Abstract

When it comes to humans, ‘homosexuality’ refers to a variety of characteristics, ranging from sexual behaviours, desires, preferences, and orientations, to sexual identities. The question driving this paper is whether, and to what extent, it is justified to also ascribe such characteristics to nonhuman animals. Scientific opinions are divided on this issue, ranging from militantly positive to cautiously positive to markedly negative, with many in between suggesting we should at least change the vocabulary.
