there have been a number of studies in recent times proving species after species engaged in same sex activity...
Scientists now examining the truth of the Sea Horses fabled monogamy came in for a surprise!They've been keeping it from us: There are homosexual and bisexual animals, ranging from charismatic megafauna like mountain gorillas to cats, dogs and guinea pigs. There are transgendered animals, transvestite animals (who adopt the behavior of the other gender but don't have sex with their own), and animals who live in bisexual triads and quartets.
A study indicates that the sea creatures are promiscuous, flighty and more than a little bit gay — none more so than the Australian seahorse. And unlike human rules of attraction, it was the members of the Hippocampus genus with the biggest bellies that attracted the most partners.
The results also suggested that of 3,168 recorded sexual encounters, 37 per cent were same-sex liaisons.Source 1Paul Bullimore, a Sea Life Centre marine curator, said: “The results of the survey came as a revelation to all of us. The fabled monogamy of the seahorse really has been exposed as a myth. We were pretty sure there was far more promiscuity among seahorses than is generally acknowledged, but we hadn’t picked up on the same-sex liaisons.

how much more evidence do we need that what is termed homosexuality is and has been natural throughout the animal kingdom?
