    I posted this in the Bio section w/o reply:

    Since I am discussing the bombardier beetle, I'll state now that I am NOT a creationist, and I am aware of the flaws with the creationist argument concerning this organism.

    That said I am wondering what the name and maybe some properties of the catalyst, involved in the hydroquinone/quinone; hydrogen peroxide/water redox reaction, are.
    wondering if anyone has answers here or could point me in the right direction.

    This may help.

    Catalases and peroxidases break hydrogen peroxide down. This oxidizes hydroquinones into quinones.

    ...it was made very clear by Gish what would happen if we mixed up these two chemicals in the laboratory. There would be an explosion. At a public meeting with Gish at San Diego University in 1978, Dr. Frank Aubrey and William Thwaits mixed hydrogen peroxide and hydroquinone in front of Gish. There was no explosion, but the mixture did turn brown."

    I don't want to hand-type any more of that, but the upshot is: the bombadier beatle story comes from a mis-translation (deliberate or not) of a 1968 German scientific article, where Creationists, for whatever reason, translated the German instable (unstable) into "explosive".

    There's a multi-page, anti-Creationist explanation of this in "Telling Lies For God", Ian Plimer, 1994, Random House. Page 69, in fact.


    (And at this point I pause to reflect that the last time a made a reference to a book, I was attacked for being a Creationist myself. How stupid, no, how unScientific, people are).
