In order to progress our understanding of Quantum Mechanics, we advocate what we call the “geneticist’s approach” in which we introduce mutations to the mathematical genotypes of Quantum Mechanics and study how it affects the physical phenotypes of the theory. We show a few examples of such “mutations” and how the predictions of Quantum Mechanics are affected. We argue that in the process, the physical meanings of various mathematical aspects of Quantum Mechanics will be clarified, and further possible directions of evolution will be evinced.
