| 9. | The origin and evolution of land plants was an important event in the history of earth life and has affected all other lives on the earth and global environment . during the past two decade , the new discoveries of fossil plants microfossils and megafossils from the mid - ordovician through all silurian to the lower devonian improved knowledge of the origin of land plants , provided a time framework of the basal groups for the land plants and the early evolution diversity of vascular plants . three new plant based epochs have been recognized . on the other hand , molecular sequence studies have provided insights into the phylogeny and early branches of land plants . a phylogenetic tree has been established by the joint of a study of comparative morphology and gene sequences . this paper summarizes recent advances and new knowledges , comments on the phylogenetic studies based on the cladistic analysis
陆生植物的起源和演化是地球生命中的重大事件，它影响到地球上所有的其他生命和全球环境。在过去的20年中，从中奥陶世历经整个志留纪至早泥盆世的岩层中，化石植物微化石和大化石的新发现改变了人们对陆生植物起源的认识，并且为陆生植物和维管植物早期演化分异提供了基部类群分化的时间框架。据此人们识别出地史中的3个陆生植物的时代：始胚植物时代始维管植物时代和真维管植物时代。 |
