What term describes a behavioral phenomenon where an individual animal reduces its own reproductive fitness to increase the fitness of another individual?
Answer:
altruism
Altruism in biology refers to behaviors that decrease the actor's immediate fitness while increasing the fitness of a recipient. This is often observed in social insects or kin-selected behaviors where individuals sacrifice their own reproductive potential to support the survival or reproduction of relatives, thereby ensuring the propagation of shared genes.
