I have read and listened and watched a lot of material on intelligent design, but I have never seen so much value packed into such a short lecture. I really hope you’ll watch this and that it’s helpful to you.
the big question when discussing the origin of life: where did the information in living systems come from?
Until 530 million years ago, the oceans were largely devoid of life
In a 10 million year period, many new forms of animal life emerged
New biological forms of life require new information
the discovery of DNA shows that living systems work because cells have information that allows them to build the components of molecular machines: cell types, proteins, etc.
can random mutation and natural selection create new functional information?
normally, random mutations tend to degrade the functionality of information, e.g. – randomly changing symbols in an applications code does not usually introduce useful new functions, it usually renders what is there non-functional
the majority of possible sequences will NOT have functions, so random mutations will more likely give you non-functional code, rather than functional code
example: a bicycle lock with 4 numbers has many possible sequences for the 4 numbers, and only one of them has unlock functionality, the rest have no functionality
if you have lots of time, then you might be able to guess the combination, but if the lock as has 10 billion numbers, and only one combination that unlocks, you can spend your whole life trying to unlock it and won’t succeed
how likely is it to arrive at a functional protein or gene by chance? Is it more like the 4-dial lock (can be done with lots of time) or the 10 billion dial lock (amount of time required exceeds the time available)?
the probability is LOW because there is only one sequence of numbers that has unlock function
consider a short protein of 150 amino acids has 10 to the 195th power possible sequences
if many of these sequences of amino acides had biological function, then it might be easier to get to one by random mutation and selection than it is with a lock that only unlocks for ONE sequence
how many of the possible sequences have biological function?
Thanks to research done by Douglas Axe, we now know that the number of functional amino acid sequences for even a short protein is incredibly small…
Axe found that the odds of getting a functional sequence of amino acids that will fold and have biological function is 1 in 10 to the 77th power
Is that number too improbable to reach by chance? well, there are 10 to 65th atoms in the entire Milky Way galaxy… so yes, this is a very improbable outcome
can random genetic mutations search through all the sequences in order to find the one in 10 to the 77th power one that has biological function? It depends on how much guessers we have and how many guesses we get in the time available
even with the entire 3.5 billion year history of life on Earth, only about 10 to the 40th organisms have ever lived, which far smaller fraction of the 10 to the 77th total sequences
even with a very fast mutation rate, you would not be able to reach a functional protein even with all that time, and even with all those organisms
I was once having a discussion with a woman about the research that Axe did at the Cambridge University lab. He published four articles in the Journal of Molecular Biology. I held out one of the papers to her and showed her the numbers. She said over and over “I hate the Discovery Institute! I hate the Discovery Institute!” Well, yeah, but you can’t make the Journal of Molecular Biology go away with hating the Discovery Institute. JMB is peer-reviewed, and this was experimental evidence – not a theory, not a hypothesis.
We have been blessed by the Creator and Designer of the universe in this time and place with overwhelming evidence – an abundance of riches. For those who have an open mind, this is what you’ve been waiting for to make your decision. For the naturalists who struggle so mightily to block out the progress of experimental science, they’ll need to shout louder and shut their eyes tighter and push harder to block their ears. Maybe if they keep screaming “Star Trek” and “Star Wars” over and over to themselves, they will be able to ignore the real science a little longer.
(Re-posting this for those who missed it the first time around)
This is a must-see / must-hear conversation. Famous conservative Ben Shapiro discusses evolution and intelligent design with Dr. Stephen C. Meyer, author of “Signature in the Cell” (origin of life) and “Darwin’s Doubt” (fossil record). These are the two best books on intelligent design. Their conversation covers the most important issues in the origins debate.
So to start, here’s the full video:
Someone actually put out an outline on Youtube, with a time-based index, so I’ll just steal that as a base, and add to it:
1:34What is your scientific background? Science undergraduate degree, professional geologist, later did a PhD in philosophy of science from Cambridge University.
2:39What is the difference between intelligent design and creationism? Creationism starts from the Bible and posits a shorter history of the universe. ID starts from the data of the natural world and is neutral about the age of the Earth / universe. Meyer accepts the old-Earth.
3:36 How is Intelligent Design a scientific theory? The discovery of DNA reveals that code is central to living systems. Intelligent design uses the method of “inference to the best explanation” in order to argue that the best explanation for the code is an intelligent agent.
6:10What evidence would have to arise to make Intelligent Design Falsifiable? If a naturalistic mechanism was discovered that could produce biological information using the probabilistic resources of the universe, and the time available, then intelligent design would be falsified.
7:26 Is religion separate from science or intertwined within it? There are three views: science is totally separate from religion, science is in total conflict with religion, science and religion agree on some issues, e.g. – the origin of the universe and Genesis 1:1. There are areas where science and religion overlap.
9:55 Why are the most prominent Darwinians also militant atheists? Evolution is a theory that tries to explain nature using naturalistic mechanisms, so it is compatible with atheism.
10:45What does the theory of evolution say? The term evolution has multiple meanings, and should be defined before discussions. It can refer to change over time. It can refer to animals changing slightly to adapt to enviromental changes. It can refer to the idea that all animals evolved from simpler life forms, and that there is a tree of life showing how different types of organisms share common ancestors. And it can refer to the idea that purely undirected processes can explain the history of life using purely materialistic forces. It’s that final view that intelligent design challenges.
13:15Where is the discontinuity in naturalistic processes in the development of life? The first discontinuity is the origin of simple life from non-living components. The second discontinuity is the sudden appearance of different body plans in a very narrow window of time in the Cambrian era.
15:42 Why does information theory suggest that code requires some sort of designer? DNA is a true information-bearing system identical to the software in computers, e.g. – operating system, applications.
19:45Can information be created by random mutation, and favorable mutations preserved by natural selection? Just as in software code, instructions must be added in order to develop new functionality. Random additions of characters will almost always degrade biological function. The number of possible sequences that do nothing useful is vastly higher than the number of sequences that perform biological functions. Doug Axe did research on this at Cambridge University, and he found that the number of functional sequences of amino acids is 1 in 10 to the 77th power. Given the probabilistic resources (replicating organisms)and the time available, it is extremely unlikely to find sequences that have functional information by chance.
25:05 What about Stephen Jay Gould’s model of punctuated equilibrium – doesn’t it explain the sudden jumps in information? Gould’s mechanism is accurate according to the fossil record, which shows a lot of jumps. But he did not have a naturalistic explanation for sudden jumps in biological function. Darwinian mechanisms work slowly and would (in theory) produce different body plans gradually. But this is not what the fossil record shows.
27:22 What is the mechanism for injecting information in the theory of intelligent design? The information comes in from an intelligence when new major body plans appear, and minor variations within types could be explained by evolution.
29:25Does the Miller-Urey experiment provide a naturalistic explanation for the building blocks necessary for the origin of life? The MU experiment only produced a few types of amino acids, it doesn’t say anything about how to sequence the amino acids in order to form protein folds that can perform biological functions. The MU experiment also pre-supposes conditions on the early Earth (reducing gases) that do not match what was there (oxidyzing or neutral gases).
32:00 Is the RNA world hypothesis is a good explanation for the origin of life? Evolution requires that replication already be in place, because evolution assumes that mutations appear during the replication. The RNA world hypothesis suggests that sequences contain information, but also catalyze origin of life chemistry. The problem with RNA world is that it starts with self-replicating systems. And those replicating systems require the scientist to inject information into the system to get even the simplest replication started.
34:56 How do scientists respond to the critiques of Darwinism proposed by intelligent design advocates? By and large, they accept them. They think that mutation and selection works once living systems are in place, but they realize it has no explanation for the origin of life or the sudden origin of body plans. (Tells about the conference of the Royal Society, where problems with Darwinian mechanisms were discussed, and the 2003 MIT Press book by Muller and Newman).
37:16 Why do people hold to Darwinian evolution in the face of these problems? Many scientists presuppose methodological naturalism, which requires that any explanation for the origin of life and the origin of major body plans involve materialist explanations only. No intelligent agents are allowed. The problems occur when assumption of naturalism causes scientists to propose incorrect explanations for what we observe in nature. It’s also not clear how naturalistic mechanisms could produce organisms who are capable of reason and free will.
40:43 Does naturalistic evolution have an answer for conscious minds, reasoning, free will? No, consider the work of atheist scholar Thomas Nagel, who argues in his book “Mind and Cosmos” (Oxford University Press 2012) that the existence of mind is a disproof of the neo-Darwinian explanation for life. Darwinism stops us from accepting the reality of minds.
42:06 So do naturalistic evolutionists have to explain away the mind as an illusion? First, we humans have immediate experience of consciousness, reason and free will. Second, our whole legal system is based on the idea free will, because you can’t hold someone guilty unless they chose to do something they knew was wrong. Third, we have an epidemic of suicide among young people. This is caused by a crisis of meaning. Intelligent design opens up the possibility of their being a mind behind the universe, who we could have a relationships with.
44:53 Why aren’t schools allowed to be honest about the problems with neo-Darwinian evolution? The intellignt design view is to that teachers should be allowed to teach all the vidence for Darwinian evolution, and also discuss some of the problems with the theory. Students learning science should not be told that everything is solved. Students learn science better when they are presented with peer-reviewed evidence for and against a theory, rather than being indoctrinated.
47:37 Is intelligent design theory connected to God? Intelligent design infers from the information content in nature that a mind with capabilities like ours injected information into living systems. Intelligent design is agnostic about the designer, because in principle, embodied or unembodied agents could inject information into living systems. Intelligent design is friendly to theism, because theists will immediately identify the mind as God. Furthermore, the fine-tuning in the initial conditions of the universe is another intelligent design argument. In that case, since the design occurs at the beginning of the universe, the intelligent agent acting prior to the creation of the universe would have to be supernatural, i.e. – God.
50:53 Can naturalists say that the imposition of “function” on a sequence is arbitrary, in the same way that the English language is arbitrary? This won’t work, because biological function is not arbitrary in the same way as language. Biological function is not arbitrary, because sequences can be tested for function objectively by observing whether sequences can perform functions necessary for life, e.g. – replication.
52:43 Doesn’t the multiverse explain away the improbabilities of the fine-tuning, the origin of life, and the development of life? No, because all models of the multiverse require fine-tuning in the mechanism that generates the different universes.
55:42 What about cosmological models that eliminate the beginning of the universe? The standard Big Bang model and the inflationary model both posit a beginning of the universe. There is also the Borde-Guth-Vilenkin theory which proves that any universe that is expanding requires a beginning. The only chance for naturalists is quantum cosmologies, but this doesn’t work because 1) it requires an abstract reality of mathematics to actualize the physical universe, but this presupposes a mind. 2) The model requires an earlier input of information, which can only have come from a mind.
If you listen to this lecture, or watch the video, and you enjoyed it, then please share. If you have questions, I can try to answer them for you – just leave your question in the comments, or shoot me an e-mail, or message me from the blog’s Facebook page, or direct message me on Twitter. I’ve invested a lot of time in this, and have been studying intelligent design since the late 1990s.
I highly recommend watching the lecture, and looking at the slides. The quality of the video and the content is first class. There is some Q&A (9 minutes) at the end of the lecture.
intelligent design is concerned with measuring the information-creating capabilities of natural forces like mutation and selection
Darwinists think that random mutations and natural selection can explain the origin and diversification of living systems
Darwinian mechanisms are capable of explaining small-scale adaptive changes within types of organisms
but there is skepticism, even among naturalists, that Darwinian mechanisms can explain the origin of animal designs
even if you concede that Darwinism can account for all of the basic animal body plans, there is still the problem of life’s origin
can Darwinian mechanisms explain the origin of the first life? Is there a good naturalistic hypothesis to explain it?
there are at least two places in the history of life where new information is needed: origin of life, and Cambrian explosion
overview of the structure of DNA and protein synthesis (he has helpful pictures and he uses the snap lock blocks, too)
the DNA molecule is composed of a sequence of bases that code for proteins, and the sequence is carefully selected to have biological function
meaningful sequences of things like computer code, English sentences, etc. require an adequate cause
it is very hard to arrive at a meaningful sequence of a non-trivial length by randomly picking symbols/letters
although any random sequence of letters is improbable, the vast majority of sequences are gibberish/non-compiling code
similarly, most random sequences of amino acids are lab-proven (Doug Axe’s work) to be non-functional gibberish
the research showing this was conducted at Cambridge University and published in the Journal of Molecular Biology
so, random mutation cannot explain the origin of the first living cell
however, even natural selection coupled with random mutation cannot explain the first living cell
there must already be replication in order for mutation and selection to work, so they can’t explain the first replicator
but the origin of life is the origin of the first replicator – there is no replication prior to the first replicator
the information in the first replicator cannot be explained by law, such as by chemical bonding affinities
the amino acids are attached like magnetic letters on a refrigerator
the magnetic force sticks the letters ON the fridge, but they don’t determine the specific sequence of the letters
if laws did determine the sequence of letters, then the sequences would be repetitive
the three materialist explanations – chance alone, chance and law, law alone – are not adequate to explain the effect
the best explanation is that an intelligent cause is responsible for the biological explanation in the first replicator
we know that intelligent causes can produce functional sequences of information, e.g. – English, Java code
the structure and design of DNA matches up nicely with the design patterns used by software engineers (like WK!)
There are some very good tips in this lecture so that you will be able to explain intelligent design to others in simple ways, using everyday household items and children’s toys to symbolize the amino acids, proteins, sugar phosphate backbones, etc.
Proteins are constructed from a sequence of amino acids:
Proteins sticking onto the double helix structure of DNA:
I highly, highly recommend this lecture. You will be delighted and you will learn something.
Here is an article that gives a general overview of how intelligent design challenges. If you want to read something more detailed about the material that he is covering in the lecture above related to the origin of life, there is a pretty good article here.
There is a good breakdown of some of the slides with helpful flow charts here on Uncommon Descent.
