Final answer:
Certain social customs in early civilizations, such as strict class systems and gender roles, hindered social mobility and promoted inequality, which could be detrimental to societal growth.
Step-by-step explanation:
Throughout history, certain social customs have been detrimental to societal growth. For example, when early civilizations formed, they were marked by a reliance on agricultural surplus which increased family size and the population. However, this led to an increase in hierarchical social systems which could stifle social mobility and promote inequality.
Additionally, customs such as those that discouraged the integration of different societal groups or castes limited the full potential of societies. For instance, in early civilizations, roles and responsibilities were often strictly defined, with men generally taking on more lucrative work like cocoa farming, creating gender inequalities. On the other hand, customs that promoted unity and collective correction of behavior, such as the San's ritual dance, had a positive impact on societal cohesion and problem-solving.
