Plant evolution is an aspect of the study of biological evolution, predominantly involving evolution of plants suited to live on land, greening of various land masses by the filling of their niches with land plants, and diversification of groups of land plants.
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.
1 mar 2023 · These will elucidate the nature of ancestral Archaeplastida, Viridiplantae, and Streptophyta, and will highlight variation within early plant lineages. Model organisms will also be vital to establish the function of genes across early plant evolution and within younger plant ancestors.
13 wrz 2024 · The evolutionary history of plants is recorded in fossils preserved in lowland or marine sediments. Some fossils preserve the external form of plant parts; others show cellular features; and still others consist of microfossils such as pollen and spores.
31 paź 2022 · Inferring the timescale of early plant evolution is crucial for understanding the environmental context of plant evolution, the coevolution of fungi, bacteria, and animals [12,13,104], and transformations in biogeochemical and atmospheric cycles [4,105].
The study of plant evolution attempts to explain how the present diversity of plants arose over geologic time. It includes the study of genetic change and the consequent variation that often results in speciation , one of the most important types of radiation into taxonomic groups called clades .
31 paź 2022 · Plant (archaeplastid) evolution has transformed the biosphere, but we are only now beginning to learn how this took place through comparative genomics, phylogenetics, and the fossil record.
