Human breastbone divided into three segments not seven Ex. Tibia and fibula the longest bones in the human body not the humerus He made charts of corpses that were so detailed and “exquisite” that they earned him fame and a steady stream of corpses to study Galen had never dissected a corpse because Roman law did not allow it so he did not have firsthand experience as Andreas did He wrote a new anatomy book to replace Galen’s which he had discredited with research he called his book “The Seven Books on the Structure of the Human Body” or Fabrica. Other scientists such as Darwin used Vesalius’s vast knowledge of the anatomy of the human body to suggest other theories such as evolution Carolus Linnaeus (1707-1798): Tried to classify life Believed he could classify all of life into one single artificial system He had subgroups within groups ex.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
