Otzi Had Dark Skin

Otzi Had Dark Skin
Otzi the Iceman

“Otzi” was the name given to a frozen mummy found on the border between Austria and Italy in 1991. The mummy, also known as “the iceman,” was in such good condition that researchers could complete a DNA analysis of his genome in 2012. Recently, more advanced studies of that DNA show that the earlier sample was contaminated by modern DNA, and Otzi had dark skin.

The Planck Institute for Evolutionary Anthropology in Leipzig, Germany, compiled a new genome for Otzi. Johannes Krause, writing for the Institute in the August 16, 2023, issue of “Cell Genomics,” reported that there is no connection between Otzi and modern residents of Austria or Italy. The revised genome shows that Otzi had dark skin and was related to Neolithic farmers.

Modern genomes of ancient humans show that dark skin has been the norm for humans until relatively recently in human history. Light skin tones only appeared in the genomes 3 to 4,000 years ago, showing once again the foolishness of racism. The ancient humans described in the Old Testament were undoubtedly dark-skinned.

You cannot use the Bible to justify racial prejudice. The statement that God “has made of one blood all nations of men to dwell upon the face of the earth” (Acts 17:26) is absolutely true. The name “Eve” in the Hebrew of Genesis means “life-giving,” and she would have had dark skin. Genetic studies have shown that all humans have a common DNA fragment indicating a common origin. Those who have viewed Otzi as proof that ancient humans were Caucasians have no scientific support for that claim and now have to admit that Otzi had dark skin.

There is too much scientific support for the biblical account of early humans to write it off as a fantasy or a myth. Science and the Christian faith are symbiotic – they support each other. Let us put racial prejudice to rest and embrace the claim of Galatians 3:28 that we “are all one.”

This Fish Sees With Its Skin

This Fish Sees With Its Skin
Hogfish

The many unique characteristics we see in animals enabling them to survive give evidence of God’s design and planning. Romans 1:20 says, “We can know there is a God through the things He has made.” Our daily posts here and on Facebook, as well as our Dandy Designs book series, show hundreds of examples. A new example is the hogfish (Lachnolaimus maximus) living in the Atlantic Ocean reefs from the Carolinas to Brazil. You can almost say this fish sees with its skin.

Like many animals, the hogfish’s primary method of survival is camouflage. They hide by changing colors and altering skin patterns. Many animals, such as chameleons, squid, and cuttlefish, have chromatophores, which are pigment-bearing cells that can change color to match the environment. Hogfish also use chromatophores in their skin to change colors, but they have a layer of opsin, a light-sensing protein, under the chromatophore layer.

The hogfish moves through different kinds of background material as the reef has quite varied colors and textures with corals, sponges, and sediment. The fish can change its color to match the environment, but it can’t turn its head to see what color it is. The opsin layer acts as a primitive eye looking at the chromatophores to see that the color matches the surroundings. In that way, this fish sees with its skin.

The design of fish survival in a reef involves a wide variety of techniques. Some can swim rapidly, some can bury themselves in the bottom sediment, and others have immunity to stinging organisms. There are fish who can fly (glide), some can swim in schools, and some, like the Hogfish, can camouflage themselves. Together, they make the reef a place full of life and beauty. Perhaps that beauty will encourage humans to preserve the reefs of the world as places of great aesthetic worth.

Children Seeking Gender Reassignment

Children Seeking Gender Reassignment

One of the most serious problems facing parents, schools, and churches is what to do with children seeking gender reassignment. This has become a political football, a money-making enterprise, a lawyer’s paradise, and a parent’s nightmare. Teachers deal with kids who are wearing several names and pronouns depending on what their day-to-day feelings dictate.

Those who promote gender reassignment confront unwilling parents with questions such as, “Do you want a dead daughter or a live son?” Studies show that the number of teenage girls with gender dysphoria has risen by 5,000% in seven years. This has become a massive money-maker for various groups, from Planned Parenthood to doctors and hospitals. 

A British book by Hannah Barnes titled Time to Think provides a wealth of data on this issue in Europe, and it’s getting some attention in the United States. Here are some interesting facts from Barnes’ book:

*A large number of children seeking gender reassignment had other psychological issues. In one study, 97.5% had one or more disturbing issues, including having been in foster care, endured parental divorce or death, been abused, or endured personal trauma. Seventy percent had five or more difficulties of this kind. Twenty-five percent had histories of self-harm. 

*Information given to children about sex change has been generally inaccurate. Kids have been told that puberty blockers would not affect bones, muscles, and brains or that effects were completely reversible. None of those assertions are true.

*Studies done since 2011 on the effects of puberty blockers in England showed no improvement in patients’ mental state. Sweden, Norway, and Finland have severely curtailed the use of puberty blockers and cross-sex hormones, saying that the risks outweigh the benefits.

There is a strong name-calling campaign against anyone who questions sex change. “Transphobic” has joined “homophobic” in the vocabulary of promoters of sex-change medications and surgical procedures. We are facing an uphill battle because greed and money are involved. The disintegration of God’s plan for the family and the selfishness and greed of adults have resulted in the use of children to satisfy adult issues. Working on children’s psychological problems is far better than throwing drugs and surgery at the needs of disturbed kids.

Birds Use Spikes to Protect Their Nests

Birds Use Spikes to Protect Their Nests - Eurasian Magpie
Eurasian Magpie

One of the exciting examples of design in the living world is the nesting behavior of birds. We have previously reported on data about birds that nest in peculiar places to protect their eggs and their behavior to thwart predators. We have all seen birds building nests in cliffs or under roof structures, but predatory birds like eagles and hawks can still land on the nests and eat the eggs or baby birds. Scientists have discovered that some birds use spikes to protect their nests from even bird predators.

Researchers in Belgium, the Netherlands, and Scotland found nests in which birds have used long spikes to make it difficult for predators to get to their eggs or chicks. One crow’s nest in Antwerp, Belgium, had 1500 long, sharp spikes. They would make reaching the nest’s occupants extremely difficult for any hawk or eagle. It would also deter other predators, such as cats.

The nests of carrion crows and Eurasian magpies have been found with spike defenses. These birds have used whatever sharp objects they can find in urban areas to build their fortress, including plastic pieces, nails, screws, and knitting needles.

Birds use spikes to protect their nests because God has built into the DNA of various bird species the ability to do unique things to survive. The more we learn about the natural world, the more we should be amazed at the intelligence and design behind all kinds of life on Earth. “We can know there is a God through the things He has made (Romans 1:20).

Preparing for Winter – How Do They Know?

Preparing for Winter – How Do Living Things Know?

The ability of plants and animals to achieve maximum survival success in changing seasons is quite interesting. Here in Michigan, our winters can arrive suddenly and forcefully. It may be 75 degrees one day and below freezing the next. It was quite warm in early September, but many trees were already preparing for winter. The leaves of our sumac trees became brilliant red and started falling off the branches. As we approach the end of September, some species of maple trees are changing colors and dropping their leaves.

Several species of birds have left Michigan, heading south for the winter. We live on a river where we see a massive increase in fish activity. There is also a significant increase in the activity of insects, with some butterflies, such as monarchs, heading south in groups. The number of cocoons in our bushes and in our house has accelerated, and some species of bees and wasps have become more aggressive.

The big question is how living things seem to know it’s time to start preparing for winter, even when there is no significant temperature change. There have also been no clues from other weather factors like humidity, rainfall, wind velocity, and direction. The scientific evidence shows that living things pick up on less obvious signals that say, “Winter is coming, and you need to prepare.”

Some living things sense the length of daylight, telling them to prepare for winter. Another factor is the angle of the Sun’s rays, which controls what kind of light reaches Earth’s surface. The Sun’s light contains a variety of wavelengths. The higher energy wavelengths are refracted and scattered more than the longer, lower energy forms. The sky is blue because blue light has higher energy than the rest of the visible spectrum and thus is scattered and refracted more. The next highest energy wavelength is green. Plants are green because they reflect that color, protecting them from the next highest energy of light that reaches Earth’s surface.

As the Sun gets lower in the sky, wavelengths we can’t even see, such as ultraviolet, are refracted and scattered away from the surface. Living things detect that change and start preparation for winter. Explaining how this system of life came into existence is a real challenge for those who deny God’s creation of our planet and the life on it. It’s a joy to see the things God has made testifying about His intelligence and design as they start preparing for winter (Romans 1:20).

Honey Buzzard Migration

Honey Buzzard Migration
European Honey Buzzard (Pernis apivorus)

The more we learn about bird and insect migrations, the more we are astounded by how they do what they do. Chance explanations fail when the migrations become complex. The honey buzzard migration is another example of an incredible migration that defies chance explanation.

Researchers using a satellite tracking system in Finland released data on a bird known as the European honey buzzard. This bird actually does eat honey and will search out the nest of bees and hornets to find its food. Scientists knew that this bird spends its austral summer around the town of Reitz in Free State, South Africa, where bee nests are abundant. They tracked the honey buzzard migration as it left Africa on April 20th and arrived in Finland on June 2nd at the time when, once again, its favorite food was available. This bird enjoys summer twice by its migration, securing food and avoiding winter, but its route is very complicated.

You might think the honey buzzard would just head north, but that would involve going over dangerous landforms and climate irregularities. Instead, the bird makes a 90-degree turn at the source of the Nile River and follows it. When the bird reaches the end of the Nile, it returns to the same longitude line where it started, avoiding the Mediterranean and the Sudan to eventually reach its destination in Finland.

Honey buzzards cover 10,000 kilometers in 42 days, averaging 230 kilometers daily. If you want to see honey buzzards attacking a bee nest, do a word search on the web, but don’t expect an explanation of its migratory route. The honey buzzard migration is programmed into the bird’s DNA, and how the program got there is another example of design by intelligence. Instinctive drives defy chance explanations because they involve a changing Earth with landforms and climate factors that happen too fast for gradual accommodation. We suggest that honey buzzard migration is another evidence of God’s design for all life forms in the creation.

North American Curly Horses and Evolution

North American Curly Horses

One of the great tragedies of the evolution/creation war has been the failure of people on all sides to define what they mean by “evolution.” We see a classic example in North American Curly Horses, sometimes called the American Bashkir Curly. This breed of horses has a heavily curled coat in the winter, and a much thinner coat in summer, when the mane and tail molt.

The curly coat is an advantage during very cold weather. In addition to the unusual coat, North American Curly Horses are well known for various other characteristics. They are much quieter in disposition than other horses and have thicker bones, rounded hooves, and exceptional memory. Curly horses are the only hypoallergenic horse breed – good news for people allergic to horses.

Horses can be traced back to the time when their ancestor was a small creature about the size of a dog. The best-known fossil horse is eohippus, sometimes called the “dawn horse,” but other forms of horses based on fossilized remains are merychippus, mesohippus, and miohippus. North American Curly Horses are hypoallergenic because a protein that most horse-allergic people react to is absent from their hair. Horse ranchers are cross-breeding curly horses with other breeds to establish some of their characteristics in other breeds.

North American Curly Horses are another example of how humans have benefited from evolutionary change. This evolution is not part of a theory to deny God as the creator. The design of life that allows change in this way is an excellent testimony to the wisdom and intelligence of God’s creation. When God created the first horse, He built into its DNA the genes that would allow change. We can say the same of the many other plants and animals humans need to survive on this planet.

Evolution of species is an excellent proof of the existence of God, but don’t confuse it with creation. They deal with two different things. Creation produced the first horse-like animals, and God’s design of life allowed them to change into the North American Curly Horses and other breeds we have today.

An Octopus Garden

One of the more interesting creatures in the ocean is a small octopus called the pearl octopus (Muusoctopus robustus). They get their name because they look like pearls on the dark ocean floor. Because of their small size, they are easy victims of predation. They have no defense mechanisms and are an easy meal for various predatory ocean creatures. How do they continue to thrive in their Pacific Ocean habitat? The answer lies in an octopus garden.

Researchers discovered the octopus garden 80 miles from the central California coast at a place called the Davidson Seamount. A seamount is an ancient volcano that has either sunk into the ocean floor or has been covered by rising ocean water. The Monterey National Marine Sanctuary and Monterey Bay Aquarium Research Institute have studied deep-sea corals on this seamount for 20 years. They recently discovered an octopus garden – home to at least 6,000 nesting pearl octopuses and perhaps as many as 20,000.

The design of this “garden” offers successful reproduction of this vulnerable species. By being 10,500 feet down, they avoid many octopus predators simply because they don’t feed that deep. Like many other forms of life, synchronized birthing floods the area with offspring so a predator can’t wipe out a whole population. Hydrothermal springs at the base of Davidson Seamount warm the water, allowing the pearl octopus eggs to hatch much faster.

We see many remarkable designs in the biological world, allowing animals to survive. Every nook and cranny of the planet is home to some form of life, and this is just one more example. As Romans 1:20 says, “We can know there is a God through the things He has made.”

Siphonophores – A Colony of Animals Living as One

Siphonophores – A Colony of Animals Living as One
Portuguese Man O’ War

The more science learns about the biological world, the more unique things we see. Most of us know about jellyfish, corals, and anemones. These ocean animals are members of the phylum Cnidaria. In that phylum, a strange order named Siphonophorae has 175 species. The Portuguese man o’ war is a member of the order of siphonophores.

Siphonophores may look like one organism, but they are actually colonies consisting of thousands of clones that function in different ways. Siphonophores start with a single “bud” called a zooid. The zooid replicates itself asexually, producing thousands of clones. Each clone has a specific job, such as eating, moving, or reproducing. 

The colony of clones functions together as if they were one animal. For example, the Portuguese man o’ war has gas-filled zooids, allowing it to float on the ocean’s surface. Other zooids capture prey, while others digest the food. The individual zooids rely on each other for survival as one large functioning colony we call the Portuguese man o’ war.

In 2020, scientists found a siphonophore that was 150 feet long, probably the world’s longest animal. Most siphonophores live in the darkness of the deep oceans and are bioluminescent, using chemicals to produce light that attracts prey. The Portuguese man o’ war is an exception as a siphonophore that lives on the ocean’s surface. 

The deep sea diving expeditions of the Schmidt Ocean Institute and the EV Nautilus have taught us much about the designs built into living things that allow life to exist in places totally alien to humans. Siphonophores make us realize that planet Earth is a wonderfully designed and unique place in the universe, full of amazing living creatures. We must treasure God’s gift and take care of it instead of abusing and polluting it.

The Thymus and Adult Health

The Thymus and Adult Health

New research shows a connection between the thymus and adult health. When I was a child in the early 1940s, doctors performed surgeries on children to remove a gland or organ because they thought it was vestigial and no longer needed. By the time I was in high school, my tonsils, adenoids, and appendix had all been removed. When my daughter Wendy became a teenager, she had repeated throat issues and infections. Her doctor refused to remove her tonsils or adenoids even though they were infected and hurting her repeatedly.

We know now that the tonsils and adenoids are an important part of the lymphatic system, keeping our bodies healthy by trapping harmful bacteria and viruses. As we have come to understand the immune system in humans, we have found that surgically removing the tonsils and adenoids can open us to infections. New research indicates the same is true of the thymus.

The thymus is a gland in the chest between the lungs, in front of and above the heart. It produces immune cells called T cells that protect against foreign invaders that could cause illness. In children, the thymus is very active, but after puberty, it shrinks. By then, the body has memory T cells specialized in attacking intruders the body has fought before. Since the thymus gradually becomes smaller, it is frequently removed in heart operations because it gets in the way.

Oncologist David Scadden and colleagues at Massachusetts General Hospital in Boston researched the thymus and adult health. They examined the health outcomes of 1,146 patients who had their thymus removed at the hospital between 1993 and 2020. They compared those with an equal number of patients who had the same surgeries but did not have their thymus removed. The death rate for those whose thymus was removed was three times higher than those who did not. Thymus removal was also associated with two times the risk of cancer within five years.

The thymus serves a purpose in childhood but may play a different role in adulthood. The researchers don’t know the cause of these striking numbers, but they show a strong connection between the thymus and adult health. We now know that the appendix, tonsils, and adenoids contribute to the body’s immune system to help keep us healthy. It appears that we should add the thymus to that list.

Psalms 139:14 says, “I will praise you, God, for I am fearfully and wonderfully made: marvelous are your works..” We don’t have to look far to see God’s wisdom and design in creation. Just look in the mirror.
