Animals that are not closely related can display very similar characteristics. Evolutionary scientists say that these similar traits demonstrate “convergent evolution.”

According to Darwinian evolution, all life forms can trace their heritage to a common ancestor. From that first life form, branches diverged to form a tree of life. At some point, those branches diverge again. When two life forms develop a similar characteristic that their last common ancestor did not have, that is convergent evolution. There are many examples, such as dolphins and bats. Both use echolocation for navigating or finding food, but they cannot be closely related.

Animals that can fly include insects, birds, and mammals such as bats. Nobody claims that these creatures are closely related. However, they all use aerodynamic principles and wings to defy gravity. We see similar mouthparts in animals that suck blood, such as mosquitos and fleas. Both are insects but not closely related. We can say the same for insects that suck nectar from flowers, such as bees and butterflies.

Many plants produce edible fruits to encourage animals to scatter their seeds. That includes tomatoes, apples, and raspberries – which are not related. We find similar types of eyes in very dissimilar animals. Birds, butterflies, and even some plants use structural coloration, even though they are unrelated and live in very different ecosystems.

According to evolutionary scientists, one of the most dramatic examples of convergent evolution is found in thousands of plants that use ants to disperse their seeds. The plants attach “food bodies” called elaiosomes to their seeds. The elaiosomes are rich in nutrients to attract ants. The ants carry the seeds to their colonies, where they eat the elaiosomes and discard the seeds. How did over 11,000 plant species develop this technique more than 100 times independently? Evolutionists call it convergent evolution. Could it perhaps be evidence for design in plants?

Evolutionary scientists often give pat answers to explain how various species evolved the same traits independently. However, they say that all of these and many more examples of similarities in unrelated animals show convergent evolution. In other words, evolution is intelligent and uses the same ideas in various species. Or we could say that an intelligent Creator has used the same creative ideas in multiple species. Which is the best explanation? Evidence for design in living things calls for a Designer of life.

Does Naturalistic Evolution Explain Life?

Human Cell - Does Naturalistic Evolution Explain Life?

George Gaylord Simpson wrote in his book The Meaning of Evolution (1949), “It is already evident that all the objective phenomena of the history of life can be explained by purely naturalistic…materialistic factors.” In other words, neo-Darwinism explains life. With that in mind, he writes, “Therefore, man is the result of a purposeless and natural process that did not have him in mind.” Despite Simpson’s confidence, does naturalistic evolution explain life?

It is worth noting that Simpson began the paragraph from which I took the above quotes with these words, “Although many details remain to be worked out…” That is an understatement! Those who insist that naturalistic, materialistic evolution explains life completely are purposely overlooking “many details.” Does naturalistic evolution explain life? Here are a few of the problems with that explanation:

The Origin of Life- How did non-living matter become alive?

The Origin of the Genetic Code- DNA contains a massive amount of information, and information originates from intelligent sources.

The Origin of Sexual Reproduction- Most plants and animals reproduce sexually, requiring both male and female gametes. How did this complex process originate and continue?

The Lack of Transitional Fossils– If the evolution of all life has been a gradual process, why don’t we see an abundance of fossils showing transitional stages between life forms? How can you explain the sudden appearance of life forms, such as in the “Cambrian Explosion,” which Darwin admitted was a mystery?

The Development of Complex Organ Systems How could they happen by gradual changes?

The Development of Irreducibly Complex Molecular Machines– They exist within every living cell and require every part to be in place for them to function. Therefore, explaining their origin through a step-by-step process seems impossible.

Mathematical Difficulties- Mathematicians have calculated that the number of gradual changes required to go from unicellular life to all of the diverse life forms, including humans, would be mathematically impossible within the span of Earth’s 4.5 billion years of existence.

Barriers Between the Types of Life Forms- It is possible with intelligent breeding to produce new varieties of dogs, cows, or roses. However, they are still dogs, cows, or roses. The evidence for one type of living creature evolving into another life form is lacking.

Those are just a few of the details that “remain to be worked out.” Darwin recognized some of them, such as the biological big bang of the Cambrian era and the lack of intermediate fossils. He expected those details would be resolved in the future. More than a century and a half later, there is still no resolution to those problems, and many more have been added to the list.

Does naturalistic evolution explain life? Many scientists accept it because the scientific community would shun them if they didn’t. Others accept it not because of its explanatory power but because they see no acceptable alternative. So when someone says that evolution has disproven the need for God, remind them that these are only a few of the reasons why naturalistic evolution falls short of explaining why we are here.

Can Evolution Explain Life?

Can Evolution Explain Life?
In the final days of 2022, we are looking back at some of the major topics we have previously covered.

Over the past two days, we have considered dinosaurs and the age of planet Earth. Some suggest that accepting that Earth is ancient means that evolution explains life. Can evolution explain life? “Evolution” is a very broad term that can mean many different things. However, we have said before that evolution can’t explain everything. Here are some links to examine:

These links are only a sample of the many articles we have published on the topic of evolution. You can go to our DoesGodExist.today website and use the search box to find articles on this or other topics. Can evolution explain life? The short answer is “no.” Naturalistic evolution also cannot explain the apparent design we see in nature, and we will deal with that tomorrow.

Evolution Has Multiple Meanings

Evolution Has Multiple Meanings

Yesterday, I mentioned that I sometimes get people to think by saying that I believe in evolution. For some, the word only brings to mind the concept of “man from monkey.” However, evolution has multiple meanings. We looked at three of them yesterday, and none of the definitions say anything about the existence of God. So here are two more evolution concepts.

#4. MICROEVOLUTIONARY CHANGE. These are changes in a biological population over time, usually in response to environmental factors. We see this in viruses evolving to become resistant to drugs. Humans have created new breeds of dogs and cattle through microevolution. In the Bible, Jacob used microevolution in dealing with Laban’s flocks. (See Genesis 30:31-42.) Microevolution, change within a species, is the basis of modern agriculture.

#5. MACROEVOLUTION. This is a process of change from common descent. The key word is “process” and describes how, over time, it can lead to a new species. In microbiology, a microbe may get its DNA mixed up with the DNA of another microbe and produce a new species. Farmers in California can tell you about insects that evolved with the ability to cause damage to crops. Some plants have changed to the point where they are no longer fertile with the original plant from which they came. Fish have also speciated.

Is macroevolution a tool God uses to produce the massive numbers of new species in the world today? To suggest that macroevolution happens only by chance requires more faith than believing that God built a system allowing new plants and animals to exist on a changing Earth.

So, we see that evolution has multiple meanings. But, no matter what definition we use, it simply describes how God has operated and continues to operate. So, when I say that I believe in evolution, you must know what I mean by that. As we noted yesterday, everyone believes in some form of evolution, but that does not disprove God’s existence.

I Believe in Evolution

I Believe in Evolution

I have, on occasion, made the statement that I believe in evolution. My purpose for saying that is to get people to think. What does “evolution” mean? For many people, the statement means “man from monkey,” and that is as far as they go. There are at least five ways in which people use the word” evolution.” None of them have anything to do with the existence of God. Think about the ways people use the word “evolution.”

#1. ANY CHANGE OVER TIME. We talk about stars evolving from blue hot stars to red dwarfs. We speak about an athletic program evolving. This is simply change over time and has no relevance to our faith.

#2. CULTURAL EVOLUTION. A cultural group may change radically over time due to many things. America has evolved from a country made mostly of immigrants to a country made of people born in this country. Our nation has evolved, and even our vocabulary recognizes this. When I was a kid, America was perceived as a “melting pot” where we could all be one and leave our ethnicity behind. That has evolved into a pluralistic society where people determine their ancestry and try to retain it. That evolution has brought enormous political implications,

#3. PROGRESSIVE EVOLUTIONARY REVELATION. Our understanding of the atom has evolved in my lifetime. My chemistry class in high school and college taught me that the atom had a nucleus with electrons orbiting it in concentric circles around that core. Now, when I teach chemistry, I talk about orbitals and electrons moving in figure eights and cloverleaf patterns in various numbers. Knowledge can change understanding, and that is evolutionary revelation. The Bible uses evolutionary revelation, with the Old Testament introducing the nature and operation of God and progressively revealing the nature of Jesus Christ and the future of believers.

So, when I say that I believe in evolution, you must know what I mean by that. If anyone says they do or don’t believe in evolution, ask them to define what they mean by “evolution.” The truth is that everyone believes in some form of evolution. Tomorrow, we will look at the two remaining primary uses of the word.

The Bible is Too Hard to Understand

The Bible is Too Hard to Understand

What is the number one reason why people have trouble understanding the Bible? It isn’t the language. It isn’t what translation you use. Also, it isn’t because you need a high level of education to make sense of it. Jesus taught things that are easy to understand. On the other hand, Satan leads us to say the Bible is too hard to understand to justify why we are not following what it says. In the Sermon on the Mount (Matthew 5-7), Jesus was talking to common folk like us. The Jewish scholars may have had a hard time understanding His message, but the common folks did not.

Think of what is hard to understand in today’s world. Can anyone make sense of the war in Ukraine and the mindset of the Russian leaders who are bringing such pain and suffering to innocent people? Why do evolution and “survival of the fittest” have such an attraction to people of the world? Why are we obsessed with video games that bring images of fighting, death, and destruction into our homes? Why is sexual misconduct front-page news every day? The physical world doesn’t make a lot of sense.

Until you get your mind around the fact that the Bible and the teachings of Jesus are devoted to the spiritual, you will struggle with it. Jesus said, “my kingdom is not of this world” and “don’t worry about tomorrow.” The idea of agape” love has meaning only if you understand the spiritual and are not hung up on material desires. If you think the Bible is too hard to understand, you are probably thinking only of the material realm.

A classic example of material thinking is confusion about the concept of heaven and hell. In 1 Corinthians 15:42-44, Paul writes about the change that takes place when we die. This passage uses two Greek terms: “psychikon soma” refers to our physical body, and “pneumatikon soma” refers to our spiritual body. If you picture heaven and hell as physical places, you will get confused. This passage makes it clear that it is our spiritual makeup that inherits hell or heaven, depending on the choices we make in life.

We may not be able to imagine the joy of a spiritual existence without time or pain or suffering. However, we can understand that hell is not a place in the center of the Earth with demons with red suits and pitchforks tormenting us.

Jesus offers freedom from all the misery and fears of this physical existence. That is REAL freedom. If you think the Bible is too hard to understand, train yourself to think in spiritual terms. Then the Bible and what it offers will make sense to you.

Vulture Bees and Evolution

Vulture Bees and Evolution - Bee in the Trigona genus
A stingless bee in the Trigona genus

One of the interesting design features that we see in the biological world is how waste material is recycled into the environment. When something dies, all of its body must return to the bio-system. Otherwise, the bodies of dead animals and plants would cover Earth’s surface. Vultures and hyenas play an essential role in recycling dead bodies. In past columns, we have written about birds that eat bones. Vulture bees are another agent that takes a dead carcass and reduces it to the elemental constituents.

We are all familiar with bees that flit from flower to flower, searching for nectar. Vulture or carrion bees are three species of stingless bees in the genus Trigona, living in the jungles of Central and South America. To prevent them from getting sick on rotting meat, they have the same gut bacteria as vultures and hyenas.

The jungle poses a different environment from open terrain. A dead animal carcass can quickly turn slimy and stinky in the warm and humid jungle environment. However, vulture bees have a digestive system that can handle any dead animal, even lizards and snakes.

Studies of the vulture bees show that they have one-third more acid-producing gut bacteria and some microbes not found in other bees. Vulture bees regurgitate some of the meat they eat into their nests, where it serves as food for young bees, and their gut bacteria prevent further decay of the meat to protect the colony.

Researchers trying to give an evolutionary explanation
to the existence of these bees face a problem. According to Science News, entomologist Jessica Maccaro of the University of California expressed it well: “It’s hard to know which evolved first – the gut bacteria or the bees’ ability to eat meat. But bees probably first turned to meat because there was so much competition for nectar for food.”

It is hard to imagine a bee choosing to eat meat to reduce competition for food. It seems more plausible that vulture bees are part of God’s designed system to recycle nutrients from dead material to protect the environment.

Evolution Is Not Creation

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.

Barais 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.

Edward O Wilson Was an Authority on Ants

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.”

The Missing Link in Human Evolution?

The Missing Link in Human Evolution?
Taung child – Facial forensic reconstruction by Arc-Team, Antrocon NPO,
Cicero Moraes, University of Padua – CC-BY-SA 4.0

In his 1871 book The Descent of Man, Charles Darwin hypothesized that the evolutionary ancestors of modern humans originated in Africa. He pointed out that African apes most resemble humans, but he lacked fossil evidence to support his conjecture. The missing link, as it was called, showed up more than 50 years later.

In 1924, some miners working in a limestone quarry in Taung, South Africa, found a fossil of a child. Anatomists determined that this 3-to-4-year-old child had some humanlike and some apelike features. They called this “Taung Child” the missing link between apes and humans. Scientists gave it the name Australopithecus africanus, which means southern African ape.

Critics pointed out that young apes have similarities to young humans, but the resemblance goes away as they mature. However, racist attitudes were strong at the time, and eugenics was accepted as real science. Meanwhile, anthropologists were busy categorizing people into races. Western researchers wanted to justify their claim that Africans were more primitive and less evolved than other people, thus justifying slavery and racism.

One of the challenges to people who believe the Bible is making sense of the fossils and interpretations we read about or see in a museum or video documentary. The basic proposal of the “Does God Exist?” ministry is that science and faith are friends. We are interested in understanding–not conflict or debate. As science makes discoveries in various fields, our understanding may grow. We are seeing more evidence for God’s existence in the design of the universe and life.

The history of paleoanthropology has shown that people have used scientific discoveries in political battles and as justification for slavery, eugenics, and racism. The Bible simply says God created man of the dust of the earth. It does not tell us how long ago or give any other details. The most important thing is that He created humans in His own image (Genesis 1:27). That spiritual creation makes ALL humans equal and of infinite value. Christians recognize that fact (Galatians 3:26-29). Even scientists studying mitochondrial DNA have determined that every human alive today can be traced back to one woman they have called “Mitochondrial Eve.”

As science continues to look for the missing link, paleoanthropologist Bernard Wood said that from a scientific perspective, “Our origin story is a work in progress.” In other words, even scientists have trouble making sense of the fossils. Scientific discoveries in various fields may tell us more about how God did what He did, but science cannot tell us how to live successfully. Only the teachings of Jesus Christ that we find in the Bible can do that.
