Complete the interpretation of these events as feedback regulation at the level of the biological community Match the terms in the left column to the appropriate blanks in the sentences on the right. Not all terms will be used. natural selection protective shells smaller lower microRNAs forms of locomotion genetic drift higher oxygen larger TRNA Hoz genes There are several current hypotheses. During the Cambrian period, predators acquired novel adaptations, such as that helped them catch prey, while prey species acquired new As new predator-prey relationships emerged, defenses, such as may have led to the decline of some groups and the rise of others. Another hypothesis focuses on an increase in atmospheric Cambrian explosion. It would have enabled animals with Reset Help that preceded the metabolic rates and body sizes to thrive, while potentially harming other species A third hypothesis proposes that genetic changes affecting development, such as the origin of and the addition of new facilitated the evolution of new body forms These hypotheses are not mutually exclusive, however, predator-prey relationships, atmospheric changes, and changes in the regulation of development may each have played a role
