- Gymnosperms were once the dominant plant form, but they were outcompeted by angiosperms in warmer areas
Present-Day Distribution of Gymnosperms
- Today, gymnosperms are primarily found in cooler, temperate, and subarctic regions of the world
Evolutionary History of Gymnosperms compared to Angiosperms
- Gymnosperms evolved earlier than angiosperms, with fossil evidence showing that gymnosperms date back to the Paleozoic Era, around 380 million years ago
- Angiosperms, on the other hand, did not evolve until the Cretaceous Period, around 130 million years ago
