Flowers are the most recent plant structures to have evolved. They first appeared in the fossil record around 130 million years ago, while seeds and cones are much older, dating back to around 360 million years ago. The vascular system, which enabled plants to transport water and nutrients, also evolved much earlier than flowers.
