Evolutionary history of plants - Wikipedia
Evidence of the emergence of embryophyte land plants first occurs in the middle Ordovician (~ 470 million years ago), and by the middle of the Devonian (~ 390 million years ago), many of the features recognised in land plants today were present, including roots and leaves.

3.2.2: Early Land Plants - Biology LibreTexts
2024年11月26日 · Bryophytes were the first group of plants to evolve on land, followed by the seedless vascular plants. These early plants, accompanied by their fungal mutualists and other microbes, transformed the rocky terrestrial landscape into an ecosystem with stratified soils and complex biotic communities.
The origin and early evolution of plants on land | Nature
1997年9月4日 · From a simple plant body consisting of only a few cells, land plants (liverworts, hornworts, mosses and vascular plants) evolved an elaborate two-phase life cycle and an extraordinary array...
An exceptional and comprehensive study of mostly macrofossil evidence on origins and early diversification of land plants. Also discusses historical theories on the origin of land plants. It is a valuable source of information on both living and extinct plants, and on their traits and evolution.

2021年10月11日 · Here we review the evidence for bryophyte monophyly and consider its implications for the evolution of early land plant evolution based on insights from comparative genomics, comparative developmental biology and the fossil record.
The timescale of early land plant evolution - PNAS
2018年2月20日 · Here we attempt to establish a timescale of early land plant evolution that integrates over the contested topological relationships among bryophytes and tracheophytes. To achieve this, we constructed 37 fossil calibrations with minimum and soft maximum constraints, following best practice .
Land plants arose earlier than thought—and may have had a
2018年2月19日 · While the oldest known fossils of land plants are 420 million years old, researchers have now determined that pond scum first made landfall almost 100 million years earlier.
