How did lazzaro spallanzi contribute to biology?

Lazzaro Spallanzani was an Italian physiologist who made important contributions to the experimental study of bodily functions and animal reproduction. His investigations into the development of microscopic life in nutrient culture solutions paved the way for the research of Louis Pasteur.

His first biological work, published in 1767, was an attack on the biological theory suggested by Georges Buffon and John Turberville Needham, who believed that all living things contain, in addition to inanimate matter, special “vital atoms” that are responsible for all physiological activities.As a result of this work, he concluded that the objects in pond water and other preparations were living organisms introduced from the air and that Buffon’s views were without foundation.

The range of Spallanzani’s experimental interest expanded. The results of his regeneration and transplantation experiments appeared in 1768.
