One prominent hypothesis attributes this rapid diversification to changes in the geochemical composition of the oceans. Geological evidence suggests a significant increase in the concentration of dissolved oxygen in seawater during the late Precambrian era. Higher oxygen levels would have supported more metabolically demanding lifestyles. Unlike their anaerobic predecessors, organisms with access to abundant oxygen could develop larger body sizes and more complex tissue structures, such as collagen, which requires oxygen for synthesis. Thus, the lifting of an environmental "oxygen constraint" may have acted as a trigger, allowing genetic potential to be realized in the form of hard shells and segmented bodies.
