Previous studies in altruistic behavior were mainly performed on humans with noninvasive techniques, and very few was done on rodents due to their relatively simple social behaviour and uncommon altruistic behaviour. Altruistic behavior is common throughout the animal kingdom, particularly in species with complex social structures. Group selection interpretation To explore the underlying neural mechanism, the researchers performed functional magnetic resonance imaging on conscious marmosets. Such infant-induced modification of neural activity offers a window for examining the neural basis of altruistic behaviors in marmoset monkeys. IV. What observation might best explain this behavior? A Counter-example of Apparently Altruistic Behavior: Alarm Calls If the predator moves slowly, alarm calls don't cost much- just a few calories. 1 Nice monkeys?
