DOI: 10.1073/pnas.2001063117
Abstract: Significance The oxygenation of the atmosphere about 2.4 billion years ago remodeled global cycles of toxic, redox-sensitive metal(loids), including that of arsenic, which must have represented a cataclysm in the history of life. Our understanding… read more here.
