The Viking Biology Leader Harold (Chuck) Klein has written a paper
debunking Levin's rubbish. See: 'Did Viking Discover Life on Mars',
Origins of Life and Evolution of the Biosphere, 29: 625-631, 1999:

"[the assertion that] results of the Labelled Release experiment are analogous
to those observed with terrestrial organisms...is found to be implausible."

The complete paper was on-line but not anymore. If Robert and/or Justin are willing, I could send them the Pdf of the complete paper and they could host it on HZ's website. Maybe that would give BD a hint to peddle his garbage elsewhere,
(Wasn't BD banned from HZ for misrepresenting himself?).

Also Norman Horowitz (another Viking Biology team member) wrote a
book "To Utopia and Back" debunking the life-on-Mars thing. Rumor has it that Horowitz and Levin almost got into a fist fight at a scientific conference. Klein and Horowitz are honest scientists and unlike Levin have not tried to use the infotainment media to advance their scientific theories.
