One of the main premises of evolution is connected to random changes o the DNA; mutations, leading to useful changes, which are then chosen by natural selection. The problem with this are the words "random change", since random change on the DNA would lead to more net bad than net good. The net affect of such a mechanism would be some progressive change, for natural selection, but far more negative change that would have life falling like flies, left and right. The latter is not observed.
As a simple home exercise to demonstrate this, close you eyes and randomly point to a word or letter in my opening paragraph. Then replace that word or letter with one that is randomly chosen for you from a dictionary. Do this 100 times and keep track of how many times the meaning becomes messed up, and how many time deeper insight is added.
The paragraph is like the DNA with each letter and word like base pairs and genes. More harm that good will appear if you use random processes to modify the code. Why do you think that proof-reading enzymes were naturally selected to correct typos on the DNA of all cells? The goal was not random change? This was not selected since it contradicts the group viability of natural selection. Wouldn't natural selection have chosen randomizer enzymes instead if the goal was random change?
Darwin's theory of natural selection did not include anything about genes and DNA. This was added decades later. Darwin did not postulate a mechanism for change, but rather empirically observed change and observed a type of natural selection process, among life, that led to new optimizations and better long term viability. This was observed to occur without internal devastation in each generation, due to parallel random changes that do more harm then good. The empirical data describes targeted changes better than random. Proof-reading enzymes to minimize random change gives credence to this.
