A new global study has revealed the first complete evolutionary tree of the Earth's flowering plant families, showing how the group rose to world domination.
Or it could be linked to the time when angiosperms started to dominate ecosystems, argues evolutionary ecologist Mark Westoby of Macquarie University who also wasn't involved in the work.
Interestingly, the length of this delay diversifying into modern-day species varies among different types of ecosystem, Dr Ramirez-Barahona says. While the mass extinction event at the end of the Cretaceous period nearly wiped out all the dinosaurs, it left the angiosperms relatively unscathed. What's more, "the changes that happened globally that brought the dinosaurs to extinction may have actually opened up habitats that allowed the angiosperms to move forwards", Professor Pam Soltis says.Some of Australia's plants might not be as old as you'd think
