quantum evolution

Abstract
The principle that mutations occur randomly with respect to the direction of evolutionary change has been challenged by the phenomenon of adaptive mutations. There is currently no entirely satisfactory theory to account for how a cell can selectively mutate certain genes in response to environmental signals. However, spontaneous mutations are initiated by quantum events such as the shift of a single proton (hydrogen atom) from one site to an adjacent one. We consider here the wave function describing the quantum state of the genome as being in a coherent linear superposition of states describing both the shifted and unshifted protons.

The theory of quantum evolution is a radical new take on how mutations in DNA occur. Basically the theory postulates that DNA molecules are in fact macroscopic quantum objects that undergo quantum interference. It is spearheaded by Johnjoe McFadden, a professor in the UK and makes for an interesting read. Here is a brief overview of the main ideas of the theory. He also has some interesting ideas about a possible interaction between electromagnetic fields and consciousness.

Profesor Anton Zeillinger's group in Vienna have recently demonstrated that the fullerene molecule, composed of 60 carbon atoms (the famous ”buckyball’), can pass through two slits simultaneously. Few physicists doubt that as the technology advances, bigger and more complex systems will be shown to inhabit the quantum world. Fullerene molecules are spheres with a diameter similar to that of the DNA double helix. If fullerene can enter the quantum multiverse then DNA may do the same.
