A cultural universal is a characteristic or pattern that is common to all human cultures. It is a social phenomenon that is found in every society, regardless of its location, time period, or level of development. Cultural universals can include things like language, art, music, religion, and family structures.
Cultural universals are important because they provide insights into the nature of human beings. They show that, despite our differences, we all share certain fundamental characteristics. This can help us to understand ourselves and our place in the world.
