A new model suggests that inhospitable hydrodgen-sulfide rich waters could have delayed the spread of complex life forms in ancient oceans. The research considers the composition of the oceans 550-700 million years ago and shows that oxygen-poor toxic conditions, which may have delayed the establishment of complex life, were controlled by the biological availability of nitrogen....
