伟大的英国生物学家达尔文。为了证实一种生物跟别种生物有着互相联系的关系,仿佛组成了一种生命的网,他发现三叶草必须依靠蜂类传授花粉。因此,他首先用土蜂(即蜜蜂)给白三叶草和红三叶草进行传授花粉的实验,他把一部分花遮盖起来,不让蜜蜂来接触。结果是:没有遮盖的二十朵白 Great British biologist Darwin. To confirm that a living creature has a reciprocal relationship with other creatures, as if forming a web of life, he found that clover must rely on bees to impart pollen. Therefore, he first experimented with pollinating white clover and red clover with bumble bees (ie, bees) and covered some of the flowers to prevent the bees from touching them. The result is: 20 white without cover
