Post-Darwin Skepticism And Run-Of-The-Mill Suicide, John Hadley
Animal Sentience
Peña-Guzmán’s depiction of the opponent of animal suicide as a conservative is a straw man. It is possible to accept that animals are self-conscious and reflexive yet still reject the view that they have the mental wherewithal to commit run-of-the-mill suicide. That animal behaviour can be positioned on a continuum of self-destructive behaviour does not establish that animals can intentionally kill themselves.

Animal Sentience
Affective variation from euphoria to dysphoria, best understood in humans, is also found in the behavior and neurochemistry of many other mammals. Suicide in humans typically occurs in highly dysphoric and despondent individuals. Self-injurious behavior has been observed in dysphoric and despondent nonhuman primates. In humans, suicide is facilitated by a highly-evolved neocortex giving rise to behavioral flexibility and culture. As Peña-Guzmán indicates, some other mammals also have elaborate neocortices and the capacity for cognitive insight, particularly apes, delphinids, and whales. Suicide is most likely to occur in species where individuals live in stable groups of highly interdependent kin.
