DESCRIPTION:Trees are self-similar branching structures\, hierarchically o
 rganized with longer and thicker branches near the roots. With a mechanica
 lly-based numerical model\, we show how self-similarity can emerge through
  natural selection. In this model\, trees grow into fractal structures to 
 promote efficient photosynthesis in a competing environment. In addition\,
  branch diameters increase in response to wind-induced loads. Remarkably\,
  the virtual tree species emerging from this model have the same self-simi
 lar properties as those measured on conifers and angiosperms.<br><br><br><
