Scientists have discovered flowering plants were largely unscathed by the Cretaceous-Paleogene (K-Pg) mass extinction event 66 million years ago, allowing them to take advantage of the new, dinosaur-free planet.
The giant asteroid that snuffed out the dinosaurs at the end of the Cretaceous period left flowers relatively unharmed, and the blooms thrived in the aftermath, a new study has found.
"After most of Earth's species became extinct at K-Pg, angiosperms took the advantage, similar to the way in which mammals took over after the dinosaurs, and now pretty much all life on Earth depends on flowering plants ecologically," study lead author Jamie Thompson, a postdoctoral evolutionary biologist at the University of Bath in England, said in a statement.
To learn more about how flowering plants responded to the K-Pg extinction event, the authors of the new study looked at major flowering-plant lineages previously mapped from DNA mutations of thousands of species.
