26. Origin of Life on Earth
  Previous PageNext Page

The question of the origin of life was studiously ignored by the scientific community for three quarters of a century after Pasteur, with two isolated exceptions: A. I. Oparin in Russia, and J. B. S. Haldane in England.

The very finality of Pasteur's experiments had made chemical inquiry into the development of life from nonliving chemicals not really respectable.


This chapter is concerned with the reawakening of the concept of spontaneous generation in a new, restricted, and scientifically verifiable form.

We do not claim now that it happens all the time; Pasteur took care of that. What we do believe is that the spontaneous generation of life happened once on this planet, and that it then destroyed the conditions under which it could happen again.
