Biological Exuberance: Animal Homosexuality and Natural Diversity

Although intended ostensibly to reveal important behavioral and developmental effects, the “treatments” applied to animals have in some cases been disturbingly similar to those administered to homosexual people in an attempt to “cure” them (separation or removal of partners, hormone therapy, castration, lobotomy, and electroshock, among others). Numerous primates, rodents, and hoofed mammals, for example, have been subjected to hormone injections to see how this might affect their homosexual behavior or intersexuality. Macaques were castrated as part of behavioral studies that included investigations of homosexual activity, as were White-tailed Deer to determine the “cause” of transgender in this species. Cats have even been lobotomized in order to study the effect on their (homo)sexuality. In some cases, biologists have gone so far as to kill individuals participating in same-sex activities (e.g., Common Garter Snakes, Hooded Warblers, Gentoo Penguins) in order to take samples of their internal reproductive organs.⁸ The reasons for this—usually to verify their sex or to determine the condition of their reproductive systems, including the presence of any “abnormalities”—reveal the incredulity as well as the often distorted preconceptions that many scientists harbor about homosexuality. As we will see in the next sections, these attitudes often carry over into the “interpretation” or “explanation” of homosexuality/transgender as well.

“A Lowering of Moral Standards Among Butterflies”: Homophobia in Zoology

… I have talked with several (anonymous at their request) primatologists who have told me that they have observed both male and female homosexual behavior during field studies. They seemed reluctant to publish their data, however, either because they feared homophobic reactions (“my colleagues might think that I am gay”) or because they lacked a framework for analysis (“I don’t know what it means”). If anthropologists and primatologists are to gain a complete understanding of primate sexuality, they must cease allowing the folk model (with its accompanying homophobia) to guide what they see and report.

—primatologist LINDA WOLFE, 1991⁹

There is an astounding amount and variety of scientific information on animal homosexuality—yet most of it is inaccessible even to biologists, much less to the general public. What has managed to appear in print is often hidden away in obscure journals and unpublished dissertations, or buried even further under outdated value judgments and cryptic terminology. Most of this information, however, simply remains unpublished, the result of a general climate of ignorance, disinterest, and even fear and hostility surrounding discussion of homosexuality that exists to this day—not only in primatology (as Linda Wolfe describes), but throughout the field of zoology. Equally disconcerting, popular works on animals routinely omit any mention of homosexuality, even when the authors are clearly aware that such information is available in the original scientific material. As a result, most people don’t realize the full extent to which homosexuality permeates the natural world.

Scientists are human beings with human flaws, living in a particular culture at a particular time. Although the profession demands standards of “objectivity” and nonjudgmental attitudes, a survey of the history of science shows that this has not always been the case. For example, the sexism of much biological thinking has been exposed by a number of feminist biologists over the past two decades.¹⁰ They have shown that not only are scientists fallible human beings, but most are men—and their scientific theorizing has often been (and in many cases continues to be) detrimentally colored by their own and their culture’s (often negative) attitudes toward women. This observation can be taken a step further: scientists (who are often heterosexual) frequently project, consciously or unconsciously, society’s negative attitudes toward homosexuality onto their subject matter. As a result, both scientific and popular understanding of the subject have suffered.¹¹
