Summary:
Jets of cosmic rays from colliding stars can produce lethal amounts of muons in the earth's atmosphere, destroy the ozone layer and radioactivate the environment. The three astrophysicists who first proposed that some of the earth's great extinctions were caused by such events now propose that the radiation produced would also cause mutations that create new species in surviving life.

NEW YORK, N.Y., and HAIFA, Israel, July 9, 1998 -- Jets of cosmic rays from colliding stars can produce lethal amounts of muons in the earth's atmosphere, destroy the ozone layer and radioactivate the environment. The three astrophysicists who first proposed that some of the earth's great extinctions were caused by such events -- Arnon Dar, Ari Laor, and Nir Shaviv from the Technion-Israel Institute of Technology -- now propose that the radiation produced would also cause mutations that create new species in surviving life. Their doom and creation theory is published in the June 29 Physical Review Letters.
