Final answer:
Sacrifice in ancient societies, particularly within the Aztec civilization, represented a complex mix of death and life, with socially structured ceremonies aimed at preserving the state and its classes. So the statement is true. Option a is correct.
Step-by-step explanation:
Sacrifice played a crucial role in ancient societies, particularly within the Aztec civilization. The act of sacrifice can be seen as a dual representation of death and life, where the taking of life was believed to ensure the continuance of life for the society as a whole.
The ritualistic practice had both literal and metaphorical implications. It was used to uphold the social order and moderate the class inequalities, with the underlying belief that such sacrifices were vital for the stability and prosperity of the state.
Furthermore, in the context of biological kinship, kin selection refers to the evolutionary strategy that favors the reproductive success of an organism's relatives, even at a cost to the organism's own survival and reproduction.
Thus, from a sociopolitical standpoint, sacrifices ensured the flow of labor and resources necessary to maintain a class of elites and the functioning of the Aztec state. The concept of sacrifice symbolized the bodily sacrifices commoners made through hard labor. In a biological context, sacrificing one's life for the continuation of the gene pool of relatives fits the definition of kin selection.
Hence, option a is correct.
