DNA Duplication: A Mechanism For 'survival Of The Fittest' | Medical News »
Posted By fanssites 9 months, 1 week ago in Health & Fitness150 years after Darwin published his theory of evolution, VIB researchers connected to Ghent University 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. The doubling of their DNA made these plants the ‘ fittest’ for surviving the altered climatic conditions, a mechanism that is probably also found in vertebrates.
The end of an era
