Today, oxygen, or o 2, makes up about 21% of earth’s atmosphere, but for most of our planet’s long history, o 2 levels in the atmosphere and dissolved in the ocean were much less than they are today. The behaviour of oxygen and nitrogen as components of air led to the advancement of the phlogiston theory of combustion, which influenced chemists for a century or so, and which delayed an understanding of the nature of air for many years. The concentration of oxygen in the atmosphere is often cited as a possible contributor to large-scale evolutionary phenomena, such as the origin of the multicellular ediacara biota, the cambrian explosion, trends in animal body size, and other extinction and diversification events the large size of insects and amphibians in the carboniferous period, when the oxygen concentration in the.
