How (Some) Plants Survived The K-Pg Extinction

The video explores how plants, particularly angiosperms, survived the mass extinction event 66 million years ago through whole genome duplication. This genetic adaptation, known as polyploidy, provided evolutionary advantages during environmental stress. Research shows that these duplications were not random and coincided with the Cretaceous mass extinction, offering plants adaptability in challenging conditions. Modern evidence supports that polyploidy aids in survival in unstable environments, highlighting its role in plant evolution.
