Origins of life II: Cosmic evolution, abundance, and distribution of biologically important elements; Proceedings of the Second Conference, Princeton, N.J., May 5-8, 1968.Attention is given to important astronomical observations, the source of atmospheric hydrogen, and the primordial abundance of the elements. The evolution of the earth's atmosphere is discussed together with some physical facts about Venus and Mars. The likelihood that Mars produced an atmosphere in the past is investigated, taking into account present equilibria between the surface and the atmosphere, and the evidence regarding a past atmosphere.
