"Could you explain to me how Behe's research, which has largely been on the physical chemistry of DNA, shows that species did not evolve from each other?"
I wasn't saying that this is what Behe's research shows. As you are no doubt aware, his work is more related to the structure and operation of sub-cellular organelles.
However, if you are expert in this field, perhaps you can answer a question which I have wondered about for a long time?
Why does a group of 3 nucleotides, when read by a ribosome, encode for a particular amino acid?
No, I'm not aware of that. Back when Behe was actually doing science, he was looking at the p. chem of DNA. I don't count his popular press and un-peer-reviewed meanderings about flagella.
Why does a group of 3 nucleotides, when read by a ribosome, encode for a particular amino acid?
The recognition anticodon of tRNA is three nucleotides. Each tRNA is specific for one amino acid, and it's what recognizes the codon. Two would be an insufficient number to account for 20 amino acids.
You stated:
OTOH creationists look for scientific data which seem to support their theory - i.e. that all species were created as they are and that one species does not develop or arise from another one.
And I asked:
Could you point me in the direction of this research? And what, exactly, would this data look like?
It's a simple question. Where is this research in creationism, and what would the data look like that supports their theory?
