Genetics paper retracted: “Some other mechanism” is responsible for genetic mutations

In “Genetics Paper Retracted: Due to statistical errors, a Science paper claiming that mutation is responsible for genetic variation is retracted” (The Scientist September 2, 2011), Jessica P. Johnson reports, A May 2010 Science paper showing that the most genetically fit cow-pea weevils have fewer deleterious genetic mutations in their genomes than their less fit Read More…

A reason captured in photos: Here, Barry Arrington notes, “Natural Selection Defies the Odds,” As in Recently the management of a casino hired Professor Hannum to investigate a roulette player whom they suspected might be cheating. The house has a huge mathematical advantage in roulette, which is why the casino suspected something other than random Read More…

No evidence that there is enough time for evolution

No evidence that there is enough time for evolution[*] Lee M Spetner Redoxia Israel, Ltd. 27 Hakablan St., Jerusalem, Israel Abstract: A recent attempt was made to resolve the heretofore unaddressed issue of the estimated time for evolution, concluding that there was plenty of time. This would have been a very significant result had it Read More…

The Nature of Nature — sticky

THE NATURE OF NATURE is now finally out and widely available. If you haven’t bought it yet, let me suggest Amazon.com, which is selling it for $17.94, which is an incredible deal for a 7″x10″ 1000-page book with, for most of us, no tax and no shipping charge (it costs over $10 to ship this Read More…

Natural Selection Redux

PaV’s recent post Darwinn Step Aside – Survival of the ‘Quickest’ got me thinking again about natural selection and the role it supposedly played in evolution. The conventional wisdom among Darwinists, including Darwin himself, is that NS is a mechanism. The very title of Darwin’s famous tome suggests as much – On The Origin of Read More…

Lenski – “Mr. E. Coli” – thinks evolution has a purpose?

Lenski’s the guy who studied all those generations of E. Coli bacteria, and discovered that over many thousands of generations, there were very few beneficial mutations. (Darwinism depends, not on mutations as such but on mutations that benefit the organism.) Recently, his work was the subject of an item, “Evolvability, observed” by Jef Akst (The Read More…

Human evolution: Natural selection less important force, researchers say

From Tina Hesman Saey, “Helpful Mutations Didn’t Sweep Through Early Humans”, Wired Science (February 18, 2011) we learn Humans probably didn’t get swept up in evolution.Scientists have favored a model of evolution in which beneficial gene mutations quickly and dramatically sweep through a population due to the evolutionary advantages they confer. Such mutations would become 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 Read More…

The late Stephen J.

It is, indeed, a wonderful life.” (Gould, Stephen J. [Professor of Zoology and Geology, Harvard University], “Wonderful Life: The Burgess Shale Read More…

Is nature really a struggle in which natural selection is the key factor?

British physicist David Tyler comments: In a perceptive essay, Daniel Todes focuses attention on the reactions of Russian biologists to Darwin’s writings. Many of these naturalists “were evolutionists before 1859”, so they did not dissent from common ancestry. However, their experiences of the living world were quite different from Darwin and Wallace, who drew their Read More…
