In 1996, homosexual scientist Simon LeVay admitted that the evidence pointed to isolated acts, not to homosexuality:
"Although homosexual behavior is very common in the animal world, it seems to be very uncommon that individual animals have a long-lasting predisposition to engage in such behavior to the exclusion of heterosexual activities. Thus, a homosexual orientation, if one can speak of such thing in animals, seems to be a rarity."
Despite the "homosexual" appearances of some animal behavior, this behavior does not stem from a "homosexual" instinct that is part of animal nature. Dr. Antonio Pardo, Professor of Bioethics at the University of Navarre, Spain, explains:
"Properly speaking, homosexuality does not exist among animals.... For reasons of survival, the reproductive instinct among animals is always directed towards an individual of the opposite sex. Therefore, an animal can never be homosexual as such. Nevertheless, the interaction of other instincts (particularly dominance) can result in behavior that appears to be homosexual. Such behavior cannot be equated with an animal homosexuality. All it means is that animal sexual behavior encompasses aspects beyond that of reproduction"
