Is possible for natural selection to change the code?

i have read that the overall of protein charge should be neutralized. And proteins have more Ala, and less His, Cys, Pro, Ser and Leu than would be expected from codon multiplicities alone. can i say that natural selection can change the code?

DNA and Protein Synthesis

... the mutation will be silent, i.e. coding for the same amino acid and you will see no change in protein. Or the amino acid may be very similar (Ala and Val), so you will see change in protein sequence, but it's function won't be altered. Another possibility is that you get some totally different ...

Re: how to memorize the amino acid

... the amino acids as on derivatives of alanine, instead of glycine. Glycine is of course an exception. Proline as well, since it is an imino acid. Alanine is the "basic" amino acid. Now, serine and cysteine are hydroxy- and thiol derivatives. Valine and leucine are dimethyl and isopropyl ...
