Analysis of 41 plant genomes supports a wave of successful genome duplications in association with the Cretaceous–Paleogene boundary

In 2009, the Van de Peer lab proposed a correlation between whole genome duplications in plants and the Cretaceous-Paleogene extinction event, the most recent mass extinction, which wiped out 70% of all life on earth, including the dinosaurs. Since this finding was met with some skepticism, the researchers have revisited this hypothesis, using 40 whole genome sequences and the most sophisticated evolutionary models and dating techniques available, and ... the story still stands.
