Plants.
10 random takeaways.
1.
Red and green algae diverged about 1.5 billion years ago, shaping marine ecosystems. Green algae later gave rise to land plants around 475 million years ago, transforming Earth’s surface and atmosphere. Fun fact: blue-green algae aren’t algae at all. They’re photosynthetic bacteria that emerged much earlier, around 2.7 billion years ago.
2.
From History:
Ginkgo represents an ancient seed-plant lineage going back 270 million years ago. It is distinguished by its fan-shaped leaves with radiating, dichotomous veins, a durable leaf architecture that has persisted for hundreds of millions of years.
3.
From History:
By 385 million years ago, trees started to emerge. Distinguished by their secondary growth wood and deep roots, trees grow toward the Sun and deep into the ground. Although we think of trees as stoically still, even the quiet forest is in motion, pulsing with water and light.
4.
From History:
By 2.4 billion years ago, bacteria are added to cells and within the archaea group and eukaryotes emerge. You are a walking ecosystem. A Chimera, a hybrid creature made of an Archaea host and trillions of Bacterial power-plants. Without that theft 2 billion years ago for the massive energy boost needed for muscle and brains, life would likely still be just a thin layer of slime on the ocean floor.
5.
From History:
By 450 million years ago, fungi and plants started a rich dirt alliance. Forests grew because fungi fed them. Plants exchanged sugars for fungi phosphors and minerals.
6.
From History:
Plants, fungi, and animals trace their deepest cellular ancestry through archaea. Eukaryotic life did not arise from bacteria alone, but from an archaeal host that partnered with bacteria.
7.
From History:
Evolution sometimes refines structure. Other times it rewrites strategy. About 130 million years ago, flowers evolved. It was the early Cretaceous, a time when a branch of evolution transformed seed-plant reproduction into enclosed ovules and eventually partnering with pollinators.
8.
From History:
The Mesozoic era starts with the end-Permian mass extinction 252 million years ago ending the reign of our synapsid ancestors. Within it, it includes the end-Triassic extinction 201 million years ago and the Toarcian environmental crisis 183 million years ago. The Mesozoic era ends the reign of dinosaurs with the K–Pg extinction 66 million years ago.
9.
From History:
By about 1.65 billion years ago, major single-celled eukaryotic lineages diverged into ancestral paths that would eventually lead to multicellular plants, fungi, and animals. Various cell adhesion and communication mechanisms evolved repeatedly across different lineages.
10.
From History:
Connection spreads life, but separation often sharpens it. When populations are cut off from one another, evolution calls that vicariance. It’s the start of running separate experiments. Over deep time, distance becomes difference.
