動物中也有同性戀?(圖)

Wildlife studies have put focus to animal homosexuality for quite a long time. A recent research appears to have confirmed that homosexual behaviour in the animal world actually does exist. The conclusion again has caused great controversy in biology。

野生動植物學界對動物同性戀探討已久，目前一項最新研究似乎證實了同性戀現象的確在動物界存在，該結論卻再次引發學界爭議。

According to Telegraph, May 18, a study centered on an albatross colony at the University of Hawaii revealed that one third of albatross 'couples', are consistent of two females. Previously, some biologists had claimed that 'gay' animal behaviour has been spotted in 1,500 different species. For example, about a fifth of captive king penguins are gay。

據英國《每日電訊報》18日報道，出自夏威夷大學的最新研究表明，通過對鳥類信天翁的跟蹤調查，研究人員發現大約有1／3的信天翁家庭由兩隻雌信天翁組成。此前有科學家認爲，全球約有1500種不同種羣的動物存在同性戀行爲。比如，大約有1／5的帝企鵝是同性戀。

Sexuality is not just about making babies, it is also about making the flock work. For some animals, homosexuality is normal flock behaviour. For example, it is common for male black swans to raise cygnets as a couple。

性行爲並不只是指繁衍下一代，它也包括集體勞動。對於一些動物來說，同性戀行爲也包括平常的羣體勞作，比如，兩隻雄性黑天鵝一起撫養小天鵝也是非常平常的事情。

Professor Paul Harvey, at the University of Oxford, said it is unreasonable and inmature to compare our human concept of homosexuality and its societal effects with irrational animals'。

該結論引發爭議。牛津大學教授保羅認爲，人類把自己對同性戀的認識和非理性的動物行爲做比較是不可取的。
