Plant Evolution
By 145 million years ago, broad angiosperm leaves with reticulate venation evolved during the rise of flowering plants, enabling efficient photosynthesis and diversification across many environments. The broad leaves of maples and oaks are a successful answer shaped by light, water, and competition.

Did red algae descend from green algae?
Plant Evolution
Wisdom means remembering that resemblance is not relationship, just as correlation is not causation. 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. The wisdom lesson is simple: things that look alike are not necessarily closely related. Appearance is evidence to consider, not a conclusion.

Plant Evolution
From Photosynthesis to Forests
The greening of the planet.
Plant evolution charts the rise of photosynthetic life that reshaped Earth’s atmosphere and made complex ecosystems possible. From early algae to forests and flowering plants, plants transformed climate, soil, and food webs. Understanding plant evolution reveals how life altered the planet long before humans appeared.
