However, relevant studies have shown that early animals did not have a high demand for oxygen. There is also a view that ocean oxidation is the result of the Cambrian Explosion, not the cause. It can be seen that the feedback mechanism between the early Cambrian ocean oxidation and the "explosion of life" is still unclear and needs further exploration.
