Before now, angiosperms (flowering plants) were thought to have a history of no more than 130 million years. The discovery of the novel flower species, which the study authors named Nanjinganthus dendrostyla , throws widely accepted theories of plant evolution into question, by suggesting that they existed around 50 million years earlier. Nanjinganthus also has a variety of ‘unexpected’ characteristics according to almost all of these theories.
Not directly related to cannabis, but kind of cool nonetheless for any botany/biology nerds out there. Turns out there are much older fossils of flowering plants than we expected.
