When Competing Viruses Unify: Evolution, Conservation, and Plasticity of Genetic Identities

Area of Science:

• Evolutionary biology
• Virology
• Origin of life studies

Background:

• The quasispecies model, developed in the 1970s, describes RNA evolution based on error-prone replication and mutant populations around a fittest type.
• Early observations revealed complexities in viral behavior, including competition and cooperation, exceeding the original model's scope.
• Individual fittest type-based mechanisms failed to explain the context- and consortia-dependent origin of natural codes.

Purpose of the Study:

• To propose an expanded model for RNA evolution and the origin of natural codes.
• To integrate findings from experimental virology, quasispecies theory, and natural code studies.
• To introduce the concept of quasispecies consortia (qs-c) and the Gangen hypothesis.

Main Methods:

• Theoretical modeling based on quasispecies dynamics.
• Analysis of experimental virology data.
• Comparative study of natural codes and their pragmatic nature.

Main Results:

• Co-operative interactions among RNA agents are crucial for fitness and communication.
• Quasispecies consortia (qs-c) are identified as essential for the evolution of biological group identity.
• The Gangen hypothesis provides a framework for understanding the emergence of group identity, communication, and cooperation.

Conclusions:

• The quasispecies model requires an update to incorporate cooperative dynamics and consortia.
• Natural codes and their evolution necessitate a group-based, rather than individual-based, approach.
• Quasispecies consortia offer a novel perspective on the evolution of cooperation and biological communication.
