I don’t understand how anyone could doubt evolution, look at this for example:
“The genetic code is the mapping of 64 three-letter codons to 20 amino-acids and a stop signal.” It stands out among possible competing codes in several ways. “First, the assignment of amino acids to codons appears to be optimal for minimizing the effect of translational misread errors.” Errors in misreading a codon tend to have minimal effects on the translated protein. “Second, amino acids with simple chemical structure tend to have more codons assigned to them”, as “they are required more often in protein assembly”. But the researchers main interest in the paper below was the ability of the genetic code to carry parallel messages. The list is already impressive (and there is no reason why it should not be extended with research) - binding sequences of regulatory proteins that bind within coding regions, splicing signals that include specific 6-8 bp sequences within coding regions and mRNA secondary structure signals - all higher-order codes that ride over the protein forming code. “They found that the real genetic code could accommodate more arbitrary motifs in coding sequence than almost any of the other possibilities - it has a higher information content. One reason for the real genetic code’s superiority is the fact that its stop codons, when frame-shifted, tend to form common codons, whereas in other codes frame-shifted stop codons form rarer codons or even other stop codons.”
There’s just no way anyone, God included, coulda thought this stuff up. The only way this complexity could have come about is through random mutations.
