DNA Duplication: A Mechanism For 'Survival Of The Fittest'

Scientists have discovered that DNA duplications have given plants an evolutionary advantage. This mechanism enabled plants -- in contrast to the dinosaurs -- to survive the Cretaceous-Tertiary mass extinction of 65 million years ago. With the aid of the latest bioinformatics technologies, the researchers have been able to closely estimate the timing of known DNA duplications in a number of plant species.
