Biological Exuberance: Animal Homosexuality and Natural Diversity

There are notable exceptions, of course. A number of scientists have presented relatively value-neutral descriptions of same-sex activity in various species without feeling a need to overlay their own commentary on the behavior, and several authors have recognized that homosexual activity is a “natural” or routine component of the behavioral repertoire in certain animals. Zoologist Anne Innis Dagg, for example, offered a groundbreaking survey of the phenomenon among mammals in 1984 that was light-years ahead of her contemporaries, while the more recent work of primatologist Paul L. Vasey is beginning to directly address some of the inadequacies and biases of previous studies.¹² Aside from these few examples, though, the history of the scientific study of animal homosexuality has been—and continues to be—a nearly unending stream of preconceived ideas, negative “interpretations” or rationalizations, inadequate representations and omissions, and even overt distaste or revulsion toward homosexuality—in short, homophobia.¹³ Moreover, not until the 1990s did zoologists begin to address such biased attitudes: Paul Vasey and Linda Wolfe are, so far, the only scientists to acknowledge in print that there may be a problem in their profession (and Wolfe the only one to name this specifically as homophobia). The full extent, history, and ramifications of the problem, however, have not been previously discussed or documented.

The Perversion of Scientific Discourse

From a distance this might be mistaken for fighting, but perverted sexuality is the real keynote … . In fact, the birds seem sometimes hardly to understand themselves, or to know where their feelings are leading them … . My principal observation during the earlier part of the time … was a repetition of what I have before noted in regard to the sexual perversion, as one calls it—a term which serves to save one the trouble of thinking … .

In many ways, the treatment of animal homosexuality in the scientific discourse has closely paralleled the discussion of human homosexuality in society at large. Homosexuality in both animals and people has been considered, at various times, to be a pathological condition; a social aberration; an “immoral,” “sinful,” or “criminal” perversion; an artificial product of confinement or the unavailability of the opposite sex; a reversal or “inversion” of heterosexual “roles”; a “phase” that younger animals go through on the path to heterosexuality; an imperfect imitation of heterosexuality; an exceptional but unimportant activity; a useless and puzzling curiosity; and a functional behavior that “stimulates” or “contributes to” heterosexuality. In many other respects, however, the outright hostility toward animal homosexuality has transcended all historical trends. One need only look at the litany of derogatory terms, which have remained essentially constant from the late 1800s to the present day, used to describe this behavior: words such as strange, bizarre, perverse, aberrant, deviant, abnormal, anomalous, and unnatural have all been used routinely in “objective” scientific descriptions of the phenomenon and continue to be used (one of the most recent examples is from 1997). In addition, heterosexual behavior is consistently defined in numerous scientific accounts as “normal” in contrast to homosexual activity.¹⁵
