Reducibly Complex

This is Part 10 of the ten part blog debunking the claims made on CreationEvidence.org’s “Evidence for Creation.” This blog examines point #10.

STATEMENT: “The human brain is the most complicated structure in the known universe.”

RESPONSE:  This statement is rather dubious, and there are a number of problems with it:

1. Semantics: What is meant by “complicated”? What is meant by “structure”? This statement assumes we can compare the structural complexities of brains and anything else “in the known universe.” But how are we to compare the structural complexity of the human brain to the structural complexity of the earth, the galaxy, a black hole, dark matter, etc. Wouldn’t it be more prudent to to say it is the most complicated biological organ or even just the most complicated brain in the known universe? But then, that wouldn’t be accurate either, because…
2.  Inaccuracy: …the human brain is NOT the most complicated structure in the known universe. “The dolphin brain is larger than a human brain and more complex in structure.” (see also here).
3. So what?: Even if it were true that the human brain is the most complicated structure in the known universe, so what? Just because the brain is complicated in structure doesn’t make it special. It just makes it complicated. At the very least, this complexity in no way infers that it is “created” by God.

STATEMENT: “It contains over 100 billion cells, each with over 50,000 neuron connections to other brain cells.”

RESPONSE: About half-right. The human brain does contain about 100 billion cells, but the only estimate I could find about neuron connections to other cells estimated the number to be about 7,000, not 50,000. Admittedly, I have not watched the PBS Video (”The Brain, Our Universe Within”) cited as the source for this statement, so it may be that there is conflicting data with regards to neuron connections.

STATEMENT: ”This structure receives over 100 million separate signals from the total human body every second.”

RESPONSE: I have been unable to verify this number in my research, but for the sake of response will assume it is true (as this number is irrelevant).

STATEMENT: ”If we learned something new every second of our lives, it would take three million years to exhaust the capacity of the human brain.”

RESPONSE: How do we know this? What is the math that gives us these numbers? Is the assumption that every new thing learned is stored in one brain cell, and that it would take three million years to store one thing in every one brain cell? (By my calculations, that would take three thousand years, not three million.) What are we defining as exhausting the capacity of the human brain? And why do we have to assume that we learn something new every second? We don’t. I’m certainly not learning anything new when I’m asleep. I know that this statement doesn’t make the claim that we do learn something every second, but why use a number that isn’t accurate to what actually happens?

This statement makes the assumption that the “capacity” of the human brain is entirely for learning. But much of the brain’s 100 billion neurons have nothing to do with learning, but have to do with regulatory functions (i.e. keeping respiratory and heart rates at proper levels), bodily functions (i.e. the manipulation of limbs), or other non-learning based functions. I get the feeling that this statement comes from the idea that we only use 10% of our brains (or some other arbitrarily low number). However, this assumption is highly inaccurate.

The final thing I will say about this statement is that the source cited for this information is a video by Moody Publishers titled “Wonders of God’s Creation”. The front page of Moody Publishers’ website states “Proclaiming the Gospel of Jesus Christ and a Biblical Worldview” and Moody Publishers distributes Christian books and videos, “promoting inexpensive Christian books for Christians to grow and non-Christians to have a quick introduction to the gospel” (Moody Publishers’ “Our History” Page). Using this as a source is hardly the stuff of an unbiased, objective observer, thus making it unscientific and invalidating its use as “evidence.”

STATEMENT: ”In addition to conscious thought, people can actually reason, anticipate consequences, and devise plans - all without knowing they are doing so”

RESPONSE: All true, but how does this serve as “evidence for creation”?

CONCLUSION: “Evidence for Creation” is not making an argument at all in this entire section. It provides nothing to serve as “evidence” for a creation as described in the biblical record. Read the “argument” as a whole and see if you can find what is being argued or what evidence in presented:

“The human brain is the most complicated structure in the known universe. It contains over 100 billion cells, each with over 50,000 neuron connections to other brain cells. This structure receives over 100 million separate signals from the total human body every second. If we learned something new every second of our lives, it would take three million years to exhaust the capacity of the human brain.  In addition to conscious thought, people can actually reason, anticipate consequences, and devise plans - all without knowing they are doing so.”

Even if everything in this argument were true, it makes no point; it would just be a list of facts. So what if the brain were “the most complicated structure in the known universe”? So what that it contains “100 billion cells, each with 50,000 neuron connections”? So what if it “receives over 100 million separate signals from the total human body every second”? So what that humans can “reason, anticipate consequences, and devise plans - all without knowing they are doing so”? What is the argument? How does this prove creation?!

The only thing that I can see as being an argument in here at all is the part about learning something new every second, taking three million years to exhaust the capacity of the human brain. But this is not an argument for creation. If anything, it is an argument that the brain doesn’t exist! I think it would go something like this: “How could we possibly learn something new every second? And how could we possibly live three million years to exhaust the capacity of the brain? Obviously, the brain must not exist.”

“Evidence for Creation” has ten arguments, this being the last; but it really only has nine.

This is Part 9 of the ten part blog debunking the claims made on CreationEvidence.org’s “Evidence for Creation.” This blog examines point #9.

STATEMENT: ”A living cell is so awesomely complex that its interdependent components stagger the imagination and defy evolutionary explanations.”

RESPONSE: The first thing to say about this statement is that it is a great example of the logical fallacy “Argument from Personal Incredulity.” While a living cell is awesomely complex, that complexity does not “stagger” my mind, nor most biologists. If it truly staggered the mind, we would not be able to comprehend its complexity in a meaningful way, or dissect and understand the many parts of its complexity. Just because it staggers your mind doesn’t make its complexity “created” by God.

The second thing is that the interdependent components do not defy evolutionary explanations. In fact, they ARE the evolutionary explanations. The complexity of a living cell developed over billions of years. Let’s not forget that it took approximately 3 billion years of evolution before there were even multi-cellular organisms. What do you think was happening in those 3 billion years? The answer is that what constituted life and eventually evolved into multicellular organisms was developing greater and greater complexity as time passed. If it were not for this complexity, multi-cellular life would never have developed.

This strikes me as being a very similar argument as the intelligent design argument of “Irreducible Complexity,” from which the name of this blog is derived (as an antonym of sorts). I will here only state that irreducible complexity is a very poor argument for intelligent design or creationism (one in the same, in my mind). For more information on irreducible complexity and why it is not a valid scientific theory, I suggest reading the About R.C. page of this blog, the Wikipedia page on irreducible complexity (particularly the Response of the Scientific Community section), or Ken Miller’s “The Flagellum Unspun: The Collapse of ‘Irreducible Complexity’”.

STATEMENT: “A minimal cell contains over 60,000 proteins of 100 different configurations.”

RESPONSE: This appears to be a true statement, though I was unable to conclusively verify it within a few minutes of searching through Google. Nevertheless, 60,000 proteins in 100 different configurations is not staggeringly complex and certainly does not “defy evolutionary explanations,” as noted above.

STATEMENT: “The chance of this assemblage occurring by chance is 1 in 10 4,478,296 .”

RESPONSE: At the time of this writing, that is the exact way it is written in the “Evidence for Creation” article on creationevidence.org. This was a simple copy and paste; the poor grammar and typos are not produced by me.

I will assume that 1 in 10 4,478,296 is actually 1 in 10^4,478,296 (one in ten to the power of four million four hundred and seventy-eight thousand two hundred and ninety-six), a truly impressive number.

I don’t know why I bothered to fix that typo or spell out the number so that people might understand what is actually being argued because the number, while truly impressive, is irrelevant. In fact, the entire statement is irrelevant because evolutionary theory does not state that this assemblage occurs “by chance.” Rather, “Chance certainly plays a large part in evolution, but this argument completely ignores the fundamental role of natural selection, and selection is the very opposite of chance. Chance, in the form of mutations, provides genetic variation, which is the raw material that natural selection has to work with. From there, natural selection sorts out certain variations. Those variations which give greater reproductive success to their possessors (and chance ensures that such beneficial mutations will be inevitable) are retained, and less successful variations are weeded out. When the environment changes, or when organisms move to a different environment, different variations are selected, leading eventually to different species. Harmful mutations usually die out quickly, so they don’t interfere with the process of beneficial mutations accumulating” (Mark Isaak, “Five Major Misconceptions about Evolution”).

CONCLUSION: This entire argument is based on a completely ignorant point of view. If evolutionary theory taught that the evolution of life happens by chance, then the creationists would have a very valid point. But it doesn’t, so they don’t. But the ignorance is spelled out in the first sentence of this argument: “staggers the mind.” It doesn’t stagger the mind. Life’s complexity is impressive, and the complexity is awesome; but we can wrap our heads around it, study it, learn life’s inner workings, and decipher exactly how it is that life, and all the organisms that represent it, exists, lives, survives, dies, genetically mutates, etc. and determine how we got here.
