The typical response from evolutionists is that perhaps ancient enzymes were different, and more readily mutable to acquire new functions.
Darwin observed that his theory “breaks down” when large leaps of complexity are needed in order to provide some advantage.
Molecular clocks are notoriously unreliable indicators of a lineage’s evolutionary age.
“‘Reverse engineering’ would seem to imply that there was ‘engineering’ in the first place.”
