Sudoku Theories
If some of the more contentious theories of the day could be expressed as Sudoku puzzles, then I think this is how Intelligent Design would look:
+---+---+---+
|...|...|...|
|...|...|...|
|...|...|...|
+---+---+---+
|...|.3.|...|
|..1|2.4|5..|
|...|.6.|...|
+---+---+---+
|...|.7.|...|
|...|.8.|...|
|...|.9.|...|
+---+---+---+
|...|...|...|
|...|...|...|
|...|...|...|
+---+---+---+
|...|.3.|...|
|..1|2.4|5..|
|...|.6.|...|
+---+---+---+
|...|.7.|...|
|...|.8.|...|
|...|.9.|...|
+---+---+---+
There appears to be an artifice present. However, unless you revere the central premise as a mystery not to be questioned, you will see that it is unsolvable.
On the other hand, Darwin's puzzle is the work of a blind man:
+---+---+---+
|1..|...|..7|
|...|.5.|...|
|...|...|...|
+---+---+---+
|.4.|...|...|
|...|2..|...|
|...|...|..9|
+---+---+---+
|...|...|...|
|...|..8|...|
|.6.|...|3..|
+---+---+---+
|1..|...|..7|
|...|.5.|...|
|...|...|...|
+---+---+---+
|.4.|...|...|
|...|2..|...|
|...|...|..9|
+---+---+---+
|...|...|...|
|...|..8|...|
|.6.|...|3..|
+---+---+---+
Random, with many unknowns.
Yet, somehow, it works.
