The host of the Cross Examined radio show Dr. Frank Turek talks with Stephen C. Meyer and Doug Axe about a recent conference of Royal Society scientists discussing the problems with the theory of macro-evolution.
the main topic was whether naturalistic mechanisms can produce new body plans and new organ types
no one disputes micro-evolution: beaks changing size, antibiotic resistance
many of the naturalistic scientists admitted the problems with current naturalistic theories, but they don’t want to embrace the need for a designer
none of the proposals that were debated solved the real problems with macro-evolution
Problem #1: the sudden origin of body plans in the fossil record
Problem #2: the origin of information (e.g. – in protein molecule)
Problem #3: need for favorable early mutations (for body plans)
Problem #4: the problem of epigenetics
Problem #5: the universality of the design intuition
Some of these problems have actually gotten worse for naturalistic evolution as our scientific knowledge has grown.
If you want the two best books on intelligent design, get Dr. Meyer’s “Signature in the Cell” and “Darwin’s Doubt”. I should note that Dr. Meyer is not a young Earth creationist, and has defended the Big Bang cosmology as a solid evidence for a Creator of the universe. Being in favor of an old universe and an old Earth is compatible with being opposed to evolution – because of scientific reasons.
Charles Darwin thought that “by far the strongest” evidence that humans and fish are descended from a common ancestor was the striking similarity of their early embryos. According to Darwin, the fact that “the embryos of the most distinct species belonging to the same class are closely similar, but become, when fully developed, widely dissimilar… reveals community of descent.” 2 To illustrate this, German Darwinist Ernst Haeckel made some drawings in the 1860s to show that the embryos of vertebrates (fish, amphibians, reptiles, birds and mammals) look almost identical in their earliest stages.
But Haeckel faked his drawings. Not only do they distort vertebrate embryos by making them appear more similar than they really are (in a way that Stephen Jay Gould wrote “can only be called fraudulent” 3), but they also omit classes and stages that do not fit Darwin’s theory. Most significantly, Haeckel omitted the earliest stages, in which vertebrate embryos are strikingly different from each other. The stage he portrayed as the first is actually midway through development. Yet according to Darwin’s logic, early dis-similarities do not provide evidence for common ancestry.
Haeckel used his faked drawings to support not only Darwinian evolution, but also his own “Biogenetic Law,” which stated that embryos pass through the adult stages of their ancestors in the process of development.
…Haeckel’s drawings were exposed as fakes by his own contemporaries, and his Biogenetic Law was thoroughly discredited by 20th century biologists. It is now generally acknowledged that early embryos never resemble the adults of their supposed ancestors. A modern version of recapitulation claims that early embryos resemble the embryos of their ancestors, but since fossil embryos are extremely rare, this claim is little more than speculation based on the assumption that Darwin’s theory is true.
Now the standard response from Darwinists: no textbooks are still using the fraudulent embryo images.
You can see the actual faked pictures from the modern textbooks here. These textbooks were being produced as late as 2004, even though the fraud was detected in the 1800s! Is this the vaunted self-correction of science, or science being twisted to support social and political goals?
And this excerpt from that article is interesting:
Some Darwinists continue to deny that there has been any misuse of Haeckel in recent times. If that is the case, why did Stephen Jay Gould attack how textbooks use Haeckel in 2000? Gould wrote: “We should… not be surprised that Haeckel’s drawings entered nineteenth-century textbooks. But we do, I think, have the right to be both astonished and ashamed by the century of mindless recycling that has led to the persistence of these drawings in a large number, if not a majority, of modern textbooks!” (emphasis added) Similarly, in 1997, the leading embryologist Michael K. Richardson lamented in the journal Anatomy and Embyology that “Another point to emerge from this study is the considerable inaccuracy of Haeckel’s famous figures. These drawings are still widely reproduced in textbooks and review articles, and continue to exert a significant influence on the development of ideas in this field.” (emphases added)
Here is a link to the peer-reviewed journal Science, where there is an article talking about the fraudulent embryo drawings. Yes – the drawings really are fraudulent.
And finally, Casey Luskin has a new post up at Evolution News that lists all the textbooks that contain the fraudulent drawings. One is dated 2013! The drawings just keep getting recycled over and over as a “proof” of evolution.
Michael Behe and Keith Fox debate evolution and intelligent design. (See below for link to video)
Michael Behe is professor of biochemistry at Lehigh University, Pennsylvania and the founder of the modern Intelligent Design movement. His book “Darwin’s Black Box” ignited the controversy 14 years ago when it claimed that certain molecular machines and biological processes are “irreducibly complex” and cannot be explained by Darwinian evolution.
Keith Fox is Professor of biochemistry at the University of Southampton and chairman of Christians in Science. As a theistic evolutionist he believes that Evolution is the best explanation going for the complexity we see and that ID is a blind scientific alley and theologically unappealing to boot.
They debate whether micromachines in the cell such as the “bacterial flagellum” could have evolved by a Darwinian process of evolution. When inference to design is and isn’t acceptable in science. Whether random mutation can mathematically stack up to complex life, and whether God is reduced to a divine “tinkerer” by ID.
Here’s the debate:
Note: the following debate summary is rated “S” for Snarky. Reader discretion is advised.
ID is not Biblical creationism
ID is not religion
ID is a scientific research program
People refuse to discuss ID because of personal philosophical assumptions
ID is like the Big Bang – it is based on evidence, but it has broad religious implications
ID is not Biblical creationism, but it isn’t science
ID is compatible with common descent
ID is only opposed to unplanned, unguided evolution (Darwinism)
ID is not necessarily opposed to long periods of time
Behe’s first book – the bacterial flagellum
Here are a couple of papers that show how parts of the flagellum evolved
They are possible pathways
No, those are studies that show that there are similarities between bacterial flagella in multiple organisms
Similarities of proteins between different organisms do not necessarily imply a developmental pathway
The problem of having the instructions to BUILD the flagellum still remains
Maybe parts of the flagellum had other functions before they were used in the flagellum
Maybe you can use the parts of the flagellum for other purposes
Maybe, one can imagine, it’s possible that!
No, parts have to be modified and re-purposed in order to be used for other functions
But maybe the proteins can be used in other systems for other things
I re-purpose parts from of designed things to other purposes in my house when I do maintenance
Uh, yeah – but aren’t you an intelligent designer? What does your home maintenance have to do with Darwinian evolution?
Is ID another God-of-the-gaps argument?
Well consider the Big Bang… there was a build-up of scientific evidence for that theory
Just because a theory has religious implications, doesn’t mean that it isn’t true
You really have to look at the specific evidence for a theory, and not decide in advance
Keith Fox: (I’m paraphrasing/inventing/mocking from now on)
But the Big Bang is based on discoveries, and intelligent design is based on gaps in our scientific knowledge
What if I did have evidence of a step by step pathway (which I don’t right now)? Then I would win the argument – what would you do then?
Well, if tomorrow you do manage to find expiremental evidence of a pathway, which you don’t have today, then I would be wrong
ID is falsifiable by experimental evidence
But what about your your view? Is that falsifiable by experimental evidence?
Lenski has presided over 50,000 generations, (millions of years of evolution)
The bacterium did evolve and they did get better but not by evolving features, but by disabling features
But those are just LAB EXPERIMENTS! What do lab experiments prove?
What if? What if? What if? You don’t know, it happened so long ago, and you weren’t there! You weren’t there!
(clutches Flying Spaghetti Monster idol tighter and sobs pitifully)
See, the thing is that I have actual experiements, and here’s some more evidence that just got published last week
So I’ve got evidence and then some more evidence and them some other evidence – experimental evidence
And all the evidence shows that adaptation is done losing traits not by gaining traits
And the published observations are what we see in nature as well
But doesn’t Darwinism explain some things that we observe?
Well, I am not saying that micro-evolution doesn’t explain some things – it explains bacterial resistance, and other micro-evolution
it just doesn’t explain macro-evolution, and that’s what the experiments show
But ID is a science stopper! It stops science! You can’t produce experimental evidence to falsify Darwinism – that would stop science!
Well, you have to understand that the Big Bang postulated a non-material cause to the entire physical universe and yet the experimental evidence was allowed to stand because it was testable and verifiable evidence, even if the theory does have religious implications
All explanations in science are design to settle a question and it stops rival explanations that are not as good at explaining the observations
Finding the best explanation stops further study because it is better than rival explanations
Well you have to come up with a materialist explanation because that’s the only kind that a functional atheist like me will allow
Well, what if the best explanation for an observed effect in nature is non-material, as with the Big Bang?
But I have to have a material explanation because I am a functional atheist! (i.e. – a theistic evolutionist = functional atheist)
Well what about the cosmic fine-tuning argument? Do you accept that?
That’s an inference to design based on the latest scientific discoveries
Well I do accept that argument, but I don’t accept design in biology
When you apply it to biology, somehow it’s bad and you can’t do that or you losing research money and get fired
Anyway, your argument is based on a gap in our current knowledge
No, back in Darwin’s time we had a gap in our knowledge – we didn’t know what the cell was – we thought it was jello
Now, we know what the cell is really like, it’s irreducibly complex, and you can’t build up those molecular machines in a step-wise manner
The inference to design is based on the progress of science revealing the increasing levels of complexity
In experiments, Darwinian mechanisms cannot build anything useful, instead genes are disabled or dropped
You guys don’t have the evidence to prove your view that naturalistic mechanisms can do the creating
You keep issuing promissory notes
Well, you’re just seeing design subjectively, because you are a non-scientist
I’m being objective when I tell you that we will discover a materialist explanation later on – really really soon now, maybe even tomorrow, yeah
You won’t accept my speculations and you insist on these published experiments
You’re subjective and I’m objective
Just give me more research money so I can hide the decline better
Uh, you’re the one who is subjective – I cited evidence, and you are the one who is speculating
You have arguments from credulity, and I’ve got the lab experiments
You refuse to be skeptical, I am the one who is being skeptical
Maybe, maybe, maybe! Maybe tomorrow! Maybe in a parallel universe! Maybe aliens from Planet 9 from Outer Space!
Who knows! I certainly don’t know! And that somehow means you don’t know either! See?
Well, to prove me wrong, go into the lab, and run experiments and evolve some new genes (using Darwinian mechanisms) that have new useful functionality
Are there limits to what evolution can do?
You need multiple changes in the genome to get a new helpful feature (let’s say two specific mutations)
One specific change is possible
the odds are against getting multiple beneficial changes are really really small – you need two SPECIFIC changes to occur in order
Well, lots of things are really unlikely – any permutation of dice rolls is as unlikely as any other
Well, we are talking about TWO SPECIFIC mutations that are needed to get a beneficial function – lots of other mutations are possible, but we are looking for a specific outcome that requires two SPECIFIC mutations out of the whole genome
You aren’t going to get useful outcomes unless you direct the mutations
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.
Here’s a paper published in the prestigious peer-reviewed science journal Nature, entitled “The oxidation state of Hadean magmas and implications for early Earth’s atmosphere”. This paper is significant because it undermines naturalistic scenarios for the origin of life.
A recent Nature publication reports a new technique for measuring the oxygen levels in Earth’s atmosphere some 4.4 billion years ago. The authors found that by studying cerium oxidation states in zircon, a compound formed from volcanic magma, they could ascertain the oxidation levels in the early earth. Their findings suggest that the early Earth’s oxygen levels were very close to current levels.
[…]Miller and Urey conducted experiments to show that under certain atmospheric conditions and with the right kind of electrical charge, several amino acids could form from inorganic compounds such as methane, ammonia, and water. Several experiments have been done using various inorganic starting materials, all yielding a few amino acids; however, one key aspect of all of these experiments was the lack of oxygen.
If the atmosphere has oxygen (or other oxidants) in it, then it is an oxidizing atmosphere. If the atmosphere lacks oxygen, then it is either inert or a reducing atmosphere. Think of a metal that has been left outside, maybe a piece of iron. That metal will eventually rust. Rusting is the result of the metal being oxidized. With organic reactions, such as the ones that produce amino acids, it is very important that no oxygen be present, or it will quench the reaction. Scientists, therefore, concluded that the early Earth must have been a reducing environment when life first formed (or the building blocks of life first formed) because that was the best environment for producing amino acids. The atmosphere eventually accumulated oxygen, but life did not form in an oxidative environment.
The problem with this hypothesis is that it is based on the assumption that organic life must have formed from inorganic materials. That is why the early Earth must have been a reducing atmosphere. Research has been accumulating for more than thirty years, however, suggesting that the early Earth likely did have oxygen present.
[…]Their findings not only showed that oxygen was present in the early Earth atmosphere, something that has been shown in other studies, but that oxygen was present as early as 4.4 billion years ago. This takes the window of time available for life to have begun, by an origin-of-life scenario like the RNA-first world, and reduces it to an incredibly short amount of time. Several factors need to coincide in order for nucleotides or amino acids to form from purely naturalistic circumstances (chance and chemistry). The specific conditions required already made purely naturalist origin-of-life scenarios highly unlikely. Drastically reducing the amount of time available, adding that to the other conditions needing to be fulfilled, makes the RNA world hypothesis or a Miller-Urey-like synthesis of amino acids simply impossible.
So here’s where we stand. If you are a materialist, then you need a reducing environment on the early Earth in order to get organic building blocks (amino acids) from inorganic materials. However, the production of these organic building blocks (amino acids) requires that the early Earth atmosphere be oxygen-free. And the problem with this new research, which confirms previous research, is that the early Earth contained huge amounts of oxygen – the same amount of oxygen as we have today. This is lethal to naturalistic scenarios for creating the building blocks of life on the Earth’s surface.
The “origin of life” (OOL) is best described as the chemical and physical processes that brought into existence the first self-replicating molecule. It differs from the “evolution of life” because Darwinian evolution employs mutation and natural selection to change organisms, which requires reproduction. Since there was no reproduction before the first life, no “mutation – selection” mechanism was operating to build complexity. Hence, OOL theories cannot rely upon natural selection to increase complexity and must create the first life using only the laws of chemistry and physics.
There are so many problems with purely natural explanations for the chemical origin of life on earth that many scientists have already abandoned all hopes that life had a natural origin on earth. Skeptical scientists include Francis Crick (solved the 3-dimensional structure of DNA) and Fred Hoyle (famous British cosmologist and mathematician), who, in an attempt to retain their atheistic worldviews, then propose outrageously untestable cosmological models or easily falsifiable extra-terrestrial-origin-of-life / panspermia scenarios which still do not account for the natural origin of life. So drastic is the evidence that Scientific American editor John Horgan wrote, “[i]f I were a creationist, I would cease attacking the theory of evolution … and focus instead on the origin of life. This is by far the weakest strut of the chassis of modern biology.”3
The article goes over the standard problems with naturalistic scenarios of the origin of life: wrong atmosphere, harmful UV radiation, interfering cross-reactions, oxygen levels, meteorite impacts, chirality, etc.
Most people who are talking about intelligent design at the origin of life talk about the information problem – how do you get the amino acids to form proteins and how do you get nucleotide bases to code for amino acids? But the starting point for solving the sequencing problem is the construction of the amino acids – there has to be a plausible naturalistic scenario to form them.
