Cotyledon’s Engineered Preparation for life

Cotyledon’s Engineered Preparation for lifePlant seedlings emerging from the ground use the cotyledon’s engineered preparation for life. You may not be familiar with cotyledons, but you have undoubtedly seen them on newly emerged seedlings.

To get the idea, think about some other engineered devices that serve an essential preparatory function. When skydivers jump from a plane, they use carefully engineered equipment. The first thing they deploy to prepare for landing is a pilot chute. The pilot chute can’t land them safely on the ground. Its purpose is to deploy the main parachute. Perhaps more familiar to most people is the limited-use spare tire for automobiles. Those “donuts,” as many people call them, are not designed for high-speed driving or for driving long distances. They are engineered to get you to the nearest service station where the punctured tire can be repaired or replaced. The pilot chute and the limited-use spare tire are examples of engineered preparation.

Just as the pilot chute is packed into the jumper’s gear and the donut is packed into the vehicle, there is something packed into the seed called a cotyledon. Scientists classify flowering plants (angiosperms) as monocots or dicots depending whether they have one or two cotyledons folded into the seed. As soon as the seed has sent a taproot into the soil, it pulls in moisture and uses the hydrostatic pressure to push up a green shoot bearing the cotyledons. As those “donuts” break through the surface, they inflate to provide temporary, emergency photosynthesis. The seedling begins to drink up the water and nutrients from the taproot and use energy from sunlight to kickstart the photosynthesis process.

As the cotyledon’s engineered preparation for life gets the new plant started, real leaves begin to form. In a sense, the cotyledons have taken the plant to the first service station or deployed the main chute. Now it is ready to go from a seedling to a full-grown plant or tree. The seedling still has many challenges ahead, just as the parachutist or motorist does. But just as having the pilot chute or the donut packed and ready for deployment aids the jumper or the driver, the cotyledon supports the plant. Would anyone suggest the pilot chute or donut are merely accidents? We know those devices would not be possible without engineering design. In truth, cotyledons require far more complex engineering that only the master Designer can do.

Would E.T. Live by the Bible?

Would E.T. Live by the Bible?The movie E.T. has been getting a revival of interest because of a renewed interest in UFOs and claims of alien visitation. The media has given much attention to exoplanets – planets orbiting stars other than our Sun. With all this attention to life in space, it is no wonder we get the question of whether they would follow the teachings of Christ. “Would E.T. live by the Bible?” is mostly idle speculation, but there is a point to be made.

We have made the argument that the teachings of Jesus show wisdom and design beyond that of mere humans. You can’t take the Sermon on the Mount in Matthew 5–7 and not see that if all humans lived by those standards the Earth would be at peace and most of our problems would be gone. Even from a purely intellectual standpoint, it seems that an advanced civilization would have come to the point of realizing that war, fighting, selfishness, and greed are destructive and should be weeded out of the culture. Would E.T. live by the Bible? He would if he is smart.

I am reminded of a radio debate I had many years ago in Washington D.C., moderated by Larry King. The atheist representative was advocating humanism, but he and I were finding a lot to agree on. The show came to a halt when a listener called in and asked the atheist, “What would you do if a little green man landed in the Whitehouse lawn in a flying saucer, got out with a Bible in his hand and said ‘Has Jesus Christ been here yet?’” My atheist friend responded, “Punt.”

Formation of the Grand Canyon

Formation of the Grand CanyonFor many years science has studied the formation of the Grand Canyon. No single event produced the carving of the canyon. The north rim is higher than the south rim because the whole area has been bowed into what is called a monocline. Such flexing weakens rock just as bending a stick will weaken it at the point of maximum bending. In addition to bending and cracks which weaken sections of rock, water in the area is flowing toward the sea. The Colorado River flows in a path that wanders and winds through the area scouring its bed as it goes. Streams flow into the Colorado flow along the faults through weakened rock materials carving deeper and deeper. All of these things contribute to the formation of the Grand Canyon.

Another obvious contributor is time. How much time did it take to carve the canyon? Some science books will point out that the Colorado River is currently eroding one-half foot of rock every 1,000 years. Then they suggest that if you take the 5,000 feet of vertical rock missing from the canyon and divide it by .5 feet, it would take 10,000 of the 1,000-year-periods. In other words, it would take 10,000,000 years to carve the canyon.

What is wrong with that estimate? Well, first of all, the river is in granite now, which is harder than the sedimentary rocks above it. More important is the assumption that the volume of water in the canyon has been constant. In the past, glaciers melted, producing massive volumes of water in the canyon. Today with the Glen Canyon Dam and Lake Powell controlling the flow (except in a simulation of spring floods), no such volume takes place. Estimating the time required to carve the canyon based on present erosion rates is a self-evident case of bad science.

Another example of bad science comes from creationists who point to Mount St. Helens in the state of Washington as an indication of the time required. Mount St. Helens erupted in 1980 blowing out massive amounts of ash, scoria, pumice, and other extruded volcanic rocks. Erosion produced vast canyons on the flanks of the mountain in a few years. Those who say that proves large canyons can be carved in a short time are overlooking the fact that the volcanic rocks are relatively light, easy to erode, and highly porous. To make comparisons between the Grand Canyon and Mount St. Helens is like comparing butter with steel. (For more on this, click HERE.)

So how long did the formation of the Grand Canyon take? No one can answer that question, just as no one can tell you the date of Genesis 1:1. Only those willing to add to the Word of God will give a date. Many denominational creationists will do this to defend their human creeds and traditions, but I suggest that it is a dangerous thing to do.

What we see in the Grand Canyon is an incredible testimony to the power, patience, wisdom, and design of God. In His creation of the Earth, God has produced the elements He knew we would need. He has engineered a planet that processes and redistributes those materials in such a way that they are always available. The Grand Canyon gives us a glimpse of the inside workings of this great machine we call Earth. Genesis 1:1 tells us God created it, not how or when – or how it works. But God has given humans a curiosity, so we look for answers to the formation of the Grand Canyon. The important thing for us to remember is, “God saw all he had made, and it was very good” (Genesis 1:31).

Ghostly Seadevil Finds a Mate in the Dark

Ghostly Seadevil Finds a Mate in the DarkMore than a mile (2250 meters) below the ocean, there is a world of darkness. Finding a mate in that dark place could be a challenge, but a species of anglerfish with the scientific name Haplophryne mollis has the problem solved. The solution is to keep your mate permanently attached. The so-called ghostly seadevil finds a mate in the dark and doesn’t let go.

The female sends out pheromones, chemicals which attract the males. The males, which are much smaller than the females, have a keen sense of smell to detect the pheromones in the water. Ghostly seadevils are called anglerfish because they have a “fishing lure” in front of their face to attract other fish which they eat. In the case of the ghostly seadevil, only the female has the lure, and it’s bioluminescent, meaning that it glows in the dark.

Once the male has detected the pheromone, he looks for the glowing lure. He examines the shape, color pattern, and flash pattern of the lure to tell if this is a female of his same species. If it is, he clamps onto her with his teeth and doesn’t let go. Eventually, their skin grows together, and their blood vessels join. She provides his nourishment, and he fertilizes the eggs which she lays. The eggs float upward to the ocean’s surface where they hatch, and the larvae feed on plankton. As they mature, the seadevils migrate back down into the ocean depths and repeat the cycle of life.

This is a drawing because pictures are hard to get in the dark ocean. In this case, you can see that two males have attached themselves. You can also see the bioluminescent lure on the front of the female fish’s head, and that’s how the ghostly seadevil finds a mate in the dark. They have a “ghostly” appearance because their bodies are translucent like many creatures living in darkness. This cycle of life seems strange, but it has too many coincidences to be accidental. We think it shows the creativity of the God who designed life to survive everywhere on Earth.

God’s Creation Method for the Moon

Gods Creation Method for the MoonAstronomy magazine (November 2019, page 44) has an interesting article on some of the facts about the Moon. The information is based on the 842 pounds (382 kg) of rocks brought back from the Moon by the Apollo astronauts. Every time an issue of this magazine comes out, I have two groups of people who like to write to me with their analysis of the meaning of an article in the magazine. (We also have several who do the same thing with other scientific magazines and journals.) The discussion of the letter writers has to do with God’s creation method.

One of the people wrote that this Moon data clearly shows that God had nothing to do with the creation of the Earth or the Moon. The other person tried to deny the data maintaining that God “spoke the Moon into existence,” and it was not a natural process. Both of these writers miss the point.

First, there is no reason for believers in God to challenge the scientific data in the article. In this case, the ratio of the isotopes of oxygen in Earth rocks and Moon rocks are the same. The average high school physics student can tell you how that measurement is made and how reliable it is. Earth’s spin axis and the Moon’s orbit are related, and once again, basic physics equations can verify that data. There is no reason to question the data. That data led to the impact hypothesis that the Moon was formed when a Mars-size body impacted the Earth and threw off debris which coalesced into the Moon. There is no reason to feel that somehow those facts deny the existence of God or the description given in the Bible.

The Bible simply says that God created the heaven (“shamayim” – the Hebrew of Genesis 1:1) and the Earth (“erets”). It does not describe God’s creation method. Verse 14 tells us, “God said, Let there be lights in the expanse of the sky…” In verse 16, this is expanded with the words, “God made (“asah” in Hebrew meaning He made or fashioned what already existed) two great lights …” Then it says that He “…let them be lights in the expanse of the sky to give light on the earth.” The material is created in verse 1, where “bara” is used indicating an act that only God can do. The fashioning “as signs to mark seasons and days and years” in verses 14-18 uses the Hebrew “asah,” not “bara.” Genesis 2:3 tells us that God “rested from all his work which God created (bara) and made (asah).” Both processes are involved.

What science is trying to do is understand God’s creation method to fashion the Moon, which is discussed in verses 14-18. This Astronomy article is not trying to understand what He did in verse 1. Sound waves coming from the voice of God did not create the Moon. Whether God spun the Moon out of the cloud of matter from which He formed the Earth, or whether He formed the Moon by a collision, is still being debated by scientists. Whatever opinion one might hold is an opinion of God’s creation method – how He did what He did. It does not in any way reflect negatively on His power and creative ability or on the biblical description of what God did to give us “two great lights.”

Ten Percent of People Are Gay?

Ten Percent of People Are Gay?You have probably heard the statistic that “ten percent of people are gay” or even “ten percent of people are BORN gay.” The truth is that nobody is “born gay.” There is a condition called “intersex” in which a child is born with some characteristics of both sexes. Those cases are very rare and varied. The different variations of intersex can occur anywhere from one birth in thousands to one in hundreds of thousands. But that does not mean the child is “gay.”

Research and observation seem to indicate that same-sex activity is increasing. Some experts have suggested that the apparent increase in “gayness” in our society is due to environmental pollution. There has been a lot of research into finding a “gay gene” or any environmental factor that makes a person “gay.” So far, there are no reliable answers.

The “ten percent of people are gay” statistic was falsely derived from the 1940’s Kinsey research. Alfred Kinsey, a zoologist at Indiana State University, interviewed people in prisons and the “gay underworld” using methods that would not hold up to modern statistical sampling techniques. He compiled the statistics in his reports on “Human Sexual Behavior” that shocked America. In the 1970s, Bruce Voeller, who founded the National Gay Task Force, used Kinsey’s research to say that ten percent of people are “gay.” That number has become one of the myths of modern culture. (Similar to the myth that we use only ten percent of our brains.) After all, ten percent is a nice round number even if it has no basis in fact.

So what is the truth about the apparent increase in same-sex activity? Reliable research indicates that the percentage of people in the overall population who consider themselves to be gay/lesbian/bisexual is much lower than ten percent. However, whatever the percentage, it is higher among young people. How much of this is a factor of family breakdown, media and celebrity influence, or society’s acceptance of the “gay lifestyle” is difficult to determine.

It is interesting to consider the consequences if “ten percent of people are born gay,” and the concept of human evolution and “survival of the fittest” is correct. In that case, “gayness” should have evolved out of the human population since same-sex relationships can’t produce children to pass on their traits. At the very least, it should be decreasing rather than increasing. After the flood, God told the few survivors to “be fruitful and multiply” (Genesis 9:7). That is one of the few commands of God that humans have kept. Satan tempted the first couple to disobey the first command God gave them to not eat fruit from one of the trees. Perhaps through abortion and same-sex relationships, Satan is trying to get people to disobey the only remaining command of God that humans have thus far kept.

How the Elements Were Created

How the Elements Were CreatedScience has made significant progress in understanding many things about the universe and our planet and the life on it. However, there are many, many things that we have not yet begun to understand. There are also many things we think we understand, but we are still working on better understandings. One question involves how the elements were created.

At the time of the cosmic creation event (widely called the “big bang”), there were atoms with one proton and one electron and some with twice that many. We call simplest element hydrogen, and two hydrogen atoms combine to form helium in the process of nuclear fusion. More and more fusion took place and still is happening in our Sun and other stars. The process requires intense heat and pressure to fuse the atomic nuclei into a heavier atom.

In stars much more massive than our Sun, heavier elements up to iron can are being formed by fusing more and more atoms together. When you go beyond iron, and all the way up to uranium, even the biggest, brightest, and hottest stars can’t squeeze those atoms together. Scientists believe that the heavier elements are created in exploding stars known as supernovae. When they explode, the theory goes, ripples of turbulence form as the supernovae toss their stellar material into the void of the universe. The forces in that turbulence press more and more atoms together to make the heavier elements. As those atomic elements fly off into space, gravity pulls them into lumps which eventually become planets, such as the one on which we live.

A problem with that explanation is that when the atoms are blasted from the supernovae, they are all traveling in the same direction at perhaps the same speed. How can that produce enough force and heat to fuse them together? An alternate explanation is that the explosion within the supernova is not symmetrical, creating areas of greater density. Ultradense and ultrahot regions concentrated in small areas of the exploding mass perhaps give a better explanation of how the elements were created. (See a paper on that published in the Proceedings of the National Academy of Sciences of the United States.)

Carbon is the basic building block of all living cells. Nitrogen and oxygen, which are the next steps above carbon, bond with it along with other atoms to form living molecules. A little higher on the atomic scale are sodium, magnesium, phosphorus, and other elements which are essential to life. Iron, nickel, copper, and other metals are in molecules within our bodies, and we use them in pure form to build our homes, cars, and electronics. The heavier radioactive elements such as uranium deep within the Earth generate the heat that creates a molten iron core that generates a magnetic field which surrounds and protects us. This is a very simple explanation of a very complex system that makes it possible for us to be here.

Science is only beginning to understand how the elements were created and how they are continuing to be created. How did this amazing, complex system come into being with the precision that put life on this planet? We could declare a god-of-the-gaps to say that we don’t understand it and therefore, God did it. It is much better for us to learn HOW God did it. As we begin to see the wisdom required to put this incredibly complex universe together, we become more in awe of the Creator. We don’t have a god-of-the-gaps who “zaps” things into existence like a magician. Our God is an engineer craftsman who creates complexity and beauty that leaves us without excuse. (See Romans 1:20.)

Not Afraid of Science

Not Afraid of ScienceThe American Scientific Affiliation website published an interesting article by Sara Sybesma Tolsma titled “Science in Church.” Dr. Tolsma is a professor of biology and started her article by saying, “My church is not afraid of science.” The Does God Exist? ministry has tried to nurture that attitude among our readers, so the article was of great interest to me.

What Dr. Tolsma has done is to have an elementary science center in the midweek Bible class. The kids do simple science experiments and then relate them to biblical stories and the concept of God’s design and creative wisdom in the world around us. Because she is a biologist, she had the kids do some experiments with microscopes. They used cotton swabs to wipe surfaces within the meeting place of the Church and then wipe the swab on agar plates which allow bacteria to grow. A week later, they examined the bacteria cultures under a microscope. The kids were shocked at the results. She also led the kids in hand washing experiments using plain water, soap and water, and hand sanitizer to compare the results under the microscope.

The experiments she used can help kids understand God’s hygienic rules for Israel. Helping them see the goodness of the natural world is essential. The kids learn that science is knowledge and the Bible encourages and supports seeking knowledge. These lessons equip them to handle the challenges they will face when people try to make faith an enemy of science. They are prepared to be not afraid of science. Singing “For the Beauty of the Earth,” “How Great Thou Art,” and other songs that praise God for His creative wisdom can build faith. The sessions concluded with a prayer thanking God for all of creation, even those things that you can only see with a microscope.

The conclusion of her article finds Dr. Tolsma saying, “We can reinforce the natural curiosity we see in the kids… and reignite that curiosity in adults so we can all more fully experience Christ, ‘the firstborn of all Creation’ the One in whom ‘all things in heaven and on Earth were made’…the amazing details of God’s natural world declare that the heavens, rocks, plants, animals, and even the microbes are telling the glory of God.”

The Does God Exist? ministry encourages Christians to be not afraid of science. We have a set of materials produced by Jean Wiebe and Pat Parker titled “God Made It All Perfect.” The lessons and ideas are contained in two teacher’s guides. Jean’s materials are designed for grades 1-4 and Pat’s are intended for grades 4–7. There are over 100 pages in each of these 8 ½ x 11 books. We can send these to you free if you will cover the postage and packing, which would be $6.00 for the two or $3.00 for either one. If you are interested, send your check to “Does God Exist?,” PO Box 2704, South Bend, IN 46680-2704.

Hubble Constant and Age of the Universe

Hubble Constant and Age of the Universe
The Associated Press released an article on Friday, September 13, 2019, that read, “Study Finds the Universe Might be Several Billion Years Younger.” The news story sites a study released in the journal Science on September 12. In the study, Inh Jee of the Max Planck Institute in Germany used a new method to measure the Hubble Constant, which scientists use to calculate the age of the universe.

Right away, we have seen some fundamentalists jumping to the conclusion that the headline means the Earth is 6,000 years old after all. The Bible doesn’t tell us how old the creation is. The age of the Earth is a denominational issue for those whose human doctrines won’t work if the Earth is more than 6,000 years old. Our concern is that people understand that this is not an issue about whether God exists or whether the Bible is true.

We can measure the age of the universe by determining the expansion rate of the cosmos, which is the Hubble Constant. Measuring that expansion has been incredibly difficult, and that is what the headline refers to. In previous years the Hubble Constant has been estimated to be 70. Inh Lee and her team used a new technique called time delay gravitational lensing which gave a value for the Hubble Constant of 82.4. That would reduce the age of the universe from the currently accepted 13.7 billion years to 11.4 billion years. Other scientists using other techniques earlier this year have given a Hubble Constant of 74 and 73.3. Previous methods have given a value as low as 67. A lower value means an older universe, and a higher value of the Hubble Constant means a younger universe.

If you know the value of the Hubble Constant, the calculation of the age of the universe is very simple. We all know that travel time depends on two things. If I go 100 miles at 50 miles per hour, how long did I travel? The obvious answer is two hours. Distance traveled is equal to the speed at which you travel multiplied by how long you travel at that speed. We can measure the size of the cosmos by several techniques. Triangulation is difficult because the size is so huge that the apex angle of the triangle is too small to measure accurately. However, triangulation does give us an idea of the vastness of space.

The further light travels through the cosmos, the lower the frequency of the light. That effect is caused by dust particles in space scattering the higher frequency blue light. The effect is called interstellar reddening, and it gives us a good measure of the size of the cosmos. Several other methods involve complex energy production by various stars. All of those methods provide a reasonably consistent measure as to how big the cosmos is. Applying the Hubble Constant to the size of the cosmos provides us with a measure of the age of the universe.

The point of all of this is to get values that science can use to study astronomical processes in deep space. The problem is that our measuring devices are primitive in terms of what we need for such distant objects. What it means to those of us who marvel at the size and complexity of space is that more than ever, “The Heavens declare the glory of God and the firmament shows His handiwork” (Psalms 19:1).

Spring-loaded Movement in Living Things

Spring-loaded Movement in Living ThingsAn interesting study of living things in the world around us involves how things move from one place to another. There are many creatures with muscles that move their legs or wings to travel from place-to-place. Other forms of life use spring-loaded movement with power greater than muscles can provide.

The larvae of the gall midge Asphondylia flip with power by using a built-in latch that acts as a spring. Gall midges lay their eggs on silverrod or goldenrod plants (Solidago). The midges grow from an egg to a larva inside a gall that grows on the plant. The larva’s body forms into an ellipse by meshing together the back and front using a velcro-like surface on each end. As the midge larva grows, the tension on the surfaces increases until it finally breaks free, shooting the midge as far as 36 times its body length. We previously reported on the so-called “Dracula ant” (Mystrium camillae) which has the world’s fastest jaws that operate on a mechanism which gives them spring-loaded movement.

Some plants like the Chinese Witch Hazel (Hamamelis mollis) have a similar structure in their fruit. As the fruit grows, it builds up stress until the edges of the fruit break, shooting the seed great distances. That spring-loaded launch method spreads the seeds over a wider area. Also, we previously reported on the sandbox tree (Hura crepitans) nicknamed “the dynamite tree.” Its seedpods open explosively by a spring-loaded movement that scatters the seeds.

These are all design features built into the very structure of the organisms to allow locomotion. Even the smallest creatures such as ants and midge flies and plants that are rooted in place use spring-loaded movement. Everywhere we look in the creation, we see God’s designs at work. His wonder-working hand has created a great diversity in all of life.

As Paul wrote in Romans 1:20, “For the invisible things of Him (His wisdom, power, and design) from the creation of the world are clearly seen, being understood by the things that are made even His eternal power and deity; so that mankind is without excuse…”
