    Bertvan:
    Hi Tedd: I don't see where Hughes spelled out any science that was "really
    bad". The whole thing leaves me with the impression that Hughes would prefer
    to silence any scientist who considers the posibility of design in nature,
    rather than discuss the subject.

    Hughes:
    >...The most curious aspect of the meeting, and the most embarrassing for
    >Western scientists (particularly those form the United States), was the
    >presence of individuals supported by the Discovery Institute - a
    >Seattle-based foundation that proclaims intelligent design as a scientific
    >explanation for biological diversity.

    Bertvan:
    Are biologists embarrassed to find themselves at a scientific meeting
    attended by scientists with whom they disagree? Do they prefer not
    participate in any scientific discussion that includes people who consider
    the possibility of design? I don't regard such an attitude as scientific.
    I don't know to what extent design might explain evolution, but I will
    continue ardent support of ID until it is acknowledged as a legitimate
    possibility for consideration and discussion.

    Hughes:
    > The involvement of the Institute came
    >as a surprise to the more conventional attendees, especially when it became
    >obvious that the Institute had played a key role in the organization of the
    >conference, unbeknownst to the scientific community. Several talks were
    >presented along this theme, the main thesis of which seemed to be the old
    >Pallian arguments wrapped in a variety of molecular guises.

    Bertvan:
    The Pallian arguments are alive to many people who they feel such arguments
    are further supported by developments in molecular biology. Hughes
    obviously disagrees with the argument, but dismissing it as "old" does not
    dispose of it.

    Hughes

    >explanation for biological form, Paul Nelson on maternal effect genes, and
    >Jonathan Wells on homeotic genes. It takes guts to expose yourself in this

    >demands if science is your objective. I was depressed to find that my
    >rudimentary understanding of molecular biology was sufficient to spot
    >egregious errors, candidly dispatched by Eric Davidson.

    Bertvan:
    Accusing someone with whom you disagree of "egregious errors" without being
    specific hardly sounds scientific. Nor does it inspire confidence in the
    accuser. I suspect that if anyone had made an "egregious scientific error",
    Hughes would have gleefully reported it, rather than feeling depressed. You
    disagree?

    Hughes:
    > Well's claim that
    >aspects of *Hox* gene control, instead of providing yet more evidence for
    >homology and common ancestry, actually suggest that all metazoan phyla
    >arose independently gives the flavor of what was offered. In doing so he
    >effectively denied any defensible meaning in the words such as deuterosome
    >or ecdysozoan, well established higher taxa which have been erected on
    >characters other than those genes that influence segment identity. A bold
    >claim, but one he could not reasonably defend as questioning revealed.

    Bertvan:
    The Chinese have apparently found excellent fossils of some 40 or more animal
    phyla, including a chordate for which no earlier ancestral forms have been
    found. Earlier fossils of sponges were found. All of these organisms
    appeared at the approximately same time, and it seems unlikely they evolved
    from each other. I haven't seen convincing evidence that they evolved by
    "random mutation and natural selection". To my unscientific eyes their
    appearance in the fossil record seems a mystery. If Hughs has the solution
    to that mystery, I doubt he'll convince the public by merely tossing out
    words like "deuterosome" and "ecdysozoan".

    Hughes:
    >Denton was dismayed that biotic systems are more complicated than some
    >geneticists had expected in the 1960s, but the logical connection between
    >this and his belief in immutable natural designs was left unexplained. And
    >so it wen ton. The only thing new here was the presence of these arguments
    >at a meeting that was ostensibly billed as being scientific.

    Bertvan:
    I'm confident Denton was not "dismayed" at the complexity of biotic systems.
    Such complexity is part of his argument that nature is designed. Nor does
    Denton believe in "immutable natural designs". I've heard of no ID who
    does. Denton, Nelson and Wells are scientists, even though they entertain
    theories with which Hughs disagrees. Such misstatements of Denton's
    position destroys Hughes credibility as a scientist, as far as I am
    concerned.

    Hughs:
    >How does one deal with such situations? Those speaking were accompanied by
    >a coterie of supporters, including a "cosmic reporter" and one-by-one
    >scientists attending courteously answered their questions. Many of us,

    >clear is that the Discovery Institute is actively encouraging Chinese
    >scientists, by means of funding, to promote a view of the Chengjiang fauna
    >to which they are sympathetic.

    Bertvan:
    Hughes suspects the motives of the Chinese scientists? He suspects them of
    being pawns of "political forces" in the United States? Of having been
    "bought" by the Discovery Institute?

    >Hughes:
    >Several Chinese scientists gave presentations that emphasized the sudden
    >appearance of phyla, hinting at the need for a new "top-down" mechanism of
    >evolution - music, of course, to creationionist ears.

    Bertvan:
    It sounds like Hughes' objection to a "top-down" mechanism of evolution is
    not so much the validity of such a mechanism, but a rejection of anything
    which might "be music to creationist ears". It apparently does no good to
    point out that ID is not creationism, indeed many IDs are not even religious
    and have no interest in whether or not something is "music to creationist
    ears". I could respect Hughes' right to a difference of opinion; his
    continued misrepresentation of those who disagree with him must mean he
    hasn't bothered to familiarize himself with their arguments.

    Hughes:
    >Although the
    >Chenjian fauna does forcefully remind us that many body plans were firmly
    >established by early in the Cambrian, it does little more than focus
    >attention on the interesting things that happened around the
    >Precambrian/Cambrian boundary. The "phylogenetic lawn" idea is hardly new
    >(recall, for example, Gould's *Wonderful life*), and is clearly an

    >that haunts rationality in the United States, but it is also willing to
    >employ a little cultural imperialism if it furthers the cause.

    Bertvan:
    Wow! Creationism has captured the Chinese Communist party!! ;-) I don't
    think anyone claims Chinese scientists have new evidence that questions the
    very basis of evolution. Like some of us in the US, they might question
    Darwinism, "random mutation and natural selection" as an explanation for
    macro evolution. I find Hughes' suggestion that Chinese scholars are "being
    bought" by people promoting creationism in poor taste. I don't expect you to
    defend Hughes' words, Tedd, but you did ask where I disagreed . You claim
    Hughes is "quite an expert on Cambrian life forms", and that may well be.
    One can become an "quite an expert" on such a body of knowledge and still be
    small minded.
