Biomathematics: Sixth great revolution in science?

According to Ian Stewart (“The formula of life,” New Statesman, 27 April 2011),

Biology is undergoing a renaissance as scientists apply mathematical ideas to old theory. Welcome to the discipline of biomathematics, with its visions of spherical cows, football-shaped viruses and equations that can predict the pattern of a zebra’s stripes.

Biology used to be about plants, animals and insects, but five great revolutions have changed the way that scientists think about life: the invention of the microscope, the systematic classification of the planet’s living creatures, evolution, the discovery of the gene and the structure of DNA. Now, a sixth is on its way – mathematics.

What will this mean? That math will get upgraded from a “bit player” to “centre stage” in biology, says Stewart: Read More ›

PZ Myers “repositioning” himself? Also, the French discover Yankee Darwinists

Vincent Fleury

And the French react the way they do to British cuisine

New Zealand journalist Suzan Mazur interviews French scientist Vincent Fleury, who investigates origin of form with experiments involving cellular flow. The topic of P.Z. Myers, dean of American Darwinism and darling of Nature, came up:

Suzan Mazur: PZ Myers, the Howard Stern of sciencebloggers, recently reviewed your paper Clarifying tetrapod embryogenesis, a physicist’s point of view, which was published in The European Physical Journal: Applied Physics. It appears Myers is increasingly doing a pas de deux with the physical approach to evolutionary science, trying to reposition himself now that a paradigm shift is afoot. In essence, so he can maybe say, well I knew it all the time.

[ … ]

Vincent Fleury: There are several issues. First of all, it’s the style of the man. When you read his blog, you read things like I’m a professor and if I had a student, I would have asked him to rewrite the paper in this and that way. Who is this man?

Suzan Mazur: Think Animal House and pimply adolescence. His audience, incidentally, includes some prominent evolutionary scientists — one of whom commented on your paper in the Pharyngula blog.

Vincent Fleury: Myers’ blog is constructed in a certain way. He writes reviews that are not that bad but then he opens it up to his hounds, half of whom are mad. Crazed! They finish the job. Read More ›

But then, if you shoot yourself repeatedly in the foot, why do you think you SHOULD get cheap health insurance?

Reading further into Suzan Mazur’s Altenberg 16: An Expose of the Evolution Industry, I learned something interesting: Scientists and philosophers who explore self-organization in evolution  also battle the armies of Fortress Tenure (trolls commanded by tax burdens). Mazur notes that zoologist and natural philosopher Stan Salthe, visiting scholar at Binghamton University says “his skepticism about natural selection has made him “poison” in some science circles.” He’s not by any means the only one whose name comes up. Materialist atheist philosopher Jerry Fodor (MIT) joked that he was in the Witness Protection Program for his skepticism of evolutionary psychology.[!] Meanwhile, Stuart Newman of New York Medical College warns, Unless the discourse around evolution is opened up to scientific perspectives beyond Darwinism, the Read More ›

The Limits of Self Organisation

I’m writing to tell people about a paper of mine that was published in Synthese last month, titled:  “Self-organisation in dynamical systems: a limiting result”.  While the paper doesn’t address intelligent design as such, it indirectly establishes strict limits to what such evolutionary mechanisms as natural selection can accomplish.  In particular, it shows that physical laws, operating on an initially random arrangement of matter, cannot produce complex objects with any reasonable chance in any reasonable time.

The argument is based on a number of original mathematical theorems that are proved in the paper.  A less technical presentation of the argument is however given below.

I didn’t know about this conference – and it features Michael Denton too

Tom Heneghan advises, “As Darwin Year ends, some seek to go ‘beyond Darwin,’” (Reuters Faith World: Religion and Ethics, December 14, 2009).

So I was intrigued by a conference held at UNESCO here in Paris recently about scientists who believe in evolution but want to go “beyond Darwin.” Organised by French philosopher of science Jean Staune, its speakers argued that Darwin could not explain underlying order and patterns found in nature. “We have to differentiate between evolution and Darwinism,” said Jean Staune, author of the new book Au-dela de Darwin (Beyond Darwin). “Of course there is adaptation. But like physics and chemistry, biology is also subject to its own laws.”

Well, say it in French or in English, but just say it out loud: “le darwinisme, c’est incroyable;” “Darwinism is unbelievable.”

Still, here is the story in a nutshell: Once a person claims to me that the chimp in the zoo is 99% identical to one of my grandkids, I know I am dealing with an unbelievable belief. Just how to deal with it is a difficult question, especially if the belief is government-funded and supported by all the right people (who don’t think I should have grandkids anyway).

Michael Denton, a geneticist with New Zealand’s University of Otago, said Darwinian “functionalists” believed life forms simply adapted to the outside world while his “structuralist” view also saw an internal logic driving this evolution down certain paths. His view, which he called “extraordinarily foreign to modern biology,” explained why many animals developed “camera eyes” like human ones and why proteins, one of the building blocks of life, fold into structures unchanged for three billion years.

Biosemiotics and Intelligent Design

Semiotix – Stephen Pain The distinction between “theorising” and “belief” is extremely important because our attitude differs towards them. In a theory the reified concept of the sign does not have an ontological status but an epistemological one. While in belief, the concept has often a clear ontological one. Uexküll believed in his concept of the Bauplan in the same way as Bergson believed in the vital force. The concept of a plan is of course no different from the creationist’s concept of “intelligent design”. Any usage of the Bauplan is further complicated by its ideological usage in The Biological State, Uexküll‘s template for the German State, one that was anti-democratic and in many instances attractive to the Nazi of Read More ›
