Naked Mole-Rat Queens Release a Chemical to Stop Other Females From Reproducing
Researchers have discovered that naked mole-rat queens emit a specific chemical odor that induces infertility in other females within the colony. This mechanism allows the queen to maintain her status as the sole breeder, ensuring her dominance over the colony's social structure.
Why it matters
This finding provides new insights into the biological mechanisms of eusociality in mammals, a rare trait that mirrors the social structures of insects like bees and ants.
It’s tough being a female in a naked mole-rat colony; they live a long life of servitude, maintaining the tunnels of their underground world and caring for the queen’s offspring. Within the colony, a single ruling female is responsible for all breeding while the rest are rendered to a life of infertility. Scientists have long wondered how the naked mole-rat queen maintains this status quo, and now they may finally have an answer.
In a study published in Nature, a team of researchers suggests that naked mole-rat queens emit a chemical that prevents other females in their colony from reproducing. The compound’s odor induces infertility in the colony’s females, ensuring that the queen is the only one capable of producing offspring so that she may continue to rule over her kingdom uncontested.
