Final answer:
Polyandry is practiced among the Nyinba of Nepal, where brothers share a single wife to effectively manage limited resources and land.
Step-by-step explanation:
Yes, polyandry is indeed a practice found among the Nyinba people of Nepal. This practice is a specific form of polygamy that involves one wife having more than one husband. In the context of the Nyinba, fraternal polyandry is practiced which allows brothers within a family to marry a single wife. This arrangement helps manage resources effectively, especially in areas with scarce land and resources. It promotes economic stability and minimizes population expansion by maintaining family land undivided, reducing household inequality and managing labor demands across multiple locations.
