The world's first museum exhibition about homosexuality among animals organized in Norway says bird and bees could be gay. The Oslo Natural History Museum now believes human homosexuality could be natural.

Geir Soeli, the project leader of the exhibition, told Reuters, "Homosexuality has been observed for more than 1,500 animal species, and is well documented for 500 of them."

A statement issued by the exhibition said, "We may have opinions on a lot of things, but one thing is clear -- homosexuality is found throughout the animal kingdom, it is not against nature."

The show that opened Thursday disputed religious condemnation for homosexuality. The project leader said a Dutch zoo had once organized tours to view homosexual couples among the animals. The exhibition supports the view that human homosexuality could be "natural."
