AI Article Synopsis
- A new dynamical theory explains how the genetic code evolved, emphasizing its universal and optimal nature.
- It suggests that early communal life had various collective mechanisms that refined and selected methods for sharing genetic information, rather than traditional Darwinian evolution.
- The theory is demonstrated through a simplified computer model and is contextualized within a series of evolutionary transitions that early life forms underwent prior to vertical descent.
Article Abstract
A dynamical theory for the evolution of the genetic code is presented, which accounts for its universality and optimality. The central concept is that a variety of collective, but non-Darwinian, mechanisms likely to be present in early communal life generically lead to refinement and selection of innovation-sharing protocols, such as the genetic code. Our proposal is illustrated by using a simplified computer model and placed within the context of a sequence of transitions that early life may have made, before the emergence of vertical descent.
