Which best explains the evolution of gymnosperm plants? They evolved at the same time as monocots and dicots. They evolved after the seeded flowering plants. They evolved after the seedless vascular plants. They evolved before the seedless nonvascular plants.

They evolved after the seedless vascular plants.

Explanation:
