The fossil record indicates that angiosperms originated about 125 million years ago during the late cretaceous period.
Angiosperms are ascribed from the pollen fossils recovered from the geological material from the Jurassic periods and the imprints of leaves found on the fossils present in cretaceous rocks.
To understand the evolution of angiosperms there are several hypotheses have been developed, but paleontologists are facing various challenges while studying the evolution and clarifying the origin and diversification of angiosperms.
Some botanists believed angiosperms originated from gymnosperms; however; still, they form their distinct species.
During the late Mesozoic era, angiosperms form a sister clade rather than derived from angiosperms, clade developed in parallel with the angiosperms.
The earliest living flowering plant is said to be Amborellatrichopoda, which is the oldest branch of angiosperms.
In the initial angiosperms, there is variation in structure, flower size, or organization, but there is consistency in flower diversity concerning radiation of angiosperms and diversification of the floral forms.
