The sequences that encode for the best functions will be preserved and eventually dominate the population.
Invoking a designer sitting at a work bench whittling away at sequences is superfluous when the struggle to reproduce/survive shapes the sequence over time.
Now I invoke a ‘designer sitting at a work bench whittling away at sequences’? These imaginary arguments are… not intelligently designed.
Where does a ‘struggle’ to do anything exist within purely naturalistic constraints? Is nature invoking ‘struggle’? Where does ‘survive’ exist within purely naturalistic constraints? Is nature invoking ‘survival’? Whittle me this batman….
