o matter which part of a leaf we exam-
ine, we see evidence of an infinite intel-

ligence and artistry. When a leaf is
viewed from the outside, its shape and
structures display a design aimed at a
particular purpose. For example, the leaf needs to re-
main flat in order to receive the maximum amount of
solar rays but for that to be possible, the leaf must
have a special design. Comparing the leaf to a piece of
typing paper will give a better idea about its design,
essential for the leaf to retain its flattened contour.

When you want to hold a newspaper or piece of
paper straight, the paper bends over and folds in two.
To keep the paper rigid, you have to impart a slight
crease or bend from one side to the other. Leaves also
need such a crease in order to stay flat.
Leaves can stay flat and obtain the maximum
benefit from solar rays by the main vessels in their

structures known as midribs. These vessels pass
through the center of the leaf and connect it back to
the stem. Moreover, other veins also emerge from the
midrib and spread to the surface of the leaf. The mid-
rib and these lateral veins constitute a flexible skele-
ton that permits the leaf to remain relatively rigid. 1
How did every one of the infinitely many leaves
on Earth come to have the venous system necessary
for them remain rigid? It is of course impossible for a

leaf to realize on its own accord how it can make the
