8. Evolutionary Theory/Quantum Mechanics


8. How does evolutionary theory connect with quantum mechanics? Feel free to do a google search to buttress your answers here. Clue: Think of Brian Greene meeting Charles Darwin.


If Briane Greene and Charles Darwin were to meet, and have a conversation, they would definitely argue about the evolutionary theory and quantum mechanics. The argument would probably go something along the lines of the following: Darwin would argue, "matter is composed of indivisible, solid atoms." Greene would then oppose him by stating, "atom is not solid, it has an internal structure consisting of a small, dense nucleus." Darwin has established a theory of evolution which states it occurs from natural selection which occurs at random. On the other hand, Greene established the string theory which states "different particle species of the standard model of particle physics as different aspects of a single type of one-dimensional, vibrating string which are completely random" (wikipedia). The common ground between Evolutionary theory and Quantum Mechanics is mutation and uncertainty. The Quantum Mechanics explain the properties of matter and how it is formed, which continues on to explain "subatomic" particles. The Quantum theory states that it is impossible to predict how an individual particle will behave or to find the exact position of it. The Evolutionary theory states that there are changes in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift, according to dictionary.com. The Darwinian model of the evolution of cells states when cells are undergoing mutation, they get rid of all of the negative factors the organism may have. The Quantum theory is an attempt to explain why mutations occurs. Through the use of Quantum theory, we are able to explain the reason behind mutation and evolution, making them connect. Mutations occur by quantum events, but at random times. Additionally, it is impossible to predict the position of an electron which is on the "subatomic" level. Similarly, it is quite impossible to guess when a mutation is going to occur under the theory of Evolution.
