    "Their record indicates a dramatic increase in the oxygenation of the #oceans during the Late #Paleozoic era, hundreds of millions of years after the emergence of the first #animals. This aligns with other evidence... supports the hypothesis that animals have evolved in oceans that were mostly oxygen-limited"
