Polymorphism allows a function or operator to perform different tasks depending on the types of the arguments or operands. Polymorphism is the use of a single symbol to represent many different kinds, or the provision of a single interface to entities of different types, in programming language theory and type theory.
The idea is to operator derived from a biological theory that states that an organism or species can go through a variety of shapes or stages. The 1960s saw a substantial increase in interest in polymorphic type systems, and by the end of the decade, actual implementations were starting to surface.

Answer:
Ancient civilizations based a large part of their economy and their subsistence on trade and exchange of goods. Thus, they were guided by a very simple premise: they traded what they had left over, to obtain in exchange what they lacked. For example, if a civilization overproduced wheat, it could trade that surplus for goods it did not have, such as animals. In this way, all civilizations covered their needs without the obligation to procure them all by their own hand.
Answer:
In some cases (for example, that of the Talensi), an independent community or chiefdom was aware that others like it shared the same culture and social structure, and there were occasional common rituals that brought independent communities together. In other cases (for example, the Dagaba), political and cultural boundaries were not sharp, and there was no sense that an ethnic group included some communities and excluded others, although shifting distinctions were made based on various cultural traits. In the case of the Dagaba, the most important or recurrent of these distinctions seemed to be, and in the mid-twentieth century continued to be, whether inheritance was exclusively determined in the patrilineal line or, at least in part, followed the matrilineal line.
