  3. Discovery of GFAJ-1, at Mono Lake, California. The bacterium allegedly substitutes arsenate for phosphate in its biomolecules.

  4. Amateur Biology • 2009 study by Wolfe-Simon et al. • The search for the hypothetical organism: Mono Lake

  5. Critical Backlash “The claim is almost certainly wrong.” --Alex Bradley, PhD “Borderline fraudulent” “Never rules out the obvious alternative explanation” --Norman Pace, microbiologist --Steven Benner, astrobiologist “There must be a hundred things in that paper that have people going, 'Hey, wait, that can't be right.” --Rosie Redfield, microbiologist and professor of zoology
