Evolution Is Not Science

Last week, as I'm sure you've heard by now, children's TV show host Bill Nye 'The Science Guy' released the following video, entitled "Creationism Is Not Appropriate For Children":



The news media immediately jumped on it, and that's how I heard about it. Frankly, I was shocked at what I heard, not because I believe that God created the cosmos (although I do believe that), but that Bill Nye apparently has a few of his facts confused. He also clearly thinks that anyone who doesn't believe what he believes is an idiot.

Here are a few of the facts that Mr. Nye is getting wrong:
  1. "When you have a portion of the population that doesn't believe in that, it holds everybody back, really." How can he say this immediately after saying "I mean, we're the world's most advanced technological [country]... generally, the United States is where most of the innovation still happens"? Does he think that Americans never believed in creation until recently? Clearly it hasn't held us back yet. It could be argued, based on those two statements alone, that belief in evolution has held everybody else back.
  2. "Evolution is the fundamental idea in all of life science, in all of biology. It's like, it's very much analogous to trying to do geology without believing in tectonic plates." How is evolution fundamental to understanding biology? Is he saying that if someone chooses not to believe that one species can, over time, bring forth a different species, that that person is not able to become a biologist or a physician? He might want to discuss that with the excellent Christian doctor who has kept me healthy for many years now.
  3. "Your world just becomes fantastically complicated when you don't believe in evolution." What's more simple than "I think someone made these complex living things in the world around me"? I suppose "Over the course of millions or billions of years, directed by forces which we cannot observe or repeat, counter to the observable fact that organized things in our world tend to deteriorate instead of becoming more organized, simple creatures suddenly appeared out of nowhere for no reason and then slowly became more complex creatures, guided by no intelligence at all" is much simpler.
  4. "...here are distant stars that are just like our star but they're at a different point in their lifecycle. The idea of deep time, of this billions of years, explains so much of the world around us. If you try to ignore that, your world view just becomes crazy, just untenable, itself inconsistent" Bill here seems to misunderstand something about believers in creation. Not every believer in creation believes in the "young Earth" hypothesis which says that although the universe seems very old, it actually is only something like 6,000 years old (or maybe some other figure, but you get the picture.) In fact, there is no reason that someone who believes that an intelligence created everything can't also believe that that intelligence created it billions of years ago. Young Earth is not the same topic as evolution, although they may often be part of the same arguments.

    This is the first time in the video, by the way, that Mr. Nye implies that people who do not believe in evolution are not very bright. More on that later.
  5. "And I say to the grownups, if you want to deny evolution and live in your world, in your world that's completely inconsistent with everything we observe in the universe, that's fine, but don't make your kids do it because we need them. We need scientifically literate voters and taxpayers for the future. We need people that can—we need engineers that can build stuff, solve problems." Obviously, if you do not believe in evolution, you can not understand science, "build stuff" that requires understanding of engineering, or "solve problems." Hundreds of thousands of scientists, engineers, astronauts, computer programmers, and generally very intelligent people who doubt evolution would beg to disagree.
  6. "You know, in another couple of centuries that world view, I'm sure, will be, it just won't exist. There's no evidence for it." On the contrary, in recent years the evidence against evolution has been mounting... in fact, if there is anything that lacks evidence, it is the argument that simpler creatures can and have managed to change themselves into more complicated creatures. Human beings cannot even force evolution to happen, and to our knowledge, we are the more complex and intellectual creatures on Earth. The best we can do is make creatures mutate, but we can't make a Spider Man or a Wolverine... usually the mutations we create result in the death of the mutant. Mutation does not make creatures better. It usually kills them. It certainly doesn't turn one species of animal into a different species. And if even the most complex species on the planet can't make it happen, how can a one-celled microbe make it happen?
The thing I find offensive about Bill Nye's video, though, is not his inaccuracies, but his arrogance. He leaves no room between "smart like me" and "crazy people who can't understand the world around them." He implies that science and evolution are one and the same, but that's just not the case. Evolution is not science. The Merriam-Webster online dictionary defines the Scientific method this way: "principles and procedures for the systematic pursuit of knowledge involving the recognition and formulation of a problem, the collection of data through observation and experiment, and the formulation and testing of hypotheses." Did you notice how the scientific method involves observation and experiment? So far there has never been a bona-fide observed case of evolution. We haven't been able to turn cats into anything but cats, cows into anything but cows, daisies into anything but daisies, humans into anything but humans. Squirrels give birth to baby squirrels. Chicken eggs hatch and chickens come out. Evolution has as much scientific validity as Mary Shelley's story of Dr. Frankenstein giving life to an assembly of body parts by shooting them with lightning. Neither experiment, Frankenstein's Monster or Darwin's Evolution, has ever been repeated. Experimental results that are not independently repeatable are scientifically suspect.

And yet Bill Nye and others like him do exactly what they accuse creationists of doing: they shove their dogma down the throats of others. They pretend that something they cannot observe or make happen is a scientifically proven fact, and they call people names if they are disagreed with. I've even heard accounts of very qualified scientists suffering bullying within their professional circles for advancing ideas that exclude evolution. Some scientists who believe in creation actually remain "in the closet" because they fear that their career will suffer if they buck the party line on evolution. By using the word "crazy" to describe the views of creationists and by implying that they live in a dream world, Mr. Nye has shown that he has no respect for those who have views counter to his own. It's shocking that someone who aligns himself with the scientific establishment would show such disdain for the views of others.

Even if I believed in evolution, that's not the kind of attitude I want to teach to my children. Hopefully, the children of tomorrow will respect others' viewpoints, even if they disagree with them. Evolution or not, intellectual arrogance is definitely not appropriate for children.

Shallow Waters

I'm reading a book called The Shallows: What the Internet Is Doing to Our Brains by Nicholas Carr. The book sprang from an article in The Atlantic Magazine entitled Is Google Making Us Stupid? The basic premise of the article, and of the book so far (although I've got some distance to go before I'm finished) is that our fast-paced, plugged-in, sound-bytes-on-YouTube and 140-characters-or-less-on-Twitter straight-to-your-cell-phone-or-iPad-whichever-is-faster world, people are actually losing their ability to concentrate on one thing for an extended period of time. It's been very interesting reading; maybe I'll share my take on the entire thing here once I'm done with the book. But one part I read this morning rang a bell for me, and I thought you might find it interesting.

The second chapter discusses the "plasticity" of the human brain, meaning whether or not the adult brain can "change" itself, or whether the brain is "wired up" in childhood in such a way that it is unable to physically modify its neural passageways later on. Apparently, for most of history, the brain was thought to be unchangeable after childhood, but in the second half of the 20th century, researchers began to discover that the brain does indeed "rewire" itself, even in adults. For example, if a person loses a limb, the part of the brain that previously was used to control that limb, accept sensory input from that limb, etc. is soon re-purposed for other tasks. That's most likely the reason that blind people often develop sharper sense of hearing, smell, etc. than sighted people; their brains have reused the visual cortex for something else. In fact, there have been experimental therapies used on people who have lost the use of some part of their bodies due to strokes or other head injuries that indicate that if you perform repetitive tasks with that part of the body often enough, you can begin to regain your use of it. Your brain is sensing that you need some power for that body part, and it's sending reinforcements out to work on it. A part of your brain that you are not using for something else is being given the chance to come into use.

What really stuck with me, though, was a section that started with "It's not just repeated physical actions that can rewire our brains. Purely mental activity can also alter our neural circuitry, sometimes in far-reaching ways." It goes on to tell about a study of London cab drivers that showed that people who spend their days performing the spatially-intense task of driving have larger posterior hippocampuses (the part of the brain that handles spatial representations of the person's surroundings). The part of their brains that they constantly stimulate begins to develop. Then it talks about another study in which people with no experience playing piano were taught to play a simple melody, and then one group was told to practice the melody on a piano for a certain amount of time per day, and another group was told to think about playing the song, sitting at a piano, for the same amount of time. Both groups experienced the same kinds of changes in their brains. "Their brains had changed in response to actions that took place purely in their imagination—in response, that is, to their thoughts," Carr reports. "We become, neurologically, what we think."

That the human brain can be physically changed should not be too much of a surprise to any Christian. Romans 12:2 says "Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect." Obviously, the way to find out the will of God is to spend time in the Word of God and in prayer, so that verse tells us that our mind can be "transformed" and "renewed" if we do so. By the repetitive action of reading God's Word, studying it, thinking about it, going over and over its basic teachings, submitting our lives to God in prayer and worship, even science tells us that we can "change our minds" and make them work in a certain way. Wouldn't it be great if your mind could operate in such a way that God's thoughts became your thoughts? That's not the way it is naturally, you know. But by spending time with God, using our brains to think about His ways, we can "become what we think." If you approach God with an open heart, He will pour His life into you, and you will be transformed. Your mind will begin to think in terms of God's ways. You might even find things that are not of God less desirable, as His desires become yours. Get into the habit! You'll be glad you did!
I have stored up your word in my heart,
       that I might not sin against you. (Psalm 119:11 ESV)
