人类和其他高级灵长类动物为什么会仁慈、慷慨和自我牺牲?

这种看似无私的行为,使得解释人类和其他一些高级灵长类动物的利他主义成为一个特殊难题。
毕竟,在进化论上,仁慈、慷慨和自我牺牲是毫无意义的。当一个人的生存和基因的传播可能取决于他为自己囤积每一个优势,为什么他会放弃任何东西来造福他的同类成员呢?

A new study further burnishes the marmoset’s reputation for admirable community values. Researchers report that these caregivers share their food more generously with little ones in private than when they’re ­surrounded by the watchful eyes of other community members.

“The marmoset pattern of results calls to mind the so-called diffusion of responsibility effect, which is well established in ­humans,” the authors wrote. “People are less likely to help in the presence of a larger number of bystanders, but feel more responsible when alone with a needy individual.”
