This is another post about the stupidity of Intelligent Design Creationists. Stop reading if you don't need any more convincing.
Today is Darwin Day. It's the anniversary of the birth of Charles Darwin (Feb. 12, 1809 - April 19, 1882).
This is not a happy day for the Discovery Institute so they've put up a series of posts on Evolution News & Views (sic) to discredit Darwin and "Darwinism."
To understand the core weakness of the Darwinian worldview, it is important to understand what Darwinian natural selection requires. The process will work its magic, building up functional structures in organisms, only when two very strict conditions are met: First, the structure must be adaptive—that is, helpful to the organism in flourishing in its environment—and second, there must be a continuum of structures, functional all along the way, leading from an ancestor species to the descendent.
That is, the thing we are trying to explain must in some way help the creature survive, and between the creature and the creature's ancestor there must be a gradual change, each step of which is stable and enhances fitness, or success in reproduction.
Strictly speaking, that's a reasonable explanation of Darwinism as most evolutionary biologists understand it. But here's the problem. There aren't very many evolutionary biologists who are strict Darwinists these days even though there are many who tilt strongly in that direction.
Intelligent Design Creationists are promoting a structuralist view of evolution [What is structuralism?]. The idea is that the history of life as we know it was largely preordained by the initial laws of physics and chemistry. According to this view, once life got under way it was inevitable that it would eventually evolve the way it did resulting in humans or something that closely resembles humans.
Structuralism is based on the idea of intrinsic forms that severely limit evolutionary pathways. These forms are constrained, and defined, by the physics of matter and energy. Some creationists like this idea because they believe that god created the universe and fine-tuned it for life. According to their faith, once the original laws of physics and chemistry were set up it was just a matter of time before humans evolved. These creationists can make their belief in a creator god compatible with evolution as they see it.
(Let's not forget that there are many structuralists who are legitimate scientists and some of them are atheists. Structuralism is not a creationist invention.)
The conflict between structuralists and others is brought into focus by Stephen Jay Gould writing in Wonderful Life.
The blog "Conceptual Revolutions in Science" only publishes "evidence-based, paradigm-shifting scientific news" according to their home page.
The man behind the website is Adam B. Dorfman (@DorfmanAdam). He has an MBA from my university and he currently works at a software company. Here's how he describes himself on the website.
Some of you are aware of recent attacks on Richard Dawkins. This video by Brian Dalton (Mr. Deity)1 is directed at certain people who have led the attacks. Some of them are my friends but I'm having second thoughts. They should pay close attention.
I disagree with several scientific ideas that Richard Dawkins has promoted and we have discussed these disagreements in person and on the internet. I've always found him to be polite and respectful.
Michael Denton and the Discovery Institute are promoting his new book, Evolution: Still a Theory in Crisis. I haven't yet read the book. I ordered from Amazon.ca and I won't get it until March.
The essence of the fine-tuning argument is that the basic laws of physics and chemistry are so precise that even slight changes would result in a universe where life is impossible. The focus is usually on the fundamental constants such as the speed of light and the charge on an electron. I don't know enough about physics to evaluate the argument that these are fine-tuned so I have to rely on physicists to inform me.
All available evidence suggests that we are quite likely the only advanced life form in the Milky Way galaxy. Maybe our planet harbors the only life in the entire universe.
Matthew Cobb wasn't happy with the way Denis Alexander reviewed Jerry Coyne's book. Recall that Denis Alexander is a biochemist at Cambridge University (UK) and we had a little debate a week or so ago [Is there a conflict between science and religion?]. His position is that there's no conflict between science and religion because a person who believes in god can always make their views conform to the discoveries of science. I didn't accept his premise—that gods exist—so we had a discussion about whether there's any evidence to support his belief in god.
If you believe in such a being then that conflicts with science as a way of knowing because you are believing in something without reliable evidence to support your belief. Scientists shouldn't do that and neither should any others who practice the scientific way of knowing. Denis Alexander thinks there are other, equally valid, ways of knowing but he wasn't able to offer any evidence that those other ways produce true knowledge.
Matthew Cob wrote a letter to the editor in which he asked, "I wonder if Dr Alexander, or indeed any reader, could provide an example of knowledge gained through theology, and above all tell us how they know that knowledge is true?" [see Matthew Cobb battles with the faithful over my book].
Jerry Coyne discovered a Quiz on DNA. He calls is a so-so quiz on DNA. He says that one question is really, really, dumb. I disagree, I think there are several dumb questions.
I tried it and got a score of 19/19 in just under four minutes. This is misleading since you have to get every question right before continuing on to the next question. I had to anticipate what the authors wanted in order to proceed.
Try the quiz yourself before reading any further. There are spoilers below!
The Intelligent Design Creationists are promoting Michael Denton's new book Evolution: Still a Theory in Crisis. The new buzzword is "structuralism" and it's guaranteed to impress the creationist crowd because nobody understands what it means but it sounds very "sciency" and philosophical. Also, it's an attack on "Darwinism" and anything that refutes evolution has to be good.
You can watch Michael Denton explain structuralism ... it only takes a few minutes of your time.
You are probably wondering why "Darwinism" persists after the creationists have thoroughly demonstrated that it is a failed theory. Lucky for you, the most intelligent and intellectual of all Intelligent Design Creationists, David Berlinski and Michael Denton, have gotten together to explain it in a short (15 mins) podcast.
If the most brilliant Darwin critics, like David Berlinski and Michael Denton, are right, how then does Darwinism hang on? How does a failed theory maintain its grip on our science and on our culture? Why is there a sense of stalemate? On ID the Future, we posed these questions to Dr. Berlinski and Dr. Denton.
If you are interested in the conflict between Intelligent Design and science you owe it to yourself to see/hear the best they've got on their side.
You can always dream. While the evolutionist side in the Darwin debate is long on rhetoric and insults, serious debate or dialogue is woefully rare. But imagine you had the opportunity to sit down with a thoughtful, honest, well-informed Darwinist and pose one question or challenge. What would it be?
I had the opportunity to pose that question to two of the most brilliant minds in the intelligent design community -- Michael Denton and David Berlinski. Take a well-spent 15 minutes and listen to their answers -- focusing respectively on the insect body plan and the enigma of whale evolution -- recorded as an episode of ID the Future.
Berlinski wants a detailed mathematical estimate of the number of mutations required to go from a land animal to a whale. Denton wants details on the formation of insect body plans.
It's important to note that these are questions about the history of life. You could easily answer "I don't know" to both questions and it would not affect our understanding of evolution and common descent one iota. The answers have nothing to do with "Darwinism" per se and nothing to do with evolutionary theory (which is not Darwinism).
Listen to the very best minds in the Intelligent Design Creationist community ... and weep for them. This is all they've got.
Richard Dawkins published The Selfish Gene 40 years ago and Matt Ridley notes the anniversary in a Nature article published today (Jan. 28, 2016): In retrospect: The selfish gene.
I don't remember when I first read it—probably the following year when the paperback version came out. I found it quite interesting but I was a bit put off by the emphasis on adaptation (taken from George Williams) and the idea of inclusive fitness (from W.D. Hamilton). I also didn't much like the distinction between vehicles and replicators and the idea that it was the gene, not the individual, that was the unit of selection ("selection" not "evolution").
It is finally time to return to the problem with which we started, to the tension between individual organism and gene as rival candidates for the central role in natural selection...One way of sorting this whole matter out is to use the terms ‘replicator’ and ‘vehicle’. The fundamental units of natural selection, the basic things that survive or fail to survive, that form lineages of identical copies with occasional random mutations, are called replicators. DNA molecules are replicators. They generally, for reasons that we shall come to, gang together into large communal survival machines or ‘vehicles’.
Currently there are two distinct views on the origin of life. The majority of scientists think that life arose in a prebiotic soup of complex organic molecules. Most of them think this "warm little pond" was the ocean (!) and most of them have bought into the stories about asteroids and comets delivering complex organic molecules to create a soup of amino acids and sugars. Presumably, all the earliest forms of life had to do was to join together the amino acids to make proteins and hook up the nucleotides to make RNA. The energy for these reactions was derived from breaking down all the glucose in the sweet ocean.
