact that these animals are hairy, so it becomes difficult to see what is going on. Some have suggested that the babies are just cuddling.

Researchers finally settled the question by studying orangutan teeth. Studies of the layers of material containing barium in the teeth of the babies indicate that they really are feeding. Museums have collections of orangutan teeth from years ago when these animals were not considered to be endangered and were often killed by collectors. Calcium and barium from the mother’s body go into building the nursing infant’s teeth. Primate teeth are built up with a microscopic layer each day. By examining the layers, scientists can tell when the infant orangutan stopped nursing because there is a greater concentration of barium in the nursing layers. Examining teeth from orangutans at different ages, the scientists determined that nursing can continue through age eight.

Some evolutionary theories have difficulty with these very long lactating periods. Not only is the female not receptive to males during that eight years, but she must continue to produce milk. In milk production, the mother is literally dissolving some of her body to provide nourishment for the young. These two factors seem to be counter to evolutionary models for survival. These new discoveries concerning nursing orangutans may cause some rethinking concerning theories of primate evolution.
