Sheila Conant: We used to have birds that pollinated specific species of plants, and some of those plants have become very rare because their pollinators have become extinct.
希拉•柯南特:曾经会有某些鸟类给一些植物授粉,但是当这种鸟类灭绝后这些植物也变得越来越稀少。
Nonetheless, the earliest flowers appear to have been pollinated by insects, and the full-scale blossoming of flowering plants coincides with the rise of animals as go-betweens.
尽管如此,早期的花朵似乎也靠昆虫来传递花粉,随着充当花媒的昆虫的增加,开花植物全面开花的日子也就到来。
