Quick Summary

Evolutionary botany traces the history of plants, from their earliest terrestrial colonization around 500 million years ago to the diverse plant communities of today. This field uses fossils and genetics to understand how plants have evolved in complexity and diversity. Key developments include the emergence of vascular plants (tracheophytes), the evolution of seeds in gymnosperms, and the subsequent dominance of flowering plants (angiosperms). The study of evolutionary botany also examines how plants have adapted to various environments and how their evolution has shaped entire ecosystems. George Ledyard Stebbins, Jr. is recognized as a foundational figure in this field for applying modern evolutionary theory to plants.123
