Answer:
They were all part of the scientific revolution
Explanation:
William Harvey
Through dissection, Harvey (1578-1657) was the first to demonstrate that the circulation of blood through the human body is continuous, rather than consisting of different types circulating through the veins and arteries, as had been previously assumed by the ancient Greek physician, Galen.
Andreas Vesalius
As a student and professor in Belgium and Paris, Vesalius (1514-1564) was educated in the anatomical works and theories of the ancient Greek physician Galen, whose views on anatomy had long been the standard in Europe. Vesalius questioned Galen's authority, and published On the Fabric of the Human Body in 1543. It is considered the first great modern work of science, and the foundation of modern biology.
So Andreas Vesalius, William Harvey, Anton van Leeuwenhoek and
Robert Hooke made historic advances in our understanding of living things,
yet were not responsible for true paradigm shifts or concepts of major
significance. ‘There emerged no theory of protozoans, theory of human
anatomy and physiology, or theory of insect structure – nor could any
theories emerge since no fundamental questions were being asked, no major
hypotheses being tested.’
