The Anthropic Multiverse Origin of Life

"Quantum measurement by a self-replicating biomolecule was the key event that caused life to emerge."

Try to follow me on this:

"Using the Many Worlds approach, peptide addition within the first (proto-) cell would have taken place, not in a classical universe, but within the multiverse of all possible states."

"Each peptide addition was a multiple branch point where the growing peptide chain evolved in all directions simultaneously. The multiverse expanded with every addition to the peptide chain as the quantum tree of possibilities grew in every direction."

"But once one branch lighted upon a self-replicating peptide, then quantum measurement would have become inevitable. Decoherence shattered the unity of the quantum tree, which split into 20^32 separate branches, each representing a different universe. Only one of the 20^32 descendent universes harboured the self-replicator, but in that one universe life emerged."

The 20^32 is the amount of ways possible to put together peptides 32 amino acids long.

Please comment on what you think about this interpretation of how life first emerged. All of this was taken from molecular geneticist JohnJoe McFadden's book Quantum Evolution.
