California Condor Parthenogenesis

In the 1980s, there was great concern about the shrinking population of California condors. In 1987, they became extinct in the wild, and only 22 were left in captivity. Due to a captive breeding program, at last count, there were 518 living California Condors in 2019. Most of them were in the wild in California, Arizona, and Utah. Recently, scientists discovered two cases of California condor parthenogenesis, or as news reports called it, “virgin birth.”

Researchers from the San Diego Wildlife Alliance discovered two male condors who had not been produced by sexual reproduction, even though their mothers had previously produced offspring in the usual way. The scientists could determine that because they have a record of the genetic data for the more than 900 condors hatched since the captive breeding program began in the 1980s. Both birds contained identical copies of their mother’s DNA, which cannot happen when a female’s egg has been fertilized by sperm.

Parthenogenesis occurs in some insects and other invertebrates and a few fish, amphibian, and reptile species. It even happens in some captive birds, but it is unknown in wild birds. I have often kidded my biologist friends about their discipline, saying that the only universal rule in biology is that anything you say always has an exception. California condor parthenogenesis is one of those exceptions.

Reasons for preserving wildlife are to protect the environment and its impact on humans and learn from studying the design of living things. But, of course, another reason is to enjoy the beauty of the natural world. We can see God’s creative wisdom in the world all around us, and the more we know about the creation, the better we understand the Creator.

Life Under the Antarctic Ice Shelf

One of the amazing things about our planet is its ability to support life. We find a diversity of living things on land, in the air, and under the oceans. Scientists have even found a variety of life under the Antarctic Ice Shelf.

Gerhard Kuhn and Raphael Gromig of Germany’s Alfred Wegener Institute, a polar and marine research organization, drilled through the Antarctic ice shelf. After boring through 656 feet (200 m) of ice, they scooped up material from the seafloor another 328 feet (100 m) down. What they brought up surprised them. They turned the material over to David Barnes, a marine biologist with the British Antarctic Survey. He was so amazed that he said, “Is this a practical joke?”

Barnes was surprised that as he studied the sediment, he identified 77 different species of animal life in the material they extracted from a single drill hole. The species identified included bryozoans, which are stationary filter feeders, and tube-feeding worms. Barnes said, “This discovery of so much life living in these extreme conditions is a complete surprise…”

Filter-feeders feed on algae which require sunlight to grow. However, there is no sunlight to provide photosynthetic life under the Antarctic ice shelf. The explanation is that these creatures are feasting on microorganisms that the ocean currents sweep under the ice shelf. You could say the food is delivered to their doorstep.

Despite the cold and dark conditions, life survives in a location where fires, storms, or predators do not threaten it. The only thing that may threaten these creatures is the melting and breakup of the ice shelves. So, here in one of Earth’s least-known habitats, life survives. Like the scientists who discovered and studied these life forms, we are amazed. But, more than that, we thank God for wisely creating life with the ability to adapt and survive even in hostile environments.

Animal Tool Use and What It Means

An interesting fact about animals is their ability to use tools. Years ago, people thought that only humans used tools, but recent studies have shown animal tool use. However, the word “tool” means different things to different people.

Webster defines a tool as “an instrument used to accomplish a given task.” By that definition, we can find examples of animal tool use. We have reported on some of them before. For example, HERE and HERE.

Science News reported that polar bears sometimes kill walrus by bashing them with chunks of stone or ice. People have observed birds cracking nuts by dropping them from high altitudes onto rocks. Elephants use tree trunks for a variety of purposes, and crows use sticks to pry off the lids of bottles. Chimpanzees use conchoidally fractured chert or flint to cut open a fruit. Those of us who have bird feeders have seen squirrels use a tree branch to access a feeder. Recently, researchers in Israel taught fish how to drive a “car.”

There is a difference between a tool and a machine. According to the dictionary, a machine is “an assembly of interconnected components arranged to transmit or modify force in order to perform useful work.” A broader question here is whether intelligence is needed to fashion a machine? If that is the case, intelligent animals should be making machines, and mentally challenged humans would not be able to do so.

This discussion of animal tool use gets into difficulties because the anatomical parts of all animals are simple machines. Limbs are levers, and teeth are wedges. The design of all animals includes the equipment to secure food and shelter. Building into animals the ability to use objects in their environment to survive is another example of God’s design in the natural world.

Studies indicate incredible wisdom and planning in the creation of animal life. However, what sets humans apart from all other animals is not tools, machines, or intelligence. Instead, our spiritual nature is what makes humans different.

The ability of humans to create art, express ourselves in music, conceive of self, worship, and be taught to think set humans apart. To have an agape type of love that is not sexual and does not promote survival makes us human. The mentally challenged among us possess these abilities because all of us are created in the image of God. Animal tool use is far removed from possessing God’s image.

Evolution Is Not Creation

An error shared by some creationists and some evolutionists is confusing evolution with creation. One problem is that the terms “creation” and “evolution” do not mean the same thing to different people. Regardless of how we use the terms, evolution is not creation. Evolution and creation are two completely different subjects that are only very remotely related.

We see the concept of creation in the very first verse of Genesis 1. “Reshith Elohim bara shamayim erets” is the Hebrew of this verse. Each of these words has great significance:

“Reshith” tells us that there was a beginning to time, space, and matter-energy. Our studies in quantum physics continue to support that statement.

“Elohim” is a plural word for God and conveys the power and nature of the agent that produced the beginning.

“Bara” is a word used only in reference to God and implies a process beyond human capacity to reproduce.

“Shamayim” refers to “heaved up things,” meaning the expanding universe.

“Erets” refers to our functional planet. It is used 648 times in the Old Testament.

A person might deny God as the causal agent of time, space, and matter-energy. Nevertheless, the creation’s characteristics strongly suggest intelligence and wisdom. However, this entire subject has very little to do with evolution. “Evolution” means “unfolding change.” The evolutionist starts with the assumption that not only time, space, and matter-energy existed, but that they existed in a form that allowed change to take place.

Many evolutionary scientists bring into their thinking the question of God’s role in shaping what He had already created. The other option is naturalistic evolution which attributes all we see in the natural world to chance. But, regardless of how you define the terms, realize that evolution is not creation.

For some interesting points on this topic from the perspective of a scientist who is a Christian, we suggest “How might God have Guided Evolution? Scientific and Theological Viewpoints” by Dr. Peter Bussey. It was published in the June 2021 issue of the Journal of the American Scientific Affiliation. Dr. Bussey is Emeritus Reader in Physics with the University of Glasgow in Scotland and works with the European Organization for Nuclear Research (CERN) and its Large Hadron Collider (LHC), the world’s largest particle accelerator.

A Larger Dinosaur Has Been Found

We are amazed by the enormous size of animals in the distant past. From a giant millipede to the Titanoboa and the Titanosaur, the size of ancient animals excites fossil hunters. Since 2017, Patagotitan has held the record for the largest dinosaur at 120 feet (36.5 m) long and weighing over 57 tons. However, paleontologists in Argentina recently found pieces of a larger dinosaur.

The size of this animal has several implications. First, we need to be reminded that, unlike mammals, reptiles never stop growing, so there is virtually no limit to their size. A more significant issue is having environments warm enough for such animals to live and enough plant material to sustain them, plus a high oxygen level.

The environment that allowed a larger dinosaur to survive would not have been hospitable to mammals. Reptiles can not only survive very hot conditions, but they require heat to sustain their bulk. A hot Earth with very wet conditions would also promote rapid plant growth. Accordingly, the plant fossils from the time of those animals indicate huge size and rapid growth.

The Bible makes clear that everything humans would need to live on Earth was produced before humans were created. Therefore, we have maintained that God was not a magician miraculously zapping things into existence. God could do the creation any way He wished, but He wisely chose to make the resources humans would need in such a way that we could find them.

God acted as an engineer, producing the coal, gas, oil, iron, salt, and other resources we would need by processes we can study and understand. The volume of fossil fuels stored up for our use is a staggering number. Present-day processes on Earth could never produce them, but the enormous animals and plants of the past created enough resources to take us into the nuclear/solar age.

The Bible tells us that God created planet Earth, not how or how long He took to do it. Genesis 1:1 is not dated or timed. However, as we look at the record of the past, we see God’s wisdom and power and the magnitude of the creative process that allows us to exist.

Rather than trying to fit a larger dinosaur into Noah’s Ark, we need to take Genesis for what it says and not add denominational traditions. We must not use the economy of language in Genesis to justify our human religious theories.

Edward O Wilson Was an Authority on Ants

You may recognize the name Edward O. Wilson whom evolutionists associate with sociobiology. However, the Harvard biologist who passed away in December at the age of 92 was actually more famous for his detailed study of ants. There are currently over 15,000 known species of ants, with probably thousands more, and Edward O Wilson was an authority on ants.

Wilson’s studies included ants that can walk under water to find dead insects or glide from one tree to another or join together to make a raft to carry their queen and eggs to safety away from a flooded nest. Wilson pointed out the complex social organization of an ant colony. He wrote that “Karl Marx was right, socialism works, it is just that he had the wrong species.”

Wilson summarized his work by saying, “Our sense of wonder grows exponentially: the greater the knowledge, the deeper the mystery and the more we seek knowledge to create new mystery.” Proverbs 6:6 gives a similar message: “Go to the ant, thou sluggard; consider her ways and be wise.” We have considered the ways of ants many times on this website and in our printed journal. You can find links to some of those articles below.

Edward O Wilson was an authority on ants, and although we disagree with his agnosticism and materialistic Darwinism, we applaud him for giving us information about the world of ants. His work reinforces the message of Romans 1:20 that “we can know there is a God through the things He has made.”

A Giant Millipede and What It Teaches Us

Can you imagine a giant millipede almost nine feet long? Most of us have seen inch-long millipedes under a rock or in a rotting log. Like centipedes, millipedes get their name from their many legs. “Mille” means thousand, and “ped” means foot, so a millipede could have a thousand feet.

Some 10,000 species of millipedes live today, and they are related to lobsters, shrimp, and crayfish. Australian researchers recently announced finding a three-inch-long millipede with 1,306 legs, which stirred up great interest among biologists. But that is nothing compared to a new fossil discovery.

Now researchers from the University of Cambridge have found the fossil of a true giant millipede in England. This specimen is 8.6 feet long and would have weighed about 110 pounds. Named Arthropleura, this is the largest invertebrate ever found, replacing giant sea scorpions that previously held the record. This animal lived before the dinosaurs and was an omnivore eating plants, nuts, seeds, and other invertebrates.

The importance of a find like this giant millipede is that it tells us that large animals, insects, and plants existed in the past. In addition, it reminds us that the ecology of the early Earth, as it was being prepared for later life forms, was very different from what we see today. At that time, England was a tropical area where massive quantities of resources like coal, limestone, and various minerals were being produced. Therefore, the plant and animal life in that ecology had to be large.

The Bible does not describe all of the processes because even today, we have a hard time comprehending how that ancient world functioned. Genesis 1:1 simply tells us that God created the Earth, not how or when or what processes He used to prepare the planet for humans. But because God used a process, we can locate resources far underground. If He had simply “zapped” the planet into existence, we would have no clue about where to look for oil or coal or various minerals.

Proverbs 8 talks about the wisdom that allowed the production of all we see and use today. When we hear about a find like this giant millipede, it underlines how carefully God planned for our existence. Today, our challenge is to take care of the planet by preserving what God has given us rather than wasting it.

Oxygen Generators and More

They are microscopic plants. You may never see them individually, but they exist by the millions on or near the surface of oceans, lakes, and rivers, even in polar regions. Scientists call them phytoplankton which comes from two Greek words that mean “plant drifter.” We call them oxygen generators.

You can see masses of green phytoplankton on the water surface because of the green chlorophyll they contain. Chlorophyll enables them to use sunlight and nutrients from the water to produce the nourishment they need to live. In the process of photosynthesis, they are oxygen generators. Of course, humans and all animals must have the oxygen to breathe, and phytoplankton play an essential role in our climate by controlling the balance between oxygen and carbon dioxide in the atmosphere.

In the ocean, tiny animals called krill eat phytoplankton. In turn, the krill provide the diet for many fish and even for huge baleen whales. Those whales stir up the ocean, bringing to the surface minerals which the phytoplankton need. As whales eat and grow, they take in large amounts of carbon. When they die, their bodies containing the carbon sink to the bottom of the ocean. This well-engineered system helps prevent the build-up of greenhouse gases in the atmosphere.

Phytoplankton are incredibly diverse, with thousands of different species. The microscopic photo shows members of one class of phytoplankton known as diatoms. The carcasses of phytoplankton, algae, and other marine plants deposited on the sea beds long ago became the petroleum we use today.

Diatoms produce silicon shells, and when they die, those shells form deep deposits on the ocean floor. People mine those microscopic shells and use them for what we call diatomite or diatomaceous earth used in industry for fine polishing and for filtering liquids. In addition, gardeners sprinkle diatomaceous earth around their plants to protect them from insect pests. Scientists are also exploring uses for those microscopic shells in nanotechnology.

So, in addition to being oxygen generators, these tiny plants produce energy sources for humans and food for creatures of the ocean and freshwater lakes. Without them, our climate would be much different, and life would be difficult, if not impossible. Chance evolution doesn’t seem to be an adequate explanation for diverse phytoplankton. We see them as another example of design by the Master Designer of life.

The Big Bang and Creation

We receive many interesting questions from our readers, and recently we received this one about the big bang and creation:

“Dr. John Mather, head of the new telescope project, explains that the ‘Big Bang’ is not correctly understood as the universe having one exact beginning point. Rather that its beginning was everywhere at once as evidenced by galaxies all moving away from each other, and residual heat of the “big bang” being somewhat uniform everywhere we look.”

We could blame this misunderstanding on Dr. Fred Hoyle, who coined the term “big bang,” but as teachers of physics and astronomy, we are probably guilty of contributing to it. When we hear the term “big bang,” we think of an explosion. An explosion assumes some material existed, and it blew up like a bomb. That is a mistaken perspective. The big bang didn’t start with a singularity that already existed. The modern understanding of the big bang is that space and time came into existence in a form we call “spacetime.”

We struggle with the concept of the big bang and creation because we cannot envision a condition where neither space nor time existed. We live in a three-dimensional universe and are familiar with X, Y, and Z on a cartesian graph. We know that we can plot any of these dimensions against time. If we move along the ground in direction X at a certain speed, we can plot the distance moved against the elapsed time. When a rocket goes straight up, you can plot Y against time. There is a third direction at right angles to both X and Y that we call Z, and we can plot it against time. But what is time? It’s a fourth-dimensional quantity that you can’t define. You can say it is “what keeps everything from happening at once,” but that is not a definition but a consequence of time.

The big bang concept agrees with Genesis 1:1 that space and time began, but not as an explosion. If space was created, then everything embedded in space was also created. Only action from dimensions beyond our own (X, Y, Z, and time) could do that. So as we consider the big bang and creation, we must ask what could be the source of creation that existed outside of space and time?

You can argue that it wasn’t God, but that doesn’t hold much water. We must account for the design we see in the cosmos, and chance doesn’t even try to do it. The big bang is an excellent proof of creation by God. The Bible describes God as an intelligence outside of space and time who created space and time. We don’t need to understand everything about creation to have faith in God. However, science strongly reinforces the adage that “the more you know of the creation, the closer you get to God.” As science advances in its understanding of the design of the cosmos, the existence of God becomes more and more evident.

Pearl Beauty and Design

We have often reported on how design in nature has helped human “inventors” develop new products or improve old ones. It seems that lowly mollusks can teach humans some lessons from pearl beauty and design.

When a grain of sand or a tiny bit of debris enters the mollusk’s shell, such as an oyster or mussel, the creature goes into a defensive action to protect itself from the irritating particle. The oyster deposits a crystalline form of calcium carbonate known as aragonite. Limestone is primarily calcium carbonate, but it lacks the iridescent appearance of this crystallized form. The smooth layers of mineral and protein which the mollusk deposits on the foreign particle is called nacre (pronounced NAY-ker). The layers of nacre take on a beautiful, iridescent, and shiny appearance that gives pearls their beauty.

The question that has bothered scientists for more than a century is how the oyster can change a jagged or lopsided fragment of grit into a perfectly round and smooth pearl. However, pearl beauty and design remained a mystery until recently when a research team studied pearls from Akoya pearl oysters (Pinctada imbricata fucata) in Australia. First, they used a diamond wire saw to slice pearls in half. Then they polished the cut surfaces and used various electron microscopes to study them more carefully than anyone had done before.

The researchers refer to the layers of nacre as “tablets.” For example, one pearl they studied had 2,615 tablets deposited over 548 days, or 4 to 5 tablets per day. The pearl was only 2.5 mm in diameter, so the tablets were extremely thin. However, the mollusk modulates the thickness of the nacre layers according to “power-law decay across low to mid frequencies, colloquially called 1/f noise.” That means the mollusk uses some math to adjust the thickness of the layers to compensate for irregularities. Where one layer is thin, the next is thicker to self-correct, so irregularities heal themselves in the following few layers.

One of the researchers, Laura Otter, a biogeochemist at the Australian National University, said: “These humble creatures are making a super light and super tough material so much more easily and better than we do with all our technology.” Using calcium carbonate and protein, oysters make nacre 3,000 times tougher than the materials from which they make it. Another research team member, Robert Hovden, a materials scientist and engineer at the University of Michigan, said that understanding how mollusks make pearls could inspire “the next generation of super materials.” That might include materials for better solar panels or for use in spacecraft.

Once again, design in nature gives us some valuable insights. Even lowly mollusks can teach humans some lessons through pearl beauty and design, thanks to the Designer of nature.
