Molecular biologist Douglas Axe calculated that the odds of randomly getting a protein with a particular function was 1 in 10 to the power of 77. To get an idea of how unlikely this is, the number of atoms in all planet Earth is estimated to be 10 to the power of 50. Life forms require many functional proteins, not just one. But there simply hasn't been enough time since the beginning of Earth for it to randomly produce a single one of those functional protein. (see page 40)
I finished reading DBB and quite enjoyed it. I like the way Behe was able to take a difficult subject and make it comprehensible for the layman by using clear and simple language. I especially appreciate the way he uses real life metaphors to explain complex systems, like the thousand lane highway, and the parking garage with sensors. I recognized a few of the pathways and metabolic processes he describes from the biochemistry course I took in Pharmacy school. It would have been cool to have him as a teacher!
Many years ago, I think it was early to mid-nineties, I remember reading a book that talked about evolution. The author made the case, quite convincingly, that natural selection by random mutation was statistically and mathematically impossible (similar to what Windmill Knight posted above). There was simply not enough ‘time' in the universe for the number of random mutations it would take to account for life as we know it to occur. It’s like a million monkeys, hammering away on a million typewriters for a million years, would still never be able to produce Shakespeare. Change “million” into “infinite” and the results are likely to be the same.
Ever since then, I haven't put much stock into Darwin's theory of evolution as a reasonable explanation for the incredible diversity of life on earth. In that sense, DBB was not such a huge revelation for me, but more of a confirmation of something I had already long suspected. It was good to read his explanations though, particularly the problem of irreducible complexity. And his book certainly provides the tools to help bolster one’s argument when talking about evolution with everyday people.
Anyway, as I was reading the book and thinking about all these tiny, incredibly intricate, bio-molecular machines operating inside my body and all other living systems all the time, I kept coming back to the question - what is the force or process driving these perfect little machines? What powers them and makes them go? What is the animating principle behind life itself? On the forum we would probably call it ‘consciousness’ or 'soul' in regards to humans and higher animals. But for now I’ll just call it the ‘life force’.
In relation to this, there was one small part in Behe's book that kind of stood out for me, and when I read read it, I immediately shook my head and thought - “No, that can’t be right”. I’ll reproduce the passage here from chapter 9…
It wasn’t too long ago that life was thought to be made of a special substance, different from the stuff that comprised nonliving objects. Friedrich Wohler debunked that idea.
Of course this 'life force' that we see expressed everywhere in nature is probably not a “substance” as defined above, but there definitely seems to be something, some kind of energy or animating principle that differentiates a living from a non-living organism.
Imagine two goldfish in a bowl, one of them swimming around, the other floating belly-up. Let’s say that the dead fish just passed away a few minutes ago. From a bio-molecular perspective, both fishes contain virtually the same enzymes, receptors and complex proteins as the other, yet in one fish they are working and in the other they are not. There is an obvious observable difference between the two, and though it may not be a physical “substance” per se, to deny some kind of animating life force seems illogical.
So, I went and looked up this Friedrich Wohler person to see exactly what he’s debunking.
Friedrich Wöhler - Wikipedia
en.wikipedia.org
Friedrich Wohler was a 19th century German chemist who is best known for synthesizing urea (an organic molecule) in a laboratory setting. But how did this discovery debunk the idea of a 'life force' that animates all of organic life? Well, apparently it was seen as a direct counter argument to the concept of “vitalism”…
Vitalism - Wikipedia
en.wikipedia.org
A philosophy or belief that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things”.
So, according to mainstream evolutionary science, Wohler's scientific breakthrough debunked this idea of vitalism because one of the tenets of the vitalist philosophy promoted by Jons Jakob Berelius stipulated that "organic" compounds could only be synthesized living organisms.
Wöhler is regarded as a pioneer in organic chemistry as a result of his (accidentally) synthesizing urea from ammonium cyanate in the Wöhler synthesis in 1828.[2] In a letter to Swedish chemist Jöns Jacob Berzelius the same year, he wrote, 'In a manner of speaking, I can no longer hold my chemical water. I must tell you that I can make urea without the use of kidneys of any animal, be it man or dog.'[3]
This discovery has become celebrated as a refutation of vitalism, the hypothesis that living things are alive because of some special "vital force". However, contemporary accounts do not support that notion. This Wöhler Myth, as historian of science Peter J. Ramberg called it, originated from a popular history of chemistry published in 1931, which, "ignoring all pretense of historical accuracy, turned Wöhler into a crusader who made attempt after attempt to synthesize a natural product that would refute vitalism and lift the veil of ignorance, until 'one afternoon the miracle happened'".[4] Nevertheless, it was the beginning of the end of one popular vitalist hypothesis, that of Jöns Jakob Berzelius, that "organic" compounds could be made only by living things.
After reading the passage above, I don’t agree that the discovery of inorganic urea synthesis acts as a plausible refutation to the vitalism hypothesis. It seems possible to me that with the right technology, simple organic compounds could be produced in a lab, and yet there still could be a 'life force' that animates organic systems. I think that this one aspect of Berzelius’s original premise is faulty, but the concept of “vitalism” itself could still be considered a valuable idea to explore.

Jöns Jakob Berzelius, one of the early 19th century fathers of modern chemistry, argued that a regulative force must exist within living matter to maintain its functions.[6] Vitalist chemists predicted that organic materials could not be synthesized from inorganic components, but Friedrich Wöhler synthesised urea from inorganic components in 1828.[7] However, contemporary accounts do not support the common belief that vitalism died when Wöhler made urea. This Wöhler Myth, as historian Peter Ramberg called it, originated from a popular history of chemistry published in 1931, which, "ignoring all pretense of historical accuracy, turned Wöhler into a crusader who made attempt after attempt to synthesize a natural product that would refute vitalism and lift the veil of ignorance, until 'one afternoon the miracle happened'".[8][9][10]
Between 1833 and 1844, Johannes Peter Müller wrote a book on physiology called Handbuch der Physiologie, which became the leading textbook in the field for much of the nineteenth century. The book showed Müller's commitments to vitalism; he questioned why organic matter differs from inorganic, then proceeded to chemical analyses of the blood and lymph. He describes in detail the circulatory, lymphatic, respiratory, digestive, endocrine, nervous, and sensory systems in a wide variety of animals but explains that the presence of a soul makes each organism an indivisible whole. He also claimed the behavior of light and sound waves showed that living organisms possessed a life-energy for which physical laws could never fully account.[11]
There is a pretty strong modern philosophical argument against vitalism that I can understand where it’s coming from. By advocating for an undefinable “force” that animates a living organism, just because this force can’t be isolated, measured, or separated from the organism itself, is akin to saying that the actions of a locomotive is a result of “locomotive power”. It’s a self-referencing, meaningless and unfalsifiable doctrine.
For me, this still doesn’t debunk the idea of vitalism, because this clearly observable 'life force’, like gravity or fire, even though we can perceive it and act upon it, belongs to one of those mysteries of the world that science hasn’t yet adequately explained and still doesn’t fully understand.
I’m going to quote a little bit more from the wikipedia page on vitalism, and do recommend reading the article in its entirety, as it’s all quite fascinating.
Vitalism has a long history in medical philosophies: many traditional healing practices posited that disease results from some imbalance in vital forces. In the Western tradition founded by Hippocrates, these vital forces were associated with the four temperaments and humours; Eastern traditions posited an imbalance or blocking of qi or prana. One example of a similar notion in Africa is the Yoruba concept of ase. Today forms of vitalism continue to exist as philosophical positions or as tenets in some religious traditions.[citation needed]
Complementary and alternative medicine therapies include energy therapies,[26] associated with vitalism, especially biofield therapies such as therapeutic touch, Reiki, external qi, chakra healing and SHEN therapy.[27] In these therapies, the "subtle energy" field of a patient is manipulated by a practitioner. The subtle energy is held to exist beyond the electromagnetic energy produced by the heart and brain. Beverly Rubik describes the biofield as a "complex, dynamic, extremely weak EM field within and around the human body...."[27]
The founder of homeopathy, Samuel Hahnemann, promoted an immaterial, vitalistic view of disease: "...they are solely spirit-like (dynamic) derangements of the spirit-like power (the vital principle) that animates the human body." The view of disease as a dynamic disturbance of the immaterial and dynamic vital force is taught in many homeopathic colleges and constitutes a fundamental principle for many contemporary practising homeopaths.[citation needed]
Perhaps it’s time to consider revitalizing the “vitalism” hypothesis and make it a viable philosophy once more (puns intended).
These are just a few of the thoughts I had while reading Darwin's Black Box. In the meantime, I’m halfway through Stove’s book and will begin reading Darwin Devolves after that.
