Version 5 Biochemical ‘Cambrian’ explosion-implosions: the generation and pruning of genetic codes

Abstract

Tlusty’s topological analysis of the genetic code suggests ecosystem changes in available metabolic free energy that predated the aerobic transition enabled a punctuated sequence of increasingly complex genetic codes and protein translators. These coevolved via a ‘Cambrian explosion’ until, very early on, the ancestor of the present narrow spectrum of… (More)
