Dawkins-Remolina Debates in Colombia

Dawkins-Remolina Debates in Colombia
If you have followed this ministry for a while, you will recall that in the summer of 2017 John Clayton spent several weeks in Colombia giving many presentations on evidence for the existence of God. He was invited to speak there preceding debates between atheist Richard Dawkins and Catholic priest Gerardo Remolina. Remolina is a leading scholar at the Jesuit Pontifical Xavierian University in Bogota, where the first debate took place. We received a newspaper account of the first debate, and we hope to eventually have a chance to review reports of the Dawkins-Remolina debates at Medellin and Cartagena.

It was interesting that in the first debate there was almost nothing said about the existence of God. Remolina suggested that the age of the universe was 14 billion years and that the age of the Earth was around 5 billion years. Dawkins said he agreed but stated that 40% of the American public thinks the Earth is less than 10,000 years old. Dawkins said that is equivalent to believing that the North American continent is only 8 meters wide. Dawkins continued to maintain that belief in God is due to ignorance on the part of believers, and Remolina made no response to Dawkins claims.

Dawkins stated the atheist belief that life evolved mechanically and that the Bible was a collection of diverse myths. Remolina agreed that Adam and Eve are a myth but said that the myth is a structure of thought and does not pretend to explain anything. Dawkins claimed that the Bible was not historical because there is no evidence of the events it describes. Remolina could have given massive evidence for the historical validity of the Bible, but instead, he stated that science uses myths. He quoted Carl Sagan’s statement that the “Big Bang” was a myth because science cannot duplicate it in the laboratory. Dawkins attacked the Catholic tradition of original sin ridiculing the teaching that children are born sinful.

We are reading a translated newspaper report which may be incomplete. The fact is, however, that the debate was about Catholic traditions and opinions of Dawkins on the history of life. The fundamental arguments for the existence of God–cosmological arguments, teleological arguments, moral arguments, ontological arguments, and philosophical arguments–were barely mentioned and evidence was not presented by either side. We hope that later Dawkins-Remolina debates will approach the real questions and the weight of the evidence29. Stay tuned.

Bird Migration Data

Bird Migration Data
A fascinating area of study is bird migration. With new technologies, scientists are gathering more bird migration data than ever before.

Arctic terns spend their summers in Alaska and migrate thousands of miles to wintering grounds in South America. Years ago researchers demonstrated that the tern didn’t get the migration information from its parents because terns raised in isolation having no contact with other terns could still make the journey. Terns deprived of visual acuity could still make the journey, so the migration was not by landmarks. The Earth’s magnetic field was not the method because terns equipped with a magnetic scrambler could still make the journey. Similar tests showed it was not by smell or by sound. The researchers concluded that the tern used several navigation tools. If one was lost, the bird would switch to another. We suggested that such a complex system was not a product of chance. It is designed into the tern’s DNA suggesting that God had something to do with the design.

In the March 2018 issue of National Geographic, there is an excellent article titled “Epic Migrations.” Scientists use new tools to collect bird migration data that enables a much more precise understanding of both short and long migrations. Nearly half of all bird species are migratory, so there are a large number of species to study, and scientists are gathering new data continuously.

The long-distance winner of migration is the bar-tailed godwit. One specimen flew 7,150 miles non-stop in eight days from its summering grounds in Alaska to its wintering grounds in New Zealand. In the weeks before migration, godwits build up enormous layers of fat adding more than half their body weight. When they arrive in New Zealand, they have lost all of the fat reserves. Because they do not glide or soar in the journey, their wings are beating all the time. On the way back to Alaska, the birds travel 6,000 miles to China near the Yellow Sea where they spend six weeks. Then they fly 4000 miles back to Alaska. Their departure time for these trips is the same from year to year, influenced only by local weather and winds. They seem to be guided by a precise clock.

Researchers have found an assortment of interesting bird migration data. Studies of frigatebirds in the Pacific show that they sleep while soaring, but only for about 12 seconds at a time for a total of 42 minutes a day. Research shows that half of the bird’s brain is asleep and the other half is awake. Other studies have shown that European starlings use the Sun as a compass and that indigo buntings use stars as a compass. European robins use an internal magnetic compass. When researchers artificially rotated the magnetic compasses by 90 degrees, the birds flew the wrong direction until the Sun came up. Then they reset their magnetic compasses using the Sun for orientation.

Each species of migratory birds seems to have their own built-in devices to make their journeys. The programming of their DNA is incredibly complex and seems to be a designed characteristic built into each species. We can learn a great deal about God by observing the world around us, and truly “we can know there is a God through the things He has made” (Romans 1:20).

Letters in the Sand

Letters in the Sand

What do you see in this picture? Look closely, and you will see evidence of letters in the sand.

Notice the waves that were caused by wind blowing across the desert. Then notice the astonishing thing the wind has done! The wind has created some lines in a fascinating pattern. The lines seem to spell out the name of the world’s largest hot desert—SAHARA. Yes, the Sahara Desert covers most of northern Africa, and to find something this amazing that the natural forces have “written” on the sand is truly unusual.

Wait a minute! Are you suggesting that those letters are not the effect of the wind and natural forces? Are you thinking that maybe an intelligent being actually wrote in the sand? Consider carefully the fact that the Sahara is enormous, and there are vast areas of sand. Given enough time and the proper wind directions, why couldn’t this word show up by natural forces alone? Surely somewhere in that desert, there must be a naturally formed letter—maybe an “S.” Surely in all of that area, it is possible that natural forces could have formed the other letters. Given the billions of grains of sand and enough time, they could just happen to line up in the proper order to spell a word. Couldn’t they?

Okay, you are not buying my story. Perhaps an intelligent being was involved in the formation of this word in the sand. But if you won’t believe me concerning the six letters in the sand, would you believe three-billion letters? That’s how many letters came together in the proper order to form the DNA strands in every cell of your body. That DNA code gives the complete blueprint for YOU. You can read S-A-H-A-R-A in seconds. If you were to read the three-billion letters of the DNA from one of your cells at the rate of one per second, every second of every hour of every day, it would take 31 years. Do you believe that the DNA code came into existence in a completely natural and unguided way?

Oh, you are suggesting that it all started with something simple and then evolved into what it is today. Sorry, but fossil evidence shows that even the simplest bacteria that emerged shortly after the Earth came into existence had extremely complex DNA codes. Life can’t exist without the code. The code is information, and information is the product of intelligence. We suggest that just like those letters in the sand, life can’t happen without an intelligent Creator.

God’s Natural Cloning

Natural Cloning of Crayfish
When scientists reach a new accomplishment, they sometimes discover that God has already done it. The marbled crayfish (Procambarus virginalis) has been reproducing by cloning for more than 20 years. Natural cloning, or parthenogenesis, is one of the tools of God for species reproduction.

Someone caught a female slough crayfish (Procambarus fallax) in the Florida Everglades in 1995. A hobbyist bought it for a pet. For an unknown reason, it became a new species called the marbled crayfish and started cloning itself. The hobbyist could not take care of the increasing numbers of crayfish, so he took them to a pet shop where others bought them for their aquariums. A German aquarium owner bought a bag of these mutant crayfish from an American pet trader and found his tank overrun with female crayfish. The marbled crayfish are all female clones from the one female crayfish. The number has gone from one to billions around the world today.

Crayfish are at the bottom of the food chain for freshwater ecosystems, and with this new method of reproduction, the supply of crayfish can be good even with heavy predation. These crayfish can adapt to so many kinds of environments that scientists are concerned about them becoming an invasive species in various areas. Researchers have recently sequenced the genome of the marbled crayfish to learn more about this creature. They are suggesting that study of marveled crayfish reproduction may give clues to how tumors develop and grow.

We still have a lot to learn about these cloned crayfish. There are other organisms in which natural cloning occurs without male participation. Study of this design feature may lead to more advances in the areas of food production and health.

Human Species and Racial Differences

Human Species and Racial Differences
One of the oldest controversies among anthropologists is over whether a “splitter” view or a “lumper” view is the most accurate description of human history. As scientists study ancient fossils, they have to determine whether they should be split into different species of hominids or lumped into races of one human species. One of the famous splitters was Louis Leakey who attached a new name to every find he made. Because of his long and productive life in studying the fossils of Africa his names have stayed around for a long time.

Other anthropologists have suggested that many of the specimens with unique names were actually just racial variations. Races can look very different and yet still be one species. There is just one human species. Looking at the skeletal remains of a Pygmy and a Swede, one might conclude that they are two different species, but they are fertile with one another, and they are one species. Racial characteristics are usually related to climate. Skin color is related to how close to or how far from the equator ones’ ancestors have lived. Lighter skin color can absorb more vitamin D from limited sunlight, and dark skin gives greater protection from the harmful rays of the Sun.

All of this has been getting attention recently as scientists study the DNA of the remains of various humans. The London Natural History Museum has just released a study of the DNA of the so-called “Cheddar Man”–a human skeleton discovered in Cheddar Gorge, Somerset, England, in 1903. The study suggests that this person had dark skin, blue eyes, and curly hair. The theory is that the British landmass was connected to continental Europe and that humans migrated into the area with some of them coming all the way from Africa.

The Bible makes it clear that there is one human species. The apostle Paul said in Acts 17:26 God “has made of one blood all nations of men to dwell on the face of the Earth.” What distinguishes humans as a species is that God created us in His image which gives us the ability to worship and have creativity and a concept of self. Our physical characteristics which identify us racially are simply functions of genetic heritage and the environment in which we live. Racial prejudice comes from ignorance, and Christians should be leaders in demanding equality for all people.

Dinosaur Train and Reality

Dinosaur Train and Reality
I have been blessed over the past year with a two-year-old who calls me “Booh” which is Thai for “Grandpa.” It has been a wonderful experience for me in several ways. One of the things I have learned as he has grown older and watches children’s television is how much bad good and bad information children are exposed to in their preschool years. My adopted grandson’s favorite television program is a PBS Kids series called Dinosaur Train.

The program opens with a small pair of creatures that look like pterodactyls standing by a nest containing four eggs. The eggs hatch and the first three hatchlings look like their parents, complete with the ability to fly. The fourth egg hatches a few seconds later with a baby who looks nothing like the parents and who says, “What am I doing in a flying reptile nest?” The mother dinosaur picks up the baby, and the whole family flies to a train station called the Dinosaur Train.

On the train, a conductor takes the family on a trip to different geologic time periods–Mesozoic, Cenozoic, Paleozoic, Triassic, etc. There the family meets dinosaurs from the various time periods who explain what they eat and how they find their food. The train has a cattle car with large dinosaurs in it, and the family goes to a coach containing smaller dinosaurs.

Occasionally a scientist identified as a paleontologist presents a mini-lecture. The lecture may be on the meaning of words, the current evolutionary beliefs about the animals, or the geological processes that shaped the history of the Earth. His presentations are generally accurate, and he attempts to give the viewers a vocabulary that would be the envy of most college freshmen. Sound effects are very entertaining, and the program stays away from blood and gore and tends to focus on herbivores.

There are lots of concerns that parents may have about the current geologic and evolutionary beliefs that are presented as facts. I am concerned about the anthropomorphism of the dinosaurs. The train is a mid-twentieth century coal-burning steam engine and the train station is from the same time period. The conductor is a dinosaur wearing an outfit that looks like a circus barker. He not only calls the “All aboard,” but he gives Powerpoint-style explanations. The dinosaurs all speak perfect English and behave as humans. Everyone is friendly, T-Rex speaks kindly with everyone, and groups of dinosaurs sing Broadway-style tunes. Dinosaur Train is quite frankly very entertaining.

The problem I have is that the dinosaurs are essentially humans, engaging in human contests, doing human things, and having human relationships. Mom and dad have human roles and enjoy human activities like picnics and visits to different climates and places of recreational value. It is no wonder that those who tell children that humans and dinosaurs lived together find a ready audience of young people. I have hunter friends who dislike the story of Bambi because it vilifies hunters and fails to present children with the importance of balance in nature and the role that carnivores like ourselves serve. The same difficulty is present when people don’t understand the role that dinosaurs had in preparing the Earth for humans by supporting the ecology that produced the resources we need to survive on this planet.

Dinosaur Train is interesting and creative, but parents need to take time to give more accurate and realistic teaching to their toddlers as they get old enough to understand. There is no problem in explaining the role of dinosaurs if we understand how God designed and planned for humans from before time began.

Evolution Weekend and Darwin Day 2018

Evolution Weekend and Darwin Day 2018
February 12 has been designated as Darwin Day by the U.S. government with Senate Resolution 374 and House Resolution 699 both being pushed by the American Humanist Association. The stated goal is “..support of designating February 12, 2018, as Darwin Day and recognition of Charles Darwin as a worthy symbol of scientific advancement on which to focus and around which to build a global celebration of science and humanity intended to promote a common bond among all of Earth’s people.” With Darwin Day comes the return of Evolution Weekend in which various churches use the weekend of February 9-11 to promote their view that “evolution is sound science and poses no problems for their faith.” The Clergy Letter which Michael Zimmerman circulates among denominational congregations states that “Evolution Weekend makes it clear that those claiming that people must choose between religion and science are creating a false dichotomy.”

All of this is a strange mix of good ideas and bad ideas along with fact and opinion. It is also replete with attacks on the Bible and denigration of those who claim that bad science is involved. The stated goals are wonderful. The failure to define what is meant by evolution and accurately present what Charles Darwin actually discovered dilutes the value of the weekend and of Darwin Day itself.

It would be wonderful if Darwin Day not only commemorated the birth of Charles Darwin but presented his primary discovery. What Darwin discovered was that living things are designed so that they can change and adapt to environmental conditions and changes humans make to improve crops and animal husbandry. Unfortunately, atheists attempt to add the writings of those who oppose the idea that humans are special. Instead, they suggest that all of life has equal value because they deny the spiritual dimension of humans.

It would also be wonderful if, on evolution weekend, religious bodies would present to their constituents the evidence that claimed conflicts between science and the Bible do not exist. The conflicts are caused by bad science or bad theology–not because of what the Bible actually says or what science has factually proven to be true.

Unfortunately many members of the clergy, such as the “Jesus Seminar,” join the atheists in denigrating the Bible by suggesting that it is full of errors. The National Center for Science Education reports that 182 congregations in 42 states are participating in Evolution Weekend. That is a very small percentage of American churches.

Bird Brainpower

Bird Brainpower
In the February issue of National Geographic, there is a fascinating article about what birds can do. The skills of bird brainpower include puzzle solving, using tools, studying others, vocal learning, socializing, remembering, and social playing.

These abilities are all related to the size of the forebrain compared to the total brain mass. Bird brains vary enormously. Some species such as ravens have very large brains with 80% of the brain involving the forebrain compared to a pigeon having a very small brain with only 48% in the forebrain. In some cases, birds work together pooling their bird brainpower with each having a different role. Some birds prefer certain kinds of music while others seem to show empathy.

It is important to understand that some scientific questions could be raised about the claims that the article makes. In one case, for example, when air was blown on a chick’s fathers, the mother’s heart rate increased. The investigators claimed that shows empathy. A strong wind can be dangerous to any bird. So the question is whether the mother was feeling empathy for the chick or was she concerned over the cause of the wind and what it might do to her.

The article also mentions a cockatoo who rocks in time to the Backstreet Boys tune “Everybody” and a starling who “is happiest when his owner is playing a classical movement on the piano.” The article says the starling likes Mozart, Beethoven, Schubert, and Bach. However, it doesn’t say how you measure starling happiness, or what the owner likes and repeatedly plays in the bird’s presence.

It is a fact that birds show high levels of certain kinds of intelligence, and they can do things that seem almost human-like. However, the things birds can do are not attributes which the Bible ascribes to humans. Many animals are intelligent and can learn from humans, so it is easy to see how the characteristics discussed in the article help the bird survive.

The attributes of being created in the image of God, which is how the Bible defines humans, do not involve any of the characteristics in the article. The creation of art, the creation of music, and the expression of worship are human functions. Also, the expression of the”agape” type of love which does not promote survival or have sexual connotations is a human trait. We don’t see the capacity to be sympathetic and compassionate in these interesting studies of bird brainpower.

The more we learn about the creatures in the world around us, the more we are amazed at the design built into their DNA. This design allows living creatures to navigate, occupy environmental niches, and reproduce in amazing ways. It is all part of knowing that God exists through the things He has made. (Romans 1:18-22)

Life Adapts to a Sealed, Poison Cave

Life Adapts
In southeastern Romania in Constanta county near the Black Sea scientists discovered a cave that had been cut off from the outside world throughout history. Yet, even in a sealed, poison cave, life adapts.

Scientists estimate that the cave was sealed off 5.5 million years ago, and its air is low in oxygen (10%) and high in carbon dioxide (3%). That is almost one-third the amount of oxygen and 100 times more carbon dioxide as the air we breathe. The air and water in the cave also contain high levels of hydrogen sulfide and ammonia. The cave is named Movile Cave, and it is full of life. Biologists have identified 48 species, and 33 of them are found nowhere else.

The food chain in the cave is based on chemosynthesis using sulfur instead of photosynthesis which requires sunlight. Bacteria which oxidize sulfur and methane release nutrients used by other bacteria and fungi. They, in turn, create microbial mats on the cave wall. Those mats are grazed by herbivorous creatures which are consumed by carnivorous creatures such as spiders, leeches, and water scorpions. Contrary to what the media has reported, life didn’t start in the cave. Instead, life has adapted to the cave environment.

Scientists have found life around thermal vents deep in the ocean and under the Arctic ice. We find it amazing that life adapts to hostile environments. We also believe this is a demonstration of the wisdom involved in life’s design. And in spite of what the media have reported, this is not necessarily an argument in favor of life under the crust oceans of Europa and Ganymede, the moons of Jupiter.

Anthropomorphism Extreme

Anthropomorphism
It is very easy to anthropomorphize the behavior of animals. According to Wikipedia anthropomorphism is, “the attribution of human traits, emotions, or intentions to non-human entities…It is considered to be an innate tendency of human psychology.” When your dog cowers after you scold it for doing something, is the dog indicating guilt or remorse? It may look that way, but it may be that the dog has learned that by showing that behavior it will receive less scolding.

There has been an upsurge of scientific material suggesting that humans are not unique in their expressions of grief, guilt, patriotism, devotion, love, hate, etc. Several books have been written promoting the view that no human emotion is missing from members of the animal kingdom. How Animals Grieve by Barbara King and Beyond Words–What Animals Think and Feel by Carl Safina are two examples. There have also been numerous articles in scientific journals promoting anthropomorphism.

The problem is that it is very difficult to avoid anthropomorphism of animals. Frequently we see articles describing how an animal reacts to the death of its offspring. A recent magazine has pictures and discussions of giraffes, whales, dolphins, elephants, gorillas, baboons, chimps, and zebras seeming to grieve at the death of an offspring or a mate for periods of days. (National Wildlife magazine for February-March 2018 page 30-39) The question is whether this is an evolutionary trait of all life and humans are just more highly evolved, or whether we are anthropomorphizing the behavior we see. We have all been influenced by Disney with stories like Bambi, so the question is complicated.

The biblical definition of humans is that we are the life-form created in the image of God. We see that image reflected in the things that humans do that are not physical in nature. We worship. We create art and music and express our emotions in art and music. We feel sympathy and experience guilt. We have an agape type of love that is unrelated to reproduction or survival. We can be taught to think. These properties are made possible by our spiritual nature. We can debate whether all of these characteristics are really unique to humans or whether they have survival value, but our uniqueness as a species is not a function of our intelligence or any physical characteristic.

The difficulty in interpreting animal behavior is that we cannot easily ascertain the role of instinct. Reproduction in animals is instinctively driven. In most mammals the role of the female is determined by her reproductive capacity. It is the lioness that drives the pride, not the male lion. The wonderful work that has been done on gorillas and chimpanzees has shown the role of reproduction in determining the social structure of the entire troop. Study of baboons and chimps shows that stress hormones called glucocorticoids increase when a close relative dies. The release of the hormone oxytocin which inhibits glucocorticoid increases when there is physical contact with other partners after the death of a close relative. What we see in animal behavior is the result of the instinctive drives being disturbed.

There is no question that animals think and that they have emotions, but we should avoid excessive anthropomorphism. Animal emotions are tied into their instinctive drives–not to political or religious values. We suggest that those instincts are part of the design of these animals which provides them with the greatest probability of survival.

The unique nature of all humans should motivate us to value human life. We are not instinctively-driven robots that obey the drives built into our DNA. We can change the world in which we live both physically and spiritually. Valuing all human life and working together to solve the conflicts that divide us is a necessary product of understanding our spiritual uniqueness. When Jesus taught us to love our enemy and to do good to those who do evil to us, He was calling us to express that which makes us human–our spiritual nature created in the image of God.
