Solar UV Radiation as a Selective Force in the Evolution of Terrestrial Plant Life

  • Martyn M. Caldwel
Part of the NATO Conference Series book series (NATOCS, volume 7)


This paper will briefly reflect on the possible role of solar UV in the early stages of evolution of terrestrial plants and will examine a steep gradient of natural solar UV-B that currently exists on the Earth.
