Why having extra DNA might have helped some plants survive the K-Pg extinction event.
In short: This video explores how certain plant species managed to endure the massive ecological upheaval of the K-Pg extinction. It examines the theory that possessing a larger amount of DNA may have provided a critical survival advantage during times of extreme environmental stress.
The K-Pg extinction event caused significant ecological disruption, forcing life on Earth to adapt or perish. Research suggests that for plants, the possession of more DNA might have acted as a buffer against these intense pressures.
By maintaining a larger genome, some plants may have been better equipped to navigate the rapid changes in their environment, offering a potential explanation for why certain lineages persisted while others vanished.
