Epistolution: a new principle necessary to a learning-first theory of life

Communicative & Integrative Biology
Biological theory assumes the organized appearance of life and the reliable recurrence of traits are due to inheritance. Natural selection acting on blind variations produces phenotypes with heritable traits, one of which may be natural learning. The aim
