A critical case in point was that of reproduction in mammals. The was quite excited by Leeuwenhoek's discovery of microscopic life, which he announced in his famous letters of 7 September 1674 and 9 October 1676, and other microscopists scurried to see for themselves.

Due to their lack of scientific education, this task was hard to make logical scientific conclusions because it is important to obligate scientific rules when someone introduces their scientific work. Proponents search the earth, the solar system, and the universe relentlessly, striving to find evidence of it so as to deny the creation account in Genesis. Rejection of spontaneous generation is no longer controversial among biologists. Anton van Leeuwenhoek 1632 - 1723 was a Dutch tradesman and scientist, best known for his work on the development and improvement of the microscope and also for his subsequent contribution towards the study of microbiology.

Van Leeuwenhoek was the first to see and describe bacteria 1674 , yeast plants, the teeming life in a drop of water such as algae , and the circulation of blood corpuscles in capillaries. He remained there for the rest of his life. He actually gave cells their name after the resemblance he believed they had to a monk's quarters. When he observed the life cycle of fleas and maggots then he described that these organisms do not spontaneously produce then he described the life cycle of insects and process of reproduction. The theory of spontaneous generation held that living creatures could arise from nonliving matter and that such processes were commonplace and regular. Anton van Leeuwenhoek was the first scientist to closely observe cells under a microscope; he paved the way for a modern understanding of biology overall.

He also created at least 25 single-lens microscopes, of differing types, of which only nine have survived.
