Humans changing allele frequency in dogs by design? Pretty intelligent.
The short legs of a dachshund were not designed by a human, the trait was selected, the ‘design’ was a mutation in a gene for bone length.
The design was God's and he was not the “Incompetent Designer” of Behe’s imagining that is a rank incompetent incapable of making a system that is necessary and sufficient to effect biological change or innovation.
