More than just (feathered) friends: 'Lesbian' albatrosses on Oahu, where same-sex pairs have raised a third of the Hawaiian island's albatross chicks

Homosexuality exists through almost the entire animal kingdom and may even be vital for the survival of the species, according to new research.

Same-sex pairings have previously been observed in more than 1,000 species including dolphins and penguins, but now scientists say they also happen among worms, frogs, birds and many, many others.

The findings fly in the face of conventional views of how animal species thrive and are bound to ruffle the feathers of those who believe homosexuality is unnatural.


Evolutionary biologist Dr Nathan Bailey said: 'It's clear same-sex sexual behaviour extends far beyond the well-known examples that dominate both the scientific and popular literature - for example, bonobos, dolphins, penguins and fruit flies.'  

Almost a third of Laysan albatrosses on the Hawaiian island of Oahu have been raised by two females.

Other animal species tend to show homosexual pairings in lower proportions of about 10 per cent, the same fraction that has long been controversially claimed for humans.

有科学依据吗？

其实标题说的不完全对，动物中存在稳定同性恋关系的不多，我记得只有人，羊和企鹅。
其他的动物存在类似于同性恋关系。

虽然我认同同性恋，但在这个BBS出现太多有关同性恋话题似乎不太恰当！
