11 sept. 1768 - Generation part 2

Description:

Lazzaro Spallanzani suggested that microbes could move through the air to cause what other scientists called spontaneous generation. He also showed that by boiling the microbes in a sample no spontaneous generation would occur suggesting that contamination was the cause of seemingly spontaneous life. His work suggested that all cells come from preexisting cells. This paved the scientific path for Louis Pasteur's work.
