DESCRIPTION:Trees are self-similar branching structures\, hier
archically organized with longer and thicker branc
hes near the roots. With a mechanically-based nume
rical model\, we show how self-similarity can emer
ge through natural selection. In this model\, tree
s grow into fractal structures to promote efficien
t photosynthesis in a competing environment. In ad
dition\, branch diameters increase in response to
wind-induced loads. Remarkably\, the virtual tree
species emerging from this model have the same sel
f-similar properties as those measured on conifers
and angiosperms.
