The evolutionary strategy of DNA acquisition as a possible reason for a universal genetic code.
The evolutionary strategy to generate genetic variants by DNA acquisition involving horizontal gene transfer seems to be widely used by many, if not all, living organisms. A common language between donor and recipient organisms, as provided by the quasi universality of the genetic code, can favor the effectiveness of the DNA acquisition strategy. These considerations are here discussed in the context of our knowledge on the natural strategies of molecular evolution and on the commonly used genetic code.
