During his life he made more than 500 lenses and some twenty-five different microscopes. His researches on lower animals refuted the doctrine of spontaneous generation, and his observations helped lay the foundations for the sciences of bacteriology and protozoology. What is the role of DNA? Van Leeuwenhoek’s discovery of “animalcules”, “I then most always saw, with great wonder, that in the said matter there were many very little living animalcules, very prettily a-moving. 1 synonym for animalcule: animalculum.
