Redrafted it so it asks for different answers to a general question rather than whether the poster's answer to this question is correct.

| Mar 27, 2022 at 16:50 | comment | added | Retracted | @David I think I understand now that the unit that natural selection is operating on here is the boundaries between amino acids in codon space, rather than the codons themselves. It is different enough conceptually that I maybe should write another question. | |
| Mar 23, 2022 at 19:57 | comment | added | David | Could you clarify what you mean by “this would make sense”? Things only make sense in relation to a conceptual framework, and in this case you are presumably making some assumption about the way the genetic code evolved. I can guess what your assumption is, and if my guess is correct, almost certainly do not share it, but if you must ask questions like this and want an intelligent discussion you must spell your assumptions out. And changing met to trp doesn’t alter the fact that the situation with met is inconsistent with your proposition. How do you accommodate it? | |

| Mar 22, 2022 at 10:35 | comment | added | David | Welcome to SE Biology. We do expect people to do a little research before posting to try to answer questions themselves. Theoretical questions like this can only be approached by logical arguments, which anyone with basic biochemical knowledge can try. So ask yourself, would a change in methionine be unimportant? If you consider the mechanism of initiation of protein synthesis, I think you can reject that hypothesis. The fact that this hypothesis was not considered in the question you link to is also suggestive. A simpler idea is that the structurally simpler amino acids evolved first. | |
