in Pharyngula [Evolution, development, and random biological ejaculations from a godless liberal] PZ Myers writes about a recent press release from Princeton:
“Unfortunately, the puff piece writer and the scientists involved seem incapable of actually explaining what they found, which makes me extremely suspicious.
….
Anyway, I’ll be looking for the paper. My bet would be that it says nothing like the claims made for it by the press release, or that it will be an embarrassing error of interpretation by the authors.:
The target of his disbelief was also discussed in a recent thread on friendfeed:

Princeton Team Challenges Darwin: Evolution Not Random?
3 hours ago – via Bookmarklet
I can’t really understand what their theory actually is, but I’m skeptical that it
presents a challenge to our understanding of the role of randomness is evolution.
Randomness is just supposed to describe some of the ways DNA changes over time,
not the way the organism works. – j1m

I had asked Jonathan Eisen about this http://phylogenomics.blogspot…., who pointed me
to the discussion at Pharyngula http://scienceblogs.com/pharyn… The consensus appears
to be that it’s unsupported hype. – Ruchira S. Datta
This key sentence seems nonsensical to me: “The discovery answers an age-old
questionthat has puzzled biologists since the time of Darwin: How can organisms be
so exquisitely complex, if evolution is completely random.” Evolution is anything but
random. Mutation is random, but evolution is directed by differential fitness, which is
definitely not random.- Benjy Weinberger
Yeah, that’s the basic mistake as I understand it. – j1m
I would assume the creationism vs. evolution debate is not either/or. For those who
have some religion, it can be safely assumed that evolution could be directed -
essentiallyas a tool of creation. – Louis Gray
I suspect that PZ Meyers (in the second piece referenced by Ruchira) is correct in
saying; “The other problem that often occurs is that one of the investigators opens his
mouth and reveals that he is completely out of his depth, and that the team has absolutely
no conception of how evolution actually works. This time, there is no exception.” – You
The researchers should perhaps go have a look at some of Chilean biologists
Humberto Maturana & Francisco Varela (circa 1973) on Autopoiesis [structures,
based on an externalflow of molecules and energy, produce the components which,
in turn, continue to maintainthe organized bounded structure that gives rise to these components]. Nor is it any surprise that a viable system exhibits homeostasis. – You

Breadcrumbs for November 13th through 23:00

   Posted by: dhcsoul    in Breadcrumbs

These are my links for November 13th from 22:43 to 23:00:

  • Personal VSM – If one wishes to change the world, one must first change oneself. This was one of Heinz von Foerster’s profound teachings and one that has great applicability today as it seems that many aspects of our lives threaten to spiral out of control. Here in Ontario, which is one of the more tranquil areas on earth, we have had continuing security fall-out from the World Trade Center attack, the Walkerton water system’s e-coli contamination, SARS, a computer leasing scandal in city government and the electricity black-out in August. All appeared to be catastrophes or anomalies but, upon examination, all have been found to be events that we could have, and should have, been better prepared to meet. All the subsequent examinations exposed failures to see the whole picture and to respond with requisite variety when the first sign of trouble appeared.

An explanation for the Palin Doctrine

“Anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that “my ignorance is just as good as your knowledge.” — Isaac Asimov

Lessons Forgot

   Posted by: dsoul    in cybernetics

40+ years ago the cyberneticist Stafford Beer forecast that computerization would be a disaster if this “new” prescription of Shirky’s was not followed [Clay Shirky (shirky.com) It's Not Information Overload. It's Filter Failure delivered at the Web 2.0 Expo last week].

In a later radio broadcast summarizing some of his concepts (CBC Radio 1973; later published as “Designing Freedom” Anansi) Beer summarized the need this way:
