(Blacksburg, Va., April 22, 1999) -- Consider the architecture of modern trees -- the woody strength that builds in rings to support greater and greater height and weight, the protective bark that shields the cells that conduct water and nutrients from the earth to the farthest leaves, and the collars of extra wood that surround the bases of each branch and the way internal layers of wood dovetail at branch junctions to prevent breakage. It must have taken millions of years to evolve such a successful structure.
