Evidence for Evolution

 
Here's another one of those videos that are supposed to prove evolution. Before you watch it, let me give you the counter-argument. The amino acid glutamate is encoded by two different codons GAA and GAG. There is no bias in favor of one or the other so evolution would predict that the codons for glutamate can freely mutate from GAA to GAG or from GAG to GAA. If we examine several different species then we expect to see differences in the glutamate codons according to the neutral theory of evolution.

However, when we look at all the glutamate codons from α- and β-globin genes in humans, chimps, and monkeys we see that all the codons are identical. There has not been one single change as predicted by evolution. The chance of this happening if evolution is correct is 16 million to one. Thus, these genes must have been designed by an intelligent being who choose to use the same DNA sequence for all primates.

I don't like Intelligent Design Creationism. It's bad science. However, we aren't going to win any arguments by using silly examples that can easily be refuted by anyone with a brain. Is this is an example of the sort of framing that we're supposed to be practicing?
