Why Birds Stand on One Leg

Have you ever asked why birds stand on one leg? We live on a river that has a massive number of ducks in it. When the ducks are resting on the edge of the river, they generally stand on one leg. When guests visit us, they want to know why. Ducks are not the only birds that stand and even sleep on one leg. Geese and Flamingos do the same thing.

The answer to why birds stand on one leg seems to be a simple matter of the application of basic physics. For an object to be stable, its center of gravity has to be directly above the point of support. In my basic physics classes, we have some demonstrations of that principle. A spinning bicycle wheel will do strange things if its pivot point is not under the center of gravity. A top that is not symmetrical will invert when spun with its round side in touch with the table. There are toys that appear to be suspended in space, but in reality, their center of gravity is located at one end which makes it look odd when it is on the edge of a table.

When you stand on two legs, your center of gravity is somewhere between the legs. That may sound stable, but in reality, it isn’t. When you stand, you waver as your body senses that any movement you make throws you off balance. There is a constant muscular effort that counteracts this movement. Just standing for a long time can be fatiguing because a lot of energy is expended to counteract this wavering.

Recent studies with flamingos show that when they stand on one leg, the center of gravity falls directly over the point that touches the ground. Standing on one leg, the bird’s body is quiescent. When the bird is on two legs, there is more muscle movement and the center of pressure on the foot touching the ground changes. If you look carefully at a duck standing on one leg, you will see that it stands a little lopsided, so the mass is completely above the point of support. In addition to energy conservation, standing on one leg allows birds to withstand cold temperatures by keeping one leg close to the body. So thermoregulation is also involved in this odd-looking design.

So if you have ever asked why birds stand on one leg, remember this. Anytime we see something in nature that we don’t understand; it is almost 100% sure that there is a design feature involved. What the animal is doing may look strange, but it has at least one significant function. Truly we can “Know there is a God through the things He has made” (Romans 1:18-20).

Dinosaur Mummy Found

Nodosaurus Dinosaur
Scientists have difficulty finding information about dinosaurs. Much of what we know about them has come from indirect information. I spent a great deal of time studying coprolite, which is petrified dinosaur droppings. By analyzing the solid wastes left by a dinosaur, we can tell what the animal ate. Sometimes we find plant materials–leaves, stems, seeds, etc. Sometimes it’s animal remains–teeth, bone fragments, and complete bones. It is extraordinarily rare to find a complete skeleton of a dinosaur, but now we have something even better.

Until recently we had never found an animal with skin in place and internal organs visible. In 2011 miners working in northern Alberta came across an amazing find that has given scientists their first complete mummy of a dinosaur. This dinosaur was a plant-eating nodosaurus, which means “knobbed lizard.” This animal is complete with its armor, spiky skin, and internal organs. Paleontologists have spent some 7,000 hours carefully extracting the creature. Caleb Brown, who is a researcher on the project, said, “We don’t just have a skeleton, we have a dinosaur as it would have been.”

Dinosaurs were the agents that prepared Earth for humans. Without that preparation, we would not be able to have our crops, our domesticated animals, and our advanced civilization. Dinos were key agents in preparing an ecosystem suitable for us. They lived in an environment very unlike what we have on Earth today. Having a find like this will greatly enhance our understanding of Earth’s history.

It is clear that God used natural processes to prepare the planet for us, and the dinosaurs played an important part in that process. Scientists will continue to study this dinosaur, and in the process, we will learn more about God’s wisdom in design.

Underwater Bees

Those of us who live many miles from the ocean may not think about what goes on under the water. Similar to the land, there is an enormous diversity of plants in the sea. Just like land plants, ocean plants have flowers and pollinate and reproduce. Seagrass grows on the floor of the ocean and provides a habitat for sea turtles, manatees, and many other marine animals. There are some 60 species of seagrass, and those grasses bloom and release pollen. Like land plants, seagrasses need something like the bees that help pollinate land plants. So are there underwater bees?

Researchers at the National Autonomous University of Mexico have reported that hundreds of crustaceans and other small insect-like animals visit plants and bring pollen with them. These invertebrates are the “underwater bees.” They allow ocean vegetation to flourish, along with ocean currents.

As scientists study ways in which carbon can be locked up to avoid high concentrations in our atmosphere, they find that the ocean is a major factor in avoiding the runaway greenhouse heating of the earth. Life in the oceans is essential to life on land.

Here is another design feature of this planet that is critical to the long-term existence of life on Earth. In the 1950s, scientists thought that there were maybe five or six factors that would be critical to the existence of life. The famous Drake Equation of how many planets could have life on them only considered five factors in its original format. Now we know there are a huge number of things that have to be “right” to allow life to exist.

Every time we find a new variable, the odds against life occurring by chance on planet Earth become greater. God’s wisdom and design can be seen everywhere around us. Truly, “the heavens declare the glory of God and the firmament shows His handiwork” (Psalms 19:1).

Watch Out for Zuul!

Has Zuul the monster been discovered? People misinterpret coincidences so quickly that it’s sometimes frightening. Victoria Arbour, who works for the Royal Ontario Museum, published her study of the most complete skeleton of an ankylosaurus dinosaur found in North America in the May 7 issue of the Royal Society Open Science Journal. The dinosaur looks very much like a monster named Zuul portrayed in the 1984 movie Ghostbusters.

The dinosaur had large horns on its head and smaller spikes on its face. It had a long, spiked tail with a massive knob of bone on the end. The full scientific name of Arbour’s find is Zuul crurivastator which means “Zuul, Destroyer of Shins.” Scientists gave it the name Zuul because of the similarities to the Movie monster. The “Destroyer of Shins” is because of its tail.

What is interesting is that we have already received a phone call in which the person calling said that we were in error saying that dinosaurs don’t live today. The reason was that Zuul had just been found in northern Montana and the filmmakers must have seen this animal. (The fact that the fossil was originally discovered in 2014 didn’t seem to make any difference to the caller.)

We would suggest that the similarity is a coincidence. If the people who made the movie Ghostbusters claim they based the creature on something they saw, we would like to ask where they saw it. They haven’t made that claim, and we are pretty sure they won’t. Demand evidence for all claims and make it especially strong when the claim is extraordinary.

Skeptic Challenges Answered

Skeptic Challenges

DOES GOD EXIST? maintains a Facebook page with daily postings. We often get challenges and questions from atheists and skeptics or those who are seeking for answers. We want to share the following conversation from Facebook. The article we posted was about the way the tendons in the legs of various animals and birds are designed in a way that allows them to sleep while standing, hanging upside down, or perched on a branch. The article ended like this:

DGE?-…If a human falls asleep while standing up, it can be dangerous. It’s also very uncomfortable when we have to stand while we are sleepy. For some animals sleeping while standing comes naturally. It’s all a matter of design. Such a simple thing as the position in which we sleep is a reflection of the incredible design that is built into all living creatures.

SKEPTIC- Are you so willfully ignorant that you refuse to do any research?

DGE?- Please explain what you mean.

SKEPTIC- You talk about stuff like this like it’s some kind of universal mystery, but there’s already a scientific explanation

DGE?- If you read this again, you will not find any place where we said it’s a mystery. There are explanations for this and most of the other things that we have presented on this page. The few times when we present things which cannot be explained, it’s usually because science has not yet discovered the answer. What science does is to try to discover how God did it. I think that’s why God gave humans curiosity. Solving the “mysteries” makes life fun and challenging. The point we are making on this page is not that these things are mysterious. The point is that they show design and engineering–not merely random chance.

SKEPTIC- Science is not just a way to discover how your god did it. It’s a way to find out how, if, and why things work. Before you look for how Yahweh did it, the intellectually honest thing to do is to find out IF he did it.

DGE?- That’s a good point. Science does look for how things work–and why. The “why” leads us to the question, “Do the facts of how this works indicate that it could have happened by chance?” That leads to the question of, “Is it rational to think that this could have happened as a result of random accidents without any intelligent design or planning?” The more we see apparent design in the world around us, the more we realize that it takes more faith to believe all those “designs” happened by accident than to believe they had a Designer.

SKEPTIC- Prove it was designed. Provide evidence to back up your assertions

DGE?- You say I should prove my assertions. You might want to look back to see what my “assertion” was. It was that there is apparent design in the world around us. Someone you may have heard of wrote, “Biology is the study of complicated things that have the appearance of having been designed with a purpose.” Even biologist Richard Dawkins sees apparent design in living things. So you can say, like Dawkins, that the apparent design is only in your imagination and is totally the work of natural selection acting on random mutations. Or you can say there really is a Designer. I would suggest that design shows intelligence. I can’t prove that God exists, and you can’t prove that He doesn’t exist. All that we can do is look at the evidence and reach our own conclusions.

SKEPTIC- When someone like Dawkins says there’s a “design” they don’t mean some guy sitting in the clouds with blueprints of every species, they mean that different animals have special means of doing things to survive (stuff like horses having hooves and fish having gills). This is not proof of Yahweh or any deity.

DGE?- If your concept of the God you don’t believe in is “some guy sitting in the clouds”, then you have a very juvenile concept of God. I don’t believe in that kind of god either.

More on “Lucy”

In 1974 paleoanthropologist Donald Johanson introduced the world to a claimed ancestor of humans and called it Lucy. The scientific name was Australopithecus afarensis or the “southern ape from afar.” The story is that because the song “Lucy in the Sky With Diamonds” was playing on the radio at the time of the discovery, they nicknamed the specimen “Lucy.”

Lucy is being displayed in museums throughout the world and has had extensive exposure in the United States. The claim is that she is a link giving proof of the evolution of humans from apes. Johanson has a model of human evolution suggesting that apes became erect first, and then their brains developed to make them human. It appears that Lucy’s sacrum and hip might have been arranged in a somewhat vertical position to facilitate erect walking, and Johanson feels that is support for his theory.

The truth is that most of what we know about Lucy and about characteristics that separate humans from apes strongly supports the idea that Lucy was a monkey. This find does not support the claims of those who promote naturalism as an explanation of human origins. Here are some of the problems:

1-The brain size of Lucy was about 422 cc. A human’ brain is closer to 1470 cc or more. Chimps’ brains are around 520 cc.

2-Lucy’s mandible (lower jaw) is V-shaped like a monkey’s, not C-shaped like a human’s.

3-Lucy has short, curved toe and finger bones like monkeys. Humans’ are generally straight.

4-Lucy’s humerus (upper arm bone) and femur (upper leg bone) are the same size. A human generally has a 2:1 ratio in size with these bones.

5-Recent studies have shown that Lucy had an exceptionally powerful upper body. This is typical of apes that spend long amounts of time climbing in trees.

6-Lucy’s rib cage was conical (like an ape) while human rib cages are barrel-shaped.

7-Lucy may, in fact, have been a male. The pelvis is heart-shaped and ridge-less which is typical of males.

In the world of anthropology, researchers are making new discoveries. The problem comes when atheists and skeptics lift a discovery out of context and try to use it as a club against those who believe humans are a special creation of God. They ignore the facts or slant them to whatever model they are promoting.

Earth Movers

They are designed to move dirt. The echidna is one of only two mammals that lay eggs. (The other is the duckbilled platypus.) Every year the short-beaked echidna (Tachyglossus aculeatus), lays one leathery egg which is about the size of a grape. The egg is put into the mother’s pouch, and it hatches in about ten days. Two patches of pores in the pouch ooze milk and the baby, which is called a puggle, laps the milk from the mother’s skin. The baby hangs on to the mother for weeks as she forages. When it the starts growing spines, the mother will put the puggle into a burrow, and it is on its own.

Echidnas get their food by clawing and poking their snouts into termite hills or ant nests. They flick out their sticky tongues and draw in the insects. The echidnas’ toes point backward on their hind legs and forward on the front. Their short legs slant outward, and they move both left feet at once and then both right feet at once, so they rock as they walk. They may look awkward while walking, but they are well-designed to move dirt. Echidnas spend 12% of their day excavating so that in a single year each echidna will churn up 204 cubic meters of soil. That’s enough to bury 100 full sized refrigerators.

Turning over the soil mixes nutrients and aerates the soil to benefit the Australian ecosystem in which the echidna lives. The echidna improves the soil while removing ants and termites making this animal an important part of God’s design for this planet. Everywhere we look we see testimony to the wisdom of God.

Global Citizens

One of the most interesting examples of design in living things is the ability that various forms of life have to migrate great distances for a wide variety of reasons. Sea turtles have an uncanny ability to return to the same beaches over and over to lay their eggs. Whales can travel long distances when they are ready to calve, giving their offspring a greater chance of survival. Migrations can be critical to animals or plants other than the animal making the migration. Sometimes the migration is critical to an environmental ecosystem. The salmon migration in Alaska, for example, is critical to the entire area sustaining plant life and a wide variety of animal life.

When insect migrations are studied, the question of how they make the migrations and why becomes even more complicated. Monarch butterflies make migrations of great lengths even though their life expectancy is too short for any single butterfly to make the entire migration. The champion of insect migrations is the globe skimmer dragonfly (Pantala flavescens). This insect has wide wings that look very delicate, but those wings can carry it for thousands of miles seeking wet seasons when it can reproduce. Migration has spread this insect’s DNA worldwide to every continent except Antarctica. Globe skimmers can fly for hours without landing and have been seen as high as 20,000 feet (6,200 m) in the Himalayas. They are sometimes called wandering gliders because they can glide on thermals in a way similar to birds. They seem to prefer moist winds, and they don’t stop for bad weather.

Migration is a fascinating part of the life of many creatures from whales to insects. Especially when we think of migrating insects like monarch butterflies and globe skimmers, it seems obvious that the ability and desire to make the migration are programmed into their DNA. We would suggest programming needs a Programmer.

How Many Extinct Species?

Atheists often challenge us with the widely quoted statistic that “95 to 99 percent of all creatures that have ever lived are now extinct.” Their argument is that if there were a wise God who created life, he would have done a better job. The skeptics are assuming that they know the purpose for which a wise God would have created those life-forms. Perhaps the extinct species had a purpose of preparing the Earth for humans, and they went extinct because they had served their purpose. But I am assuming that humans are the pinnacle and ultimate purpose of God’s creation. Atheists reject that idea. One of our skeptical followers recently posted a comment referring to “the virus called man,” as if humans are a blight on an otherwise good world.

Another possibility is that perhaps the statistic of extinct species is highly exaggerated. Since the life-forms that have gone extinct are no longer around, how do scientists determine how many species have gone extinct since life began? The number of fossils of extinct species we have actually found is estimated to be about 250,000. So we have direct evidence of a quarter of a million extinct species. According to National Geographic (May 2014), there are at least 1.9 million animal species today and at least 450,000 plant species. If it’s true that 95 percent of the animal species have gone extinct and there are 1.9 million living today, that means that over 36 million have gone extinct. If we have fossils of only 250,000 extinct species (plants and animals) how do we know that there were 36 million others for which we have no evidence? According to National Geographic (May 2014), Stuart Pimm, a conservation ecologist at Duke University, and his colleagues “reviewed data from fossil records and noted when species disappeared, then used statistical modeling to fill in holes in the record.” In other words, they are filling in the “holes” or “missing links” in the evolutionary record to determine how many other species must have existed that disappeared without a trace.

The questions we might want to ask are, “Why do we have fossils of only 250,000 species out of 36,000,000? Why are we assuming that 36,000,000 species have gone extinct based on the evidence of fossils totaling less than seven-tenths of one percent of that number?” The answer to those questions is apparently the fact that naturalistic evolution from single-celled life to humans requires us to make that assumption. Perhaps this gives us something to ponder.

Design Discovered in Insect Migration

It is easy for humans to minimize the design that is needed for life to exist on Earth. How do you feed massive numbers of birds, especially in the spring when winter has taken away most of their food sources, and their food needs are maximized as they lay eggs and feed baby birds? In the past scientists have shrugged their shoulders and imagined that there are food sources we don’t recognize that fill this gap until the summer season generates sufficient seeds and insects to sustain the growing populations. Similar problems exist for many other animals like bats that depend on insects for their nutritional needs.

In the April 2017 issue of Scientific American (page 84), there is an interesting report about previously unknown migrations of insects. We have known about monarch butterflies for some time, but this study by British researchers shows that migrations of insects are massive. Over southern Britain alone there are 3.3 trillion insects migrating. That is an average of 3200 tons of bugs moving through the skies over Britain every year. The study also reports that similar patterns have been observed in Texas, India, and China.

The complexity of this migration is astounding. Insects don’t live long enough for one bug to complete the migration. Researchers found that in some cases six generations were involved to complete a migration. The insects do not just get randomly blown about. They travel in a well-programmed pattern taking advantage of wind direction and speed. The elevation at which they fly to get the strongest support for their journey is carefully chosen. For a number of reasons, spring migrations are different from fall migrations.

We have much to learn from insects. Solomon made reference to ants as an example for us to learn from in Proverbs 6:6-11 and 30:24, 25. In our modern times, we see an amazing design that allows for the feeding of birds, bats, and other forms of life that need insects to survive. Constructing a chance model for all of this takes a huge amount of imagination. Recognizing God as the intelligence that gave this migration pattern to insects makes what we see just another example of knowing there is a God through the things he has made (Romans 1:20).
