Preti, Antonio (2018) Animal suicide: Evolutionary continuity or anthropomorphism?. Animal Sentience 20(10)
David M. Peña-Guzmán, Can nonhuman animals commit suicide?
Evolutionary processes are characterized by both continuity and discontinuity. Evidence on suicide in nonhuman animals is faint and often rests on the metaphorical or anthropomorphic use of the term. Suicidal behavior might be an evolutionary jump relatively recent in our species: a byproduct of living in groups of people who are not as closely related genetically as in social groups of nonhuman mammals.
