arsenic based life form

As I wrote elsewhere, we biologists are limited in our forecasts by
having a single life sample. So we don't know what is universal and
what is parochial and our searches are unavoidably biased in terms of
their setup and possible interpretations. The results from this work
do not extend the life sample number. Nor do they tell us anything
about terrestrial evolution, because they showcase a context-driven
re-adaptation, not a de novo alternative biochemistry. However, they
hint that at least one of the CHNOPS brigade may be substitutable in
truly extreme (by our circumscribed definition) conditions.
