Reciprocal food sharing is a form of reciprocal altruism where one individual gives up the food it has forged to another individual. Food sharing has been observed in a wide range of animals, including insects, birds, cetaceans, vampire bats, and primates. It is not always an active behavior; tolerance of theft may also be considered a form of food sharing (Stevens and Gilby). Not only does food sharing occur among members of the same family, but also among non-kin individuals as well, creating an interesting evolutionary question.

Famous quotes containing the words reciprocal, food and/or sharing:
“Parenting is a profoundly reciprocal process: we, the shapers of our children’s lives, are also being shaped.

—Augustus Y. Napier (20th century)
“Prose and poetry are as different as food and drink.”
—Franz Grillparzer (1791–1872)
“... probably all of the women in this book are working to make part of the same quilt to keep us from freezing to death in a world that grows harsher and bleaker—where male is the norm and the ideal human being is hard, violent and cold: a macho rock. Every woman who makes of her living something strong and good is sharing bread with us.”
—Marge Piercy (b. 1936)
