The Evolution of Eusociality in Naked Mole-Rats
Quick fact
Naked mole-rats are the only eusocial mammals—they live in colonies where only one female breeds, and most individuals spend their lives as non-reproductive workers, a system driven by extreme inbreeding and kin selection.
Why this is interesting
You've heard of eusocial insects like ants and bees, but what if a mammal—a rodent with a backbone—also lived in a colony with a single breeding queen and countless workers?
