The Science of Plant Evolution — From Algae to Orchids

Life Begins in Water — The story of plants starts with green algae, simple aquatic organisms that mastered photosynthesis over a billion years ago.
The Great Land Leap — Around 470 million years ago, plants made the bold move from sea to soil, paving the way for life on land.
The Rise of Mosses and Liverworts — These pioneers anchored to rock and soil, forming the first green carpets on Earth’s barren surfaces.
Roots and Vessels Emerge — Early vascular plants evolved internal plumbing—xylem and phloem—to transport water and nutrients efficiently.
Ferns and Forests Flourish — Towering fern trees of the Carboniferous period created vast forests that transformed Earth’s atmosphere.
Seeds Change Everything — The evolution of seeds protected embryos and allowed plants to conquer dry land and new environments.
The Reign of Flowering Plants — About 140 million years ago, angiosperms evolved flowers and fruits, revolutionizing reproduction and ecology.
Pollinator Partnerships — Flowers coevolved with insects, birds, and bats, creating the dazzling diversity of shapes, scents, and colors we see today.
From Pines to Petals — While gymnosperms like conifers still dominate cold climates, flowering plants now rule most of the planet.
An Ongoing Evolution — From ancient algae to elegant orchids, plant evolution continues—adapting to new climates, species, and human influence.
