Final answer:
Reliance on kinship is less in states than in other political systems because in larger-scale societies, kinship plays a smaller and more limited role. Kinship relationships determine both rights and obligations, but in smaller societies, kinship is more significant in life choices. In states, legal systems and institutions determine social roles.
Step-by-step explanation:
Reliance on kinship is less in states than in other political systems because in larger-scale societies, kinship plays a smaller and more limited role. Kinship relationships determine both rights and obligations to other people, but in small-scale societies with low population density, kinship identity plays a significant role in most of the life choices an individual will have.
In larger societies with higher populations, kinship places the local and familiar in opposition to a wider, more amorphous society, where relationships have less and less significance. So, while kinship still provides guidelines on how to interact with certain other individuals in all societies, its role is diminished in states.
For example, in smaller societies, kinship may determine who can marry whom, who inherits property, and who has leadership roles. In states, these roles are often determined by legal systems and institutions that are separate from kinship ties.
