    As has been noted many times, random in this context does not mean
    "without meaning purpose, plan, or design". Any "meaning purpose, plan, or
    design" is not detectable with scientific instruments. For example, in
    information
    theory one measures the quantity of information in a message irrespective of
    what it means. One would not conclude from this that messages have no meaning.
    Also, consider the engineer that designs complicated mechanisms by mimicking
    Darwinism, i.e. by random variations coupled with a selection criteria.
    Would the
    random variations be "without meaning purpose, plan, or design" in this case?
