So, instead of looking up to learn  about the evolution of trees, it turns out paleobotanists should've  been looking down all along.

因此，古植物学家与其抬头了解树木的进化，不如一直往下看。

But to paleobotanists, Archaefructus is incredibly exciting, because it's among the earliest known examples of an angiosperm – what biologists call flowering plants.

但对于古植物学家来说， 古生果属令人难以置信的兴奋，因为它是已知最早的被子植物——生物学家称之为开花植物的例子之一。

Paleobotanists are still debating what exactly the first type of land plant actually was, but they agree that it was small and moss-like, probably some kind of green algae or liverwort.

古植物学家仍在争论第一种陆生植物到底是什么，但他们一致认为它很小， 像苔藓，可能是某种绿藻或地钱。
