Amazing Human Eye

Amazing Human Eye
Eyes are among the great challenges to those who insist that unguided, naturalistic evolution created all living things. Eyes are complex devices that display engineering design skill. A significant problem for naturalists is that some very complex eyes appear early in the fossil record, such as the trilobite eye. Each animal has eyes well-designed for the life they live. That is certainly true of the amazing human eye.

Many things about human eyes make them amazing. One of those is the cornea, the clear front covering of our eyes. Corneas must be perfectly clear to allow light to pass through for an unobstructed view of the world around us. Because of the need for complete transparency, they have no blood vessels. Our corneas get their nourishment from the aqueous humor (the liquid inside the eye) and the tear fluid on the outside. They get oxygen from direct contact with the air.

Corneas must be designed to fit a curving surface full of a fluid which maintains the critical pressure inside the eye. However, there is a problem with the cornea being exposed to the air with all of the contaminants it contains – pollen, dust, chemicals, and grit. Corneas can become scratched. Over time, any surface exposed to dirt and grit, and sometimes bumps and blows, can get tiny scratches. How is it possible for corneas to remain transparent with so much abuse?

When you cut your skin, as the cut heals, scar tissue forms. Scratches in our corneas must heal without scar tissue. When the outer layer of the cornea gets scratched, the surrounding cells move toward one another and close the scratch leaving no scar tissue. This is only one feature of corneas which consist of five different layers each having an important function and showing evidence of design.

Think what it would be like if scar tissue formed every time the surface of our corneas got scratched. By the time we reached middle-age, we would certainly be looking through cloudy lenses. If you can read this, you should be thankful for just one of the features of the amazing human eye!

Programmed to Change

Colour Sergeant Butterfly - Programmed to Change
When I was a child, I was introduced to the metamorphosis of a caterpillar to a chrysalis to a beautiful butterfly. I decided to figure out how that change took place, so I cut open a chrysalis to see what was going on inside. Instead of catching the transformation in progress all I found was a capsule of black soup. Later when I asked biologists how the process took place, I realized that no one fully understood it. The caterpillar was programmed to change, but nobody could understand how.

What I did learn was that this process goes on in a wide variety of life forms. Frogs, sea urchins, flying wasps, and beetles are just a few examples of creatures programmed to change. The December 2018 issue of National Geographic features a wonderful article about the use of 3D models and micro-CT scanning of the process. These tools have given us a great deal of understanding of how this transformation occurs. The article identifies three stages of the change that happens as the caterpillar changes into a butterfly.

1. PROGRAMMED ACTIVATION. The caterpillar eats vegetation until it is full grown. As it does so, its hormones begin to shift with some parts of the caterpillar expanding and others becoming degenerate. The thoracic legs grow into legs that are good for grasping. Four wing buds on the caterpillar’s body begin to develop into wings, and the antennae become larger. The silk gland begins to degenerate to become the chrysalis. The proleg degenerates making the caterpillar more dependent on crawling. The mandible the caterpillar uses for chewing begins to degenerate making room for a tube for sipping nectar. The simple eye of the caterpillar which could only detect the presence or absence of light begins to change. All of this is programmed into the genetic makeup of the caterpillar.

2. TRANSFORMATION. As the prolegs degenerate, thoracic legs grow to adult size. Wings develop with full color from the four wing buds. The chewing mandibles morph into two halves that zip into pipes that make a straw-like proboscis. Simple eyes move forward closer to the brain and produce a compound eye which gives true vision.

3. EMERGENCE. The brain of the butterfly is almost completely rewired to meet flight requirements.  One thing that the butterfly seems to retain from its caterpillar stage is olfactory memories. It needs that to know where to produce the next generation of caterpillars. The butterfly sucks in air until its chrysalis breaks open. The butterfly flaps its wings for several hours to dry them and to circulate blood before flying off in search of a mate.

All of this happens in 15 to 21 days. The gut of the butterfly shifts from digesting plants to nectar in that short time. There are wonderful artistic drawings of all this in the article. The author summarizes his study by saying, “..the insect’s makeover is a programmed mix of destruction and growth. Certain cells die, and body parts atrophy. Meanwhile, other cells, in place since birth, rapidly expand in as little as two weeks, the adult emerges completely remodeled, capable of flight – and bent on finding a mate.”

We would add that no programming happens by chance. It takes intelligence to program a computer. The caterpillar programmed to change to a butterfly reflects the wisdom and intelligence of a great programmer superior to anything the software companies can offer.

Artistic Expression and Human History

Artistic Expression and Human History
One of the interesting challenges to human evolution has to do with our capacity for artistic creation. Why do human artistic expressions display beauty and color? There is no good evidence that animals express themselves aesthetically – be it music, color, artistic expression, abstractionism, or worship. When people have claimed that animals express themselves in these areas, the claims have turned out to be anthropomorphisms by those making the claims. We all tend to attach human attributes to animal actions, but the evidence supports the view that animals don’t do those things. On the other hand, artistic expression and human history go together.

One evidence of artistic work has to do with the pictures left on cave walls in various locations. Those drawings do not show a sequence of development. In other words, you don’t see older drawings that are more primitive than recent ones. There is a story that Picasso examined the Cromagnon cave drawings and said, “We have learned nothing about art in our entire history on planet earth.”

USA Today (November 9, 2018) published an article on new art finds in Borneo and Indonesia. They are much older than any of the drawings in Spain and France. Dr. Maxime Aubert who led the discovery says the paintings are 4,000 years older than any other find. Aubert says “they are the earliest known figurative artwork.” In addition to the drawings of mystic animals, there are hand stencils and cave paintings of human scenes, and extensive use of color.

Genesis 4:21-22 indicates that humans developed tools and musical instruments early. Human history has included artwork and musical synthesis from a very early time. We would suggest this is all tied to our spiritual nature. It is our soul that gives us the capacity to do all the things that set humans apart from animals. The new finds support the view that these abilities were present in human’s from the beginning, not developed over a long time. Artistic expression and human history cannot be separated.

Stromatolite – Oldest Fossil or Not

Stromatolite
For many years the textbooks in paleontology classes have said the stromatolite was the first life form to appear on Earth and that its formation was the product of chance biochemical reactions. Now there are some challenges to this model.

There were several reasons for promoting the stromatolite as the oldest life-form. One reason was that it fit evolutionary models and made sense as far as the production of atmospheric oxygen is concerned. The other reason was that a primitive plant which is a form of algae leaves a conical formation of calcium carbonate in the ocean today. Those formations are similar to the stromatolite formations found in ancient rocks. Scientists found those formations in such diverse locations as the Gunflint Chert in Canada, the Isua Belt in Greenland, and the Ediacaran formation in Australia. I have seen the formations in Australia and Canada, and they are very similar and easy to recognize.

It turns out that the formations appear to be volcanic and not biologic in origin. If the conical formations organically originated they should all have the point of the cone pointing up. In at least one recent find, the top of the cone was pointing down. Dissection of the cones shows they are an elongated ridge and not really a symmetrical cone. Biological cones are almost always very symmetrical. Rocks around the structures have been metamorphosed by heat and pressure. The recent conclusion of scientists studying stromatolites is that they are the product of metamorphic activity on volcanic material and are not biologic.

Not all of the experts in paleontology are willing to buy into the idea that a stromatolite results from tectonics and not biology. One of the reasons is that this would require an overhaul of the theoretical model for the development of life on planet Earth. The Bible simply says that the first life-forms God created were plants. The biblical sequence of plant formation in Genesis 1:12-13 was:

“deshe” meaning grass
Translated “grass” in KJV and “vegetation” in some newer translations.

“eseb” meaning naked seed or gymnosperm
Translated “herb” in the KJV and “plants bearing seed” in some newer translations.

“ets” meaning flowering tree or angiosperm
Translated “fruit tree” in KJV and “trees bearing fruit” in newer translations.

It will be interesting to see where the newest scientific controversy leads. But the lesson of history is that when science makes new discoveries and verifies them, they always support the biblical record if we take it literally. This appears to be one more example of that.

Learn from the Animals

Learn from the Animals
We are frequently astounded by what animals can do. As science seeks solutions to problems such as having enough food, knowing how to avoid disasters, and solving medical problems, we frequently see the answers in the designed features of living things. There are many things we can learn from the animals.

How can we have enough food to feed everyone on this planet? One way is to take advantage of animals with high reproductive capacity. A female mackerel, for example, lays about 500,000 eggs at one time. We have relied on animals like cattle which have one offspring at a time, are environmentally unfriendly, and require massive energy to sustain. Many fish, arthropods and mollusks can reproduce massive numbers of offspring, need very little energy input, and give off little or no environmental hazards. Some of them even remove environmentally unfriendly materials.

Can we improve our vision and perhaps restore sight to people who are blind? Studies of the common dragonfly have shown that each eye has 30,000 lenses. Our one lens is limited as to what we can see. The way images are transmitted to the brain in animals allows multiple transmissions. We are learning from insects and chameleons how the brain can reconstruct a useful image from many separate images. A chameleon can move its eyes in different directions, and its brain can interpret the direction and identification of what each eye is seeing independently.

How can we make stronger materials? Beaver’s teeth are so sharp that Native Americans used them as knife blades. The structure of the tooth enamel in the beaver and how the teeth maintain their sharpness is an area where materials science researchers can learn from the animals.

Can we make better drones? Researchers are interested in how high-frequency wing beats can allow better control of flight. Tiny flies known as midges beat their wings over 1000 times a second – twice as fast as mosquitoes. We can even learn from the animals that are almost too small to see.

Examples like these challenge those who would attribute animal design to chance processes and survival of the fittest. The design engineering in the animal world suggests wisdom beyond that of humans. In Proverbs 8:5,22,35 wisdom speaks, “O you simple ones understand wisdom and you foolish ones, have an understanding heart. The Lord possessed me (wisdom) in the beginning of His way, before His works of old. For whoever finds me finds life and shall obtain the favor of the Lord.” Let us be wise as we copy the wise designs of the Creator.

Alone In the Milky Way

Alone In the Milky Way
Yesterday we mentioned an article by John Gribbin in Scientific American (September 2018, page 96 or online HERE.) The title of the article was “Are Humans Alone in the Milky Way?” Although Gribbin suggests that some form of life exists elsewhere in the galaxy, he insists there could be no sentient beings like ourselves. The reasons for concluding that we are alone in the Milky Way galaxy are these “amazing” and “implausible” “coincidences.”

SPECIAL TIMING. The elements that make up a terrestrial planet like Earth are produced from hydrogen and helium by thermonuclear fusion. We see supernova explosions producing the heavy metals that make up a terrestrial planet and life itself, but it takes time for this process to create the necessary elements. Most of the exoplanets we see have minimal amounts of the heavy elements because they are early in their stellar evolution. Even the sun itself is 71% hydrogen and 27% helium with only 2% metals. The timing of putting the materials together to make a terrestrial planet is critical.

LOCATION IN THE GALAXY. The location of a solar system in the galaxy makes a difference. The galactic habitable zone is the area where there is a freedom from the concentration of supernovae. Systems near the center of the galaxy have high levels of radiation in the form of X-rays and cosmic rays. There is a massive black hole in the center of our galaxy called Sagittarius A which produces massive amounts of radiation. Gamma-ray bursts occur in certain places in the galaxy. In our area of the galaxy, sterilizing radiation bursts do not happen.

Recent studies of the galactic habitable zone tell us that it extends from 23,000 to 30,000 light-years from the center or only about 7% of the galactic radius. This zone contains only about 5% of the stars, because stars tend to concentrate toward the core of the galaxy. Our Sun is close to the center of the galactic habitable zone providing rare long-term stability.

TYPE OF PLANET. So far astronomers have discovered about 50 “earth-like planets.” What that means is that they have found rocky planets in the habitable zone that are about the same size as Earth. Venus would qualify as an “Earth-like planet,” but it is an excellent example of how misleading that statement is. Venus has a thick crust with no sign of plate tectonics, no magnetic field, no way to recycle materials, and no stabilizing moon. Our Moon keeps the tilt of Earth’s axis at 23 ½ degrees providing a stable climate.

Realize that all of these factors are just to have a ball of rock in the right place at the right time with the right materials with which to make life. Now we would need to calculate the odds of getting the right chemicals together at the right time in the right place with the right catalyst to make the first living thing. Books have been written about how improbable those steps are. The writers are not religious fanatics, but scientists who are doing the research.

The Scientific American article, concludes that we are alone in the Milky Way:

“As we put everything together, what can we say? Is life likely to exist elsewhere in the galaxy? Almost certainly yes, given the speed with which it appeared on Earth. Is another technological civilization likely to exist today? Almost certainly no, given the chain of circumstances that led to our existence. These considerations suggest we are unique not just on our planet but in the whole Milky Way. And if our planet is so special, it becomes all the more important to preserve this unique world for ourselves, our descendants and the many creatures that call Earth home.”

We must make one additional point. If an intelligent Creator was involved in this process, the probability of a habitable Earth with life on it is 100%. Perhaps we are not really alone in the Milky Way because there is a God who cares about us. For those who might want to consider this option, we encourage you to watch program #6 of the video series available free on doesgodexist.tv.

Implausible Coincidences

Implausible Coincidences in the Milky Way
Our ministry has been in existence for 50 years this month. During that time we have presented a large number of evidences that the creation of Earth and life on Earth cannot be a product of chance. Our arguments have been statistical, starting with the basic rule that when you have many parameters, you can estimate the total probability by multiplying the odds of all the factors involved. That approach has not changed, but the number of parameters and the odds grows with new data and information. Implausible coincidences continue to compound.

In the past several years, astronomers have found thousands of planets orbiting other stars in the Milky Way. Skeptics point out that the probability of one of those planets harboring sentient beings like ourselves gets better with each new discovery. Scientific American (September 2018, page 96) published a good review of some of the factors that are involved. The article plainly states this:

“Optimism about the possibilities of intelligent extraterrestrial life ignores what we know about how humans came to exist. We are here because of a long chain of implausible coincidences – many, many, many things had to go right to result on the situation in which we find ourselves. This chain is so implausible, in fact, that there is good reason to conclude that humans most likely are the only technological civilization in the galaxy.”

That is an interesting conclusion. The article goes on to list the variables that point to that conclusion:

SPECIAL TIMING
LOCATION IN THE GALAXY
TYPE OF PLANET

Tomorrow, we will examine those “coincidences.” The article concludes by describing the improbable nature of advanced human life. However, it credits evolution for the creation of that life while showing how “implausible” and “amazing” it is. We believe a supernatural Intelligence was involved which we call God.

Design In Nature

Design In Nature
When a person says that the mindless forces of evolution can easily explain everything that appears to be design in nature, you have to wonder if that person understands the principles of statistics.

From a statistical standpoint the more parameters that exist, the less likely it is that a desired final result will occur. The odds of a single coin flipped into the air and landing on heads is one in two or 1/2. What are the odds of five flipped coins landing heads up? That would be 1/2 multiplied by itself five times. The answer is one in thirty-two or 1/32. If you throw fifty coins up at the same time, the chance of all fifty showing heads is so small as to be considered impossible. (Multiply 1/2 fifty times.)

In nature, we see situations where the odds would be equivalent to throwing a million (or more) coins up and having them all land on heads. There is no way that an open-minded, thinking person can begin to entertain the idea that blind chance can explain such events.

Books and movies on nature often use a phrase like “nature planned…” or “evolution engineered…” or “genetic forces created…” some natural phenomenon. If you truly believe that the forces that created and designed the universe with our planet and everything on it are “mindless, blind, mechanistic chance,” then you can’t attach words that indicate wisdom, purpose, design, engineering, or creativity.

The design in nature is hard to miss. It has to be rooted in the mind of a Designer. Some things are just beyond what mere chance can do.

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.

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.
