It’s difficult to see how spite could evolve: what benefit is there in punishing another party at the cost of harming one’s own reproductive fitness? “Six years ago, no one thought it was possible,” says Oxford University evolutionary biologist Stuart West. Some researchers have suggested that natural selection can favor spite if the recipient is less related to the actor than would be expected by chance. But this circumstance would not be widespread in nature, limited to small populations or to social insect colonies where sterile workers and soldiers have nothing to lose in terms of individual reproductive fitness. Hadas Hawlena, a postdoc in evolutionary biologist Curt Lively’s Indiana University lab, became interested in a different hypothesis for the evolution of spiteful behavior. The hypothesis

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.
