Final answer:
The statement about polygyny in the question is false; polygyny refers to a marriage pattern where one man is married to more than one woman at a time, whereas polyandry is when one woman is married to more than one man.
Step-by-step explanation:
The statement given in the question is false. Polygyny is a marriage pattern where one man is married to more than one woman at the same time. The concept described incorrectly in the question defines polyandry, which is a marriage pattern in which a woman is married to more than one man at a time. Polyandry is comparatively rare and is known to occur in certain cultural and regional contexts. On the contrary, polygyny is more prevalent and can be associated with specific societal benefits, such as maximizing the family labor force and creating wide kinship networks, although it may also foster gender inequalities and familial conflicts.
