The Origin of Life

Post-script: The Cosmic Ancestry of Organic Matter

An alternative hypothesis to that outlined above, is that the process of organic synthesis took place not on Earth, but during the process of stellar or planetary formation. It may be that quite complex organic molecules were delivered to earth already formed. There is some evidence to support this hypothesis, for some interstellar dust particles and some meteorites contain complex organic molecules. The topic of a cosmic ancestry for life has been given the grand title 'panspermia' and there is a helpful web site at http://www.panspermia.org/index.htm (see especially http://www.panspermia.org/oseti.htm).
