Eugenics and CRISPR

Eugenics Logo 1921
In 1927 Supreme Court Justice Oliver Wendell Holmes stated: “Three generations of imbeciles is enough.” He was explaining the court’s support of a Virginia program of involuntary sterilization in a case identified as Buck vs. Bell. The Virginia law and others like it in other states compelled the involuntary sterilization of those people deemed genetically inferior. More than 60,000 people in the United States were sterilized in compliance with the laws the Supreme Court upheld. It was connected to the eugenics movement.

The concept of eugenics goes back at least to the ancient Greeks, but it became a popular movement in Europe and North America in the early twentieth century. In 1931, advocates of eugenics, the movement to improve the genetic quality of the human population, held a “Better Babies” contest in Washington D.C. to popularize the movement. Adolf Hitler used the concept of eugenics to justify his promotion of one superior racial group and to eliminate the inferior groups.

Now in 2018, the concept of using science to produce superior human beings is even more realistic. That is because of a gene-editing tool called CRISPR which geneticists can use to manipulate DNA to control the traits of animals, plants, and people. Dr. Henry Greely of Stanford University says that CRISPR “might one day be used to engineer humans who are more intelligent, beautiful, or athletic.”

It is essential to understand that the potential for good with CRISPR is enormous. It may be possible to cure genetic diseases by using gene editing techniques. It may also be possible to produce useful new food sources. The problem is that gene editing can also be used for evil purposes. Dr. Greely’s statement brings to mind Adolph Hitler’s justification of the extermination of what Hitler considered to be inferior humans.

So what will CRISPR be used for – enormous good, or enormous evil? The answer to that cannot come from science. The religious convictions of those doing the research and those who use the research will decide whether CRISPR does good, or whether it will become a tool of war and ethnic persecution.

Virtually every significant discovery of science can be used for good or evil. Nuclear energy has the potential for enormous good by providing unlimited energy to everyone on the planet. It also has the potential for immense destruction. Dr. Jennifer Doudna at the University of California, Berkeley, is one of the inventors of CRISPR. She has written that she has nightmares “of all the ways in which our hard work might be perverted.”

It is essential that brilliant young Christians become involved in science. They must be involved not only in the research but also in how to use the products of the research.

Hydrogen Wall and Creation

Hydrogen Wall and New Horizons
One of the interesting hints in the Genesis account is the suggestion that two creations were involved. A new scientific discovery of a hydrogen wall may also suggest that.

Genesis 1:1 uses the Hebrew word erets (earth) in describing the creation of the cosmos. “In the beginning God created the heavens and the earth.” That would suggest the simple idea that God created everything including all of the galaxies and whatever else exists in interstellar space.

In verses 9 and 10 the same word (erets) is used in a more restricted way: “And God said, ‘Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. And God called the dry land earth…” This second creation is what the creation week describes with humans and their domesticated animals as the focus of that week.

As the New Horizons spacecraft was leaving the solar system, it encountered what appears to be a hydrogen wall at the edge of our solar neighborhood. As our Sun moves through the galaxy it produces a stream of charged particles called a solar wind. This “wind” collides with uncharged hydrogen atoms producing a wall of hydrogen. This bubble or wall is about 100 times further from the Sun than the Earth is. The wall indicates that our planet and its solar system are isolated as a unit from the rest of the cosmos.

This new data on a possible hydrogen wall reinforces the biblical picture of God’s action during the creation week as a very special action on a very special planet. God created the cosmos, but then He set Earth apart as a place for those creatures created in His image. That is the primary message of Genesis.

Science Credibility and Media Reporting

Science Credibility
Can you trust scientific reports? The Week for September 14, 2018, featured an article about a two-year study of scientific experiments reported between 2010 and 2015. The purpose was to examine science credibility by seeing if the studies contained bias by the researchers. In other words, were the researchers trying to prove their theories by finding false positives.

The people conducting the study examined 21 high-profile experiments and found further research confirmed only 13 of the 21. The problem here is not science, but the way funding is done and how the media treats research reports. To get funding, you have to get results. The media reports flashy results which people use to back up what they want to believe. A headline describing the results of a research study may appear in the media and get worldwide distribution. When later scientific investigations find the result was incorrect, the media rarely reports that the first study was bogus.

This is actually the way science works. Scientists distribute their findings to other researchers who duplicate the study. If they cannot replicate the results, they report it. The media often picks up the first study but not the later research that disproves the first. An interesting example of this was a report on the beneficial results of drinking alcohol. Several studies suggested beneficial effects from drinking small amounts of alcohol, but follow-up studies showed that as little as one drink a day increases the incidence of health problems.

The same page in The Week that reported on science credibility issues contained the information on alcohol dangers along with follow-up data on the damaging effects of marijuana. Some journals do well in reporting all the new data, and periodicals and websites like this one can point out some of these issues. However, we all need to be careful not to take a sensational headline in a major newspaper as proof of anything until later studies have verified it.

Paul warned Timothy to avoid “profane and vain babblings and oppositions of science falsely so called”(1 Timothy 6:20 ). Any opposition to God will be false science, because the Creator of the knowledge we have will never contradict that knowledge. (Read Proverbs 8:22-36.)

What Is Light?

What Is Light?
A question that scientists cannot fully solve is the nature of light. What is light? Is it a wave or is it a particle?

Light has wave properties. It travels in straight lines, but it can be reflected from objects like mirrors, or refracted as it travels through objects like water or glass. Different frequencies of light waves are bent in varying amounts by a prism to show the colors of the spectrum. Light, like sound waves, can travel through gases (air), through liquids (water), or through solids (glass).

But light can also do something that waves normally cannot do. Light can travel through empty space. Because of that and other properties of light, we say that light consists of particles called photons, which act as if they have mass. Photons can knock electrons out of crystals in what we call the photoelectric effect. That’s how solar panels generate electricity from sunlight. So light in motion seems to have mass since it can pass through a vacuum or knock electrons out of their orbit. However, when we stop light, it has no mass. If you shine a light on an object, the light doesn’t make the object any heavier.

What is light? While science ponders that question, we use light every day, and we couldn’t live without it. The question of how light can have properties of both a wave and a particle has baffled scientists for centuries. Even though that answer to that question may never be fully understood, we continue to enjoy and use it every day.

We can see that the simple phrase “let there be light” (Genesis 1:3) is an incredibly complex command.

Troposphere and Breathing Comfort

Troposphere and Breathing Comfort
Earth’s atmosphere is incredible! There are three primary layers of the atmosphere, and we live in the bottom layer called the troposphere. It extends as high as about 33,000-43,000 feet (10-13 kilometers). This layer is where we have breathable air. Above the troposphere is the stratosphere and above that is the mesosphere.

The troposphere is not only where we have air we can breathe, but it is also where we have weather and clouds. In the stratosphere, the air is not dense enough to supply us with sufficient oxygen, but it is relatively peaceful with little turbulence. In the early days of commercial airplane flight, because of turbulence in the troposphere, many people became airsick. However, planes could not fly above the troposphere because, among other problems, the low air pressure in the stratosphere would create a lack of oxygen for breathing.

That changed in the 1930’s when the Boeing company designed the first successful airplane with a pressurized cabin. They called it the “Stratoliner.” It could fly above the turbulence and still provide breathing comfort. Today commercial passenger planes fly in the lower stratosphere for cruising comfort, with pressurized cabins for breathing comfort.

When the weather on Earth becomes turbulent, we sometimes complain, but we can be thankful that the Designer of the Earth gave us a pressurized zone. With each breath we take, we should be thankful.

International Dateline Where Days Divide

International Dateline Where Days Divide
Because the Earth is always turning on its axis, we have periods of day and night. To establish consistent times for daylight and darkness, humans have divided the Earth into 24 time zones. At one point we call the International Dateline, the days divide.

As you travel around the world east to west, the time becomes earlier. As you go west to east, it becomes later. In the United States, the time on the west coast is three hours earlier than the time on the east coast. At some point on the Earth, the time has to change by 24 hours. We call that the International Dateline (IDL) and it runs from pole to pole through the middle of the Pacific Ocean. A new day, or a new year, always arrives first on the west side of that line. Then it progresses around the Earth, hour by hour until it returns to the east side of the IDL.

The Earth always has day and night at the same time because it’s a rotating sphere. People in antiquity didn’t understand that. Also in ancient times when people did not have electric lights, they worked only during the day and slept at night. However, 2000 years ago Jesus talked about an event that will take place in an instant, but he said that it will be daytime and it will be nighttime. He also said that some people will be working (daytime activity) and others will be sleeping (nighttime activity) when the event takes place.

You can read the words of Jesus in Luke 17:30-35. How did He know that day and night take place at the same time? I think it was because he was more than a man. In fact, I believe He created day and night. (See John 1:1, 2, 14.)

Circadian Rhythm of the Biological Clock

Biological Clock and Circadian Rhythm
Living things, both plants and animals, have a biological clock that is extremely important for survival. The human master clock is located in the hypothalamus of the brain in a tiny region called the suprachiasmatic nucleus (SCN). The SCN controls what is known as the circadian rhythm, a 24-hour rhythm of the body.

The SCN interacts with many regions of the brain to control sleep, hormone levels, alertness, body temperature, digestive activity, immune functions, and other systems. It coordinates the various rhythms of the body to keep us going through the day. This biological clock works in many ways that we don’t even realize.

Specialized cells in the retina of the eye connect directly to the SCN. When the eye senses light, the SCN receives the message and starts body process going by telling the various systems what to do and when. When you wake up in the morning, the clock signals enzymes to start flowing for your first meal. Hormones raise body temperature and blood pressure so that you can face the day.

During the day, the biological clock starts various chemicals and hormones so they will be available and functioning when they’re needed. Therapeutic medicines work best when taken at certain optimum times according to the biological clock. At night the circadian rhythm in the SCN sends a message to the pineal gland to produce the hormone melatonin making us sleepy.

This is a highly-simplified summary of an amazingly complicated system. Complex systems like this don’t happen by chance indicating that this is another evidence of design. Day and night, months and seasons regulate the systems of humans and all other creatures. Genesis 1:11 tells us that God made the Sun and Moon to “mark seasons and days and years.” Those simple words contain profound truths that we have only begun to understand.

Honeybee Engineering

Honeybee Engineering
Bees are master engineers of the storing of dense fluids. Their fluid is honey, and they store it in a way that shows excellent honeybee engineering.

Worker bees gorge on honey and excrete slivers of wax. Other workers take that wax and position and mold it into a column of six-sided cells. The bees cluster to keep the temperature of the wax at 35 degrees C (95 degrees F) so that it’s firm but malleable. Each wax partition is less than .1 mm thick with a tolerance of .002 mm. The cell walls must be at a 120-degree angle in relation to each other to make a lattice of regular hexagons.

There are only three regular polygons which pack together snugly without leaving gaps–equilateral triangles, squares, and regular hexagons. The perimeter of a hexagonal cell that encloses an area is less than that of a square or a triangular cell making it the most economical shape. Using the same quantity of wax, hexagonal cells can hold more honey than square or triangular cells. Mathematicians have tried other options, such as using curved sides or a mixture of polygons. They have confirmed that curved polygons could not do as well as straight-line hexagons. Mathematicians can’t beat honeybee engineering.

How do the bees keep the honey in the cells? They tip the cells upward at an angle of 13 degrees from the horizontal. That is precisely the angle needed to stop the honey from dripping out. There is one more problem. How can the bees seal off the bottom of the columns? A flat bottom would not do. Bees construct the base with three, four-sided diamond shapes that meet in a point. Two rows of cells are placed back-to-back and offset so that they interlock. With the cells backing up each other, only one layer of wax acts as the bottom for both cells. Mathematicians have proven that the angles of the diamond-shaped cell bottoms (109.5 and 70.5 degrees) give the maximum volume for storage.

It’s difficult to believe that the honeycomb structure is an accident or the final product of trial and error. Mistakes are usually lethal or at least result in a loss of vital energy resources. Honeybee engineering has fascinated and amazed philosophers and mathematicians since the time of ancient Greece. We think the honeybee engineers learned the principles of structural math from the Master Engineer.

Canyonlands Field Trip Purpose

Canyonlands Field Trip

Today is the final day of the 2018 DOES GOD EXIST? Canyonlands Tour. The pictures are of Bryce Canyon and Alan Doty who has served as a guide along with John Clayton. They have been making these educational tours for several years. The purpose of the Canyonlands field trip is not just entertainment. We want to help people understand the history of how God has crafted the Earth He created to make it a suitable home for people. We also want to show that science and faith are friends, not enemies. This video is from an earlier journey to the Canyonlands. We share it here so that John can tell you why he believes these trips are important.

You can watch the video series John mentions by using THIS LINK.
We also invite you to see our two previous posts about the Canyonlands Field Trip HERE and HERE.

Intelligent Design or Beneficial Accidents?

Intelligent Design or Beneficial Accidents?
An atheist once said, “We are as much a product of blind forces as is the falling of a stone to earth or the ebb and flow of the tides. We have just happened, and man was made flesh by a long series of singularly beneficial accidents.” The other view is that we are the result of design and planning. Do you consider yourself the result of intelligent design or beneficial accidents?

C. S. Lewis, an atheist who became a believer, wrote, “If the solar system was brought about by an accidental collision, then the appearance of organic life on this planet was also an accident, and the whole evolution of Man was an accident too. If so, then all our thought processes are mere accidents—the accidental by-product of the movement of atoms. And this holds for the materialists’ and astronomers’ as well as for anyone else’s. But if their thoughts—i.e., of Materialism and Astronomy—are merely accidental by-products, why should we believe them to be true? I see no reason for believing that one accident would be able to give correct account of all the other accidents.”

We suggest that you ask yourself this question: “Can I rationally believe that the incredible complexity of my body is the result of mindless forces, or does it indicate design?” If our thoughts are merely accidental byproducts of the movement of atoms in a brain that accidentally assembled itself, then nothing has any real meaning.

At DOES GOD EXIST? we believe that we are not accidents. The human body exhibits evidence of design, not chance accidents. Our thoughts are rational because we are the product of a rational God. Intelligent design or beneficial accidents — which do you choose?
