Majesty in Miniature

Majesty In Miniature

“Majesty in Miniature” is the title of an interesting article in the July 2017 issue of National Geographic (pages 99-118). The article is about the amazing hummingbirds.

Scientists have had a hard time getting data as they try to understand how hummingbirds do what they do. The birds fly at speeds up to 35 mph (56 kph) and they have a “reverse gear.” Their metabolic rate is the highest of any vertebrate on the planet. For every minute they are in flight, they drink more than 12 ounces (355 ml) of water. They consume more than their body weight of nectar every day. Their tongues lap up to 15 times a second. Proportionally their brain is one of the largest in the animal kingdom making up 4.2% of their body weight. It is only with the advent of high-speed cameras and advanced wind tunnels that some of the mysteries of the majesty in miniature have been answered.

Hummingbird brains have a large hippocampus which allows them to remember locations. Their brain has a large lentiformis mesencephali motion sensor which gives the bird stabilization when flying. It has a small arm wing which allows wrist motion to control a larger area of the wing leading to a more powerful upstroke. When a hummingbird hovers, it rotates its wings between the upstrokes and the downstrokes making a figure eight motion. This motion creates vortexes that allow both the downstroke and the upstroke to provide lift. Birds such as pigeons push down to propel forward, but there is no lift in the upstroke. The design of the hummingbird wing gives it the unique ability to get lift out of both strokes.

The design of all of these features defies any chance explanation. Nearly everything the hummingbird does is unique to that species. We don’t see birds with some of these characteristics, and yet all of them are essential to the hummingbird’s survival. Indeed this bird is majesty in miniature, and a testimony to God’s wisdom and design. He has equipped all creatures to live in their particular, unique environment.

Human Evolution Theories More Confounded

Human Evolution Theories More Confounded
For many years the papers have reported on anthropologists finding the remains of human ancestors in Ethiopia, eastern Africa. In the past several weeks there have been headlines saying that “the oldest fossil of Homo sapiens” has been found in Morocco which is in northeast Africa. It seems that each new find makes human evolution theories more confounded.

Anthropologists working in Jebel Irhoud, Morocco, found fossils they claim are much older than those found in east Africa. The specimens have a lower jaw which matches Homo sapiens but the brain cases are long and low which is more indicative of apes or monkeys. They also found 14 stone artifacts which they associated with those fossils. The original report said that the tools were found with the fossils. Later reports indicate the tools were found in the strata above the fossils indicating they might not have been produced by those individuals.

Scientific theories about how humans came into existence are always changing as new data becomes available. The classic theoretical model of human evolution in recent years has maintained that humans arose in east Africa and migrated elsewhere. That is apparently not the case, but this new find will be debated and discussed by the experts for many years.

The Bible does not address the evolution of apes or monkeys. We are simply told that animals reproduced after their kind. There is no indication of how many kinds there were, or how much their genetic makeup varied as the years went by. The Bible says that God created man and woman in His own image. That spiritual quality of humans is the thrust of the biblical account. Modern human’s origin in the Fertile Crescent area of what is now Iraq is not questioned by very many people. That is also what the Bible tells us. Human migration throughout the world and the racial variations that developed to help people adapt to different climates is without a doubt.

The fact that apes and monkeys evolved and adapted to the varied climate of Africa is interesting and not surprising. The assumption that their evolution jumped to produce modern humans with all of all of the human characteristics and spiritual capabilities is a leap of faith. New data will keep developing new ideas and theories, but humans as a special creation of God will not be changed. The discovery of the changes in creatures that in some cases looked physically like us makes human evolution theories more confounded.

Moderate Drinking and the Brain

Moderate Drinking
Does moderate drinking cause physiological problems? We see a lot of misleading information in the media about the effects of alcohol. There have been studies linking consumption of alcohol to longer life expectancy. We have pointed out that the agents causing health benefits from drinking wine are the flavonoids in grapes. Alcohol is not the agent of health benefits.

A recent study published in the British Medical Journal reports that long-term studies show a negative effect in the brain of moderate drinkers. The study defined moderate drinking as weekly doses of 8 to 12 small glasses of wine, bottles of beer, or shots of liquor. It followed 527 British citizens for 30 years, and the subjects were “predominantly white middle-class men.”

The study showed that moderate drinkers were more likely than nondrinkers to develop brain changes that might precede or accompany memory loss. They also were more likely to show a more rapid decline in a language fluency test. Moderate drinkers were three times more likely than nondrinkers to show shrinkage of the hippocampus area of the brain–a change that accompanies dementia. Heavy drinkers showed the most shrinkage.

Claims that moderate drinking is healthy and improves the quality of life are simply not true. Alcohol continues to be the most destructive recreational drug.

We Need Lightning to Survive on Earth

We Need Lightning
Most of us have had some experience with lightning. The chances are that our experiences have been terrifying and destructive, and we may view lightning as a bad thing. You may wonder if we need lightning. The short answer is, “Yes.” Lightning is a good thing, and there are many things we are still learning about it.

Lightning helps produce the nitrates and other nitrogen compounds that are needed by all living things on Earth. The process is called “nitrogen fixation, ” and it is vital to our very existence. Water droplets in the air carry an electric charge. That charge can accumulate to dangerous levels unless there is a way to neutralize it. That’s where lightning comes in.

One of my favorite demonstrations as a physics teacher was to get a very small flow of water going from a faucet and then bring a charged rod up to the column of water. The stream of water will bend in response to the charge. That is because the polar nature of the water molecule allows it to have electrical properties. Because of water’s electrical property, lightning is generated to release nitrogen from the air and deposit it in the crust of the Earth as nitrates and other nitrogen compounds that plants need to grow. The plants then feed and protect the animals and us.

Low Earth orbit satellites and high flying airplanes have recently made us aware of other properties of lightning. We have learned that red sprites occur and they have been photographed above large thunderstorms. Other upper atmosphere lightning phenomena include blue jets and terrestrial gamma flashes. Scientists are studying the highly complex nature of lightning to understand how the system works.

The Bible makes many comments about lightning. It tells us that lightning is made with water (rain) even though people at that time totally ascribed lightning to supernatural causes. (See Jeremiah 10:13 and 51:16). Lightning is referred to as a tool of God. (See Job 28:26; 36:30; 37:3, 11, 15; 38:24, 25, 35.)

We are just beginning to understand the design of Earth’s atmosphere and why we need lightning. It continues to be obvious that the more we know of the creation, the closer we get to understanding the power and wisdom of the Creator.

World’s Largest Snake- TITANOBOA

World's Largest Snake
It was the world’s largest snake. Fortunately, it is extinct. The computer-generated picture shows what it might have been like if a human had ever confronted a Titanoboa (Titanoboa cerrejonensis).

One thing that many creationists and evolutionists forget is the fact that Earth’s climate in the past was much different from what it is today. To produce animals of massive size, Earth’s climate would have to be much warmer. The temperatures would have been so high that mammals could hardly survive. Cold-blooded (ectothermic) animals in tropical areas today tend to be larger than ectothermic animals found farther from the equator.

While giving lectures in Colombia, South America, we learned about the snake named Titanoboa. Fossils of more than two-dozen of these snakes were discovered in coal mines in northern Colombia. The name means “titanic boa,” and that seems fitting because it measured 48 feet (14.6 m) long and would have weighed 2500 pounds (1,135 kg). For a snake of that size to live, the climate must have averaged 90 degrees F (32 degrees C). It is difficult to comprehend how any mammal, especially humans, could survive in such temperatures.

Why would God have given this planet such an extreme climate? It was needed to support the world’s largest snake, other huge animals, and the massive vegetation they required. What was the purpose of those animals and plants? That environment made possible the coal, petroleum, and other resources that would later be needed by humans to support an advanced civilization. This is one more indication that the prehistory of the Earth had conditions uniquely designed by God to prepare the planet for human habitation.

Human Evolution “The Road to Homo Sapiens”

Human Evolution “The Road to Homo Sapiens”

Around 1970, Time-Life Books published a mural of human evolution, “The Road to Homo Sapiens.” It became a monstrous success. It was a foldout in a book titled Early Man. It was also laminated and sent to teachers in public schools. This mural became the basis of several movies and even cartoons. What most people don’t realize is that it was quite inaccurate. The artists who made the drawing created the impression that it was a chronological sequence of human history. Actually, the dates were misrepresented, and the illustrations were pretty much fictional. In spite of that fact, much of the American public accepted “pliopithecus-to-modern-man” as a proven fact.

Half-a-century later, the picture is much more complicated and highly contested. Recently in Europe, scientists found older fossils of what were considered to be the earliest ancestors of modern humans. Others found fossils of a group of small-brained individuals apparently ritualistically buried in a cave complex in southern Africa. This find violated the theory that there is a relationship between brain size and human-like activities. Discovered in Indonesia is a very small hominid that supports the view that there is no relationship between brain size and humanism. Names like Homo floresiensis or Hobbits, and Homo naledi or Naledi, and Graecopithecus fill the literature today.

Debates rage among the leading anthropologists about whether brains became larger as Homo species evolved, or whether brain size came first and increased physical size came later, or whether brain size has nothing to do with evolution at all. Interestingly, some of the great geniuses of the past 100 years had very small brains.

The primary source of problems here is the failure to have a good definition of, “What is a human?” The biblical account defines humans as those beings created in the image of God. That does not refer to brain size or any physical characteristic. In reality, we have no idea what Adam looked like, how big his brain was, or any other physical characteristic.

The Bible tells us that “God formed the man of the dust of the ground, and breathed into his nostrils the breath of life; and the man became a living being” (Genesis 2:7). The Hebrew word yatsar is translated “formed.” It is a term used to refer to someone shaping pottery from clay. It’s different from the Hebrew word bara, which is used in Genesis 1:27 to indicate how humans were created in God’s image. Bara is a word used only in reference to what God can do, and that is what makes us unique. You can form a man out of plastic and put clothes on him and put him in a department store window. The body may resemble a man, but it does not have the breath of life, and it does not have a soul.

The fossil record shows us that many creatures in the past may have had some resemblance to humans. The same could be said today. You can visit a zoo and see gorillas, chimpanzees, orangutans, baboons, spider monkeys, Japanese snow monkeys, and others. The fact that there are some common features does not mean we are related.

The anthropological definition of humans deals only with physical characteristics. From the standpoint of human evolution, the road to homo sapiens is very bumpy indeed. The biblical definition of beings created in the image of God gives humans a special identification and a unique role in the world. It’s a role that has eternal significance and should also help us function in a constructive way in the affairs of this life. Humans can act like animals, but no animal can be human. Only humans are uniquely created in God’s image, now and for eternity.

Dark Matter and Black Holes

Dark Matter and Black Holes
Dark matter is the glue that holds our universe together. We have discussed a variety of ways that dark matter is critical to the existence of our solar system and of galaxies in general. We have also reported on unsuccessful experiments to try to find that mysterious dark matter. We have discussed the concept of WIMPS (Weakly Interacting Massive Particles) and the idea of attempting to see dark matter by smashing protons together. Now scientists think there may be a connection between dark matter and black holes.

A new study reported in Scientific American (July 2017, page 39-) reports that primordial black holes are now appearing to be the cause of dark matter. The computer model shows that when the creation process usually called “the big bang” took place, seeds of primordial black holes were produced. Those black holes could cause all of the phenomena that we observe and attribute to dark matter. This would be a much simpler cause of the dark matter than previous models would indicate. Dark matter would be a bi-product of the creation process.

From an apologetic standpoint, this is very interesting. God’s power is so great that when He applied that power in the creation process, massive numbers of primordial black holes were produced. If this hypothesis is correct, it tells us something of the power of God and explains the structure we see in the cosmos. It will be interesting to see if future research will confirm or deny this new observation.

The authors of the research document into dark matter and black holes are Juan Garcia-Bellido and Sebastien Clesse.

Cobra Plant Insect Trap

Cobra Plant
One of the most interesting areas of botany is the functioning of plants that don’t rely on photosynthesis to survive. Recent studies of the California pitcher plant (Darlingtonia californica), also known as the cobra plant because of its shape, have shown that its design is incredibly complex.

David Armitage at the University of Notre Dame has been studying this plant, and in a recent article in Science News (January 21, 2017, page 4) he reported on what is known about this strange plant. It grows in soil rich in serpentine which would kill most photosynthetic plants. The cobra plant survives by being “meat dependent.” Up to 95% of the nitrogen the plant uses comes from insects trapped inside the leaves of the plant.

The curled leaves of the California pitcher plant serve as an insect trap. It draws insects into the leafy trap by secreting a sweet substance. This secretion is not through its blossoms but from a special roll of tissue near the mouth of the insect trap. When an insect enters the small opening under the cobra-like head of the pitcher, something interesting happens. By a method still not understood, the cobra plant draws water up from the soil and creates a pool in the bottom of the “pitcher.” Putting other substances into the trap doesn’t trigger the water. The plant will only respond to an insect. How the plant knows what is a bug and what isn’t a bug is still not understood. The water contains bacteria which lower the surface tension, so when a bug falls in, it quickly sinks to the bottom and drowns.

Another unsolved mystery of this plant is that it has a forked tissue at the top of the trap called a “fishtail” which resembles a mustache with red veins. It does not lure insects into the plant, but its function is still not understood. Armitage says “The only thing fishtails lure, for the time being at least, are puzzled botanists.”

Those of us who see God’s designing hand in the natural world would see the cobra plant as a special design to meet a particular environment. We would point to the Bible in Romans 1:20 where it says, “We can know there is a God through the things he has made.” The complexity of the California pitcher plant supports such a viewpoint in a special way.

Jupiter Comet Shield

Jupiter Comet Shield
Jupiter Struck by Shoemaker-Levy 9

There is a significant amount of debris left over from the formation of the solar system existing in clouds outside the solar system. That debris eventually gets attracted toward the Sun. In 1992 scientists observed Jupiter pulling the comet Shoemaker-Levy 9 apart and breaking it into more than 20 pieces which eventually slammed into Jupiter’ surface in 1994. We learned that we have a Jupiter comet shield to protect our planet.

It is obvious that Jupiter is essential to the survival of life on Earth if for no other reason than the shield it gives us. Right now a spacecraft named Juno is orbiting Jupiter and sending back data and pictures that are amazing. The spacecraft has made five elliptical orbits since last July dipping to within 2100 miles of Jupiter’s atmosphere, collecting data, and taking photographs. ScienceNews.org has some of the amazing pictures.

Here are some things we have learned about Jupiter:

*Polar cyclones 900 miles wide circle the planet.

*Jupiter has a powerful magnetic field about ten times stronger than Earth’s.

*Powerful auroras work in the polar areas of the planet but are different from what we observe on Earth in both structure and function.

*There is a concentrated band of ammonia near the planet’s equator.

There is still much to learn about this giant planet. The observations we are making assist us in understanding how the solar system was formed. They also show us what affect Jupiter has on us today as well as in the future. Psalms 19:1 tells us that “The Heavens declare the Glory of God and the firmament shows his handiwork.” It is an exciting time to be alive and to watch as we use new tools to understand the creation and how God has given us a Jupiter comet shield.

Dinosaur Pseudoscience Part 2

Dinosaur Pseudoscience Fire-breathing
Yesterday we stated that one of the greatest challenges that this ministry faces is the bad science and false claims by creationists, including dinosaur pseudoscience. In addition to the ones we mentioned yesterday, another example is the claim of many creationists that dinosaurs were fire-breathing dragons.

In the Middle Ages, there were numerous stories about flying dragons who breathed fire. In recent years we have seen movies showing everything from Puff the Magic Dragon to How to Train Your Dragon as well as video games showing dragons that look like dinosaurs. Creationists have proposed that dinosaurs had hypergolic chemicals (chemicals that ignite when combined) that they used to produce literal fire. The scientific problems with such proposals are huge. Hypergolic chemicals are highly toxic to biological organisms. Fire going out of an animal’s mouth or nose would cause damage to the tissue. Atheists and biblical skeptics have written numerous articles showing the impossibility of these proposals on a scientific basis.

What is the biblical passage that creationists use to suggest that dinosaurs were fire-breathing dragons? The answer to that question is Job 41. The key word in this chapter is “leviathan.” The word is used three other times in the Bible–Psalms 74:14, Psalms 104:26, and Isaiah 27:1 In all of these references the leviathan is a sea creature. In other non-biblical Hebrew writings the word is used to describe a sea creature, and in a few cases, a sea crocodile is the translation. Job 41:18 says that when leviathan sneezes a light shines and his eyes look like the dawn. Verse 19 says that fire comes from his mouth and verse 20 says that smoke comes from his nostrils. This is poetic language and obviously doesn’t describe the animal anatomically. Verse 29 says that the leviathan laughs and verse 31 says that he makes the sea boil like a pot of ointment. These are obviously poetic descriptions of a very fierce sea creature. It is not a dinosaur living on the land, flying, and belching fire.

There is no valid fossil support for humans and dinosaurs living at the same time, and there is no biblical passage that states it. Cherry-picking a poetic description in Job to back up a denominational belief system is not taking the Bible literally.

Those of us who believe in God are in a war with forces who wish to destroy Christianity and the Bible. Pseudoscience used to defend a denominational understanding of a biblical passage just becomes a tool of those who despise Jesus Christ. It is a tool they use to destroy the faith of bright and well-educated young adults. We must not give them that tool.
