HORIZONTAL EXPLANATION. “Then, why only one frozen accident, assuming that the actual codon assignments are indeed (quasi) accidental? To put it even more generally, why a single last universal common ancestor only? Only one code survived because extensive horizontal gene transfer was an aspect of early evolution without which the transition to the cellular level of complexity would not have been possible. Even a small change in the code has a prohibitive effect on horizontal gene transfer.”
