21-25 A naked mole rat colony, like a beehive, wasp’s nest, or termite mound, is ruled by its queen, or reproducing female. Other adult female mole rats neither ovulate nor breed. The queen is the largest member of the colony, and she maintains her breeding status through a mixture of behavioral and, presumably, chemical control. Queens have been long-lived in captivity, and when they die or are removed from a colony one sees violent fighting for breeding status among the larger remaining females, leading to a takeover by a new queen. Eusocial insect societies have rigid caste systems, each insect’s role being defined by its behavior, body shape, and physiology. In naked mole rat societies, on the other hand, differences in behavior are related primarily to reproductive status (reproduction being limited to the quee A. Naked mole rat colonies exhibit social organization based on a rigid caste system. B. Behavior in naked mole rat colonies may well be a close vertebrate analogue to behavior in eusocial insect societies. C. The mating habits of naked mole rats differ from those of any other vertebrate species. D. Naked mole rat colonies are the only known examples of cooperatively breeding vertebrate societies. 我来回答: 提交
