Eusociality and Kin Selection
Captions available
The idea
Eusociality is cooperative brood care, overlapping generations, and division of labor; kin selection explains sterile workers via inclusive fitness.
In practice
A sterile worker bee raises her queen's brood, sharing many of her genes, raising inclusive fitness despite zero direct reproduction.
Where people slip
Selection does not act for the species' good — sterility persists because it raises the worker's own gene copies, not colony welfare.
