The most reasonable explanation, Dr Goulson argues, is that each year a few bumblebeeswhich have learnt the trick of nectar robbery in the previous season come out ofhibernation and start robbing flowers again.
Goulson博士认为最合理的解释是:每一年,一些熊蜂在过去季节里掌握了抢劫花蜜本领,它们冬眠后再次出来抢劫。
By chance, they make more holes on one side of the flowers than the other, and as the habitis picked up by other, newly hatched bees, a preference for left or right spreads by aprocess of positive feedback.
它们偶然间在花的一侧制造出更多的抢劫孔。由于其他新孵化出的熊蜂效仿了这种习惯,左利手或右利手作为一种正反馈进行传播。
The bees have, in other words, created a simple culture.
或者说,熊蜂创造出一种简单的文化。
It is a criminal culture, admittedly.
诚然,这是一种罪恶的文化,
But no one ever said that nature was pretty.
但没有人曾说,自然界原本是优雅的。
