    You are repeating what I have already said. The data collected in your field
    is based on physical devices.

    Please give me the relevant references!

    One must separate the data from the human analysis. Humans can analyze many
    things but in science what they analyze is data obtained by physical
    devices. Again, I have said that humans are detectors not only of the
    physical but that which is beyond the physical.

    I have never said that evolutionary science cannot in principle be study by
    means of physical devices. If I thought so I would not add the word science
    to the word evolutionary. There is no other way to study evolutionary
    theory---no more or no less than in forensic science. Moorad
