*During the Late Cretaceous, the Earth's climate was warm and humid, and there was a lot of volcanic activity. These conditions led to the rise of angiosperms, or flowering plants.*

*Angiosperms are the most diverse group of plants, and they include all of the plants that produce flowers and fruits. The first angiosperms were small, herbaceous plants, but over time they evolved into larger trees and shrubs.*

*The first canopy flowers were likely adapted to be pollinated by insects. Insects were abundant during the Cretaceous period, and they were able to reach the flowers of trees and shrubs that were high off the ground.*

*The evolution of canopy flowers was a major event in the history of plant life. It allowed plants to reproduce more efficiently, and it led to the diversification of angiosperms into the wide variety of plants that we see today.*
