In the same tone, a dainty motif of plume rose
Nearly 500 species of animals (ranging from mammals through to insects) have been observed performing homosexual behaviour, according to Aldo Poiani, a biologist at the University of Melbourne.
In addition to penguins, he says, koalas, flamingos, giraffes, monkeys, killer whales and dolphins are on list. In some cases, the animals commit themselves to a same-sex partner for life (like penguins), although in other species it appears that they have no preference, but rather act ‘bisexually’. […]
“Homosexual behaviour occurs in over 130 species of birds, yet explaining its maintenance in evolutionary terms appears problematic at face value, as such sexual behaviours do not seem in immediate pursuit of reproductive goals,” McFarlane and colleagues wrote in the journal Animal Behaviour in late 2010. […]
Darwin’s theory of evolution by natural selection suggests that animals, including humans, exist in order to continue their species, or rather, reproduce. It is an evolutionary paradox, says McFarlane, that animals engage in homosexual behaviour when “the prevailing view (is) that sex is for reproduction only”, which makes it scientifically significant to explain. According to Darwin’s theory, it’s a scientific conundrum that evolution hasn’t eliminated individuals that are not going to actively reproduce.
According to RV Kirkpatrick, an anthropologist from the University of California, Davis, in the Darwinian view, individuals should seek to maximise reproductive success. “Homosexual behaviour is too widespread to be a fluke or an aberration, but evolutionists in particular should be puzzled by its ubiquity,” he wrote in the journal Current Anthropology in 2000. […]
One theory is that because the percentage of exclusive homosexuality in both the animal and human world is so small, it poses no threat to the continuation of a species.
