Does evolution select for faster evolvers?

...ority of the DNA in the genomes of some animal and plant species ?including humans, mice, wheat and corn ?came from HGT insertions," Deem said. "For example, we can trace the development of the adaptive immune system in humans and other jointed vertebrates to an HGT insertion about 400 million years ago." ...

Such synchronization can have far-reaching effects. Vandermeer suggests that several well-known biological conundrums, such as the higher-than-expected dive...
