The author, Dean Schulz, an engineer with a PhD in computer science, takes a “bottom up” approach.
The genetic variation in any species is confined to a limited set of variables such as a finch beak’s thickness.
Design motifs such as four-bar linkages and control systems must meet exacting requirements whether implemented in a space shuttle or a fish.
Purported examples of poor design usually represent opinions resulting from armchair critics’ limited understanding of the technical literature.
Proponents of intelligent design would agree that biology is imperfect and biomedicine should be encouraged to cure diseases and fix problems.
