Final answer:
Dividing people along lines of social status, such as castes, illustrates social stratification. The Indian caste system categorizes individuals based on birth and ties to karma and reincarnation beliefs. Although reforms have occurred, caste influences still persist in societal roles and interactions.
Step-by-step explanation:
Dividing people along lines of social status, such as caste does, is an illustration of social stratification. The caste system, notably the one in India, assigns individuals to societal roles based on the social class into which they are born, which has historically included the Brahmins, Kshatriyas, Vaishyas, Shudras, and the untouchables or Dalits. This system reflects the belief in karma and reincarnation, where a person's current status is thought to be the result of their actions in past lives. Despite legal reforms in modern India, aspects of the caste system remain socially relevant and often influence individuals' occupations and social interactions. The concept of caste as a social organizer is still defended by some, claiming it provides a form of social and political unity for those within the same group.
