Our Ancestor Was a Rat

Our Ancestor Was a Rat
The headline of a lead article in USA Today for November 8, 2017, said: “Our Ancestors Were Rats.” Written by Doyle Rice, the article claims that fossils prove our distant ancestor was a rat.

According to the article, Steve Sweetman of the University of Portsmouth in the U.K. says we know about this ancestor of ours. He said it is “undoubtedly the earliest yet known from a line of mammals that led to our own species.” The article further said that line of mammals included blue whales and pygmy shrews. Sweetman says the mammals they have discovered “were small furry creatures.” He speculates that they were nocturnal, possibly burrowers, and ate insects and possibly plants.

Would we not assume that this newly discovered fossil had a skeleton and traces or impressions of fur? Wouldn’t we have found coprolite (petrified poop) to make claims about what the animal’s diet was or perhaps plant or insect material in the animal’s stomach? Would we not also assume that the biosphere in which the animal lived was well documented by fossils of what the animal ate? Are we not assuming that the “line of mammals that led to our own species” has been so well documented that no reputable scientist would deny it?

The fact is that an undergraduate student was sifting through rocks and fossils in a box in his geology lab when he found two teeth which he showed to Sweetman who is a mammal expert. That is all the evidence we have for this rat which was supposedly our ancestor. How do you determine the animal had fur from two teeth?

There is great controversy about the phylogenetic trees that various scientists have constructed to develop theories about the history of life on planet Earth and human life. Many scientists believe that multiple trees and cladistic techniques better explain the history of life than the our ancestor was a rat version that Sweetman promotes.

We have said that when there is a conflict between faith in God and science, it is because of bad theology and/or bad science. Maybe bad journalism is another source of problems. This story is grossly misleading and represents the source of many of the conflicts that young people have between what they hear at Church and what they hear from the media.

Eating Blood: Is It Moral and Wise?

Eating Blood
We have received several questions about whether Christians should practice drinking or eating blood, eating afterbirth, or injecting or eating animal hormones. This goes back to Genesis 9:3-4 where God told Noah not to eat blood, and the prohibition about eating blood continues throughout the Old Testament (See Leviticus 17:10-11). In the New Testament, we see a prohibition about eating blood in Acts 15:20-29.

There are two different things involved here. One is the question of religious significance, and the other is what is hygienically wise. In the Old Testament blood was a major part of the daily religious life of the Israelites. To offer blood as a sacrifice for sin was to “give up life” for sin, and thus eating blood was a form of idolatry. It was like saying that God was not needed as the life giver and that the eater had power over life. In Acts 15:20 the restriction of not eating blood was included with “abstaining from the pollution of idols” for the reason of the connection to idolatry.

The hygienic issue of eating blood should be obvious. Any disease an animal had could be passed on through the animal’s blood. The warning against eating a thing strangled (Leviticus 17:13-16 and Acts 15:20) was because the blood remains in the flesh instead of being drained out as in the practice of butchering. When Paul wrote to the Christians in 1 Corinthians 10:23-33, he advised them when having a meal with an unbeliever, “…whatever is set before you, eat, asking no question.” But then he goes on to point out that Christians must be concerned about how their choices affect others.

In today’s world, we may have hygienic reasons for not eating something, but food prohibitions are not a part of the teachings of Jesus or His apostles.

Fire Ant Towers

Fire Ant Towers
Those who live in areas where fire ants are active can tell you about fire ant towers. The ants will encircle a rod, stick, or tree to build a tower that is wide at the base and narrows as it goes up. You can watch this behavior on a video posted here.

Researchers at the Georgia Institute of Technology were interested in how the ants do this without crushing the ants at the bottom. What they found was that the ants form rings around the structure at the center using their sticky feet to cling to each other. The rings are all concentric, but they get smaller as the tower grows. Ants near the bottom only stay there for a short time, backing off to take a break and then climbing up to the top to rejoin the structure to keep the tower standing. These towers are temporary, but they shield the colony from outside forces.

This behavior of fire ants cannot be learned. It is certainly not the product of trial and error but is clearly programmed into the ant’s DNA. Many insect behaviors are characteristic and peculiar to a certain species of insect. These built-in skills strongly suggest that the programming was done by an intelligent Creator to enhance the survival of the insects.

Proverbs 6:6 tells us, “Go to the ant, you sluggard; consider its ways and be wise.” While the passage is about being active in providing for the future and avoiding poverty, the message also comes to us today to see the handiwork of God in even His smallest creatures. Scientists are studying these ants to learn how they work together and build fire ant towers so that science can apply that intelligence to program robots.

Incredible Color

Incredible Color
Our ability to see the incredible color in the world around us is amazingly complex. We don’t actually see color with our eyes. We see color with our brains.

Most humans have trichromatic vision. Our eyes only detect red, green and blue. If our eyes detect a lot of red and green but not much blue, our brains decide that we are seeing yellow. When our eyes register equal amounts of red, green, and blue, our brain decides that we are seeing gray. If red and blue are present, but not much green, our brain decides we are seeing purple.

Some of us do not have red or green receptors in our eyes, especially people with XY chromosomes (males). We call it color blindness, but in reality, our eyes just don’t see one particular set of wavelengths. Some of us with XX chromosomes (females) may have tetrachromacy which means we see more than the three primary colors.

In the animal world, color is produced by many different techniques. The wings of the Morpho butterfly appear to be blue or violet depending on how the light strikes them. This is due to light-scattering scales that cover the insect’s wings. Dragonfly wings look similar to the Morpho wings, but the dragonfly’s color comes from waxy crystals that cover layers of the pigment melanin. We call the method of color production in these insects “structural color” because it is produced by the structure of the material rather than by pigments. Cameleons also use structural color using nanocrystals in their skin. They can tune the nanocrystals to reflect different colors. In this way, they can match the color of their environment or their mood.

We use color in many different ways such as camouflage, disguising foods to avoid their natural look, and to identify things. Much of the color that we see in the world has no practical value. For the most part, beauty is not a survival attribute. Evolutionary models attempt to explain some of the coloration we see around us, but in many cases, color is not a survival factor. Incredible color may be simply an expression of God’s desire for us to see the beauty and the majesty of His creation.

Most Sophisticated Visual System

Most Sophisticated Visual System
You might be surprised to know what animal has the most sophisticated visual system. Its eyes have at least twice as many types of color receptors compared to human eyes. They have three focal points while human eyes have only one. This animal can see both ultraviolet and infrared light, which our eyes cannot do. It has six polarization channels in each eye with high polarization sensitivity and hyperspectral imaging. What is the animal with this incredible visual system? It’s the mantis shrimp–a marine crustacean of the order Stomatopoda.

Researchers studying this animal’s eye say that it not only surpasses the sensitivity of our own visual system, but also captures more visual information, uses less power, and takes up less space than the most sophisticated state-of-the-art cameras. Scientists at the University of Illinois have developed a color-polarization camera based on the mantis shrimp’s visual system. The camera can aid in the early detection of cancer.

Mantis shrimps communicate using polarized light which cannot be detected by predators. They polarize the light by sending it across a reflector rather than the conventional method of sending the light through a lens. Researchers are copying this method of the mantis shrimp to develop a single chip, low-power, high-resolution color-polarization camera. The National Science Foundation and the Air Force Office of Scientific Research are sponsoring the project. The mantis-copied camera concept has great potential for a variety of applications.

Romans 1:19-20 tells us we can know there is a God through the things He has made. Again and again, scientists discover design’s like the most sophisticated visual system of the mantis shrimp. These amazing discoveries happen in every discipline of science. It is an exciting time to be alive, as we see more and more examples of God’s creative wisdom and design.

Cormorants Find Fish in Muddy Waters

Cormorants Find Fish in Muddy Waters
Several years ago a flock of cormorants arrived on the St. Joseph River near our home. The river was close to flood stage. The water was so muddy that you couldn’t see the bottom even if the water had been only an inch deep. Those birds demonstrated that cormorants find fish in muddy waters.

The birds landed in a large tree on an island in the middle of the river. Very soon after they landed, one took off and dove into the river. A minute or so later it came to the surface with a fish in its beak. For the rest of the day, we saw these fishing birds dive and catch fish, sometimes staying under water for a very long time. I wondered how they could do that because sight in the water was non-existent.

In the October/November 2017, issue of National Wildlife (page 8), there is an article explaining how cormorants and other fish-eating birds manage when the water is so loaded with mud that they can’t see. Scientists at the University of Southern Denmark have studied the hearing of the great cormorant. They discovered that this seabird has a specialized sense of hearing tuned to a very narrow frequency range. The frequency is the same as the sound produced by herring and sculpin fish as they swim in the water. Those fish are the primary prey of the cormorant and sculpin live on the bottom of water bodies where it is dark, and the water is often dirty.

There are over 800 species of birds that find their food underwater. Since these cormorants find fish in muddy waters, the scientists on this project predict that other aquatic birds also use specialized hearing to catch fish. We see this as another design that God gave these creatures for survival.

Lesson from the Bees

Lesson from the Bees
For a bee to fill its honey stomach with nectar to take back to the colony, it has to visit from 100 to 1500 flowers. The honey stomach is a special pouch for the nectar, and it can hold about 70 mg (0.0025 oz). To make one pound (.454 kg) of honey requires 50,000 bee-loads of nectar. You might think that this is a very inefficient and poorly designed system. However, we can learn a lesson from the bees.

Every year beekeepers in the United States collect about 163 million pounds (74 million kg) of honey. Besides that, each bee colony will eat between 120 and 200 pounds (54 to 90 kg) of its own honey in a year. The bee’s system for producing honey is highly efficient, and well coordinated in the hive. How is that possible?

Two things make honey production productive. There are enormous numbers of bees, and they all work together. Each bee contributes a very small amount, and each one has a job to do. The hive contains many bees with one purpose, goal, and objective—to make the hive work. They are each 100% committed to the purpose of getting the job done. There is no squabbling, no power politics, no division, and no jealousy among the bees.

We can learn a lesson from the bees. When Jesus told His followers to preach the gospel to every creature, He didn’t tell them something that was impossible to do. He also prayed for unity. He knew that division was the one thing that would stop His followers from getting the job done.

In Chapter 12 of 1 Corinthians, Paul wrote about the body of Christ, His Church. He said that “we were all baptized by one Spirit so as to form one body” even though we are diverse in our race and status. Then in verses 24-25 he adds, “But God has put the body together, giving greater honor to the parts that lacked it, so that there should be no division in the body, but that its parts should have equal concern for each other.”

Think of the different status and abilities of the bees in a hive working together for a common cause and learn a lesson from the bees.

Saharan Silver Ants

Saharan Silver Ants
The survival of living things in extreme conditions is always fascinating. There are places on Earth, such as the Sahara Desert, where the temperature on the ground can soar to 120 degrees Fahrenheit. Even in that extreme heat there are living things functioning very well in conditions that would be lethal to most forms of life.

Extreme survival is a way of life for the Saharan silver ants (Cataglyphis bombycina). The predators of these ants are desert lizards that retreat into their burrows in the heat of the day. Some of the ants keep watch to let the others know when the lizards are gone. Then the ant colony makes its food-search expedition. They come out into the full Sun and intense heat to scavenge animal carcasses. The picture shows them devouring an engorged camel tick.

The question is, “How do they survive the heat?” They have longer legs than most ants, and that keeps their bodies farther from the hot sand. They also travel across the sand at high speed (2.3 feet or 0.7 meters per second) using only four of their six legs to keep fewer feet on the ground. Also, their bodies produce heat-shock proteins that help their cells cope with the stress of the high temperature. Many animals produce heat-shock proteins, but not until they are exposed to extreme heat. The Saharan silver ants are programmed to produce those proteins before heat exposure to prepare them for what’s ahead.

Even with those adaptations, they are still exposed to the direct rays of the Sun. Scientists used electron microscopes to find the secret of the Saharan silver ant’s survival. The ants are covered with microscopic hairs that are not round or oval in cross-section like most hairs. They have a triangle shape to act as prisms. This shape reflects both the visible and infrared (heat) energy from the Sun away from their bodies. Because of these tiny prisms, the ants display a metallic shine. They look like metallic beads rolling quickly over the desert sand. No other desert creature has this form of reflection. Saharan silver ants are among the most heat-resistant creatures in the world.

Like many things in nature, engineers are looking into how we can imitate the prism method of these ants to protect humans from the dangers of extreme heat. Designing something that can reflect the heat this efficiently requires a deep understanding of optics and the nature of light and heat energy. The wisdom of the Creator shines brightly in the reflected light coming from the Saharan silver ants.

Lesson from the Unicorn

Lesson from the Unicorn
Do you believe that there was an animal in biblical days that looked like a horse with a huge horn? In ancient times people believed that such animals existed and that they had extraordinary powers. People in ancient times found horn-shaped fossils that were sometimes several feet long and believed that they were the remains of unicorns. Of course, they were wrong, but we can learn a lesson from the unicorn.

Science proved that unicorns did not exist, and the horns came from animals like the narwhal or ancient snails. So why are unicorns mentioned in the Bible? Is this evidence that much of the biblical record is simply a repeat of local legends and stories?

We can learn more than one lesson from the unicorn and the biblical record. The first lesson is that we must be very careful about translations. The King James translation of the Bible mentions unicorns in Numbers 23:22; Deuteronomy 33:17; Job 39:9-12; Isaiah 34:7; and Psalms 22:21, 29:6, and 92:10. At the time of the King James translation, there were many myths and stories about unicorns, and scientific facts were not available to assist Bible translators.

In the past, we have mentioned errors and language issues in the King James translation. Genesis 6 is an example, where the Hebrew word nephilim was translated “giant,” leaving major misunderstandings of what the text means. This part of the Genesis account was not translated directly from the Hebrew. It was translated from the Latin Vulgate translation. The Catholic translators of the Vulgate translated nephilim into the Latin gigantus. The King James translators didn’t know what to do with gigantus, so they just left it as “giant.” Nephilim actually means “fallen ones” and referred to humans who rejected God and His will. In the same way “unicorn” came from the Hebrew reem which means a “roaring animal” or a “wild ox.”

The primary message here is not to rely on a translation that is from many centuries in the past. Word meanings change and what a word means now can be radically different than what it meant in the past. Think about how the word “gay” has changed in its meaning in the past 50 years.

Another major lesson from the unicorn is to take the Bible literally. That means to look at who wrote the passage, to whom it was written, why it was written, and how the people it was written to would have understood it. In the biblical use of the word reem, the context makes it clear that it is describing a violent wild animal. None of the cases would refer to a magic horse-like animal.

When we say the Bible is inspired, we mean that it is accurate in all that it teaches, and we can understand it. Sometimes we have to do word studies to answer the challenges of skeptics and critics, and that is another lesson from the unicorn.

Butterfly Point of View

A Butterfly Point of View
Perhaps it would be good to see the world from a butterfly point of view. One of the wonders of the insect world is the emergence of a butterfly from a cocoon. The transformation that takes place is truly amazing as the caterpillar’ body is dissolved and reorganized into a butterfly. I remember as a kid cutting open a cocoon to see the developing butterfly and finding a gooey mass of green slime instead.

The wonder of butterflies can inspire our imagination. Someone named Margy wrote the following on February 27, 1990. Somehow this short poem found its way to me. It is a butterfly point of view of metamorphosis if a butterfly could think like a human. It’s also a reminder of how God can reshape us into something new.

In the fall, I enjoy the fresh air and falling leaves for the last time,
for soon I prepare a cocoon for myself.
A cocoon that will keep me safe and warm against the harsh winter!
I withdraw into the cocoon when it’s time, withdrawing into the darkness, away from the cold stings of the world.
I sleep and sleep, losing all energy, lying dormant.
It’s cloudy and dark. I feel the emptiness, loneliness.
I wait and wait!
And, when it’s time, God’s gentle voice tells me, “Wake up, you’re free!”
Slowly, I eat away at the cocoon, feeling the warmth of the sunshine on my face.
I step out, realizing God has blessed me with wings!
I’m anxious, but I make my first attempts to fly.
The wind helps lift me up into the gentle breeze.
I flap my wings. I’m flying! I’m free!
Once again I feel confident, confident to face the world.
