Fossils challenge assumptions on how animals adapted to land化石挑战了人们对动物如何适应陆地生活的固有认知。
New research presents analysis of rare fossils which scientists say fill knowledge gaps on the development of the creatures that gave rise to the first land-dwelling vertebrates.

Scientists have long posited the earliest water animals to transition to land had amphibious tadpole features, going through a metamorphosis akin to that of today’s frogs.
But new research out recently in the journal Science challenges that conventional assumption.

科学家们长期以来一直认为，最早从水生动物过渡到陆地的动物具有两栖蝌蚪的特征，经历了类似于今天青蛙的变态发育过程。
但最近发表在《科学》杂志上的一项新研究对这种传统假设提出了挑战。
