I am not so sure
Homosexual behaviour has been observed in 1,500 animal species.
Same-sex behavior is a nearly universal phenomenon in the animal kingdom, common across species, from worms to frogs to birds, according to a review of existing research, funded by the University of California, Riverside.
“It’s clear that same-sex sexual behavior extends far beyond the well-known examples that dominate both the scientific and popular literature: for example, bonobos, dolphins, penguins and fruit flies,” said Nathan Bailey, the first author of the review paper and a postdoctoral researcher in the Department of Biology at UC Riverside.
Zoologists are discovering that homosexual and bisexual activity is not unknown within the animal kingdom.
Roy and Silo, two male chinstrap penguins at New York's Central Park Zoo have been inseparable for six years now. They display classic pair-bonding behavior—entwining of necks, mutual preening, flipper flapping, and the rest. They also have sex, while ignoring potential female mates.
Wild birds exhibit similar behavior. There are male ostriches that only court their own gender, and pairs of male flamingos that mate, build nests, and even raise foster chicks.
Filmmakers recently went in search of homosexual wild animals as part of a National Geographic Ultimate Explorer documentary about the female's role in the mating game.
Lions are also homosexual. Male lions often band together with their brothers to lead the pride. To ensure loyalty, they strengthen the bonds by often having sex with each other.
Homosexuality is also quite common among dolphins and killer whales. The pairing of males and females is fleeting, while between males, a pair can stay together for years. Homosexual sex between different species is not unusual either. Meetings between different dolphin species can be quite violent, but the tension is often broken by a "sex orgy".
Homosexual behaviour has been observed in 1,500 animal species.
"We're talking about everything from mammals to crabs and worms. The actual number is of course much higher. Among some animals homosexual behaviour is rare, some having sex with the same gender only a part of their life, while other animals, such as the dwarf chimpanzee, homosexuality is practiced throughout their lives."
Animals that live a completely homosexual life can also be found. This occurs especially among birds that will pair with one partner for life, which is the case with geese and ducks. Four to five percent of the couples are homosexual. Single females will lay eggs in a homosexual pair's nest. It has been observced that the homosexual couple are often better at raising the young than heterosexual couples.
