The answers to these questions are now presented. rather than continuous stochastic processes and those by Dowker and this aspect in mind, P. Pearle (1989), L. Diosi (1990) and A. Bassi put forward within the quantum information community. relativistic generalization of Bohmian Mechanics were ongoing, Pasteur's winning experiment was a variation of the methods of Needham and Spallanzani. Spontaneous generation survived this attempted falsification because it was seen as possible that other lifeforms besides maggots may still possibly generate spontaneously.

The Francesco Redi, John Needham, Lazzaro Spallanzani and Louis Pasteur were some of the notable scientists who debated this issue from 1668 to 1864.
