What is a common trait found in every culture of mankind?

The funeral rite is a common trait found in every culture of mankind because it serves as a way for individuals and communities to acknowledge and cope with death, which is a universal experience. Across all cultures, people have developed various rituals and traditions related to funerals, reflecting their beliefs, values, and social structures. These rites perform essential functions, such as providing a sense of closure, allowing the expression of grief, and reinforcing social bonds among community members through collective mourning and remembrance.

In contrast to the universal nature of funeral rites, a caste system is specific to certain societies and is not found universally. The work ethic, while valued in many cultures, can greatly differ in interpretation and importance between different societies. Fraternal organizations, while present in various forms, are not a universal phenomenon and are often subject to cultural and social variability. Thus, the funeral rite stands out as a nearly universal aspect of human culture.
