    Electronic Telegraph 28.09-00 What really killed T. Rex? A deep impact
    and colossal explosion on Earth 65 million years ago is blamed for wiping
    out the dinosaurs... but the asteroid may be innocent. ... The ultimate
    disaster movie scenario is based on a serious scientific hypothesis proposed
    in 1980 by the American team Professors Walter and Luis Alvarez, who
    carried out what was undoubtedly one of the most remarkable pieces of
    detective work known to science. They started with the investigation of a
    thin layer of dirty sulphurous clay in Gubbio, Italy. This clay marked what
    scientists call the K-T boundary, which marks the junction between rocks
    in which the fossils of dinosaurs and their peers are found, and those above,
    in which dinosaur bones are never found but have been replaced by a new,
    more modern fauna. ... the Alvarezes were able to track back and find
    evidence for a giant impact on the Earth exactly 65 million years ago. In
    1991 the Chixculub impact structure was discovered, centred on the
    Yucatan peninsula in Mexico, and dated at exactly 65 million years and so
    they were proved to have been spot on. .. But the next step in the story - a
    hypothesis blaming the impact for the K-T extinction - is not nearly so neat.
    Many Earth scientists were coming up with a different scenario for the
    disappearance of 75 per cent of life on Earth. ... The Deccan Traps in India,
    stretching from Bombay almost to the Himalayas, form 200,000 square
    miles of layer upon layer of such black basalt lava flows. ... These flood
    basalts were extruded from long fissures in the Earth at exactly the same
    time as the dinosaurs died. ... In the late 1980s a number of scientists
    started to turn to the Deccan as a possible cause of environmental
    degradation leading to the K-T extinction. The most prominent of these
    scientists was ... Prof Vincent Courtillot, who has now risen to become the
    chief scientific adviser to the French government. .... ... The beauty of
    Courtillot's idea is that it provides a possible cause for the whole K-T
    extinction, and not just the dinosaurs. For the extinction struck the sea as
    well - the elegant coiled ammonites and the great sea reptiles, the
    plesiosaurs, ichthyosaurs and pliosaurs were among the marine fauna wiped
    out. ... Despite this compelling evidence, the world and the media still
    favoured and accepted as fact - the Alvarez theory of asteroid impact. This
    is probably due, in part, to the fashion for disaster movies at the time, and
    to the strong personalities and charisma of the Alvarez team. ... "I feel
    very aware that the K-T impact bandwaggon has crushed a lot of valuable
    scientific evidence under its wheels," says Bob Spicer. "The facts of one
    part of science have become distorted and used by another branch to justify
    public spending." ... [Phil Johnson mentions on one of his tapes that Luis
    Alvarez (who he knew personally) bragged that he had by marginalised his
    main competitor, Prof. Dewey McLean (see link from this page) in order
    to get his asteroid impact theory established. If it turns out that McLean
    was right all along, this would be another example of how political power
    and the spirit of the age are more important in science than it's more
    uncritical devotees believe. Now what other important theory does that
    remind me of? :-)]

    http://www.independent.co.uk/news/World/Middle_East/2000-09/sculpture240900.shtml
    The Independent ... 'Lump of rock' turns out to be world's first sculpture ...
    24 September 2000 A stone dismissed by experts as no more than a lump
    of rock has been identified as the world's first sculpture and the oldest piece
    of figurative art ever seen. New scientific data suggests that early humans
    were producing representations of life 220,000 years ago ... It is a
    discovery which could revolutionise our understanding of human
    development. Italian and American archaeologists used powerful
    microscopes to prove that a figurine-like piece of volcanic stone from the
    Golan Heights ... is in fact a primitive sculpture, deliberately chiselled and
    shaped by human hands. ... The sculpture, which has been widely ignored
    since its discovery in 1986, is now likely to be acknowledged by most
    scholars as the world's oldest work of figurative art. Significantly, this
    recognition comes at a time when indirect evidence of other equally ancient
    artistic activity is coming to light in Zambia, Kenya and Europe. .... Such
    discoveries may have a profound impact on our understanding of the
    evolution of human thought. Archaeologists have always considered
    symbolic thought, as represented by art, to be the exclusive preserve of
    homo sapiens, our species. Although symbolic thought only really
    blossomed 100,000 years after the final emergence of homo sapiens some
    150,000 years ago, the new research suggests it may have existed in a
    simple form much, much earlier - between 200,000 and 350,000 years ago.
    Depending on what further discoveries are unearthed, archaeologists may
    have to start rewriting the origins of human thought, with homo sapiens in
    the role of developer rather than originator. ... [If this is the Berekhat Ram
    "Golan Venus" it is old news. It is only 1 inch long and looks *vaguely*
    like a woman's figure, with cut marks near the `neck'. Whether the cut
    marks were to accentuate the `neck' or just a failed attempt at making
    something else, or even naturally occurring scratches, is the question. From
    an ID perspective this is another example of archaeologists using a form of
    design inference to tell an artefact from a geofact-what Ratzsch calls
    "counterflow". If it is confirmed, I personally would not have a problem
    with incipient symbolic thought developing in a line leading to Homo
    sapiens (maybe even being anatomically modern H. sapiens?) 200-350 kya,
    since it would fit within my modified Pearce's two-`Adam' model.]

    landlady is to follow in Charles Darwin's footsteps after unearthing a rare
    first edition of his iconoclastic book the Origin of Species. Kathy
    Bickerstaff, 51, bought the book, published in 1859, for 50p at a church
    fete ...12 years ago. She only realised what the book could be worth when
    one of her guests noticed it was a first edition. It eventually fetched
    o11,600 at auction. ... Ms Bickerstaff...will fulfil a childhood dream when
    she travels to the Galapagos Islands, off Ecuador, where Darwin conducted
    his research for the book ... Darwin, travelling on board the ship HMS
    Beagle, discovered a volcanic archipelago that had remained much as it
    was millions of years ago. ... Darwin's theory - that the various types of
    plants and animals, including man, have their origin in other preexisting
    types - contrasted sharply with the teaching of the Church ... which claimed
    God had created the first humans, Adam and Eve, in his own image. There
    was strong resistance to Darwinian thinking but nowadays the theory of
    evolution is at the centre of mainstream science. ... [It is interesting how
    the story has become more mythological over time, i.e. 1) Darwin
    "discovered" the Galapagos -it was actually discovered in 1585!; 2) He
    "conducted his research for the book" - Darwin claimed to be a creationist
    at this stage and that he only thought of transmutation of species late in the
    voyage; 3) the implied claim that Darwin's theory contradicted the Bible's
    teaching that "God had created ... humans ... in his own image" (so much
    for Gould's NOMA!); and 4) that "the theory of evolution is at the centre
    of mainstream *science*!]

    US geneticist who died earlier this year has been accused of deliberately
    infecting thousands of Yanomami Indians with measles, killing hundreds of
    them. The geneticist, James Neel, worked in the Yanomami homeland in
    Brazil and Venezuela in the mid-1960s. A book to be published ... says
    Neel vaccinated the Yanomami as an experiment to test the effects of
    natural selection on primitive societies. The AAA is extremely concerned
    about these allegations ... it says his work was funded by the US Atomic
    Energy Commission, which wanted to research the consequences for
    communities of the mass deaths caused by a nuclear war. The book,
    Darkness in El Dorado, has been written by Patrick Tierney, a journalist. ...
    Professor Terry Turner ... who has read the proofs, has told the American
    Anthropological Association that the book reveals a "nightmarish story - a
    real anthropological heart of darkness". .. Neel also studied effects of
    Hiroshima and Nagasaki bombs on survivors ...[that] Neel's group had
    been involved in experiments in the US which included injecting people
    with plutonium without their knowledge. [and] Tierney's book will put the
    entire discipline of anthropology on trial. Although Neel himself is dead,
    many of his associates from the experiment are still alive. ... See also:

    be fair these allegations have not yet been proved. But if they are true the

    Darwinists following recent furores about claims by some social Darwinists
    that infanticide and rape is OK.]

    Electronic Telegraph ... 28 September 2000 'Ignorance' of Greens berated
    by scientist ... James Lovelock, 81, who is best known for his Gaia theory
    and the many environmental prizes he has won, said: "Too many Greens
    are not just ignorant of science, they hate science." Named after the Greek
    goddess of Earth by the novelist William Golding, Gaia theory says that
    creatures, rocks, air and water interact in subtle ways to ensure the
    environment remains stable. Gaia has exerted great influence on the Green
    movement, but in Homage to Gaia: The Life of an Independent Scientist,
    published today, Lovelock says that he has "never been wholly on the side
    of environmentalism". He likens Greens to "some global over-anxious
    mother figure who is so concerned about small risks that she ignores the
    real dangers". He wished they "would grow up" and focus on the real
    problem: "How can we feed, house and clothe the abundant human race
    without destroying the habitats of other creatures?" Unlike most Greens,
    Lovelock backs nuclear energy. "Some time in the next century, when the
    adverse effects of climate change begin to bite, people will look back in
    anger at those who now so foolishly continue to pollute by burning fossil
    fuel instead of accepting the beneficence of nuclear power. "Is our distrust
    of nuclear power and genetically modified food soundly based?" he asks, ...
    his disenchantment ... is similar to that of Patrick Moore... a founder of
    Greenpeace ... has an Orwellian view of the environmental lobbies as they
    are today." ... [Personally I think that much (not all) of the Green
    Movement is just nature worship, i.e. paganism, perhaps without even
    realising it? Still Lovelock is partly to blame for choosing the name Gaia.]

    ... 27 September, 2000 ... The smell of success ... Scientists believe our
    sense of smell played a crucial role in evolution, helping our Stone Age
    ancestors to hunt, avoid poisonous food and even select a mate. By
    comparing tiny variations in the DNA sequences of chimps and humans,
    researchers in Israeli have concluded that changes in about 1,000 smell
    receptor genes contributed to the rise of the human race. ... The authors
    believe smell receptors are one of the few examples of adaptive molecular
    evolution in humans - mutations in DNA that gave our ancestors an
    advantage over other early humans. ... The researchers found that the
    olfactory genes we use today had evolved through the mechanism of
    positive or advantageous selection. "Imagine everyone has the same gene
    and thus the same ability and then one human is born with a mutation in
    that gene and it changes its ability for the better," said Yoav Gilad ... "It's
    got a better sense of smell now. It can smell something that only he can
    smell, others cannot. "Let's say this smell is a smell of a poisonous plant.
    He knows by a smell that it is bad for him, while others might try it. It gives
    him an advantage. We call that a greater fitness. "Sooner than later,
    everybody will have this mutation, this new variant of gene, because this is
    an advantageous mutation." ... The work raises an intriguing question: why
    maintain a sharp sense of smell when it is no longer needed? One theory is
    that smell, even today, plays a role in sexual attraction. ... [Another `just-
    so' story for a laugh! It never seems to occur to Darwinists that they can
    pick out just about *anything* as "advantageous" and claim it was naturally
    selected, simply because it survived (how do we know it was
    advantageous? Because it survived. Why did it survive? Because it was
    advantageous). In this case there is even a `just-so' story to explain why it
    the "advantageous" trait declined but not completely-see tagline.]

    ... 27 September, 2000 ... When slime is not so thick ... Scientists have
    discovered that a single-celled organism can negotiate the shortest way
    through a maze. It means that some of the lowliest creatures in the plant
    and animal kingdoms, such as slime and amoeba, may not be as primitive as
    once thought. Pieces of slime mould, an amoeba-like organism, were
    enticed through a 30-square-centimetre (five-square-inch) maze by the
    prospect of food at the end of the puzzle. The researchers believe the slime
    is exhibiting some form of primitive intelligence. Toshiyuki Nakagaki ...
    placed pieces of the slime mould Physarum polycephalum in an agar gel
    maze comprising four possible routes. Normally, the slime spreads out its
    network of tube-like 'legs', called pseudopodia, to fill all the available
    space. But when two pieces of food were placed at separate exit points in
    the labyrinth, the organism squeezed its entire body between the two
    nutrients. It adopted the shortest possible route, effectively solving the
    puzzle.... "This remarkable process of cellular computation implies that
    cellular materials can show a primitive intelligence," ... [This might support
    Roger Penrose's claim that there is a form of quantum computing built into
    the cellular cytoskeleton so even the simplest living thing would exceed the
    fastest computer in processing power by orders of magnitude.]

    Electronic Telegraph 28.09-00 How to spot an Olympic cheat with a
    calculator... Extremes make a mockery of averages, and raise an interesting
    challenge of their own: for how can one tell if a record-breaking result is
    just "averagely" impressive, or so exceptional as to be suspicious? It is a
    question that is likely to be raised several times over the coming week in
    the athletics events at the Olympics. Everyone hopes for record breaking
    performances, but as past Olympics have shown, there is such a thing as
    being too exceptional: disgraced Ben Johnson's astonishing 9.79 seconds in
    the 100 metres at the 1988 Seoul Olympics being a notorious example. ...
    During the Twenties statisticians made the startling discovery that extreme
    events follow a mathematical law. Known as the Extreme Value (EV)
    distribution, its derivation stems from some sophisticated probabilistic
    arguments, but it still fits the common-sense view that the more extreme
    the event, the less likely it is to occur. Just how less likely can be worked
    out by analysing the past history of events. The idea of being able to
    predict extraordinary events strikes even some statisticians as somewhat
    fanciful, but EV theory is already being used by insurance companies to set
    premiums against such things as floods. Indeed, the whole of the
    Netherlands is protected by EV theory, whose equations were used to
    predict the optimal height for its sea dykes. One of its most impressive
    successes has only just become clear, however. In 1996, Prof Richard
    Smith, a British expert on EV theory, produced disturbing evidence that
    the world records set by the ... women trained by the Chinese coach Ma
    Junren were drug-assisted. ... Analysing the trend in the times for the 3,000
    metres, using EV theory, Prof Smith found that the probability of anyone
    breaking the record by so huge a margin was so small that "something very
    unusual" was taking place. Precisely what became clearer earlier this
    month, when Ma Junren's latest batch of runners were thrown out of the
    Sydney Olympics. They had tested positive for the banned substance
    erythropoietin (EPO), for which a test has only just become available. The
    suspicion must now be that the equations of EV theory had already
    detected the whiff of banned substance hanging over those astonishing
    figures in the record books. ... [An example of using low-probability theory
    (a la Dembski's explanatory filter) to detect intelligent design (i.e. drug
    cheating) as opposed to chance (athlete had a `peak' day) and law (what

    to try to save the life of a 6-year-old girl. The girl, Molly Nash, needed a
    bone marrow stem cell transplant that could cure her of a life-threatening
    blood disease. To find the proper stem cells, doctors at the Reproductive
    Genetics Institute first formed several embryos with eggs and sperm from

    the embryos for disease and picked one with a tissue type that matched the
    couple's ailing daughter and would provide her with an immune system to
    fight her disease. That embryo was implanted and a boy, Adam, was born
    to the mother. Taking stem cells from Adam's umbilical cord, the girl
    received the transplant last week, said Charles Strom, director of medical

    implantation had been used for this purpose. "It has been used to just get a

    "However, there is a real danger that in explaining so much the theory
    actually *explains* nothing. This is the core of the philosophical doubt
    facing Darwinism. An example of the perils of 'explaining too much' can be
    seen in the notion of adaptation. When a biologist finds a creature with an
    intricate and useful adaptation-such as the chameleon's ability to change
    colour to match its background-he immediately explains it in terms of
    natural selection and evolution. In fact the existence of such adaptations is
    frequently taken as proof of the power of selection. But what will the
    biologist say when he finds a similar lizard *without* this camouflage
    adaptation? The chances are he will conclude that such an adaptation is
    unnecessary for the survival of the second lizard, or that selection has not
    been strong enough to 'create' it. Both of these conclusions may be valid-
    they seem reasonable enough-but we are tempted now to ask him what sort
    of evidence would *contradict* the idea of selection? If the presence of
    adaptations is evidence for selection, but the absence of adaptations is not
    evidence against selection, then is it possible to deny the existence of
    selection at all? In other words if selection can explain everything then it
    really explains nothing. Good scientific theories should be testable and even
    falsifiable." (Leith B., "The Descent of Darwin: A Handbook of Doubts
